Using reactjs and javascript - Chrome does not offer to remember passwords - google-chrome

Hi I ran into the bug where Chrome does not offer to remember userid & passwords.
I tried the solution in link below but I could not get it to work. Has anybody solved this for React?
http://code.google.com/p/chromium/issues/detail?id=43219
I implemented the solution in the above link but it did nothing when using react.
Many Thanks!
Sample Code as requested:
The original workaround is described in the link above - I have included here:
This is a Chrome bug and here is the recommended workaround:
http://code.google.com/p/chromium/issues/detail?id=43219
As a followup to comment #5, here is a fuller explanation of a workaround that I have tested.
On your login page, include a form with two input elements. Set the name and id of one to "userid" and the other to "password". E.g.,
<input value type="text" id="userid" name="userid" autocomplete="on">
<input value type="password" id="password" name="password" autocomplete="on">
Give the form a POST action to a blank html page served from the same domain, say blank.html. Set the onsubmit handler to a JavaScript function:
<form name="login" id="login" method="POST" action="blank.html" onsubmit="return do_login();">
Above the form, include a hidden iframe element, like so:
<iframe src="login.html" style="width:0px;height:0px;border:0px;" id="hidden" name="hidden"> </iframe>
The login.html file must also be served from the same domain, and it should contain an identical form (same names and ids, same action and method) as the one on the real login form.
In your JavaScript do_login handler, perform the authentication however you like. To get Chrome to prompt the user to store the password, have the JavaScript code copy the values from the real form to the hidden form, then submit the hidden form, like so:
var userid = document.getElementById("userid").value;
var password = document.getElementById("password").value;
var iframe = document.getElementById("hidden");
var iframedoc = iframe.contentWindow ? iframe.contentWindow.document : iframe.contentDocument;
var fake_login_form = iframedoc.getElementById("login");
var fake_userid = iframedoc.getElementById("userid");
fake_userid.value = userid;
fake_password.value = password;
fake_login_form.submit();
Tested with Chrome 10.0.648.204.
Here is what I did for React:
I created a 'blank form' and configured an nginx rule:
Included a dummy login form which is rendered and hidden:
Note: I am using react-frame-component
/**
* #jsx React.DOM
*/
'use strict';
var React = require('react/addons');
var Frame = require('react-frame-component');
var Input = require('react-bootstrap/Input');
var DummyLoginForm = React.createClass({
_onChange: function(){
console.log('DummyLoginForm onChange called')
},
_onSubmit: function() {
console.log('DummyLoginForm onsubmit called');
var email = this.refs.userid.getValue();
var password = this.refs.password.getValue();
console.log(email);
console.log(password);
},
render: function () {
var content = (
<div>
<Frame id="hidden" width="0" height="0" name="hidden">
<form role="form" name="dummylogin" id="dummylogin" ref="dummylogin" method="POST" action="/login/index.html" onsubmit="return _onSubmit();">
<input value type="text" id="userid" name="userid" ref="userid" autoComplete="on" onChange={this._onChange}/>
<input value type="password" id="password" name="password" autoComplete="on" onChange={this._onChange}/>
</form>
</Frame>
</div>
);
return content;
}
/*jshint ignore:end */
});
module.exports = DummyLoginForm;
In the real login modal I do this:
I am using react-bootstrap modal
onSubmit: function(e) {
if(e && typeof e !== 'undefined') {
e.stopPropagation();
e.preventDefault();
}
var email = this.refs.email.getValue();
var password = this.refs.password.getValue();
MyUtils.login(email, password);
// workaround to force chrome to prompt to save password details
if(BrowserUtils.isChrome()) {
console.log("Chrome");
var iframe = document.getElementById("hidden");
var iframedoc = iframe.contentWindow ? iframe.contentWindow.document : iframe.contentDocument;
var fake_login_form = iframedoc.getElementById("dummylogin");
var fake_userid = iframedoc.getElementById("userid");
var fake_password = iframedoc.getElementById("password");
fake_userid.value = email;
fake_password.value = password;
fake_login_form.submit();
}
},
The _onSubmit: function() in DummyLoginForm does not get triggered

show the inputed email in the next page above the password field in

I am creatig a login system. I want the user to input the email and then click next. Then the user will be redirected to the password input page. I want to put he email that the user has typed above the password field.
Do someone know how to do it?
You can use forms to do this, but really we try not to use forms anymore. A more modern way is to use localStorage.
Also, you cannot do this with just HTML and CSS. You need to use javascript also.
Here is an example of how it might work.
PAGE ONE:
<label for="emlInput">Email: </label>
<input type="email" id="emlInput" />
<button id="btnNext">Next</button>
<script>
document.addEventListener("DOMContentLoaded", function() {
const btnNext = document.getElementById('btnNext');
btnNext.addEventListener("click", advancePage, false);
});
function advancePage() {
const elEml = document.getElementById('emlInput');
localStorage.setItem('eml', elEml.value);
window.location.href = "t2.html";
}
</script>
PAGE2
<div>
<h2>Password For: <span id="emlSpan"></span></h2>
</div>
<label for="pwd">Password: </label>
<input type="password" id="pwd" />
<script>
document.addEventListener("DOMContentLoaded", function() {
const ls = localStorage.getItem('eml');
const eml = document.getElementById('emlSpan');
eml.innerText = ls;
});
</script>

google.script.run.withSuccessHandler does not work properly

I have a HTML code setup within my Google Apps Script project which basically validates the userid and password provided that pair exists in the gSheet or not and according to the verification I either show an alert or redirect to another web-page. When I deploy the code as a web-app, HTML renders just fine, submit button works and executes the gs code however it does not return the value back to the withSuccessHandler function of JS inside the script tag in the HTML code.
I have read a couple of very identical queries in the forum and followed exactly the same path, however I couldn't be able to succeed. For example like this post
It seems there's something that my eyes and mind cannot see - what is it?
Here is the HTML
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<div>
<form id="user_login">
<input type="text" name="userid" id="userid" placeholder="enter username"/>
<input type="text" name="pswrd" id="pswrd" placeholder="enter password"/>
<input type="submit" name="login" id="login" value="LOGIN"/>
</form>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<script>
$('#login').click(function() {
console.log("Form submitted...");
google.script.run
.withSuccessHandler(function(response) {
console.log(response);
if (response == true) {
window.open("http://www.google.com", "_self");
} else {
alert("Some alert message here")
}
})
.checkName({
userid: $('#userid').val(),
pswrd: $('#pswrd').val()
});
});
</script>
</body>
</html>
And here is the gs functions
var html;
var verified;
function doGet() {
html = HtmlService.createTemplateFromFile('myformtest').evaluate().setTitle('Web App').setSandboxMode(HtmlService.SandboxMode.NATIVE);
return html
}
function checkName(form){
Logger.log("Form info > "+JSON.stringify(form));
Logger.log("Userid > "+form.userid);
Logger.log("Pwd > "+form.pswrd);
verified = false;
var ss = SpreadsheetApp.openById("1rard7vdpjmfrN81oi2ARhMlLGdNSxC7MqoIw2soj25E").getSheetByName("names");
var values = ss.getDataRange().getValues();
for(n=1;n<values.length;++n){
var username = values[n][0]; // 1 is the index of the column starting from 0
var password = values[n][1];
Logger.log("username: "+username+" | password: "+password);
if (username == form.userid && password == form.pswrd) {
Logger.log("User found in Row("+(n + 1)+")");
verified = true;
break;
}
}
Logger.log("User verified? "+verified);
return verified
}
I can log that the JS is fired correctly with passing the form parameters to the gs function correctly and the gs function executed correctly as well. However, it does not return the true/false value back to the handler function inside the JS.
I expect that when the checkName function is executed, to return the variable's value back to the JS that is to be processed within the withSuccessHandler function and resulting with either redirecting to a definite URL or displaying an alert message.

Multiple <form> tags in different locations with the same target iframe?

I have an iframe in the content area:
<iframe name="my_iframe" frameBorder="0" height="200" src="about:blank"></iframe>
I have a submit-button under it:
<form action="includes/action.php" method="post" target="my_iframe">
<input type="submit" value="Submit">
</form>
And I want some checkboxes in another area:
<form action="includes/action.php" method="post" target="my_iframe">
<input type="checkbox" name="option">
</form>
But it doesn't work, the submit-button works but it doesn't send the checkbox.
I can't put everything in one -tag because I want the checkbox in a sidepanel of the main-view and the submit-button on a page that is in another page. (Loaded per ajax? I'm using frameworks7 btw.)
Is it not possible with different form-tags or is it because of the ajax thingy?
EDIT1: I managed to build an example for easier understanding with plunker, it doesn't work with php and I don't have a webspace right now, but you get the idea.

UPDATE 2
To get a cleaner result without the stale cache confusing tests I have updated it, please review newest update:
http://plnkr.co/edit/34KOyh9rIEGV3bXNsD9F?p=preview
UPDATE
Now that I was provided with a very complete and nicely coded demo, I have solved your problem.
http://plnkr.co/edit/Z2I1Q2swIXmFfynalaLB?p=preview
Note: I'm using a test server, so the cache may be stale. Just change the action by adding a number to the end.
Example
change:
http://www.hashemian.com/tools/form-post-tester.php/so_post_chk
to:
http://www.hashemian.com/tools/form-post-tester.php/so_post_chk1
When the checkbox is checked, your result should be cache=on
When the checkbox is not checked, your result should be cache=
You could assign one or more inputs (usually type="hidden") outside of the forms and collect whatever data from anywhere on the page regardless of which form it originated from.
http://plnkr.co/edit/er5RoJ049xSBwtR7gtTI?p=preview
This demo revolves around a simple JS function:
function toOutput(x) {
var str = x.toString();
var out4 = document.getElementById('out4');
out4.value += str;
}
Note the special condition for checkboxes:
if(this.checked) {
toOutput(this.value);
text1.value += this.value;
};
It's needed because when the click event is triggered on a checkbox, it is considered on every click checked and unchecked. I assume that the checkbox value is collected when it's actually checked.
I got option onsubmit form ...
Try it:
Create test.php file:
<form id="myForm" action="includes/action.php" method="post" target="my_iframe">
<input onclick="myFunction()" type="submit" value="Submit">
</form>
<form action="includes/action.php" method="post" target="my_iframe">
<input id="cbopt" type="checkbox" name="option" value="option" checked="checked">
</form>
<script>
function myFunction() {
var y = document.createElement("input");
y.setAttribute("type", "checkbox");
y.setAttribute("value", "option");
y.setAttribute("name", "option");
y.setAttribute("checked", "checked");
document.getElementById("myForm").appendChild(y);
var x = document.getElementById("cbopt").name;
document.getElementById("demo").innerHTML = x;
var z = document.forms.length;
document.getElementById("demo").innerHTML = z;
}
</script>
Code for includes/action.php :
<iframe name="my_iframe" frameBorder="0" height="150" width="555" src="about:blank">
<p id="demo"></p>
</iframe>
<?php
//$site = $_POST['doorde'];
//$url = $_POST['doordie1'];
$opt = $_POST['option'];
echo $opt;
?>
Try and comment me ...
Here's what you can do, copy the values from one form to the other before submitting, making sure you remove fields added previously when you submit again.
<form action="includes/action.php" method="post" target="my_iframe" id="myform">
<input type="submit" value="Submit">
</form>
<form action="includes/action.php" method="post" target="my_iframe" id="otherform">
<input type="checkbox" name="option">
</form>
<iframe name="my_iframe" frameBorder="0" height="200" src="about:blank"></iframe>
<script>
function copyFormFieldsIntoHiddenFields(from, to) {
var elementsAdded = [];
for (var i = 0; i < from.elements.length; i++) {
var nodeToCopy = from.elements[i];
// Unchecked checkboxes do not get sent to server
if (nodeToCopy.type != "checkbox" || nodeToCopy.checked) {
var hiddenField = document.createElement('input');
hiddenField.type = "hidden";
hiddenField.name = nodeToCopy.name;
hiddenField.value = nodeToCopy.value;
to.appendChild(hiddenField);
elementsAdded.push(hiddenField);
}
}
return elementsAdded;
}
var addedFields = [];
document.getElementById('myForm').addEventListener('submit', function() {
// Remove any fields that were previously added
for (var i = 0; i < addedFields.length; i++) {
this.removeChild(addedFields[i]);
}
// Add the new hidden fields
var copyFrom = document.getElementById('otherform');
addedFields = copyFormFieldsIntoHiddenFields(copyFrom, this);
});
</script>

HtmlService form submit opens new tab with foo bar URL

I am attempting to build a UI for a spreadsheet using GAS HtmlService. The HTML below is a very simple form with a single text box that pulls a value ("Kristina") from the sheet, successfully. However, when I try to submit the form a new tab is opened in Chrome that attempts to open the URL "bffc95ee-ff64-4d2c-xxxx-19d9824eb4b4.foo.bar/?fname=Kristina" with "xxxx" replacing more random letters and numbers (just in case). At no point do I use the words "foo.bar" in my code, so I'm pretty sure that that part isn't coming from me. It does not change each time or after logging out and back in. I'm getting the same result on two different computers.
<html>
<body>
<div>
<form id="formtest1">
<label>First Name</label>
<input name="fname" type="text" maxlength="255" value="<?= fname ?>"/>
<input type="submit" value="Submit"
onclick="google.script.run.processForm(document.getElementById('formtest1'));
google.script.host.close()"/>
</form>
</div>
</body>
</html>
The above is being displayed using the following function:
function htmltest(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sht = ss.getActiveSheet();
var html = HtmlService.createTemplateFromFile("HTML");
html.fname = sht.getRange(2, 3).getValue();
ss.show(html.evaluate());
};
If I understand correctly, the "google.script.run.processForm(...)" script in the HTML should trigger the following function, as set up in the projects triggers:
function onFormSubmit(){
Browser.msgBox("Test");
};
But it doesn't appear to do so as the form doesn't close and the msgBox doesn't appear. Only the foo bar URL in a new tab.
Hopefully I've explained the issue clearly and am not making an embarrassing mistake.
You cannot use a real "submit" button with google.script.run (this is a documented restriction in the user guide). Change it to "button" and it should work fine.
The project trigger onFormSubmit() will be triggered by a submission via the Forms Service. There is no relationship between this trigger and your HTML code; they are two different ways to interact with users.
An html forms pattern is shown in the HTML Service documentation here, and the script below is an adaptation of it.
Code.gs
The only real change from your original is that onFormSubmit() has been replaced with processForm(form), which includes a parameter, for the object that will be passed from the html code.
function onOpen() {
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var entries = [{
name : "htmltest",
functionName : "htmltest"
}];
sheet.addMenu("Custom Menu", entries);
};
function htmltest(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sht = ss.getActiveSheet();
var html = HtmlService.createTemplateFromFile("HTML");
html.fname = sht.getRange(2, 3).getValue();
//Logger.log( html.getCodeWithComments() );
ss.show(html.evaluate());
};
function processForm(form){
var fname = form.fname;
Browser.msgBox("Test - " + fname);
};
HTML.html
This is a modification of your original, echoing the pattern from the documentation. The form submission SuccessHandler is a one-liner, which closes the dialog. Once it completes, the server-side function is invoked with the form content, retrieved using this.parentNode (to refer to the form).
There are other ways - see Get value of html text box in Apps Script function for a different approach.
<html>
<script type="text/javascript">
// SuccessHandler to close form
function close() {google.script.host.close();}
</script>
<body>
<div>
<form>
<label>First Name</label>
<input name="fname" type="text" maxlength="255" value="<?= fname ?>"/>
<input type="button" value="Submit" onclick="google.script.run
.withSuccessHandler(close)
.processForm(this.parentNode)"/>
</form>
</div>
</body>
</html>
Just add this to your script tag on your html file.
// Prevent forms from submitting.
function preventFormSubmit() {
var forms = document.querySelectorAll('form');
for (var i = 0; i < forms.length; i++) {
forms[i].addEventListener('submit', function(event) {
event.preventDefault();
});
}
}
window.addEventListener('load', preventFormSubmit);

How can I assign different actions for different submit buttons in same html form?

I am trying to assign different actions to same html form according to different submit buttons.
Can I do something like this ?
<FORM>
------
<INPUT type="submit" value="DoSomething" action="DoSomething.pl" method="POST">
<INPUT type="submit" value="DoSomethingElse" action="DoSomethingElse.pl" method="POST">
<FORM/>
Just in case someone else finds this post:
If you're using HTML5, this is now easier thanks to the formaction attribute. This attribute applies to input and button elements of type="submit" and forces the form to submit to the location specified in the formaction attribute of the clicked element.
Then only drawback of this attribute is that it's not supported by Internet Explorer 9 and lower, but this limitation can be easily overcome using a little JavaScript.
Example:
<form method="post" action="go_default">
<input type="submit" value="Go Left" formaction="go_left" />
<input type="submit" value="Go Right" formaction="go_right" />
</form>
For IE 9 and lower:
<script type="text/javascript">
$(function () {
var $submit = $('form [type="submit"][formaction]');
$submit.click(function() {
var $this = $(this),
action = $this.prop('formaction'),
$form = $this.closest('form');
$form.prop('action', action).submit();
});
});
</script>
No. A form has only one action (action being a property of the form, not the submit button).
The target of the action can do different things on the basis of the values in the form. So, you might want to start naming your submit buttons.
Learn HTML before you even think about writing and deploying a CGI script.
<form method="POST" action="/cgi-bin/script">
<input type="submit" name="action" value="DoSomething">
<input type="submit" name="action" value="DoSomethingElse">
</form>
Note also that choosing an action based on the value of the submit button is a losing strategy if you wish to internationalize the application because the value of a submit button is what the UA displays to humans.
Therefore, script should decide what to do on the basis of some other input element's value.
For example, CGI::Application looks at a run_mode parameter.
Alternatively, you can use different names for your submit buttons as Alec suggests. In that case, you need to check which submit button was pressed by going through the names of the parameters passed to your script which, IMHO, makes the dispatch slightly more cumbersome. It also means it is possible for someone to pass values for all submit buttons to your script (not via the user interface, but via curl or wget or similar programs.
For example, given the HTML
<form method="POST" action="/cgi-bin/script">
<input type="submit" name="submit_left" value="Go Left">
<input type="submit" name="submit_right" value="Go Right">
</form>
here is how your script may handle form submission:
#!/usr/bin/perl
use strict; use warnings;
use CGI::Simple;
my $cgi = CGI::Simple->new;
my %dispatch = (
left => \&handle_left,
right => \&handle_right,
);
my #actions = grep s/^action_(right|left)\z/$1/, $cgi->param;
my $handler = \&handle_invalid_action;
if ( #actions == 1) {
my ($action) = #actions;
if ( exists $dispatch{ $action } ) {
$handler = $dispatch{ $action };
}
}
else {
$handler = \&handle_too_many_actions;
}
$handler->($cgi);
sub handle_left { }
sub handle_right { }
sub handle_invalid_action { }
# because it may indicate someone trying to abuse your script
sub handle_too_many_actions { }
You can also use Ajax for this, and every button has assigned an ajax function that calls it's own php script and you don't even need to refresh the page or redirect, like in this example that i have tried:
HTML:
<input type="submit" value="Make other thing" onclick="ajax_post1();"/>
<input type="submit" value="Make something" onclick="ajax_post2();"/>
<div id="script1Response"></div>
<div id="script2Response"></div>
Javascript functions:
//the first function
function ajax_post1(){
var hr = new XMLHttpRequest();
//take the values from the html input elements you want to use
var v1=document.getElementbyId("element1").value;
var v2=document.getElementbyId("element2").value;
//the script that will process the data
var url="php_script1.php";
//the variable that will contain the information for the php script
var dataVar="var1="+v1+"&var2="+v2;
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
// Access the onreadystatechange event for the XMLHttpRequest object
hr.onreadystatechange = function() {
if(hr.readyState == 4 && hr.status == 200) {
var script_response = hr.responseText;
document.getElementById("script1Response").innerHTML = script_response;
}
}
// Send the data to php_script1.php
hr.send(dataVar); // Actually execute the request
document.getElementById("script1Response").innerHTML = "processing...";
}
//the second function
function ajax_post2(){
var v1=document.getElementbyId("element1").value;
var v2=document.getElementbyId("element2").value;
var url="php_script2.php";
var dataVar="var1="+v1+"&var2="+v2;
var hr = new XMLHttpRequest();
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
hr.onreadystatechange = function() {
if(hr.readyState == 4 && hr.status == 200) {
var script_response = hr.responseText;
document.getElementById("script2Response").innerHTML = script_response;
}
}
hr.send(dataVar);
document.getElementById("script2Response").innerHTML = "processing...";
}
The php files will have to contain some variables that will store the values sent by dataVar parameter like this:
$var1_=$_POST['var1']; //the var1 from the dataVar parameter
$var2_=$_POST['var2']; //the var2 from the dataVar parameter
The example I used can be found here:
