I have a preference set in adfmf-feature and in amx page I get it using <amx:inputText label="url" id="it1" value="#{preferenceScope.feature.adf.mobile.sample.ProfilePage.showProfileImage.showImage}"/>.
But if i use the same format for HTML <input type="username" name="xyz" id="user" value= "#{preferenceScope.feature.adf.mobile.sample.username}" /> i am not able to get the result.
i get #{preferenceScope.feature.adf.mobile.sample.username} itself as the output in the text box!
The values here are just for identification purpose. They match the their respective id's in my application
Should it be written in Javascript side? or is there any other way to get the value and set?
Thank you
in order to get the preference value and insert it into a field in an HTML page you need to use the javascript api adf.mf.el.getValue(expresion, onSuccess, onFail)
so in your case you can do the below
<script type="text/javascript">
function getPrefVal(){
adf.mf.el.getValue("#{preferenceScope.feature.adf.mobile.sample.ProfilePage.showProfileImage.showImage}",
onSucess,onFail);
}
function onSucess(req, res) {
//alert( res[0]['value']);
$("#user").val(res[0]['value']);
}
function onFail (req, res) {
alert("Get Value Failed :" + adf.mf.util.stringify(res));
}
//use the below code instead of $(document).ready() or deviceready
document.addEventListener("showpagecomplete", getPrefVal, false);
</script>
<input type="username" name="xyz" id="user" value= "" />
HTML doesn't know how to resolve an EL expression - see if you have a Javascript API that lets you access the preferences.

Good morning all:
Looks like a very common question, but after googling for hours I am not able to figure this out: how to validate an URL including www without http.
These is what I did:
Used the input type url: it does not accept www.google.com;
Changed the input type to text and used ng-pattern: I still get the www.google.com invalid;
Changed different regex but still not working.
So when I click on the submit button, I show an alert if the form is invalid (true invalid, false valid). Here is my Plunker
Thanks for the help
Instead of binding the regex to scope, you could directly add the regex to ng-pattern attribute. Like this:
<input type="text" ng-pattern="/^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/" ng-model="website">
I have updated the plunkr. Please take a look at this. Plukr
The thing here is, if you want to bind ng-pattern from controller, your regex shouldn't contain the starting and ending /s. Like this:
$scope.regex = "^(http[s]?:\\/\\/){0,1}(www\\.){0,1}[a-zA-Z0-9\\.\\-]+\\.[a-zA-Z]{2,5}[\\.]{0,1}$"
But, if you directly specify pattern like ng-pattern="/^(http|https|...)$/", you need the extra /s as well.

Try using the ng2-validation library. It can be used to perform most validations you should ever need. Angular2 custom validation, inspired by jQuery validation.
I think we can also use AngularJs builtin URL validator.
<script>
angular.module('urlExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.url = {
text: 'http://google.com'
};
}]);
</script>
<form name="myForm" ng-controller="ExampleController">
<label>URL:
<input type="url" name="input" ng-model="url.text" required>
<label>
<div role="alert">
<span class="error" ng-show="myForm.input.$error.required">
Required!</span>
<span class="error" ng-show="myForm.input.$error.url">
Not valid url!</span>
</div>
<tt>text = {{url.text}}</tt><br/>
<tt>myForm.input.$valid = {{myForm.input.$valid}}</tt><br/>
<tt>myForm.input.$error = {{myForm.input.$error}}</tt><br/>
<tt>myForm.$valid = {{myForm.$valid}}</tt><br/>
<tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br/>
<tt>myForm.$error.url = {{!!myForm.$error.url}}</tt><br/>
</form>
`
if (this.resource.url.match("^(https:\/\/|http:\/\/)")) {
if (this.resource.url.match("^(https:\/\/www\.|http:\/\/www\.)?([da-z.-]+)\\.([a-z.]{2,6})")) {
}
else
{
errorMessages.push("url is invalid");
}
}
else {
errorMessages.push("url is invalid");
}
`
I'm working on a project that I need from login, to compare the information at the form with the database. And later, after doing the validation, I need to load the information of a login in another page (I have no idea how).
(I tried to find some tutorials, but all of them use Express, that I'm not allowed to)
Now my code:
HTML (I think this part is OK, cause I could save the information in $scope.u)
<form ng-controller = "login" ng-submit="submit(user)">
<label>Login:</label>
<input type="text" ng-model="user.login" required>
<label>Senha:</label>
<input type="password" ng-model="user.pwd" required>
<label><input type="checkbox"> Lembre-me</label>
<button type="submit" class="btn btn-default">Login</button>
<p>{{user.login}}</p>
<p>{{user.pwd}}</p>
<p>LOGIN:{{user.login}}</p>
<p>SENHA:{{user.pwd}}</p>
</form>
Angular (I'm not sure if I understood the idea of $http.post, so I don't know if I can send the info of $scope.u to Nodejs)
app.controller('login',function($scope,$http){
$scope.u = {};
$scope.submit = function(user) {
$scope.u = angular.copy(user);
console.log($scope.u);
};
$http.post('/servico/login', $scope.u).success(function(data, status) {
console.log('Data posted successfully');
});
});
Node (If I could use the information of $scope.u, my problem would be finished there, but I don't know how I can load the information in another page)
The button Login should compare the values from the form and them, maybe, use to send to the other page.
function login(request,response){
var queryString = 'SELECT uLogin,uSenha FROM usuarios';
connection.query(queryString,function(err,rows){
});
}
I hope I've been clear with my doubt.
Thanks for your help.
Stage
Suppose an HTML page in some URL (i.e. http://mysite.com/registry.html) and this HTML file contains a HTML form, like this:
<form action="/">
<input name="firstname">
<input name="lastname">
<textarea name="message"></textarea>
</form>
If I want to prefill this form how can I do this?
Maybe I thought that I can prefill this form on URL request. But I do not know if it is possible.
Restriction
I do not have access to mysite.com server nor registry.html.
Maybe with some JavaScript sorcery, load the page (http://example.com/registry.html) via AJAX:
function loadPage()
{
jQuery.ajax({
type: "GET",
url: "http://example.com/registry.html",
success: successFn
});
}
function successFn(data)
{
var result=jQuery(data).find("#idOfTheInput").html()
//modify the default value
//re attach the input into the html
//render the html
}
The rest is up to you; dig into the dom and put the values you want.
You can try to pass parameters by the url.
Something like this:
http://test.com?param1
This url is passing a parameter (param1), so you can set up the members of this form to be able to receive these parameters.

I'm making a form where the user can enter a dollar amount using an html number input tag. Is there a way to have the input box always display 2 decimal places?
So if someone else stumbles upon this here is a JavaScript solution to this problem:
Step 1: Hook your HTML number input box to an onchange event
myHTMLNumberInput.onchange = setTwoNumberDecimal;
or in the html code if you so prefer
<input type="number" onchange="setTwoNumberDecimal" min="0" max="10" step="0.25" value="0.00" />
Step 2: Write the setTwoDecimalPlace method
function setTwoNumberDecimal(event) {
this.value = parseFloat(this.value).toFixed(2);
}
By changing the '2' in toFixed you can get more or less decimal places if you so prefer.
an inline solution combines Groot and Ivaylo suggestions in the format below:
onchange="(function(el){el.value=parseFloat(el.value).toFixed(2);})(this)"
An even simpler solution would be this (IF you are targeting ALL number inputs in a particular form):
//limit number input decimal places to two
$(':input[type="number"]').change(function(){
this.value = parseFloat(this.value).toFixed(2);
});
What other folks posted here mainly worked, but using onchange doesn't work when I change the number using arrows in the same direction more than once. What did work was oninput. My code (mainly borrowing from MC9000):
HTML
<input class="form-control" oninput="setTwoNumberDecimal(this)" step="0.01" value="0.00" type="number" name="item[amount]" id="item_amount">
JS
function setTwoNumberDecimal(el) {
el.value = parseFloat(el.value).toFixed(2);
};
The accepted solution here is incorrect.
Try this in the HTML:
onchange="setTwoNumberDecimal(this)"
and the function to look like:
function setTwoNumberDecimal(el) {
el.value = parseFloat(el.value).toFixed(2);
};
Pure html is not able to do what you want. My suggestion would be to write a simple javascript function to do the roudning for you.
You can use Telerik's numerictextbox for a lot of functionality:
<input id="account_rate" data-role="numerictextbox" data-format="#.00" data-min="0.01" data-max="100" data-decimals="2" data-spinners="false" data-bind="value: account_rate_value" onchange="APP.models.rates.buttons_state(true);" />
The core code is free to download
I used #carpetofgreenness's answer in which you listen for input event instead of change as in the accepted one, but discovered that in any case deleting characters isn't handled properly.
Let's say we've got an input with the value of "0.25". The user hits "Backspace", the value turns into "0.20", and it appears impossible to delete any more characters, because "0" is always added at the end by the function.
To take care of that, I added a guard clause for when the user deletes a character:
if (e.inputType == "deleteContentBackward") {
return;
}
This fixes the bug, but there's still one extra thing to cover - now when the user hits "Backspace" the value "0.25" changes to "0.2", but we still need the two digits to be present in the input when we leave it. To do that we can listen for the blur event and attach the same callback to it.
I ended up with this solution:
const setTwoNumberDecimal = (el) => {
el.value = parseFloat(el.value).toFixed(2);
};
const handleInput = (e) => {
if (e.inputType == "deleteContentBackward") {
return;
}
setTwoNumberDecimal(e.target);
};
const handleBlur = (e) => {
if (e.target.value !== "") {
setTwoNumberDecimal(e.target);
}
};
myHTMLNumberInput.addEventListener("input", handleInput);
myHTMLNumberInput.addEventListener("blur", handleBlur);
Look into toFixed for Javascript numbers. You could write an onChange function for your number field that calls toFixed on the input and sets the new value.
What I didn't like about all these solutions, is that they only work when a form is submitted or input field is blurred. I wanted Javascript to just prevent me from even typing more than two decimal places.
I've found the perfect solution for this:
<!DOCTYPE html>
<html>
<head>
<script>
var validate = function(e) {
var t = e.value;
e.value = (t.indexOf(".") >= 0) ? (t.substr(0, t.indexOf(".")) + t.substr(t.indexOf("."), 3)) : t;
}
</script>
</head>
<body>
<p> Enter the number</p>
<input type="text" id="resultText" oninput="validate(this)" />
</body>

I am trying to use the form method checkValidity().
http://html5test.com/ tells me that my browser (Chrome) support the form-level checkValidity method.
However, using jsfiddle http://jsfiddle.net/LcgnQ/2/ I have tried the following html and javascript snippets:
<form id="profileform" name="profileform">
<input type="text" id="firstname" required>
<input type="button" id="testbutton" value="Test">
</form>
$('#testbutton').bind('click',function(){
try{
alert($('#profileform').checkValidity());
}
catch(err){alert('err='+err)};
});
I'm getting an error: object has no method checkValidity()
What am I doing wrong?
Try:
$('#profileform')[0].checkValidity()
When you select $('#profileform') you get a jQuery object array. To access actual DOM properties you must select the first item in the array, which is the raw DOM element.
#robertc 's Answer is perfect. Anyway I'd just add another way to do it using jQuery's .get([index]) function. It also retrieves the DOM element for the given index, or all of the matched DOM elements if there's no index declared.
In the end it is exactly the same, only written in a bit more verbose way:
$('#profileform').get(0).checkValidity()
Leaving you the docs right here: https://api.jquery.com/get/
Just another way:
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.getElementsByName('profileform');
// Loop over them and prevent submission
var validation = Array.prototype.filter.call(forms, function (form) {
form.addEventListener('submit', function (event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
}, false);
});
