i'm not a very good programmer at all but i need a little help with a webpage i'm making.
Here's what I have for a form:
<form name="input" action="name.htm" method="get">
Name: <input type="text" name="name">
<input type="submit" value="Submit">
</form>
What I want it to do is if I put in the name Fred and press submit Button, it will go to a certain page. Any other name will link to another page or popup with an error saying, "tough luck!" or something like that.
Sorry, I couldn't find anything this specific on the web anywhere. I'm sure it's simple, I'm just confused with how this works. Thank you!
using front-end only, i'd be using javascript or jquery. meaning you don't need a form element inside it.
<script>
$("#submitButton").click(function(){
window.location.replace("enter url here")
})
</script>
you can do it with JS/jQuery:
HTML
<form name="input" action="name.htm" method="get">
Name: <input type="text" name="name" id="name">
<input type="submit" id="submit-button" value="Submit">
</form>
JS
$("#submit-button").click(function(){
if ($("#name").val() == "Fred")
location.href = "goodurl";
else
location.href = "badurl";
});
There are 2 options to solve this problem.
To use JavaScript for input value's validation and depending on it to redirect user
To use server side language to check the passed value
The first option will be easier for you I guess.
You can do something like:
Name: <input type="text" name="name">
<input type="button" value="Submit" onClick="redirect();">
<script type="text/javascript">
function redirect() {
var value = document.getElementsByName('name')[0].value;
if (value == 'Fred') {
window.location.href='http://url1';
} else {
window.location.href='http://url2';
}
}
</script>
Links: 'url1' and 'url2' must be replaced with your URLs
Just add the following code in your HTML file and try it out:
<script type="text/javascript">
function handleSubmit() {
var name = document.input.name.value;
if(name == 'Fred') {
location.href = "http://www.google.com";
} else if (name == 'Jack') {
location.href = "http://www.yahoo.com";
} else {
alert("Tough Luck");
}
}
</script>
<form name="input" action="name.htm" method="get">
Name: <input type="text" name="name">
<input type="button" value="Submit" onclick="handleSubmit();">
</form>

I have this code that needs to be adapted to work with something similar to the code below the commented line. If I can make it without many changes would be perfect so that I don't need to change the CSS and so. Any help? Many thanks in advance.
<!-- The code to be adapted is this: -->
<form action="" id="search-form">
<fieldset>
<input type="text" class="text" /><input type="submit" value="Search" class="submit" />
</fieldset>
</form>
<!-- The new code that I got from the web and that needs to be adapted to the old one
is the following: -->
<textarea id="Blah"></textarea><button onclick="search()">Search</button>
<script>
function search() {
var Blah = document.getElementById("Blah").value;
location.replace("https://www.google.com/search?q=" + Blah + "");
}
</script>
I'm imagining you probably want something like
document.querySelector("#searchButton").addEventListener("click", ()=>{
const value = document.querySelector("#searchBox").value;
const url = `https://www.google.com/search?q=${encodeURIComponent(value)}`;
window.location.replace(url);
});
<fieldset>
<input type="text" class="search" id="searchBox">
<Button id="searchButton">Search</button>
</fieldset>
The id attribute on HTML elements allows you to access them via JavaScript. There's a wealth of tutorials online if you want to learn JavaScript deeply, but the basics of what this is doing is:
It finds the HTML element with the id of searchButton, and adds a click listener to it --- this gets triggered whenever that element is clicked.
In that listener, we find the value of the text input with the id of searchBox.
We compose our new URL. One thing I've added here is a call to encodeURIComponent to correctly handle the cases where they try searching for something which contains a character which isn't valid in a URL --- for example, the space character etc.
It was not working as I wanted, but a little trick made it work.
Here is my final code:
<form action="" id="search-form">
<fieldset>
<input type="text" class="search" id="searchBox">
<input type="submit" value="Search" class="submit" />
</fieldset>
</form>
<script>
let myvar;
document.querySelector(".submit").addEventListener("click", ()=>{
const value = document.querySelector("#searchBox").value;
myvar = `https://www.google.com/search?q=${encodeURIComponent(value)}`;
setTimeout(callurl, 1);
return false;
});
function callurl() {
location.assign(myvar);
return false;
}
</script>
Making a little search engine. The idea is to take input from the user and then based on that, make a redirection to the search page.
The following code:
<form action ="/search.html">
<label for="form-search"></label>
<input type="text" id="form-search" placeholder="TYPE HERE!"><hr>
<input type="submit" name="query" value="Search!">
</form>
Always redirects to the following page regardless of what the input user has given:
/search.html?query=++Search%21++
While (for the input "Suppose This Was Entered") it should go to:
/search.html?query=Suppose++This++Was++Entered
Any help will be appreciated.
The var name used in the query string of the url is the name attribute of the form fields so you need add a name atribute to your text field instead to the submit input.
<form action ="/search.html">
<label for="query"></label>
<input type="text" id="query" name="query" placeholder="TYPE HERE!"><hr>
<input type="submit" value="Search!">
</form>
The id and the name in the text field not necessary has to be the same
You can create a function that gets called when the form submits via the form's onsubmit attribute. From within the funciton you can manipulate your URL generation like below:
Note: return false; is to prevent submitting the form since the return value of the function is passed to the form's onsubmit.
function submitFunction() {
let searchText = document.getElementById("form-search").value.trim();
let form = document.getElementById('myForm');
if(searchText.length > 0) {
document.getElementById("s").value = searchText;
form.action = "/search.html";
form.submit();
} else {
return false;
}
}
<!DOCTYPE html>
<html>
<head>
<title>Title of Your page</title>
</head>
<body>
<form id="myForm" method="get" onsubmit="return submitFunction();">
<label for="form-search"></label>
<input type="text" id="form-search" placeholder="TYPE HERE!" value="" >
<input type="hidden" id="s" name="query" value="" />
<hr>
<input type="submit" value="Search!">
</form>
</body>
</html>
I'm fairly new to coding in HTML. After hours of searching the internet for a way to do this, I failed and so I'm here. I was setting up a CSRF Proof of concept page here, I want it to redirect to another page which will execute the payload that the CSRF had implemented.
<html>
<body>
<form action="https://website.com/action.php?" method="POST">
<input type="hidden" name="fullname" value="john" />
<input type="hidden" name="address" value="street 2, 32 ave" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
So after this form is submitted using, all it does is redirect to this page
But instead of that, I want it to redirect to another URL as well as submit that form.
For anyone else having the same problem, I figured it out myself.
<html>
<body>
<form target="_blank" action="https://website.com/action.php" method="POST">
<input type="hidden" name="fullname" value="Sam" />
<input type="hidden" name="city" value="Dubai " />
<input onclick="window.location.href = 'https://website.com/my-account';" type="submit" value="Submit request" />
</form>
</body>
</html>
All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.
You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.
Example:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
window.location.href = 'https://website.com/my-account';
}
};
xhttp.open("POST", "demo_post.asp", true);
xhttp.send();
in case you are generating the form programmatically you can add this script at the end of the form
<script type="text/javascript">document.forms["FormId"].submit();</script>
What you could do is, a validation of the values, for example:
if the value of the input of fullanme is greater than some value length and if the value of the input of address is greater than some value length then redirect to a new page, otherwise shows an error for the input.
// We access to the inputs by their id's
let fullname = document.getElementById("fullname");
let address = document.getElementById("address");
// Error messages
let errorElement = document.getElementById("name_error");
let errorElementAddress = document.getElementById("address_error");
// Form
let contactForm = document.getElementById("form");
// Event listener
contactForm.addEventListener("submit", function (e) {
let messageName = [];
let messageAddress = [];
if (fullname.value === "" || fullname.value === null) {
messageName.push("* This field is required");
}
if (address.value === "" || address.value === null) {
messageAddress.push("* This field is required");
}
// Statement to shows the errors
if (messageName.length || messageAddress.length > 0) {
e.preventDefault();
errorElement.innerText = messageName;
errorElementAddress.innerText = messageAddress;
}
// if the values length is filled and it's greater than 2 then redirect to this page
if (
(fullname.value.length > 2,
address.value.length > 2)
) {
e.preventDefault();
window.location.assign("https://www.google.com");
}
});
.error {
color: #000;
}
.input-container {
display: flex;
flex-direction: column;
margin: 1rem auto;
}
<html>
<body>
<form id="form" method="POST">
<div class="input-container">
<label>Full name:</label>
<input type="text" id="fullname" name="fullname">
<div class="error" id="name_error"></div>
</div>
<div class="input-container">
<label>Address:</label>
<input type="text" id="address" name="address">
<div class="error" id="address_error"></div>
</div>
<button type="submit" id="submit_button" value="Submit request" >Submit</button>
</form>
</body>
</html>
For me this one worked pretty well.
=> form target to blank (opens in a new tab) + input id to be recognized in Javascript + script that redirects.
<html>
<body>
<form target="_blank" action="https://website.com/action.php" method="POST">
<input type="hidden" name="fullname" value="Sam" />
<input type="hidden" name="city" value="Dubai " />
<input type="submit" value="Submit request" id="submitBtn"/>
<script>
document.getElementById("submitBtn").addEventListener("click", myFunction);
function myFunction() {
window.location.href="http://programminghead.com";
}
</script>
</form>
</body>
</html>
I found it here: https://programminghead.com/submit-button-redirect-to-another-page-in-html
I am trying to get this get form to take me to a URL based on the users input (search keyword).
<form method="get" action="https://rally1.rallydev.com/#/search" target="_blank">
<input type="text" name="keywords" size="25" maxlength="255" value="US111111">
<input type="submit" value="Search"/>
In this case, the Value (US111111) is set by default but this is user editable.
When the above query is executed, the following URL should be opened
https://rally1.rallydev.com/#/search?keywords=US111111
However, instead
https://rally1.rallydev.com/?keywords=US144771#/search
Is opened.
I think I see why this is happening, the # seems to indicate the root path.
What am I doing wrong?
Thanks
I worked it out, but had to use js.
in the html page I used:
<input type="text" name="q" id="q" autofocus>
<input type="button" id="s" value="Search">
and in the js:
$(function() {
$('#s').click(function() {
var url = "https://rally1.rallydev.com/#/3961662024ud/search?keywords=" + $('#q').val();
chrome.tabs.create({url: url});
});
$('#q').keypress(function(e) {
if (e.keyCode == '13') {
e.preventDefault();//Stops the default action for the key pressed
var url = "https://rally1.rallydev.com/#/3961662024ud/search?keywords=" + $('#q').val();
chrome.tabs.create({url: url});
return false;//extra caution, may not be necessary
}
});
});
document.addEventListener('DOMContentLoaded');
Hope this helps someone else.
I have created a basic HTML contact form using cgimail and everything works, but I can't get it to keep from redirecting somewhere after the form is submitted. I'm trying to instead use a bootstrap alert at the top of the page.
How do I get the form to submit, then keep it from redirecting?
here's the code:
<form method="post" action="/cgi-bin/cgiemail/forms/email.txt">
<fieldset>
<h2 id="contact-header">Contact</h2>
<label>Name:</label>
<input type="text" name="yourname" placeholder="" autofocus>
<label>Email Address:</label>
<input type="email" name="email" value="" placeholder="">
<label>Phone:</label>
<input type="tel" name="phone" value="" placeholder="">
<label>Message:</label>
<textarea name="message" rows="2"></textarea>
<br>
<button type="submit" id="formSubmit" class="btn">Send</button>
<input type="hidden" name="success" value="">
</fieldset>
</form>
Thanks,
Ryan
The "action" attribute in your form is telling it to send the browser over to that email.txt, which would then have control over whether or not to redirect you to another page. By default it would at least redirect you to the email.txt page for the post, but odds are cgi is doing extra stuff when posting to that page.
Using jQuery AJAX, you can do the following (this code skips error checking):
$('form').submit(function() {
var data = { };
data.yourname = $(this).find('input[name="yourname"]').val();
data.message = $(this).find('textarea[name="message"]').val();
// do the same as above for each form field.
$.post("/cgi-bin/cgiemail/forms/email.txt", data, function() {
//add the alert to the form.
$('body').prepend('div class="alert">Success!</div>');
});
return false;
});
You have two straight-forward choices. You can use jQuery and its forms plugin to turn this into an ajax operation or you can roll your own equivalent. It would look something like this (using jQuery):
$('form').submit(function() {
... get all values.
... ajax post the values to the server.
return false;
});
If you're using jQuery, then you could try cancelling the submit event. First give your form an id
HTML:
<form id="myform" ...
JavaScript:
$('#myform').on('submit', function(e) {
e.preventDefault();
$.ajax({
url: '/cgi-bin/cgiemail/forms/email.txt',
type: 'post',
data: $(this).serialize()
});
return false;
});
