I have html form and want to make a validation by submitting the form with its specific id and validate it using jquery.
Here is my code:
HTML
<html>
<head>
<script src="jquery-1.11.2.min" type="text/javascript"></script>
</head>
<body>
<form method="post" name="frmhot" id="contactform3412">
<input type="text" name="status"/>
<input type="text" name="line"/>
<input type="text" name="reason"/>
<input type="text" name="partnum"/>
<input type="text" name="badgescan"/>
<input class="button_text" type="submit" value="Submit"/>
</form>
<script type="text/javascript">
var url = "";
jQuery("#contactform3412").submit(function(e){
url= 'works well!';
});
alert(url);
</script>
</body>
For this example, i want to get the value of the javascript variable 'url' within the jQuery condition submit. Thanks in advance :)
Use this -> Fiddle
var url = "";
$("#contactform3412").submit(function(e){
url= 'works well!';
alert(url);
return true;
});
Anyways you set url value and perform operations after submit,so use url value there only. In your problem, url could not set to "works well" as submit event was not fired.
You're missing the js file extension in your script declaration. It should be
<script src="jquery-1.11.2.min.js" type="text/javascript"></script>
instead of
<script src="jquery-1.11.2.min" type="text/javascript"></script>
With that, if you wrap your submit handler in document.ready(), it should work on click of form submit.
$(document).ready(function(){
var url = '';
$('#contactform3412').on('submit', function(e){
e.preventDefault();
url= 'works well!';
alert(url);
});
});

I have page with form on it, I am trying to disable the button on submit with a custom disable message on it, and submit the form after using jquery.
<form>
<input type="text" name="run"/>
<input type="submit" class="send" value="Save" data-attr-message="Sending..."/>
</form>
I have try both form submit or form[0] submit neither submits the form, I try logging the form, the form is logged correctly to console, and there are no errors in console when clicking submit.
$(document).ready(function() {
$('.send').click(function(e) {
e.preventDefault();
e.stopPropagation();
var button = $(this);
var form = button.closest("form");
button.prop('disabled', true);
button.val($(this).attr('data-attr-message'));
console.log(form); //Logs form fine
form[0].submit();
// form.submit();
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form>
<input type="text" name="run" />
<input type="submit" class="send" value="Save" data-attr-message="Sending..." />
</form>
Your form does not have an "action" and "method".
It should look like:
<form action = "http://example.com/backendScript" method = "POST">
if your goal is to "simulate" the time that it takes to send data, and you want to see the button to be disabled until that time, one way is to use "setTimeout()" method of javascript. you do not need to use "e.preventDefault()" because it prevent the form from submitting. I posted the code below that I think does what you expected:
$(document).ready(function() {
$('.send').click(function(e) {
var button = $(this);
var form = button.closest("form");
button.prop('disabled', true);
button.val($(this).attr('data-attr-message'));
setTimeout(function() {
form.submit();
}, 1000)
});
});

the "submit.html" is simply an html file with a message that you can add to your folder yourself to see that the form is submitting.
What i'm missing here to print 'user_input' to display paragraph ?
is myform.submit required? Because actually I can access the variable and make an alert with it..
<script language="JavaScript">
function getData(input) {
var input = document.getElementById("user_input").value;
// alert(input)
document.myform.submit()
$('.display').text("The URL is : " + input)
}
</script>

integrity="sha256-tA8y0XqiwnpwmOIl3SGAcFl2RvxHjA8qp0+1uCGmRmg="

<form id="myform">
<label><b>Enter a URL</b></label>
<input type="text" name="message" id="user_input">
<input type="submit" id="submit" onclick="getData()"><br/>
<p id="display"><span></span></p>
</form>
Don't mix java-script/jQuery into each-other.
Since you are using jQuery library then do it in a better way like below:-
Working example:-
$(document).ready(function(){ // when document is rendered completely
$('#submit').click(function(e){ // on click of submit button
e.preventDefault(); // prevent the form submit
var input =$("#user_input").val(); // get input value
$('#display').text("The URL is : " + input); // add it as a text to paragraph
});
});
<script src="https://code.jquery.com/jquery-3.2.1.slim.js" integrity="sha256-tA8y0XqiwnpwmOIl3SGAcFl2RvxHjA8qp0+1uCGmRmg=" crossorigin="anonymous"></script>
<form id="myform">
<label><b>Enter a URL</b></label>
<input type="text" name="message" id="user_input">
<input type="submit" id="submit"><br/><!-- no need of onclick-->
<p id="display"><span></span></p>
</form>
You must do what the response is actually asking you to do which simply is adding the method attribute to the form element: <form method="POST">
Working DEMO
I'm trying to validate a password from a form using jQuery/JavaScript. Post-validation, I want the script to redirect me. However, this isn't currently working.
Note: this is only an exercise from my university, so that's why the code is very simple:
HTML:
!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="js/jquery-2.1.3.min.js"></script>
<script type="text/javascript" src="js/passwordCheck.js"></script>
</head>
<body>
<form method="post" name="form1" id="form-password" action="">
<label>Password:</label>
<input type="password" name="password" id="password" value="" size="32" />
<input type="submit" value="Continue" id="submit">
</form>
</body>
</html>
JS/jQuery:
'use strict';
jQuery(document).ready(function($) {
$('#form-password').submit(function() {
var passwordVal = $('#password').val();
if (passwordVal === "123" ) {
$(location).attr('href', 'http://www.stackoverflow.com');
}
});
});
I tried:
window.location.href = "http://www.stackoverflow.com";
but that doesn't work either.
I know that I need to check the submitted data, my problem is only with redirection.
How can I fix this?
You simply need to preventDefault() inside your submit listener, and then call
window.location.href = "...";
Currently, without preventing the default action of submitting a form, the form tries to POST your data, regardless of what happens in the submit callback.
If you preventDefault, the form will not submit until you return true.
That being said, redirects should be performed on the backend or by the front-end MVC framework. In any way, the password data needs to be submitted and checked against a database somewhere.
Try this, you are modifying the window.location.href property, you really want to be setting the window.location like this:
$('#form-password').submit(function(e) {
e.preventDefault();
var passwordVal = $('#password').val();
if (passwordVal === '123') {
window.location = 'http://www.stackoverflow.com';
}
});
i am trying to write a simple textbox (for people to type url in it) with a button in html.
when the button is clicked, it will send the url of the current website that I am browsing to the url that is listed in the textbox using the POST method. is it possible?
i have been looking on forums but don't really know which is the right one cos it seems that there are various way of doing it and i don't really know how to edit them.
my current code:
<html>
<head>
<title>YouTube</title>
<script type="javascript/text">
function handleButtonEnterClick(tab) {
//TODO:
var textbox_url = document.getElementById("url_textbox");
var textbox_value = textbox_url.value; //eg. value = "www.google.com"
//Need to have a POST method written here to send the url of the current
//webpage for example www.youtube.com to url listed in the textbox,
//for example www.google.com
//May I know how can I do it? Thanks.
}
</script>
</head>
<body>
<div id ="container">
<p>Enter URL:</p>
<input type="text" id="url_textbox" name="url_textbox" />
<input type="button" id="button_enter" name="button_enter"
value="enter" onclick="handleButtonEnter" />
</div>
</body>
</html>
What you need is a <form> element, which a) has action attribute to indicate where to send the data; b) on submit sends the data (I've added an extra <input type='hidden'> to store your current pages url for sending).
<script type="javascript/text">
function handleButtonEnterClick() {
var textbox_value = document.getElementById("url_textbox").value;
document.getElementById('myUrl').value = window.location;
var form = document.getElementById('myForm');
form.action = textbox_value;
form.submit();
}
</script>
<div id="container">
<form action="" method="post" id="myForm">
<p>Enter URL:</p>
<input type="hidden" id="myUrl" name="url" />
<input type="text" id="url_textbox" name="url_textbox" />
<input type="button" id="button_enter" name="button_enter"
value="enter" onclick="handleButtonEnter" />
</form>
</div>
This should work:
<html>
<head>
<title>YouTube</title>
<script type="javascript/text">
function handleButtonEnterClick(tab)
{
var textbox_url = document.getElementById("url_textbox");
var textbox_value = textbox_url.value; //eg. value = "www.google.com"
//Set the form action to the textbox value
var the_form = document.getElementById("the_form");
the_form.setAttribute("action", textbox_value);
//Set the value of the url field to the current url
document.getElementById("url").setAttribute("value", window.location);
the_form.submit();
}
</script>
</head>
<body>
<div id ="container">
<form action="" method="post" id="the_form">
<p>Enter URL:</p>
<input type="hidden" name="url" id="url" />
<input type="text" id="url_textbox" name="url_textbox" />
<input type="button" id="button_enter" name="button_enter"
value="enter" onclick="handleButtonEnter" />
</form>
</div>
</body>
</html>
The current page location is stored in the JavaScript variable "window.location.href" (thats in Chrome, might be different elsewhere).
You also need to set the action of your form to the URL in the textarea. Suggest you put an id tag on the html form element, and use that id tag to set the action property of the form to the contents of the textbox as part part of the buttons onclick handler.
There are two options:
Use a HTML form, as Ant has shown, set the action and method attributes. Add a submit button inside the form (along with your textbox). When you click on the Submit button, your data will get posted.
Use AJAX to post your form if you want to stay in the current page
I want to create a simple form with only an input textbox and search button.
A person would type in the search term in the box and press search.
All that will do is take their search term and add it to the end of the url.
So if search term is "good italian food" the submit button would send the user to http://domain/find/good italian food
Whats the simplest way to do this?
Thank you!
<html>
<head>
<script type='text/javascript'>
function Search() {
var keyword = document.getElementById("keyword").value;
var url = "http://yourwebsite.com/find/"+keyword;
window.location = url;
return false;
}
</script>
</head>
<body>
<form name="search">
<input type="text" name="keyword" id="keyword" />
<input type="button" name="btnser" onclick="Search()" value="Search" />
</form>
</body>
</html>
I'd also suggest using encodeURI() to make it 'safe'.
http://www.w3schools.com/jsref/jsref_encodeuri.asp
use javascript and html form
create a form with a button and text box
in the post of the form call the javascript function to create the url with the user input text
<!DOCTYPE html>
<html>
<head>
<script type='text/javascript'>
function redirect(){
var s = document.getElementbyID("txt").value;
var url="http://url.com/" + s;
window.location = url;
}
</script>
</head>
<body>
<form>
<input type=''></input>
</form>
</body>
</html>
you could override the action attribute within the onsubmit event: Example
HTML
<form action="#" onsubmit="send(this)" method="post" target="_blank" >
<input id="text"/>
<input type="submit" value="submit"/>
</form>
JavaScript
function send( form){
form.action = location.href + '/'+encodeURI(document.getElementById('text').value);
}
Also, overriding the form action, or redirecting the user, within the onsubmit event will allow you to use a true submit button.
This gives the user the ability to just hit the enter key once they finish typing to submit the search without you having to write extra logic listening for the the enter key within the textbox to submit the search.
