I cannot get my button to trigger the javascript. This seems to be quite straightforward? What is keeping the alert from showing up?
<script type="text/JavaScript"
src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js">
$(document).ready(function ()
{
$("#submitButton").click(function (e) {
alert("Hello!!");
});
});
</script>
<input type="submit" name="submitButton" id="submitButton" class="form-input" value="ButtonName"
OnClick="ActionName" runat="server" />
You should end of the script tag if you add source only. And you should add extra script tag for internal script. And input type should be button because you are not submitting a form in here. If you will submit something, you should use a form element and listen it's submit event. You can use input type="submit" for it.
$(document).ready(function ()
{
$("#submitButton").click(function (e) {
alert("Hello!!");
});
});
<script type="text/JavaScript"
src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<input type="submit" name="submitButton" id="submitButton" class="form-input" value="ButtonName"
OnClick="ActionName" runat="server" />

This Code Works but when i copy and paste into it, it doesn't submit.
<script src="jquery-3.2.1.min.js"></script>
<form id="Form" action="pro_add_invoice.cfm" method="post">
<input id="here"name="htno" type="text" value="" />
<input id="subHere" type="submit" value="Submit" />
</form>
<script>
$('#here').keyup(function(){
if(this.value.length ==10){
$('#Form').submit();
}
});
</script>
I'm assuming you just want to submit the form after ten characters are entered. You can use $().submit() instead and pass in the id of the form.
<form id="Form" action="sell.cfm" method="post">
<input id="here"name="htno" type="text" value="" />
<input id="subHere" type="submit" value="Submit" />
</form>
<script>
//$('#here').keyup(function(){
// if(this.value.length ==10){
// $('#Form').submit();
// }
//});
var input = document.querySelector('#here');
input.addEventListener('keyup', checkLength);
function checkLength(e){
if(e.target.value.length===10){
document.forms["Form"].submit();
}
}
</script>
If you want to submit the form you cannot use click event handler. That's only for click events. you need to call the submit method of the form element to submit the form.
Change your If statement to execute the following:
Vanilla JS:
document.forms.Form.submit();
or
JQuery:
$('#Form').submit();
SO...
<script>
$('#here').keyup(function(){
if(this.value.length ==10){
$('#Form').submit();
}
});
</script>
I think the problem here is this context is not belong to #here, the scope in the anonymous function (probably) belong to window.
I didn't try it yet but maybe this solve the problem, try change this to ('#here')
i am trying to make a list and submit button and the user enters the list size and then after clicking on a button the form is submitted (list size is sent to the servlet ) and an alert should appear .. but the alert is not working .. here is my code
<body>
<form action="ServerSide" method="post">
Enter list Size:<input type="text" name="listsize">
<input type="submit" value="Submit" id="btn">
</form>
<script type="text/javascript">
$(document).ready(function(){
$("#btn").click(function(){
alert("anything");
});
});
</script>
</body>
You can try this:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("form").submit(function(){
alert("Submitted");
});
});
</script>
</head>
<body>
<form action="">
First name: <input type="text" name="FirstName" value="Mickey"><br>
Last name: <input type="text" name="LastName" value="Mouse"><br>
<input type="submit" value="Submit">
</form>
</body>
</html>

First of all make sure you are including/referencing JQuery Libray before you use JQuery. it should work.
Secondly you can use this
<body>
<form action="ServerSide" method="post" id="myform">
Enter list Size:<input type="text" name="listsize">
<input type="button" value="Submit" id="btn">
</form>
<script type="text/javascript">
$(document).ready(function(){
$("#btn").on('click',(function(){
alert("anything");
}));
});
</script>
</body>
I also notice that you had used input type submit it will submit form instead of calling click function. you should change type to button
if you want to do something on form submission you have to use onsubmit event
<body>
<form action="ServerSide" method="post" id="myform">
Enter list Size:<input type="text" name="listsize">
<input type="submit" value="Submit">
</form>
<script type="text/javascript">
$(document).ready(function(){
$("#myform").submit(function(){
alert("anything");
});
});
</script>
</body>
For this you don't need to add click listener on the submit button. once you submit form it will show you alert.
Here is my HTML code
<form id="form1" runat="server">
<input id="q" required />
<input id="btn" type="submit" value="Search" />
</form>
I'm trying the HTML 5 required feature in asp.net. The above code works. But a post back also occurs. Is there a way to prevent the post back using JavaScript, jQuery or any other method? I tried to prevent the post back using jQuery
$(document).ready(function () {
$('#btn').click(function (evt) {
evt.preventDefault();
});
});
But this makes the required validation not to fire.
Note: There are more than one button in the form.
change "click" event to "submit", and bind it not to btn but to form
$(document).ready(function () {
$('#form1').on("submit", function (evt) {
evt.preventDefault();
});
});
Here is the updated JsFiddle which has two inputs (one is required) and two buttons (one is submit).
HTML:
<form id="form1" method="get" action="http://example.com">
<input id="q" required />
<input id="w" />
<input id="btn" type="button" value="Cancel" />
<input id="btn" type="submit" value="Submit" />
Javascript
$('#form1').on("submit", function (evt) {
evt.preventDefault();
});
If that doesn't answer your question, please elaborate
I have two buttons, and I want to apply one action to another. For example.
<form>
<input type="submit" />
</form>
<input type="submit" />
I want to make the second button submit the form, despite being outside of the form.
You should make them of type button, and give your form an id.
Markup:
<form id="myForm">
<---STUFF---->
<input type='button' id='otherButton'>
</form>
<input type='button' id='someButton'>
jQuery:
$('#someButton').click(function() { $('#myForm').submit(); });
$(':input:last').click(function()
{
$('form').submit();
});
// enable form submit on the second <input>
$('input[type=submit]').click(function(){
$('form').submit();
});
// disable the inner <input>
$('form input[type=submit]').click(function(){
return false;
});
Something like this should do your trick.
If you want the second button to do everything the first can do (not just submit), you can try something like this:
html
<form>
<input id="insideButton" type="submit" />
</form>
<input id="outsideButton" type="submit" />
jsJQUERY
$("#outsideButton").click(function() {
$("#insideButton").trigger("click");
});
you can using jQuery $("#test").click() if you have jQuery instead of the document... stuff below or the way below will work without jQuery
<form name="testForm1">
<input type="submit" id="test" />
</form>
<!-- use this when not in a form: -->
<button onclick="button1_click();" id="button1"></button>
In your head tag
<script type="text/javascript">
function button1_click(){
document.forms.testForm1.submit();
}
</script>

i have Html document A.html and javascript file A.js, how to write a code in javascript within html body THAT SPECIFIES FUNCTION res AS THE EVENT HANDLER FOR THE onclick EVENT FOR THE BUTTON DEFINED IN THE FORM?
A.html-----------
<body>
<form>
<input type = "button" id="butt1" value = "Press for Results" /><br />
</form>
<script type="text/javascript">
</script>
</body>
This is a pretty poorly written question, but I think what you want to do is pretty straightforward. When you include an external script with
<script type="text/javascript" src="A.js"></script>
It's all there for the following execution. Thus if A.js has the following:
function res() {
...
}
You can use specify that in your HTML, as such:
<button onclick="res()" value="call res()">
I think this is what you mean..
a.html:
<head>
<script type="text/javascript" src="a.js"></script>
</head>
<body>
<form>
<input onclick="javascript:res();" type="button" id="butt1" value="Press for Results" /><br />
</form>
</body>
a.js:
function res()
{
alert("function logic to go here");
}
If you want all the code on the one page..
<head>
<script type="text/javascript">
function res()
{
alert("function logic to go here");
}
</script>
</head>
<body>
<form>
<input onclick="javascript:res();" type="button" id="butt1" value="Press for Results" /><br />
</form>
</body>
A.html
<script type="text/javascript" src="A.js">
<form>
<input type="button" name="test" value="Click me" onclick="inform()">
</form>
A.js
function inform(){
alert("You have activated me by clicking the grey button! Note that the event handler is added within the event that it handles, in this case, the form button event tag")
}
All at once
<script type="text/javascript">
function inform(){
alert("You have activated me by clicking the grey button! Note that the event handler is added within the event that it handles, in this case, the form button event tag")
}
</script>
<form>
<input type="button" id="button" name="test" value="Click me" onclick="inform()">
</form>
Calling function in javascript
if(condition in which you want onclick to b called)
document.getElementById('button').click();
