I try to hide the text with a button click, not sure how it is done:..
<script type="text/javascript">
$('.HideButton').click(
function () {
$('#disclaimer').hide();
}
);
</script>
The body:
<p id="disclaimer" > DDDDDDDDDDDDDDDDDDDDDDDDDD</p>
<asp:Button ID="Button1" CssClass="HideButton" runat="server" Text="Hide" />
You need to wrap it in the ready handler, but apart from that it should work:
$(function() {
$('.HideButton').click(function () {
$('#disclaimer').hide();
});
});
(demo - slighty changed in order to overcome ASP dependency.) Do note, that the button may have other side-effects, too, cf. #Zootius' answer.
Your button should not be an asp:Button. Do this instead.
<input type="button" value="Hide" class="HideButton" />
This is because the asp:Button causes a full postback on click (check your page source - it renders as a form-submit button).
Put it in "document.ready"
document.ready(function() {
//Your code here
});
Try:
<script type="text/javascript">
$(document).ready(function(){
$('.HideButton').click(function () {
$('#disclaimer').hide();
});
});
</script>
You need to tell the browser when to add the listener to the button. Usually that is done in the ready function because you want it always as soon as the page is rendered.

I would like to call a Javascript function once the button is displayed on screen. What I am looking for is similar to the 'onclick' attribute:
<input type="button" class="button-class" onclick="function(this)">
However, I would like the function to be called as soon as the button is displayed on screen i.e. it should be instantaneous (button creation=function call). I have already tried 'onload' but this does not seem to work. Is there a way to do this please?
Thank you
Put an script element invoking the function after the button element
<input type="button" class="button-class" onclick="fn(this)" value="button" id="btn">
<script>
function fn(obj){
console.log(obj)
}
fn(document.getElementById("btn"));
</script>
#Questionnaire, you can't do what you want since an action should take place for a button (click event) to execute code.
As a good practice, load your Javascript code after the page is done loading. This is to avoid blocking the rendering of HTML code since
Javascript is synchronous.
...
<script type="text/javascript">
function init() {
// Code for your button function here
}
window.onload = init();
</script>
</html>
The code above is pretty much it.
Just write the function name in onclick property instead of function(this) like the following..
<script>
function myFunc(e){
//do something
}
</script>
<input type="button" class="button-class" onclick="myFunc(this)">
#Bartman pointed out how the .ready() funtion handled it as a document.ready.
So i came up with a small solution to run the waanted funtion once the input button is created. Hotfix but cant imagine another solution
I hope this helps. If not please add a comment so i can edit the answer.
function clickFunc(e) {
alert("click event");
}
function loadFunc() {
alert("load event");
}
$("#button").click(function() {
$("div").append("<input id=\"but\" type=\"button\" class=\"button-class\" onclick=\"clickFunc(this)\">");
$("body").append("<script>loadFunc();<\/script>");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="button" type="button">
<div></div>
I want callback alert after submit form, but doesn't worked. Submit not execute.
Only $("#formImpressao").submit(); worked fine.
I try too use $(document).ready(function () { ... :( No Success
Whats wrong?
Sorry for my bad english
<div id="HiddenFormTarget" style="display:none;">
<form id="formImpressao" method="post" target="frmPrint" action="/VisualizarRelatorios/ImprimirRelatorio.aspx""></form>
</div>
<iframe id="frmPrint" name="frmPrint" width="0" height="0" runat="server">
</iframe>
<script language="javascript" type="text/javascript">
$("#formImpressao").submit(function () {
alert('Test');
});
$("#formImpressao").submit();
</script>
$("#formImpressao").submit(function (e) {
e.preventDefault();
alert('Test');
//Insert AJAX to submit form data
});
e.preventDefault() will prevent the default action of the submit event, and then run your alert, but it will NOT submit the form. For that, you will need to use AJAX. It's simple enough to understand, and there are plenty of SO topics on the use of it, so I won't reiterate. But preventDefault() will get you started.
<form id="formImpressao" method="post" target="frmPrint" action="/VisualizarRelatorios/ImprimirRelatorio.aspx""></form>
</div>
Now you can use two ways to submit the form using only jQuery,Recommended method
<script>
$(document).ready(function(){
//instead of id selector use tag selector
$("form").submit(function () {
alert('Test');
});
});
</script>
Another using id selector which is already posted
I reproduce this situation and all right:
[https://codepen.io/piotrazsko/pen/mqMrgo][1]
(1) There appears to be an extra quote in your form tag.
(2) Have you tried your approach without the target attribute in the form tag?
e.g. -
<form id="formImpressao" method="post" action="/VisualizarRelatorios/ImprimirRelatorio.aspx"></form>
I have the below script in my code:
<script src="~/Scripts/jquery-2.2.3.js"></script>
<script type="text/javascript">
$(document).ready()
{
$("#hdnTest").text('#ViewBag.Test');
$("#frmRouter").submit();
};
function submitform()
{
$("#frmRouter").submit();
}
</script>
I also have the below html in my mvc view:
<form id="frmRouter" method="post" action="https://localhost/Destination/Index">
<div>
<input type="hidden" id="hdnTest" name="hdnTestName" />
</div>
Click
</form>
When I click on the hyper link, the form is getting posted to the action URL. However, the form submit inside the document.ready doesn't work. Why is it so?
You've written the code in a way that's syntactically correct, but functionally wrong:
$(document).ready(function() {
$("#hdnTest").text('#ViewBag.Test');
$("#frmRouter").submit();
});
is what you want. The .ready() method should be passed a reference to a function. It doesn't have to be an anonymous function (as above), but that's pretty common.
Your code was missing the function, so jQuery just basically ignored the method call. The subsequent block of code was executed, but since the form element didn't exist in the DOM it didn't do anything.
Your document.ready has not the correct syntax.
You have two ways to perform a document.ready function.
$(document).ready(function () {
$("#hdnTest").text('#ViewBag.Test');
$("#frmRouter").submit();
});
$(function () {
$("#hdnTest").text('#ViewBag.Test');
$("#frmRouter").submit();
});
$(document).ready(function(){
$("#id_of_your_anchor_tag").click(function(){
$("#hdnTest").text('#ViewBag.Test');
$("#frmRouter").submit();
});
});
Click
Try this way,
Hope it helps !
I have a hyperlink/image button that uses javascript to submit a form,
<p>
<a href="#" onclick="checkOutFrm.submit();">
<img src="images/btn-checkout-basket.gif" width="169" height="28" alt="Checkout" border="0" />
</a>
</p>
and would like to add a checkbox that would disable the hyperlink until it is checked. How would I go about doing this?
Any help greatly appreciated, S.
You should not, in general:
Mix your JavaScript into your HTML markup (you should attach your logic handlers programmatically),
(ab)use anchor elements for JavaScript only (you should use a button, or put the onclick handler on the img directly), nor
place a form's submission handler on the click of a single element (you should instead handle the onsubmit event of the form).
I don't know the specifics of your situation, but I would do this in your HTML file:
<!-- Put a valid doctype here -->
<html><head>
<script type="text/javascript" src="submit.js"></script>
</head><body>
<form id="myform" ...>
<label>
<input type="checkbox" name="accept" id="accept-box" />
I accept
</label>
<button type="submit" id="submitter" disabled="disabled">
<img src="..." />
</button>
</form>
</body></html>
...and this in your submit.js file:
window.onload = function(){
var accept = document.getElementById('accept-box');
var submit = document.getElementById('submitter');
accept.onclick=function(){
submit.disabled = !accept.checked;
};
document.getElementById('myform').onsubmit = function(){
// Prevent form submission by any means unless
// the accept button is checked.
return accept.checked;
};
};
(Well, actually, I personally would use jQuery for handling the JS side of things :)
$(function(){
$('#accept-box').click(function(){
$('#submitter').attr('disabled',!this.checked);
});
$('#myform').submit(function(){
return $('#accept-box').attr('checked');
});
});
You can use CSS to style away the button surrounding the image, if you like:
#submitter { border:0; padding:0 }
Before submitting data, you can check the value of the checkbox first.
<a href="javascript: if(getElementById('CheckBoxID').checked) { checkOutFrm.submit(); } else { return false; }">
If you use jQuery you'd rather do it this way:
$(function(){
$("a").click(function(e){
e.preventDefault();
$("#CheckBoxID").val() && $("form").submit();
});
});
You can use Jquery Validator http://bassistance.de/jquery-plugins/jquery-plugin-validation/ to force it.
I've got UpdatePanel with Div
<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1">
<div class="pnlFind" style="display:none;">
</div>
</telerik:RadAjaxPanel>
wanna use js for showing this div
<script type="text/javascript">
function pageLoad(sender, args) {
if (args.get_isPartialLoad()) {
$('.btAddUser').click(function () {
$('.pnlFind').show('slow');
$('.pnlFind').attr('display', 'block');
return false;
});
}
}
</script>
but after partial postback, I got div invisible again(right! restore DOM) How can I remember that div should be always visible after button click. Thanks
You have to inject javascript into the page to simulate the click event again. Page.RegisterClientScriptBlock or Page.RegisterStartUpScript should do it.
