Something like this but instead for clicking the button have it done by calling it programmatically.
<script>
function myFunction()
{
document.getElementById("demo").innerHTML = "Hello World";
}
</script>
button onclick="myFunction()">Click me
id="demo"
I don't think "click for itself" is the right way to think about this problem. A better way would be to modularize the functionality of the button click as such:
doOnClickButton()
Then, when the page loads, simply execute this function.
Example with jQuery:
$(document).ready(function() {
doOnClickButton();
})
Following the nmg49 answer, you can do it without jQuery using the DOMContentLoaded event:
document.addEventListener('DOMContentLoaded', function() {
doOnClickButton();
});
Simply put, just skip the button part and call the function on page load. If you were doing this, use a JavaScript such as the one shown.
setTimeout(function () {
alert("Hello world!");
}, 1);

The problem I am encountering is that I just want to access the alert command inside window onload. The purpose of this code is that I want to wrap 5 different diagrams in methods like (table1(), table2(), table3(), table4(), table5()), then I wish to use JQuery event to enable the user too select which diagram they want to see once a time.
Below is a JavaScript file, keep in mind that the alert command is not accessible..
(function table4(){
$(window).on("load", function() {
alert('Test');
});
}());
$(window).load(function(){}) is only called if it's bound before the event.
Try to use the $(document).ready function:
(function table4(){
$(document).ready(function() {
alert('Test');
});
}())

Dont "hide" in table4 function
$(document).ready(function() {
alert('Test');
}
I'm working with a wordpress theme and I need to activate a button when the page loads, but none of the following has worked for me (my button has the ID "reset"):
$(document).ready(function() {
$("#reset")[0].click();
});
--
$(document).ready(function(){
$("#reset").click();
})
--
$(window).load(function(){
$('#reset').click();
});
I put the code in the header or in the page where i need to activate the button, but does not work.
Thanks!
I give you example here
$(document).ready(function(){
$("#reset").click();
})
the code above should work.
JavaScript does not allow seamless programmatic triggering of an actual click event.
What you could do is
declare the click callback as a separate, named function
e.g.
function myClickCallback(e) {
// Do stuff here
}
Set this as the click callback of your button (e.g. $('#reset').on('click', myClickCallback)).
Invoke the callback when the page loads (e.g. $(document).ready(myClickCallback);)
I am not sure why you 'd want this functionality, since it sounds weird. From reading your description, by "activating", you could also mean enabling the button. To do that you should do something like the following
$(document).on('ready', function (e){
$('#reset').removeAttr('disabled');
});
You may need to refer to it using jQuery instead of $:
The jQuery library included with WordPress is set to the noConflict() mode...
https://codex.wordpress.org/Function_Reference/wp_enqueue_script#jQuery_noConflict_Wrappers
$(document).ready(function(){
$("#reset").trigger('click');
});
Use the function Trigger with the event click
$(document).ready(function(){
$("#reset").trigger('click');
});
This what works for me:
$(function () {
$('#btnUpdatePosition').click();
});
On the button event, the JQuery binding event doesn't work:
$('#btnUpdatePosition').click(function () {
alert('test again');
});
But it works when I added the event on attribute declaration:
<input type="button" value="Update" id="btnUpdatePosition" onclick="alert('Click has been called')" />
You can also call if you have a function on element:
<input type="button" value="Update" id="btnUpdatePosition" onclick="fncShow();" />
<script>
var el = document.getElementById('btn');
e1.onclick=function()
{
//
alert('hello');
};
</script>
<button type="button" id="btn" >Log-in</button>
I am simply testing how unobstrusive javaScript works with a simple button onclick() event but when i click on the Log-in button nothing happens alert box doesn appears
Your script appears before the button.
It runs before the button is added to the DOM.
document.getElementById('btn') doesn't find the button because the button doesn't exist then.
Move the script after the button or put it in a function and call that function after the button exists (e.g. from the window's load event).
Also, don't rename your variables in the middle of your code. A lower case L and the numeral 1 aren't interchangeable.
The issue is you try to attach the handler before the element exists. <script> tags are executed immediately and so the browser hasn't created the button element at that time.
A solution would be to wrap it in window.onload:
window.onload = function(){
var el = document.getElementById('btn');
e1.onclick=function()
{
//
alert('hello');
};
};
Alternatively you can use the DOMContentLoaded event. This differs from onload because it doesn't wait for images and CSS to be loaded. It isn't supported by IE8 or lower though:
document.addEventListener("DOMContentLoaded", function(event) {
console.log("ready to attach events");
});
yes as said by above 2 answers you can wrap your code in window.onload else you can write a function and call it onclick event of button as shown below
function myfunction() {
alert('Hello');
};
<input type="button" onclick="myfunction()" value="Click Me!" />

I try make button with jQuery I call the JavaScript function, but I got problem :
after page loaded, first time click on mybutton there is no reaction
second click will execute function twice
third click will execute function three
and more
Why my code execute many more ? I just want " 1 click 1 execution JavaScript function"
my code like this
<script type="text/javascript" language="javascript">
function showcase(){
var foo = function () {
alert('tutup');
};
$('#create-new').on('click',foo);
return false;
}</script> <button class="button" id="create-new"onclick="return showcase();">show text</button>
please help me out this problem
for try my full error code at here http://jsbin.com/ovucer/1/edit
You are registering multiple click event listeners to the element
Every time you click on the button you are adding a new click handler to the button using showcase method, it is not needed
<button class="button" id="create-new">show text</button>
<script type="text/javascript" language="javascript">
var foo = function () {
alert('tutup');
};
$('#create-new').on('click',foo);
</script>
This happens because you bind a click event, which calls showcase() function, which as well binds a new click event, that calls foo() method. And the last iteration is repeated every time you click the button. This is sort of recursion working here.
The right way will be to bind a click event a single time, after the element is loaded:
<button class="button" id="create-new">show text</button>
<script type="text/javascript">
$("#create-new").on("click", function() {
alert("tutup");
});
</script>
You are registering an onclick function in onclick,
use this:
$('#create-new').on('click', function(){ alert('text button'); return false; });
You're binding the click event twice. Using onclick on the HTML and over again, using jQuery .on().
To make your life easier, and as you're using jQuery already, do it just at the document ready event:
var foo = function () {
alert('text button');
return false;
};
$(function () {
$('#create-new').on('click',foo);
});
And fix your HTML bit, by removing the onclick:
<button class="button" id="create-new">show text</button>
try this in your script tag and delete the onclick event in the button:
var foo = function () {
alert('tutup');
};
$('#create-new').on('click',foo);
return false;
I am using ColorBox inline functionality and I have created a button which I've set to close the window when clicked:
$('.closebutton').live('click', function(){
$.fn.colorbox.close();
});
I have another function which I want to run when the button is clicked, so I've used:
<button class="closebutton" onclick="myFunction();">Close</button>
Problem is the myFunction is not working above.
Any ideas please?
UPDATE:
Here is where the code is:
<script type="text/javascript">
jQuery(document).ready(function() {
$(".inline").colorbox({inline:true, width:"50%"}); //for colorbox inline
$('#cboxClose').remove(); //remove popup window close button
$('.closebutton').live('click', function(){
$.fn.colorbox.close();
myFunction();
});
Adding myFunction(); before or after $.fn.colorbox.close(); is not working
myFunction code: (This goes after the code above on the page)
<script type="text/javascript">
function myFunction() {
$("#ajax-form").submit(function(){
$.post("update.php",
$("#ajax-form").serialize(),
function(data){
$('#jqm').attr('src',
$('#jqm').attr('src'));
}
);
return false;
});
}
</script>
UPDATE 2:
I'll try to explain better: I have a form and input on the main page that works find, so when you add some text to the input box and submit then form then the value of the input is submitted.
Now, when I put that same input in the inline area of colorBox so that it appears inside the popup window the value is not submitted. I've tried grabbing JS errors on firebag but cannot see anything there.
Hope this helps.
Why not just add myFunction() before $.fn.colorbox.close();? That way you can be sure what order things are handled in.
Instead of using inline javascript, you could simply do something like this :
$('.closebutton').live('click', function(){
$.fn.colorbox.close();
myFunction();
});
I believe the problem is that myFunction() (the onClick attribute) is being overridden by jQuery. If you want your function to execute whenever a .closebutton is clicked just use:
$('.closebutton').live('click', function(){
$.fn.colorbox.close();
myFunction();
});
If its only for that button, try adding an id to that button and:
$('.closebutton').live('click', function(){
$.fn.colorbox.close();
if($(this).attr('id') == 'exampleID')){
myFunction();
}
});
Ok so, after reading your update #2, I understand that actually your problem is not that the myFunction code doesn't execute right.
The problem is that you moved your input inside the colorbox, so its value doesn't submit with the form, wich is normal because the input is now outside the form.
You could either simply move your whole form inside the colorbox, or use javascript to copy the value of the input you moved outside of your form in a hidden input.
