I have the below html button which have onclick event
<button onclick="alert('button');" type="button">Button</button>
and the following js:
$('button').on('click', function(){
alert('jquery');
});
After executing some js code by jQuery/Javascript, i want to continue with the button onclick handler eg: jquery alert first and than button alert.
i tried so many things like "remove attr and append it after executing my code and trigger click (it stuck in loop, we know why :) )" and "off" click. but no luck.
is it possible via jQuery/javascript?
any suggestion much appreciated
Thanks
Create a separate javascript function that contains what you want to do when the button is clicked (ie removing the onclick attribute and adding replacement code in its own function).
Then call that function at the end of
$('button').on('click', function(){
alert('jquery');
});
So you'll be left with something like this
function buttonFunction()
{
//Do stuff here
}
$('button').on('click', function()
{
alert('jquery');
buttonFunction();
});
<button type="button">Button</button>
A little bit tricky. http://jsfiddle.net/tarabyte/t4eAL/
$(function() {
var button = $('#button'),
onclick = button.attr('onclick'); //get onclick value;
onclick = new Function(onclick); //manually convert it to a function (unsafe)
button.attr('onclick', null); //clear onclick
button.click(function() { //bind your own handler
alert('jquery');
onclick.call(this); //call original function
})
});
Though there is a better way to pass params. You can use data attributes.
<button data-param="<%= paramValue %>"...
You can do it this way:
<button type="button" data-jspval="anything">Button</button>
$('button').on('click', function () {
var $this = $(this), //store this so we only need to get it once
dataVal = $this.data('jspval'); //get the value from the data attribute
//this bit will fire from the second click and each additional click
if ($this.hasClass('fired')) {
alert('jquery'+ dataVal);
}
//this will fire on the first click only
else {
alert('button');
$this.addClass('fired'); //this is what will add the class to stop this bit running again
}
});
