How can I detect whether an iframe is loaded?
I am trying to check whether an iframe has loaded after the user clicks a button.
I have
$('#MainPopupIframe').load(function(){
console.log('load the iframe')
//the console won't show anything even if the iframe is loaded.
})
HTML
<button id='click'>click me</button>
//the iframe is created after the user clicks the button.
<iframe id='MainPopupIframe' src='http://...' />...</iframe>
Any suggestions?
By the way, my iframe is created dynamically. It doesn’t load with the initial page load.
You may try this (using jQuery)
$(function(){ $('#MainPopupIframe').load(function(){ $(this).show(); console.log('iframe loaded successfully') }); $('#click').on('click', function(){ $('#MainPopupIframe').attr('src', 'https://heera.it'); }); });
Update: Using plain javascript
window.onload = function(){ var ifr = document.getElementById('MainPopupIframe'); ifr.onload=function(){ this.style.display='block'; console.log('laod the iframe') }; var btn = document.getElementById('click'); btn.onclick=function(){ ifr.src='https://heera.it'; }; };
Update: Also you can try this (dynamic iframe)
$(function(){
$('#click').on('click', function(){
var ifr = $('', {
id:'MainPopupIframe',
src:'https://heera.it',
style:'display:none;width:320px;height:400px',
load:function(){
$(this).show();
alert('iframe loaded !');
}
});
$('body').append(ifr);
});
});
I imagine this like that:
<html>
<head>
<script>
var frame_loaded = 0;
function setFrameLoaded()
{
frame_loaded = 1;
alert("Iframe is loaded");
}
$('#click').click(function(){
if(frame_loaded == 1)
console.log('iframe loaded')
} else {
console.log('iframe not loaded')
}
})
</script>
</head>
<button id='click'>click me</button>
<iframe id='MainPopupIframe' onload='setFrameLoaded();' src='http://...' />...</iframe>
You can try onload event as well;
var createIframe = function (src) {
var self = this;
$('<iframe>', {
src: src,
id: 'iframeId',
frameborder: 1,
scrolling: 'no',
onload: function () {
self.isIframeLoaded = true;
console.log('loaded!');
}
}).appendTo('#iframeContainer');
};

load()is deprecated, but that's just because it was conflicting with the ajax function. The recommended replacement is simplyon("load"). (Unfortunately, the docs don't quite make clear that that's all you need to do.).click,.change, etc., which are aliases of their correspondingoncounterpart).
