[Javascript] Iframe: load same URL using JS

[Rees, Mark]

Hello

This doesn't work, and it doesn't work in HTML either. A single iframe is created OK but it is empty.

I suppose there is some security feature in browsers to stop infinite page loads? The thing is I only wish to do it once (as the code below shows). Just curious as to what is stopping it working.

function addIframe(){
	//reloads the same page in an iframe
	if(!document.getElementById('iframe')){
		var iFrame=document.createElement('iframe');
		iFrame.width=100;
		iFrame.height=100;
		//for some reason you cannot reload the same page in the parent

		iFrame.src=location.href;
		
		iFrame.setAttribute('id','iframe');
		document.body.appendChild(iFrame);
	}
}

function checkIframe(){
	//checks whether there is already an iframe
	if(!window.frameElement){
		alert('i am the parent page');
		addIframe();



	}else{
		//this never runs
		alert('i am the child page');

	}
}

window.onload=checkIframe;
