Adding multiple javascript events programmatically

Last Modified: 2016-01-24
I have successfully added a form submit event code using the following:

if (window.addEventListener){			
        window.addEventListener('load', attachFormSubmit, false);
}else if (window.attachEvent){
	window.attachEvent('onload', attachFormSubmit );

Open in new window

Now I have a textbox on the page text1 and I want to clear the value of it when it takes focus.

I tried adding the following:

function attachFocus()
	var txt = document.getElementById("text1");
	if (txt.addEventListener){		
		txt.addEventListener('focus', ClearText(txt.id), false);
    	}else if (txt.attachEvent){				
		txt.attachEvent('focus', ClearText(this.id));
		function ClearText(id)
			var obj = document.getElementById(id);

Open in new window


And I added a call to attachFocus to the window load event:

if (window.addEventListener){			
        window.addEventListener('load', attachFormSubmit, false);
	window.addEventListener('load', attachFocus, false);
}else if (window.attachEvent){
	window.attachEvent('onload', attachFormSubmit );
	window.attachEvent('onload', attachFocus );

Open in new window

So the code I added for the textbox focus event does not work. Can someone point out to me what am I doing wrong and also recommend a better way to add events via javascript. I do not want to use inline javascript
