Event Handlers

[jafisher2000]

Could someone tell me how to write event handlers for Dhtml objects such as window.onunload using javascript but not enclosing the actio to be executed within a standalone script tag?

Simply put the script statements into the event handler declaration directly, as per:

<a href=&quot;[URL unfurl="true"]http://www.tek-tips.com&quot;[/URL] onclick=&quot;confirm('Do you really want to leave my site?')?return true; return false;)&quot;>

How does one get a string variable inside an event handler that is declared inside of a string used to set innerHTML?
See code below :

/****************************************/
function addCommentBox( idStr ) {
var el = document.createElement( "div" );
var input = &quot;<INPUT TYPE='BUTTON' onclick='click( this, idStr )' value='Ok'/>&quot;;
el.innerHTML = input;
document.body.appendChild( el );
}

Problem is you need a way to put quotes around the idStr variable which is a parameter to the onclick handler... Nothing I've tried seems to work properly! Thanks for any thoughts or suggestions!

Just use the createElement and appendChild functions in the same manner for the button as you do for the div:

function addCommentBox(idStr){
 var el = document.createElement( "div" );
 var btn = document.createElement( "input" );
 btn.setAttribute("type", "button");
 btn.setAttribute("onclick", "doSomething(this, '" + idStr + "')");
 btn.setAttribute("value", "Ok");
 el.appendChild(btn);
 document.body.appendChild(el);
}

No you wouldn't... Putting quotes around idStr would make it the physical string &quot;idStr&quot;, which you don't want. Unquoted is what you need.

Delvis,

you just need to escape the quotes:

var input = &quot;<INPUT TYPE='BUTTON' onclick='click( this, \&quot;' + idStr + '\&quot; )' value='Ok'/>&quot;;
