Passing parameters into a function

Copy linkTweet thisAlerts:
Apr 08.2009

I have a button. And in a function, I am changing the onClick attribute.
I have to parameters that I wish to pass into the function from the current function: ‘node’ and ‘datetext’.

var button = document.getElementById(“append”);
button.setAttribute(“onClick”, “SendEditBlog(‘”+ node + “, “+ datetext +”‘)”);

This is how the next function parses the parameters in.

function SendEditBlog(node, datetext)
{
}

When the values parse into the new function, the node variable contains that values of ‘node’ and ‘datetext’, and datetext is undefined.

What have I done??

@dmboydApr 08.2009 — What are the values of 'node' and 'datetext'? Where are those variables defined? After all, if you're using them, they need to be defined outside of the function. Otherwise, you will get an issue with undefined variables.

<i>
</i>button.onclick=function(){SendEditBlog(node,datetext)}

@haulinApr 10.2009 — say you have the variables containing this:

var node='foo';

var datetext='bar';

what you were doing resulted in this:

onClick=SendEditBlog('foo,bar') <!-- passing 1 string as an argument -->

if you want to pass their [B]values[/B], do this:
[CODE]button.setAttribute("onClick", "SendEditBlog('"+ node + "', '"+ datetext +"')"); //2 additional apostrophes around the comma[/CODE]
it will result in:

onClick=SendEditBlog('foo','bar') <!-- passing 2 string arguments -->

if you want to pass the [B]variable references[/B], do this:
[CODE]button.setAttribute("onClick", "SendEditBlog(node,datetext)");[/CODE]
which will simply result in:

onClick=SendEditBlog(node,datetext)

No. IE does not support that. Either you use the crossbrowser classical DOM 0 + anonymous function way (as I said in may previous post), or you use both the Moz and the IE models of attaching the events. See also:
