Question

onclick doesn't work in firefox

Asked by: tdiscover

I am trying to dynamically add onclick events with parameters to img tags on my page. I found the question related to this one and came up with the following line of code:

someIMG.onclick = new Function("RemoveRoom(this.rn)");

Where rn is an attribute I have set on the img element on my page and RemoveRoom is a function in my javascript that removes certain elements from my page.

This works fine in IE but in firefox I get an error "RemoveRoom(undefined)". So firefox isn't grabbing the attribute.

Thanks for your help!

If "rn" is a string, you can do this:

someIMG.onclick = new Function("RemoveRoom('"+this.rn+"')");

If it's not, tell us what it is so we can suggest something else.

Thanks for you response Kravimir,

it is an integer

 

by: tdiscoverPosted on 2008-05-11 at 21:32:13ID: 21544673

I was just thinking about this and does it really matter what type it is? The idea is that when the user clicks on the img the value for the attribute rn is grabbed. That way I can change the value for rn at any time without having to change the function that is called for the onclick event.

- Hope this made sense, it's a bit tricky to explain

 

by: KravimirPosted on 2008-05-11 at 22:09:29ID: 21544761

Ah. Then you don't need the quotes:

someIMG.onclick = new Function("RemoveRoom("+this.rn+")");

Yes, if you're passing it as an argument, then the type does matter.

Yes, you could restructure the code. You could store the value as a property of each <img> or you could use a global object to store them.

Thanks Kravimir!

FF is case sensitive in HTML too..

onclick wont work.

onClick will work.

 

by: KravimirPosted on 2009-01-21 at 09:12:10ID: 23431646

> FF is case sensitive in HTML too..

No it isn't. And stop using inline event handlers.

 

by: tdiscoverPosted on 2009-01-21 at 14:13:58ID: 23434650

lol, fair enough Kravimir, I guess I've progressed enough in my understanding of code to go back now and fix up my inline event handlers... that's whenever I get time (like that'll ever happen, unfortunately)
