Goose Posted April 20, 2008 Share Posted April 20, 2008 Basically I have some code in Javascript that looks like this: ... obj.onmouseover = showTooltip; obj.onmouseout = hideTooltip; ... When I am doing this, is there a way to pass in an argument to the showTooltip function? I know that when the showTooltip function actually gets called it has the object that called it, which can be accessed by the reference this. I know this is illegal and won't run, but I want to do something like this: ... obj.onmouseover = showTooltip('Some random text.'); obj.onmouseout = hideTooltip; ... Thanks so much!

Psycho Posted April 20, 2008 Share Posted April 20, 2008 I don't know that you can do that. But, I can think of two solutions that are similar (except where you set the "random" text). Both solutions involve creating a custom attribute for the object and setting the value of that attribute to the "random text". Then in the function showTooltip you don't need to pass it the text - you can access the appropriate text with the attribute, such as "this.getAttribute('tooltip')". Option 1 - Set the attribute when creating the event handlers ... obj.onmouseover = showTooltip('Some random text.'); obj.onmouseout = hideTooltip; obj.tooltip='Some random text.'; ... Option2 - set the attribute in the field itself <div tooltip="Some random text">This is the object</div> Quote Link to comment Share on other sites More sharing options...
Goose Posted April 20, 2008 Author Share Posted April 20, 2008 Interesting... I didn't know that I could make my own attributes. I think I will explore that option. I know that the second option won't really work because I am dynamically creating the object. I will let you all know how it works out.

Goose Posted April 25, 2008 Author Share Posted April 25, 2008 obj.onmouseover = function(){showTooltip('Some random text.');}; Is there a way to also pass in the event handler with this method? Quote Link to comment Share on other sites More sharing options...
Goose Posted April 25, 2008 Author Share Posted April 25, 2008 O figured it out obj.onmouseover = function(e){showTip(e, 'Some random text.')} This allows me to pass the event and another argument into the showTip function. Quote Link to comment Share on other sites More sharing options...
