How can i dynamically Change onmouseover, onmouseout and onClick WITH parameters?
I have an image:
<img id="reqPic" src="mark.png" />
I also have declared a flag earlier on in the page:
<script type="text/javascript">
var isToolTipEnabled = true;
</script>
I now want to be able to check the flag and if its true, assign the onmouseover and onmouseout events. However, the onmousover event has to be changed to another fun开发者_Python百科ction called Tip('string') which takes in a string. I have seen other questions on here on how to change this but it I dont see how I can pass paramters to the new function I want to change to.
The onClick would be changed to something like this:
onClick="javascript:toggleHelp('reftypeHelp');";
Any help on this would be greatly appreciated.
Thanks!
document.getElementById("reqPic").onmouseover = function() { Tip('This is the string.'); };
You could have an onload event on your body tag which calls a function that checks necessary values.
<script type="text/javascript">
var isToolTipEnabled = true;
function eventAdder() {
if (isToolTipEnabled) {
var img = document.getElementById('reqPic');
img.onmouseover = function() {
Tip('string');
}
img.onmouseout = whateverElse;
}
}
</script>
<body onload="eventAdder();">
with jQuery you could use the hover function but yeah creating an inline function works too
