IE7. js can开发者_JAVA技巧 do this but is has some more unwanted things which i dont' want so i need simple short javascript code to enable hover in IE 6

A simple onmouseover/onmouseout has the downside that it will be also fired when the div has childnodes and you hover this child. So you will get an mouseout fired when you hover the childnode. Every framework has something like mousenter/mouseleave to handle this problem. So in JQuery it should look like this:

$('#myElement').mouseenter(toggleClass(true)).mouseleave(toggleClass());
function toggleClass(enter){
  if(enter){
     /*do something on mouseenter*/
  }else {
     /*do something on mouseleave*/
  }

/or the much shorter version/ $('#myElement')(enter ? 'add' : 'remove') + 'Class'; }

var elem = document.getElementById('divid');
elem.onmouseover = function(e) {
  if( !e ) {
    //if the browser did not pass the event information to the
    //function, we will have to obtain it from the event register
    if( window.event ) {
      //Internet Explorer
      e = window.event;
    } else {
      //total failure, we have no way of referencing the event
      return;
    }
  }
  // do operation using e
};

elem.onmouseout = function(e) {
// get e using code from above
};

This will allow you to put in code for a particular element, just change the css or do whatever else you want.
