Javascript IE Event | 易学教程

问题

This works in Firefox, but not IE. Any help would be much appreciated! Thanks!

  var form = document.getElementById('theform')
    /* create the event handler */
    form.gen.onclick = function( evt ) {
        var f = evt.target.form
        var y = f.year.value
        var m = f.month.value
        genCalendar( document, y, m, 'theCalendar' )
    }

回答1:

To get the target of an event in both standards compliant browsers and IE, use

var target = evt ? evt.target : window.event.srcElement;

There's an overview of the different properties of event objects at MDC.

回答2:

As mentioned, IE does not pass the event object as a parameter. Try this:

var form = document.getElementById('theform')
  /* create the event handler */
  form.gen.onclick = function( evt ) {
    if(!evt)
      evt = window.event;
    var f = evt.target.form
    var y = f.year.value
    var m = f.month.value
    genCalendar( document, y, m, 'theCalendar' )
}

Or better yet, use a cross-browser library, like Prototype.js or jQuery.

When does this script run? You might have to run this script onload, after the DOM is fully loaded

<script>

function go()
{
  alert('dom is loaded:  register event handlers now') ;
}

</script>

<body onload=" go(); ">



</body>

This is why you should consider using a javascript library such as jquery, YUI, or prototype. These libraries abstract away the browser based differences which simplifies your coding.

From my own searching the most sucessful was this

function clickHandler(e){
 var elem, evt = e ? e:event;
 if (evt.srcElement)  elem = evt.srcElement;
 else if (evt.target) elem = evt.target;

 alert (''
  +'You clicked the following HTML element: \n <'
  +elem.tagName.toUpperCase()
  +'>'
 )
 return true;
}

document.onclick=clickHandler;
