IE event.srcElement和FF event.target 功能比较

可以捕获当前事件作用的对象,如event.srcElement.tagName可以捕获活动标记名称。

注意获取的标记都以大写表示,如"TD","TR","A"等

复制代码 代码如下:


<div>
<form>
<input type="button" value="单击查看">
<select onchange="alert(event.srcElement.options[event.srcElement.selectedIndex].value);">
<option value='001'>1</option>
<option value='002'>2</option>
<option value='003'>3</option>
<option value='004'>4</option>
<option value='005'>5</option>
</select>
</form>
</div>
<script>
function Get_srcElement(evgl)
{
  var srcElement=""
   //判断是IE 还是Firefox
  var evg=evgl.srcElement?evgl.srcElement:evgl.target;
  srcElement = srcElement + "\n" + "button_001_id----event.srcElement.id : " + evg.id
  srcElement = srcElement + "\n" + "input---event.srcElement.tagName : " + evg.tagName
  srcElement = srcElement + "\n" + "button---event.srcElement.type : " + evg.type
  srcElement = srcElement + "\n" + "单击查看---event.srcElement.value : " + evg.value
  srcElement = srcElement + "\n" + "button_001_Name---event.srcElement.name : " + evg.name
  srcElement = srcElement + "\n" + "button_001_Class---event.srcElement.className : " + evg.className
  //IE 支持parentElement FireFox支持parentNode
  srcElement = srcElement + "\n" + "form_001---event.srcElement.parentElement.id : " +     evg.parentNode.id
  srcElement = srcElement + "\n" + "event.srcElement.getattribute : " + evg.getAttribute
  alert(srcElement);
}
</script>
