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

注意获取的标记都以大写表示，如"TD","TR","A"等

<div id="div_001"> 
<form id="form_001"> 
<input type="button" id="button_001_id" name="button_001_Name" value="单击查看" class="button_001_Class" onclick="Get_srcElement(event)"> 
<select name="selectname" 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);
