obj.innerHTML 经常用到
obj.outerHTML包括元素本身 很少用 今天看到一个可以兼容firefox 的方法
如:
<ul id="a">
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
</ul>
alert(document.getElementById("a").outerHTML);
输出:
“
<ul id="a">
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
</ul>
”
alert(document.getElementById("a").innerHTML);
输出:
“
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
<li>addsd</li>
”
下面的用来兼容firefox
if(typeof(HTMLElement)!="undefined" && !window.opera)
{
HTMLElement.prototype.__defineGetter__("outerHTML",function()
{
var a=this.attributes, str="<"+this.tagName, i=0;for(;i<a.length;i++)
if(a[i].specified)
str+=" "+a[i].name+'="'+a[i].value+'"';
if(!this.canHaveChildren)
return str+" />";
return str+">"+this.innerHTML+"</"+this.tagName+">";
});
HTMLElement.prototype.__defineSetter__("outerHTML",function(s)
{
var r = this.ownerDocument.createRange();
r.setStartBefore(this);
var df = r.createContextualFragment(s);
this.parentNode.replaceChild(df, this);
return s;
});
HTMLElement.prototype.__defineGetter__("canHaveChildren",function()
{
return !/^(area|base|basefont|col|frame|hr|img|br|input|isindex|link|meta|param)$/.test(this.tagName.toLowerCase());
});
}
