请教： insertAdjacentHTML 在FF下的问题

[PerterPon]

IE下可以用，但是在FF下用不了，网上看了下，都是一个函数
function insertHtml(where, el, html){

where = where.toLowerCase();
if(el.insertAdjacentHTML){

switch(where){
case "beforebegin":
el.insertAdjacentHTML('BeforeBegin', html);
return el.previousSibling;
case "afterbegin":
el.insertAdjacentHTML('AfterBegin', html);
return el.firstChild;
case "beforeend":
el.insertAdjacentHTML('BeforeEnd', html);
return el.lastChild;
case "afterend":
el.insertAdjacentHTML('AfterEnd', html);
return el.nextSibling;
}
throw 'Illegal insertion point -> "' + where + '"';
}

var range = el.ownerDocument.createRange();
var frag;
switch(where){
case "beforebegin":
range.setStartBefore(el);
frag = range.createContextualFragment(html);
el.parentNode.insertBefore(frag, el);
return el.previousSibling;
case "afterbegin":
if(el.firstChild){
range.setStartBefore(el.firstChild);
frag = range.createContextualFragment(html);
el.insertBefore(frag, el.firstChild);
return el.firstChild;
}else{
el.innerHTML = html;
return el.firstChild;
}
case "beforeend":
if(el.lastChild){
range.setStartAfter(el.lastChild);
frag = range.createContextualFragment(html);
el.appendChild(frag);
return el.lastChild;
}else{
el.innerHTML = html;
return el.lastChild;
}
case "afterend":
range.setStartAfter(el);
frag = range.createContextualFragment(html);
el.parentNode.insertBefore(frag, el.nextSibling);
return el.nextSibling;
}
throw 'Illegal insertion point -> "' + where + '"';
}

请问下这个用的时候该怎么用？或者有其他的方法能够在FF中用insertAdjacentHTML？

var f = document.getElementById("f");
insertHtml("afterbegin",f,"<span style='color:#f60'>321321321321</span>")
</SCRIPT>

可以正常运行的

我看到的也是4楼那个函数 但是用的时候不知道怎么回事就是提示你 missing ) before argument list 不知道什么情况哎 后来搜索了很久 看到另外一个函数 可以用了 我还是把函数贴出来吧
function insertHTML(el, where, html) {
if (!el) {
return false;
}

where = where.toLowerCase();

if (el.insertAdjacentHTML) {//IE
el.insertAdjacentHTML(where, html);
} else {
var range = el.ownerDocument.createRange(),
frag = null;

switch (where) {
case "beforebegin":
range.setStartBefore(el);
frag = range.createContextualFragment(html);
el.parentNode.insertBefore(frag, el);
return el.previousSibling;
case "afterbegin":
if (el.firstChild) {
range.setStartBefore(el.firstChild);
frag = range.createContextualFragment(html);
el.insertBefore(frag, el.firstChild);
} else {
el.innerHTML = html;
}
return el.firstChild;
case "beforeend":
if (el.lastChild) {
range.setStartAfter(el.lastChild);
frag = range.createContextualFragment(html);
el.appendChild(frag);
} else {
el.innerHTML = html;
}
return el.lastChild;
case "afterend":
range.setStartAfter(el);
frag = range.createContextualFragment(html);
el.parentNode.insertBefore(frag, el.nextSibling);
return el.nextSibling;
}
}
}
