insertAdjacentElement与firefox

Question

现在问题也很简单了，就是用这个insertAdjacentElement函数能替代下面文件中的insertAdjacentElement调用，能在firefox中显示
insertAdjacentElement=function(where,parsedNode){
        switch(where){
            case "beforeBegin":
                this.parentNode.insertBefore(parsedNode,this);
                break;
            case "afterBegin":
                this.insertBefore(parsedNode,this.firstChild);
                break;
            case "beforeEnd":
                this.appendChild(parsedNode);
                break;
            case "afterEnd":
                if(this.nextSibling)
                    this.parentNode.insertBefore(parsedNode,this.nextSibling);
                else
                    this.parentNode.appendChild(parsedNode);
                break;
            }
        }function alai_tree(imageList,indent,toObject,labelStyle)

Answer 1

- -刚在另一个帖子里跟人说firefox不支持insertAdjacentHTML和insertAdjacentElement，就发现哈，不错，我也自己写个这类的函数方便用。不过，反正都是自己写函数，就干脆用些简短的名字吧。

Answer 2

跨浏览器啊，最头疼了
现在google也在凑热闹，唉

Answer 3

为什么不这么写呢？
if(window.HTMLElement){
    HTMLElement.prototype.insertAdjacentElement=function(where,parsedNode){ 
        switch(where){ 
            case "beforeBegin": 
                this.parentNode.insertBefore(parsedNode,this); 
                break; 
            case "afterBegin": 
                this.insertBefore(parsedNode,this.firstChild); 
                break; 
            case "beforeEnd": 
                this.appendChild(parsedNode); 
                break; 
            case "afterEnd": 
                if(this.nextSibling) 
                    this.parentNode.insertBefore(parsedNode,this.nextSibling); 
                else 
                    this.parentNode.appendChild(parsedNode); 
                break; 
            } 
        } 
    HTMLElement.prototype.insertAdjacentHTML=function(where,htmlStr){ 
        var r=this.ownerDocument.createRange(); 
        r.setStartBefore(this); 
        var parsedHTML=r.createContextualFragment(htmlStr); 
        this.insertAdjacentElement(where,parsedHTML); 
        } 
    HTMLElement.prototype.insertAdjacentText=function(where,txtStr){ 
        var parsedText=document.createTextNode(txtStr); 
        this.insertAdjacentElement(where,parsedText); 
        } 
}

Answer 4

var ifraBody = tabContenIfra.document.getElementsByTagName("body").item(0);
ifraStrs = fStr.split(",");
var ifraDiv=document.createElement("div");
ifraBody.insertAdjacentElement("beforeEnd",ifraDiv);但是这个只能在ie中使用,看看把你写的方法嵌入,看可不可以!
