怎样让火狐支持这段代码？

如题：
 <script>
function initIt1(){
if(this.name == "idbmainlist"){parent.changeColor('007CD0');}
tableColl=document.all.tags("tr");
for(i=0; i<tableColl.length; i++) {
whichEl=tableColl(i);
if(whichEl.className=="child" && whichEl.id !="$Cookies{which}"){whichEl.style.display="none";}
}
}
function expands1(el) {
expireDate=new Date;
expireDate.setYear(expireDate.getYear()+1);
whichEl1=eval(el+"Child");
var wh = (el+"Child");
if (whichEl1.style.display=="none"){
initIt1();
whichEl1.style.display="block";
document.cookie="which="+wh+";expires="+expireDate.toGMTString()+";";
}else{
whichEl1.style.display="none";
document.cookie="which="+";expires="+expireDate.toGMTString()+";";
}
}
onload=initIt1;
    </script><script language="javascript" type="text/javascript">
    function printpage(myDiv){ 
     var oldstr = document.body.innerHTML; 
    document.getElementById("btnExcel").style.display="none";
     document.getElementById("Button2").style.display="none";
    var newstr = document.getElementById(myDiv).innerHTML;
     alert(newstr);
    window.print(); 
    document.body.innerHTML = oldstr; 
    return false; 
    } 
    </script>怎样改上面的代码，让所有的浏览器都支持？

解决方案 »

  1.   

    FF浏览器写JS一般要写全路径。例如：document.getElementById...在都加上document的前面加上window.***而且FF一般都是对BYNAME比较支持。。
    希望有帮助；
      

  2.   


    <script>
    function initIt1(){
    if(this.name == "idbmainlist"){parent.changeColor('007CD0');}
    tableColl=document.getElementsByTagName("tr");
    for(i=0; i<tableColl.length; i++) {
    whichEl=tableColl[i];
    if(whichEl.className=="child" && whichEl.id !="$Cookies{which}"){whichEl.style.display="none";}
    }
    }
    function expands1(el) {
    expireDate=new Date;
    expireDate.setYear(expireDate.getYear()+1);
    whichEl1=document.getElementById(el+"Child");
    var wh = document.getElementById(el+"Child");
    if (whichEl1.style.display=="none"){
    initIt1();
    whichEl1.style.display="block";
    document.cookie="which="+wh+";expires="+expireDate.toGMTString()+";";
    }else{
    whichEl1.style.display="none";
    document.cookie="which="+";expires="+expireDate.toGMTString()+";";
    }
    }
    onload=initIt1;
    </script><script language="javascript" type="text/javascript">
    function printpage(myDiv){ 
    var oldstr = document.body.innerHTML; 
    document.getElementById("btnExcel").style.display="none";
    document.getElementById("Button2").style.display="none";
    var newstr = document.getElementById(myDiv).innerHTML;
    alert(newstr);
    window.print(); 
    document.body.innerHTML = oldstr; 
    return false; 
    } 
    </script>还有报错的话，请上错误信息。

    我把所有的代码都贴出来吧，我现在做的是，上面是一个横向的总菜单，左侧是一个树状的子菜单，然后是显示区域，我用了阿蛙的代码之后，在火狐里面还是不显示左侧菜单，  <script>
    function initIt1(){
        if(this.name == "idbmainlist"){parent.changeColor('007CD0');}
        tableColl=window.document.getElementsByTagName("tr");
        for(i=0; i<tableColl.length; i++) {
            whichEl=tableColl[i];
            if(whichEl.className=="child" && whichEl.id !="$Cookies{which}"){whichEl.style.display="none";}
        }
    }
    function expands1(el) {
        expireDate=new Date;
        expireDate.setYear(expireDate.getYear()+1);
        whichEl1=document.getElementById(el+"Child");
        var wh = document.getElementById(el+"Child");
        if (whichEl1.style.display=="none"){
            initIt1();
            whichEl1.style.display="block";
            document.cookie="which="+wh+";expires="+expireDate.toGMTString()+";";
        }else{
            whichEl1.style.display="none";
            document.cookie="which="+";expires="+expireDate.toGMTString()+";";
        }
    }

  4.   

    <script>
    先改为
    <script type="text/javascript">
      

  5.   

    在FF中点击查看-页面风格-基本页面风格。就可以看到效果了。字符编码格式用GB2312或GBK查看；
      

  6.   

    document.all.tags对于火狐是不认识的，改为document.getElementByTagName("tr");应该就可以了
