Question

打击代码在IE上工作正常，但在Firefox上不起作用，为什么？这是我的代码的一些问题？怎么解决？谢谢！

<html>
<head>
<style>
body{font-family:Arial;font-size:12px;font-weight:normal;line-height:28px;}
.product_tips{
width:500px;
background:#f0f0f0;
border:1px solid #ccc;
padding:8px;
margin-top:3px;
}
span{cursor:pointer;}
</style>
<script type="text/javascript">
    function get(id){ 
        return document.getElementById(id);
    }
    function showTip(e){
        if(get("product_tips").style.display == "none"){
        get("product_tips").style.display = "block";
    } else{
        get("product_tips").style.display = "none";
    }
    stopBubble(e)
}
function stopBubble(e) {
    if (e){
     e.stopPropagation();
     }
    else{
     window.event.cancelBubble = true;
    }
}
document.onclick = function(){
        get("product_tips").style.display = "none";
    }
</script>
</head>
<body>
<div class="relative_">
<label><input type="text" name="#" value="" id="product_name" maxlength="6" /></label>&nbsp;&nbsp;<span onclick="showTip();">help ?</span>
                <div id="product_tips" class="product_tips" style="display:none;" onclick="stopBubble();">
                    <div class="product_inbox">
                        <p>content content content content content content content content content content content content content content content content content content content content </p>
                    </div>
                </div>
                </div>

尽量不在属性中设置事件处理程序，而是在脚本中设置它。以下适用于IE和Firefox：

<html>
<head>
<style>
body{font-family:Arial;font-size:12px;font-weight:normal;line-height:28px;}
.product_tips{
width:500px;
background:#f0f0f0;
border:1px solid #ccc;
padding:8px;
margin-top:3px;
}
span{cursor:pointer;}
</style>
<script type="text/javascript">
  function get(id){
    return document.getElementById(id);
  }
  function showTip(e){
    if(get("product_tips").style.display == "none"){
    get("product_tips").style.display = "block";
  } else{
    get("product_tips").style.display = "none";
  }
    stopBubble(e)
}
function stopBubble(e) {
    if (e){
     e.stopPropagation();
   }
    else{

     window.event.cancelBubble = true;
  }
}
document.onclick = function(e){
    get("product_tips").style.display = "none";
  }
</script>
</head>
<body>
<div class="relative_">
<label><input type="text" name="#" value="" id="product_name" maxlength="6" /></label>&nbsp;&nbsp;<span id="help">help ?</span>
        <div id="product_tips" class="product_tips" style="display:none;">
          <div class="product_inbox">
            <p>content content content content content content content content content content content content content content content content content content content content </p>
          </div>
        </div>
        </div>
  <script type="text/javascript">
      get('help').onclick = showTip;
      get('product_tips').onclick = stopBubble;
    </script>
</body>
<html>

javascript cancelBubble在Firefox上不起作用
