var row = userlist.insertRow(userlist.rows.length);
var col = row.insertCell(0);
col.innerHTML = " <input name= 'checkbox ' type= 'checkbox ' value= ' "+rowIndex+ " ' id= 'checkbox_ "+rowIndex+ " ' /> ";
col.setAttribute( "align ", "center ");
col = row.insertCell(1);
col.innerText = rowIndex;
col.setAttribute( "align ", "center ");
row.setAttribute( "id ", "row "+rowIndex);
row.setAttribute( "name ", "row "+rowIndex);
rowIndex++;
}
//清空电话列表
function clearlist(){
var p=0;
var ls_t=document.all( "userlist ");
while (p <userlist.rows.length){
if (document.getElementById( "checkbox_ "+p).checked==true){
ls_t.deleteRow(p);
p=0;
}else{
p++;
}
}
}
</script>
</head>
<body>
<input name= "add " type= "button " onclick= "AddOneLine( '未知 ') " value= "add "/>
<input name= "del " type= "button " value= "del " onclick= "clearlist() "/>
<div style= "overflow:auto; width:100%; height:220 ">
<table width= "750 " border= "0 " cellspacing= "0 " cellpadding= "0 " id= "userlist ">
<th width= "27 "> </th>
<th width= "102 "> </th>
<th width= "80 "> </th>
<th width= "67 "> </th>
<th width= "63 "> </th>
<th width= "85 "> </th>
<th width= "119 "> </th>
<th> </th>
</table>
</div>
</body>
</html>
上面这个页面想要做成当用户选中表中的checkbox后，按del按钮会删除所有选中的数据行，可是为什么会出错呢？请高手讲讲。
