JS遍历HTML元素
最好给html数组加上id属性，然后使用document.all来进行遍历<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<SCRIPT type="text/javascript">
var objs = document.all['url'];
for(var i=0; i<objs.length; i++){
window.alert(objs.value);
}
</SCRIPT>
</head>
<body>
<form name="form1">
<input id = "url"name="url[]" type="text" value="url 1" size="60" />
<inputid = "url"name="url[]" type="text" value="" size="60" />
<input id = "url" name="url[]" type="text" value="url 3" size="60" />
</form>
</body>
</html>
<HTML>
<head>
<SCRIPT LANGUAGE="JavaScript">
//遍历表格的每行每列
function viewCell()
{
var count=1; //在表格中显示的内容
for (i=0; i < document.all.tbl.rows.length; i++) { //遍历每行
for (j=0; j < document.all.tbl.rows(i).cells.length; j++) { //遍历行中的每一列
document.all.tbl.rows(i).cells(j).innerText = count; //在单元格显示数值
count++;
}
}
alert(count);
}
</SCRIPT>
</head>
<BODY >
<TABLE id=tbl border=1 width="200">
<TR><TH>&nbsp;</TH><TH>&nbsp;</TH><TH>&nbsp;</TH><TH>&nbsp;</TH></TR>
<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
