<script>
var bln = window.confirm("确定吗?");
alert(bln)
</script>
或者
直接这样写<input name="Submit" type="submit" class="button1" value="确认" onclick="javascript:window.confirm("确认提交？")>
无论点确定还是取消都是提交。请问该怎么做才能在点取消时不会提交表单？
input name="Submit", 这个地方改成button
然后再这样
if(window.confirm("确认提交？"))
{
from.Submit();
}
在<form>加入onsubmit="javascript:return formcheck()"
在formcheck()中做window.confirm()
根据window.confirm的返回参数让formcheck()返回false或true
false不提交表单，true提交表单
也可用下面的方法，更简单：
<form name="form1" method="post" action="xxx.htm" onSubmit="javascript:return window.confirm('确认提交吗？')">
