js提交表单,我们可以使用document.getElementById("formid").submit()来实现。

提示框可以使用window.confirm来实现。

下面来看一下具体的代码:

<code>

<title>js表单提交前进行确认提示</title>
<script type="text/javascript">
function formSubmit()
{
     if (window.confirm("确定提交表单吗?")){
            document.getElementById("form1").submit();
     }
} 
</script>


<form id="form1" method="post" action="/abc.php">
First name: 
<input type="text" name="FirstName" value="wu" size="20">
<br>Last name: 
<input type="text" name="LastName" value="xiao" size="20">
<br>
<input type="button" value="使用js提示是否提交表单" onclick="formSubmit();">
</form> 

</code>
Copy after login

你可以复制本文章的代码到这里运行一把,马上去运行

小结:实现js 表单提交主要使用到js的submit()方法。实现提示是否提交表单主要使用到window.confirm()方法。
