首先我们先用html创建一个表单

<code class="language-html"><form action="feedback.php" method="post">
 Name:<input type="text" name="username" size="30">
 <br><br>
 Email:<input type="text" name="useraddr" size="30">
 <br><br>
 <textarea name="comments" cols="30" rows="5">
 </textarea><br>
 <input type="button" value="Send Form">
</form></code>
Copy after login

在这个表单中,我们没用使用submit,我们准备使用js来提交这个表单。首先介绍一下js提交表单的方法。

首先需要获取到form表单,然后使用js的submit()方法来提交表单到服务器。语法如下:

<code class="language-javascript">document.getElementById("formid").submit();</code>
Copy after login

完整的代码如下:

<code class="language-html"><script>
function formSubmit()
{
     document.getElementById("form1").submit();
} 
</script>
<form action="feedback.php" method="post" id="form1">
 Name:<input type="text" name="username" size="30">
 <br><br>
 Email:<input type="text" name="useraddr" size="30">
 <br><br>
 <textarea name="comments" cols="30" rows="5">
 </textarea><br>
 <input type="button" onclick="formSubmit();" value="Send Form">
</form></code>
Copy after login
