输入保存到一个文件，然后提交到URL上提交

Question

我有一个表单。现在它只有一个动作，只是将输入提交给URL。我希望在表单完成时将输入保存到文件中，然后提交到URL。

<form class="snp-subscribeform snp_subscribeform" action="join.cgi" method="post"> 
    <input name="page" type="hidden" value="1" /> 
    <div> 
     <input id="snp-firstname" class="snp-field snp-field-firstname " name="firstname" required="" type="text" value="" placeholder="Enter Your First Name" /> 
     <input id="snp-lastname" class="snp-field snp-field-lastname " name="lastname" required="" type="text" value="" placeholder="Enter Your Last Name" /> 
     <input id="snp_email" class="snp-field snp-field-email" name="email" type="text" placeholder="Enter Your Email " /> 
     <input id="snp-password" class="snp-field snp-field-password " name="password" required="" type="text" value="" placeholder="Select A Password" /> 
    </div> 
    <div> 
     <input class="snp-subscribe-button snp-submit" type="submit" value="CONTINUE" data-loading="Creating Account!" data-success="Account Created!" /> 
    </div> 
</form> 
</div>

你可能会需要使用javascript和onclick事件提交按钮，从DOM元素你有兴趣在获取值，并将其保存到文件中。

这里是如何开始一个示例：

<input type="submit" name="submit" value="Save" onclick="writedata()" /> 

<script> 
    function writeData() { 
    } 
</script>
