使用JavaScript自动提交表单 [英] Auto-Submit Form using JavaScript

问题描述

 < form name =myFormid =myFormaction =test.phpmethod =POST> 
< p> 
< input name =testvalue =test/> 
< / p> 
< p> 
< input type =submitname =submitvalue =Submit/> 
< / p> 
< / form> 
 
< script> 
 
 var auto_refresh = setInterval（
 function（）
 {
 submitform（）; 
}，10000）; 
 
函数submitform（）
 {
 alert（'test'）; 
 document.myForm.submit（）; 
} 
< / script> 
  

我无法每隔 10秒自动提交表单 曾登陆网页。表单名称是myForm action =test.php。我收到了'test'的消息，但该页面没有提交表单。

除了自动加载函数在页面加载？

FIXED：已删除（ name =submit）从提交按钮开始，它运行得很顺利。

解决方案

你需要指定一个框架，否则你的脚本会在首次提交时消失！

用文档更改 document.myForm 。 forms [myForm] ：

 < form name =myFormid =myForm target =_ myFrameaction =test.phpmethod =POST> 
< p> 
< input name =testvalue =test/> 
< / p> 
< p> 
< input type =submitvalue =Submit/> 
< / p> 
< / form> 
 
< script type =text / javascript> 
 window.onload = function（）{
 var auto = setTimeout（function（）{autoRefresh（）;}，100）; 
 
函数submitform（）{
 alert（'test'）; 
 document.forms [myForm]。submit（）; 
} 
 
函数autoRefresh（）{
 clearTimeout（auto）; 
 auto = setTimeout（function（）{submitform（）; autoRefresh（）;}，10000）; 
} 
} 
< / script> 
  

<form name="myForm" id="myForm" action="test.php" method="POST">
  <p>
  <input name="test" value="test" />
  </p>
  <p>
    <input type="submit" name="submit" value="Submit" />
  </p>
</form>

    <script>

    var auto_refresh = setInterval(
    function()
    {
    submitform();
    }, 10000);

    function submitform()
    {
      alert('test');
      document.myForm.submit();
    }
    </script>

I'm having trouble trying to auto-submit a form every 10 seconds once landed on a page. The form name is myForm action="test.php". I get the 'test' message but the page doesn't submit the form.

Any solutions besides autoloading the function upon page load?

FIXED: Removed (name="submit") from the submit button and it worked smoothly.

解决方案

You need to specify a frame, a target otherwise your script will vanish on first submit!

Change document.myForm with document.forms["myForm"]:

<form name="myForm" id="myForm" target="_myFrame" action="test.php" method="POST">
    <p>
        <input name="test" value="test" />
    </p>
    <p>
        <input type="submit" value="Submit" />
    </p>
</form>

<script type="text/javascript">
    window.onload=function(){
        var auto = setTimeout(function(){ autoRefresh(); }, 100);

        function submitform(){
          alert('test');
          document.forms["myForm"].submit();
        }

        function autoRefresh(){
           clearTimeout(auto);
           auto = setTimeout(function(){ submitform(); autoRefresh(); }, 10000);
        }
    }
</script>
