Auto-Submit Form using JavaScript

javascriptforms

提问by Crys Ex

<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 secondsonce 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.

一旦登陆页面,我在尝试每10 秒自动提交一次表单时遇到问题。表单名称是 myForm action="test.php"。我收到'test'消息,但页面未提交表单。

Any solutions besides autoloading the function upon page load?

除了在页面加载时自动加载功能之外,还有其他解决方案吗?

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

修正:name="submit"从提交按钮中删除 ( ) 并且它工作顺利。

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

您需要指定一个框架,一个目标,否则您的脚本将在第一次提交时消失!

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

更改document.myFormdocument.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>

Try using document.getElementById("myForm")instead of document.myForm.

尝试使用document.getElementById("myForm")代替 document.myForm。

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

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

Try this,

尝试这个,

HtmlElement head = _windowManager.ActiveBrowser.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = _windowManager.ActiveBrowser.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
element.text = "window.onload = function() { document.forms[0].submit(); }";
head.AppendChild(scriptEl);
strAdditionalHeader = "";
_windowManager.ActiveBrowser.Document.InvokeScript("webBrowserControl");
