HTML Form submit data
Question
I have a form on a remote server I'm trying to submit data to, example below
<html>
<head>
</head>
<form action="http://www.example.com/post.php" method="post">
<input type="text" name="input1" value="test1" />
<input type="text" name="input2" value="test2" />
<input type="submit" name="send" value="Submit" />
</form>
</body>
</html>
I'm trying to auto submit the data like this
<html>
<head>
</head>
<form action="http://www.example.com/post.php" method="post">
<input type="text" name="input1" value="test1" />
<input type="text" name="input2" value="test2" />
<script type="text/javascript">
document.forms[0].submit();
</script>
</form>
</body>
</html>
It works fine if the first example didn't have a (name="send") name but when it does have a name nothing submits. My question is how would I go about sending the data with a input button that has a name.
Thank you

Note: The answer turned out to be type="hidden" instead of type="submit" , in which the second does not allow DOM submission while also submitting that input 's value in the GET/POST data. type="hidden" does, and it works here since the button does not need to be physically clicked.
Pick one:
<form name="formname" id="formid" action="http://www.example.com/post.php" method="post">
<input type="text" name="input1" value="test1" />
<input type="text" name="input2" value="test2" />
<input type="submit" name="send" value="Submit" />
</form>
<script type="text/javascript">
if (confirm('Ok for "formname", Cancel for "getElementById"')) {
console.log('document.formname.submit()');
document.formname.submit();
} else {
console.log('document.getElementById("formid").submit()');
document.getElementById('formid').submit();
}
</script>

Your JavaScript code will get executed as soon as the page is loaded. That is why it gets submitted immediately.
You need to wrap the JS code in a function and let an event call it from the page.
You can use a regular button and set the function for the onclick event of a button.
<html>
<head>
<body>
<form action="http://www.example.com/post.php" method="post">
<input type="text" name="input1" value="test1" />
<input type="text" name="input2" value="test2" />
<input type="button" name="send" value="test2" onclick="doSubmit()" />
<script type="text/javascript">
function doSubmit() {
document.forms[0].submit();
}
</script>
</form>
</body>
</html>
