Submit the form by clicking links without using the submit button

I am trying to submit a form by clicking links without using a submit button. Each form element has its own value that must be submitted when clicked. This does not work. I could use JavaScript or jQuery. Please take a look at the code:

<head>
  <style>
  div {
    width: 100px;
    height: 100px;
    padding: 10px;
    margin: 10px;
    background-color: #EEEEEE;
  }
</style>
</head>
<body>
<form name="myform" action="test.php" method="post">
<div>
<a href="javascript: submitform()" value='h1'>h1</a><br>
<a href="javascript: submitform()" value='h2'>h2</a><br>
<a href="javascript: submitform()" value='h3'>h3</a><br>
</div>
</form>
<script type="text/javascript">
function submitform()
{
  document.myform.submit();
}
</script>
<div>
<?php
$form=$_POST['myform'];
echo $form.' bla<br>';
?> 
</div>
</body>
</html>

with suggestions for a baruch!

<head>
<script src="jquery.js" type="text/javascript"></script>
  <style>
  div {
    width: 100px;
    height: 100px;
    padding: 10px;
    margin: 10px;
    background-color: #EEEEEE;
  }
</style>
</head>
<body>
<form name="myform" action="test.php" method="post">
<input type='hidden' id='hx' name='hx' value=''>

<div>
<a href="javascript: submitform('h1')">h1</a><br>
<a href="javascript: submitform('h2')">h2</a><br>
<a href="javascript: submitform('h3')">h3</a><br>
</div>
</form>
<script type="text/javascript">
function submitform(val)
{
  $("#hx").val(val);
  document.myform.submit();
}
</script>
<div>
<?php
echo $_POST['hx'];
?> 
</div>
</body>
</html>

Add the following line after <form...>

:

<input type='hidden' id='hx' name='hx' value=''>

Then change your calling function to:

<a href="javascript: submitform('h1')">h1</a><br>

Your function:

<script type="text/javascript">
function submitform(val)
{
  $("#hx").val(val);
  document.myform.submit();
}
</script>

in your php:



echo $_POST['hx'];

How it works?

1.You click the link

2. The js function changes the value of the HIDDEN INPUT field

3. The js function submits the form

4. $ _ POST refers to a hidden input value

First, I wouldn't use href="javascript:submitForm();"

, instead usehref="#" onclick="submitForm(this)"

Add a hidden field to your form

<input type="hidden" value="" id="hiddenId" />


In the submitForm method, change myform to forms [0]. I believe this will be more browser friendly. Anywho ... add a parameter to your method so you can set the value of the hidden field.

<script type="text/javascript"> 
function submitform(el) 
{   
  document.getElementById('hiddenId').value = el.value;
  document.forms[0].submit(el); 
} 
</script>
