PHP的jQuery / AJAX执行无法正常工作
问题描述：
I am trying to use jQuery/AJAX to run a PHP file on a server. This PHP simply adds a row with some constants to a database. Here is my code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Submit Application</title>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript">
function doSomething() {
$.get("http://.../submitApp.php");
}
</script>
</head>
<body>
<form id="form1" name="form1" method="post" action="javascript:doSomething()">
<p>
<label for="programName"></label>
<input type="text" name="programName" id="programName" />
</p>
<p>
<label for="greQuant"></label>
<input type="text" name="greQuant" id="greQuant" />
</p>
<p>
<label for="greVerbal"></label>
<input type="text" name="greVerbal" id="greVerbal" />
</p>
<p>
<input type="submit" name="submitApp" id="submitApp" value="Submit" />
</p>
</form>
</body>
</html>
Upon pressing the submit button on the above form, nothing seems to happen. I should mention I am running this locally via DreamWeaver. I know for a fact that the code is reaching the JavaScript method and that the PHP code is functional. Anyone know what's wrong?

Use POST instead of GET to do this work.
function doSomething() {
var programName = $('#programName').val();
var greQuant = $('#greQuant').val();
var greVerbal = $('#greVerbal').val();
$.ajax({
type: "POST",
url: "submitApp.php", //URL that you call
data: { programName: programName, greQuant:greQuant, greVerbal:greVerbal } //var in post: var from js
}).done(function(msg) {
alert(msg);//change to something to indicate action
}
});
and with your php, handle like this
<?php
$programName = $_POST['programName'];
$greQuant = $_POST['greQuant'];
$greVerbal = $_POST['greVerbal'];
//do something important
?>
this is just a simple example, you need apply some security to this php code
