这是我自己的页面的一个例子。
<?php
$do = $_GET['do'];
switch($do){
case 'finalTask':
if(isset($_POST['url'])){
echo "It's Ok!";
}else{
echo "Problem!";
}
}
这也写在同一页面上。
<input type='text' id='siteName'>
<button type='submit' id='send'>Send</button>
<div id='info'></div>
<script>
$(document).ready(function(e){
$('#send').click(function(){
var name = $('#siteName').val();
var dataStr = 'url=' + name;
$.ajax({
url:"index.php?do=finalTask",
cache:false,
data:dataStr,
type:"POST",
success:function(data){
$('#info').html(data);
}
});
});
});
</script>
当我尝试输入并按下发送按钮时。什么都没发生.....代码有什么问题?

您的页面中似乎没有表单,只是表单元素。你能用一种形式包装它们:
<form method="POST" onSubmit="return false;">
<input type='text' id='siteName'>
<button type='submit' id='send'>Send</button>
</form>

<?php
if (!isset($_GET['do'])) { // Make sure that you don't get the form twice after submitting the data
?>
<input type='text' id='siteName'>
<button type='submit' id='send'>Send</button>
<div id='info'></div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$(document).ready(function (e) {
$('#send').click(function () {
var name = $('#siteName').val();
var dataStr = 'url=' + name;
$.ajax({
url: "index.php?do=finalTask",
cache: false,
data: {url: dataStr}, // you need to send as name:value format.
type: "POST",
success: function (data) {
$('#info').html(data);
}
});
});
});
</script>
<?php
} else {
error_reporting(E_ERROR); // Disable warning and enable only error reports.
$do = $_GET['do'];
switch ($do) {
case 'finalTask':
if (isset($_POST['url'])) {
echo "It's Ok!";
} else {
echo "Problem!";
}
}
}
?>
