我有这个表格将POST到show_aht2.php，但我也希望它能够进行下面我的代码中看到的AJAX调用。那么，我怎么能这样做，所以用户不去另一个？我希望用户留在map.php
提前致谢
map.php
<form action="show_aht2.php" method="post">
<input type="radio" name="date_selected" value="1d" checked="checked"/>1d
<input type="radio" name="date_selected" value="1w" />1w
<input type="radio" name="date_selected" value="1m" />1m
<input type="radio" name="date_selected" value="3m" />3m
<input type="submit" id="aht_btn" name="get_aht" value="Get AHT" />
</form>
<script type="text/javascript">
$(document).ready(function() {
$('#aht_btn').click(function(){
$.ajax({
type:"GET",
url : "show_aht2.php",

dataType: 'json',
success : function(data){

首先执行ajax调用，然后使用.submit（）稍后使用ajax的回调提交表单。
<form action="show_aht2.php" method="post" id="formtopost">
<script type="text/javascript">
$(document).ready(function() {
$('#aht_btn').click(function(){
$.ajax({
type:"GET",
url : "show_aht2.php",
data:{ } , // do I need to pass data if im GET ting?
dataType: 'json',
success : function(data){
//doing stuff
//end success
},
always: function() {
//submit form !!!
$("#formtopost").submit();
}
});//end ajax
});//end click
});//end rdy
</script>

尝试：
<script type="text/javascript">
$(document).ready(function() {
$('#aht_btn').click(function(event){
event.preventDefault();
$.ajax({
type:"GET",
url : "show_aht2.php",
data:{ } , // do I need to pass data if im GET ting?
dataType: 'json',
success : function(data){
//doing stuff
}//end success
});//end ajax
});//end click
});//end rdy
</script>
使用方法preventDefault：http://api.jquery.com/event.preventdefault/

您可以使用ajax提交表单，而不是同时尝试同时执行这两项操作
这样的事可能吗？
<script type="text/javascript">
$(document).ready(function() {
$('#aht_btn').click(function(){
// This prevents the form from submitting
event.preventDefault();
// Capture form input
var $form = $(this);
var serializedData = $form.serialize();
// Run the ajax post
$.ajax({
url : "show_aht2.php",
type:"POST",
data: serializedData
success: function(response) {
// Do something
}
});
});//end click
});//end rdy
</script>
