现在,我只加载了一个页面(load.php?cid=1,但我想在不同的div中加载5-8 (cid=1、cid=2、cid=3、cid=4、cid=5、cid=6、cid=10 ...etc ))。
我将如何实现这一目标?
$(document).ready(function() {
function loading_show() {
$('#loading_Paging').html("<img src='images/loading.gif'/>").fadeIn('fast');
}
function loading_hide() {
$('#loading_Paging').fadeOut 'fast');
}
function loadData(page) {
loading_show();
$.ajax({
type: "POST",
url: "load.php?cid=1",
data: "page=" + page,
success: function(msg) {
$("#container_Paging").ajaxComplete(function(event, request, settings) {
loading_hide();
$("#container_Paging").html(msg);
});
}
});

正如JimL所暗示的,我将为页面上的每个元素提供一个公共类,为每个元素提供一个惟一的数据属性(如data-cid="1" ),迭代每个获取cids的元素并为每个元素调用ajax函数。
Id更进一步,使用承诺获取所有ajax响应,然后在承诺被解析后加载所有数据(当所有ajax请求都完成时)。
这是一个有用的例子
HTML:
<div id="loading_Paging"></div>
<div class="myElements" data-cid="1"></div>
<div class="myElements" data-cid="2" ></div>
<div class="myElements" data-cid="3" ></div>
<div class="myElements" data-cid="4" ></div>
<div class="myElements" data-cid="5" ></div>
<div class="myElements" data-cid="6" ></div>
<div class="myElements" data-cid="7"></div>
<div class="myElements" data-cid="8" ></div>The jQuery:
$(function() {
var page = 'some string...'
loadData(page);
function loadData(){
$('#loading_Paging').html("<img src='images/loading.gif'/>").fadeIn('fast');
// loop through each image element
// calling the ajax function for each and storing the reponses in a `promise`
var promises = $('.myElements').map(function(index, element) {
var cid = '&&cid=' + $(this).data('cid'); // get the cid attribute
return $.ajax({
type: "POST",
url: 'load.php',
data: "page=" + page +cid, //add the cid info to the post data
success: function(msg) {
}
});
});
// once all of the ajax calls have returned, te promise is resolved
// and the below function is called
$.when.apply($, promises).then(function() {
// arguments[0][0] is first result
// arguments[1][0] is second result and so on
for (var i = 0; i < arguments.length; i++) {
$('.myElements').eq(i).html( arguments[i][0] );
}
$('#loading_Paging').fadeOut('fast');
});
}
});我在我的示例中使用的PHP:
<?php
if (isset($_POST['cid']) ){
// this is just a contrived example
// in your code youd use the cid to
// get whatever data you need for the current div
echo 'This is returned message '.$_POST['cid'];
}
