Php Ajax-一个页面中的多个调用

现在我的代码只加载1页（load.php？cid=1，但我想在不同的div中加载5-8页（cid=1，cid=2，cid=3，cid=4，cid=5，cid=6，cid=10…等等）

$(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);
                    });
                }
            });
        }

我将如何实现它

$(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);
                    });
                }
            });
        }

$（文档）.ready（函数（）{
函数加载_show（）{
$（'#加载分页'）.html（“”.fadeIn（'fast'）；
}
函数加载_hide（）{
$（“#加载#分页”）.fadeOut“fast”）；
}
函数加载数据（第页）{
加载_show（）；
$.ajax({
类型：“POST”，
url:“load.php？cid=1”，
数据：“第页=”+第页，
成功：功能（msg）{
$（“#容器#分页”）.ajaxComplete（函数（事件、请求、设置）{
加载_hide（）；
$（“#容器分页”）.html（msg）；
});
}
});
}

正如JimL所提到的，我会给页面上的每个元素一个公共类，给每个元素一个唯一的数据属性，比如

data cid=“1”

，遍历每个元素，获取cid并为每个元素调用ajax函数

$(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);
                    });
                }
            });
        }

我更进一步，使用承诺获取所有ajax响应，然后在承诺得到解决（当所有ajax请求完成时）加载所有数据

$(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);
                    });
                }
            });
        }

这是

$(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);
                    });
                }
            });
        }

HTML:

$(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({

                        loading_hide();
                        $("#container_Paging").html(msg);

我在示例中使用的PHP:

        function loadData(page) {
            loading_show();
            $.ajax({
                type: "POST",
                url: "load.php?cid=1",

“最简单”的解决方案是只复制您正在执行的jquery ajax调用。为了更简洁，您可以对要加载的div使用一些巧妙的命名，对它们进行迭代并执行适当的ajax调用。即给每个“空”div一个可加载（或类似）的类，并给它一个类似于data cid=“x”的属性。然后选择所有$（'.loadable'），并为每一个执行一次ajax with cid=data cid。我在下面留下了完整的答案，但仅供参考，在您的原始代码中，您缺少了一个

（
.fadeOut'fast'）；
和
）最后（尽管第二个可能刚刚从您的复制/粘贴中被遗漏），这里的问题是我不能发布完整的代码。
