返回Jquery ajax数据但不调用success函数

标签： javascript jquery ajax

我有以下ajax：

   $.ajax({
        type: 'POST',
        url: '/Module/findByType',
        dataType: 'json',
        data: {
            request: 'ajax',
            type_id: id
        },
        success: function (data)
        {
            var i = 0;
        })

这将生成以下输出：

我可以从chrome中的开发人员工具中看到。

然而，永远不会调用成功函数。

有人可以看到问题所在吗？

更新

好的就是：

我有两个ajax调用取决于type_id，所以这是我非常复杂的PHP代码：

        public function findByType()
    {

        if ($_SESSION['User']['type'] <= 2) {
            if(isset($_POST['type_id']))
            {
                $organization_modules = $this->getDatabase()->template('
          SELECT Module.*, MT.name as type_name, MT.color as type_color, C.name as category_name, C.image_path as image_path, C.color FROM module Module
           INNER JOIN organization_has_module OHOM
           ON Module.id = OHOM.Module_id JOIN category C ON C.id = Module.category_id INNER JOIN module_type MT on MT.id = Module.module_type

                $all_modules = $this->getDatabase()->template('SELECT

            else
            {
                $organization_modules = $this->getDatabase()->template('

            }
        }

        print json_encode($all_modules);
    }

当我用id 9调用它时，我得到上面的json并且不调用success函数。

当我用id 4调用这个函数时，我得到以下json：

答案 0 :(得分：1)

尝试在你的ajax代码上使用async：false，默认情况下async为true，这是它的例子

$。AJAX（{

type: 'POST',
url: '/Module/findByType',
dataType: 'json',
async : false,
data: {
    request: 'ajax',
    type_id: id
},
success: function (data)
{
    var i = 0;
    console.log("Value of i:" + i);
    console.log("Result:" + data);
})

答案 1 :(得分：0)

我怀疑你会在i函数之后使用success的值。但由于请求是异步的并且您同步读取i的值，因此您可能无法获得最终值，因为JavaScript在AJAX调用之前执行命令。

可能你可以做到这一点。您可以使用alert()而不是console.log()来检查函数是否正在执行。这是正确的方法。

我的建议是将AJAX调用后使用i值的代码放入函数中，并在AJAX调用的success函数中调用该函数。

答案 2 :(得分：0)

我猜代码没有问题，你只需提醒/ console.log里面的数据成功，请看下面的示例，

$.ajax({

    type: 'POST',
    url: '/Module/findByType',
    dataType: 'json',
    data: {
        request: 'ajax',
        type_id: id
    },
    success: function (data)
    {
        var i = 0;
        console.log("Value of i:" + i);
        console.log("Result:" + data);
    })
