全局变量未在ajax调用中显示结果 [英] Global variable is not showing result inside a ajax call

问题描述

大家好

这里的index是一个全局变量.我正在另一个函数中操作索引.

之后，我调用此函数.它在ajax调用之后和之后显示实际结果，但在ajax调用内部未显示.

Hi all

Here index is a global variable. I am manipulating the index in another function.

After that I call this function. its showing the actual result outside and after the ajax call but not showing inside the ajax call.

var urlSearch = "http://192.168.10.113/collective-intellegence/UserClickPersonClassifier?userid=1&query=asp.net";
alert(index);
$.ajax({
    url: urlSearch,
    type: 'POST',
    dataType: 'json',
    success: function (data) {
        alert(index);
    }
});

我有做错什么吗?

请帮助解决此问题.

在此先感谢您.

Is there any mistake done by me.

Please help to solve this problem.

Thanks in advance.

推荐答案

.ajax({ url:urlSearch， 类型:' POST'， dataType:' json'， 成功:功能(数据){ 警报(索引); } });

.ajax({ url: urlSearch, type: 'POST', dataType: 'json', success: function (data) { alert(index); } });

如果看不到全局变量，则可以创建本地副本，如var i = index;.并在您的AJAX回调中访问i.如果这不是一个奇怪的范围问题，那么您未向我们展示的代码就有问题.

If it can''t see a global, you could create a local copy as in, var i = index; and access i inside your AJAX callback. If it''s not a weird scoping issue, then there''s an issue with the code you''ve not shown us.
