jQuery AJAX调用PHP控制器 [英] jQuery AJAX call to PHP Controller

问题描述

我通过jQuery调用一个控制器（Codeigniter）。我的dataString变量包含一个简单的字符串，我试图通过我的控制器，所以我可以将它传递给模型。但是，我收到一个错误，指出我的$ test_var是未定义的。我做错了什么？

I am calling a controller (Codeigniter) through jQuery. My dataString variable contains a simple string, which I'm trying to pass through to my controller, so I can pass it into the model. However, I'm getting an error that indicates that my $test_var is undefined. What am I doing wrong?

$('a.test').click(function (event) {


    dataString = $(this).attr('name'); 
        $.ajax({
        type:"POST",
        url:"<?php echo base_url(); ?>controller_name/",
        data:dataString,
        success:function (data) {
        alert('test');
        }

    });
    event.preventDefault();
});

controller

$ test_var = $ this-> input-> post（'dataString'）;

$test_var= $this->input->post('dataString');

推荐答案

尝试使用名称=值对：

Try using a name=value pair:

$('a.test').click(function (event) {


    dataString = $(this).attr('name'); 
        $.ajax({
        type:"POST",
        url:"<?php echo base_url(); ?>controller_name/",
        data:'dataString='+dataString,
        success:function (data) {
        alert('test');
        }

    });
    event.preventDefault();
});
