Question

我正在使用jQuery ajax()函数进行ajax调用。我一直收到错误：

SyntaxError：意外的令牌＆lt;

这是我的功能：

function testAjax(subject)
{    
$.ajax({
        url: '/profile/testAjax',
        type: 'GET',
        data: { field1: subject} ,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
        //your success code
        alert(response);
        },
        error: function (xhr, ajaxOptions, thrownError) {
        alert("Error: " + thrownError);
     }
    }); 
}

在我的控制器中，testAjax功能如下：

public function testAjax($subject)
{
    return "This works:" . $subject;
}

此处调用该函数：

$(document).on('click', '#applyButton', function(e) 
{
e.preventDefault();
testAjax($(this).val()) 
});

任何人都知道我为什么会这样做？我知道这可能与contentType和dataType。

有关
