JSON.parse 转换数据？

  • 772
$.ajax({
            url: "php/data.php",
            type: 'POST',
            data: {act: 'load', user: self.user_id},
            success: function (data) {  
                c(data)
                var data = JSON.parse(data);
                c(data)
                self.loader = false;
                self.cols = data;
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });

得到

[{"cn":"serial","dt":"varchar","c":""},{"cn":"series","dt":"int","c":""},{"cn":"season","dt":"int","c":""},{"cn":"url","dt":"varchar","c":""}]
    admin.js?1.0:2 
    (4) [Object, Object, Object, Object]
    0:Object
    c
    cn:"serial"
    dt:"int"

那些。varchar不知何故变成了int

    解析是jQuery这样JSON使用函数完成的parseJSON()：

    $.ajax({
    url: "php/data.php",
    type: 'POST',
    data: {act: 'load', user: self.user_id},
    success: function (data) {  
        .......
        .......
        var json_decode_data = jQuery.parseJSON(data);
        ........
        ........
    },
    error: function (jqXHR, textStatus, errorThrown) {
        alert(errorThrown);
    }
});

    这是一个解析示例：

    var obj = jQuery.parseJSON( '{ "name": "John" }' );
alert( obj.name === "John" );
