直指高手，力求帮助。 取一段json的对象的组名~ [问题点数:35分]

[Leo_0924]

我要取一段json像这样的json


也就是说，一段json字符串，类似结构为
{ "options ": "[{\ "text\ ":\ "王家湾\ ",\ "value\ ":\ "9\ "},
{\ "text\ ":\ "李家湾\ ",\ "valu e\ ":\ "10\ "},
{\ "text\ ":\ "邵家湾\ ",\ "value\ ":\ "13\ "}] "}
我想取得options，这个字符串！

大家谁知道的么？

[Leo_0924]

没人知道吗？还是没人想知道？还是根本没办法？

[liherun]

不会JSON
如果是字符串的话用正则可以得到

[zorou_fatal]

使用.NET Framwork3.5自带的System.Runtime.Serialization.Json

var people =
  {   "authors": [
    { "firstName": "Isaac", "lastName": "Asimov", "genre": "science fiction" },
    { "firstName": "Tad", "lastName": "Williams", "genre": "fantasy" },
    { "firstName": "Frank", "lastName": "Peretti", "genre": "christian fiction" }
   ]
  }



//取值：
people.authors[1].genre	值为  fantasy

自己按照此方式推一下就知道了

var jsonValue={ "options ": "[{\ "text\ ":\ "王家湾\ ",\ "value\ ":\ "9\ "},
{\ "text\ ":\ "李家湾\ ",\ "valu e\ ":\ "10\ "},
{\ "text\ ":\ "邵家湾\ ",\ "value\ ":\ "13\ "}] "}


var stringName=josnValue.options[1].text;就是‘李家湾’

[Leo_0924]

var jsonValue={ "options ": "[{\ "text\ ":\ "王家湾\ ",\ "value\ ":\ "9\ "},
{\ "text\ ":\ "李家湾\ ",\ "valu e\ ":\ "10\ "},
{\ "text\ ":\ "邵家湾\ ",\ "value\ ":\ "13\ "}] "}


我要得到options .....

var options = eval(jsonValue.options); 就是你想要的呀
这样添加到select元素里面：
for(var i=0; i<options.length;i++)
{
var varItem = new Option(options[i].text, options[i].value);
select.options.add(varItem);
}

[Leo_0924]

我不确定options 就是options ，因为他是随时会变得啊！

var jsonValue={ "会变的options ": "[{\ "text\ ":\ "王家湾\ ",\ "value\ ":\ "9\ "},
{\ "text\ ":\ "李家湾\ ",\ "valu e\ ":\ "10\ "},
{\ "text\ ":\ "邵家湾\ ",\ "value\ ":\ "13\ "}] "}

[itliyi]

$.ajax({
           url: "xxx.ashx",
           dataType: "json",
           //data: "type=getRoleList",
           type: "GET",
           error: function() { },
           beforeSend: function() { $("#lbltest").html("正在加载，请稍后..."); },
           success: function(data) {
           if (data.options.length == 0) {
                 alert("禁止操作！");
                        document.getElementById("btnSave").disabled = "disabled";
            }
           else{
                 $.each(data.options, function(index, value) {
                        var option = new Option(value.text, value.value);
                        document.getElementById("lstRole").add(option);
                 });
           }
          }
}); <select id="lstRole" style="width:150px"></select>

兄弟会变总得有个规律吧，有规律同样循环啊
