单位的项目，使用了json来传递数据，IE7+是没问题的，不知道哪个用户竟然还使用IE6,悲催的报错了，现在要修改，请教各位大大方法。使用的是jquery 和 jquery.json.js
var str=JSON.stringify($(".txtAddOddts").val()); //将JSON对象转化为JSON字符串
现在需要把Json对象转换为字符串来供后台代码使用，但这句在IE6下使用不了百度了好多，都只是用json.js来转换的，不知道iE6中怎么解决。请教各位大大帮忙，开发工具vs2005

我查到的方法都是用json.js来帮忙转
我之前用的IE7+有用的语句是
var str=$.toJSONString($(".txtAddOddts").val()); // 将JSON对象转化为JSON字符顶楼的是我后来试的方法，没用
楼主的那个json前台转换有问题 我们可以采取后台转换 不必非得在前台转
但现在用户说IE6有问题，我测了下果然是
我之前用json.js 转换的方法也是从网上搜的
难道是这个js文件不支持ie6？
var str=$.toJSONString($(".txtAddOddts").val()); // 将JSON对象转化为JSON字符
这句话能把json对象转为string？
(".txtAddOddts").val()取出来的值就是个string类型的啊？所以 我想先问LZ是前台要把string转json还是json转string?
https://raw.github.com/douglascrockford/JSON-js/master/json2.js用法：
<script src="./json2.js"></script>
<script>
var test = {
testObj: [
{a:'b', c:'d'},
{a:{b:'c'}, d:'e'},
{a:['b', 'c'], d:'e'}
]
};
console.log(JSON.stringify(test));
// output {"testObj":[{"a":"b","c":"d"},{"a":{"b":"c"},"d":"e"},{"a":["b","c"],"d":"e"}]}
</script>
array.toJSONString()
boolean.toJSONString()
date.toJSONString()
number.toJSONString()
object.toJSONString()
string.toJSONString()
就是吧 {XX：yy} 转换成 “{xx：yy}”
前者是json对象 alert弹出结果是[object] 后者alert弹出结果为“{xx：yy}”8楼
$(".txtAddOddts").val() 是一个Json对象
用alert得到的结果是 object9楼 11楼 我现在在公司，没办法上网，只能查百度快照和上csdn，所以下载不了。。
有没人贴段转换的代码或者什么。。12楼 我目前用的就是json.js 不过是jquery.json.js, JSON.stringify是我后来找的方法没用
json.js
2007-08-05 Public Domain This file adds these methods to JavaScript: array.toJSONString()
boolean.toJSONString()
date.toJSONString()
number.toJSONString()
object.toJSONString()
string.toJSONString()
These methods produce a JSON text from a JavaScript value.
It must not contain any cyclical references. Illegal values
will be excluded. The default conversion for dates is to an ISO string. You can
add a toJSONString method to any date object to get a different
representation. string.parseJSON(filter)
This method parses a JSON text to produce an object or
array. It can throw a SyntaxError exception. The optional filter parameter is a function which can filter and
transform the results. It receives each of the keys and values, and
its return value is used instead of the original value. If it
returns what it received, then structure is not modified. If it
returns undefined then the member is deleted. Example: // Parse the text. If a key contains the string 'date' then
// convert the value to a date. myData = text.parseJSON(function (key, value) {
return key.indexOf('date') >= 0 ? new Date(value) : value;
}); It is expected that these methods will formally become part of the
JavaScript Programming Language in the Fourth Edition of the
ECMAScript standard in 2008. This file will break programs with improper for..in loops. See

我知道json.js 和jquery.json.js 不一样
但是我的项目里面用到了 jquery.js 后json.js 是无效的，
只能用jquery.json.js
所以我引入了 jquery.json.js
但是IE7+是有效的
偏偏IE6无效
json.js就是将原始的json对象转换成字符串
如果再用json.js 就冲突了，json.js就是将原始的json对象转换成字符串这个就没有效果
你试过了？？我这里用的jq1.4.4和json.js没有冲突。
json.js只是给array， boolean， date， number， object， string增加了一个原型方法toJSONString除非你的jquery.json.js或者jqeury添加了这个原型方法，否则100%不会冲突
你百度下 “json.js和jquery冲突”就知道 冲突的不只我一个人。
而且我公司项目里的jquery版本貌似很低 估计是1.3或者以下的版本。。要不我弄个高点版本的jquery来试试看。。
json2.js和jquery一起用。
