Question

如何在js中使用json格式，有一json格式的数据，不知如何使用

var prd={"skuMap":{"2744825;24447243":{"color":"\u4f9d\u7136\u98ce\u91c7","size":"200x230cm","stock":"198"},"2744829;24447247":{"color":"\u7f8e\u5999\u82b1\u9999","size":"200x230cm","stock":"165"}}};

var stu = "2744825;24447243"; //该字符串是动态拼接得到的
请问我如何调用该数据，能得到2744825;24447243中的stock项？使用prd.skuMap[stu].stock没用

Answer 1

不确定的话可以遍历啊,用如下代码编历即可
for(var p in prd.skuMap){
alert(prd.skuMap[p]['stock']);
}

追问

这样遍历也得不到结果，会不会是数据prd有问题？

你在开玩笑吧?

var prd={"skuMap":{"2744825;24447243":{"color":"\u4f9d\u7136\u98ce\u91c7","size":"200x230cm","stock":"198"},"2744829;24447247":{"color":"\u7f8e\u5999\u82b1\u9999","size":"200x230cm","stock":"165"}}};
for(var p in prd.skuMap){
alert(prd.skuMap[p]['stock']);
}

Answer 2

var prd={"skuMap":{"2744825;24447243":{"color":"\u4f9d\u7136\u98ce\u91c7","size":"200x230cm","stock":"198"},"2744829;24447247":{"color":"\u7f8e\u5999\u82b1\u9999","size":"200x230cm","stock":"165"}}};

alert( prd['skuMap']['2744825;24447243']['stock']);
