json - 如何使用prototype.js解析json数据并遍历它？

Question

我有json数组

var data = '[{ "name": "Violet", "occupation": "character" },{ "name": "orange", "occupation": "color" }]'

如何使用prototype.js解析数据并遍历它？

Answer 1

有一个函数叫 evalJSON()

var data = '[{ "name": "Violet", "occupation": "character" },{ "name": "orange", "occupation": "color" }]';
data = data.evalJSON();
//for more security:
data = data.evalJSON(true); //sanitizes data before processing it

然后只需使用 for遍历数组:

for (var i=0;i<data.length;i++)
{ 
    //do whatever you like with data[i];
}

或者使用prototypeJS .each()功能:

data.each(function(el){
    //do whatever you like with el
});
