Question

var data={
    "def": [{
        type: "限时促销",
        price: "52.50",
        limitTime: "",
        channelkey: "",
        add: "",
        gift: "",
        cart: "true",
        amountRestriction: "",
        isStart: "false"
    }],
    ";20509:28315;1627207:28341;": [{
        type: "限时促销",
        price: "52.50",
        limitTime: "",
        channelkey: "",
        add: "",
        gift: "",
        cart: "true",
        amountRestriction: "",
        isStart: "false"
    }]
  };
 怎么能把def里的price提取出来

Answer 1

var data={    "def": [{        type: "限时促销",        price: "52.50",        limitTime: "",        channelkey: "",        add: "",        gift: "",        cart: "true",        amountRestriction: "",        isStart: "false"    }],    ";20509:28315;1627207:28341;": [{        type: "限时促销",        price: "52.50",        limitTime: "",        channelkey: "",        add: "",        gift: "",        cart: "true",        amountRestriction: "",        isStart: "false"    }]  };
  var price = [];
  for(var i=0,len=data.def.length;i<len;i++){
      price.push(data.def[0].price);
  }
  console.log(price)这么简单的问题自己研究一下呗。

Answer 2

var d=eval(data)
var price=[];
for(var i=0,len=d.length;i<len;i++)
{
   price.push(d[i].price);
}

Answer 3

修改一下 应该这样var d = eval(data);
    var prices = [];
    prices.push(d["def"][0].price);
    prices.push(d[";20509:28315;1627207:28341;"][0].price);

Answer 4

var data={  "def": [{      type: "限时促销",      price: "52.50",      limitTime: "",      channelkey: "",      add: "",      gift: "",      cart: "true",      amountRestriction: "",      isStart: "false"  }],  ";20509:28315;1627207:28341;": [{      type: "限时促销",      price: "52.50",      limitTime: "",      channelkey: "",      add: "",      gift: "",      cart: "true",      amountRestriction: "",      isStart: "false"  }]};
window.onload = function() {
    var max=data.def.length;
    while(max>0){
        max--;
        alert(data.def[max].price);
    }
};

Answer 5

for(var i=0;i<def.def.length;i++){
   alert(def.def[i].price);
}
