jquery 遍歷json中的問題。

Question

json如下：
{"npcs":[{"id":1,"map":{"mapFile":"map1.jpg","mapId":1,"mapName":"沒有地圖"},"name":"牛牛1号","pos1x":80831.66,"pos1y":9817.49,"pos1z":78168.51,"template":{"armorClass":10,"attPower":10,"block":10,"chaseRange":1000,"creatureType":2,"crit":100,"defMagic":10,"dodge":80,"hit":10,"hp":799,"id":2,"mp":230,"name":"褐色蝎子","parry":10,"spellPower":10,"visiableRange":600}}]}

要如何得到子集合 map , template中的值？

如果是用.each的話，會對所有的字段都進行遍歷，但是僅僅是map ,template才是集合。

Answer 1

var s = {"npcs":[{"id":1,"map":{"mapFile":"map1.jpg","mapId":1,"mapName":"沒有地圖"},"name":"牛牛1 号","pos1x":80831.66,"pos1y":9817.49,"pos1z":78168.51,"template": {"armorClass":10,"attPower":10,"block":10,"chaseRange":1000,"creatureType":2,"crit":100,"defMagic":10,"dodge":80,"hit":10,"hp":799,"id":2,"mp":230,"name":" 褐色蝎子","parry":10,"spellPower":10,"visiableRange":600}}]} ;

var npcs = obj.npcs;
var map = npcs[0].map;
var template = npcs[0].template;

// 取值
var mapFile = map.mapFile;
var armorClass = template.armorClass;

上面那个多转了一下。
