var pointValue = "118.686649";
var pointContent = "";
var Point = null;
//根据point找到DATA[i]，再找到它的content
for(var i=0;i<DATA.length;i++){
if(DATA[i].point==pointValue){
Point = DATA[i];
pointContent=Point.content;
}
}追问
var pointContent = "";
var Point = null;
//根据point找到DATA[i]，再找到它的content
for(var i=0;i<DATA.length;i++){
if(DATA[i].point==pointValue){
Point = DATA[i];
pointContent=Point.content;
}
}追问
我的还是找不到，弹出的是空白
追答你的point改一下，我的是测试数据，你改成var pointValue = "118.686649|35.674655";
