微信小程序判断对象组是否包含某对象

查了好久才查到！！！！

判断的时候一定要用JSON.stringify()

var list=that.data.list;
if(list.length != 0){
for(var i=0;i<res.data.limitTask.length;i++){
console.log( list.indexOf(res.data.limitTask[i]))
//判断是否存在此对象 -1 不存在
if(JSON.stringify(list).indexOf(JSON.stringify(res.data.limitTask[i])) == -1){
list=list.concat(res.data.limitTask[i])
}
}
}else{
list=list.concat(res.data.limitTask);
}

            console.log(list)
