<div class="people-state" οnclick="toFollow({$vo['follow_user_id']})">+关注</div>
</div>
function toFollow(follow_user_id) {
console.log(event);
var toUrl = "{:url('index/follow/toFollow')}";
var postData = {follow_user_id:follow_user_id};
$.post(
toUrl,
postData,
function (result) {
if(result.code == 0){
target.outerHTML = "<div class=\"people-state active\" οnclick=\"toFollow("+follow_user_id+")\">取消关注</div>";
