Question

我有一个Ionic应用程序，我正在搜索用户。当搜索返回结果时，我希望能够关注或取消关注该用户。

 //search
$scope.searchPro = function(){
var query = new Parse.Query(Parse.User);
var searchinpu = $('#search-input').val();
var searchinput = searchinpu.toLowerCase();
query.equalTo("username", searchinput);  // find all the relative users

query.find({
  success: function(results) {
    //Return User and foreach loop
    var searchcon = "";
    for (var i in results){
            var username = results[i].get("username");
            var image = results[i].get("profile_pic");
            var postimage = image.url();
            var curUser = Parse.User.current();
             //Second Query get follow button
            var cquery = new Parse.Query(Activity);
            cquery.matches("fromUser", curUser);  // find if he or she follows or not
            cquery.matches("toUser", username);  // find if he or she follows or not
            cquery.find();

            var button = "<button class='button button-outline button-lighter follow'>Follow</button>";
            searchcon += "<div class='search-re'>";
            searchcon += "<div class='search-re-view'><img src="+postimage+"></img></div>";
            searchcon += "<div class='search-re-small'><img src="+postimage+"></img></div>";
            searchcon += "<h3>@"+username+"</h3>";
            searchcon += button;
            searchcon += "</div>";
        }

搜索用户并返回结果正常。问题是第二个查询。我无法检查当前用户是否跟踪了搜索到的用户。因此，我无法区分按钮应该是跟随按钮还是取消跟随按钮。有没有办法显示这个按钮？

如何使用解析在for循环中查询？
