Question

我正在尝试创建一个调用api并获取用户数据的简单应用。当用户数据显示在页面上时，我想用用户名搜索用户。尝试了很多次，但它不起作用。有人可以帮忙吗？

var base = "https://api.twitch.tv/kraken/channels/";
var key = "myKey&callback";
var users = ["ESL_SC2", "OgamingSC2", "cretetion", "freecodecamp",
             "storbeck", "habathcx", "RobotCaleb", "noobs2ninjas",
             "TwinGalaxiesLive","MedryBW", "frontender007","Gronkh"];



$(document).ready(function(){
  requestData(users);
  searchUsers($("a"));

});

function requestData ( arr ) {
  arr.forEach ( function ( user ) {
    var url = base + user + '/?client_id=' + key + '&callback=?';
    $.getJSON(url, function ( json ) {
      
      displayChannel(json);
      
    });
  });
}

function displayChannel( obj ) {
  var name, status, logo, url, game;
  
  name = obj.display_name;
  status = obj.status;
  logo = obj.logo;
  url = obj.url;
  game = obj.game;
  
  var channel,onoff;

  if ( status && status.length > 16) {
  	status = status.substr(0, 16) + "....";
  }


  if ( game === null ) {
  	onoff = "offline";
  }
  else {
  	onoff = "online";
  }
  
  channel = "<a>";
  channel +=  "<h3>" + name + "</h3>";
  channel += "<img src='" + logo + "'>";
  channel += "<p>" + status + "</p>";
  $(channel).attr('class', onoff);

  $("#container").append(channel);
  
  
}


function searchUsers( arr ) {
	var searchBox = $("input[type='text']");

	$(searchBox).keyup( function(){

		var chars = $(searchBox).val();

		$("arr").each(function (item){
			if($(item).find('h3').text().indexOf(chars) < 0) {
				$(this).parent().closest('a').hide();
			}
			else {
				$(this).parent().closest('a').show();
			}
		});
	});
}

我尝试更新您的代码，希望这有帮助

    var base = "https://api.twitch.tv/kraken/users/";
var key = "myKey&callback";
var users = ["ESL_SC2", "OgamingSC2", "cretetion", "freecodecamp",
             "storbeck", "habathcx", "RobotCaleb", "noobs2ninjas",
             "TwinGalaxiesLive","MedryBW", "frontender007","Gronkh"];



$(document).ready(function(){
  requestData(users);
  searchUsers(users);

});

function requestData ( arr ) {
  arr.forEach ( function ( user ) {
    var url = base + user + '/?client_id=' + key + '&callback=?';
    $.getJSON(url, function ( json ) {

      displayChannel(json);

    });
  });
}

function displayChannel( obj ) {
  var name, status, logo, url, game;

  name = obj.display_name;
  status = obj.status;
  logo = obj.logo;
  url = obj.url;
  game = obj.game;

  var channel,onoff;

  if ( status && status.length > 16) {
    status = status.substr(0, 16) + "....";
  }


  if ( game === null ) {
    onoff = "offline";
  }
  else {
    onoff = "online";
  }

  channel = "<a id="+name+">";
  channel +=  "<h3>" + name + "</h3>";
  channel += "<img src='" + logo + "'>";
  channel += "<p>" + status + "</p>";
  $(channel).attr('class', onoff);

  $("#container").append(channel);


}


function searchUsers( arr ) {
    var searchBox = $("input[type='text']");

        var chars = $(searchBox).val();

        $.each( arr, function( i, val ) {

            if(val==chars) {
                $('a#'+chars).siblings().hide();
            }
            else {
                $(this).parent().closest('a').show();
            }
        });

}
$("input[type='text']").change(function(){

    searchUsers(users);
});

使用jQuery搜索项目的简单搜索功能不起作用
