我想製作一個簡單的應用程序，調用api並獲取用戶數據。當用戶數據顯示在頁面上時，我想用他們的用戶名搜索用戶。嘗試了很多次，但沒有成功。任何人都可以幫忙嗎？簡單的搜索功能與jQuery搜索項不起作用
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) {
\t status = status.substr(0, 16) + "....";
}
if (game === null) {
\t onoff = "offline";
}
else {
\t 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) {
\t var searchBox = $("input[type='text']");
\t $(searchBox).keyup(function(){
\t \t var chars = $(searchBox).val();
\t \t $("arr").each(function (item){
\t \t \t if($(item).find('h3').text().indexOf(chars) < 0) {
\t \t \t \t $(this).parent().closest('a').hide();
\t \t \t }
\t \t \t else {
\t \t \t \t $(this).parent().closest('a').show();
\t \t \t }
\t \t });
\t });
