从查询中清除以前的结果

Question

通过附加的代码，我根据用户名在 youtube 上进行了搜索，并显示了结果。如果我搜索两次，结果就会相加。我想删除以前的结果。我尝试使用 htmlString = card; 但它只显示一个结果。感谢所有想帮助我解决这个问题的人。var musicCards = [];jQuery(document).ready(function() {      jQuery("#searchButton").on("click", function() {                 var query = jQuery("#queryInput").val();             if (query != "") {           loadYoutubeService(query);                       console.log(query + "");        }    });});function loadYoutubeService(query) {    gapi.client.load('youtube', 'v3', function() {        gapi.client.setApiKey('ADADADADADA');        search(query);    });}function search(query) {       var request = gapi.client.youtube.search.list({        part: 'snippet',        q: query,         type: 'channel',        maxResults: 15    });    request.execute(function(response) {               jQuery.each(response.items, function(i, item) {               if (!item['']) {                var musicCard = {};                musicCard._id = item['snippet']['customUrl'];                musicCard.title = item['snippet']['title'];              musicCard.linkprofilo = item['snippet']['channelId'];                musicCard.url = "https://www.youtube.com/channel/";                musicCard.description = item['snippet']['description'];                musicCard.immagine = item['snippet']['thumbnails']['high']['url'];                musicCards.push(musicCard);            }                                 });         renderView();    });}function renderView() {    var htmlString = "";    musicCards.forEach(function(musicCard, i) {        var card = createCard(musicCard._id, musicCard.title, musicCard.description, musicCard.url,musicCard.immagine, musicCard.linkprofilo);        htmlString += card;    });      jQuery('#youtube-utente').html(htmlString);}}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>

Answer 1

解决使用：

  request.execute(function(response) {

   musicCards.length = 0; // clear array
