I am having a looping issue with my YouTube API script. The code below shows my code. The issue that I am having is that after I get a response back from the server through jquery ajax, I alert the YouTube ID of a selected specific video. For some reason, it alerts it three times. I tried modifying the code adding the ajax call outside of the loop, but it doesn't seem to work. Any help would be greatly appreciated.
Below is the app.js
function tplawesome(e,t){res=e;for(var n=0;n<t.length;n++){res=res.replace(/\{\{(.*?)\}\}/g,function(e,r){return t[n][r]})}return res}
$(function() {
$("form").on("submit", function(e) {
e.preventDefault();
// prepare the request
var request = gapi.client.youtube.search.list({
part: "snippet",
type: "video",
headers: {referer: "//localhost/"},
q: encodeURIComponent($("#search").val()).replace(/%20/g, "+"),
maxResults: 3 // Set this to the number you want to display on the page.
});
// execute the request
request.execute(function(response) {
var results = response.result;
$("#results").html("");
$.each(results.items, function(index, item) {
$.get("tpl/item.html", function(data) {
$("#results").append(tplawesome(data, [{"title":item.snippet.title, "videoid":item.id.videoId}]));
$('.selection').on('click', function () {
let url = "update_db.php";
let song_name2 = item.snippet.title;
let youtube_id = item.id.videoId;
$.ajax({
dataType: "JSON",
url: url,
type: "GET",
data: {song_name2: song_name2, youtube_id: youtube_id},
success: function (data) {
alert("YouTube ID: " + youtube_id );
//ALERTS 3 TIMES. HOW TO FIX IT???
/*if(data.msg === "success"){
console.log(data.result);
alert(data.result);
} else {
console.log(data.result);
alert(data.result);
}*/
}
});
});
});
}); // for each loop
resetVideoHeight();
});
});
$(window).on("resize", resetVideoHeight);
});
function resetVideoHeight() {
$(".video").css("height", $("#results").width() * 9/16);
}
function youtube_api() {
gapi.client.setApiKey("PUBLIC KEY");
gapi.client.load("youtube", "v3", function() {
// yt api is ready
});
}
Below is the item.html
<div class="item">
<h2>Title: <strong><span style="color: red">{{title}}</span></strong></h2>
<h2><span class="selection">I will like to perform this selection</span></h2>
<iframe class="video w100" width="640" height="360" src="https://www.youtube.com/embed/{{videoid}}" frameborder="0" allowfullscreen></iframe>
