我正在尝试创建一个从YouTube返回的搜索结果的可排序表格。我能够很好地创建搜索引擎，我可以创建一个可排序的表。但现在我试图连接两者。
我知道主要问题是当页面加载时没有结果要排序;在执行搜索之前没有表格。
我查看了这个讨论，我认为有一些东西供我使用，但我不知道如何整合它。
这是我到目前为止所做的工作：
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() {
$("form").on("submit", function(e){
e.preventDefault();
// prepare the request
var request = gapi.client.youtube.search.list({
part: "snippet",
type: "video",
q: encodeURIComponent($("#search").val()).replace(/%20/g, "+"),
maxResults: 5,
publishedAfter: "2015-01-01T00:00:00Z",
relevanceLanguage: "en"
});
// execute request
request.execute(function(response) {
// console.log(response); // test by logging to console
var results = response.result;
$("#results").html(""); // reset results
// loop through each returned item
$.each(results.items, function(index, item) {
console.log(item); // test by logging to console
$.get("tpl/results-sortable-table.html", function(data) {
$("#results").append(tplawesome(data,
[{
"title": item.snippet.title,
"description": item.snippet.description,
"channelTitle": item.snippet.channelTitle,
"publishedAt": item.snippet.publishedAt,
}]
));
});
});
resetVideoHeight();
});
});
$(window).on("resize", resetVideoHeight); // reset video height when window is resized
});
function resetVideoHeight() {
$(".video").css("height", $("#results").width() * 9/16);
}
function init() {
gapi.client.setApiKey(""); // Removed on purpose
gapi.client.load("youtube", "v3", function() {
// yt api is ready
});
}
// THE SORTING SCRIPT
// I think I need to include something here that listens for when the table is populated. Is that right?
// --------------------------------------------------------------------
// COMPARE OBJECT
// --------------------------------------------------------------------
// Create a general "compare" object that will compare values in a table
var compare = {
name: function(a, b) { // For genre and title (data-type = name) ...
a = a.replace(/^the /i, ''); // Remove "the" from start (^) of parameter a ...
b = b.replace(/^the /i, ''); // and parameter "b".
a = a.replace(/^a /i, ''); // Remove "a" from start (^) of parameter a ...
b = b.replace(/^a /i, ''); // and parameter "b".
a = a.replace(/^an /i, ''); // Remove "a" from start (^) of parameter a ...
b = b.replace(/^an /i, ''); // and parameter "b".
a = a.toUpperCase(); // Convert a to uppercase
b = b.toUpperCase(); // Convert b to uppercase
if (a < b) { // If a is less than b ...
return -1; // ???????? return -1 indicating a should be before b, ...
} else { // otherwise ...
return a > b ? 1 : 0; // return 1 if a is greater than b or ...
} // return zero (if the are the same).
},
// --------------------------------------------------------------------
// DATE METHOD
// --------------------------------------------------------------------
// Create a "date" method that will compare and sort two dares by using the date function to ...
// convert string to date, and sort them based on their values.
date: function(a, b) { // Add a method called date
a = new Date(a); // New Date object to hold the date
b = new Date(b); // New Date object to hold the date
// Compare dates and return result
return a > b ? 1 : 0; // return 1 if a is greater than b or ...
// return zero (if the are the same).
},
};
// --------------------------------------------------------------------
// SORT TABLE SCRIPT
// --------------------------------------------------------------------
$('.sortable').each(function() {
// Establish variables
var $table = $(this); // The current sortable table.
var $tbody = $table.find('tbody'); // Store this table's tbody in $tbody.
var $thcontrols = $table.find('th'); // Store this table's th in $thcontrols.
var rows = $tbody.find('tr').toArray(); // Store an array of tr's in rows.
$thcontrols.on('click', function() { // When user clicks on a th
var $th = $(this); // Get the th that was clicked on
var datasort = $th.data('sort'); // Get value of this th's data-sort attribute and store it in datasort.
var column; // Declare the column variable.
// If selected item already has ascending or descending class, then it's already sorted so reverse contents.
if ($th.is('.ascending') || $th.is('.descending')) { // If th is .ascending or .descending ...
$th.toggleClass('ascending descending'); // switch their classes and ...
$tbody.append(rows.reverse()); // Reverse the headers array of rows.
} else { // Otherwise perform a sort
// If compare object has method that matches the value of the data-type attribute for this column ...
if (compare.hasOwnProperty(datasort)) { // Note: datasort is $th.data('sort')
column = $thcontrols.index(this); // ... get the th's index number.
rows.sort(function(a, b) { // Sort values in rows array.
a = $(a).find('td').eq(column).text(); // Find text of the td in the column in row a, ...
b = $(b).find('td').eq(column).text(); // find text of the td in the column in row b and ...
return compare[datasort](a, b); // compare them.
});
$th.addClass('ascending'); // Add .ascending to th and ...
$th.siblings().removeClass('ascending descending'); // remove asc or desc from all other headers. And ...
$tbody.append(rows); // Append the rows to the table body
}
}
});
});

<p><input type="submit" value="Search" class="form-control btn btn-primary w100"></p>
</form>
<table class="sortable">
<thead>
<tr>
<th data-sort="name">Title</th>
<th data-sort="name">Description</th>
<th data-sort="name">Channel Title</th>
<th data-sort="date">Published At</th>
</tr>
</thead>
<tbody id="results">
<!-- results go here -->
</tbody>
</table>
</div>

<!-- scripts -->

<script src="js/app.js"></script>
<script src="https://apis.google.com/js/client.js?onload=init"></script>
</body>
</html>
结果可排序-table.html
<tr onload="sort()" class="item">
<td>{{title}}</td>
<td>{{description}}</td>
<td>{{channelTitle}}</td>
<td>{{publishedAt}}</td>
</tr>
我知道我把所有东西和厨房都放在这里，但我知道这一切所以我不确定什么是重要的。
感谢任何可以提供帮助的人，

我知道主要问题是当页面加载时没有结果要排序;在执行搜索之前没有表格。
有些事情可能会让您朝着正确的方向前进并解决上述问题：
$('.sortable').each(function() { resetVideoHeight();
