[英]How to Make Script Flexible when New Item is Loaded in SharePoint Folder
我正在尋求有關 JavaScript 腳本的幫助，以便在將新項目（視頻）添加到我的 SharePoint 文件夾時使其可擴展。 我創建了一個計數器，每次選擇視頻按鈕時都會進行計數，並在 div 中顯示新計數。 該腳本按預期工作，但我喜歡擴展它的功能，以便在將新視頻添加到 SharePoint 視頻文件夾時自動調整。 視頻在放入文件夾時會動態添加到 HTML 頁面。 但是，當我添加一個新視頻時，它會加載到零索引 position 並將其他視頻下移一個； 制作上一個視頻中的零索引 position 到一個 position 等等。 有人可以查看我的腳本並查看嗎？ 如果可能的話，當加載新視頻時，如何使我當前的腳本相應地調整？ 我喜歡在不需要將 go 重新放入腳本並在添加新視頻時手動重新編號所有內容的地方。 我希望這個問題有意義。

我如何向 HTML 添加內容：我使用 REST API 獲取選項來檢測加載到 Z97F2940F6993DFEB04673 文件夾中的新項目。
getFilesFromFolder("/sites/dcsa/ep/epMainFilesBI/video").done(function(data){
然后我使用以下腳本將文件夾中的項目連接到 HTML 頁面：
$("#column1 ol").append('<li style="width:30%; height: auto; position: relative; left: 5%; padding-right: 10px; padding-bottom: 10px; text-align: center; font-size: 12px; float: left;" data-event-date="' + item.TimeCreated.split("T")[0] + '"><div class="btnImg" id="growPlayPauseBtn'+ i +'" style="width: 285px; height: 225px; position: absolute; top: 20px; z-index: 10; cursor: pointer; padding: 10px; color: white; background-color: rgba(43, 92, 171, .35); display: block;">Play Video</div><video width="100%" height="auto" controls onended="videoEnded1()" id="videoClip'+ i +'"><source src="' + item.ServerRelativeUrl + '" type="audio/mpeg" >' + item.Name.replace(/\.[^/.]+$/, "") + " - " + '<span style="color: red;">' + item.TimeCreated.split('T')[0] + '</span>' + '</video><span style="text-align: center; font-size: 12px; float: left; clear: both;" "' + item.TimeCreated.split("T")[0] + '">' + item.Name.replace(/\.[^/.]+$/, "") + " - " + item.TimeCreated.split('T')[0] + '</span></br><div class="vidViews" id="vidHit'+ i +'">Views: <span></span></div></li>');
如果我很好地理解了你的代碼，新項目是在else part創建的，所以我建議你做一個第一個循環來檢測新視頻中的舊視頻並在之后創建 html：
getFilesFromFolder("/sites/dcsa/ep/epMainFiles/BI/video").done(function(data) {
$.each(data.d.results, function(index, item) {
var spDate = new Date(item.TimeCreated.split('T')[0]) //example: '2015-10-30T05:00:00Z'
var newTillDate = new Date();
spDate.setDate(spDate.getDate() + 2);
var newitems = [], olditems= [];
if (spDate <= newTillDate) {
olditems.push(item);
} else {
newitems.push(item);
}
var nbrolditems = olditems.length;
for(let i = 0;i < nbrolditems; i++){
let item = olditem[i];
jQuery("#hiddenWrapper").fadeIn();
$("#column1 ol").append('<li style="width:30%; height: auto; position: relative; left: 5%; padding-right: 10px; padding-bottom: 10px; text-align: center; font-size: 12px; float: left;" data-event-date="' + item.TimeCreated.split("T")[0] + '"><div class="btnImg" id="growPlayPauseBtn' + i + '" style="width: 285px; height: 225px; position: absolute; top: 20px; z-index: 10; cursor: pointer; padding: 10px; color: white; background-color: rgba(43, 92, 171, .35); display: block;">Play Video</div><video width="100%" height="auto" controls onended="videoEnded1()" id="videoClip' + i + '"><source src="' + item.ServerRelativeUrl + '" type="audio/mpeg" >' + item.Name.replace(/\.[^/.]+$/, "") + " - " + '<span style="color: red;">' + item.TimeCreated.split('T')[0] + '</span>' + '</video><span style="text-align: center; font-size: 12px; float: left; clear: both;" "' + item.TimeCreated.split("T")[0] + '">' + item.Name.replace(/\.[^/.]+$/, "") + " - " + item.TimeCreated.split('T')[0] + '</span></br><div class="vidViews" id="vidHit' + i + '">Views: <span></span></div></li>');
$("#column1 h3").html("Videos");
}
for(let j = 0;j < newitems.length; j++){
let item = olditem[j;
let i = j + nbrolditems;
jQuery("#hiddenWrapper").fadeIn();
$("#column1 ol").append('<li style="width:30%; height: auto; position: relative; left: 5%; padding-right: 10px; padding-bottom: 10px; text-align: center; font-size: 12px; float: left;" data-event-date="' + item.TimeCreated.split("T")[0] + '"><div class="btnImg" id="growPlayPauseBtn' + i + '" style="width: 285px; height: 225px; position: absolute; top: 20px; z-index: 10; cursor: pointer; padding: 10px; color: white; background-color: rgba(43, 92, 171, .35); display: block;">Play Video</div><video width="100%" height="auto" controls onended="videoEnded1()" id="videoClip' + i + '"><source src="' + item.ServerRelativeUrl + '" type="audio/mpeg" >' + item.Name.replace(/\.[^/.]+$/, "") + " - " + '<span style="color: red;">' + item.TimeCreated.split('T')[0] + '</span>' + '</video><span style="text-align: center; font-size: 12px; float: left; clear: both;" "' + item.TimeCreated.split("T")[0] + '">' + item.Name.replace(/\.[^/.]+$/, "") + " - " + item.TimeCreated.split('T')[0] + '</span></br><div class="vidViews" id="vidHit' + i + '">Views: <span></span></div></li>');
$("#column1 h3").html('<img class="newArrow" style="width: 60px; position: relative; right: 5px; top: 0px;"src="../SiteAssets/SitePages/Test Page/icons/arrow-with_new2.gif" alt="logo">Videos');
}
});
});
另一個想法是按視頻創建日期對列表進行排序......
