if else Ajax success restapi Sharepoint Online

Question

我试图显示一个自定义'无新上传'消息时，其余api返回成功事件上没有条目。当Success事件返回行并在0项时显示空白时，下面的代码可以完美地工作。

我试着实现if else语句，没有运气。请协助。

$(function(){
var today = new Date();
today = moment(today).format("YYYY-MM-DD");
var currentDate = today+'T00:00:00.000Z';
var requestUri = "@SPO_SITE@/_api/web/lists/getbytitle('LIST_NAME')/items?$top=20000&$select=DistrDate,EncodedAbsUrl&$filter= DistrDate ge datetime'" +currentDate+ "'";
$.ajax({
url: requestUri,
type: "GET",
headers: {
"accept":"application/json; odata=verbose"
},
success: onSuccess,
});
function onSuccess(data) {
var objItems = data.d.results;
var tableContent = '<table id="mbrTable" style="width:100%"><caption class="text-info">Report</caption>';
for (var i = 0; i < objItems.length; i++) {
tableContent += '<tr>';
tableContent += '<td>' + moment(objItems[i].DistrDate).format("DD-MM-YYYY") + " - " + "<a target='_blank' href=" + objItems[i].EncodedAbsUrl + ">" + "View" + "</a>" + '</td>';
tableContent += '</tr>';
}
document.getElementById("mbrTable").innerHTML = (tableContent);
}
});

下面修复了这个问题。

$(function(){
var today = new Date();
today = moment(today).format("YYYY-MM-DD");
var currentDate = today+'T00:00:00.000Z';
var requestUri = "@SPO_SITE@/_api/web/lists/getbytitle('LIST_NAME')/items?$top=20000&$select=DistrDate,EncodedAbsUrl&$filter= DistrDate ge datetime'" +currentDate+ "'";
$.ajax({
url: requestUri,
type: "GET",
headers: {
"accept":"application/json; odata=verbose"
},
success: onSuccess,
});
function onSuccess(data) {
var objItems = data.d.results;
if (objItems.length == 0) {
var tableContent = '<table id="mbrTable" style="width:100%"><caption class="text-info">Report</caption><tr><td>No new uploads</td></tr>';
}
else {
var tableContent = '<table id="mbrTable" style="width:100%"><caption class="text-info">Report</caption>';
for (var i = 0; i < objItems.length; i++) {
tableContent += '<tr>';
tableContent += '<td>' + moment(objItems[i].DistrDate).format("DD-MM-YYYY") + " - " + "<a target='_blank' href=" + objItems[i].EncodedAbsUrl + ">" + "View" + "</a>" + '</td>';
tableContent += '</tr>';
}
}
document.getElementById("mbrTable").innerHTML = (tableContent);
}
});
