Question

我是编程新手，需要一些帮助。

我有以下javascript，其中我从excel中提取数据，但是我无法以表格格式显示变量输出。有人可以指导我如何在表格中显示变量（“exData1”）和（“exData2”）。

<script class="ms-rteThemeForeColor-2-0" type="text/javascript"> ExecuteOrDelayUntilScriptLoaded(init,'sp.js'); var currentUser; var idData; var titleData; function init(){
    this.clientContext = new SP.ClientContext.get_current();
    this.oWeb = clientContext.get_web();
    currentUser = this.oWeb.get_currentUser();
    this.clientContext.load(currentUser);
    this.clientContext.executeQueryAsync(Function.createDelegate(this,this.onQuerySucceeded), Function.createDelegate(this,this.onQueryFailed)); }

function onQuerySucceeded() {
    document.getElementById('userLoginName').innerHTML = currentUser.get_loginName(); 
    document.getElementById('userTitle').innerHTML = currentUser.get_title(); 
    idirData = currentUser.get_loginName();
    titleData = currentUser.get_title(); }

function onQueryFailed(sender, args) {
    alert('Request failed. \nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace()); }

function GetExcelData1(){
    var excel = new ActiveXObject("Excel.Application");
    var excelFile = excel.Workbooks.Open("Usage.xlsx");
    var excelSheet = excelFile.Worksheets.Item(2);
    var column = 1;
    for (;;){
        var excelData = excelSheet.Cells(column,1).Value;
        if (idData.toLowerCase() == "id\\"+excelData.toLowerCase() || excelData == "") break;
        column++;
    }
    var excelData = excelSheet.Cells(column,3).Value;
    document.getElementById("exData1").innerHTML = excelData+"GB";
    excel.DisplayAlerts = false;
    excel.Quit();
    excel = null;
    idTmr = window.setInterval("Cleanup();",1); }



</script>

          cell3.innerHTML = "<p>"+excelData1+" "+excelData2+"</p>";
       }

     {
       alert("Error load Excel files"+ ex.message);
     }
