Question

我正在使用Javascript中的以下函数从SharePoint上两个单独的列表中提取数据，并将结果数据传递给另一个函数。我花了过去几个小时尝试调试此功能，并出现以下错误：

jQuery.Deferred异常：不允许重复的参数名称此上下文SyntaxError：在此不允许重复的参数名称语境在Array。

被告知错误发生在此行：

  successFunction(RecordResponse, RecordAmountResponse)

奇怪的是，它确实通过了两个.done函数并输出了它们各自的检查标志，但是我知道我无法更改.then（function（）{}）中的参数，否则我的successFunction将不会收到响应所需的数据。

这是我正在调用的函数：

function getReportData(strRecordQuery, strRecordAmountQuery, successFunction, failFunction) {

    // Use promise methods to run getListQuery from both tblRecord and tblRecordData

    var RecordDataInfo = $.Deferred();
    var RecordAmountDataInfo = $.Deferred();

    var dfdRecordDataFiles;
    var dfdRecordAmountDataFiles;

    dfdRecordDataFiles = getListQuery('lstRecord', strRecordQuery, true);

    dfdRecordAmountDataFiles = getListQuery('lstRecordAmount', strRecordAmountQuery, true);

    dfdRecordDataFiles.done(function(RecordDataResponse) {
        console.log("dfdRecordDataFiles.done");
        RecordDataInfo.resolve(RecordDataResponse);
    });

    dfdRecordAmountDataFiles.done(function(RecordAmountDataResponse) {
        console.log("dfdRecordAmountDataFiles.done");
        RecordAmountDataInfo.resolve(RecordAmountDataResponse);
    });

    dfdRecordDataFiles.fail(function(error) {
        console.log("dfdRecordDataFiles.fail");
        console.log("ResponseText: " + error.responseText);
        console.log(JSON.stringify(error));
        RecordDataInfo.fail(error);
    });

    dfdRecordAmountDataFiles.fail(function(lerror) {
        console.log("dfdRecordAmountDataFiles.fail");
        console.log("ResponseText: " + lerror.responseText);
        console.log(JSON.stringify(lerror));
        RecordAmountDataInfo.fail(lerror);
    });

    $.when(RecordDataInfo, RecordAmountDataInfo)
        .then(function(RecordResponse, RecordAmountResponse) {
          successFunction(RecordResponse, RecordAmountResponse)
        }, function(error, lerror) {
          failFunction(error, lerror);
        });
};

由于我已经厌倦了盯着它看而又不明白这一点，我能否再给我第二眼的帮助呢？

修改

我已根据建议修改了代码，但收到类似错误：

function getListQuery(listName, queryString) {

    // REST Call
    return $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('" + listName + "')/items?" + queryString,
        type: "GET",
        headers: { ACCEPT: "application/json;odata=verbose" }
    });
};

function getReportData(strRecordQuery, strRecordAmountQuery, strRecordPersonnelQuery) {

    return $.when(getListQuery('lstRecord', strRecordQuery, true), getListQuery('lstRecordAmount', strRecordAmountQuery, true), getListQuery('lstRecordPersonnel', strRecordPersonnelQuery, true))
};

function setReportQueries(Yr0, Yr1, Yr2, Yr3, Yr4) {

    // Specific to the report
    strRecordQuery = "$select=ID,RecordName";
    strRecordAmountQuery = "$select=ID,Parameter1,Year,Amount&$filter=(Year eq '" + Yr0 + "') or (Year eq '" + Yr1 + 
                        "') or (Year eq '" + Yr2 + "') or (Year eq '" + Yr3 + "') or (Year eq '" + Yr4 + "')"; 
    strRecordPersonnelQuery = "$select=ID, Parameter1&$filter=(Year eq '" + Yr0 + "') or (Year eq '" + Yr1 + 
                        "') or (Year eq '" + Yr2 + "') or (Year eq '" + Yr3 + "') or (Year eq '" + Yr4 + "')";

    getReportData(strRecordQuery, strRecordAmountQuery, strRecordPersonnelQuery).then(loadReportTables);

};

function loadReportTables(RecordData, RecordAmountData, RecordPersonnelData) {

console.log("Enter loadReportTables()");

/* Do Stuff */

}

我得到的错误是：

jQuery.Deferred异常：不允许重复的参数名称此上下文SyntaxError：在此不允许重复的参数名称语境在l（https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.3.1.min.js:2:29375）在c（https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.3.1.min.js:2:29677）未定义

jQuery延迟例外：不允许重复参数
