Question

我正在尝试使用JavaScript检索列表数据。但出了点问题。我正在尝试调试代码，但我无法理解这一点以下是JavaScript代码：

ExecuteOrDelayUntilScriptLoaded(PopulateDepartments, "sp.js");
var _ctx = null;
var _web = null;
var _allItems = null;

function PopulateDepartments() {
    debugger;
    _ctx = SP.ClientContext.get_current();
    _web = _ctx.get_web();
    var list = _web.get_lists().getByTitle("ServiceType");
    var query = new SP.CamlQuery();
    query.set_viewXml("<View><Query><OrderBy><FieldRef Name='Title'/></OrderBy></Query></View>");
    _allItems = list.getItems(query);
    _ctx.load(_allItems, 'Include(Title,ID)');
    debugger;
    _ctx.executeQueryAsync(Function.createDelegate(this, this.PopulateDepartmentSuccess),
        Function.createDelegate(this, this.PopulateDepartmentFaild));
}

function PopulateDepartmentSuccess() {
    var ddlEntry = this.document.getElementById("ddl1");
    ddlEntry.options.length = 0;
    var listEnumerator = _allItems.getEnumerator();
    while (listEnumerator.moveNext()) {
        var currentItem = listEnumerator.get_current();
        ddlEntry.options[ddlEntry.options.length] = new Option(currentItem.get_item("Title"), currentItem.get_item("ID"));
    }
}

function PopulateDepartmentFaild() {
    alert("Something went Wrong....!!");
}

每当我运行此代码时，它会显示警报框请帮助..

Answer 1

有时候这没有采用正确的引用。检查它是否可以删除此引用.so而不是这个 _ctx.executeQueryAsync（Function.createDelegate（this，this.PopulateDepartmentSuccess）， Function.createDelegate（this，this.PopulateDepartmentFaild））;

尝试使用类似的东西

_ctx.executeQueryAsync（PopulateDepartmentSuccess，PopulateDepartmentFaild）;

我认为。如果您正在创建Sharepoint应用程序，则需要在AppManifest.xml中为Web授予权限。

如何使用JQuery或JavaScript和Fill DropDownList检索sharepoint 2013列表数据？
