createElement <a href=variable1> variable2 </a>

Question

我需要在SharePoint 2010中创建导航Web部件.我使用表来显示SharePoint列表中的项目,并且表格的结构如下:

Column1 =要显示的文本(标题)Column2 = URL(TitleLink)

我似乎无法弄清楚如何创建<a href></a>标记并将变量放在appropraite的位置.我不断得到的结果只是<th>标签中的HTML标记.我在谷歌的很多地方搜索过,但还没有找到一个好的答案.

下面是关于使用变量打印表头的工作正常的代码.但是,在该打印文本(theHeaderText)后面我想在其后面添加一个链接,以便当用户点击时,它会转到该链接.

var siteUrl = '/sites/dev/';
var theCounter = 0;
ExecuteOrDelayUntilScriptLoaded(retrieveListItems, "sp.js");

function retrieveListItems() {
var clientContext = new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('myList');
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml("<Where><And><IsNotNull><FieldRef Name='Title' /></IsNotNull>    <IsNotNull><FieldRef Name='TitleLink' /></IsNotNull></And></Where>");
this.collListItem = oList.getItems(camlQuery);
clientContext.load(collListItem);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded),     Function.createDelegate(this, this.onQueryFailed));
}

function onQuerySucceeded(sender, args) 
{
var listItemEnumerator = collListItem.getEnumerator();
    while (listItemEnumerator.moveNext()) 
    {
    var oListItem = listItemEnumerator.get_current();

    //Each column in in the SharePoint List will essentially become an array.
    //So make an array for each column that will be returned!

    var theHeaders = new Array();
    var HeaderLinks = new Array();
    theCounter += 1;
    theHeaders[theCounter - 1] = oListItem.get_item('Title');
    HeaderLinks[theCounter - 1] = oListItem.get_item('TitleLink');

    //Get the Table Element created in HTML
    var getTheTableTag = document.getElementById('theTable');


    //Create the headers (top level links)
    var createTheHeaderElements = document.createElement('th');
    createTheHeaderElements.id = 'headerTag';
    var theHeaderText = document.createTextNode(theHeaders[theCounter - 1]);
    createTheHeaderElements.appendChild(theHeaderText);
    getTheTableTag.appendChild(createTheHeaderElements);

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

使用setAttribute这样:

        var createA = document.createElement('a');
        var createAText = document.createTextNode(theCounter);
        createA.setAttribute('href', "http://google.com");
        createA.appendChild(createAText);
        getTheTableTag.appendChild(createA);

更具互动性的例子:

const insertButton = document.getElementById('insertButton');

const appendAnchorTag = () => {
  const anchor = document.createElement('a');
  const list = document.getElementById('linksList');
  const li = document.createElement('li');
  anchor.href = 'http://google.com';
  anchor.innerText = 'Go to Google';
  li.appendChild(anchor);
  list.appendChild(li);
};

insertButton.onclick = appendAnchorTag;

<button id="insertButton">Create New Anchor Tag</button>

<ul id="linksList"></ul>
