How would I check in javascript if web part zones have no web parts?


1 Answer 1


You can check if a page has some webparts or not.

var siteUrl = '/sites/MySiteCollection';
var serverRelativeUrl = '/sites/MySiteCollection/Default.aspx';

function updateWebPartTitle() {    
    this.clientContext = new SP.ClientContext(siteUrl);
    var oFile = clientContext.get_web().getFileByServerRelativeUrl(serverRelativeUrl);    
    var limitedWebPartManager = oFile.getLimitedWebPartManager(SP.WebParts.PersonalizationScope.shared);
    this.collWebPart = limitedWebPartManager.get_webParts();    
    clientContext.executeQueryAsync(Function.createDelegate(this, this.SuccessFunc), Function.createDelegate(this, this.onQueryFailed));

function SuccessFunc() {    
    if (!collWebPart.get_count()) {
        alert('No Web Parts on this page.');

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

Check MSDN source here.


If you know the webpartzone id and try something like this.

<div class="inner"> 
<WebPartPages:WebPartZone id="zone1"><ZoneTemplate></ZoneTemplate></WebpartPages:WebPartZone> 

then query the zone and see it has table element because generally webpart will be rendered in a table.

if($('#zone1').find('table').length != 0){
        //webpart exists

You may need to adjust your code based on actual dom.I can not test it now.

  • Its not about checking if a page has web parts, its about if a specific zone has any web parts using only DOM checking with javascript, and no ajax calls.

  • @omega then probably you have to inspect the zone area by F12 and check for descendant element length is 0 or not using js.And to me this will be a bad idea.

  • I need it to be in js, and was wondering if anyone has this code already.
