  • Artikel

This post is a contribution from Jaishree Thiyagarajan, an engineer with the SharePoint Developer Support team.

Here’s the sample.

Create a simple HTML page and add the below scripts.

 <html>
  
 <head>
     <title></title>
     <script 
         src="https://ajax.aspnetcdn.com/ajax/4.0/1/MicrosoftAjax.js" 
         type="text/javascript">
     </script>
     <script
         type="text/javascript"
         src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.2.min.js">
     </script> 
 </head>
 <body>
     <script type="text/javascript">
  
         $(document).ready(function () {
  
  
             var hostweburl = "https://siteURL/";
  
              
             var scriptbase = hostweburl + "/_layouts/15/";
  
  
             $.getScript(scriptbase + "SP.Runtime.js",
                 function () {
                     $.getScript(scriptbase + "SP.js", execOperation);
                 }
             );
         });
  
  
         function execOperation() {
  
              
             AddWebSiteProperties("https://siteURL");
  
         }
         function AddWebSiteProperties(siteUrl) {
  
             var clientContext = new SP.ClientContext(siteUrl);
  
             oWebsite = clientContext.get_web();
             alert(oWebsite);
             
             clientContext.load(oWebsite);
             alert("Load");
             var props = oWebsite.get_allProperties();
  
             props.set_item("Myproperty", "PropertyValue");
             oWebsite.update();
             clientContext.load(oWebsite);
  
             clientContext.executeQueryAsync(
                 Function.createDelegate(this, this.onQuerySucceeded2),
                 Function.createDelegate(this, this.onQueryFailed2)
              );
         }
  
  
  
  
  
  
         function onQuerySucceeded2(sender, args) {
             alert("Success");         }
  
         function onQueryFailed2(sender, args) {
             alert("Failed");
             alert('Request failed. ' + args.get_message() +
                 '\n' + args.get_stackTrace());
         }
  
 </script>
     Hi there

 </html>

You can check whether the property value is added or not by various methods.  One of the way is to directly browse to the site like: https://intranet.contoso.com/\_api/web/AllProperties?$select=Myproperty.

Hope this was helpful!
