Hey everyone,
I’m working on a SharePoint project and I’ve got a question about web parts. I’ve created a custom web part with a personalizable property. Now I’m trying to figure out if there’s a way to change the value of this property using JavaScript.
Has anyone done this before? I’m not sure if it’s even possible, but I thought I’d ask here before giving up. If it is doable, could you point me in the right direction or share some tips on how to approach this?
Thanks in advance for any help or advice you can offer!
I’ve dealt with this issue before in SharePoint development. Updating custom web part properties via JavaScript is indeed possible, but it requires a specific approach. The most reliable method I’ve found is using the SharePoint REST API. You’ll need to authenticate properly and use SP.RequestExecutor for making API calls. The process involves first retrieving the current web part properties, then sending a POST request to update the specific property you’re targeting. Be careful with the request headers, especially the RequestDigest - getting this wrong can lead to frustrating 403 errors. If you’re working within the SharePoint Framework (SPFx), the process is somewhat simpler as you can directly manipulate properties using this.properties in your web part’s code. Let me know if you need more specific guidance on implementation.
I’ve tackled this problem before in one of my SharePoint projects. It’s definitely possible to update a custom web part property using JavaScript, but it requires a bit of finesse.
The approach I found most effective was using the SharePoint REST API. You’ll need to make sure you have the right permissions first. Then, you can use the SP.RequestExecutor to handle authentication and make the API calls.
The basic flow is to first get the current web part properties, then send a POST request to update the specific property you want to change. It’s a bit tricky to get the syntax right, especially with the headers and body of the request.
One gotcha to watch out for: make sure you’re including the correct RequestDigest value in your headers, or you’ll keep getting 403 errors.
If you’re using the SharePoint Framework (SPFx), it’s actually a bit easier. You can update properties directly within your web part’s code using this.properties.
Hope this helps point you in the right direction. Let me know if you need any more specific guidance!
Hey Tom42Gamer, i’ve done this before! It’s totally possible with the SharePoint REST API. You’ll need to use SP.RequestExecutor for authentication and make API calls. Get the current properties first, then send a POST request to update the specific one. Watch out for the RequestDigest in headers tho. let me know if u need more help!
