sharepoint 2019 webpart js

Hi eboulard,

Certainly! You can modify a list web part on a page in SharePoint 2019 using JavaScript. JavaScript allows you to customize the behavior and properties of the web part, such as changing the view based on a parameter from the URL. Here's a simple approach you can follow:

1. Identify the list web part: Use JavaScript to find the specific list web part on the page. You can do this by targeting its HTML element or using other identifying attributes.

2. Retrieve the parameter from the URL: Use JavaScript to extract the parameter value from the URL. You can use the `window.location` object and techniques like URL parsing or regular expressions to get the parameter value.

3. Modify the view: Once you have the parameter value, you can use JavaScript to adjust the view of the list web part accordingly. For example, you can change the list view, apply filters, or modify other display settings based on the retrieved parameter.
