How can I active QuickEdit with Javascript?

Question

we're customizing a lot of customers sharepoint sites and we need to turn on/off QuickEdit multiple times, I want to create a Bookmarklet to achieve this, but the setting can't be found.

I've tried by changing the SchemaXML of the list, but it doesn't do anything.. Thanks for any advice!

var context = SP.ClientContext.get_current();
var web = context.get_web();
var listTitle = 'MyList';
var list = web.get_lists().getByTitle(listTitle);
var url = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getByTitle('" + listTitle + "')";
var xmlDoc;

// Load the schema XML for the list
context.load(list, 'SchemaXml');
context.executeQueryAsync(function() {
    var schemaXml = list.get_schemaXml();

    // Convert schema XML string to XML DOM object
    var parser = new DOMParser();
    xmlDoc = parser.parseFromString(schemaXml, 'text/xml');

    // Get the List node
    var listNode = xmlDoc.getElementsByTagName('List')[0];

    // Add or update the EnableGridEditing attribute to the List node
    listNode.setAttribute('DisableGridEditing', 'FALSE');

    
    var newSchemaXml = xmlDoc.documentElement.outerHTML;
    console.log(newSchemaXml);
    
    var postBody = JSON.stringify({ '__metadata': { 'type': 'SP.List' }, 'SchemaXml': newSchemaXml });

    $.ajax({
        url: url,
        type: "POST",
        data: postBody,
        headers: {
            "X-HTTP-Method":"MERGE",
            "accept": "application/json;odata=verbose",
            "content-type": "application/json;odata=verbose",
            "X-RequestDigest": $("#__REQUESTDIGEST").val(),
            "IF-MATCH": "*"
        },      
        
        success: function () {
            console.log("List schema updated successfully");
        },
        error: function (err) {
            console.log(err.responseText);
        }
    });
    
    

}, function(sender, args) {
  console.log(args.get_message());
});

As far I know Quick Edit is not property of the view so edit view property will not help you.
You did not write whether you are looking for Quick edit in classic experience or modern experience (where is called Grid view). But if you are looking for something for classic experience you can try this bookmarklet for enter Quick edit:

javascript:void((function(){var loc = location.href; loc.indexOf("?") == -1 ? (location.href = loc+"?ShowInGrid=True") : (location.href = loc+"&ShowInGrid=True")})());

Please mark this as answer it helps you.
