Detailed Description

WebEngineScriptCollection handles a user scripts collection, which is injected in the JavaScript engine during the loading of web content.

Use WebEgineView.userScripts and WebEngineProfile.userScripts to access the collection of scripts associated with a single page or number of pages sharing the same profile.

The collection of user script objects in QML can be created for a set of user script objects by simple assignment to WebEngineScriptCollection.collection property or by WebEngineScriptCollection methods.

Note: The new user script can be instantiated with JavaScript dictionaries when using collection property.

See the following code snippets demonstrating the usage:

  • collection property with JavaScript dictionaries
    var scriptFoo = { name: "Foo",
                    sourceUrl: Qt.resolvedUrl("foo.js"),
                    injectionPoint: WebEngineScript.DocumentReady }
    
    webEngineView.userScripts.collection = [ scriptFoo, scriptBar ];
  • collection property with user script object as value type
    var script = WebEngine.script()
    script.name = "FOO"
    webEngineView.userScripts.collection = [ script ]
  • user script collection insert method can be used only with value type or list of value types
    var script = WebEngine.script()
    script.name = "FOO"
    webEngineView.userScripts.insert(script)
    
    var list = [ script ]
    webEngineView.userScripts.insert(list)
