如何在Nativescript-Vue中更改WebView上的Src

Question

我想用SideDrawer制作Android应用，从中为WebView选择不同的站点。需要做什么以反映WebView中Src中的更改？谢谢！

    <RadSideDrawer ref="drawer">
        <StackLayout ~drawerContent backgroundColor="#ffffff">
            <Label class="drawer-header" text="Menu"/>
            <Label class="drawer-item" text="Gmail" @tap="onTap01"/>
            <Label class="drawer-item" text="Youtube" @tap="onTap02"/>                
        </StackLayout>

        <GridLayout ~mainContent columns="*" rows="*">
            <WebView ref="myWebView" src="https://google.com/" />
        </GridLayout>
    </RadSideDrawer>


    methods: {

    onTap01() {
         this.$refs.MyWebView.src="https://gmail.com";
         console.log( this.$refs.MyWebView.src); //It's changed
         this.$refs.drawer.nativeView.closeDrawer();
    },
