How to bind "this" to "elementOpen"

[sooboy]

Hello, I am trying to bind "this" to "elementOpen"：

class Link extends Render implements ILinker {
    constructor(
        public title: string,
        public url: string,
    ) {
        super();
    }

    public click() {
        window.location.href = this.url;
    }

    public render() {
        elementOpen("a", null, null,
            "onclick", ()=>console.log("ok",this),
        );
        text("123");
        elementClose("a");
    }
}

when I click :

this is undefined,How to bind this.click to elementOpen

"onclick", ()=>this.click(),

My expression is not very accurate, I hope you can understand；
