Pass Typescript Function As A Javascript Function

I use typescript with breeze. How can i pass a typescript function to executeQuery.then? class MyClass{ ... myFunc(data:any):void{ ... } doQuery():void{

Solution 1:

Use this.myFunc instead of myFunc.

It might be a context problem. Try this.myFunc.bind(this) instead of this.myFunc.

For more information about context, refer "this" and "Function.prototype.bind" article from MDN.

Solution 2:

First, this is working perfectly in my own classes. What is "not working", what error message is thrown?

Second, to be sure that "this" is my typescript class context I always use a lambda like this:

doQuery(): void {
    ...
    manager.executeQuery(query).then((data: breeze.QueryResult) => {
        this.myFunc(data);
    });
}

In this case the TS compiler produces a "var _this = this" at the beginning of the doQuery function which is your class context and converts the "this.myFunc(data)" call to "_this.myFunc(data)".

And better use type declarations like "breeze.QueryResult" instead of any.
