Calling a function in a typescript file from HTML.

Question

I'm new to HTML and Angular 2. I'm currently trying to figure out how to call a function that's inside a Typescript file from an HTML file.

Stripped down, the Typescript file (home.ts) function looks like this:

getConfigurations(sensorName: string) {
    console.log('Home:getConfigurations entered...');

    return 'sensor1';
}

In my HTML file (home.html), I would like to call 'getConfigurations' with a string parameter (right now 'getConfigurations()' returns 'sensor1' since I'm still testing things out). So, in HTML, how do I go about calling my getConfigurations method with a parameter (for simplicity - how can I call the method inside a simple div panel)? (I already have the value I want to pass in a variable called 'selectedSensor').

Answer 1

There is feature provided by angular is events binding by using you are able to call function whihc is exist in your ts file also you can use interpolation syntax of angular to call function like this : -

<button (click)='getConfigurations("parameter")'>Button Click</button>

or something like this

{{getConfigurations('parameter')}}
