How could I code a button to call the following JSON data?

Question

I want to use the following button to get JSON data

<button>Get JSON data</button>

Using this JavaScript

    var t = jsPlumbToolkit.newInstance();

    var data = t.exportData({
      type:"myFormat",
      parameters:{
        importantNumber:34,
        somePrefix:"foo-"
      }
    });

How could I get the button to call this?

There are several ways of doing this in JavaScript. You could start with something as simple as defining a function in javascript and calling it each time the button is clicked:

<button onclick="get_json_data();">Get JSON data</button>

function get_json_data(){
    var t = jsPlumbToolkit.newInstance();

    var data = t.exportData({
        type:"myFormat",
        parameters:{ importantNumber:34, somePrefix:"foo-" } }
    );
    //Whatever you want to do here
}

I stress that maybe this is not the best way of doing this, but it's the easiest to understand. Hope this helps.
