Binding a promise handler function to an object

rated 0 times [ 198] [ 7] / answers: 1 / hits: 38012 / 11 Years ago, wed, may 8, 2013, 12:00:00

I have some code like:

var bar = foo().then(function success(value) {

  // compute something from a value...

}, function failure(reason) {

  // handle an error...

});

How do I bind the failure function to the this object in the context of bar. I know I will have to use myFunc.bind(this) but what do I substitute in place of myFunc?

You can use bind like this:

var bar = foo().then(function success(value) {

  // compute something from a value...

}, function failure(reason) {

  // handle an error...

}.bind(this));
