Leveraging vanilla JavaScript within durandal.js

Currently working with durandal.js and I need to trigger a plugin on page load.

This is how it can be done in plain JavaScript:

$('.testingShifter').shapeshift();

I am wondering if there is a specific durandal (knockout) binding that I can utilize to execute this JavaScript when the page loads.

Answer №1

If you want to add a method to your viewmodel, simply create an attached method or you can opt to make a custom binding for it.

For example:

define(function () {

var vm = {
        activate: activate, 
        attached: attached 
}

var activate = function () {
    //Do vm activation here
};

var attached = function(view) {

        //do any dom stuff here.    
        var $testingShifter = $(view).find('.testingShifter'); 
        $testingShifter.shapeshift(); 
};
return vm; 

});

OR

    ko.bindingHandlers.shapeShift= {
    init: function (element, valueAccessor, allBindingsAccessor, viewModel) {
        var allBindings = allBindingsAccessor();

        var $testingShifter = $(element);
        $testingShifter.shapeshift(); 

        });
    }
}

The custom binding handler would be called using:

data-bind="shapeshift:value"

on an html element.

I hope this explanation helps you out.
