zaparker / KnockoutBootstrapModalBinding
Last active August 29, 2015 14:10
Custom knockout binding for the Bootstrap modal plugin. Includes bindings to the modal options, all the modal events, and an extra 'visible' binding to toggle the modal.
ko.bindingHandlers.modal = {
init: function (element, valueAccessor, allBindingsAccessor, viewModel, bindingContext) {
var value = valueAccessor();
var valueUnwrapped = ko.unwrap(value);
var options = valueUnwrapped.options;
options.show = valueUnwrapped.visible && ko.unwrap(valueUnwrapped.visible);
$(element).modal(options);
$(element).on('show.bs.modal', function() {
if(valueUnwrapped.visible) {
if(typeof(valueUnwrapped.visible) === 'function') valueUnwrapped.visible(true);

Array.prototype.forEach = function (fnAction) {
var l = this.length;
for (var i = 0; i < l; ++i) {
fnAction(this[i]);
}
}
// returns an array containing the items matching the filter
Array.prototype.where = function (fnFilter) {
