我想用颜色选择器设置文本的颜色。找到了一个很好的小敲击装订器，但无法使其正常工作。
HTML：
<div class="myPicker" data-bind="jqColorPicker: coverTextColor, colorPickerOptions: { value: coverTextColor}"></div>
<span class="title" data-bind="text: title, style: { color: coverTextColor}">blahblah</span>
Bindingshandler＆amp;视图模型：
ko.bindingHandlers.jqColorPicker = {
init: function (element, valueAccessor, allBindingsAccessor) {
// set default value
var value = ko.utils.unwrapObservable(valueAccessor());
$(element).val(value);
//initialize datepicker with some optional options
var options = allBindingsAccessor().colorPickerOptions || {};
$(element).colorPicker(options);
//handle the field changing
ko.utils.registerEventHandler(element, "change", function () {
var observable = valueAccessor();
observable($(element).val());
});
//handle disposal (if KO removes by the template binding)
ko.utils.domNodeDisposal.addDisposeCallback(element, function () {
$(element).colorPicker("destroy");
});
},
update: function (element, valueAccessor, allBindingsAccessor) {
var value = ko.utils.unwrapObservable(valueAccessor());
$(element).val(value);
$(element).change();
}
};
viewModel = function(){
var self = this;
self.coverTextColor = ko.observable('green');
self.title = ko.observable('Hi there!');
};
ko.applyBindings( new viewModel() );
任何帮助表示感谢。
