继上一篇基于jQuery UI Autocomplete的AngularJS 指令(directive)扩展,在这里发布一个AngularJS的Slider扩展。如果你还不了解AngularJS话的情参见AngularJs - Javascript MVC 框架,Angular-Bootstrap和Compiler以及Google-AngularJS官方文档.
jsfiddle演示:http://jsfiddle.net/whitewolf/vNfsm/20/embedded/:
html:
- <div ng-app="app" ng-controller="test">
- <green-slider style="margin:20px;"></green-slider>
- <green-slider ng-model="value" style="margin:20px;height:200px;" id="w1" class="22" ng-change="change();" range="min" min="10" max ="80" step ="1" orientation="vertical" ></green-slider>
- <br/>
- value:`value`;
- <input ng-model="value" maxlength="2" style="width:25px;"/>
- </div>
js:
- var prefixed = "green";
- var appMoule = angular.module('app', []);
- var slider = function() {
- var linkFun = function($scope, element, attrs) {
- $slider = jQuery(element);
- var option = attrs;
- var tryPrseInt = function(key, option) {
- if (option[key]) {
- option[key] = parseInt(option[key]);
- }
- };
- tryPrseInt("min", option);
- tryPrseInt("max", option);
- tryPrseInt("step", option);
- option = jQuery.extend({
- value: $scope[option.ngModel],
- change: function(event, ui) {
- if (attrs.ngModel && ui.value != $scope[attrs.ngModel]) {
- var express = attrs.ngModel + ' = ' + ui.value;
- $scope.$apply(express);
- if (attrs.ngChange) {
- $scope.$eval(attrs.ngChange);
- }
- }
- }
- }, option);
- $slider.slider(option);
- //back
- if (option.ngModel) {
- $scope.$watch(option.ngModel, function(val) {
- if (val != $slider.slider("value")) {
- $slider.slider("value", val);
- }
- });
- }
- console.log(attrs);
- };
- return {
- restrict: 'E',
- replace: true,
- transclude: false,
- template: '<div />',
- link: linkFun
- };
- };
- appMoule.directive(prefixed + "Slider", slider);
- //test controller:测试代码
- var test = function($scope) {
- $scope.value = 10;
- $scope.change = function() {
- console.log("change", this.value);
- };
- };
- appMoule.controller("test", test);
同时有什么问题请多多交流,功能进步
