【angularjs指令】简单的搜索框实现

/*** *(options)是否必填,类型,说明: *(ng)1 , object , angularApp对象 * *(ngScope): *(value)0 , string , 单向绑定的value对象 *(searchCall)1 , function , search回掉函数 *(keyChangeCall)1 , function , 内容变化回掉函数 */define(function(require, exports, module) {module.exports = function(param) {var options = {};if (param.directive) options.ng = paramelse options = param;if (!options.ng) return false;var domString = ["<div class='input-group input-group-sm'>","<span class='input-group-btn'>","<button class='btn btn-primary' type='button' ng-click='searchCall({value:value})'>搜索</button>","</span>","<input type='text' class='form-control' ng-model='value' ng-keyup='keyup($event)'/>","</div>"].join("");options.ng.directive('stSearch', function() {return {scope: {"searchCall": "&","value": "=","keyChangeCall": "&changeCall"},restrict: "E",template: domString,replace: true,compile: function(element, attrs, transclude) {return function($scope) {$scope.$watch('value', function(newValue, oldValue) {$scope.keyChangeCall({newValue: newValue,oldValue: oldValue});});$scope.keyup = function(e) {var keycode = window.event ? e.keyCode : e.which;if (keycode == 13) {$scope.searchCall({value: $scope.value})}}}},controller: function($scope) {}}})return true;}})

以上代码是基于seajs的简略封装，可以从第17或26行自行拆分

以下为基于seajs的使用方式

js层面引用：

require('js/search')(ng);//在init文件中引用,ng为app对象

HTML层面调用：

<div ng-controller="searchModule"><st-search search-call="searchCall(value)" value="value" change-call="keyChangeCall(newValue, oldValue)" class="col-md-4 col-md-offset-4 col-sm-12"></st-search></div>

searchModule controller：

ng.controller('searchModule', ["$scope", "$rootScope", function(scope, rootScope) {scope.searchCall = function(value) {rootScope.$broadcast('searchEvent', value);}scope.value = "石头web";//初始输入框内容scope.keyChangeCall = function() {console.log(arguments)；}}])
