用Jquery调用Angular函数
当文本框中的数据如何调用angularfunction？ 这是我的代码
HTML

当文本框中的两个select选项插入数据要调用强制文本上的searchfunction
如果您将一个ID标记附加到与ng-controller相同的DOM元素，则可以访问angular元素的作用域：
DOM：
<div id="mycontroller" ng-controller="mycontroller"></div>
你的控制器：
function mycontroller($scope) { $scope.myfunction = function() { //do some stuff here } }
在jQuery中，你这样做，它将访问该控制器并调用该函数：
angular.element('#mycontroller').scope().myfunction();
记得打电话
angular.element('#mycontroller').scope().$apply()
如果你在myfunction的作用域内更新了一个函数variables，那么它将无法工作（谢谢@andersh）
如果你在你的代码中使用这样的东西
<div id="mycontroller" ng-controller="mycontroller as child"></div>
代替
<div id="mycontroller" ng-controller="mycontroller"></div>
访问将是
angular.element('#mycontroller').scope().child.myFunction();
代替
angular.element('#mycontroller').scope().myFunction();
在任何情况下，你也需要这个电话
angular.element('#mycontroller').scope().$apply();
用于访问控制器的范围元素
angular.element(document.getElementById('controllerId')).scope().scope_variable_array.push(item);
用于访问控制器function
angular.element(document.getElementById('controllerId')).scope().function_name();
controllerId：在HTML中定义ng控制器的标记ID
我使用这样的东西：
var $scope = angular.element($('[ng-controller]')).scope()
并操作$ scopevariables。 您可以检查控制台
我参考这个post ，把函数赋值给全局对象window 。
// In angularJS script $scope.foo = function() { console.log('test'); }; $window.angFoo = function() { $scope.foo(); $scope.$apply(); }; // In jQuery if (window.angFoo) { window.angFoo(); }
