在 ctrl2 中,我想为 ctrl1
中的表单触发表单提交操作如何在angularJs中实现这一目标?
答案 0 :(得分:0)
您可以在按钮单击时发出一个事件,然后使用rootscope来向下广播 - 然后ctrl1可以听取这个提交表单作为回应。

您可以从第二个控制器发出事件并在第一个控制器中收听它。
function CtrlOne($rootScope)
{
$rootScope.$on('submitEvent', function(event, args) {
//submit your form here
});
}
function CtrlTwo($scope,$rootScope)
{
$scope.submit=function(){
$rootScope.$emit('submitEvent', args);
}
}

<div ng-controller="CtrlOne">
<form name="form1" ng-submit="submitForm()">
<input type="text" name="email" />
</form>
</div>
<div ng-controller="CtrlTwo">
<button ng-click="submit()"> Submit </button>
</div>

您可以使用$rootScope
或services
或event brodcasting
app.controller('ctrl2',['$scope','$rootScope',function($scope,$rootScope) {
$scope.submitForm = $rootScope.mainSubmit();
}]);
app.run(function($rootScope){
$rootScope.mainSubmit =function(){
console.log("hey");
};
})
