使用ng-include时丢失范围

问题描述

  var mainModule = angular.module（'lpConnect'，[]）。 $（'/ home'，{template：'views / home.html'，控制器：HomeCtrl，'b $ b config（['$ routeProvider'，function（$ routeProvider）{
 $ routeProvider。 }）。
 when（'/ admin'，{template：'views / admin.html'，controller：AdminCtrl}）。
 otherwise（{redirectTo：'/ connect'}）; 
}]）; 
  

首页HTML：

 < div ng-include src =views.partial1>< / div> 
  

partial1 HTML：

 < form ng-submit =addLine（）> 
< input type =textng-model =lineTextsize =30placeholder =在此输入您的信息> 
< / form> 
  

HomeCtrl ：

 函数HomeCtrl（$ scope，$ location，$ window，$ http，Common）{
 ... 
 $ scope。 views = {
 partial1：views / partial1.html
}; 
 
 $ scope.addLine = function（）{
 $ scope.chat.addLine（$ scope.lineText）; 
 $ scope.lines.push（{text：$ scope.lineText}）; 
 $ scope.lineText =; 
}; 
 ... 
 
  

在 addLine function $ scope.lineText 是 undefined ，可以通过添加 ng-controller =HomeCtrl to partial1.html ，但它会导致控制器被调用两次。我在这里错过了什么？

解决方案

这是因为 ng-include 它创建一个新的子范围，所以 $ scope.lineText 不会改变。我认为这个指的是当前范围，所以应该设置 this.lineText 。

I have this module routes:

var mainModule = angular.module('lpConnect', []).
    config(['$routeProvider', function ($routeProvider) {
    $routeProvider.
        when('/home', {template:'views/home.html', controller:HomeCtrl}).
        when('/admin', {template:'views/admin.html', controller:AdminCtrl}).
        otherwise({redirectTo:'/connect'});
}]);

Home HTML:

<div ng-include src="views.partial1"></div>

partial1 HTML:

<form ng-submit="addLine()">
    <input type="text" ng-model="lineText" size="30" placeholder="Type your message here">
</form>

HomeCtrl:

function HomeCtrl($scope, $location, $window, $http, Common) {
    ...
    $scope.views = {
        partial1:"views/partial1.html"
    };

    $scope.addLine = function () {
        $scope.chat.addLine($scope.lineText);
        $scope.lines.push({text:$scope.lineText});
        $scope.lineText = "";
    };
...
}

In the addLine function $scope.lineText is undefined, this can be resolved by adding ng-controller="HomeCtrl" to partial1.html, however it causes the controller to be called twice. What am I missing here?

解决方案

This is because of ng-include which creates a new child scope, so $scope.lineText isn’t changed. I think that this refers to the current scope, so this.lineText should be set.
