希望您能够帮助我.我在mac的Dock上有一个奇怪的org.apache.catalina.startup.Bootstrap图标.我和Lion一起使用10.7.2版本.我使用这个:在startup.sh和shutdown.sh导出JAVA_OPTS =" - Djava.awt.headless = true"但是遇到了同样的问题.提前致谢.

也许我错过了某种属性,但是我正在关注这个项目,我在控制器中遇到了这个错误.

TypeError: loginService.signin is not a function

这是我的controller.js

angular.module('appcontrollers', []).controller('LoginController', ['$rootScope', '$scope', '$http', '$location', '$localStorage', 'loginService',  
        function ($rootScope, $scope, $http, loginService) {

        $scope.signin = function() {

            console.log("username: " + $scope.username);
            console.log("pass: " + $scope.password);

            var formData = {
                username: $scope.username,
                password: $scope.password
            };

            // ERROR IN THIS LINE
            loginService.signin(formData, function(res) {
                console.log("asdf");
                if (res.type == false) {
                    console.log(res.data);
                } else {
                    $localStorage.token = res.data.token;
                    console.log("Window location /");
                }
            }, function() {
                $rootScope.error = "Error en el logueo del …

我在尝试创建virtualenv文件夹时遇到问题,因为我的终端说virtualenv似乎没有安装.

我做了什么:

sudo pip install virtualenv

有这个回应:

我的应用程序上没有一个菜单栏,当用户导航时我需要绘制,我还有其他组件也需要绘制.我可以实现这个routerLinkActive吗？

menu.html

<menu>
  <a routerLink="page1" routerLinkActive="active">
      option1
  </a>
  <a routerLink="page2" routerLinkActive="active">
      option2
  </a>
</menu>

这个菜单很棒.但我要问的是如何利用其他HTML标签中的routerLinkActive属性.喜欢:

main.html中

<main>
    <span class="title" routerLinkActive="active">My sub child part</span>
</main>

如何设置 mat-autocomplete 以获得选定的选项 ID？

<mat-form-field>
    <input type="text" matInput 
        [formControl]="autocompleteControl" 
        [matAutocomplete]="auto">
        <mat-autocomplete #auto="matAutocomplete">
            <mat-option *ngFor="let book of books" [value]="book.id"> <!-- THIS SHOW THE ID ON THE UI -->
                {{ book.title }}
            </mat-option>
        </mat-autocomplete>
</mat-form-field>

如果我在[value]属性处将“book.title”更改为“book.id”，UI 会在自动完成输入上显示 ID，这并不好。我应该把“book.id”放在哪里，以便稍后在我的component.ts上询问他？
