AngularJS Bootstrap



  • Bootstrap 定义和使用

    AngularJS 的首选样式表是 BootstrapBootstrap 是目前最受欢迎的前端框架。
    将样式表 <link> 复制粘贴到您的 <head>中,然后再粘贴所有其他样式表以加载CSS。
    <head>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css">
    </head>
    
    
    下面演示了是一个完整的 HTML 实例, 使用了 AngularJS 指令和 Bootstrap 类:

    AngularJS 指令 描述
    $scope.fName 模型变量 (用户名)
    $scope.lName 模型变量 (用户姓)
    $scope.passw1 模型变量 (用户密码 1)
    $scope.passw2 模型变量 (用户密码 2)

    $scope.error 如果 passw1 不等于 passw2 设置为 true
    $scope.incomplete 如果每个字段都为空(length = 0)设置为 true
    $scope.editUser 设置模型变量
    $scope.watch 监控模型变量
    $scope.test 验证模型变量的错误和完整性
