Question

我有一个按钮（锚标签）：

/* Custom Config */
var ProgramID = '1111';

/* Default Config */
var webpack = require('webpack');
var path = require('path');
var polyfill = require("babel-polyfill");
var ExtractTextPlugin = require("extract-text-webpack-plugin");

var BUILD_DIR = path.resolve(__dirname, 'build/Programs/' + ProgramID);
var APP_DIR = path.resolve(__dirname, 'src/import');

module.exports = {
  entry: [
    'babel-polyfill',
    'webpack-dev-server/client?http://localhost:8080/',
    APP_DIR + '/import.js'
  ],
  output: {
    path: BUILD_DIR + '/',
    filename: '/js/bundle.js',
    publicPath: '../Programs/' + ProgramID
  },
  module: {
    loaders: [{
      test: /\.jsx?$/,
      loaders: ['react-hot', 'babel?presets[]=es2015,presets[]=react,plugins[]=transform-runtime'],
      exclude: /node_modules/
    }, {
      test: /\.css$/,
      loader: ExtractTextPlugin.extract("style-loader", "css-loader")
    }, {
      test: /\.scss$/,
      loaders: ["style", "css", "sass"]
    }, {
      test: /\.(png|woff|woff2|eot|ttf|svg|jpg|gif)$/,
      loader: 'file-loader?name=/images/[name].[ext]'
    }]
  },
  plugins: [
    new ExtractTextPlugin("style.css"),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin()
  ],
  process: function(path, filename) {
    if (filename.indexOf('node_modules') === -1) {
      path = babelJest.process(path, filename);
      path = webpackAlias.process(path, filename);
    }
    return path;
  },
  externals: {
        "jquery": "jQuery"
    }
};

我正在使用<a href ng-if="!isLogin" class="dropdown-toggle" data-toggle="dropdown"> <b class="white-link">Login</b> <span class="caret white-link"></span></a>自定义css类将颜色应用于登录按钮。

当我将鼠标悬停在登录按钮上时，css类仅应用于按钮，但是我想将它应用于按钮和插入符号，当我将鼠标悬停在插入符号上时，同样适用。我怎么做角度？

Answer 1

这与javascript和angular
无关只需定义你的css类

<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<style>
   .white-link:hover { color: red !important}
</style>

<a href  class="dropdown-toggle" data-toggle="dropdown" >
  <span class="white-link">
<b>Login</b> 
<span class="caret"></span></span></a>

Answer 2

您可以使用ngMouseover，ngMouseleave和ngClass指令在悬停时应用css并在mouseleave上删除它。

<button ng-class="{'white-link': login}" ng-mouseover="login = true" ng-mouseleave="login = false">Login</button>
<span ng-class="{'white-link': login}" ng-mouseover="login = true" ng-mouseleave="login = false">Text</span>

在悬停到登录按钮和范围元素时，white-link类将同时应用于按钮和范围。
