如果你使用 webPack 和 Typescript，你可以这样做：
在您的 vendor.ts 文件中导入 jquery：
/ RxJS.
import "rxjs";
// Angular 2.
import "@angular/common";
import "@angular/compiler";
import "@angular/core";
import "@angular/http";
import "@angular/platform-browser";
import "@angular/platform-browser-dynamic";
import "@angular/router";
// Reflect Metadata.
import "reflect-metadata";
// Other vendors for example jQuery, Lodash or Bootstrap
// You can import js, ts, css, sass, ...
import "jquery"; //<-- HERE IS JQUERY
import "bootstrap/dist/js/bootstrap";
import "bootstrap/dist/css/bootstrap.min.css";
import "angular2-toaster/lib/toaster.css";
import "angular2-toaster/angular2-toaster";
import "ng2-slim-loading-bar";
import "ng2-slim-loading-bar/style.css";
import "ng2-modal";
import "ng2-bs3-modal/ng2-bs3-modal";
然后在您的 webpack.dev.js 中使用插件将其导入每个组件中，而无需手动导入：
var ExtractTextPlugin = require("extract-text-webpack-plugin");
var webpack = require("webpack");
var HtmlWebpackPlugin = require("html-webpack-plugin");
var CleanWebpackPlugin = require('clean-webpack-plugin');
var path = require('path');
module.exports = {
entry: {
"polyfills": "./polyfills.ts",
"vendor": "./vendor.ts",
"app": "./app/main.ts",
},
resolve: {
extensions: ['', '.ts', '.js', '.json', '.css', '.scss', '.html']
},
output: {
path: "./app_build",
filename: "js/[name]-[hash:8].bundle.js"
},
devtool: 'source-map',
module: {
loaders: [
{
loader: "babel-loader",
// Skip any files outside of your project's `src` directory
//include: [
// "app_build",
//],
exclude: [
path.resolve(__dirname, "node_modules")
],
// Only run `.js` and `.jsx` files through Babel
test: /\.js/,
// Options to configure babel with
query: {
plugins: ['transform-runtime', 'babel-plugin-transform-async-to-generator'],
presets: ['es2015', 'stage-0'],
}
},
{
test: /\.ts$/,
loader: "ts"
},
{
test: /\.html$/,
loader: "html"
},
//{
// test: /\.(png|jpg|gif|ico|woff|woff2|ttf|svg|eot)$/,
// loader: "file?name=assets/[name]-[hash:6].[ext]",
//},
{
test: /\.(png|jpg|gif|ico)$/,
//include: path.resolve(__dirname, "assets/img"),
loader: 'file?name=/assets/img/[name]-[hash:6].[ext]'
},
{
test: /\.(woff|woff2|eot|ttf|svg)$/,
// exclude: /node_modules/,
loader: 'file?name=/assets/fonts/[name].[ext]'
},
// Load css files which are required in vendor.ts
{
test: /\.css$/,
loader: "style-loader!css-loader"
},
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('css!sass')
},
]
},
plugins: [
new ExtractTextPlugin("css/[name]-[hash:8].bundle.css", { allChunks: true }),
new webpack.optimize.CommonsChunkPlugin({
name: ["app", "vendor", "polyfills"]
}),
new CleanWebpackPlugin(
[
"./app_build/js/",
"./app_build/css/",
"./app_build/assets/",
"./app_build/index.html"
]
),
// inject in index.html
new HtmlWebpackPlugin({
template: "./index.html",
inject: "body"
}),
// JQUERY PLUGIN HERE <-- !!! HERE IS PLUG IN
new webpack.ProvidePlugin({
jQuery: 'jquery',
$: 'jquery',
jquery: 'jquery'
})
],
devServer: {
//contentBase: path.resolve(__dirname, "app_build/"),
historyApiFallback: true,
stats: "minimal"
}
};
现在在您的代码 .ts 中的任何地方，您都可以像这样使用 jquery：
import { Component, AfterViewInit, ElementRef } from '@angular/core';
@Component({
selector: 'about',
template: require('./about.component.html'),
styles: [String(require('./about.component.scss'))]
})
export default class AboutComponent implements AfterViewInit {
calendarElement: any;
constructor(private elementRef: ElementRef) { }
ngAfterViewInit() {
this.calendarElement = jQuery(this.elementRef.nativeElement);
}
}
