我一直在尝试使用Bootstrap 4.1.1和Angular 6在带有折叠菜单和下拉链接的Navbar上工作但不知何故Navbar根本不工作。我可以正确地看到元素,但它们不能按预期运行。
我使用 安装bootstrap --save'通过Angular CLI安装了Bootstrap。和Bootstrap依赖关系:' ng install jquery --save'并安装popper.js --save'
我还在package.json和angular.json中包含了Bootstrap,jquery和popper.js
的package.json:

HTML:
<nav class="navbar navbar-expand-md navbar-light bg-light">
<a href="#" class="navbar-brand">RecipeBook</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsing-nav-bar" aria-controls="collapsing-nav-bar"
aria-expanded="false" aria-label="Toggle navigation">

</button>
<div class="collapse navbar-collapse" id="collapsing-nav-bar">
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a href="#" class="nav-link">Recipes</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Shopping list</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item dropdown">
<a href="#" class="nav-link dropdown-toggle" id="dropdownMenu" data-toggle="dropdown"
aria-haspopup="true" aria-expanded="false">
Manage
</a>
<div class="dropdown-menu" aria-labelledby="dropdownMenu">
<a href="#" class="dropdown-item">Save</a>
<a href="#" class="dropdown-item">Fetch</a>
</div>
</li>
</ul>
</div>
</nav>
我更喜欢使用Bootstrap本机库而不是使用ng-bootstrap,也不喜欢在head-tag中包含CDN。
我在这里做错了吗?任何有关如何解决这个问题的建议都将受到赞赏。

我在追赶幽灵上已经损失了2个小时。注意,angular.json中有两个脚本段。在 test 下进行一项,在 build 下进行一项。您应该在构建段下添加。我正在测试中添加,因此角度看不到引导程序和popper js
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist/myBootstrapTestApp",
"index": "src/index.html",
"main": "src/main.ts",
"polyfills": "src/polyfills.ts",
"tsConfig": "src/tsconfig.app.json",
"assets": [
"src/favicon.ico",
"src/assets"
],
"styles": [
"src/styles.scss"
],
"scripts": [
"node_modules/jquery/dist/jquery.js",
"node_modules/popper.js/dist/umd/popper.min.js",
"node_modules/bootstrap/dist/js/bootstrap.js"]
},

只需在脚本中添加 umd directries popper。
"./node_modules/popper.js/dist/umd/popper.min.js",
答案 2 :(得分:1)
popper的路径应为: node_modules / popper.js / dist / umd /
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles.css"
],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/popper.js/dist/umd/popper.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]

一段时间后,我只将引导程序库放在jquery和popper命令的下面...
"styles": [
"src/styles.scss",
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/popper.js/dist/umd/popper.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js",
"node_modules/fontawesome/index.js"
]

我必须将它添加到 package.json
"dependencies": {
"core-js": "^2.5.4",
"jquery": "^3.3.1",
"popper.js": "^1.14.3",
}
"devDependencies": {
"@types/jquery": "^3.3.2",
}
这也是 angular.json
"architect": {
"build": {
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/popper.js/dist/umd/popper.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
},
确保在进行这些更改后运行 npm install。
