我有一个文件,其中使用了jQuery,并且仅用于测试目的。
正如您所看到的,
我做错了什么?
(function($) {
"use strict"; // Start of use strict
// Configure tooltips for collapsed side navigation
$('.navbar-sidenav [data-toggle="tooltip"]').tooltip({
template: '<div class="tooltip navbar-sidenav-tooltip" role="tooltip" style="pointer-events: none;"><div class="arrow"></div><div class="tooltip-inner"></div></div>'
})
// Toggle the side navigation
$("#sidenavToggler").click(function(e) {
e.preventDefault();
$("body").toggleClass("sidenav-toggled");
$(".navbar-sidenav .nav-link-collapse").addClass("collapsed");
$(".navbar-sidenav .sidenav-second-level, .navbar-sidenav .sidenav-third-level").removeClass("show");
});
// Force the toggled class to be removed when a collapsible nav link is clicked
$(".navbar-sidenav .nav-link-collapse").click(function(e) {
e.preventDefault();
$("body").removeClass("sidenav-toggled");
});
// Prevent the content wrapper from scrolling when the fixed side navigation hovered over
$('body.fixed-nav .navbar-sidenav, body.fixed-nav .sidenav-toggler, body.fixed-nav .navbar-collapse').on('mousewheel DOMMouseScroll', function(e) {
var e0 = e.originalEvent,
delta = e0.wheelDelta || -e0.detail;
this.scrollTop += (delta < 0 ? 1 : -1) * 30;
e.preventDefault();
});
// Scroll to top button appear
$(document).scroll(function() {
var scrollDistance = $(this).scrollTop();
if (scrollDistance > 100) {
$('.scroll-to-top').fadeIn();
} else {
$('.scroll-to-top').fadeOut();
}
});
// Configure tooltips globally
$('[data-toggle="tooltip"]').tooltip()
// Smooth scrolling using jQuery easing
$(document).on('click', 'a.scroll-to-top', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: ($($anchor.attr('href')).offset().top)
}, 1000, 'easeInOutExpo');
event.preventDefault();
});
})(jQuery); // End of use strict
而 webpack 报错:
Failed to compile.

我已经在 index.js
中添加了 jquery
,但为什么它还是会报错呢?
我是用 https://github.com/facebook/create-react-app 创建我的 reactjs 应用的。
index.js
的代码如下:
import React from 'react';
import ReactDOM from 'react-dom';
/* Import css */
import 'font-awesome/css/font-awesome.css';
import './index.css';
/* Import javascript */
import 'bootstrap';
import 'jquery';
import './SbAdmin/js/sb-admin';
import App from './App/AppContainer.bs';
import registerServiceWorker from './registerServiceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();
正如您所看到的,
jQuery
已被导入。我做错了什么?
// eslint-disable-line no-undef
