“未捕获的TypeError:$不是函数"在WordPress中 [英] "Uncaught TypeError: $ is not a function" in WordPress

问题描述

关于此错误，有些问题，但是我找不到关于它们的任何解决方案.我正在开发WordPress主题，在入队脚本期间出现此错误:

There are some questions about this error, but I couldn't find any solutions on them. I'm developing a WordPress theme and during the enqueue script this error came up:

Uncaught TypeError: $ is not a function
    at components.js?ver=4.8:65
    at components.js?ver=4.8:95

这是我的排队代码添加到functions.php中:

here is my enqueue code add to the functions.php:

function goc_scripts() {
    wp_enqueue_style( 'goc-style', get_stylesheet_uri() );

    wp_enqueue_style( 'socicon', get_stylesheet_directory_uri() . '/css/socicon.css', array() );

    if ( is_singular() && comments_open() && get_option( 'thread_comments' ) ) {
        wp_enqueue_script( 'comment-reply' );
    }
}
add_action( 'wp_enqueue_scripts', 'goc_scripts' );

这里是发生错误的代码components.js(第65行和第95行):

and here is the code components.js where the error happens (line 65 and line 95):

var LayoutHeader = function () {
    var offset = parseInt($('.c-layout-header').attr('data-minimize-offset') > 0 ? parseInt($('.c-layout-header').attr('data-minimize-offset')) : 0);
    var _handleHeaderOnScroll = function () {
        if ($(window).scrollTop() > offset) {
            $("body").addClass("c-page-on-scroll");
        } else {
            $("body").removeClass("c-page-on-scroll");
        }
    }

    var _handleTopbarCollapse = function () {
        $('.c-layout-header .c-topbar-toggler').on('click', function (e) {
            $('.c-layout-header-topbar-collapse').toggleClass("c-topbar-expanded");
        });
    }

    return {
        //main function to initiate the module
        init: function () {
            if ($('body').hasClass('c-layout-header-fixed-non-minimized')) {
                return;
            }

            _handleHeaderOnScroll();
            _handleTopbarCollapse();

            $(window).scroll(function () {
                _handleHeaderOnScroll();
            });
        }
    };
}();

推荐答案

对此有两种解决方案:

#1

#1

将代码中的所有$替换为jQuery.

Repalce all $ to jQuery in your code.

#2

#2

还是一种简单的方法.

只需将jQuery作为global variable分配给$，就像在.js文件顶部一样，则所有代码都可以正常工作.

just assign jQuery to $ as a global variable like following on the top of your .js file and all your code will work fine.

var $ = jQuery;

我希望这对您有用.
