语境：

我正在使用 barba js 在 wordpress 网站上进行一些页面转换，每次页面更改时我都必须加载一些脚本，主要是来自 wordpress 插件的一些 js/css 文件，以便 ajax 搜索工作。我做了一个接收脚本 src/href 然后将元素添加到头部的方法。问题可能出在我糟糕的代码结构或我不知道老实说的库中。

问题：

该代码只运行我调用的第一个脚本，正如我上面所说，我不知道它是来自我的代码还是来自库！

代码：

起初我以为我需要一些超时才能使代码工作，所以我这样做了

{
                namespace: 'product',
                beforeEnter(data) {
                    //loads styles
                    setTimeout(reloadStyles('ivory-search-styles-css', 'wp-content/plugins/add-search-to-menu/public/css/ivory-search.css?ver=4.4.7'), 500)

//loads javascript files.
                    setTimeout(reloadScripts('wp-content/plugins/add-search-to-menu/public/js/ivory-ajax-search.js?ver=4.4.7'), 800)
                    setTimeout(reloadScripts('/wp-content/plugins/add-search-to-menu/public/js/ivory-search.js?ver=4.4.7'), 1000)
                    setTimeout(reloadScripts('/wp-content/plugins/contact-form-7/includes/js/scripts.js?ver=5.1.7'), 1200)

                    searchTranslations()
                    // refresh breadcrumbs
                    let documentAjax = (new DOMParser()).parseFromString(data.next.html, 'text/html');
                    let breadcrumbsAjax = documentAjax.querySelector('.breadcrumbs')
                    let breadcrumbs = document.querySelector('.breadcrumbs')
                    breadcrumbs.innerHTML = breadcrumbsAjax.innerHTML;


                    logoPath.style.fill = "black"

                }
            },

这是原始代码（没有超时）：

{
                namespace: 'product',
                beforeEnter(data) {

                    reloadStyles('ivory-search-styles-css', '/wp-content/plugins/add-search-to-menu/public/css/ivory-search.css?ver=4.4.7')

                    reloadScripts('/wp-content/plugins/add-search-to-menu/public/js/ivory-ajax-search.js?ver=4.4.7')
                    reloadScripts('/wp-content/plugins/add-search-to-menu/public/js/ivory-search.js?ver=4.4.7')
                    reloadScripts('/wp-content/plugins/contact-form-7/includes/js/scripts.js?ver=5.1.7')

                    searchTranslations()
                    // refresh breadcrumbs
                    let documentAjax = (new DOMParser()).parseFromString(next.html, 'text/html');
                    let breadcrumbsAjax = documentAjax.querySelector('.breadcrumbs')
                    let breadcrumbs = document.querySelector('.breadcrumbs')
                    breadcrumbs.innerHTML = breadcrumbsAjax.innerHTML;


                    logoPath.style.fill = "black"

                }
            },

提前致谢 ！

编辑：这是方法

    const reloadScripts = (scrpSrc) => {

        console.log("Script loaded:  " + scrpSrc)

        var wpcf7 = { "apiSettings": { "root": "/wp-json\/contact-form-7\/v1", "namespace": "contact-form-7\/v1" } };

        let head = document.getElementsByTagName('head')[0]
        let script = document.createElement('script')

        script.src = scrpSrc;


        if (script != undefined || script != null) {
            head.removeChild(script)
            head.appendChild(script)
        }
        else head.appendChild(script)

    }

尝试进行以下修改。主要变化是您在删除和添加脚本之前检查了错误的变量。检查头部是否包含脚本并将其删除。之后，我做了一些更改以帮助代码更具可读性和稍微干燥。

const reloadScripts = (scrpSrc) => {
        console.log("Script loaded:  " + scrpSrc)
        const wpcf7 = { 
          "apiSettings": { 
            "root": "/wp-json\/contact-form-7\/v1", 
            "namespace": "contact-form-7\/v1" 
            } 
          };
        let head = document.querySelector('head'),
          headScript = head.querySelector('[src="='+ scrpSrc +'"]'),
          script = document.createElement('script');
         //checking if head already has a script
        if (headScript != undefined || headScript != null) {
            head.removeChild(headScript);
        }
        //then always do this piece. not DRY to have it inside and outside the if stmt
        script.src = scrpSrc;
        head.appendChild(script)
    }
