О чём код?
let callbacks = [] function loadedTinymce() { // to fixed https://github.com/PanJiaChen/vue-element-admin/issues/2144 // check is successfully downloaded script return window.tinymce } const dynamicLoadScript = (src, callback) => { const existingScript = document.getElementById(src) const cb = callback || function() {} if (!existingScript) { const script = document.createElement('script') script.src = src // src url for the third-party library being loaded. script.id = src document.body.appendChild(script) callbacks.push(cb) const onEnd = 'onload' in script ? stdOnEnd : ieOnEnd onEnd(script) } if (existingScript && cb) { if (loadedTinymce()) { cb(null, existingScript) } else { callbacks.push(cb) } } function stdOnEnd(script) { script.onload = function() { // this.onload = null here is necessary // because even IE9 works not like others this.onerror = this.onload = null for (const cb of callbacks) { cb(null, script) } callbacks = null } script.onerror = function() { this.onerror = this.onload = null cb(new Error('Failed to load ' + src), script) } } function ieOnEnd(script) { script.onreadystatechange = function() { if (this.readyState !== 'complete' && this.readyState !== 'loaded') return this.onreadystatechange = null for (const cb of callbacks) { cb(null, script) // there is no way to catch loading errors in IE8 } callbacks = null } } } export default dynamicLoadScript
