函数封装:
var dynamicLoading = { css: function(path){ if(!path || path.length === 0){ throw new Error(‘argument "path" is required !‘); } var head = document.getElementsByTagName(‘head‘)[0]; var link = document.createElement(‘link‘); link.href = path; link.rel = ‘stylesheet‘; link.type = ‘text/css‘; head.appendChild(link); }, js: function(path){ if(!path || path.length === 0){ throw new Error(‘argument "path" is required !‘); } var head = document.getElementsByTagName(‘head‘)[0]; var script = document.createElement(‘script‘); script.src = path; script.type = ‘text/javascript‘; head.appendChild(script); } }
使用:
//动态加载 CSS 文件 dynamicLoading.css("test.css"); //动态加载 JS 文件 dynamicLoading.js("test.js");
