最近在做一個需求,遇到了一個問題,html頁面中引入一堆js,導致html頁面代碼看起來特別不美觀,於是想着如何把所有的js引入到一個js內,然后只在html頁面引入一個js,這樣頁面看起來就簡潔多了,於是就做了如下的內容:
在shuilangyizu.js中引入多個其他js的代碼:
var script1=document.createElement('script');//創建script標簽節點 script1.setAttribute('type','text/javascript');//設置script類型 script1.setAttribute('src','http://pv.sohu.com/cityjson?ie=utf-8');//設置js地址 document.body.appendChild(script1);//將js追加為body的子標簽 //判斷script1是否加載成功 script1.onload=script1.onreadystatechange=function(){ //如果script1加載成功則創建script2引入,這樣就不會由於后面的js依賴前面的js導致后面的js先加載而導致程序報錯 if(!this.readyState||this.readyState=='loaded'||this.readyState=='complete'){ var script2=document.createElement('script'); script2.setAttribute('type','text/javascript'); script2.setAttribute('src','http://www.shuilangyizu.top/js/jquery-2.1.4.js'); document.body.appendChild(script2); script2.onload=script2.onreadystatechange=function(){ if(!this.readyState||this.readyState=='loaded'||this.readyState=='complete'){ var script3=document.createElement('script'); script3.setAttribute('type','text/javascript'); script3.setAttribute('src','http://www.shuilangyizu.top/js/clipboard.min.js'); document.body.appendChild(script3); script3.onload=script3.onreadystatechange=function(){ if(!this.readyState||this.readyState=='loaded'||this.readyState=='complete'){ var script4=document.createElement('script'); script4.setAttribute('type','text/javascript'); script4.setAttribute('src','http://www.shuilangyizu.top/js/jquery-weui.js'); document.body.appendChild(script4); script4.onload=script4.onreadystatechange=function(){ if(!this.readyState||this.readyState=='loaded'||this.readyState=='complete'){ var script5=document.createElement('script'); script5.setAttribute('type','text/javascript'); script5.setAttribute('src','http://www.shuilangyizu.top/js/wechat.js'); document.body.appendChild(script5); } } } } } } } }
然后將shuilangyizu.js引入html頁面:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>js中引入多個js測試</title> </head> <body ontouchstart> <div align="center" style="margin-top: 50px;"> <span class="ceshi">ceshi</span> </div> <script type="text/javascript" src="http://www.shuilangyizu.top/js/shuilangyizu.js"></script> </body> </html>
這樣就成功了!!!
