It isn't possible to write into a document from an asynchronously-loaded

 

今天遇到了一個問題：

通過document.write() 輸出一個iframe 標簽的時候 提示錯誤

Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened. 

在chrom上面就提示”Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened. “

 

解決方法  

var iframeStr = document.createElement('iframe');
document.getElementsByTagName('body')[0].appendChild(iframeStr)；
