让innerHTML方法添加到元素里的js可以被解析执行
<!DOCTYPE html> <html> <head> </head> <body> <div id="test" style="background:skyblue">test innerHTMLJS</div> <div onclick="say();" style="background:skyblue; margin:20px;">call say();</div> <script type="text/javascript"> function $id(id){return document.getElementById(id);} s = document.createElement('script'); s.type="text/javascript"; document.body.appendChild(s); $id('test').onclick=function(){ var el = this, HTMLString='<img src="*" style="visibility:hidden;" onerror="s.innerHTML=$id(\'ss\').innerHTML;" \/><script id="ss">function say(){alert("hi i am executed");} say();<\/script>'; el.innerHTML = HTMLString; return; }; </script> </body> </html>
