1. var test1="http://www.wljcz.com/My first/";  
2. var nn=encodeURI(test1);  
3. var now=decodeURI(test1);  
4. document.write(nn+ "<br />");  
5. document.write(now);  
6.   
7. var test1="http://www.wljcz.com/My first/";  
8. var bb=encodeURIComponent(test1);  
9. var nnow=decodeURIComponent(bb);  
10. document.write(bb+ "<br />");  
11. document.write(nnow);  
14. 其运行结果为：
