decodeURIComponent 测试

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. var test1="http://www.wljcz.com/My first/";
7. var bb=encodeURIComponent(test1);
8. var nnow=decodeURIComponent(bb);
9. document.write(bb+ "<br />");
10. document.write(nnow);
11. 其运行结果为：
    http://www.wljcz.com/My%20first/
    http://www.wljcz.com/My first/
    http%3A%2F%2Fwww.wljcz.com%2FMy%20first%2F
