解决方案
不清楚您的要求是什么...但是...
如果您的JavaScript代码有问题...
1)您的if条件将永远不会通过..
if (objRad.value=="rent")
修改为
if (objRad.value=="RENT")
2)根据您的需要编写其他条件的代码.

解决方案 Not clear with what you have asked... But...
If you are having issue with your javascript code...
1) Your if condition will never be through..
if (objRad.value=="rent")
Modify it to
if (objRad.value=="RENT")
2) Write code for else condition as per your need.
