Hi

This is possible by javascript,You can call a javascript function by clicking a button and link.In that jave script function you write condition for color change.

for your reference you can check my previous post .

hi, i am not able to map your approach.

 

Here is my page code :

 

<table>

<tr><td>Attainment</td>
       <td>{!selectedAttainment}%</td>
</tr>

</table>

 

Here value of {!selectedAttainment} is returned from controller. If the vaue is >= 100 then i have to display it in green and if it is <100 then i have to display it in red.

 

How to achieve this?

It's simple, we just made style attribute conditional. So it will be drawn based on your variable value.

I tried this already without checking for not null.

Why you are checking for not null condition?

Is that necessary?

at the time of page load, value of your variable will be null. That's why it is required.
