Change all links at once

Question

Is there any way i can change all links at once under option tag?
For Example:

<select size="1" name="links" onchange="window.location.href=this.value;">
<option value=" http://website.com/1001/">Blue</option>
</select><br>

 <select size="1" name="links" onchange="window.location.href=this.value;">
<option value=" http://website.com/2001/">Red</option>
</select><br>

<select size="1" name="links" onchange="window.location.href=this.value;">
<option value=" http://website.com/3001/">Green</option>
</select>

.... And so on around 100 links .
Now i want to change link website.com to m.website.com furthur link remains same. Like m.website.com/1001 , m.website.com/1002
