![]() Javascript Generate Random Id How To Use OtherHere youll learn how to use other methods of the Math object to get a whole number in the range of your choice. If not, there are plenty of great sites out there to learn from. At this point you need to choose a value for the highest point in your range. All you do now is multiply your generated random number by your desired high point. So; Math.random() 7 essentially. Fortunately, JavaScript provides another useful method of the Math object called floor(). ![]() The line in your script should now look something like Math.floor(Math.random() 6). ![]() You do this simply by adding onto zero to bring you to your desired lowest point. To show this clearly, we can change our old 0-6 script into the 1-7 script weve always dreamt of; Math.floor(Math.random() 6 1). You dont need any extra brackets because multiplication is always performed before addition. The full line, if youve been following the example, should look like this: alert(Math.floor(Math.random() 6 1));. It looks confusing but hopefully it isnt so much now. You could make a script using either of these too but floor() seems the most intuitive. However, there are algorithms that can yield results very close to random. Adding semicolons also insure that you follow JavaScripts coding conventions. By continuing to use our site, you agree to our cookie policy.
