Javascript Calculator
While working on a side project, for which I found a small amount of time to work on. I created this rather simple and basic calculator, made with jQuery (Of course).
You can view the calculator here: jQuery Calculator
It was rather simple to build, and I don't even think that the source is really worth describing or going into detail with. The only thing I think is worth mentioning is the use of the 'eval' function, which allowed me to dynamically create javascript on the fly and take the result of it.
In this case, I passed in the Left and Right values along with the operator and simply stored the output. For example, if you typed in "55", hit "+" and then entered "100". I simply call:
-
var result = eval('55' + '+' + '100');
Which resulted in the numeric value of 155, of course.
