I want to enable a disabled element when a certain element is clicked. I know I can do this using jQuery with:
```$('#edit').click(function(event){
event.preventDefault();
$('.inputDisabled').attr('disabled', false); // Element(s) are now enabled.
});```
Why use attr when you could use prop to do this?
Why sho... | Always use the ```prop()``` method to enable or disable elements when using jQuery (see below for why).
In your case, it would be:
```$("#edit").click(function(event){
event.preventDefault();
$('.inputDisabled').prop("disabled", false); // Element(s) are now enabled.
});

What is 25/2 of a milligram?
25/2 of a milligram is what? | Here is the solution:
25/2 of a milligram is 12.5 milligram.
