like below fixes the issue I'm trying to add a class (.active) to a text field once the user starts typing. I got it to work somewhat with the following code, but for some reason the .active class is not applied immediately when the user starts typing, it's only applied after a second letter has been typed. Any ideas? , You want keyup here, updated based on comments:
code :
$(document).ready(function() {    
    $('.field').live('keydown', function(){
      $(this).addClass('active');
    }).live('keyup', function() {
      $(this).toggleClass('active', $(this).val() != '');
    });
});

With these it helps If you want the transparent effect like in photoshop, you need to use an alpha channel. See this question.
If you want to composite the image with another background, you can use the alpha matting formula I = aF+(1-a)B, where a the alpha, F the foreground and B the background. Like this:
code :
ex_alpha = np.repeat(alpha[:, :, np.newaxis], 3, axis=2)
output = (foreground*ex_alpha) + (1-ex_alpha)*background

I think the issue was by ths following , Your event.target.value(/\d/g, "#") should be event.target.value = event.target.value.replace(/\d/g, "#");. This should get you closer. – Tyler Roper

fixed the issue. Will look into that further Perhaps things have changed since this question was asked, because Jason P's first suggestion appears to work now.
