Replacing\Changing Alpha in RGBA JavaScript
javascript, regex, replace, rgba
Solution
I don't get your logic but you can do this :
color = color.replace(/[\d\.]+\)$/g, 'A)')
What it matches :
- `[\d\.]+` : a combination of `.` and digits
- `\)` : the end parenthesis
- `$` : the end of the string (you can remove it if you don't want to ensure it's the end of the string)
Problem
I'm trying to change the Alpha in RGBA, from some reason replace acts strange and instead of resulting with: "rgba(30, 43, 2, A)" i end up with: "A". Here is the code: ``` var color="rgba(30, 43, 2, 0.498039)"; color = color.replace(/^.*,(.+)\)/gi,"A"); alert(color); ``` JS Fiddle Demo
