问题
There is very strange problem with variable in action script. I use it (variable) to dinamically change width of progress bar in my mp3 player, here is code:
filledProgress.width = Math.round (progressPercent * 1.56);
it works very good in the beginning, but after some time it stops, by stops I mean, filledProgress.width doesn't want to change its value from 0, although on the right part of expression is always some result, I even created different variable, to check whether it will get value from:
Math.round (progressPercent * 1.56);
And it works perfectly well, but filledProgress.width didn't change at all, however, after i reload and clear cash in my browser, it again starts to work, and again after short period of time stops.
What can it be?
回答1:
This behavior may occur due to removed event listener.
Check where you remove event listener in which you update width.
