Cocos2d html5 plist load/unload

Hello
I am developing simple game in cocos2d-js now
But I have one problem in plist load/unload
For example, I used follow code for plist load

cc.spriteFrameCache.addSpriteFrames(plistPath)
it’s good work

but problem is plist unload
I used “cc.spriteFrameCache.removeSpriteFramesFromFile(plistPath)” for it

if you have many experiences in it, pls let me know how plist file unload in cocos2d-js

Perhaps consider moving to Cocos Creator? it really simplifies a lot of the js framework stuff.
