打包h5，出错，因为添加了监听
cc.EventListener.create({
event: cc.EventListener.TOUCH_ONE_BY_ONE,
swallowTouches: true,
onTouchBegan:function (touch, event) {
},
onTouchEnded: function (touch, event) {
})
出现
Error: IE8 will parse trailing commas in array and objects literals incorrectly.If you are targeting newer versions of JS,set the appropriate language_in option.
event:cc.EventListener.TOUCH_ONE_BY_ONE
说event是关键字。
怎么解决
