uni-app null is not an object (evaluating 'this.$emit') __ERROR

uni-app 中组件里使用this.$emit

直接写在@click="this.$emit（‘“voucherChange”，{item,index}）"中报错

uni-app null is not an object (evaluating 'this.$emit') __ERROR

 

解决方法

@click="voucherChange(item,index)"

在methods里写

voucherChange(item,index){
　　this.$emit('voucherChange',{item,index})
}
