vue-i18n 怎么用在data属性上

用computed绑定数据:

 

    
    

        
{{$t('lang.step')}} {{index + 1}}
        

            {{item.stepDec}}
        
    



//js
computed: {
    stepLists() {
        return [
            {
                img: require('../assets/img/home/step1_pic.png'),
                stepDec: this.$t('lang.homePage.stepLists[0]')
            },
            {
                img: require('../assets/img/home/step2_pic.png'),
                stepDec: this.$t('lang.homePage.stepLists[1]')
            }
        ]
    }
},
