forEach的用法

this.listData.forEach(ele => {

if (ele.imgUrl) {

num++

axios({

url: `/file/views/${ele.imgUrl}`,

methods: 'get',

responseType: 'blob',

}).then((data) => {

let blob = data.data;

let src = window.URL.createObjectURL(blob)

// ele.imgSrc = src

this.$set(ele,'imgSrc',src)

console.log(data)

num--

})

}

})
