首先写一个loading.js文件
import { Loading } from 'element-ui';
let loadingCount = 0;
let loading;
const startLoading = () => {
loading = Loading.service({
lock: true,
text: '加载中……',
background: 'rgba(0, 0, 0, 0.7)'
});
};
const endLoading = () => {
loading.close();
};
export const showLoading = () => {
if (loadingCount === 0) {
startLoading();
}
loadingCount += 1;
};
export const hideLoading = () => {
if (loadingCount <= 0) {
return;
}
loadingCount -= 1;
if (loadingCount === 0) {
endLoading();
}
};
然后添加全局拦截
// ...
import { showLoading, hideLoading } from './loading';
/* 请求拦截器(请求之前的操作) */
ajax.interceptors.request.use((req) => {
showLoading();
return req;
}, err => Promise.reject(err));
/* 请求之后的操作 */
ajax.interceptors.response.use((res) => {
hideLoading();
return res;
return Promise.reject(res);
}, (err) => {
hideLoading();
return Promise.reject(err);
});
