vue项目中导出Excel文件功能的前端代码实现

// 导出数据
exportData() {
window.location.href = `/oes-content-manage/role/export-roles?size=${this.totalCount}&sidx=roleName&sord=desc&roleId=${this.searchForm.roleId}`;
},

// 查询结果导出
exportResult() {
let key;
let param = {};
for (key in this.exportParam) {
if (key == 'page' || key == 'rows') {
continue;
} else {
param[key] = this.exportParam[key]
}
}
exportexcl(param).then(res => {
var blob = new Blob([res.data], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}); // application/vnd.openxmlformats-officedocument.spreadsheetml.sheet这里表示xlsx类型
var downloadElement = document.createElement('a');
var href = window.URL.createObjectURL(blob); // 创建下载的链接
downloadElement.href = href;
downloadElement.download = '导出数据.xlsx'; // 下载后文件名
document.body.appendChild(downloadElement);
downloadElement.click(); // 点击下载
document.body.removeChild(downloadElement); // 下载完成移除元素
window.URL.revokeObjectURL(href); // 释放掉blob对象
})
},

// 查询结果导出
export function exportexcl(params) {
  return axios.post(servers + '/program/export', params, {
    responseType: 'blob'
  });
}
