跟AI学一手之前端导出

现在前端因为有 blob 的 api，导文件太方便了，不用后端配合，直接从前端导出文件，而且只要你知道文件格式，理论上可以导出任何格式。下面是一个导出 csv 的函数，比较简单

const exportLogs = () => {
              if (logs.value.length === 0) {
                alert("暂无数据可导出");
                return;
              }
              
              const headers = ["日志类型", "操作用户", "IP地址", "位置", "浏览器", "操作时间", "备注"];

              
              const rows = logs.value.map((log) => {

                return [
                  log.log_type || "",
                  log.username || "",
                  log.ip_addr || "",
                  log.location || "",
                  log.browser || "",
                  log.tm || "",
                  log.comment || "",
                ];

              });
              
              const csv = [
                headers.join(","),
                ...rows.map(row => row.map(cell => `"${cell || ''}"`).join(","))
              ].join("\n");
              
              const blob = new Blob(["\ufeff" + csv], {
                type: "text/csv;charset=utf-8;",
              });
              const link = document.createElement("a");
              link.href = URL.createObjectURL(blob);
              link.download = `审计日志_${formatDate(new Date(), "YYYY-MM-DD")}.csv`;
              link.click();
            };
