js for循环中请求改为同步方法

for (const item of checkboxRecords) {
    try {
        //await 同步
        const res = await postAction(this.url.sapCheck, item );
        if (res.message != '成功') {
            nextCheck = false
            this.$message.error(res.message);
        }
    } catch (error) {
        this.$message.error(error);
        this.confirmLoading = false;
        // 处理错误情况
        return;
    }
}
