-- 作者:科明123 -- 发布时间:2024/8/14 16:23:00 -- Uploader 中止上传 在change事件里监听图片日期,若不符合条件,则中止该文件上传或删除该文件,这段代码应怎样写? const up1 = document.getElementById(\'up1\'); up1.addEventListener(\'change\', getdatetimeoriginal,false); function getdatetimeoriginal(e){
var file = e.target.files[0];
var OriginalDate;
EXIF.getData(file, function(){
OriginalDate = EXIF.getTag(this, \'DateTimeOriginal\');
});
if (!CheckDate(OriginalDate)){
//中止上传
} } |

-- 作者:科明123 -- 发布时间:2024/8/14 16:45:00 -- 测试了一下,这个change事件是发生在调文件到UPLOADER图像分组框中发生的,此时还没有提交。这个过程能否中止文件调入UPLOADER分组框? |
-- 作者:有点蓝 -- 发布时间:2024/8/14 17:21:00 -- 3楼是接收,不是上传。前端上传的代码在什么地方? |

-- 作者:有点蓝 -- 发布时间:2024/8/14 17:33:00 -- 使用js变量判断 const up1 = document.getElementById(\'up1\'); up1.addEventListener(\'change\', getdatetimeoriginal,false); var isupload = true; function getdatetimeoriginal(e){

-- 作者:科明123 -- 发布时间:2024/8/14 18:25:00 -- 这样处理会取消所有文件的上传,能不能排除不符合要求的文件,再提交其余符合要求的文件? |
-- 作者:有点蓝 -- 发布时间:2024/8/15 8:36:00 -- 试试,下面,如果不行就没有办法,只能使用第三方的上传组件,或者使用原生的file input标签自己做 if (!CheckDate(OriginalDate)){
//中止上传 e.target.files.splice(0, 1); } |
