dropzone.js图片上传acceptedMimeTypes [英] dropzone.js image upload acceptedMimeTypes

问题描述

我使用dropzone.js插件将图像上传器添加到我的应用程序中。我知道这可能是一个非常基本的问题，所以我想要做的是限制文件扩展名。这适用于单个文件扩展名，

 < script type =text / javascript> 
 Dropzone.options.dropzone = {
 accept：function（file，done）{
 console.log（file）; 
 if（file.type！=image / jpeg）{
 done（Error！This type of files are not accepted）; 
} 
 else {done（）; } 
} 
} 
< / script> 
  

所以我的问题是如何添加多个文件扩展名，即 image / jpeg ， image / png ？

谢谢
<您可以添加更多的扩展到如果，如下所示：

  if（file.type！=image / jpeg&& file.type！=image / png）{
  

这将检查文件类型是否与您指定的所有类型不同。对于通过支票的文件，它必须与image / jpeg和image / png不同

I am using the dropzone.js plugin to add an image uploader to my application. I know this is probably a really basic question so apologies but what I want to do is limit the file extensions. This works for a single file extension,

<script type="text/javascript">
   Dropzone.options.dropzone = {
        accept: function(file, done) {
            console.log(file);
            if (file.type != "image/jpeg") {
                done("Error! Files of this type are not accepted");
            }
            else { done(); }
        }
    }
 </script>

So my question is how to add multiple file extensions, i.e. image/jpeg, image/png?

Thanks

解决方案

You could add more extensions to your if, like so:

if (file.type != "image/jpeg" && file.type != "image/png") {

This will check if the file type is different from ALL of the types you specify. For a file to pass the check, it has to be different from image/jpeg AND image/png

Update

I would advise to look at enyo's answer since he is the author of Dropzone.
