Dropzone max file size exceeded event
提问by AVM
I am using dropzone in my form for image upload. I would like to show an alert message and remove the file added when the user chooses a file above the configured limit. Here is my configuration:
我在表单中使用 dropzone 进行图像上传。当用户选择超出配置限制的文件时，我想显示一条警报消息并删除添加的文件。这是我的配置：
Dropzone.options.myDropzone = {
paramName: 'file',
url: "http://someurl",
clickable: true,
enqueueForUpload: true,
autoProcessQueue: false,
uploadMultiple: true,
parallelUploads: 5,
maxFiles: 1,
maxFilesize: .06,
maxThumbnailFilesize: .06,
acceptedMimeTypes: 'image/*',
addRemoveLinks: true,
dictDefaultMessage: 'Drag your images here',
init: function() {
console.log('init');
this.on("maxfilesexceeded", function(file){
alert("No more files please!");
this.removeFile(file);
});
}
};
I tried to register a listener for 'maxfilesizeexceeded' event, but it didnt fire. I would like to take similar action as for 'maxfilesexceeded'. Is this possible?
我试图为 'maxfilesizeexceeded' 事件注册一个监听器，但它没有触发。我想对“maxfilesexceeded”采取类似的行动。这可能吗？

I have just tried it out on my script using the Error event. This way I get an Error Message and the File gets removed again. Is this what you are looking for?
我刚刚使用 Error 事件在我的脚本上进行了尝试。这样我会收到一条错误消息，并且文件再次被删除。这是你想要的？
this.on("error", function(file, message) {
alert(message);
this.removeFile(file);
});
