问题描述
我正在使用Dropzonejs插件。上传文件时,我想检查图像尺寸(宽度和高度)以及文件大小。我设法检查了尺寸和文件大小,但是当我将两者结合使用时,效果并不理想。
I'm using the Dropzonejs plugin. I want to check the image dimension (width and height) and also the file size when a file is uploaded. I managed to check the dimension and file size but when I combined both of them, it didn't work well.
var maxImageWidth = 2500,
maxImageHeight = 2500;
Dropzone.options.formUserEdit = {
maxFilesize: 2,
acceptedFiles: 'image/*',
success : function(file, Response){
var obj = JSON.parse(Response);
$('#form-user-edit').append('<input type="hidden" name="userprofile" data-ori="'+file.name+'" value="'+obj.filename+'" />');
$('.error-msg').remove();
},
init: function() {
this.on("thumbnail", function(file) {
if (file.width > maxImageWidth || file.height > maxImageHeight) {
file.rejectDimensions();
else {
file.acceptDimensions();
}
})
},
accept: function(file, done) {
file.rejectDimensions = function() {
done("Please make sure the image width and height are not larger than 2500px.");
};
file.acceptDimensions = done;
}
}
如果:
-
上传大尺寸图片:它接受功能
upload big dimension image: it accepts the function
上传小尺寸图片,但2MB:它将返回 file.acceptDimensions不是函数
或不会成功
upload small dimension image but more than 2MB: it will return file.acceptDimensions is not a function
or will not go to success
推荐答案
如果有人仍然需要答案。
In case someone still need the answer.
init: function() {
this.on("thumbnail", function(file) {
if (file.width > maxImageWidth || file.height > maxImageHeight) {
file.rejectDimensions();
else {
if(file.size < 1024*1024*2/*2MB*/)
{
file.acceptDimensions();
}
}
})
},
