深入研究HTML5实现图片压缩上传功能

var dom = { "fileToUpload": $self.find(".fileToUpload"),

"thumb": $self.find(".thumb"), "progress": $self.find(".upload-progress")

}; var image = new Image(),

canvas = document.createElement("canvas"), ctx = canvas.getContext('2d');

var funs = { setImageUrl: function(url) {

image.src = url; },

bindEvent: function() { console.log(dom.fileToUpload)

dom.fileToUpload.on("change", function() { funs.fileSelect(this);

}); },
