问题 I've been working on a HTML page that I want to convert into an image. I have been using the html2canvas and canvas2image scripts and taken this code http://jsfiddle.net/8ypxW/3/ here that has allowed me to create a button that will take a screenshot and download my HTML page as an image. The problem I'm having is that my downloaded screenshot image shows my text but not my image, even though they are from the same origin. I'm not sure if it's a problem with my HTML, HTML2canvas or

html2canvas offscreen

问题 In using html2canvas, I have a stack of DOM objects (relative positioned div's that contain various things), that I wish to create individual thumbnails for. So if there are ten divs, I will create ten thumbnails. Some of these objects will be offscreen --each of these divs are in a single, encompassing div called "mainDiv". I iterate through the divs within mainDiv and execute the html2canvas on each of them individually. For those that are onscreen, this works fine. Those that are offscreen

问题 I use html2canvas (from html2canvas.hertzen.com) to capture screenshot. I got this strange error like this: The code of my webpage is put on one host, say Host A.
