问题描述
I am trying to integrate a cropping tool to my website (js plugging resizing cropping images canvas). This tool will let the user crop an image, open it in a new browser page, and give him the capacity to save the new image into the disk.
裁剪代码如下:
crop = function(){
//Find the part of the image that is inside the crop box
var crop_canvas,
left = $('.overlay').offset().left - $container.offset().left,
top = $('.overlay').offset().top - $container.offset().top,
width = $('.overlay').width(),
height = $('.overlay').height();
crop_canvas = document.createElement('canvas');
crop_canvas.width = width;
crop_canvas.height = height;
crop_canvas.getContext('2d').drawImage(image_target, left, top, width, height, 0, 0, width, height);
var newWindow = window.open(crop_canvas.toDataURL("image/png"));
}
现在，我想将一些HTML内容附加到newWindow正文中，但是它不起作用.我试图在 window.open 命令之后添加以下内容:
Now i want to append some HTML content to newWindow body, but it does not work. I tried to add the following after window.open command:
var text = document.createTextNode('Hello World !');
newWindow.document.body.appendChild(text);
但是什么都没有添加到新页面吗?
But nothing is added to the new page ?
如何使用父页面中的脚本将内容添加到新页面的正文中?(HTML内容，甚至是一些JavaScript代码)
How can add stuff to the body of the new page using the script from the parent page ? (Html content and even some javascript code)
谢谢！
推荐答案
var dataUri = crop_canvas.toDataURL("image/png"),
newWindow = window.open("about:blank");
newWindow.document.write("<!DOCTYPE html>\n<body><img src='" + dataUri + "' /></body>");
var text = document.createTextNode('Hello World !');
newWindow.document.body.appendChild(text);
