将图片从其他网站拖放到我的网站 [英] Drag and Drop images from another website to mine

问题描述

我跑了一个快速的google和so搜索，发现类似的问题，但没有一个是良好的形式，大多数是旧的，看起来被遗弃（没有答案，没有一段时间的意见）。所以这里是...

I ran a quick google and SO search and found similar questions but none were well formed and most were old and looked abandoned (no answers, and no comments for a while). So here goes...

我想要能够收集从另一个网站被丢弃到我的网站上的图像的url（只有url）..我有两个chrome窗口打开，窗口A有我的应用程序，窗口B有它的imgur我打开一个图像点击并拖动到我的窗口，放开我现在我需要知道的图像上的url页）。

I want to be able to collect the url (only the url) of an image being dropped onto my site from another website.. (i.e. I have two chrome windows open. Window A has my application in it. Window B has imgur in it. I open an image click and drag it to my window and let go. Now I need to know the url of the image dropped on my page).

这是我使用的本地文件的代码。

Here is the code I was working with for local files.

$(document).on('drop', function(e) {
    var data = e.dataTransfer || e.originalEvent.dataTransfer;
    console.log(data); // data.files is empty
    e.preventDefault();
    return false;
});​

再次，我不想上传任何东西..我不想做任何想象。 ..我只需要知道图像被丢弃在另一个网站的页面上的位置。

Again I do not want to upload anything.. i'm not trying to do anything fancy... I just need to know the location of the image being dropped on the page from another website.

推荐答案

尝试以下操作： http： /jsfiddle.net/2Jet2/70/

$(document).on('dragover', function(e) {
     e.preventDefault();
});
$(document).on('drop', function(e) {
    e.preventDefault();
    e.originalEvent.dataTransfer.items[0].getAsString(function(url){
        alert(url);
    });
});​

我得到http://static3.flattr.net/thing/image/9/4/5/5/0/huge.png?1326712342当我从另一个浏览器窗口拖动图片时。

I get "http://static3.flattr.net/thing/image/9/4/5/5/0/huge.png?1326712342" When I dragged that image from another browser window.

.getAsString 接受一个回调，一旦它被调用

.getAsString takes a callback which gets the url as argument once it's called

在firefox上无效

Doesn't work on firefox
