ck-editor不能在谷歌浏览器粘贴图片，但是在火狐可以，修改config.js

CKEDITOR.on("instanceReady", function(event) {
event.editor.on("beforeCommandExec", function(event) {
// Show the paste dialog for the paste buttons and right-click paste
if (event.data.name == "paste") {
event.editor._.forcePasteDialog = true;
}
// Don't show the paste dialog for Ctrl+Shift+V
if (event.data.name == "pastetext" && event.data.commandData.from == "keystrokeHandler") {
event.cancel();
}
})
});
