I'm opening a new window into which I'm injecting HTML for both the body and the head. The problem is in the head section: the HTML includes both the title and the favicon but the favicon doesn't show. This is the code and the jsFiddle: https://jsfiddle.net/ufnjspgc/
function Start() {
$('#TheButton').click(function() {
var TheHeadHTML = '<link href="' + window.location.protocol + '//' + window.location.host + '/favicon.ico" rel="icon" type="image/x-icon">';
TheHeadHTML = TheHeadHTML + '<title>Title Works</title>';
var TheNewWindow = window.open();
$(TheNewWindow.document.head).html(TheHeadHTML);
});
}
$(Start);

推荐答案
You can open a new window using a data URI. Here's the code:
<input type="button" value="test" id="TheButton" />
function Start() {
$('#TheButton').click(function() {
var TheNewWindow = window.open("data:text/html;charset=utf8,<html><head><link href='" + window.location.protocol + "//" + window.location.host + "/favicon.ico' rel='icon' type='image/x-icon'><title>Title Works</title></head><body></body></html>");
});
}
$(Start);
小提琴.
基本上，数据URI 允许您在URL本身中指定内容，这样就不需要去服务器，或者就您而言，去"about:blank" 资源.由于跨源和其他方面的考虑，"about:blank"在编写脚本时可能会导致很多问题.
Basically, data URIs allow you to specify the content in the URL itself such that it doesn't need to go to a server, or, in your case, to the "about:blank" resource browsers (must) have. "about:blank" can cause a lot of problems when scripting because of cross-origin and other concerns.
如@ConnorsFan所述，此技术在IE中不起作用.如
As noted by @ConnorsFan, this technique does not work in IE. As indicated in this question by Diego Mijelshon, IE does not allow navigation to a data URI, and thus it cannot be used as the URL for a new window. Seems to work fine in recent versions of Chrome and Firefox. I'm afraid I don't have a copy of Safari on which to test.
