Yes, it is possible to load an empty <iframe>
(with no src
specified) and later apply content to it using script.
是的,可以加载一个空的<iframe>
(没有src
指定),然后使用脚本将内容应用到它。
See: http://api.jquery.com/jquery-wp-content/themes/jquery/js/main.js(line 54 and below).
请参阅:http: //api.jquery.com/jquery-wp-content/themes/jquery/js/main.js(第 54 行及以下)。
Or simply try:
或者干脆试试:
<iframe></iframe>
document.querySelector('iframe')
.contentDocument.write("<h1>Injected from parent frame</h1>")

Sure. You can get a reference to the iframe
's document
object with
当然。您可以获得对iframe
'sdocument
对象的引用
var doc = iframe.contentDocument;
and then you can create and add elements like you do in the current document.
然后您可以像在当前文档中一样创建和添加元素。
If the iframe doesn't have a src
attribute, it will still contain an empty document. I believe though that at least older IE versions require the src
attribute to be set, otherwise the iframe won't have a document.
如果 iframe 没有src
属性,它仍将包含一个空文档。我相信至少旧的 IE 版本需要设置src
属性,否则 iframe 将没有文档。

Mixing best answers in javascript and jQuery, I come up with this solution for each iframe
in a page:
将 javascript 和 jQuery 中的最佳答案混合在一起,我为iframe
页面中的每一个都提出了这个解决方案:
<div class="iframewrapper ws-s-top mb-50" data-content="<!DOCTYPE html><html><head></head><body><p>Hello world</p></body></html>">
<iframe frameborder="0" src=""></iframe>
</div>
$(".iframewrapper").each(function(){
var html = $(this).attr("data-content");
var iframe = $(this).find('iframe');
var context = iframe[0].contentDocument.write(html);
iframe[0].contentWindow.document.close(); //without this line, page loading animations won't go away!
});
