Insert HTML into iframe
提问by RailsSon
I am creating a in browser HTML editor. I am using the syntax highlighter called Code Mirror which is very good.
我正在创建一个浏览器 HTML 编辑器。我正在使用名为 Code Mirror 的语法荧光笔,它非常好。
My setup is an iframe that holds a view of the page which is being edited and a textarea which the plain text HTML sits which the user edits.
我的设置是一个 iframe,它包含正在编辑的页面的视图和一个文本区域,纯文本 HTML 位于用户编辑的位置。
I am trying to insert the edited HTML from the textarea into the iframe which displays they rendered HTML.
我试图将编辑过的 HTML 从 textarea 插入到 iframe 中,该 iframe 显示它们呈现的 HTML。
Is this possible? I have tried the following:
这可能吗?我尝试了以下方法:
HTML setup:
HTML设置:
<iframe id="render">
</iframe>
<textarea id="code">
HTML WILL BE
HERE
</textarea>
<input type="submit" id="edit_button" value="Edit" />
JQuery Setup:
jQuery 设置:
$('#edit_button').click(function(){
var code = editor.getCode(); // editor.getCode() is a codemirror function which gets the HTML from the text area
var iframe = $('#render');
iframe.html(code)
})
This does not seem to load the HTML into the iframe, is there a special method to insert HTML into a iframe or is this not possible?
这似乎没有将 HTML 加载到 iframe 中,是否有一种特殊的方法可以将 HTML 插入到 iframe 中,或者这是不可能的?

You can do it all on one line with jquery
您可以使用 jquery 在一行中完成所有操作
$("iframe").contents().find('html').html("Your new HTML");
See working demo here http://jsfiddle.net/dWpvf/972/

Replace "iframe" with "#render" for your example. I left in "iframe" so that other users can reference the answer.
对于您的示例,将“iframe”替换为“#render”。我留在“iframe”中,以便其他用户可以参考答案。

try
尝试
iframe[0].documentElement.innerHTML = code;
Assuming that the url to the iframe is from the same domain as the webpage.
假设 iframe 的 url 来自与网页相同的域。
