Execcommand formatblock headings in IE

Question

I want to format selected text to a heading, the way I am doing it works fine in Firefox and Google Chrome but it doesn't work in IE9, here is how I do it:

document.execCommand('formatBlock',false,'h1');

Does anyone know how to achieve the same task in Internet Explorer 9?

Answer 1

The problem seems to be one of syntax. IE expects the tag to be formatted while the other browsers don't.

See here :

In Internet Explorer, the name of the element must be placed between tag delimiters (such as <H1> ). Firefox, Opera, Google Chrome and Safari support all block elements, Internet Explorer supports only the h1 - h6, address and pre elements

Answer 2

Internet Explorer仅支持标题标记H1 - H6 ， ADDRESS和PRE ，它们还必须包含标记分隔符<和> ，例如<H1> 。

Answer 3

works perfect for me in IE9

your codes probably wrong, mines more like:

        var contentWindow = editor.contentWindow;
        contentWindow.focus();
        contentWindow.document.execCommand('formatBlock', false, '<h1>');
        contentWindow.focus();
