getselection

问题 I have got a Javascript code, which works well for modern browsers: var offset = getSelection().anchorOffset; var node = getSelection().anchorNode; How can I get the same result on IE 8, which does not have window.getSelection() method? 回答1: There is a solution.

问题 If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret?

问题 I am using the following function to get the selected text (i.e. text selected by the user) in a contenteditable div. This works perfect in IE 9 but not in IE 8, Firefox or Chrome (both latest versions). Can someone here help me to modify this in a way that it works at least in Firefox and IE 8 as well (Chrome is not a must) ?
