问题
How would I split a node/element at a position (selection).
Example I have this markup:
<p>This is <a href="">a te|st</a>, you like?</p>
(this pipe represents the position/selection)
I want to convert it to:
<p>This is <a href="">a te</a></p>|<p><a href="">st</a>, you like?</p>
Maintaining the selection.
Any ideas?
I and using the Rangy library, and also jQuery, but can use raw JS if applicable.

You could do this by creating a range that extends from the caret to the point immediately after the paragraph and using its extractContents() method.
Live demo: http://jsfiddle.net/timdown/rr9qs/2/
Code:
var sel = rangy.getSelection();
if (sel.rangeCount > 0) {
// Create a copy of the selection range to work with
var range = sel.getRangeAt(0).cloneRange();
// Get the containing paragraph
var p = range.commonAncestorContainer;
while (p && (p.nodeType != 1 || p.tagName != "P") ) {
p = p.parentNode;
}
if (p) {
// Place the end of the range after the paragraph
range.setEndAfter(p);
// Extract the contents of the paragraph after the caret into a fragment
var contentAfterRangeStart = range.extractContents();
// Collapse the range immediately after the paragraph
range.collapseAfter(p);
// Insert the content
range.insertNode(contentAfterRangeStart);
// Move the caret to the insertion point
range.collapseAfter(p);
sel.setSingleRange(range);
}
}
