splitText (method )

Owning interface and usage:  
Text.splitText(offset)

Member of these other interfaces:  
CDATASection

Description:  
Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings. After being split, this node will contain all the content up to the offset point. A new node of the same type, which contains all the content at and after the offset point, is returned. If the original node had a parent node, the new node is inserted as the next sibling of the original node. When the offset is equal to the length of this node, the new node has no data.

Parameters:  
unsigned offset  -  The 16-bit unit offset at which to split, starting from 0.

Returns:  
Text -  The new node, of the same type as this node.

Exceptions:  
DOMException INDEX_SIZE_ERR
Raised if the specified offset is negative or greater than the number of 16-bit units in data.
DOMException NO_MODIFICATION_ALLOWED_ERR
Raised if this node is readonly.
