Selection.collapse()

The Selection.collapse() method collapses the current selection to a single point. The document is not modified. If the content is focused and editable, the caret will blink there.

Syntax

sel.collapse(node, offset);

Parameters

node: The caret location will be within this node. This value can also be set to null — if null is specified, the method will behave like Selection.removeAllRanges(), i.e. all ranges will be removed from the selection.
offset Optional: The offset in node to which the selection will be collapsed. If not specified, the default value 0 is used.

Examples

/* Place the caret at the beginning of an HTML document's body. */
var body = document.getElementsByTagName("body")[0];
window.getSelection().collapse(body,0);
