    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

    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.

    Parameters

    parentNode
    The caret location will be within this node.
    offset
    The offset in parentNode to which the selection will be collapsed.

    Examples

    /* Place the caret at the beginning of an HTML document's body. */

    window.getSelection().collapse(body,0);
