Question

I’m handling the dblclick event on a span in my web app. A side effect of a double click is that it selects text on the page. How can I prevent this selection from happening?

Answer 1

function clearSelection() {
    if(document.selection && document.selection.empty) {
        document.selection.empty();
    } else if(window.getSelection) {
        var sel = window.getSelection();
        sel.removeAllRanges();
    }
}

You can also apply these styles to the span for all non-IE browsers and IE10:

span.no_selection {
    user-select: none; /* standard syntax */
    -webkit-user-select: none; /* webkit (safari, chrome) browsers */
    -moz-user-select: none; /* mozilla browsers */
    -khtml-user-select: none; /* webkit (konqueror) browsers */
    -ms-user-select: none; /* IE10+ */
}
