            <div data-role="footer" id="footer_main">................. .................</div>
        </div>
    </body>

CSS

.one::selection {
       background-color:#3C3;
}

The above code didnt work. Can somebody please help me with this?

回答1:

If your mobile browser does not support ::selection pseudo-element, then what you can do is use JavaScript to trigger text selection change on the element and the replace the selected text in the div with a span with specified color.

JQUERY

$(function() {
    $('div.one').mouseup( function() {
        var mytext = selectHTML();
        $('.one span').css({"color":"red"});
    });
});

function selectHTML() {
    try {
        if (window.ActiveXObject) {
            var c = document.selection.createRange();
            return c.htmlText;
        }

        var nNd = document.createElement("span");
        var w = getSelection().getRangeAt(0);
        w.surroundContents(nNd);
        return nNd.innerHTML;
    } catch (e) {
        if (window.ActiveXObject) {
            return document.selection.createRange();
        } else {
            return getSelection();
