javascript - 切换链接以使其可点击/不可点击

Question

我已成功使链接可点击，但如何使它们再次恢复为不可点击状态？

HTML

<div id="links">
    http://google.com <br>
    http://facebook.com <br>
    http://youtube.com
</div>
<button>Toggle!</button>

JavaScript

$.fn.replaceUrl = function() {  
    var regexp = /((ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?)/gi;
    this.each(function() {
        $(this).html(
            $(this).html().replace(regexp,'<a href="$1">$1</a>')
        );
    });
    return $(this);
}

$('button').click(function(){
    $('div').replaceUrl();
});

检查这个 fiddle :http://jsfiddle.net/2ttWS/

代码:

$.fn.replaceUrl = function() {
    if($(this).find('a').length > 0) {
        $(this).find('a').each(function() {
           $(this).replaceWith($(this).text());
        });
    }
    else {
        var regexp = /((ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?)/gi;
        this.each(function() {
            $(this).html(
            $(this).html().replace(regexp, '<a href="$1">$1</a>'));
        });
    }
    return $(this);
}
