制作jquery：包含重音不敏感

jQuery.expr[':'].Contains = function(a,i,m) {
    var text = jQuery(a).text().toUpperCase();
    var words = m[3].split(/\s+/);
    for(var i = 0; i < words.length; i++) {
        if (-1 == text.indexOf(words[i].toUpperCase())) {
          return false;
        }
    }
    return true;
};

我在Github上发现了这个,它对我很有用：
https://gist.github.com/oziks/3664787

jQuery.expr[':'].contains = function(a,m) {
    var rExps=[
        {re: /[\xC0-\xC6]/g,ch: "A"},{re: /[\xE0-\xE6]/g,ch: "a"},{re: /[\xC8-\xCB]/g,ch: "E"},{re: /[\xE8-\xEB]/g,ch: "e"},{re: /[\xCC-\xCF]/g,ch: "I"},{re: /[\xEC-\xEF]/g,ch: "i"},{re: /[\xD2-\xD6]/g,ch: "O"},{re: /[\xF2-\xF6]/g,ch: "o"},{re: /[\xD9-\xDC]/g,ch: "U"},{re: /[\xF9-\xFC]/g,ch: "u"},{re: /[\xC7-\xE7]/g,ch: "c"},{re: /[\xD1]/g,ch: "N"},{re: /[\xF1]/g,ch: "n"}
    ];

    var element = $(a).text();
    var search = m[3];

    $.each(rExps,function() {
        element = element.replace(this.re,this.ch);
        search = search.replace(this.re,this.ch);
    });

    return element.toUpperCase()
    .indexOf(search.toUpperCase()) >= 0;
};
