js 正则表达式 ，除去字符串中 font-family:xxxx 这样的字符传

function removeFontFamily(contnet){//remove repeatvar unique = function(arr) {    var result = [], hash = {};    for (var i = 0, elem; (elem = arr[i]) != null; i++) {        if (!hash[elem]) {            result.push(elem);            hash[elem] = true;        }    }    return result;}//var arr = contnet.match(/(font-family:[^><;"]*(;)?)/ig);arr = unique(arr);for(var i=0;i<arr.length;i++){ console.log(arr[i]);var reg = new RegExp(arr[i], "ig");contnet = contnet.replace(reg,"");}return contnet;}
