js正則過濾敏感詞成星號

function filterKeyword() {
            console.log("1212");
            var pcontent =$("#pContainer").html();
            //console.log(pcontent);
            var wordArr = ["驚訝", "惡意", "裂縫", "黑線", "紅暈", "臉頰", "長眼"];
            wordArr.forEach(function (item, index, array) {
                if (pcontent.indexOf(item) != -1) {
                    var reg = new RegExp(item, "g");
                    pcontent = pcontent.replace(reg, '<font color="red">*</font>');
                }
            });
            $("#pContainer").html(pcontent);
        }
