我试图确定一个数字在表格行中重复多少次.当发现3次或更多次时,我需要将td的颜色更改为红色,如下所示:

预期结果:

我的正则表达式正在工作,但我无法获得正确的重复计数并更改td的颜色....

x = $("table").find("tr");
text = "";

x.each(function(line){
  number = $(this).text();
  check = checkNum(number);
  console.log(checkNum(number));

  if(check.length > 0){
    repeats = check[0][1];
    text += "Number "+number[check[0]['index']]+" was repeated "+repeats+ " times on line "+line+"<br>";
    $('#results').html(text);
    $(this).css('color', 'red');
  }
});

function checkNum(num) {
    var tempArray = [];
    num = num.replace(/\s+/g,"_");
    exp = new RegExp(/([0-9])\1{2,}/, "g");
    ex = exp.exec(num);

    if(ex){
     tempArray.push(ex);
    }

    return tempArray;
}
