The following replaces the first and third coughs, adding red.
var str = '測試文字測試文字測試文咳嗽字測試文字測試文字咳嗽測試文字測試文字測試文字測試文咳嗽字測試文字';
var result = str.replace(/(咳嗽)([^咳]+[^咳]+)/, '<span sytle="color:red"></span><span sytle="color:red"></span>');
console.log(result);
If you know the location, just subscript and add color. You can also use regular filtering
