What if I want the result hidden and show only after selecting .

Answer 1

If I understand you want to show only result when typing or selecting in drop downs , So I've hided the p class at start then added some values to input ,

See below snippet :

 $("p").hide(); $('#filterDiv').on("change keyup", function() { $val0 = $('#0').val().trim(); $val1 = $('#1').val().trim(); $val2 = $('#2').val().trim(); if($val0 == "" && $val1 == "-" && $val2 =="-") { $("p").hide() return; } chkBox = { datatest: null }; if ($('#3').is(':checked')) { chkBox.datatest = "1"; } else { chkBox.datatest = ""; } $("p").hide().filter(function() { var rtnData = ""; regExName = new RegExp($val0, "ig"); regExA = new RegExp($val1 == "-" ? "" : $val1, "ig"); regExB = new RegExp($val2 == "-" ? "" : $val2, "ig"); regExTest = new RegExp(chkBox.datatest, "ig") rtnData = ( $(this).attr("data-name").match(regExName) && $(this).attr("data-a").match(regExA) && $(this).attr("data-b").match(regExB) && $(this).attr("data-test").match(regExTest) ); //console.log(rtnData); return rtnData; }).show(); });
