텍스트로 요소 찾기

ID 나 클래스가 아닌 내용을 기반으로 요소를 찾을 수 있는지 누구든지 말할 수 있습니까 ?

고유 한 클래스 나 ID가없는 요소를 찾으려고합니다. (그런 다음 해당 요소의 부모를 찾아야합니다.)

Therefore it is not enough that you use :contains() selector, you also need to check if the text you search for is the direct content of the element you are targeting for, something like that:

따라서 :contains() selector 를 사용하는 것으로는 충분하지 않습니다. 검색하는 텍스트 가 대상 요소 의 직접 콘텐츠 인지 확인해야 합니다.

 Element에 포함된 텍스트(Text)로 객체를 찾아라!

function findElementByText(text) {
    var jSpot = $("b:contains(" + text + ")")
                .filter(function() { return $(this).children().length === 0;})
                .parent();  // because you asked the parent of that element

    return jSpot;
}

 * 아래 DIV   p-1 class 중에 텍스트가 3인 것을 찾아라. 

<div class="" id="pagenation" style="white-space: nowrap; overflow-x: hidden; width: 231px;">
<div class="p-1 paging-item border rounded text-center d-inline-block position-relative" style="width:33px;height:33px;">1</div>
<div class="p-1 paging-item border rounded text-center d-inline-block position-relative" style="width:33px;height:33px;">2</div>
<div class="p-1 paging-item border rounded text-center d-inline-block position-relative  style="width:33px;height:33px;">3</div>
<div class="p-1 paging-item border rounded text-center d-inline-block position-relative" style="width:33px;height:33px;">4</div>
<div class="p-1 paging-item border rounded text-center d-inline-block position-relative" style="width:33px;height:33px;">5</div><div class="p-1 paging-item border rounded text-center d-inline-block position-relative" style="width:33px;height:33px;">6</div><div class="p-1 paging-item border rounded text-center d-inline-block position-relative" style="width:33px;height:33px;">7</div>
</div>


$(".p-1:contains('3')")

jQuery 데이터 속성 값을 기반으로 요소를 찾는 방법은 무엇입니까?

jQuery how to find an element based on a data-attribute value?

I've got the following scenario:

var el = 'li';

and there are 5 <li>'s on the page each with a data-slide=number attribute (number being 1,2,3,4,5 respectively).

I now need to find the currently active slide number which is mapped to var current = $('ul').data(current); and is updated on each slide change.

So far my tries have been unsuccessful, trying to construct the selector that would match the current slide:

$('ul').find(el+[data-slide=+current+]);

does not match/return anything…

The reason I can't hardcode the li part is that this is a user accessible variable that can be changed to a different element if required, so it may not always be an li.

How to format $.now() with Jquery

$.now() gives me the time as miliseconds. I need to show it something like hh:mm:ss

$ .now ()는 시간을 밀리 초 단위로 제공합니다. hh : mm : ss와 같이 표시해야합니다.

How to format $.now() with Jquery

function formatTimeOfDay(millisSinceEpoch) {
  var secondsSinceEpoch = (millisSinceEpoch / 1000) | 0;
  var secondsInDay = ((secondsSinceEpoch % 86400) + 86400) % 86400;
  var seconds = secondsInDay % 60;
  var minutes = ((secondsInDay / 60) | 0) % 60;
  var hours = (secondsInDay / 3600) | 0;
  return hours + (minutes < 10 ? ":0" : ":")
      + minutes + (seconds < 10 ? ":0" : ":")
      + seconds;
}
