使用 Jquery 單擊時顯示 div 的問題

如果你運行我的代碼片段並開始點擊，你會看到像梅賽德斯、船或房子這樣的 div，這很好，但問題是當你第一次運行這個片段時，什麼都不會顯示，你需要點擊一些東西，這不是辦法去。 我怎樣才能讓第一個 div 從一開始就可見，然後你就可以隨意更改 div。 注意 我需要更改 div，因為在我的實際文件中有內容

$(".listOrderNavPC a").on("click",function(e) {
  e.preventDefault()
  $(".categoryInfoWrapper").hide();
  $("#"+$(this).find(".textOrderPC").text()).show().fadeIn(500);
})

.grid-container-order {
  display: grid;
  grid-template-columns: 0.4fr 1.1fr;
  grid-template-rows: 1fr;
  gap: 0px 0px;
  grid-template-areas: "leftOrderCol rightOrderCol";
  width: 60vw;
  margin-left: 20vw;
  margin-top: 5vh;
}

.leftOrderCol {
  grid-area: leftOrderCol;
}

.rightOrderCol {
  padding-top: 2vh;
  grid-area: rightOrderCol;
  border-left: 1px solid rgb(240, 240, 240);
}

.listOrderNavMobile {
  display: none;
}

.lineOrderPC {
  width: 90%;
  margin-left: 5%;
  height: 1px;
  background: rgb(238, 238, 238);
  margin-top: 1vh;
}

.listOrderWrapper {
  width: 100%;
  font-family: 'Montserrat', sans-serif;
}

.userWelcomeOrderPC {
  font-size: 18px;
  padding-bottom: 1vh;
  padding-left: 1vw;
}

.userNamePC {
  font-size: 20px;
  font-weight: 600;
  letter-spacing: -1px;
}

.linkOrderPC {
  position: relative;
  display: flex;
  width: 80%;
  align-items: center;
  font-size: 15px;
  line-height: 25px;
  padding: 12px 16px;
  color: rgb(0, 0, 0);
}

.linkOrderPC:hover {
  background: rgb(250, 250, 250);
  color: rgb(0, 0, 0);
}

.iconOrderPC {
  font-size: 22px;
  margin-right: 15px;
}



.categoryInfoWrapper { display: none; }

你可以使用 JavaScript 如另一個答案中所述，或者您可以使用 CSS 隱藏除第一個之外的所有內容。

.categoryInfoWrapper:not(:first-child) { display: none; }

$(".listOrderNavPC a").on("click",function(e) {
  e.preventDefault()
  $(".categoryInfoWrapper").hide();
  $("#"+$(this).find(".textOrderPC").text()).show().fadeIn(500);
})

.grid-container-order {
  display: grid;
  grid-template-columns: 0.4fr 1.1fr;
  grid-template-rows: 1fr;
  gap: 0px 0px;
  grid-template-areas: "leftOrderCol rightOrderCol";
  width: 60vw;
  margin-left: 20vw;
  margin-top: 5vh;
}

.leftOrderCol {
  grid-area: leftOrderCol;
}

.rightOrderCol {
  padding-top: 2vh;
  grid-area: rightOrderCol;
  border-left: 1px solid rgb(240, 240, 240);
}

.listOrderNavMobile {
  display: none;
}

.lineOrderPC {
