如果已经提出这个问题，请告诉我在哪里可以找到答案
我正在尝试创建一个表单，根据下拉菜单中的选择，它将显示不同的表行。我在使用JavaScript时已成功完成此操作，但我现在正尝试从JavaScript迁移到jQuery，并且我很难确定要使用的正确函数。
这是一个带有JavaScript编码的JSFiddle文件
var myVar = setInterval(myTimer, 1000);
function myTimer() {
var d = new Date();
var dd = d.getDay();
var day1;
var day2;
var d_d = d.getMonth();
switch (d_d) {
case 0:
day2 = "January";
break;
case 1:
day2 = "February";
break;
case 2:
day2 = "March";
break;
case 3:
day2 = "April";
break;
case 4:
day2 = "May";
break;
case 5:

break;
case 6:
day2 = "July";
break;
case 7:
day2 = "August";
break;
case 8:
day2 = "September";
break;
case 9:
day2 = "October";
break;
case 10:
day2 = "Novmber";

case 11:

case 6:

}
document.getElementById("day").value = day1;
document.getElementById("time").value = d.toLocaleTimeString();
document.getElementById("date").value = day2 + " " + d.getDate();
}

同样，jquery函数的目标应该是根据所选的“商店ID”隐藏/显示几个表行。
提前感谢您提供任何帮助
答案 0 :(得分：0)
这个jQuery版本：
document.getElementById("frig1").classList.add("hide");
是
$("#frig1").hide();
要显示元素，请使用
$("#frig1").show();
如果您想隐藏多个元素，可以使用：
$("#frig1, #frig2").hide();
