关于改变情况的Jquery

Question

我有这段代码

from child import *

$('#sel_kat').change(function() { $("#" + this.value).show(); }); 在CSS中设置为#sel_kat。当我在display: none;代码中选择一些值时，会显示<select> div。当我选择其他值时，如何隐藏此div？

Answer 1

首先，在与Sub updt() Dim sh1 As Worksheet, sh2 As Worksheet, lr As Long, rng As Range Set sh1 = Sheets(1) 'Edit sheet name Set sh2 = Sheets(2) 'Edit sheet name lr = sh1.Cells(Rows.Count, 1).End(xlUp).Row Set rng = sh1.Range("A2:A" & lr) For Each c In rng If WorksheetFunction.CountIf(sh2.Range("A:A"), c.Value) = 0 Then sh2.Range("A" & sh2.Cells(Rows.Count, 1).End(xlUp).Row)(2) = c.Value End If Next End Sub 值相关的所有div元素上放置一个公共类。然后你可以在显示所选的一个之前隐藏它们：

select

Answer 2

或者您可以隐藏最后选择的项目

$('#sel_kat').change(function() {
    var lastSelect = $('#sel_kat:last').val();
    $("#" + lastSelect).hide();
    $("#" + this.value).show(); // show selected
});
