通过javascript启用/禁用asp.net复选框

Enabling/disabling asp.net checkboxes through javascript

本文关键字：asp net 复选框 禁用 javascript 启用 通过      更新时间：2023-09-26

通过javascript启用和禁用复选框，例如当我检查chk1然后chk2, chk3和chk4将被启用，如果我取消检查chk1然后chk2, chk3和chk4将通过javascript禁用?

这是我的代码:

<script type="text/javascript">
$('chkTAR').clicked(function(){
        {
        if($('chkTAR :checked').length == 2)
        $('chkOasis, chkPOT').disabled = true;
        else
        $('chkOasis, chkPOT').disabled = false
        });
</script>

你可以试试:

   <script language="javascript" type="text/javascript">
       function oncheckchange(checked) { 
           var chk2 = document.getElementById('chk2'); 
           chk2.disabled = checked;  
       }
   </script>
  <asp:CheckBox OnClick="oncheckchange(this.checked);"  ID="chk1" runat="server" />
  <asp:CheckBox ID="chk2" runat="server" ClientIDMode="Static" />

注意chk2的ClientIDMode被设置为"Static"

这可能会帮助您禁用/启用复选框
