js 控制textbox的顯示與隱藏

aspx：      (如果radiobutton 為同1 group的，最好寫2個js函數 分別判斷每個的點擊)

 

             <asp:Radiobutton   id="radiobutton1" runat="server" />

 

             <asp:Radiobutton   id="  radiobutton2" runat="server" />

              <asp:Textbox  id="text" runat="server" />

 

js:

 

 

  function visible1() {
      
        var d = document.getElementById("rbLocked");                       //rblocked,rbpredefined 為同一group 的的 radiobutton  id
        var b = document.getElementById("rbPredefined");
        var e = document.getElementById("locktextbox");
//        alert(document.getElementById("locktextbox"));
//        alert(document.getElementById("txtInventory"));                 //變數大小寫

        if (d.checked == true && b.checked==false) {

            document.getElementById("locktextbox").disabled="" // = "visible";  lblock
            document.getElementById("lblock").disabled = "";
           
            document.getElementById("txtInventory").disabled = "disabled";
            document.getElementById("txtInventory").value = "";
//            document.getElementById("txtInventory").style.visibility = "hidden";
//           alert(e.style.visibility);
        }

    }
    function visible2() {

        var d = document.getElementById("rbLocked");                     
        var b = document.getElementById("rbPredefined");
        var e = document.getElementById("locktextbox");
        
        if ( b.checked ) {

            document.getElementById("locktextbox").disabled="disabled"; // = "visible";
            document.getElementById("lblock").disabled = "disabled";
            document.getElementById("txtInventory").disabled = "";
            document.getElementById("locktextbox").value = "";
//            document.getElementById("txtInventory").style.visibility = "visible";
//            alert(e.style.visibility);
        }

    }

 

C#:

           後台添加radiobutton的onclick屬性               

 

           rbLocked.Attributes.Add("onclick", "visible1()");
        rbPredefined.Attributes.Add("onclick", "visible2()");
