Question

在用户点击控制时,我已经做了一项守则,以排除控制。我的表格是TextBox和DropDown。当用户点击<代码>TextBox i将disable时,DropDown 如同在上点击时。 DropDown i 将可拆卸<代码>TextBox,该编码可操作。

但当用户点击<代码>可分解控制时,即希望能够进行这种控制。如在<条码>上点击残疾的电码>TextBox,则如<条码>所示。

My sample Script is as follows

<script type="text/javascript">

function toggleDropDownList1()
{
var d=document.getElementById("<%= DropDownList4.ClientID %>");
if(d.disabled)
{
d.disabled=false;
}
else
{
 document.getElementById("<%= TextBox1.ClientID %>").disabled = true;
}
}
function toggleDropDownList2()
{
 document.getElementById("<%= DropDownList4.ClientID %>").disabled = true;
}
</script>

Design

<asp:TextBox ID="TextBox1" runat="server" onclick="toggleDropDownList2();"></asp:TextBox>
        <asp:DropDownList ID="DropDownList4" runat="server" onclick="toggleDropDownList1();">
            <asp:ListItem Text="One" Value="1"></asp:ListItem>
            <asp:ListItem Text="One" Value="1"></asp:ListItem>
        </asp:DropDownList>

www.un.org/Depts/DGACM/index_spanish.htm 想法是把四分之四放在下级名单前面,这四分之三接受“低点”活动。

The issue here is that the div can not place so easy in front of dropdown list. To place it you need to do that dynamically and use the absolut position.

I make here a small code, and test it and working. I have left the background color RED on div to see where it is. Some details I left it to you, eg to find the width and height of your control list, I place the onclick, you can place back the double click, And just remove the red background.

<script type="text/javascript">
function toggleDropDownList1()
{
    var MyDiv = document.getElementById("DivForClick");
    MyDiv.style.display = "none";

    var d=document.getElementById("<%= DropDownList4.ClientID %>");
    if(d.disabled)
    {
        d.disabled=false;
    }
    else
    {
        document.getElementById("<%= TextBox1.ClientID %>").disabled = true;
    }
}

function toggleDropDownList2()
{
    document.getElementById("<%= DropDownList4.ClientID %>").disabled = true;

    var MyDdl = document.getElementById("<%= DropDownList4.ClientID %>");
    var MyDiv = document.getElementById("DivForClick");

    MyDiv.style.display = "block";
    MyDiv.style.left = MyDdl.style.left;
    MyDiv.style.top = MyDdl.style.top;

    // need to find the height/width
    // MyDiv.style.height = MyDdl.style.height;
    // MyDiv.style.width = MyDdl.style.width;   
}
</script>

和 as。

<asp:TextBox ID="TextBox1" runat="server" onclick="toggleDropDownList2();"></asp:TextBox>

<br /><br />

<div id="DivForClick" onclick="toggleDropDownList1();" style="z-index:999;position:absolute;left:0;top:0;height:20px;width:40px;background-color:Red;display:none;">
</div>

<asp:DropDownList ID="DropDownList4" runat="server" onclick="toggleDropDownList1();" style="z-index:2;">
   <asp:ListItem Text="One" Value="1"></asp:ListItem>
   <asp:ListItem Text="Two" Value="2"></asp:ListItem>
</asp:DropDownList>

表面上看,“......”和也许其他浏览器、残疾的电离层扰动在残疾的田地上的活动,以及从残疾场开始的任何活动都完全取消,不会传播多功能树。

So, if you want to achieve something like that, you will probably have to do it with a workaround.

不要实际上肢解外地,而是试图将田地划为残疾,这样你才能抓住点击事件。

Do you mean

function toggleIt() {
  var d=document.getElementById("<%= DropDownList4.ClientID %>");
  var t =document.getElementById("<%= TextBox1.ClientID %>");
  d.disabled=!d.disabled
  t.disabled=!t.disabled
}

<asp:TextBox ID="TextBox1" runat="server" onclick="toggleIt();"></asp:TextBox>
    <asp:DropDownList ID="DropDownList4" runat="server" disabled="disabled" onclick="toggleIt();">
        <asp:ListItem Text="One" Value="1"></asp:ListItem>
        <asp:ListItem Text="One" Value="1"></asp:ListItem>
    </asp:DropDownList>
