Javascript无法禁用asp.NET linkBut​​ton

Question

我查看了网络和我的代码，但我无法找到问题。请帮忙。我的代码如下。我创建了一些链接按钮，它们调用回发到后端，触发javascript来禁用/启用链接按钮。不幸的是，我无法这样做。它甚至可以通过javascript完成吗？知道为什么吗？

请帮忙......谢谢

<ul class="nav nav-tabs">
      <li role="presentation" class="active" ID="tab1"><asp:LinkButton ID="tab1Link" runat="server"><strong>Basic</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab2"><asp:LinkButton ID="tab2Link" runat="server"><strong>Details+</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab3"><asp:LinkButton ID="tab3Link" runat="server"><strong>Location</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab4"><asp:LinkButton ID="tab4Link" runat="server"><strong>Media</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab5"><asp:LinkButton ID="tab5Link" runat="server" OnClientClick="javascript: tabSeq('tab5', 5)"><strong>Summary</strong></asp:LinkButton></li>
    </ul>




function tabSeq(activeTab, numberOfTabs) 
{
var tabOKVal = "";
for (var i = 1; i <= numberOfTabs; i++)
{
    document.getElementById('tab'+ i).className = "";
    document.getElementById('tab'+ i+"Div").style.display = 'none';

    tabOKVal = document.getElementById('tabOK'+ i).value;
    if(tabOKVal == "OK" && i != numberOfTabs)
    {
        document.getElementById('tab' + (i+1) + 'Link').disabled = "";
        document.getElementById('tab' + (i+1) + 'Link').style.color = '#3498DB';
    }
}
document.getElementById('tab5Link').disabled = "disabled";
document.getElementById(activeTab).style.color = '#555555';
document.getElementById(activeTab).className = "active";
document.getElementById(activeTab+"Div").style.display = '';
}

onload = function(){
   tabSeq('tab5', 5)
}

function tabSeq(activeTab, numberOfTabs) 
{
//other stuff goes here
document.getElementById('tab5Link').disabled = true;
document.getElementById(activeTab).style.color = '#555555';
document.getElementById(activeTab).className = "active";
document.getElementById(activeTab+"Div").style.display = '';
}

<ul class="nav nav-tabs">
      <li role="presentation" class="active" ID="tab1"><asp:LinkButton ID="tab1Link" runat="server"><strong>Basic</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab2"><asp:LinkButton ID="tab2Link" runat="server"><strong>Details+</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab3"><asp:LinkButton ID="tab3Link" runat="server"><strong>Location</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab4"><asp:LinkButton ID="tab4Link" runat="server"><strong>Media</strong></asp:LinkButton></li>
      <li role="presentation" ID="tab5"><button ID="tab5Link" runat="server" OnClientClick="javascript: tabSeq('tab5', 5)"><strong>Summary</strong></button></li>
    </ul>

LinkBut​​tons是ASP.NET服务器控件，您在设计时看不到控件ID值。

您可以按如下方式重写js代码：

document.getElementById("<%= tab5Link.ClientID %>").disabled = "disabled";

请注意，只有JS代码在同一页面上才能完成。
