单击后禁用asp.net按钮以防止双击

Question

I have an ASP.NET button that I need to disable after the user clicks it to prevent double-clicking. Once the submit completes it has to be enabled again. Can anyone help me with this?

Answer 1

Here is a solution that works for the asp.net button object. On the front end, add these attributes to your asp:Button definition:

<asp:Button ... OnClientClick="this.disabled=true;" UseSubmitBehavior="false" />

In the back end, in the click event handler method call, add this code to the end (preferably in a finally block)

myButton.Enabled = true;

Answer 2

I have found this , and it works:

btnSave.Attributes.Add(
    "onclick", 
    "this.disabled = true;" + ClientScript.GetPostBackEventReference(btnSave, null) + ";");

Answer 3

Check this link, the most simplest way and it does not disable the validations.

http://aspsnippets.com/Articles/Disable-Button-before-Page-PostBack-in-ASP.Net.aspx

If you have eg

  <form id="form1" runat="server">
      <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Clicked" />
  </form>

Then you can use

  <script type = "text/javascript">
  function DisableButton() {
      document.getElementById("<%=Button1.ClientID %>").disabled = true;
  }
  window.onbeforeunload = DisableButton;
  </script>

To disable the button if and after validation has succeeded, just as the page is doing a server postback.

Answer 4

If you want to prevent double clicking due to a slow responding server side code then this works fine:

<asp:Button ... OnClientClick="this.disabled=true;" UseSubmitBehavior="false" />

Try putting a Threading.Thread.Sleep(5000) on the _Click() event on the server and you will see the button is disabled for the time that the server is processing the click event.

No need for server side code to re-enable the button either!

Answer 5

<asp:Button ID="btnSend" runat="server" Text="Submit"  OnClick="Button_Click"/>

---

        <script type = "text/javascript">
            function DisableButton()
            {
                document.getElementById("<%=btnSend.ClientID %>").disabled = true;
            }
            window.onbeforeunload = DisableButton;
        </script>

Answer 6

If anyone cares I found this post initially, but I use ASP.NET's build in Validation on the page. The solutions work, but disable the button even if its been validated. You can use this following code in order to make it so it only disables the button if it passes page validation.

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Submit" OnClientClick=" if ( Page_ClientValidate() ) { this.value='Submitting..'; this.disabled=true; }" UseSubmitBehavior="false" />

Answer 7

Just need to add 2 attributes for asp button :

OnClientClick="this.disabled='true';"  UseSubmitBehavior="false"

eg

<asp:Button ID="Button1" runat="server" Text="TEST" OnClientClick="this.disabled='true';"  UseSubmitBehavior="false" CssClass="button-content btnwidth" OnClick="ServerSideMethod_Click"  />

Answer 8

您可以使用客户端onclick事件来执行此操作：

yourButton.Attributes.Add("onclick", "this.disabled=true;");

Answer 9

Disable the button on the OnClick event, then re-enable on the AJAX callback event handler. Here is how I do it with jQuery.

<script>
$(document).ready(function() {

    $('#buttonId').click(function() {
         $(this).attr('disabled', 'disabled');
         callAjax();
    });

});

function callAjax()
{
    $.ajax({
      url: 'ajax/test.html',
      success: function(data) {
         //enable button
         $('#buttonId').removeAttr('disabled');

      }
    });
}
</script>

Answer 10

using jQuery:

$('form').submit(function(){
    $(':submit', this).click(function() {
        return false;
    });
});

Answer 11

I like to disable the button and call a postback, this way the code behind still gets run after the button is disabled.

this is how i attach from code behind:

btnProcess.Attributes.Add("onclick", " this.disabled = true; __doPostBack('btnProcess', ''); return false;")

Then re-enable the button in code behind:

btnProcess.Enabled = True

Answer 12

Try this, it worked for me

<asp:Button ID="button" runat="server" CssClass="normalButton" 
Text="Button"  OnClick="Button_Click" ClientIDMode="Static" 
OnClientClick="this.disabled = true; setTimeout('enableButton()', 1500);" 
UseSubmitBehavior="False"/>  

Then

<script type="text/javascript">
function enableButton() {
document.getElementById('button').disabled = false;
}
</script>

You can adjust the delay time in "setTimeout"

Answer 13

This solution works if you are using asp.net validators:

<script language="javascript" type="text/javascript">
function disableButton(sender,group)
{
    Page_ClientValidate(group);
    if (Page_IsValid)
    {
        sender.disabled = "disabled";
        __doPostBack(sender.name, '');
    }
}</script>

and change the button:

<asp:Button runat="server" ID="btnSendMessage" Text="Send" OnClick="btnSendMessage_OnClick" OnClientClick="disableButton(this,'theValidationGroup')" CausesValidation="true" ValidationGroup="theValidationGroup" />

Answer 14

This works with a regular html button.

    <input id="Button1"
    onclick="this.disabled='true';" type="button"
    value="Submit" name="Button1"
    runat="server" onserverclick="Button1_Click">

The button is disabled until the postback is finished, preventing double clicking.

Answer 15

<script type = "text/javascript">
function DisableButtons() {
    var inputs = document.getElementsByTagName("INPUT");
    for (var i in inputs) {
        if (inputs[i].type == "button" || inputs[i].type == "submit") {
            inputs[i].disabled = true;
        }
    }
}
window.onbeforeunload = DisableButtons;
</script>

Answer 16

You can do this with javascript. in your form tag, onsubmit="javascript:this.getElementById("submitButton").disabled='true';"
