如何使按钮只能单击一次

Question

I AM Microsoft Visual Studio Basically I'm learning ASP and I'm trying to make an OnButtonClick postback. But when ever I try to make it OnButtonClick = true; Return SendButton.visible = false

I need to make my SendButton_Click So that when someone clicks * send * the button becomes unclickable.

I've tried searching the web, Our IT Guy said to google it but I just can't find what I need.

If someone can help.

I've attempted to use the following code, With no Succession.

<script type="text/javascript">
var wasSubmitted = false;
function checkBeforeSubmit() {
    if (!wasSubmitted) {
        wasSubmitted = true;
        return wasSubmitted;
    }
    return false;
}
</script>
<form onsubmit="return checkBeforeSubmit()" /> 
<asp:Button ID="SendButton" runat="server" Text="Send" OnClick="SendButton_Click OnClientClick="Disable" />    

I want to make it so after the person has CLICKED: Send - They cannot click it multiple times there for sending the request multiple times.

As you're using WebForms have a look at PostBack Ritalin - it will do what you require very easily.

Or:

OnClientClick="if (!Page_ClientValidate()){ return false; } this.disabled = true; this.value = 'Please wait...';" 
UseSubmitBehavior="false"

This ensures the button isn't disabled when there are validation errors.
