The Enter key should only be activated once the password has been entered into the designated password

Question

The Enter key should only be activated once the password has been entered into the designated password

I am facing an issue with 2 ASP textboxes for Login and Password. I want to automate the process so that when I enter the password and press enter, it should click the login button. I have tried several approaches found on Google, such as placing them all in a panel, but none seem to work. Can someone provide assistance with this problem?

Thank you.

Password.Attributes.Add("onkeydown", "if(event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('" + LoginRequest.UniqueID + "').click();return false;}} else {return true}; ");

javascript c#asp.net

Here is the solution that worked for me:

The first part should be added in the page load event:

txt_search.Attributes.Add("onkeypress", "changeFocus('btn_search')")

The second part should be placed in the header section of your ASP page or wherever you include your scripts:

<script language="javascript" type="text/javascript">
    function changeFocus(destinationBox) 
    {
      var key = window.event.keyCode;              
      if (key == 13)  
        document.getElementById(destinationBox).focus();
    } </script>

Simply replace btn_search with the ID of your button and txt_search with the ID of your password textbox.

If you simply add an element like the following to your form:

<button type="submit">Login</button>

The browser will likely handle it for you. It's a good idea to first check the HTML structure before diving into JavaScript. Although I'm not an expert in ASP, I have come across some unconventional form setups in similar web frameworks.

But if you do need to utilize JavaScript, here's a suggestion:

Password.Attributes.Add("onkeydown", 
    "if(event.which && event.which == 13 || event.keyCode && event.keyCode == 13){
        document.getElementById(
           '" + LoginRequest.UniqueID + "'
        ).click();
     return true;
    "
);

Chances are, your input field won't create a new line in the content, so there's no need to include a 'return false' statement.
