How to compare if string has a enter key in the end using jquery/javascript?
<p>I have a string value from a user input box. I have to figure out if last char is a enter key (line feed).</p>

<p>Thats the code. Here I am checking if last char has a whitespace. Now I also have to check if last char is enter key (carriage return or line feed). How can i do this?</p>

<pre><code>var txt = $get("&lt;%= txtUserText.ClientID %&gt;");
if (txt.value.substring(txt.value.length -1) !== ' ' || &lt;checkifLastCharIsEnterKey&gt;) 
  //my code to take action
</code></pre>

<p>*<strong>*I don't think i need a keypress or keyup event because this above piece of code is not invoked at the time of user input.</strong></p>
