You want to trim the white space in case your users only enter a space, but you can check the length and the n set the value. Something along these lines should work.<br />
<br />
var inp = $(&quot;#txt&quot;).val();<br />
if(jQuery.trim(inp).length<wbr /> &lt;= 0)<br />
{<br />
&nbsp; &nbsp;$(&quot;#txt&quot;).val() = 0<br />
}<br />
<br />

if(jQuery.trim(inp).length <= 0)
{
   $("#txt").val() = 0

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.
