Prevent a negative number in JS click counter
<p>I have a simple JS counter with two buttons (+ and -) that is used to tally people. Works fine, but it allows the user to go into the negative when decreasing the count. Probably a simple solution but not for me. Any help would be appreciated. Thanks.</p>

<p>JS</p>

<pre><code>    //Pax Counter

$(document).ready(function(){
    //Count Function
    $('#increase').click(function() {
    $('#pax_count').val(function(i, val) { return val*1+1 });
});
    $('#decrease').click(function() {
    $('#pax_count').val(function(i, val) { return val*1-1 });
}); 

  });
</code></pre>

<p>HTML</p>

<pre><code>&lt;input name="pax_count" type="text" class="pax_input_box" id="pax_count" value="0" &gt;

&lt;div id="pax_counter_container"&gt;&lt;!-- open #pax_counter_container --&gt;
&lt;button id="increase" type="button" class="click_button" onTouchStart="EvalSound('audio3')"&gt;&lt;/button&gt;
&lt;button id="decrease" type="button" class="click_button" onTouchStart="EvalSound('audio3')"&gt;&lt;/button&gt;
&lt;/div&gt;&lt;!-- close #pax_counter_container --&gt;
</code></pre>
