jquery: i have to use parseInt() even when deal with numbers, why?
- by Syom
i have the following script
<select id="select1">
<option value="1">1day</option>
<option value="2">2day</option>
<option value="3">3day</option>
</select>
<select id="select2">
<option value="1">1day</option>
<option value="2">2day</option>
<option value="3">3day</option>
</select>
and jquery
$("#select2").change(function() {
var max_value = parseInt($("#select2 :selected").val());
var min_value = parseInt($("#select1 :selected").val());
if(max_value < min_value)
{
$("#select1").val($(this).val());
}
});
and now, what i can't understand anyway - if values of option elements are integer numbers, why i have to use parseInt()? in some cases it doesn't work without parseInt().
Thanks
