You need to first check to see if the check box or radio button is checked
or empty before you do anything else in your code.
Yes I am doing that while posting data. But I don't know ho to validate / check Ajax Data variable for empty before posting.
Like:
Code:
function clr(){
[color=#333333][font=monospace] // alert(url);[/font][/color]
[color=#333333][font=monospace] $("input:checkbox[name=color]:checked").each(function() {[/font][/color]
[color=#333333][font=monospace] selected.push($(this).val());[/font][/color]
[color=#333333][font=monospace] //console.log(selected);[/font][/color]
[color=#333333][font=monospace] });[/font][/color]
[color=#333333][font=monospace] // Sizes [/font][/color]
[color=#333333][font=monospace] $("input:checkbox[name=size]:checked").each(function() {[/font][/color]
[color=#333333][font=monospace] size.push($(this).val());[/font][/color]
[color=#333333][font=monospace] //console.log(selected);[/font][/color]
[color=#333333][font=monospace] });[/font][/color]
[color=#333333][font=monospace] $.ajax({[/font][/color]
[color=#333333][font=monospace] url:url,[/font][/color]
[color=#333333][font=monospace] method:"post",[/font][/color]
[color=#333333][font=monospace] data:{'colors':selected,'sizes':size},[/font][/color]
[color=#333333][font=monospace] success:function(data)[/font][/color]
[color=#333333][font=monospace] {[/font][/color]
[color=#333333][font=monospace]// [/font][/color]
[color=#333333][font=monospace] //console.log(data);[/font][/color]
[color=#333333][font=monospace] $("#mdv").html(data);[/font][/color]
[color=#333333][font=monospace] [/font][/color]
[color=#333333][font=monospace] }[/font][/color]
[color=#333333][font=monospace] [/font][/color]
[color=#333333][font=monospace] });[/font][/color]
[color=#333333][font=monospace] [/font][/color]
[color=#333333][font=monospace] [/font][/color]
[color=#333333][font=monospace] [/font][/color]
}
but I don't know how to get / validate it, like
data.color.length<0 or data.color !=='' etc.
