检查是否在特定div中填充了任何字段

Question

I have 10 div tags in my form, in each div there are 5 select boxes. For example we take first div which contains 5 select boxes, here I want to check whether any 1 of the 5 select boxes is selected or not.

If any one selected I need to display some links in my page, if nothing is selected I need to hide the links.

Thanks.

Using:

// Detect if a <select> has a value other than 0
function isSelected(){
    $('select').each(function(){
        if($(this).val() != '0'){
            return true;
        }
    });

    return false;
}

// Usage
if(isSelected()){
    // Do something
}
