Test if element exists jquery -


I am trying to see if any of these is present in uls. I tested it. Length but I'm not sure I'm doing this right. This is alerts, even if there is no one with the selected sub-domain class. 

  if ($ ('ul.expul & gt; li.select-sub-domain'). Length & lt; 0) {var sub_doma = "set is not" ; Warning ("no"); } And {warnings ("yes"); Var all_domain = $ ('li.select-sub-domain'). Attr ('id'); Var sub_domainSplit = sub_domain.split ('-'); Var all_dom = all_domain split [1]; } & Lt; Ul class = "one expo" & gt; & Lt; Li class = 'select' id = eng-88> 1 & lt; / Li & gt; & Lt; Li class = 'Select' id = IN-89 & gt; 2 & lt; / Li & gt; & Lt; Li class = 'Select' id = eng-90 & gt; 3 & lt; / Li & gt; & Lt; Li class = 'Select' id = ins-91 & gt; 4 & lt; / Li & gt; & Lt; Li class = 'select' id = eng-92 & 5; 5 & ​​lt; / Li & gt; & Lt; Li class = 'select' id = eng-93 & gt; 6 & lt; / Li & gt; & Lt; Li class = 'selection' id = ing-94 & gt; 7 & lt; / Li & gt; & Lt; Li class = 'selection' id = ing-95 & gt; 8 & lt; / Li & gt; & Lt; Li class = 'select' id = ing-96 & gt; 9 & lt; / Li & gt; & Lt; Li class = 'selection' id = IN-97 & gt; 10 & lt; / Li & gt; & Lt; Li class = 'select' id = ins-98 & gt; 11 & lt; / Li & gt; & Lt; Li class = 'select' id = eng-99 & gt; 12 & lt; / Li & gt; & Lt; / Ul & gt; & Lt; Ul class = "hide two exposures" & gt; & Lt; Li class = 'select' id = wing-100 & gt; 1 & lt; / Li & gt; & Lt; Li class = 'Select' id = wing-0101 & gt; 2 & lt; / Li & gt; & Lt; Li class = 'select' id = fin-102 * 3 & lt; / Li & gt; & Lt; Li class = 'select' id = fin-104> 4 & lt; / Li & gt; & Lt; Li class = 'select' id = fin-104 * 5 & ​​lt; / Li & gt; & Lt; Li class = 'select' id = fin -100 & gt; 6 & lt; / Li & gt; & Lt; Li class = 'select' id = wing-102 & gt; 7 & lt; / Li & gt; & Lt; Li class = 'select' id = wing-107 & gt; 8 & lt; / Li & gt; & Lt; / Ul & gt; & Lt; Ul class = "hide three exposures" & gt; & Lt; Li class = 'selection' id = three-108 & gt; 1 & lt; / Li & gt; & Lt; Li class = 'selection' id = three-109 & gt; 2 & lt; / Li & gt; & Lt; Li class = 'selection' id = three -1010; 3 & lt; / Li & gt; & Lt; Li class = 'selection' id = three111 & gt; 4 & lt; / Li & gt; & Lt; Li class = 'selection' id = three112 & gt; 5 & ​​lt; / Li & gt; & Lt; Li class = 'select' id = three-113 & gt; 6 & lt; / Li & gt; & Lt; / Ul & gt;

change $ ('ul.expul & gt; Li.select -sub-domain '). Length & gt; 0)

to $ ('ul.expul & gt; li.select-sub-domain'). Length == 0)

You are the code like length greater than 0, warning number Which is not right.

This should not be shown when the length is equal to 0.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
