javascript - Function has inconsistent return points -

when running intellij's inspections on javascript wrote, reports

function 'createpages' has inconsistent return points @ line 35

but i'm not sure means, or how solve issue.

the function looks this:

function createpages(noofcounts) {     var default_page = 1, default_count = 15;     if (noofcounts != "" && noofcounts != null) {         if (noofcounts > default_count) {             try {                 var tempval = parseint(noofcounts / default_count);                 jquery("#page").val(tempval);                 return true;             }             catch (e) {                 alert('error . ' + e);             }         } else {             alert("it should not less 15 , should number");             return false;         }     }     else {         jquery("#page").val(default_page);         return true;     } } 

and being called so:

var valid = createpages(noofcounts); 

your function (in effect) return undefined implicitly after reaches alert('error . ' + e);, because execution reach end of function without explicit return.

so making sure code paths through function return value explicitly rid of intellij error.
