the code select check-boxes doesn't seem work , don't know why.

pd: put scripts in base layout way:

<script type="text/javascript" src="{{ url_for('static', filename='js/eh.js') }}"></script>

i think should clarify something, main checkbox not created dynamically. modified code:

{% block script %}     <script type="text/javascript" src="{{ url_for('static', filename='js/jquery.validate.min.js') }}"></script>      <script>     $(document).ready(function(){         $(document).on('change', '#checkall', function () {             $('.chk').on.prop('checked', this.checked);         });          $(document).on('change', '.chk', function () {             if ($(".chk:checked").length == $(".chk").length) {                 $('#checkall').prop('checked', 'checked');             } else {                 $('#checkall').prop('checked', false);             }         });         });     </script> {% endblock %}

since checkboxes being generated dynamically, notation, 

$("#checkall").change(function(){    ...

as of jquery 1.7 should jquery.fn.on

$(document).on('change', '#checkall', function() ...

there detailed article on here event binding on dynamically created elements?

which might explain why script not working.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
