unzip and configure local nginx or simpleHTTPd

for nginx start working:

Code:

net start nginx
cd folderWithAPP
index.html

stop working:

Code:

net stop nginx

in one page I have two combobox:

Code:

  A: <input id="dgFilterA" class="easyui-combobox" style="width:200px" data-options="editable:false, onChange:dgFilterOnChange, url:'//ajx.$DOMAIN/?vg&s=sv&auth=$AJX_AUTH', method:'get', valueField:'ID', textField:'Name', groupField:'Owned', formatter: fmtComboFilterA, panelHeight:'auto', multiple:true, cls:'fltA'">

  B: <input id="dgFilterB" class="easyui-combobox" style="width:230px" data-options="editable:false, onChange:dgFilterOnChange, url:'//ajx.$DOMAIN/?vg&s=sl&auth=$AJX_AUTH', method:'get', valueField:'ID', textField:'Name', groupField:'Group', formatter: fmtComboFilterB, panelHeight:'auto', multiple:true, cls:'fltB'">

for filter B I dont need Name of group, so I`m in my css file do:

Code:

.combobox-group {
    /* display: none; */
    border-top: 1px solid silver;
    font-size: 0;
    padding: 0;
}

but this code hide GroupCaption and for FilterA

cls property is set value of class only to
  <span class="textbox combo" ...
and  not to
  <div class="panel combo-p panel-htop" .....

How I do it?

in html:

Code:

 <input id="iCheck" 
    class="easyui-switchbutton"
    data-options="onChange:iCheckChange"
 >
 <input id="iCombo"
    class="easyui-combobox"
    data-options="mode:'remote'
                , disabled: true
                , required: false
                , loader: ...
                "
  >

in script

Code:

function iCheckChange(aChecked){
  $('#iCombo').combobox(aChecked?'enable':'disable').combobox('options').required = aChecked;
};
