javascript - Get asp.net RadioButtonList selected value with jQuery -

-

i want uncheck radiobuttonlist if click on listitem yet checked. code of radio:

<div class="filtrodiv100" style="margin-top: 17px;">                 <asp:radiobuttonlist id="rbttipi" runat="server" onclick="resetfun();" style="margin-top: 4px; margin-bottom: 8px;">                     <asp:listitem value="industriale">&nbsp; addizionale regionale industriale</asp:listitem>                     <asp:listitem value="civile">&nbsp; addizionale regionale civile</asp:listitem>                     <asp:listitem value="sostitutiva">&nbsp; addizionale regionale sostitutiva</asp:listitem>                     <asp:listitem value="imposta">&nbsp; imposta gas</asp:listitem>                 </asp:radiobuttonlist>             </div>

my function:

<script type="text/javascript" >     function resetfun() {         var radiobuttons = $('#<%=rbttipi.clientid%>');       var id= $(this).attr('value')         }     }  </script>

firstly, onclick attribute should onchange. because onchange captures change onclick fires after clicked , before change happens.

write resetfun() function below.

function resetfun() {     var radiobuttons = $('#<%=rbttipi.clientid%>');     var id = radiobuttons.find('input:checked').val(); // selected value }

alternative solution:

write onchange attribute onchange="resetfun(this);". pass radio button list element parameter javascript function.

and resetfun function below:

function resetfun(radio) {     alert($(radio).find('input:checked').val()); }

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
