i created expandable content using jquery on several divs unique ids. code working want trigger function top navigation using anchor. have tried several things nothing works. new jquery appreciated.

i trying invoke click() function on each anchor.

here jquery:

(function($) {     $(document).ready(function () {         var panelspeed = 500;          var totalpanels = 6;          var defaultopenpanel = 0;          var accordian = true;           var panelheight = new array();         var currentpanel = defaultopenpanel;     var iconheight = parseint($('.icon-close-open').css('height'));     var highlightopen = true;      //initialise collapsible panels     function panelinit() {             (var i=1; i<=totalpanels; i++) {                 panelheight[i] = parseint($('#cp-'+i).find('.expandable-panel-content').css('height'));                 $('#cp-'+i).find('.expandable-panel-content').css('margin-top', -panelheight[i]);                 if (defaultopenpanel == i) {                     $('#cp-'+i).find('.icon-close-open').css('background-position', '0px -'+iconheight+'px');                     $('#cp-'+i).find('.expandable-panel-content').css('margin-top', 0);                 }             }     }      $('.expandable-panel-heading').click(function() {         var obj = $(this).next();         var objid = parseint($(this).parent().attr('id').substr(3,2));         currentpanel = objid;         if (accordian == true) {             resetpanels();         }          if (parseint(obj.css('margin-top')) <= (panelheight[objid]*-1)) {             obj.clearqueue();             obj.stop();             obj.prev().find('.icon-close-open').css('background-position', '0px -'+iconheight+'px');             obj.animate({'margin-top':0}, panelspeed);             if (highlightopen == true) {                 $('#cp-'+currentpanel + ' .expandable-panel-heading').addclass('header-active');             }         } else {             obj.clearqueue();             obj.stop();             obj.prev().find('.icon-close-open').css('background-position', '0px 0px');             obj.animate({'margin-top':(panelheight[objid]*-1)}, panelspeed);             if (highlightopen == true) {                 $('#cp-'+currentpanel + ' .expandable-panel-heading').removeclass('header-active');             }         }     });      function resetpanels() {         (var i=1; i<=totalpanels; i++) {             if (currentpanel != i) {                 $('#cp-'+i).find('.icon-close-open').css('background-position', '0px 0px');                 $('#cp-'+i).find('.expandable-panel-content').animate({'margin-top':-panelheight[i]}, panelspeed);                 if (highlightopen == true) {                     $('#cp-'+i + ' .expandable-panel-heading').removeclass('header-active');                 }             }         }     }     //uncomment these lines if expandable panels not fixed width , need resize    $( window ).resize(function() {       panelinit();     });      $(window).load(function() {         panelinit();     }); //end load }); //end ready  })(jquery);

the html expandable jquery content is:

<div class="expandable-panel" id="cp-3">     <div class="expandable-panel-heading">         <h2>testimonials<span class="icon-close-open"></span></h2>      </div>     <div class="expandable-panel-content">         <p>panel html...</p>     </div> </div>

the html anchors want trigger click() function are:

        <ul class="nav">             <a href="#cp-1" onclick="$( "a" ).trigger( "click" );"><li class="nav">what justice court judge?</li></a>             <a href="#cp-2"><li class="nav">about reeves jones</li></a>             <a href="#cp-3"><li class="nav">testimonials</li></a>             <a href="#cp-4"><li class="nav">polling locations</li></a>             <a href="#cp-5"><li class="nav">map</li></a>             <a href="#cp-6"><li class="nav">contact</li></a>         </ul>

thank in advance help!

if understand correctly, don't want trigger click event anchors, instead want trigger click event of corresponding navigation element when anchor clicked.

you can adding following code inside document-ready function:

$('.nav a').click(function() {     $($(this).attr('href')).find('.expandable-panel-heading').click(); });

this code registers click handler on <a> elements inside .nav element. uses href value of clicked <a> element jquery object representing navigation element.

in case, should not place "onclick" attribute on <a> elements.

btw: valid html, should nest <a> elements inside <li> elements, not other way around.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
