I'm using a jQuery with a OnClick event to show 3 dropdown menus. The problem is, when I go to another page and come back, the jQuery gets called twice, and stays called until I reload. This means that if I leave and enter again, the jQuery gets called 3 times now.

Is there anyway to prevent the jQuery to get called multiple times?

Edit: Forgot the code of the jQuery

 jQuery('body').on('click', '.headerDetalhe', function() {

           $headerDetalhe = jQuery(this);

           var ExpandableTitulo = this.getAttribute('data-Titulo');
           var ExpandableParent = this.getAttribute('data-Parent');
           var ExpandableCurrente = this.getAttribute('data-Currente');
           var ExpandableID = this.getAttribute('data-ExpandableID');
           var ExpandableICON = this.getAttribute('data-Icon')

           $contentDetalhe = $headerDetalhe.next();

           if(jQuery(this).hasClass('ActiveExpandable')) {
               if((ExpandableParent > 0) && (ExpandableCurrente > 0)){
                   jQuery(this).removeClass('ActiveExpandable');
                   jQuery(this).removeClass('FirstExpandable');
                   var ExpProd = document.querySelectorAll('[id^="ExpandableID"]');
                       ExpProd = [].slice.call(ExpProd);
                       ExpProd.forEach(function (elem) {
                           var Titulo = elem.dataset.titulo;
                           var Parent = elem.dataset.parent;
                           var Currente = elem.dataset.currente;
                           var ExpID = elem.dataset.expandableid;
                           var Icon = elem.dataset.Icon;

                           /*if((ExpandableParent == Parent) && (Currente == 0)){
                               document.getElementById("IDExpContainer" + ExpID).style.display = "none";
                           }*/

                   });
                   $contentDetalhe.slideToggle(500, function () {
                       $headerDetalhe.html(function () {
                           return $contentDetalhe.is(":visible") ? "<span class='TextExpandableAtivo " + ExpandableICON + "' id='Text" + ExpandableID + "'> Comunicados de Imprensa <span class='SinalExpandableAtivo' id='IDSignal" + ExpandableID + "'>-</span></span>" : "<span class='TextExpandable " + ExpandableICON + "' id='Text" + ExpandableID + "'>" + ExpandableTitulo + "<span class='SinalExpandable' id='IDSignal" + ExpandableID + "'>+</span></span>";
                       });
                   });

               }
               else{
                   jQuery(this).removeClass('ActiveExpandable');

                   $contentDetalhe.slideToggle(500, function () {
                       $headerDetalhe.html(function () {
                           return $contentDetalhe.is(":visible") ?

                       });
                   });

               }
           }
           else{
               if((ExpandableParent > 0) && (ExpandableCurrente > 0)){
                   jQuery(this).addClass('ActiveExpandable');
                   var ExpProd = document.querySelectorAll('[id^="ExpandableID"]');
                       ExpProd = [].slice.call(ExpProd);
                       ExpProd.forEach(function (elem) {
                           var Titulo = elem.dataset.titulo;
                           var Parent = elem.dataset.parent;
                           var Currente = elem.dataset.currente;
                           var ExpID = elem.dataset.expandableid;

                            if((ExpandableParent == Parent) && (Currente == 0)){
                               document.getElementById("IDExpContainer" + ExpID).style.display = "block";
                            }

                   });

                   $contentDetalhe.slideToggle(500, function () {
                       $headerDetalhe.html(function () {
                           return $contentDetalhe.is(":visible") ? "<span class='TextExpandableAtivo " + ExpandableICON + "' id='Text" + ExpandableID + "'>" + ExpandableTitulo + "<span class='SinalExpandableAtivo' id='IDSignal" + ExpandableID + "'>-</span></span>" : "<span class='TextExpandable " + ExpandableICON + "' id='Text" + ExpandableID + "'>" + ExpandableTitulo + "<span class='SinalExpandable' id='IDSignal" + ExpandableID + "'>+</span></span>";
                       });
                   });

               }
               else{
                   jQuery(this).addClass('ActiveExpandable');

                   $contentDetalhe.slideToggle(500, function () {
                       $headerDetalhe.html(function () {
                           return $contentDetalhe.is(":visible") ? "<span class='TextSubExpandableAtivo " + ExpandableICON + "' id='Text" + ExpandableID + "'>" + ExpandableTitulo + "<span class='SinalExpandableAtivo' id='IDSignal" + ExpandableID + "'>-</span></span>" : "<span class='TextSubExpandable " + ExpandableICON + "' id='Text" + ExpandableID + "'>" + ExpandableTitulo + "<span class='SinalExpandable' id='IDSignal" + ExpandableID + "'>+</span></span>";
                       });
                   });
               }
           }

       });

I think there are some confusions here, after leaving and enter, the dropdown after being clicked, it will open and then close (being called twice).

Thank you

    Can you please add the code you are using to your question? – Ganesh Sanap Oct 16 at 10:25

  • This doesn't work. I'm using 3 dropdown columns. Using 'one', just let me open one dropdown, and then doesn't let me open or close any of them, and that's not my problem. – João Oct 16 at 10:40
