Bo'sh jQuery akkordeon panellarini qanday boshqarish mumkin? Akkordeon sarlavhasini bosishni qanday o'chirish mumkin?

Men Accordionn jQuery boshqaruvlaridan foydalanmoqdaman, quyida URL manzilini topishingiz mumkin:

Akkordeon: http://jqueryui.com/accordion/

Muammo: Qanday qilib bo'sh menyularni bosish mumkin emasligini boshqarishimiz mumkin; misol - Agar menda "2-bo'lim" menyusida biron bir element bo'lmasa, uni bosish mumkin emas. Buni qilganimda, u keyingi asosiy menyu elementini oldingisiga o'zgartiradi va buziladi yoki faqat bo'sh <div> qo'ysam, bosish o'rniga bo'sh menyu ochiladi. Kimdir yordam bera oladimi?

Agar sizda menyuda hech narsa bo'lmasa, nega uni bo'sh div ichiga joylashtirish bilan bezovta qilyapsiz?   -  person Jay Mayu    schedule 01.04.2013

Siz http://api.jqueryui.com/accordion/#event-beforeActivate bilan urinib ko'rishingiz mumkin. a>

$( ".selector" ).on( "accordionbeforeactivate", function( event, ui ) {} );

Funktsiyada siz ui.newPanel ni sinab ko'rishingiz mumkin, agar bo'sh bo'lsa, ushbu panelni faollashtirishni bekor qiling.

Men jsfiddle misolini yaratdim: http://jsfiddle.net/npthU/1/

    $( "#accordion" ).on( "accordionbeforeactivate", function( event, ui ) {

       if($.trim($( ui.newPanel ).html()).length == 0)
          event.preventDefault();

    });

Bo'sh divga ega bo'lgan maxsus panelni ochishni o'chirish uchun event.preventDefault(); ishlatiladi.

Kechirasiz, @freshbm, ehtimol sizning javobingiz ham to'g'ri edi, lekin afsuski, men tuzata olmayman. Ishonchim komilki, men tushunmaganman, lekin qandaydir tarzda men shunday qildim, iltimos, jsfiddle.net/wru3jni tekshiring. a> Baribir rahmat... - person mknayab; 01.04.2013

Mana ushbu kodning yangilanishi:

$('#'+_id).on( "accordionbeforeactivate", function( event, ui ) {
        if((($.trim($(ui.newPanel).html()).length == 0)&&($(ui.oldHeader).length==0))||(($.trim($(ui.newPanel).html()).length == 0)&&($(ui.newHeader).length))){event.preventDefault();});

Endi u yig'ish/yechishga imkon beradi
