如何使用jQuery摺疊列表中的元素？

Question

我有以下列表：

<div class='sidebar-listview ui-listview' data-role='listview' data-theme='c'> 
     <li class='ui-li ui-li-static ui-body-c ui-li-has-icon io-sidebar-section io-sidebar-section-collapsed io-sidebar-section-advanced-toggle' id='0aa210f2-e811-4bae-aac0-649bf87fb240'> 
     <img src='/document/d5308dfc-af9e-41a4-ab0f-9b5ff6c4c43e/latest' class='ui-li-icon ui-li-thumb' height='16' width='16'/> 
     <div class='io-sidebar-link-text'>Activities</div> 
     </li> 
     <span io-sidebar-section='0aa210f2-e811-4bae-aac0-649bf87fb240'> 
     <li class='ui-li ui-li-static ui-body-d ui-li-has-icon io-sidebar-link io-sidebar-link-standard' data-theme='d' io-sidebar-section='0aa210f2-e811-4bae-aac0-649bf87fb240' io-object-view='/cms?url=ui/object&object=34029fec-b949-3780-b9e6-9522413b9f2c' io-record-view='/cms?url=ui/record&object=34029fec-b949-3780-b9e6-9522413b9f2c' style='display: block'> 
      <img src='/document/140075b9-878e-4fc8-9ed6-ac422046accf/latest' class='ui-li-icon ui-li-thumb' height='16' width='16'/> 
      <div class='io-sidebar-link-text'>Events</div> 
     </li> 
     <li class='ui-li ui-li-static ui-body-d ui-li-has-icon io-sidebar-link io-sidebar-link-standard' data-theme='d' io-sidebar-section='0aa210f2-e811-4bae-aac0-649bf87fb240' io-object-view='/cms?url=ui/object&object=db13a9ad-2494-34bb-8a59-cb99fd308051' io-record-view='/cms?url=ui/record&object=db13a9ad-2494-34bb-8a59-cb99fd308051' style='display: block'>

      <div class='io-sidebar-link-text'>Tasks</div> 
     </li> 
     <li class='ui-li ui-li-static ui-body-d ui-li-has-icon io-sidebar-link io-sidebar-link-standard' data-theme='d' io-sidebar-section='0aa210f2-e811-4bae-aac0-649bf87fb240' io-object-view='/cms?url=ui/object&object=23505d2a-bf3b-11e0-8058-001ec93afa2c' io-record-view='/cms?url=ui/record&object=23505d2a-bf3b-11e0-8058-001ec93afa2c' style='display: block'>

      <div class='io-sidebar-link-text'>Projects</div> 
     </li> 
     <li class='ui-li ui-li-static ui-body-d ui-li-has-icon io-sidebar-link io-sidebar-link-advanced' data-theme='d' io-sidebar-section='0aa210f2-e811-4bae-aac0-649bf87fb240' io-object-view='/cms?url=ui/object&object=5e0d648c-bf52-11e0-b7e6-001ec93afa2c' io-record-view='/cms?url=ui/record&object=5e0d648c-bf52-11e0-b7e6-001ec93afa2c' style='display: none'> 
      <img src='/document/8dbc2454-a2f8-47b0-ba32-d5b8552c0160/latest' class='ui-li-icon ui-li-thumb' height='16' width='16'/> 
      <div class='io-sidebar-link-text'>Milestones</div> 
     </li> 
     </span> 

我如何能趕上io-sidebar-section-collapsed click事件，並在它的跨度崩潰它下面的一切嗎？

Answer 1

我認爲這應該工作：

var el = $('.io-sidebar-section-collapsed'); 
el.click(function() { 
    el.next().toggle(); 
}); 

如果你不想切換顯示和公正的崩潰，與.hide更換.toggle。

編輯：再次查看您的代碼，我不確定它是否會工作，因爲您的標記無效。您可以簡單地刪除跨度並將上面的代碼替換爲：

var el = $('.io-sidebar-section-collapsed'); 
el.click(function() { 
    el.next().toggle(); 
    el.next().next().toggle(); 
});
