使用外部锚链接打开特定的手风琴面板 [英] Open a specific accordion panel with an external anchor link

问题描述

我有一个自举式手风琴，并且工作正常.

I have a bootstrap accordion setup and working fine.

我需要在外部页面上具有链接，这些链接将:

I need to have links on external pages which will:

A)带您进入手风琴内的指定面板

A) Take you to the specified panel within the accordion

B)打开指定的面板

链接结构必须采用这种格式(示例):

The link structure needs to be in this format (example):

Page.html#collapseTwo
(当然，"collapseTwo"会发生变化，具体取决于面板)

Page.html#collapseTwo
(the 'collapseTwo' will change, of course, depending on the panel)

    $.expr[':'].containsCaseInsensitive = function(n, i, m) {
        return jQuery(n).text().toUpperCase().indexOf(m[3].toUpperCase()) >= 0;
    };

    $('#accordion_search_bar').on('change keyup paste click', function() {
        searchTerm = $(this).val();
        $('#accordion > .panel').each(function() {
            panelContainerId = '#' + $(this).attr('id');
            $(panelContainerId + ':not(:containsCaseInsensitive(' + searchTerm + '))').hide();
            $(panelContainerId + ':containsCaseInsensitive(' + searchTerm + ')').show();
        });
    });
}());

推荐答案

您可以使用 url参数进行操作.

(function() {
    var searchTerm, panelContainerId;
    // Create a new contains that is case insensitive
    $.expr[':'].containsCaseInsensitive = function(n, i, m) {
        return jQuery(n).text().toUpperCase().indexOf(m[3].toUpperCase()) >= 0;
    };

    $('#accordion_search_bar').on('change keyup paste click', function() {
        searchTerm = $(this).val();
        $('#accordion > .panel').each(function() {
            panelContainerId = '#' + $(this).attr('id');
            $(panelContainerId + ':not(:containsCaseInsensitive(' + searchTerm + '))').hide();
            $(panelContainerId + ':containsCaseInsensitive(' + searchTerm + ')').show();
        });
    });
  
  /* Function to get url parameter based on param name */
  function getUrlParameter(key) {
    key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
    var regex = new RegExp("[\\?&]" + key + "=([^&#]*)");
    var results = regex.exec(window.location.href);
    if (results == null)
      return "";
    else
      return unescape(results[1]).replace(/<script.*>.*<\/script>/g, "");
  }
  
  var panelId = getUrlParameter('panel');
  if(panelId){
    var $panel = $('#'+panelId);
    $panel.addClass('in');

    $('html,body').animate({
       scrollTop: $panel.offset().top},
    'slow');
  }
  
}());
