jquery文件树 - 默认情况下打开文件夹？

Question

我想知道是否有人可以帮我解决jQuery文件树(jQuery文件树)

我想知道是否/如何设置某种变量将告诉文件树在加载时打开某个文件夹.(例如,文件夹/ images/fruit /默认打开)

这是调用filetree的代码:

$('#container_id').fileTree({ 
  root: '/images/' 
}, function(file) {
  alert(file);
});

这是filetree.js文件:

// Usage: $('.fileTreeDemo').fileTree( options, callback )
//
// Options:  root           - root folder to display; default = /
//           script         - location of the serverside AJAX file to use; default = jqueryFileTree.php
//           folderEvent    - event to trigger expand/collapse; default = click
//           expandSpeed    - default = 500 (ms); use -1 for no animation
//           collapseSpeed  - default = 500 (ms); use -1 for no animation
//           expandEasing   - easing function to use on expand (optional)
//           collapseEasing - easing function to use on collapse (optional)
//           multiFolder    - whether or not to limit the browser to one subfolder at a time
//           loadMessage    - Message to display while initial tree loads (can be HTML)

if(jQuery) (function($){

    $.extend($.fn, {
        fileTree: function(o, h) {
            // Defaults
            if( !o ) var o = {};
            if( o.root == undefined ) o.root = '/';
            if( o.script == undefined ) o.script = 'jqueryFileTree.php';

            $(this).each( function() {

                    $(".jqueryFileTree.start").remove();
                    $.post(o.script, { dir: t }, function(data) {
                        $(c).find('.start').html('');
                        $(c).removeClass('wait').append(data);
                        if( o.root == t ) $(c).find('ul:hidden').show(); else $(c).find('ul:hidden').slideDown({ duration: o.expandSpeed, easing: o.expandEasing });
                        bindTree(c);
                    });
                }
                function bindTree(t) {
                    $(t).find('li a').bind(o.folderEvent, function() {
                        if( $(this).parent().hasClass('directory') ) {
                            if( $(this).parent().hasClass('collapsed') ) {
                                // Expand
                                if( !o.multiFolder ) {
                                    $(this).parent().parent().find('ul').slideUp({ duration: o.collapseSpeed, easing: o.collapseEasing });
                                    $(this).parent().parent().find('li.directory').removeClass('expanded').addClass('collapsed');
                                }
                                $(this).parent().find('ul').remove(); // cleanup
                                showTree( $(this).parent(), escape($(this).attr('rel').match( /.*\// )) );
                                $(this).parent().removeClass('collapsed').addClass('expanded');
                            } else {
                                // Collapse
                                $(this).parent().find('ul').slideUp({ duration: o.collapseSpeed, easing: o.collapseEasing });
                                $(this).parent().removeClass('expanded').addClass('collapsed');
                            }
                        } else {
                            h($(this).attr('rel'), $(this).attr('name'), $(this).attr('title'), $(this).attr('id'));
                        }
                        return false;
                    });
                    // Prevent a from triggering the # on non-click events
                    if( o.folderEvent.toLowerCase != 'click' ) $(t).find('li a').bind('click', function() { return false; });
                }
                // Loading message
                $(this).html('<ul class="jqueryFileTree start"><li class="wait">' + o.loadMessage + '<li></ul>');
                // Get the initial file list
                showTree( $(this), escape(o.root) );
            });
        }
    });

})(jQuery);

每当我试图搞砸它时,我一直在杀它,因为我的javascript不是很好.任何帮助,将不胜感激!:)

为jqueryFileTree.js添加一个额外的默认属性,以便扩展文件夹:

if (o.expandedFolders == undefined) o.expandedFolders = [];

更新代码以调用filetree以包含要扩展的默认文件夹:

$(document).ready(function () {
        $('#container_id').fileTree({ 
             root: '/', 
             expandedFolders: ['/images/','/images/fruit/'] 
            }, function (file) {
            alert(file);
        });
    });

然后将后直接添加以下jQuery代码bindTree(c);行到showTree(C,T)在功能jqueryFileTree.js:

if (o.expandedFolders != null) {
    $(c).find(".directory.collapsed").each(function (i,f) {
       if ($.inArray($(f).children().attr('rel'), $(o.expandedFolders)) != -1) {
           showTree($(f), escape($(f).children().attr('rel').match(/.*\//)));
           $(f).removeClass('collapsed').addClass('expanded');
       }
    });
}
