Jquery file tree - folder open by default?

Question

I was wondering if anyone can help me with the jQuery file tree ( jQuery file tree )

I was wondering if / how it would be possible to set some kind of variable that would tell the file tree to open a specific folder at boot time. (e.g. folder / images / fruit / will be opened by default)

Here is the code to call filetree:

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

And here is the filetree.js file:

// 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)

                                showTree( $(this).parent(), escape($(this).attr('rel').match( /.*\// )) );
                                $(this).parent().removeClass('collapsed').addClass('expanded');
                            } else {

                        } else {

                        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; });
                }

                $(this).html('<ul class="jqueryFileTree start"><li class="wait">' + o.loadMessage + '<li></ul>');
                // Get the initial file list
                showTree( $(this), escape(o.root) );
            });
        }
    });

})(jQuery);

Every time I tried to get along with him, I keep killing him since my javascript is not so good. Any help would be appreciated! :)

jqueryFileTree.js :

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

, filetree, :

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

jquery bindTree(c); showTree (c, t) 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');
       }
    });
}

Bermo awesome hack, ( , ) , :

jqueryFileTree.js

47, if (o.loadMessage == undefined) o.loadMessage = '...';:

if(o.expanded == undefined) o.expanded = '';

58 bindTree (c);:

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

:

:

var expansion_completed = false;

if bindTree() :

if (o.expanded != false) {
    $(c).find(".directory.collapsed").each(function (idx, li) {
        var rel = $(li).children().attr('rel');
        if (!expansion_completed && o.expanded.substr(0, rel.length) == rel) {
            showTree(li, rel);
            $(li).removeClass('collapsed').addClass('expanded');
        }
        if (o.expanded == rel) {
            expansion_completed = true;
            $(li).children("a").css('background-color', '#6080e0').css('color', 'white').css('font-weight', 'bold');
        }
    });
}

There are several advantages:

• Firstly, it does not use regular expressions, so it should be faster and less error prone.
• It remembers when it completed the extension, and will not re-expand everything if you close the parent and then re-expand it.
• It highlights the currently selected folder.

Answer 5

Just click on the click event.
