jquery 文件树 - 文件夹默认打开? [英] jquery file tree - folder open by default?
问题描述
我想知道是否有人可以帮助我使用 jQuery 文件树(jQuery 文件树)
I was wondering if anyone could help me out with jQuery file tree (jQuery File Tree)
我想知道是否/如何设置某种变量来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)
I was wondering if/how it would be possible to set some kind of variable that will tell the file tree to have a certain folder open on load. (eg. folder /images/fruit/ to be open by default)
这是调用文件树的代码:
Here's the code to call the filetree:
$('#container_id').fileTree({
root: '/images/'
}, function(file) {
alert(file);
});
这里是 filetree.js 文件:
And here's 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)

if(jQuery) (function($){
$.extend($.fn, {

if( !o ) var o = {};
if( o.root == undefined ) o.root = '/';
if( o.script == undefined ) o.script = 'jqueryFileTree.php';
if( o.folderEvent == undefined ) o.folderEvent = 'click';

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);
每次我试图弄乱它时，我都会杀死它，因为我的 javascript 不是那么好.任何帮助，将不胜感激！:)
Every time I've tried to mess around with it, I keep killing it, as my javascript isn't that great. Any help would be appreciated! :)
推荐答案
为 jqueryFileTree.js 添加一个额外的默认属性，用于扩展文件夹:
Add an extra default property to jqueryFileTree.js for folders to expand:
if (o.expandedFolders == undefined) o.expandedFolders = [];
更新代码以调用文件树以包含要展开的默认文件夹:
Update the code to call the filetree to include the default folders to expand:
$(document).ready(function () {
$('#container_id').fileTree({
root: '/',
expandedFolders: ['/images/','/images/fruit/']
}, function (file) {
alert(file);
});
});
然后在bindTree(c);行后直接添加如下jquery代码到showTree(c, t)函数中<强>jqueryFileTree.js:
Then add the following jquery code directly after the bindTree(c); line to the showTree(c, t) function in 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');
}
});
}
