最近一个项目 需要用到jstree 这个jquery插件,就研究了下,做目录树 菜单还是很强大的,下面对经常会用到几个用法做下说明。
1. 首先页面 引用 jquery.jstree
2. html :
<div id="cate_tree" class="jstree fl"> <ul> <li id="0" class="jstree-closed jstree-unchecked"> <a href="#" class="jstree-clicked"> <ins class="jstree-checkbox"> </ins> All Product </a> <ul style=""> {foreach $categories as $cat} <li id="{$cat.id}" class="jstree-closed jstree-unchecked"> <a href="#" class="jstree-clicked"> <ins class="jstree-checkbox"> </ins> {$cat.name} </a> {if $cat.sub|@count > 0} <ul style=""> {foreach $cat.sub as $subcat} <li id="{$subcat.id}" class="jstree-leaf jstree-unchecked"> <a href="#" class=""> <ins class="jstree-checkbox"> </ins> {$subcat.name} </a> </li> {/foreach} </ul> {/if} </li> {/foreach} </ul> </li> </ul> </div>
默认所有目录树打开不选中, 样式为
class="jstree-closed jstree-unchecked">
默认打开目录树,样式为
class="jstree-open jstree-unchecked">默认需要全选,样式尝试class="jstree-open jstree-checked">3. js 加载该目录树// 设置jstree 主题路径 $.jstree._themes = Www_URL_JS + 'jstree/themes/'; $("#cate_tree").jstree({ "plugins" : [ "themes", "html_data", "checkbox", "ui" ], "themes": { "theme": "classic", "dots": true, "icons": false } });
默认主题 是default,是文件夹样式,classic 是 + - 号的样式
4. 获取选中的值var cate_ids = []; $("#cate_tree .jstree-checked").each(function(){ var $this = $(this); cate_ids.push($this.attr("id")); });
5. 设置给定的值为选中状态var cate_js_tree = $("#cate_tree").jstree({ "plugins" : [ "themes", "html_data", "checkbox", "ui" ], "themes": { "theme": "classic", "dots": true, "icons": false } }); cate_js_tree.bind('loaded.jstree', function () { $("#cate_tree").find("li").each(function() { var $this = $(this); for(x in cate_ids) { if ($this.attr("id") == cate_ids[x]) { $("#cate_tree").jstree("check_node", $this); } } }); });
6. 如果还有不太明白的,可以访问官网查询,嘿嘿……附上这个地址,本人觉得很不错,哈哈http://www.jstree.com/documentation/checkbox
