代码:
<!DOCTYPE html> <html xmlns=\"http://www.w3.org/1999/xhtml\"> <head> <meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /> <title></title> <link href=\"js/themes/default/easyui.css\" rel=\"stylesheet\" /> <link href=\"js/themes/icon.css\" rel=\"stylesheet\" /> <script src=\"js/jquery-1.8.0.min.js\"></script> <script src=\"js/jquery.easyui.min.js\"></script> <script src=\"js/locale/easyui-lang-zh_CN.js\"></script> <script type=\"text/javascript\"> var data = [{ \"id\": 1, \"text\": \"系统\", \"children\": [{ \"id\": 11, \"text\": \"用户管理\", \"children\": [{ \"id\": 19, \"text\": \"增加\" }, { \"id\": 3, \"text\": \"修改\" }, { \"id\": 5, \"text\": \"删除\" }] }, { \"id\": 12, \"text\": \"角色管理\", \"children\": [{ \"id\": 13, \"text\": \"增加\" }, { \"id\": 3, \"text\": \"修改\" }, { \"id\": 5, \"text\": \"删除\" }] }] }, { \"id\": 2, \"text\": \"其他\", \"state\": \"closed\" }]; $(function () { $(\"#tt\").tree({ data: data, checkbox: true, cascadeCheck: false, onCheck: function (node, checked) { if (checked) { var parentNode = $(\"#tt\").tree(\'getParent\', node.target); if (parentNode != null) { $(\"#tt\").tree(\'check\', parentNode.target); } } else { var childNode = $(\"#tt\").tree(\'getChildren\', node.target); if (childNode.length > 0) { for (var i = 0; i < childNode.length; i++) { $(\"#tt\").tree(\'uncheck\', childNode[i].target); } } } } }); }); function getChecked() { var arr = []; var checkeds = $(\'#tt\').tree(\'getChecked\', \'checked\'); for (var i = 0; i < checkeds.length; i++) { arr.push(checkeds[i].id); } alert(arr.join(\',\')); } </script> </head> <body> <ul id=\"tt\"></ul> <input type=\"button\" value=\"获取选中\" onclick=\"getChecked()\" /> </body> </html>
