2. organize.js：实现界面按钮的功能
function viewModel() {

});
}
this.addClick = function () {

self.openDiloag("添加新机构", defaults, function (vm, win) {
if (com.formValidate(win)) {

self.save(vm,win);
}
});
};
this.editClick = function () {

this.organizeName = ko.observable(self.selectNode.organizeName);
com.loadCss(rootPath+'/content/css/metro/css/modern.css', parent.document);
com.ajax({
type: 'GET',
url: rootPath+'/sys/role!getRoleWithOrganizeCheck.do?organizeId=' + self.selectNode.id,
success: function (d) {
var ul = w.find(".listview");
for (var i in d)
ul.append(utils.formatString('<li role="{0}" class="{2}">{1}</li>', d[i].id, d[i].roleName, d[i].checked == 'true' ? 'selected' : ''));
ul.find("li").click(function () {

this.openDiloag = function (title,node,fnConfirm) {

}
3. organizeTreeGraph.js：实现结构树的绘制
function renderTreeGraph(treeData) {
//生成图形
var tb = $('<table class="tb-node" cellspacing="0" cellpadding="0" align="center" border="0" style="border-width:0px;border-collapse:collapse;margin:0 auto;vertical-align:top"></table>');
var tr = $('<tr></tr>');
for (var i in treeData) {
if (i > 0) $('<td> </td>').appendTo(tr);
$('<td style="vertical-align:top;text-align:center;"></td>').append(createChild(treeData[i])).appendTo(tr);
}
tr.appendTo(tb);
return tb;
}
//递归生成机构树图形
function createChild(node, ischild) {
var length = (node.children || []).length;
var colspan = length * 2 - 1;
if (length == 0)
colspan = 1;
var fnTrVert = function () {
var tr1 = $('<tr class="tr-vline"><td align="center" valign="top" colspan="' + colspan + '"><img class="img-v" src="'+rootPath+'/content/images/tree/Tree_Vert.gif" border="0"></td></tr>');
return tr1;
};
//1.创建容器
var tb = $('<table class="tb-node" cellspacing="0" cellpadding="0" align="center" border="0" style="border-width:0px;border-collapse:collapse;margin:0 auto;vertical-align:top"></table>');
//var tb = $('<table style="BORDER-BOTTOM: 1px solid; BORDER-LEFT: 1px solid; BORDER-TOP: 1px solid; BORDER-RIGHT: 1px solid" border="1" cellspacing="0" cellpadding="2" align="center"></table>');
//2.如果本节点是子节点，添加竖线在节点上面
if (ischild) {
fnTrVert().appendTo(tb);
}
// 3.添加本节点到图表
var tr3 = utils.functionComment(function () {/*
<tr class="tr-node"><td align="center" valign="top" colspan="{0}">
<table align="center" style="border:solid 2px" border="1" cellpadding="2" cellspacing="0">
<tr>
<td class="td-node" id='td{3}' data-node='{2}' align="center" valign="top" style="background-color:#f6f6ff;cursor:pointer;padding:2px;">{1}</td>
</tr>
</table>
</td></tr> */
});
tr3 = utils.formatString(tr3, colspan, node.organizeName, JSON.stringify(node),node.id);
$(tr3).appendTo(tb);
// 4.增加上下级的连接线
if (length > 1) {
//增加本级连接下级的首节点竖线，在节点下方
fnTrVert().appendTo(tb);
//增加本级连接下级的中间横线
var tr4 = utils.functionComment(function () {/*
<tr class="tr-hline">
<td colspan="1">
<table width="100%" height="100%" border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td width="50%" style="background:url(rootPath/content/images/tree/Tree_Empty.gif)"></td>
<td width="3px" height="3px" ><img src="rootPath/content/images/tree/Tree_Dot.gif" border="0"></td>
<td width="50%" style="background:url(rootPath/content/images/tree/Tree_Dot.gif)"></td>
</tr>
</tbody>
</table>
</td>
<td style="background:url(rootPath/content/images/tree/Tree_Dot.gif)" colspan="{0}"></td>
<td colspan="1">
<table width="100%" height="100%" border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td width="50%" style="background:url(rootPath/content/images/tree/Tree_Dot.gif)"></td>
<td width="3px" height="3px" ><img src="rootPath/content/images/tree/Tree_Dot.gif" border="0"></td>
<td width="50%" style="background:url(rootPath/content/images/tree/Tree_Empty.gif)"></td>
</tr>
</tbody>
</table>
</td>
</tr>*/});
tr4 = tr4.replace(/rootPath/g,rootPath);
tr4 = utils.formatString(tr4, colspan - 2);
$(tr4).appendTo(tb);
}
//5.递归增加下级所有子节点到图表
if (length > 0) {
var tr5 = $('<tr></tr>');
for (var i in node.children) {
if (i > 0) {
$('<td> </td>').appendTo(tr5);
}
$('<td style="vertical-align:top;text-align:center;"></td>').append(createChild(node.children[i], true)).appendTo(tr5);
}
tr5.appendTo(tb);
}
return tb;
}

1. 访问：http://localhost:8080/ims/sys/organize.do
2. 选择一个机构，点击 设置角色
