這里是將gooflow的代碼簡單的改造一下，點擊線、點、圖標、區(qū)域的時候彈出新窗口，在新窗口中可以添加設(shè)置更多的信息?？傢撁嫒缦?#xff1a;

文件的目錄，這里吧Gooflow的一套東西都放在GooFlow文件夾下面，文件夾是我自己分的，大家可以按照自己的習(xí)慣去調(diào)整，放到一起便于管理和修改。

code：放置的是彈出的屬性頁面，里面建了幾個文件，預(yù)備和數(shù)據(jù)庫操作相關(guān)聯(lián)，不過例子中并沒有寫代碼，這些代碼可以根據(jù)你建的數(shù)據(jù)庫和三層自己寫添刪改查。

codebase和js：放置的gooflow用的js和css。

demo.html:流程設(shè)計器的主頁面，使用的時候直接調(diào)用。

javaScript/layer：存放的是彈出層的js和css，這是一個獨立的控件，它有自己官網(wǎng)，有興趣的可以自己研究。

主要修改的是GooFlow.js,你可以通過查找alert去看我寫的一些備注，里面關(guān)于圖標點擊、移動等事件都標注出來了。

demo代碼講解： 根據(jù)屏幕顯示編輯區(qū)域的大小 var hight = $(window).height() - 20;
?var width = $(window).width() - 40;
初始化編輯器 $(document).ready(function ()
初始化數(shù)據(jù)json：jsondata，?demo.loadData(jsondata);這個通過ajax從數(shù)據(jù)庫獲得。
左上角的操作按鈕事件接口： demo.onBtnNewClick = function () { alert("新建"); demo.clearData(); };
? ? ? ? ? ? demo.onBtnOpenClick = function () { alert("打開"); };
? ? ? ? ? ? demo.onBtnSaveClick = function () { alert("保存"); alert(JSON.stringify(demo.exportData())); };
? ? ? ? ? ? demo.onFreshClick = function () {
? ? ? ? ? ? ? ? alert("重載"); demo.clearData(); demo.loadData(jsondata);
? ? ? ? ? ? };

顯示編輯窗口js方法： function ShowEdit(id, Type)

layer.open彈出窗口

實現(xiàn)保存： SaveNode(Flag, Value, Type)，只提供簡單的接口代碼。

例如，在在UpdateNode.aspx頁面，也是使用js，先根據(jù)傳遞的節(jié)點信息賦值，然后save是保存，調(diào)用父頁面的方法SaveNode： <script type="text/javascript">
? ? ? ? var node = '<%=Request["node"]%>';
? ? ? ? $(function () {
? ? ? ? ? ? $("input[id$='txtName']").val(node.split(',')[1]);
? ? ? ? ? ? $("input[id$='txtLeft']").val(node.split(',')[2]);
? ? ? ? ? ? $("input[id$='txtTop']").val(node.split(',')[3]);
? ? ? ? ? ? $("input[id$='txtWidth']").val(node.split(',')[4]);
? ? ? ? ? ? $("input[id$='txtHeight']").val(node.split(',')[5]);
? ? ? ? })
? ? ? ? function Save(Type, This) {
? ? ? ? ? ? var Value = $(This).val();
? ? ? ? ? ? parent.SaveNode(Type, Value, "node");
? ? ? ? }
? ? </script>

遺留問題 demo.moveNode(Editid, Editnode.left, Value);
使用此方法后連線會變亂,點一下節(jié)點的突變就會正常，不知道什么原因，個人覺得大小和寬高在設(shè)計器中設(shè)置方便，此方法可以不用。如果有哪位伙伴知道原因，也可以留言告知，謝謝.
在例子中也提供有設(shè)計器的API文檔： http://download.csdn.net/detail/xumengmeng_xu/9809276
