之前在用easyUI的时候遇到一个问题，一直困扰着我。
问题：
使用dialog来实现保存和编辑框，使用dialog.(“close”)来关闭dialog框，这个时候如果有两个页面的保存页面的表单的字段相同时，这两个表单的东西就会混乱。要不就是保存时打不开，要不就是编辑页面打开数据初始化不了。
解决思路：
使用close的方法来关闭dialog时，此dialog并不是完全消失，只是隐藏起来了而已。当另外一个dialog和这个dialog相同 时，就会发生混乱。所以我们不适用close的方法来关闭dialog，使用destroy来销毁dialog，当使用destroy时，如果页面上显式 定义了dialog的话，关闭后就永远都打不开了。所以我们不显式定义dialog，并且把保存页面和列表页面分开。
解决代码如下：
