mini.open之后关闭按钮点击出错

狼王不朽

open一个窗口，窗口界面上有一个按钮，点击是一个ajax操作，从后台获取数据.html()赋值，之后点击右上角的关闭按钮，报错如下： VM10087 miniui.js:13 Uncaught TypeError: Cannot set property '_destroying' of null     at mini_unload (miniui.js?v=1.2.1909.0:13)     at miniui.js?v=1.2.1909.0:13     at dispatch (jquery-1.8.2.min.js?v=1.2.1909.0:2)     at h (jquery-1.8.2.min.js?v=1.2.1909.0:2)     at ooO1O1.loOOll [as Ol001O] (miniui.js?v=1.2.1909.0:13)     at ooO1O1.l0101 (miniui.js?v=1.2.1909.0:13)     at ooO1O1.ooo1 [as destroy] (miniui.js?v=1.2.1909.0:13)     at ooO1O1.ooOOOl (miniui.js?v=1.2.1909.0:13)     at ooO1O1.l1l1O [as llol] (miniui.js?v=1.2.1909.0:13)     at ooO1O1.ll1ol [as oOlO1o] (miniui.js?v=1.2.1909.0:13)

这里面获取数据之后有什么操作？
