dojo的TabContainer中增加的ContentPane如果是closable，如何在关闭后不销毁ContentPane

主要思路是新建TabContainer的扩展类，重载其closeChild属性，使得其在关闭子容器时，不调用该子容器的destroyRecursive方法。

define([ "dojo/_base/declare", "dijit/layout/TabContainer"

], function(declare,TabContainer) {

return declare("comm.comm.ExTabContainer", TabContainer, {

closeChildAction:"destroy",

closeChild: function(/*dijit/_WidgetBase*/ page){

// summary:

// Callback when user clicks the [X] to remove a page.

// If onClose() returns true then remove and destroy the child.

// tags:

// private

var remove = page.onClose && page.onClose(this, page);

if(remove){

this.removeChild(page);

if (this.closeChildAction=="destroy"){

// makes sure we can clean up executeScripts in ContentPane onUnLoad

page.destroyRecursive();

}

}

}

});

});

然后创建TabContainer的方法如下:

var tc=new ExTabContainer({

style : "height: 100%; width: 100%;",

isLayoutContainer : true,

region : 'center',

closeChildAction:"hide"

});
