这也像提示框一样，但它允许用户输入多行信息而不是一行。

语法 (Syntax)

以下是一个简单的语法。

Ext.MessageBox.show ({
   title: 'Details',
   msg: 'Please enter your details:',
   width:300,
   buttons: Ext.MessageBox.OKCANCEL,
   multiline: true,    // this property is for multiline user input.
   fn: callbackFunction
});

例子 (Example)

以下是一个显示用法的简单示例。
