Ext.js：多行用户输入框

这也像提示框，但它允许用户输入多线信息，而不只是一行。

语法

这里是简单的语法。

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

      Ext.onReady(function() {
         Ext.create('Ext.Button', {
            renderTo: Ext.getElementById('msgBox'),
            text: 'Click Me',
            listeners: {
               click: function() {
                  Ext.MessageBox.show({
