extjs 绑定键盘事件。
1》var siteName = new Ext.form.Field({
            id: 'siteName1',//表单元素最好使用Id，不然在IE浏览器中表单内容将变形
            fieldLabel: '网站名称',
            listeners : {
                specialkey : function(field, e) {
                    if (e.getKey() == Ext.EventObject.ENTER) {
                        alert("终于可以回车提交了");
                        ...
                    }
                }
            }
        });


2》       xtype : 'textfield',
       fieldLabel : '搜索',
       id : "sarchdeptName",
       value : '1101',
       anchor : '100%',
       listeners : {
        'render' : function(input) {
         new Ext.KeyMap(input.getEl(), [{
              key : 13,
              fn : SysDeptView.searchDept,
              scope : this
             }]);
        }
       }
      }

SysDeptView.searchDept方法如下:

SysDeptView.searchDept = function() {




3》

Ext.onReady(function(){

Ext.create('Ext.form.Panel', {
    title: 'Simple Form',
    bodyPadding: 5,
    width: 350,

    // Fields will be arranged vertically, stretched to full width
    layout: 'anchor',
    defaults: {
        anchor: '100%'
    },

    // The fields
    defaultType: 'textfield',
    items: [{
        fieldLabel: 'First Name',
        name: 'first',
        allowBlank: false,
listeners : { 
                 specialkey : function(field, e) { 
                     if (e.getKey() == Ext.EventObject.ENTER) { 
                        alert("回车事件"); 
                     }
