如何给ext的按钮设置热键？

Question

buttons:[{
text:"取 消",
minWidth:70,
handler:function()
{
    AddPublishwin.hide();
    var jydbh = Ext.getCmp("jydbh").getValue();
    Ext.Ajax.request({         
                url:'DATA/jydbh/Deljydbh.aspx?jydbh='+jydbh,
                success:function(){
                
            }
        })
}
}]button里面有这么个 取消按钮  如何设置热键就像asp中的这样<input type="reset" value="重置(Alt+r)" accesskey="r" >

Answer 1

不行，添加键盘事件看看
Ext.get("butId").dom.onkeydown = function (event) {
    if (event.keyCode == 13) {
         alert("your press enter");
    }
}

buttons:[{
text:"取 消(ctrl+q)",
minWidth:70,
id:"cancel",
handler:function()
{
    AddPublishwin.hide();
    var jydbh = Ext.getCmp("jydbh").getValue();
    Ext.Ajax.request({         
                url:'DATA/jydbh/Deljydbh.aspx?jydbh='+jydbh,
                success:function(){
                
            }
        })
}
},{
        text:"打印预览",
        minwidth:70,
        handler:function()
        {
            //addPublishwin.hide();
        }
},{
        text:"直接打印",
        minwidth:70,
        handler:function()
        {
