Question

长篇文章的Aplogies。这是问题的延续： Extjs adding multiple items to a window does not work 在这个问题中，我有一个这样定义的网格：

var updater = msgDetailsPanel.getUpdater();/*Added new*/


var detailGrid = new Ext.grid.GridPanel({
id:'detailGrid',
store: dataStore,
collapsible: false,
columnLines: false,
enableHdMenu: false,
header: false,
cm: new Ext.grid.ColumnModel({
defaults: {
sortable: true
},
{id:'msgId',hidden: true, dataIndex: 'msgId'},                  
{sortable: true, dataIndex: 'deliveryAddr'},
{sortable: true, dataIndex: 'deliveryDate'},
{sortable: true, dataIndex: 'status', renderer:function(value, p, record){
return String.format( '<font color="009966">{0}</font>', value );}},
{header: 'info',xtype: 'templatecolumn',tpl: '<a href="#"  onClick = "alert({msgId})">View Message Details</a>'}  
]
}),
viewConfig: {
forceFit:true
},
columnLines: false,
frame:false,
collapsible: false,
animCollapse: false,
title: alertName,
disableSelection: true,
deferRowRender:false
});

我希望将onClick = "alert({msgId})"替换为onClick = "updater.update({msgId})"因此，点击超级链接“查看邮件详细信息”，Panel将填充msgId。但我明白了：

javascript error: this.ds.fields.get(...).name is null or not an object.

我怎样才能做到这一点？

由于你的ID（'msgId'）是硬编码的，我建议一个简单的方法：

Ext.onReady( function()
{
    // When the DOM is ready, establish a handler (onClick) for the msgId node.
    // Again, msgId is hardcoded - not certain why you would pass it as a parameter to updater - 
    // but createDelegate passes msgId as a parameter.
    Ext.get('msgId').on( 'click', updater.update.createDelegate( this, [{msgId}], 0 ))
});
