我有一个带有actionColumn的网格，当我点击编辑图标时，它应该调用另一个表单（已经可用），其中数据填充到数据库中的字段，以便用户可以编辑和保存它。我是Extjs的新手请帮忙
我尝试使用以下代码，但它不起作用：
myForm.getForm().load({
url: '/.RetrieveRecords',
params: { id: id},
method: 'POST',
waitMsg: 'Loading data...'
这是我的form1：
Ext.application({

这是我的Form2 with Actioncolumns：
Ext.onReady(function()

var store=Ext.create('Ext.data.Store',

autoload: true,
autosync: true,

fields:

{name: 'firstname', id:'firstname'},
{name: 'email', id:'email'},
{name: 'mobileno', id:'mobileno'}
]
});
Ext.create('Ext.grid.Panel',

myForm.getForm().load({

Ext.create('Ext.grid.plugin.CellEditing',

})
],

afterrender:function()
{
Ext.Ajax.request(
{
params:{email:email},

success: function(response)
{
data = [];
data = Ext.JSON.decode(response.responseText);
Ext.getCmp('grid1').getStore().loadData(data);
},
failure: function(response)
{
Ext.Msg.alert("failure" + " " + response.status);
}
});
}
}
});
});
答案 0 :(得分：0)
尝试按下编辑按钮：
handler: function(grid, rowIndex, colIndex, e) {
var rec = grid.getStore().getAt(rowIndex);
myForm.loadRecord(rec);
}
