目标
当用户单击"复制"按钮时,该存储记录将存储到内存中,其"start_time"将设置为当前日期和时间,并将其作为新记录重新插入到存储中
目前的结果
我收到以下JS错误:未捕获的TypeError:无法读取未定义的属性"数据"
我的问题
首先,我甚至不确定我是否正确抓取当前所选行的数据记录.其次,我不知道我得到的错误信息是什么意思.
任何帮助一如既往地受到高度赞赏.
谢谢.
更新1
经过一些调整后,这就是我想出的(这个复制按钮处理程序的修改代码)
{
id: 'actions',
header: null,
xtype: 'actioncolumn',
items: [
{
icon: 'assets/images/silk_icons/page_copy.png',
iconCls: 'action_icon',
handler: function(grid, rowIndex, columnIndex) {
grid.stopEditing();
var newRow = TimeTracker.dataStore.getCount();
var currentRecord = grid.store.getAt(rowIndex);
var timecardEntry = grid.store.recordType;
tce = new timecardEntry(currentRecord.data);
tce.data.start_time = new Date().format('Y-m-d H:i:s');
grid.store.insert(newRow, tce);
}
},
{
icon: 'assets/images/silk_icons/page_delete.png',
handler: function(grid, rowIndex, columnIndex) {
alert('called');
}
}
]
}
这是我正在做的事情:
请批评此代码,如果有更好的方法,请告诉我.谢谢!
更新2:
handler: function(grid, rowIndex, columnIndex) {
grid.stopEditing();
var recordClone = grid.store.getAt(rowIndex).copy();
Ext.data.Record.id(recordClone);
if(recordClone) {
grid.store.add(recordClone);
}
}
我更新了代码以使用副本和添加方法,它确实有效.但是,当我调用add()方法时,我得到'e is undefined error'但是当我刷新页面时,尽管出现错误消息,仍会插入记录.想法？
在我看来，它没有tce正确构建对象。您应该在这一行设置断点：
tce = new timecardEntry(currentRecord.data);
看起来它正在成功构建一个timecardEntry不知何故不是正确的记录。看看它正在构建的东西可能会有所帮助。
如果通过这种方式看不出来为什么它会出现在喷嘴上，请尝试这样做，就像@timdev建议的那样：
var store = grid.store,
currentRecord = store.getAt(rowIndex),
tce;
tce = currentRecord.copy();
tce.set('start_time', new Date().format('Y-m-d H:i:s'));
if (tce) {
store.add(tce);
}
（您应该能够调用grid.store.add(tce)而不是insert在最后插入时调用。）
