如何筛选ExtJs GridPanel / ExtJs商店？(How to filter ExtJs GridPanel/ExtJs Store?)
我是ExtJs的新手。 我有一个与
data store绑定的GridPanel。 我有一个checkboxgroup，它包含GridPanel行的可能值。 我想用checkboxgroup值过滤GridPanel。这里是代码 -
Store1 = new Ext.data.JsonStore({ url: 'CustomerProfiles/GetDetails', root: 'rows', fields:['Name','Id'] }); DetailedResults = { xtype: 'grid', autoHeight: true, autoWidth: true, autoScroll: true, border: false, trackMouseOver: false, frame: true, store: Store1, columns: [ { header: 'Name', dataIndex: 'Name', width: 90 }, { header: 'Id', dataIndex: 'Id', width: 50 } ] }; Leftpanel = new Ext.Panel({ id: 'Leftpanel', frame: true, width: 175, items: [ { xtype: 'label' }, { xtype: 'checkboxgroup', columns: 1, vertical: true, items: [{ boxLabel: 'ALL', name: 'chkName', inputValue: 'all' }, { boxLabel: 'N1', name: 'chkName', inputValue: 'N1' }, { boxLabel: 'N2', name: 'chkName', inputValue: 'N2' }, { boxLabel: 'N3', name: 'chkName', inputValue: 'N3' }], listeners: { change: { fn: function () { Store1.clearFilter(); var selectedValue = this.getValue(); for (var i = 0; i < selectedValue.length; i++) { Store1.filter('Name', selectedValue[i].inputValue); } } } } } ]});我哪里出错了？
PS：我正在使用3.4版本
I'm new to ExtJs. I have a
GridPanelwhich is binded with adata store. I have acheckboxgroup, which containts the possible values of theGridPanelrow. I want to filter theGridPanelwith thecheckboxgroupvalues.Here is the code -
Store1 = new Ext.data.JsonStore({ url: 'CustomerProfiles/GetDetails', root: 'rows', fields:['Name','Id'] }); DetailedResults = { xtype: 'grid', autoHeight: true, autoWidth: true, autoScroll: true, border: false, trackMouseOver: false, frame: true, store: Store1, columns: [ { header: 'Name', dataIndex: 'Name', width: 90 }, { header: 'Id', dataIndex: 'Id', width: 50 } ] }; Leftpanel = new Ext.Panel({ id: 'Leftpanel', frame: true, width: 175, items: [ { xtype: 'label' }, { xtype: 'checkboxgroup', columns: 1, vertical: true, items: [{ boxLabel: 'ALL', name: 'chkName', inputValue: 'all' }, { boxLabel: 'N1', name: 'chkName', inputValue: 'N1' }, { boxLabel: 'N2', name: 'chkName', inputValue: 'N2' }, { boxLabel: 'N3', name: 'chkName', inputValue: 'N3' }], listeners: { change: { fn: function () { Store1.clearFilter(); var selectedValue = this.getValue(); for (var i = 0; i < selectedValue.length; i++) { Store1.filter('Name', selectedValue[i].inputValue); } } } } } ]});Where I went wrong?

您可以使用DatePickerDialog为我发布示例代码
static final int DATE_DIALOG_ID = 999; DatePickerDialog.OnDateSetListener date; date = new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { // TODO Auto-generated method stub myCalendar.set(Calendar.YEAR, year); myCalendar.set(Calendar.MONTH, monthOfYear); myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth); updateLabel(val); } }; depart.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub showDialog(DATE_DIALOG_ID); val = 1; } }); protected Dialog onCreateDialog(int id) { final Calendar now = Calendar.getInstance(); switch (id) { case DATE_DIALOG_ID: // set date picker as current date DatePickerDialog _date = new DatePickerDialog(this, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)) { @Override public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) { if (year - now.get(Calendar.YEAR) > 1) { view.updateDate(year - 1, myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } if (year - now.get(Calendar.YEAR) == 1 && monthOfYear > now.get(Calendar.MONTH)) { view.updateDate(year, myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } if (year - now.get(Calendar.YEAR) == 1 && monthOfYear == now.get(Calendar.MONTH) && dayOfMonth > now.get(Calendar.DAY_OF_MONTH)) { view.updateDate(year, myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } if (year < now.get(Calendar.YEAR)) view.updateDate(myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); if (monthOfYear < now.get(Calendar.MONTH) && year == now.get(Calendar.YEAR)) view.updateDate(myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); if (dayOfMonth < now.get(Calendar.DAY_OF_MONTH) && year == now.get(Calendar.YEAR) && monthOfYear == now.get(Calendar.MONTH)) view.updateDate(myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } }; return _date; } return null; }设置日期：
private void updateLabel(int val) { String myFormat = "dd/MM/yy"; // In which you need put here SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US); Log.d("Date value ", "===" + sdf.format(myCalendar.getTime())); depart.setText(sdf.format(myCalendar.getTime())); }You can use DatePickerDialog for this i am posting a sample code for you
static final int DATE_DIALOG_ID = 999; DatePickerDialog.OnDateSetListener date; date = new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { // TODO Auto-generated method stub myCalendar.set(Calendar.YEAR, year); myCalendar.set(Calendar.MONTH, monthOfYear); myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth); updateLabel(val); } }; depart.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub showDialog(DATE_DIALOG_ID); val = 1; } }); protected Dialog onCreateDialog(int id) { final Calendar now = Calendar.getInstance(); switch (id) { case DATE_DIALOG_ID: // set date picker as current date DatePickerDialog _date = new DatePickerDialog(this, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)) { @Override public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) { if (year - now.get(Calendar.YEAR) > 1) { view.updateDate(year - 1, myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } if (year - now.get(Calendar.YEAR) == 1 && monthOfYear > now.get(Calendar.MONTH)) { view.updateDate(year, myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } if (year - now.get(Calendar.YEAR) == 1 && monthOfYear == now.get(Calendar.MONTH) && dayOfMonth > now.get(Calendar.DAY_OF_MONTH)) { view.updateDate(year, myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } if (year < now.get(Calendar.YEAR)) view.updateDate(myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); if (monthOfYear < now.get(Calendar.MONTH) && year == now.get(Calendar.YEAR)) view.updateDate(myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); if (dayOfMonth < now.get(Calendar.DAY_OF_MONTH) && year == now.get(Calendar.YEAR) && monthOfYear == now.get(Calendar.MONTH)) view.updateDate(myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); } }; return _date; } return null; }To set the Date :
private void updateLabel(int val) { String myFormat = "dd/MM/yy"; // In which you need put here SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US); Log.d("Date value ", "===" + sdf.format(myCalendar.getTime())); depart.setText(sdf.format(myCalendar.getTime())); }
