I have Problem with Store in ExtJS 4. In my application I want to use two combo. A store values are displaying in both combo. But the problem is the value selected in first combo should not get shown in next combo. Due to single store I'm unable to make it happen..What should have to do ?
This Works for me
listeners : {
expand: function() {
boxerListStore.filter(function(r) {
var value = r.get('id');
var getValue = Ext.getCmp('boxer2').getValue();
return (value != getValue);
});
}
}
You can use select event of first combo like -
listeners: {
select: function(combo, records, eOpts){
Ext.getCmp('secondCombo').select(records[0]);
}
}

I have this code in two locations of a page (the post code needs to be displayed twice):
<store-text-field
:store_id="clonedStore.id"
relation="address"
field="post_code"
#value-updated="postCodeUpdated"
:value="clonedStore.address.post_code"/>
Within the component the post_code can be changed and the value passed back to the parent via the value-updated event.
The event code:
postCodeUpdated(value) {
console.log('post code updated to: ' + value)
this.clonedStore.address.post_code = value;
}
Every thing works fine, except the second component does not update with a new value if the post_code is changed in the other.
I expected the value to change as it is binded to this.clonedStore.address.post_code which is changed when the event is detected.
EDIT:
data() {
return {
clonedStore: {
address: {
post_code: ''
}
},
showStoreNameInput: false,
}
},
It's a Reactivity issue you need to use $set for setting value.
try this.
this.$set(this.clonedStore.address,'post_code',value)
While creating a Vue.js application I have become stuck at a weird problem. I want to be able to manipulate an input field (think increment and decrement buttons and erasing a zero value on focus, so the user doesn't have to) and up until a user writes to the input field, everything is fine. After that, however, further changes in the data are no longer represented in the input field.
As I was sure I could not be the only one with this particular problem, I searched extensively, but had no luck. What baffles me the most is that everything works until the field is written to, since I can not really imagine why this would remove the data binding.
The following code should show the same behavior. It is an input field component, which is initialized with a zero value. On focus the zero gets removed. This works, until a user manually writes to the field after which zero values will no longer be removed, even though the focus method fires, the if-condition is met and the data in the amount-variable is changed.
Vue.component('item', {
data: function () {
return {
amount: 0
}
},
render: function (createElement) {
var self = this;
return createElement('input', {
attrs: {
//bind data to field
value: self.amount,
type: 'number'
},
on: {
//update data on input
input: function (event) {
self.amount = event.target.value;
},
//remove a zero value on focus for user convenience
focus: function (event) {
if (self.amount == 0 || self.amount == "0") {
self.amount = '';
}
}
}
})
}
})
I think you need to use domProps instead of attrs to make it reactive. But I would suggest you use vue's template syntax or if you insist on using the render function I would also suggest you to use JSX.
i'm new to Dojo.
I have a "FullEditable" grid, with many columns, and one of them is a widget, it's a ToggleButton. This grid is used to show details of a purchase, so every line represents a product sold. When i click a button inside one of the columns it launches the product (dialog) browser and then the data of that product is passed to the grid. After some work i managed to display the button and being able to set it's label accordingly to the row.data.FIELD value received from that dialog.
But now i am editing that purchase and i need to be able to do the same, to be able to load the data from the preloaded array with data ("detalle") (as it's label) into the togglebutton, but nothing seems to work, not even the direct assignment of the widget or the row data or anything.
Here's a fragment of my code:
var grid = this;
var selectedRow = grid.row(i);
var cell = grid.cell(selectedRow, 'Moneda');
selectedRow.Moneda = detalle.MonedaItem; //didn't work
if(cell.row !== null && cell.row !== undefined && cell.row.data !== null && cell.row.data !== undefined)
cell.row.data.Moneda = detalle.MonedaItem; //didn't work
if(cell.element !== null && cell.element !== undefined){
cell.element.innerText = detalle.MonedaItem; //didn't work
cell.element.textContent = detalle.MonedaItem; //didn't work
if(detalle.MonedaItem === 'UF')
cell.element.widget.set('checked', true);
if(detalle.MonedaItem === 'CLP')
cell.element.widget.set('checked', false);
cell.element.widget.set('label', detalle.MonedaItem); //didn't work
cell.element.widget.set('value', detalle.MonedaItem); //didn't work
}
}
Whenever i set the value through the change event with "cell.element.widget.set('checked', boolean);" i get an error message from the editor, when it tries to get a cell but the variable is null, so it crashes.
The values of "label" and "value" of the widget, row.data en cell are perfectly set, BUT the grid DISPLAYS the "emptyValue" value of the widget and not the one that is actually set.
AFAIK, best way to change the grid data is to update the store/ collection that is associated with the grid and just invoke grid.refresh(). The new data will be loaded automatically.
The statement cell.row.data.Moneda = detalle.MonedaItem is actually changing the data in your store. Just refresh the grid after this and you are done!
Never try to set something in grid DOM element directly. Always work with store, renderCell and renderColumn. This will ensure consistency in store and grid attributes that reference the store.
I finally managed to get what i need through renderCell like this:
,{
id: 'Moneda',
field: 'Moneda',
label: "Moneda",
renderCell: function (object, value, node, options) {
try {
var button = new ToggleButton({
node: node,
isWidgetInGrid: true,
parameterName: 'codigoMoneda',
label: object.Moneda,
showLabel: true,
onChange: function(newValue){
var grid = this.getParent();
var row = grid.row(this.node);
var data = row.data;
if(this.get('label') === 'CLP')
{
data.Moneda = 'UF';
this.set('label','UF');
this.set('value', 'UF');
}
else
{
data.Moneda = 'CLP';
this.set('label','CLP');
this.set('value', 'CLP');
}
grid.getParent().getParent()._calcularTotales();
}
});
node.appendChild(button.domNode);
}
catch (ex) {
Debug.log(this.declaredClass, arguments, ex);
}
},
emptyValue: 'CLP',
autoSave: true
}
I am using Extjs 4.2 and I have a combo box field on my page. When I am updating this page, I need to show the selected value in the combo box. If I use static data it will work properly, but when I am loading data from the database then data is coming but it is displaying the value (not the label) for the selected combo box.
I have done the work around by using the select method of the combo box, but I need to iterate the store for getting the selected value. The store value does not start at 1 but starts at 100, and the select method of the combo box uses the index for the list.
Below is the code you can check, but this is not working for multiple combo boxes.
var specilizationComboBox = Ext.getCmp("doctorMasterVO.specilizationFkId");
var specilizationValue = 0;
specilizationStore.each(function (record) {
if (record.get('value') != dataRead.dataVO.doctorMasterVO.specilizationFkId) {
specilizationValue = specilizationValue + 1;
}
else {
return false;
}
});
specilizationComboBox.select(specilizationComboBox.store.data.items[specilizationValue]);
Please tell me there is any other way to do this because iterating over the whole store is not a good idea.
Check out these methods:
find
findBy
findRecord
findExact
Basicly what you want to do is something like this:
var myId = dataRead.dataVO.doctorMasterVO.specilizationFkId;
var record = store.findRecord("id", myId);
specilizationComboBox.select(record);
Where "id" is the name of the field you are trying to find a match for in your store.
Note that myRecord could be null if the record is not there or if the store is not properly loaded.
To make sure the store is loaded you could execute the code above in a load handler:
specilizationComboBox.getStore().load({
scope: this,
callback: function(records, operation, success) {
//code goes here
}
});
If you are not sure if the store has loaded you could check the getCount method.
I am using extjs 4.1.1a for developing some application.
I had a form consisting of two combo-boxes and an item-selector.
Based on the value selected in first combo-box , the itemselector will load its data from database. This is working fine.
My problem is, if i reselect the first combo-box the new data will be displayed in itemselector along with previous data displayed in itemseletor .That is previous data displayed in itemselector will remain there itself.
for example: name "test1" consists of ids 801,2088,5000. on selecting test1 in firstcombobox itemselector must show output as below.
and if "test2" consists of ids 6090,5040. on selecting test2 in firstcombobox itemselector must show output as below.
problem is. for first time if i select "test1" from firstcombobox , output will come as expected. if i reselect "test2" from firstcombobox , output will come as below.
as you can see, previous data displayed (marked in red rectagle) remains there itself with new data displayed (marked with green rectangle).
I want for every reselection of first combobox, previously displayed data in itemselector to be erased before printing new data on itemselector.
How can I reset the itemselector for every reselection of first combobox?
You should remove all items from the store of the itemselector by the removeAll command. After that you should load the store of the itemselector.
itemselector.store.removeAll();
itemselector.store.load();
Any solutions above solve my problem.
i found solution from Sencha Forum.
https://www.sencha.com/forum/showthread.php?142276-closed-Ext-JS-4.0.2a-itemselector-not-reloading-the-store
in the itemselector.js file, change the line marked below.
populateFromStore: function(store) {
var fromStore = this.fromField.store;
// Flag set when the fromStore has been loaded
this.fromStorePopulated = true;
// THIS LINE BELOW MUST BE CHANGED!!!!!!!!!!!!
fromStore.loadData(store.getRange()); //fromStore.add(store.getRange());
// setValue waits for the from Store to be loaded
fromStore.fireEvent('load', fromStore);
},
You need to insert...
this.reset();
at the head of the function that is inserting the data.
As an example...
Ext.override( Ext.ux.ItemSelector, {
setValue: function(val) {
this.reset();
if (!val) return;
val = val instanceof Array ? val : val.split(this.delimiter);
var rec, i, id;
for (i = 0; i < val.length; i++) {
var vf = this.fromMultiselect.valueField;
id = val[i];
idx = this.toMultiselect.view.store.findBy(function(record){
return record.data[vf] == id;
});
if (idx != -1) continue;
idx = this.fromMultiselect.view.store.findBy(function(record){
return record.data[vf] == id;
});
rec = this.fromMultiselect.view.store.getAt(idx);
if (rec) {
this.toMultiselect.view.store.add(rec);
this.fromMultiselect.view.store.remove(rec);
}
}
}
});
are u got it?
when u select that combobox frist stoe of item selector is null after store load with ur pass the para meters
for example
store.load(null),
store.proxey.url='jso.php?id='+combobox.getrawvalue(),
store.load();
like that so when ur select a value in ur combobox that time ur used a listeners to ur combobox in that listners ur used above code , select ur some value in combobox that time frist store is get null after ur pass some values to json.php then store load with responce so that time old data is remove and new data load in that store
if u post ur code i will give correct code
I ran into the same issue with ExtJS 4.2.1. I got it to work by calling reload() on the data store and then setValue() with an empty string on the item selector in the data store's reload() callback.
Ext.create("Ext.form.field.ComboBox", {
// Other properties removed for brevity
listeners: {
change: function(field, newValue, oldValue, eOpts) {
Ext.getStore("ExampleStore").reload({
callback: function() {
Ext.getCmp("ExampleItemSelector").setValue("");
}
});
}
}
});
Ext.create("Ext.data.Store", {
storeId: "ExampleStore",
// Other properties removed for brevity
});
Ext.create("Ext.form.FormPanel", {
// Other properties removed for brevity
items:[{
xtype: "itemselector",
id: "ExampleItemSelector",
// Other properties removed for brevity
}]
});
For any folks that are curious, I'm fairly convinced there's a bug in the item selector's populateFromStore() function. When the function is called, it blindly adds all of the values from the bound store (store) to the internal store (fromStore). I suspect there should be a call to fromStore.removeAll() prior to the call to fromStore.add(). Here's the relevant code from ItemSelector.js.
populateFromStore: function(store) {
var fromStore = this.fromField.store;
// Flag set when the fromStore has been loaded
this.fromStorePopulated = true;
fromStore.add(store.getRange());
// setValue waits for the from Store to be loaded
fromStore.fireEvent('load', fromStore);
},
EDIT 12/18/2013
If you've configured any callback events on the item selector (e.g. change), you may want to disable the events temporarily when you call setValue(""). For example:
var selector = Ext.getCmp("ExampleItemSelector");
selector.suspendEvents();
selector.setValue("");
selector.resumeEvents();
I had the same problem and finally I decided to modify the extjs source code, not considering it a big issue as extjs itself its saying in the start of the file
Note that this control will most likely remain as an example, and not as a core Ext form
control. However, the API will be changing in a future release and so should not yet be
treated as a final, stable API at this time.
Based on that, as jstricker guessed (and sadly I didn't read and took me a while to arrive to the same conclusion), adding fromStore.removeAll() before fromStore.add() solves the problem.
Outside of the problem (but I think it can be interesting as well), additionally, I also added listConfig: me.listConfig in the MultiSelect configuration (inside createList), that way it's possible to format each item additional options (such as images, etc.) setting in the 'itemselector' the option listConfig as it's explained in the (irrealistic) documentation.
Need to reset the store used in ItemSelector that can be done by setting Empty object like below. Also need to call clearValue() method of ItemSelector component.
store.setData({});
ItemSelectorComponent.clearValue();
