We are using treepanel with check box in our application.It seems like:
var treepanel = {
id : 'tree',
xtype : 'treepanel',
store : layerStore,
rootVisible : false,
listeners : {
checkchange : function(node,check){
if(node.get('id') == 'teacher'){
alert('you have selected teacher node');
}else if(node.get('id') == 'student'){ alert('you have selected student node'); }
}
}
};
LayerStore code:
var layerStore = Ext.create('Ext.data.TreeStore',{
root : {
children : [
{
text : 'teacher layer',
id : 'teacher',
checked : false
},{
text : 'Student layer',
id : 'student',
checked : false
}]
}
});
Now,i am getting the alert message when we check on the particular checkbox.My problem is that if we uncheck the checkbox then it has to display the alert like you has unselected a particular layer.Please help me.
I quess You have to change your 'checkchange' handler to this:
checkchange : function(node,check){
var s = (!check && 'un' || '' ) + 'selected';
if(node.get('id') == 'teacher'){
alert('you have '+s+' teacher node');
}else if(node.get('id') == 'student'){ alert('you have '+s+' student node'); }
}

I have the code below to create a text field in the form.
buildForm : function() {
this.time = new Ext.form.TextField({
name : 'estimate',
allowBlank : false,
fieldLabel : 'Estimate',
onBlur : function(field) {
return this.setValue(this.getValue().replace('.', ','));
}
});
}
It works correctly.
Now, when I render this form, and in this field is value="abc", I need to set disabled to this field.
I tried:
disabled : function() { return this.getValue() == 'abc' ? true : false;}
disabled : function(field) { return this.getValue() == 'abc' ? true : false;}
disabled : function(field) { return field.getValue() == 'abc' ? true : false;}
disabled : this.getValue() == 'abc' ? true : false
But nothing of this work. Any idea?
Try this
change: function(field, newValue,) {
field.setDisabled(newValue == 'abc');
}
Check API for more info on events, methods for TextField
UPD:
If you need to disable textfield only on form render, just add this line in buildForm function.
this.time.setDisabled(this.time.getValue() == 'abc')
Another way is to add logic on TextField's render event.
render: function(field) {
field.setDisabled(field.getValue() == 'abc')
}
UPD 2:
I suppose, that your issue is on way of setting value or in the order.
Here's a working sample.
Notice this.time.setValue('abc')
instead of this.time.value = 'abc', which won't work.
buildForm: function() {
this.timeFld = Ext.create('Ext.form.TextField', {
name: 'estimate',
allowBlank: false,
fieldLabel: 'Estimate',
onBlur: function(field) {
return this.setValue(this.getValue().replace('.', ','));
},
listeners: {
render: function(field) {
field.setDisabled(field.getValue() == 'abc');
}
}
});
this.timeFld.setValue('abc');
// this.time.setDisabled(this.time.getValue() == 'abc');
Ext.create('Ext.form.Panel', {
title: 'Test',
items: [
this.timeFld
],
renderTo: Ext.getBody()
});
// alert(this.timeFld.getValue());
}
I have combo box and type head true. On change event I am making ajax request to get matched result.
If type there then its working fine, But If I do copy paste in the Combo then it shows result but gives and error and blocks further flow.
below is the code.
{
xtype : 'combo',
emptyText : 'Search',
id : 'search',
store : Store,
width : '50%',
minChars : 3,
typeAhead : true,
anchor : '100%',
listConfig : {
emptyText : 'No Matching results found.',
getInnerTpl: function() {
return '<div class="search">' +
'<span>{value} - {key}</span>'+
'</div>';
}
},
listeners : {
beforequery: function (record) {
// Added Condition to avoid weird JS error
if(Ext.getCmp('search').getValue() != null && Ext.getCmp('search').getValue().length <= 4){
return false;
}
},
select : function(combo, selection){
var selectedVal = selection[0].data.value;
Ext.getCmp('search').setValue( selectedVal );
},
change : function () {
if( Ext.getCmp('search').getValue() != null && Ext.getCmp('search').getValue().length > 4 ){
var searchEle = Ext.getCmp('search');
var searchType = Ext.getCmp('searchBy').getValue();
var searchText = '%';
searchText += searchEle.getValue();
Ext.Ajax.request({
loadMask : true,
url : URL,
method : 'GET',
params : {
searchText : searchText,
searchType : searchType,
},
scope : this,
success : function( response, callOptions ) {
var myTempData = Ext.decode( response.responseText );
Store.setProxy({
type : 'memory',
data : myTempData,
reader : {
type : 'json',
root : 'data',
totalProperty : 'total',
successProperty : 'success'
}
});
Store.load({
scope : this,
callback : function(records, operation, success) {
}
});
},
failure : function(response, options ) {
loadmask.hide();
Ext.Msg.alert( 'Error', genericErrorMsg );
}
});
}
}
}
The error is as below
The help is greatly appreciated. Thanks.
Json response
{"value":"Test , user # IB Tech: Strategic Change","key":"45804183"},
Finally I solved it.
There was some problem with store.
I bind it after ajax success and removed it from initial config and it got solved.
Store.load({
scope : this,
callback : function(records, operation, success) { }
});
Ext.getCmp('search').bindStore(Store);
I have two ng-grids living in the same $scope, they both have a column of editable cells, ie: enableCellEdit: true
I know I can handle the triggered event like this:
$scope.$on('ngGridEventEndCellEdit', function(event) {
var product = event.targetScope.row.entity;
console.log(product);
});
Question is.. how do I know which grid triggered the event? both grids consume different lists (data attribute of the grid), but these lists contains instances of the same type.
Is there any property inside event that contains the id of the grid?
I had the same trouble and worked around it.
I have three grids and on each cellEditableTemplate I register the ng-click on the cell, thus selecting the next source of the start and end event of the cell edit. The setMethod() that just sets the global variable $scope.thisGridUpdate
$scope.targetTypeDefs = [ {
field : 'id',
displayName : '#',
enableCellEdit : false,
width : 50
}, {
field : 'desc',
displayName : 'Type Description',
enableCellEdit : true,
cellEditableCondition : 'row.selected',
editableCellTemplate : '<input ng-class="\'colt\' + col.index" \
ng-input="COL_FIELD" \
ng-model="COL_FIELD" \
ng-model-options="{ updateOn : \'default blur\' }" \
ng-click="setMethod(\'saveTargetType\')"/>'
} ];
$scope.targetTypeGrid = {
data : 'targetTypeData',
showSelectionCheckbox : true,
selectWithCheckboxOnly : true,
multiSelect : false,
enableCellEditOnFocus : true,
columnDefs : 'targetTypeDefs'
};
Next you just catch and trap the end cell edit events in your normal ngGridEventEndCellEdit event consumer, like this:
$scope.setMethod = function(name) {
console.log("clicked on ", name);
$scope.thisGridUpdate = name;
};
$scope.$on('ngGridEventEndCellEdit', function(evt, other) {
console.log("ended edit on ", $scope.thisGridUpdate, "with " , evt.targetScope.row.entity);
console.log(evt.targetScope.row);
if ($scope.thisGridUpdate === 'saveServerType') {
EntityMgt.saveServerType(evt.targetScope.row.entity);
}
else if ($scope.thisGridUpdate === 'saveOsVersion') {
EntityMgt.saveOsVersion(evt.targetScope.row.entity);
}
else if ($scope.thisGridUpdate === 'saveTargetType') {
EntityMgt.saveTargetType(evt.targetScope.row.entity);
}
});
Am trying to put a search field with respect to a data view. There is a toolbar on top of the data view, which consists of a text field. On entering some text in the field, i want to call a search functionality. As of now, i have got hold of the listener to the text field, but the listener is called immediately after the user starts typing something in the text field.
But, what am trying to do is to start the search functionality only when the user has entered at least 3 characters in the text field.How could i do this?
Code below
View
var DownloadsPanel = {
xtype : 'panel',
border : false,
title : LANG.BTDOWNLOADS,
items : [{
xtype : 'toolbar',
border : true,
baseCls : 'subMenu',
cls : 'effect1',
dock : 'top',
height : 25,
items : [{
xtype : 'textfield',
name : 'SearchDownload',
itemId : 'SearchDownload',
enableKeyEvents : true,
fieldLabel : LANG.DOWNLOADSF3,
allowBlank : true,
minLength : 3
}],
{
xtype : 'dataview',
border : false,
cls : 'catalogue',
autoScroll : true,
emptyText : 'No links to display',
selModel : {
deselectOnContainerClick : false
},
store : DownloadsStore,
overItemCls : 'courseView-over',
itemSelector : 'div.x-item',
tpl : DownloadsTpl,
id : 'cataloguedownloads'
}]
Controller:
init : function() {
this.control({
// reference to the text field in the view
'#SearchDownload' :{
change: this.SearchDownloads
}
});
SearchDownloads : function(){
console.log('Search functionality')
}
UPDATE 1: i was able to get hold of the listener after three characters have been entered using the below code:
Controller
'#SearchDownload' :{
keyup : this.handleonChange,
},
handleonChange : function(textfield, e, eOpts){
if(textfield.getValue().length > 3){
console.log('Three');
}
}
any guidance or examples on how to perform the search in the store of the data view would be appreciated.
A proper way would be to subscribe yourself to the change event of the field and check if the new value has at least 3 chars before proceeding.
'#SearchDownload' :{ change: this.handleonChange }
// othoer code
handleonChange : function(textfield, newValue, oldValue, eOpts ){
if(newValue.length >= 3){
console.log('Three');
}
}
Btw. I recommend you to use lowercase and '-' separated names for id's. In your case
itemId : 'search-download'
Edit apply the filter
To apply the filter I would use filter I guess you now the field you want to filter on? Lets pretend store is a variable within your controller than you may replace the console.log() with
this.store.filter('YourFieldName', newValue);
Second param can also be a regex using the value like in the example
this.store.filter('YourFieldName', new RegExp("/\"+newValue+"$/") );
For sure you can also use a Function
this.store.filter({filterFn: function(rec) { return rec.get("YourFieldName") > 10; }});
Thanks you so much sra for your answers. Here is what i did, based on your comments
filterDownloads : function(val, filterWh){
if(filterWh == 1){
var store = Ext.getStore('CatalogueDownloads');
store.clearFilter();
store.filterBy(function (r){
var retval = false;
var rv = r.get('title');
var re = new RegExp((val), 'gi');
retval = re.test(rv);
if(!retval){
var rv = r.get('shortD');
var re = new RegExp((val), 'gi');
retval = re.test(rv);
}
if(retval){
return true;
}
return retval;
})
}
}
i think there is an example of exactly what you are trying to achive .. http://docs.sencha.com/ext-js/4-0/#!/example/form/forum-search.html
Am having a tree panel in my view, and its corresponding controllers. What is happening is that am having two controllers, one for the itemdblclick and another for itemmove. The itemdblclick is working ok, but when i add the controller for itemmove, itemmove is working, but on the other hand, itemdbclick is not working. And if i remove the itemmove controller, itemdblclick is working. Hope am not confusing:) In simple words, the two controllers are working separately but not together.
Could anyone please tell me what am i doing wrong here.
Also, in the function editRegion in the controller, am trying to reload the tree by using the getStore.load() method, but the tree is not loading even though am able to see the store being invoked in the firebug
EDIT:
Am opening a form on double-clicking the tree node, and on closing the form, i want the tree panel to be reloaded. This is what i want to happen in editregion function
View
{
xtype : 'treepanel',
title : '',
id : 'hierarchyTree',
border : false,
alias : 'widget.hierarchyTree',
height : 1000,
viewConfig : {
enableDD : true,
plugins : {
ptype : 'treeviewdragdrop'
}
},
collapsible : false,
useArrows : true,
rootVisible : false,
store : Ext.create('App.store.HierarchyTree'),
displayField : 'Title',
multiSelect : false,
singleExpand : false,
}
Controller
refs : [{
ref : 'myHierarchyTree',
selector : '#hierarchyTree'
}
init : function() {
this.getHierarchyTreeStore().load();
'#hierarchyTree' : {
itemdblclick : this.itemdblclick
},
'#hierarchyTree' : {
itemmove : this.itemmove
}
itemdblclick : function(view, record, level) {
if (record.get('LevelID') == 1) {
this.erWin = Ext.create('App.view.EditRegions');
var f = this.getEditregionform().getForm();
f.loadRecord(record);
this.erWin.showWin();
}
else if (record.get('LevelID') == 2) {
this.eaWin = Ext.create('App.view.EditAreas');
var f = this.getEditareaform().getForm();
f.loadRecord(record);
this.eaWin.showWin();
}
itemmove : function(v, oldParent, newParent, index, eOpts) {
var nodeID = v.data.id;
var oldParent = oldParent.data.id;
var newParent = newParent.data.id;
var index = index;
var level = v.data.LevelID;
Ext.Ajax.request({
url : 'data/Locations.aspx',
params : {
mode : 'MOVENODE',
currentNode : nodeID,
oldParentNode : oldParent,
newParentNode : newParent
},
success : function() {
alert(LANG.SUC);
Ext.getStore('HierarchyTree').load();
},
failure : function() {
}
});
editRegion : function(button, record) {
var fp = button.up('form');
if (fp.getForm().isValid()) {
fp.getForm().submit({
url : 'data/Locations.aspx',
params : {
mode : 'EDITREGION',
userID : ME.UserID,
RegionID : ME.RegionID
},
success : function(response) {
alert(LANG.SUC);
this.getHierarchyTreeStore().load();
},
failure : function(response) {
alert('Try again');
}
});
}
}
adding them separately will cause the first listener object to be overridden.
Fix:
'#hierarchyTree' : {
itemdblclick : this.itemdblclick,
itemmove : this.itemmove
},
You should check if the store is the same. Meaning check the id because i think the contoller initializes one store and the panel another. so check if this.getHierarchyTreeStore().id is equal with the one from treepanel. you can navigate to it from the button something like button.up().down('treepanel').getStore().id. If they are different then you should use the second method to get the store.
tried doing the following code, as using up and down will not refer to the correct view, since the tree and the forms are completely different views
var view = Ext.widget('hierarchy');
view.down('treepanel').getStore.load();
Now, even though the store is re-loading, am geting an error
TypeError: view.down("treepanel") is null
view.down('treepanel').getStore.load();
