In Extjs, I want to know whether I can restrict the dragging of elements within a specific x,y co-ordinates, just like an option, containment in jQuery-UI.
Currently this is my code:
abc.prototype.initDrag = function(v) {
v.dragZone = new Ext.dd.DragZone(v.getEl(), {
containerScroll : false,
getDragData : function(e) {
var sourceEl = e.getTarget(v.itemSelector, 10);
var t = e.getTarget();
var rowIndex = abc.grid.getView().findRowIndex(t);
var columnIndex = abc.grid.getView().findCellIndex(t);
var abcDragZone = v.dragZone ; //Ext.getCmp('idabcDragZone');
var widthToScrollV = $(window).width()-((columnIndex-1)*100);
var widthToScrollH = $(window).height()-((5-rowIndex)*30);
abcDragZone.setXConstraint(0,widthToScrollV);
abcDragZone.setYConstraint(widthToScrollH,0);
if ((rowIndex !== false) && (columnIndex !== false)) {
if (sourceEl) {
abc.isDragged = true;
def.scriptGrid.isDraggableForObject = false;
def.scriptGrid.dragRowIndex = false;
d = sourceEl.cloneNode(true);
d.id = Ext.id();
d.textContent = "\$" + abc.grid.getColumnModel().getColumnHeader(columnIndex);
return {
ddel : d,
sourceEl : d,
sourceStore : v.store
}
}
}
},
getRepairXY : function() {
return this.dragData.repairXY;
},
});
}
But the problem is that the initdrag is called when the csv sheet is added to DOM. Only when its added that element can be accessed and the individual cells' drag limits can be set. So once I add a csv, the limits are not getting set. If I add it again to DOM then the limits work. Is there an option like the jQuery UI containment for draggable, here in extjs?
edit:
I even tried :
constrainTo( constrainTo, [pad], [inContent] )
body had an id of #abc
when I tried with
dragZoneObj.startDrag = function(){
this.constrainTo('abc');
};
which is a method of the DragZone class. It still did not cover the whole body tag.

I'm trying to combine the Isotope multiple checkbox filtering with a searchbox.
I used the example with the checkbox filters from here and tried to implement the searchbox but with no luck.
Just the checkbox filtering works well. I think i'm close to the solution but my javascript skills are at a very beginner level.
I commented out the section of what i've tried to implement.
Thank you for some hints
// quick search regex
var qsRegex;
var $grid;
var filters = {};
var $grid = $('.grid');
//set initial options
$grid.isotope({
layoutMode: 'fitRows'
});
$(function() {
$grid = $('#grid');
$grid.isotope();
// do stuff when checkbox change
$('#options').on('change', function(jQEvent) {
var $checkbox = $(jQEvent.target);
manageCheckbox($checkbox);
var comboFilter = getComboFilter(filters);
/*var searchResult = qsRegex ? $(this).text().match(qsRegex) : true;
var filterResult = function() {
return comboFilter && searchResult;
}*/
$grid.isotope({
filter: comboFilter //or filterResult
});
});
});
function getComboFilter(filters) {
var i = 0;
var comboFilters = [];
var message = [];
for (var prop in filters) {
message.push(filters[prop].join(' '));
var filterGroup = filters[prop];
// skip to next filter group if it doesn't have any values
if (!filterGroup.length) {
continue;
}
if (i === 0) {
// copy to new array
comboFilters = filterGroup.slice(0);
} else {
var filterSelectors = [];
// copy to fresh array
var groupCombo = comboFilters.slice(0); // [ A, B ]
// merge filter Groups
for (var k = 0, len3 = filterGroup.length; k < len3; k++) {
for (var j = 0, len2 = groupCombo.length; j < len2; j++) {
filterSelectors.push(groupCombo[j] + filterGroup[k]); // [ 1, 2 ]
}
}
// apply filter selectors to combo filters for next group
comboFilters = filterSelectors;
}
i++;
}
var comboFilter = comboFilters.join(', ');
return comboFilter;
}
// use value of search field to filter
var $quicksearch = $('.quicksearch').keyup(debounce(function() {
qsRegex = new RegExp($quicksearch.val(), 'gi');
$grid.isotope();
}, ));
// debounce so filtering doesn't happen every millisecond
function debounce(fn, threshold) {
var timeout;
threshold = threshold || 100;
return function debounced() {
clearTimeout(timeout);
var args = arguments;
var _this = this;
function delayed() {
fn.apply(_this, args);
}
timeout = setTimeout(delayed, threshold);
}
}
function manageCheckbox($checkbox) {
var checkbox = $checkbox[0];
var group = $checkbox.parents('.option-set').attr('data-group');
// create array for filter group, if not there yet
var filterGroup = filters[group];
if (!filterGroup) {
filterGroup = filters[group] = [];
}
var isAll = $checkbox.hasClass('all');
// reset filter group if the all box was checked
if (isAll) {
delete filters[group];
if (!checkbox.checked) {
checkbox.checked = 'checked';
}
}
// index of
var index = $.inArray(checkbox.value, filterGroup);
if (checkbox.checked) {
var selector = isAll ? 'input' : 'input.all';
$checkbox.siblings(selector).prop('checked', false);
if (!isAll && index === -1) {
// add filter to group
filters[group].push(checkbox.value);
}
} else if (!isAll) {
// remove filter from group
filters[group].splice(index, 1);
// if unchecked the last box, check the all
if (!$checkbox.siblings('[checked]').length) {
$checkbox.parents('.option-set').find(selector).prop('checked', false);
}
}
I found the solution by myself, but i had to add a second function for returning the searchresult. Otherwise the search function is triggered only after using a checkbox or leaving the search box input field.
How could i avoid this redundand code?
JS:
// use value of search field to filter
var $quicksearch = $('.quicksearch').keyup(debounce(function() {
qsRegex = new RegExp($quicksearch.val(), 'gi');
$grid.isotope();
}, 200));
$(function() {
$grid = $('#grid');
$grid.isotope({
filter: function() {
var searchResult = qsRegex ? $(this).text().match(qsRegex) : true;
return searchResult;
}
});
// do stuff when checkbox change
$('#options').on('change', function(jQEvent) {
var $checkbox = $(jQEvent.target);
manageCheckbox($checkbox);
var comboFilter = getComboFilter(filters);
$grid.isotope({
filter: function() {
var buttonResult = comboFilter ? $(this).is(comboFilter) : true;
var searchResult = qsRegex ? $(this).text().match(qsRegex) : true;
return buttonResult && searchResult;
}
});
});
});
How do I restrict the drag operation not exceeding certain boundary. Is there any config in extjs (version 3), I saw that, Ext.dd.DragZone class is used. But Im not sure what is the usability. I saw a method dropNotAllowed. Is that the method, that has to be used? if so, how should I use that? Please provide some examples.
Im looking for something similar to (jquery UI's draggable containment property)
http://docs.sencha.com/extjs/3.4.0/#!/api/Ext.dd.DragZone-cfg-dropNotAllowed
I tried using the set X and Y constraints, but it did not work-out:
abc.prototype.initDrag = function(v) {
v.dragZoneobj = new Ext.dd.DragZone(v.getEl(), {
getDragData : function(e) {
var sourceEl = e.getTarget(v.itemSelector, 10);
// sourceEl.setXConstraint( 0, 10 );
var t = e.getTarget();
var rowIndex = abc.grid.getView().findRowIndex(t);
var columnIndex = abc.grid.getView().findCellIndex(t);
if ((rowIndex !== false) && (columnIndex !== false)) {
if (sourceEl) {
abc.isDragged = true;
abc.scriptGrid.isDraggableForObject = false;
abc.scriptGrid.dragRowIndex = false;
d = sourceEl.cloneNode(true);
d.id = Ext.id();
d.textContent = sourceEl.innerHTML;
// d.setXConstraint( 0, 10 );
// d.setYConstraint( 0, 10 );
return {
ddel : d,
sourceEl : d,
sourceStore : v.store
}
}
}
},
getRepairXY : function() {
return this.dragData.repairXY;
},
});
}
Both are commented in the above code. The above code is initiated when the panel is rendered.
edit:
How these setX and setYcontraints have to be used?
By default, the element can be dragged any place on the screen. In the doc there are two methods setXConstraint( iLeft, iRight, iTickSize) and setYConstraint( iUp, iDown, iTickSize )
These two methods is used to set to limit the vertical travel and horizental travel of the element.
In Ext.grid.EditorGridPanel table how to split a cell to have two or three rows?
Like the below image
I managed to do a kind of rowspan instead of row splitting. IMO it's easier and it looks the same as grid on attached image. Example code:
var grid = new Ext.grid.EditorGridPanel({
[...],
// hook up events
initComponent: function () {
Ext.grid.GridPanel.prototype.initComponent.call(this);
this.getView().on('refresh', this.updateRowSpan, this);
this.getView().on('rowupdated', this.updateRowSpan, this);
},
onLayout : function(vw, vh) {
this.updateRowSpan();
},
// set span on rows
updateRowSpan: function() {
var columns = this.getColumnModel().config,
view = this.getView(),
store = this.getStore(),
rowCount = store.getCount(),
column = columns[0], // put propert column index here
dataIndex = column.dataIndex,
spanCell = null,
spanCount = null;
spanValue = null;
for (var row = 0; row < rowCount; ++row) {
var cell = view.getCell(row, 0),
record = store.getAt(row),
value = record.get(dataIndex);
if (spanValue != value) {
if (spanCell !== null) {
this.setSpan(Ext.get(spanCell), spanCount);
}
spanCell = cell;
spanCount = 1;
spanValue = value;
} else {
spanCount++;
}
}
if (spanCell !== null) {
this.setSpan(Ext.get(spanCell), spanCount);
}
},
// set actual span on row
setSpan: function(cell, count) {
var view = this.getView(),
innerCell = Ext.get(cell.down('*')),
height = cell.getHeight(),
width = cell.getWidth();
cell.setStyle('position', 'relative');
if (count == 1) {
innerCell.setStyle('position', '');
innerCell.setStyle('height', '');
innerCell.setStyle('height', '');
} else {
innerCell.setStyle('position', 'absolute');
innerCell.setStyle('height', (height * count - cell.getPadding('tb') - innerCell.getPadding('tb')) + 'px');
innerCell.setStyle('width', (width - cell.getPadding('lr') - innerCell.getPadding('lr')) + 'px');
}
}
});
This code changes style of .x-grid3-cell-inner by applying position: absolute and big enough size to cover rows below. Notice that you must also apply some opaque background to make it work. Working sample: http://jsfiddle.net/RpxZ5/8/
I first wrote code for Ext JS 4, if you interested, here is working sample: http://jsfiddle.net/wQSQM/3/
I had a working grid-to-grid drag and drop configuration, but once I changed one of the grids to an EditorGridPanel, I could no longer drag from it - only to it. Once I click on the row I want to drag I get the following error:
sm.isSelected is not a function
if(!sm.isSelected(rowIndex) || e.hasModifier()){
ext-all-debug.js (line 45439)
Is there any way to set it up so I can drag rows from an EditorGridPanel?
Found the answer to this inadvertently while looking at another example.
When creating a EditorGridPanel, be sure to include:
selModel:new Ext.grid.RowSelectionModel({singleSelect:true}),
to get the drag and drop functionality to work.
You don't have to use RowSelectionModel, but you will have to write your own code for the drag and drop zones. Here's an example of how to use drag and drop with CellSelectionModel:
grid1.on('render', function(grid) {grid1.initializeDragZone (grid1); });
grid2.on('render', function(grid) {grid2.initializeDropZone (grid2); });
initializeDragZone : function(grid) {
grid.dragZone = new Ext.dd.DragZone(grid.getEl(), {
getRepairXY: function() {
return this.dragData.repairXY;
},
getDragData: function(e) {
var cell = grid.getSelectionModel().getSelectedCell();
var row = grid.getStore().getAt(cell[0]);
var data = row.get('id'); //you can put custom data here
var sourceEl = grid.getView().getRow(cell[0]);
if (sourceEl) {
var d = sourceEl.cloneNode(true);
d.id = Ext.id();
return grid.dragData = {
sourceEl: sourceEl,
repairXY: Ext.fly(sourceEl).getXY(),
ddel: d,
customData: data //our custom data
};
}
}
});
}
initializeDropZone : function(grid) {
grid.dropZone = new Ext.dd.DropZone(grid.getView().scroller, {
getTargetFromEvent: function(e) { //supports multiple drop zone classes
var target = e.getTarget('.some-class1');
target = target? target: e.getTarget('.some-class2');
target = target? target: e.getTarget('.some-class3');
target = target? target: e.getTarget('.some-class4');
return target;
},
onNodeEnter : function(target, dd, e, data){
Ext.fly(target).addClass('drop-zone-selected'); //test
},
onNodeOut : function(target, dd, e, data){
Ext.fly(target).removeClass('drop-zone-selected'); //test
},
onNodeOver : function(target, dd, e, data){
return Ext.dd.DropZone.prototype.dropAllowed;
},
onNodeDrop : function(target, dd, e, data){
var rowIndex = grid.getView().findRowIndex(target);
var rowRecord = grid.getStore().getAt(rowIndex);
var customData = data.customData;
//use custom data
return true;
}
});
}
how to get the updated records,i am overriding the on Ok function to save changes in form.
1.i just override the on ok function,but not able to get modified record.
Ext.override(Ext.ux.grid.RecordForm , {
onOK:function() {
updateRecord1();
}
});
function updateRecord1() {//alert('record');
var records =store.getModifiedRecords();
if(!records.length) {
return;
}
var data = [];
Ext.each(records, function(r, i) {
var o = r.getChanges();
if(r.data.newRecord) {
o.newRecord = true;
}
o[idName] = r.get(idName);
data.push(o);
});
var o = {
url:gl_acc.php
,method:'post'
,params:{
record:record.get('id'),
task:'update'
}
};
Ext.Ajax.request(o);
} // eo function commitChanges
var records = this.store.getModifiedRecords();
