Filter Object using Lodash - filter

I started learning Lodash and want to filter the following:
{
Cat:false,
Dog: true,
Fish:false
}
I can filter for truth values through the following:
filtered = _.pick(obj, function(value, key) {return value;})
How would I filter for objects with only false values?


filtered = _.pickBy(obj, function(value, key) {return !value;})
Or on the contrary,
filtered = _.omitBy(obj, function(value, key) {return value;})


In your case there is no need of predicate, you can write it shorter:
const obj = {cat:false, dog:true, fish:false}
_.omitBy(obj)
// or
_.pickBy(obj, o => !o)
// or
_.pickBy(obj, _.negate(_.identity))

Cypress automation: multiple cy.get elements in one function

I have a function:
checkWebElemAndAssert(...elements) {
for (const element of elements) {
element.should('be.visible').click().should('be.checked');
}
}
and i use it within another function:
checkRegisterValues = () => {
let maleCheckBox = cy.get('input[value=Male]');
let femaleCheckBox = cy.get('input[value=FeMale]');
let cricketCheckBox = cy.get('#checkbox1');
let registerElemList = [maleCheckBox, femaleCheckBox, cricketCheckBox];
this.browserUtils.checkWebElemAndAssert(...registerElemList);
return this;
}
The problem is that when i use checkRegisterValues() it uses for each action the last element: cricketCheckBox. Any hints on what is wrong? i would expect that the action is made for each element and not the last one.

Have you tried passing in the array like this?
this.browserUtils.checkWebElemAndAssert(registerElemList);
You can also print out
checkWebElemAndAssert(...elements) {
console.log(elements);
for (const element of elements) {
element.should('be.visible').click().should('be.checked');
}
}
and see what you are passing in

ok so i read a bit more and made this:
checkWebElemAndAssert2(elements) {
cy.get(elements).each(($list) => {
cy.get($list).click({ multiple: true }).should('be.checked')
})
}
Basically in elements when i call checkWebElemAndAssert2 i will give the list identifier. Seems to work but not sure meets the standard.
checkRegisterValues = () => {
let myList = 'input[type=radio]';
this.browserUtils.checkWebElemAndAssert2(myList);
return this;
}

How can i compare arrays in Cypress?

I want to compare data present in an array with the data retrieved from a class using .each in cypress?
Using below code i have tried to iterate over the FileType array using below code.
const Filetype = ['Access', 'Excel', 'Text/CSV','PDF','JSON','dsdsd'];
const te = cy.wrap($bodyFind).find('.data-sourcename').should('have.length',6).each(($li) => { cy.log($li.text()); });
te.each(($text)=> {
cy.log("Te" + $text);
//prints ['Access','Excel','Text/CSV','PDF','JSON','XML'];
});
// Converted FileType Array to Cypress object using cy.wrap command.
const cywrap = cy.wrap(Filetype);
te.each((e1)=>cywrap.each((e2)=> {
if(e1 == e2) {
expect(e1).equals(e2);
}
}));
But the value of e1 and e2 is same.
expect should fail with 'dsdsd' is equals 'XML'
whereas it passes with 'dsdsd' is equals 'dsdsd'

You could use map here.
const filetypes = ['Access', 'Excel', 'Text/CSV','PDF','JSON','dsdsd'];
cy.get('.data-sourcename').should(($els) => {
// map jquery elements to array of their innerText
const elsText = $els.toArray().map(el => el.innerText)
expect(elsText).to.deep.eq(filetypes)
})

I hope by now you must have found out the solution for this. But still, there was no selected answers yet, thought I would add one.
const Filetype = ['Access', 'Excel', 'Text/CSV','PDF','JSON','dsdsd'];
cy
.get('whatever element')
.each(($span, i) => {
expect($span.text()).to.equal(Filetype[i]);
});
$span would go through each element and .text()will get the text value of that element.

dc.js/crossfilter -> How to sort data in dc.js chart (like row) - Ascending x Descending

How to sort data in dc.js chart (like row) - Ascending x Descending
I want to reorder the chart (row/column) by specified attribute (like 'avg' -> ascending)
I'm trying to use ".top()"... but unsuccessfully
Thanks
draft below
jsfiddle -> ewr5Z/2/

You can use the ordering method:
chart.ordering(function(d){ return -d.value })
If you write a custom reduce, you can have more flexibility:
priceDimension = ndx.dimension(function(d) {return d.part_number; });
priceGroup = priceDimension.group().reduce(
function (p, v) {
++p.count;
p.sumPrice += v.price;
p.avgPrice = p.sumPrice/p.count;
return p;
},
function (p, v) {
--p.count;
p.sumPrice -= v.price;
p.avgPrice = p.sumPrice/p.count;
return p;
},
function () {
return { count:0, sumPrice:0, avgPrice};
});
....
chart.ordering(function(d){ return d.value.avgPrice});
If you want the user to be able to change the sort order, you'd need to build a sort button that changes the ordering and rerenders the chart.

Extjs4.2 filter on one column and user can use separator to match different rows

I have to filter on one column, and user can use separator to match different rows, like this: (As I couldn't post images, I have to describle the menuitme for my column)
Sort Ascending
Sort Descending
Filters => Jim|Tom
User could enter "Jim|Tom" in the Textbox to filter on the Grid.
But Generally, it seems not supported by Extjs 4.2. I found that apply multiple values for one property does not work like above.
Here is my column definition for this column 'Owner':
{
text:'Owner',
width:50,
dataIndex:'owner',
sortable:true,
filter:{
type:'string',
}
},
How could I solver this problem?
Thanks.

You would need to override string filter, something like (untested):
Ext.define('MyOverride', {
override: 'Ext.ux.grid.filter.StringFilter',
validateRecord : function (record) {
var val = record.get(this.dataIndex);
if(typeof val != 'string') {
return (this.getValue().length === 0);
}
val = val.toLowerCase();
var parts = this.getValue().toLowerCase().split('|'),
found = false;
Ext.Array.forEach(parts, function(part) {
if (val.indexOf(part) > -1) {
found = true;
}
});
return found;
}
});

How to get a jqGrid cell value when editing

How to get a jqGrid cell value when in-line editing (getcell and getRowData returns the cell content and not the actuall value of the input element).

General function to get value of cell with given row id and cell id
Create in your js code function:
function getCellValue(rowId, cellId) {
var cell = jQuery('#' + rowId + '_' + cellId);
var val = cell.val();
return val;
}
Example of use:
var clientId = getCellValue(15, 'clientId');
Dodgy, but works.

Here is an example of basic solution with a user function.
ondblClickRow: function(rowid) {
var cont = $('#grid').getCell(rowid, 'MyCol');
var val = getCellValue(cont);
}
...
function getCellValue(content) {
var k1 = content.indexOf(' value=', 0);
var k2 = content.indexOf(' name=', k1);
var val = '';
if (k1 > 0) {
val = content.substr(k1 + 7, k2 - k1 - 6);
}
return val;
}

After many hours grief I found this to be the simplest solution. Call this before fetching the row data:
$('#yourgrid').jqGrid("editCell", 0, 0, false);
It will save any current edit and will not throw if there are no rows in the grid.

As you stated, according to the jqGrid documentation for getCell and getRowData:
Do not use this method when you editing the row or cell. This will return the cell content and not the actual value of the input element
Since neither of these methods will return your data directly, you would have to use them to return the cell content itself and then parse it, perhaps using jQuery. It would be nice if a future version of jqGrid could provide a means to do some of this parsing itself, and/or provide an API to make it more straightforward. But on the other hand is this really a use case that comes up that often?
Alternatively, if you can explain your original problem in more detail there may be other options.

Try this, it will give you particular column's value
onSelectRow: function(id) {
var rowData = jQuery(this).getRowData(id);
var temp= rowData['name'];//replace name with you column
alert(temp);
}

Basically, you have to save the row before you access the cell contents.
If you do, then you get the value for the cell instead of the markup that comes when the cell is in edit mode.
jQuery.each(selectedRows, function(index, foodId) {
// save the row on the grid in 'client array', I.E. without a server post
$("#favoritesTable").saveRow(foodId, false, 'clientArray');
// longhand, get grid row based on the id
var gridRow = $("#favoritesTable").getRowData(foodId);
// reference the value from the editable cell
foodData += foodId + ":" + gridRow['ServingsConsumed'] + ',';
});

Hi， I met this problem too. Finally I solved this problem by jQuery. But the answer is related to the grid itself, not a common one. Hope it helps.
My solution like this:
var userIDContent = $("#grid").getCell(id,"userID"); // Use getCell to get the content
//alert("userID:" +userID); // you can see the content here.
//Use jQuery to create this element and then get the required value.
var userID = $(userIDContent).val(); // var userID = $(userIDContent).attr('attrName');

you can use this directly....
onCellSelect: function(rowid,iCol,cellcontent,e) {
alert(cellcontent);
}

This is my solution:
function getDataLine(grida, rowid){ //vykradeno z inineeditu a vohackovano
if(grida.lastIndexOf("#", 0) === 0){
grida = $(grida);
}else{
grida = $("#"+grida);
}
var nm, tmp={}, tmp2={}, tmp3= {}, editable, fr, cv, ind;
ind = grida.jqGrid("getInd",rowid,true);
if(ind === false) {return success;}
editable = $(ind).attr("editable");
if (editable==="1") {
var cm;
var colModel = grida.jqGrid("getGridParam","colModel") ;
$("td",ind).each(function(i) {
// cm = $('#mygrid').p.colModel[i];
cm = colModel[i];
nm = cm.name;
if ( nm != 'cb' && nm != 'subgrid' && cm.editable===true && nm != 'rn' && !$(this).hasClass('not-editable-cell')) {
switch (cm.edittype) {
case "checkbox":
var cbv = ["Yes","No"];
if(cm.editoptions ) {
cbv = cm.editoptions.value.split(":");
}
tmp[nm]= $("input",this).is(":checked") ? cbv[0] : cbv[1];
break;
case 'text':
case 'password':
case 'textarea':
case "button" :
tmp[nm]=$("input, textarea",this).val();
break;
case 'select':
if(!cm.editoptions.multiple) {
tmp[nm] = $("select option:selected",this).val();
tmp2[nm] = $("select option:selected", this).text();
} else {
var sel = $("select",this), selectedText = [];
tmp[nm] = $(sel).val();
if(tmp[nm]) { tmp[nm]= tmp[nm].join(","); } else { tmp[nm] =""; }
$("select option:selected",this).each(
function(i,selected){
selectedText[i] = $(selected).text();
}
);
tmp2[nm] = selectedText.join(",");
}
if(cm.formatter && cm.formatter == 'select') { tmp2={}; }
break;
}
}
});
}
return tmp;
}

I have a solution:
1. Using this.value to get the current editing value in the editing row.
2. Save the cell value to a hidden field when the cell lost its focus.
3. Read the hidden field when you need.
The code:
colModel="[
{ name: 'Net', index: 'Net', editable:true, editoptions: { dataEvents: [ { type: 'focusout', fn: function(e) {$('#HiddenNet').val(this.value);} }] }, editrules:{custom:true,}},
{ name: 'Tax', index: 'Tax', editable:true, editoptions: { dataEvents: [ { type: 'focus', fn: function(e) {this.value=$('#HiddenNet').val(); } }] }, editrules:{custom:true}}
]"
Good Luck

You can get it from the following way...!!
var rowId =$("#list").jqGrid('getGridParam','selrow');
var rowData = jQuery("#list").getRowData(rowId);
var colData = rowData['UserId']; // perticuler Column name of jqgrid that you want to access

In my case the contents of my cell is HTML as result of a formatter. I want the value inside anchor tag. By fetching the cell contents and then creating an element out of the html via jQuery I am able to then access the raw value by calling .text() on my newly created element.
var cellContents = grid.getCell(rowid, 'ColNameHere');
console.log($(cellContents));
//in my case logs <h3>The Value I'm After</h3>
var cellRawValue = $(cellContents).text();
console.log(cellRawValue); //outputs "The Value I'm After!"
my answer is based on #LLQ answer, but since in my case my cellContents isn't an input I needed to use .text() instead of .val() to access the raw value so I thought I'd post this in case anyone else is looking for a way to access the raw value of a formatted jqGrid cell.

its very simple write code in you grid.php and pass the value to an other page.php
in this way you can get other column cell vaue
but any one can make a like window.open(path to pass value....) in fancy box or clor box?
$custom = <<<CUSTOM
jQuery("#getselected").click(function(){
var selr = jQuery('#grid').jqGrid('getGridParam','selrow');
var kelr = jQuery('#grid').jqGrid('getCell', selr, 'stu_regno');
var belr = jQuery('#grid').jqGrid('getCell', selr, 'stu_school');
if(selr)
window.open('editcustomer.php?id='+(selr), '_Self');
else alert("No selected row");
return false;
});
CUSTOM;
$grid->setJSCode($custom);

I think an extension of this would get it for you.
retrieving-original-row-data-from-jqgrid

I think a better solution than using getCell which as you know returns some html when in edit mode is to use jquery to access the fields directly. The problem with trying to parse like you are doing is that it will only work for input fields (not things like select), and it won't work if you have done some customizations to the input fields. The following will work with inputs and select elements and is only one line of code.
ondblClickRow: function(rowid) {
var val = $('#' + rowid + '_MyCol').val();
}

I've got a rather indirect way. Your data should have an unique id.
First, setting a formatter
$.extend(true, $.fn.fmatter, {
numdata: function(cellvalue, options, rowdata){
return '<span class="numData" data-num="'+rowdata.num+'">'+rowdata.num+'</span>';
}
});
Use this formatter in ColModel. To retrieve ID (e.g. selected row)
var grid = $("#grid"),
rowId = grid.getGridPara('selrow'),
num = grid.find("#"+rowId+" span.numData").attr("data-num");
(or you can directly use .data() for latest jquery 1.4.4)

In order to get the cell value when in-line editing you need to capture this event(or another similar event, check documentation):
beforeSaveCell: function (rowid, celname, value, iRow, iCol) { }
In the value parameter you have the 'value' of the cell that was currently edited.
To get the the rest of the values in the row use getRowData()
I lost a lot of time with this, hope this helps.

My workaround is to attach an object containing orignal values to each tr element in the grid. I've used afterAddRecord callback to get my hands on the values before jqGrid throws them away and jQuery's "data" method to store them in the work.
Example:
afterInsertRow: function( rowid, rowdata, rowelem ) {
var tr = $("#"+rowid);
$(tr).data("jqgrid.record_data", rowelem);
},
“rowelem” is the array of cell values from our JSON data feed or [jsonReader] (http://www.trirand.com/jqgridwiki/doku.php?id=wiki:retrieving_data#jsonreader_as_function)
Then at any point I can fetch those attributes using:
$(tr).data(“jqgrid.record_data”).

I think that Aidan's answer is by far the best.
$('#yourgrid').jqGrid("editCell", 0, 0, false);
This commits any current edits, giving you access to the real value. I prefer it because:
You don't have to hard-code any cell references in.
It is particularly well suited to using getRowData() to get the entire grid, as it doesn't care which cell you've just been editing.
You're not trying to parse some markup generated by jqGrid which may change in future.
If the user is saving, then ending the edit session is likely the behaviour they would want anyway.

Before i was getting :
html tag of the textbox something like
but Here is the solution to get the value from that particular column, working and tested
function getValue(rowId, cellId) {
var val = $("[rowId='"+rowId+"'][name='"+cellId+"']").val();
return val;
}
var values = getValue(rowId, 'cellid');

I obtain edit value using javascript:
document.getElementById('idCell').value
I hope this info useful for someone.

I needed the original value before the formatter, so this is what I did:
{
name: 'Slot', title: false, formatter: function (cellValue, options, rowObject) {
rowObject['SlotID'] = cellValue; // <--- This saves the original ID
if (somelogic) {
return someString;
} else {
return someOtherString;
}
}
},
{ name: 'SlotID', hidden: true }
Now SlotID contains the original ID. Also, you don't need to have SlotID property on your original model.

try subscribing to afterEditCell event it will receive (rowid, cellname, value, iRow, iCol) where value is your a new value of your cell

You can use getCol to get the column values as an array then index into it by the row you are interested in.
var col = $('#grid').jqGrid('getCol', 'Sales', false);
var val = col[row];
