My assign on a table row not reflecting on the front end - javascript

I have finally filtered and retrieved the rows I want in my table and assigned it a value, it outputs to the console properly but not rendered on the web page itself.
I have retrieved my rows into a variable row and assigned it another variable
var rows = [...$(".table td")].map(e => $(e).text().trim()).filter(e => e);
console.log(rows);
for (i = 0; i < rows.length; i++) {
//I have assigned it in the line below
rows[i].text = dateArr[i];
console.log(rows[i]);
}

as you can see in your console.log(rows);
you only get a new array of string with all TD values, not a pointer on each TD with a useless complicated code
const newVals = [111,222,333];
document.querySelectorAll('#myTable td').forEach( (elmTD, idx)=>{
elmTD.textContent=newVals[idx].toString()
})
td { border:1px solid grey }
<table id="myTable">
<tr>
<td> aaa </td>
<td> bbb </td>
<td> ccc </td>
</tr>
</table>
All I can say is "forget jQuery and use javascript ES6" only because you already use arrow functions

Modify the text of table cells using js

I have a table in html and I want to alter the text inside different cells using js. My table looks like this:
<tr><td colspan="7" style="text-align:center;">Calendar evenimente tds</td></tr>
<tr>
<th>Data1</th>
<th>Data2</th>
<th>Data3</th>
<th>Data4</th>
<th>Data5</th>
<th>Data6</th>
<th>Data7</th>
</tr>
<tr>
<td id="col1row1">null</td>
<td id="col2row1">null</td>
<td id="col3row1">null</td>
<td id="col4row1">null</td>
<td id="col5row1">null</td>
<td id="col6row1">null</td>
<td id="col7row1">null</td>
</tr>
</table>
and my js script looks like this:
var j=0;
for(j=0;j<=7;j++)
document.getElementById("col"+j+"row1").innerHTML=j;
but I get this error:
Uncaught TypeError: Cannot set property 'innerHTML' of null
My question is whats the propper way of modifying the text inside a HTML table cell and what am I doing wrong?
The first iteration of your loop fails because there is no col0. Rather than iterate over IDs like this, you can simply loop over the elements by tag:
Array.from(document.getElementsByTagName('td')).forEach((td, index) => {
td.innerHTML = index
})
If you want the count to start at 1, use td.innerHTML = index + 1 instead.
loop are calling an ID that does not exist.make for loop starts with 1 instead of zero as there is no col0row1 in your html
var j;
for(j=1;j<=7;j++){
document.getElementById("col"+j+"row1").innerHTML=j;
}
As at j = 0 there is no element with id "col0row1" hence the uncaught error.
var j = 1
for(j=1;j<=7;j++){
document.getElementById("col" + j + "row1").innerHTML = j;
}

Replace old value with new value excluding the children

The initial text of A, B, C, D, and the number need to be removed in the frontend because I require it in the backend.
The HTML structure of table row is like this:
<tr ng-repeat="(key, field) in nbd_fields" ng-show="field.enable && field.published" class="ng-scope">
<td class="ng-binding">A,B,C,D: 1 - Auswahl Wunschkarte : <b class="ng-binding">Wähle eine Option</b>
</td>
<td ng-bind-html="field.price | to_trusted" class="ng-binding"></td>
</tr>
Before Input:
Current Output:
If you notice that the selected option is also not visible. Is it because of the $(window).load() ?
Required Output:
Code that I am using:
jQuery(".ng-scope td.ng-binding:first-child").text(function(i, oldVal) {
return oldVal.replace(/^[^-]+ - /,"");
});
});
How can I make it so that it does not affect the <b> tag inside?
I used the above code for the steps heading with a different selector on the same page* and it worked because it did not have any children to alter.
I had to wrap it around $(window).load() so that the changes are applied after the table is loaded. $(document).ready() did not work with it. Not sure why?
(Edit: Modified to accommodate restated requirement in comment below.)
To strip "everything up to and including the '-'" from the text of first column table cells while leaving the rest untouched:
// strip "everything up to and including the '-'"
// from table cell contents
function stripPrefix(tblCell) {
// only evaluate first td in tr
if (tblCell.previousElementSibling) {
return;
}
const tNode = tblCell.firstChild;
// ignore if table cell is empty
if (!tNode) {
return;
}
const chars = tNode.nodeValue.split('');
const iFirstDash = chars.indexOf('-');
if (iFirstDash === -1) { return; }
tNode.nodeValue = chars.slice(iFirstDash+1).join('');
}
function stripAllPrefixes() {
const tds = document.getElementsByTagName('td');
for (const td of tds) {
stripPrefix(td);
}
}
td {
border: 1px solid gray;
}
<h4>Strip "everything up to and including the '-'" from Table Cells</h4>
<table>
<tr>
<td>A,B,C,D: 1 - Auswahl Wunschkarte : <b>Wähle eine Option</b></td>
<td></td>
</tr>
<tr>
<td>B,C,D,E: 20 - A different leader : <b>should also be stripped</b></td>
<td></td>
</tr>
<tr>
<td>Oops no dash here <b>Just checking</b></td>
<td></td>
</tr>
</table>
<button onclick="stripAllPrefixes();">Strip All</button>
It does not effect the b tag, your code is working, you just need to use the right method and do the replacement to the HTML code and not the text nodes:
jQuery(".nbd-field-header label, .nbo-summary-table .ng-binding").html(function(i, oldVal) {
return oldVal.replace(/^[^-]+ - /,"");
});

datatables rows().ids() return undefined

In my datatable I set the ID attribute for rows:
'createdRow': function (row, data, dataIndex) {
$(row).attr('id', data.json.unid);
}
Under a button I want to grab the ID's:
action: function () {
var count = table
.rows({
selected: true
})
.ids();
alert("id:s" + count)
for (i = 0; i < count.length; i++) {
alert("id:" + count[i])
}
rpcService
.setIds(count
.toArray());
}
In the alert I get for the ID "undefined".
Here is what a row looks like:
<tr id="FF97C3CFC0F5FA76C12583D1003EA028" role="row" class="odd selected">
<td class=" select-checkbox"> </td>
<td>Anne Weinstein</td>
<td>ORP B</td>
<td>Anne Weinstein</td>
<td>s41660</td>
</tr>
What am I doing wrong?
You are setting IDs on the elements in the DOM, but the .ids() method is not supposed to return those.
https://datatables.net/reference/api/rows().ids()
Important This method does not read the DOM id for the tr elements, but rather gets the row id from the row's data source (location specified by rowId).
You would need to provide the IDs upfront in your data source already, so that you can match them via the rowId option, to get what datatables considers a “row id”.

Protractor - How to get all cells from one column and sum them when the Grid has id="0-0" for rows-Columns

I am validating a drill down process in the portal i am testing, for this my script is doing:
Read the value from the first row of a table and click at this value (there is a link for certain cells that perform the drill down to the detail page)
To click at this particular cell I am using it's ID:
<table id="transHistTable" class="table table-hover table-bordered table-striped dataTable no-footer" style="width: 100%" role="grid" aria-describedby="transHistTable_info">
<thead>
<tbody>
<tr role="row" class="odd">
<td id="0-0" class="ng-scope">31 Jul 2018</td>
<td id="0-1" class="ng-scope">RandomText0</td>
<td id="0-2" class="ng-scope">RandomText1</td>
<td id="0-3" class="ng-scope">EmptyValue</td>
<td id="0-4" class="ng-scope">Value I Click And Save it</td>
So for this table I am clicking directly to the row 0 column 4 since my data and my filters will always bring only one row, but then, comes my problem....
When the drill down is performed I never know how many rows I will have since it depends of user operations.
I need to perform a validation to compare the sum of all the values from the table displayed after the drill down with the value captured from table "transHistTable" row 0 column 4
This is the values I get after performing the Drill Down:
<table id="transHistDetailTable" class="table table-hover table-bordered table-striped dataTable no-footer" style="width: 100%" role="grid" aria-describedby="transHistDetailTable_info">
<thead>
</thead>
<tbody><tr role="row" class="odd">
<td id="0-0" class="ng-scope">Site</td>
<td id="0-1" class="ng-scope">Date</td>
<td id="0-2" class="ng-scope">Time</td>
<td id="0-3" class="ng-scope">I</td>
<td id="0-4" class="ng-scope">value 1</td>
<td id="0-5" class="ng-scope">value 2</td>
<td id="0-6" class="ng-scope">value 3</td>
<td id="0-7" class="ng-scope">12</td>
</tr></tbody>
</table>
So what I would like to do is reading all the rows (could be 0,1,2,3,4,5...) saving the value that is stored in Column 7 then after this is done, perform a sum and then comparing with the value I have saved from the first table.
My code is this one:
var rowstransHistDetail = element(by.id('transHistDetailTable')).all(by.tagName("tr"));
rowstransHistDetail.count().then(function(rcount){
//In case only 1 row is displayed
if (rcount < 3)
{
element(by.id('0-7')).getText().then(function(valueQty){
expect(valueQty).toEqual(600)
})
}
else
{
var tempValue
for (i=0; i < rcount; i++)
{
element(by.id(i+'-7')).getText().then(function(valueQty){
tempValue = Number(tempValue) + Number(valueQty)
})
}
expect(tempValue).toEqual(600);
}
});
But when I execute this, gives me a undefined value
Any ideas how to solve this please?
Thank you!!!!
It seems that you are incrementing a value in a loop before execution.
See here: https://stackoverflow.com/a/6867907/6331748
Should bee i++ instead of ++i in a loop.
Drop me a line if I'm wrong.
===========================
Edited:
Here's some code from my side:
var expectedCells = element.all(by.css('#transHistDetailTable tr td:nth-of-type(5)'));
var currentSum = 0;
expectedCells.each((eachCell) => {
eachCell.getText().then((cellText) => {
currentSum += Number(cellText);
});
}).then(() => {
expect(currentSum).toEqual(600);
});
Sorry, but wasn't able to test it. I only want to share a main idea and elaborate it.
expectedCells are all id=n-4 cells. We go through all elements and get text from them, change to the number type and add to current value. Aftermath we do an assertion.
It also looks that if statement is not necessarily.
Let me know how it works.
Two options for your issue:
1) using element.all().reduce()
let total = element
.all(by.css('#transHistDetailTable > tbody > tr > td:nth-child(8)'))
.reduce(function(acc, item){
return item.getText().then(function(txt) {
return acc + txt.trim() * 1;
});
}, 0);
expect(total).toEqual(600);
2) using element.all().getText() and Array.reduce
let total = element
.all(by.css('#transHistDetailTable > tbody > tr > td:nth-child(8)'))
.getText(function(txts){ //txts is a string Array
return txts.reduce(function(acc, cur){
return acc + cur * 1;
}, 0);
});
expect(total).toEqual(600);

Dynamically remove tableDatas from table

Update Code working Here
I have a table populated with teacher's disciplines that has: day of the week and it's time period, of course it also have the disciplines.
Now I need to remove those items.
Table:
<table id="prof-table">
<tbody><tr>
<th>HORÁRIO</th>
<th data-dia="mon">Monday</th>
<th data-dia="tue">Tuesday</th>
<th data-dia="wed">Wednesday</th>
<th data-dia="thu">Thursday</th>
<th data-dia="fri">Friday</th>
</tr>
<tr>
<td>08:30 ~ 10:30</td>
<td><ol><li data-id="6" data-prof="4">Calculo A</li></ol></td>
</tr>
<tr>
<td>10:30 ~ 12:30</td>
td></td><td><ol><li data-id="2" data-prof="4">Lab II</li></ol></td>
</tr>
<tr>
<td>14:30 ~ 16:30</td>
</tr>
<tr>
<td>16:30 ~ 18:30</td>
</tr>
<tr>
<td>18:30 ~ 20:30</td>
<td></td><td></td><td></td><td></td><td><ol><li data-id="5" data-prof="4">Estatistica</li></ol></td>
</tr>
<tr>
<td>20:30 ~ 21:30</td>
</tr>
<tr>
<td>21:30 ~ 23:30</td>
</tr>
</tbody></table>
What I did so far is to get the <td> from the rows but I don't know how to work with it, tried to use .each() from JQuery but I just cant do it.
Javascript:
var myRow = document.getElementById("prof-table").rows[range.index + 1];
var test = $(myRow.getElementsByTagName('td')).not(':first-child');//Skip the first td because its the time period of the discipline.
console.log(teste);
Now if you check the console.log() this is what is shown:
As you can see, there are three lines. Each line/obj has the exactly number of <td>s from the row.
What I need to do is loop through each of these lines. Also I need to reset the index for each loop.
EX: While interacting with the first line of the image, my Index goes from 0 ~ 1. Then when start the second line I need to start my index from 0 again untill 4 (because it has 5 elements td)
Tried something like:
$.each(teste, function(index, obj){
if($(obj).text() == "")
myRow.deleteCells(index);
});
But as the index doesnt "reset" for each of those lines in the picture, I get error about overflowing the row index limite. Because while the first row has only one <td> member, the last has 5, as the index is always growing ++ I get that error. And I have no idea how to work around it.
Because I don't understand you situation well, I create two function
To delete data based on "data-prof" attribute of "li" inside the "td"
To delete all data of the table.
In my oppinion, if you assign "data-prof" value to the "td" instead of "li", it'll boost performance.
Hope it's help.
Function to delete data based on "data-prof" attribute:
function resetTableData(dataProf) {
// Get cell list by data-prof
var $cellList = $("#prof-table").find("li[data-prof = " + dataProf + "]").closest("td");
$cellList.each(function(){
$(this).html(""); //Remove inner HTML of cells.
});
}
Function to delete data of all cells:
function resetTableData() {
// Get row list
var $rowList = $("#prof-table").find("tr").not(":first"); // First row is the header, don't need to select.
// Loop row list and get cell list of each
$rowList.each(function(){
// Cell list
var $cellList = $(this).find("td").not(":first"); // First column is time period, don't delete it.
// Loop cell list and delete content
$cellList.each( function() {
$(this).html(""); //Remove inner HTML of cells.
});
});
}
