Eliminate column from table using javascript - javascript

I need to automatically eliminate a column from a html table using javascript. The table is created automatically from a csv file using a framework so I can't modify it (ex. add an id, etc.). I managed to eliminate the column by adding a link to the column header, and on click it eliminates the column, but I can't find a way to do it automatically when the page loads. I'm new to javascript so please try to explain it for dummies.
function closestByTagName(el, tagName) {
while (el.tagName != tagName) {
el = el.parentNode;
if (!el) {
return null;
}
}
return el;
}
function delColumn(link) {
var idx = 2,
table = closestByTagName(link, "TABLE"),
rowCount = table.rows.length;
for (var i = 0; i < rowCount; i++) {
table.rows[i].deleteCell(idx);
}
return false;
}
window.onload = function() {
var th = document.querySelectorAll("th");
th[2].innerHTML += ' X';
}
<div class="table">
<table class="inline">
<tr class="row0">
<th class="col0">FullName</th>
<th class="col1">Country</th>
<th class="col2">Position</th>
<th class="col3">CellPhone</th>
<th class="col4">Email</th>
</tr>
<tr class="row1">
<td class="col0">magnus</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">22</td>
<td class="col4">magnus.gaylord#example.com</td>
</tr>
<tr class="row2">
<td class="col0">Phoebe Feest</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">23</td>
<td class="col4">ylittel#example.net</td>
</tr>
<tr class="row3">
<td class="col0">Prof. Tad Johnston</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">24</td>
<td class="col4">srau#example.org</td>
</tr>
<tr class="row4">
<td class="col0">Annabelle Ortiz</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">25</td>
<td class="col4">damore.walker#example.org</td>
</tr>
<tr class="row5">
<td class="col0">Mrs. Adella Schiller IV</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">26</td>
<td class="col4">jadyn.dibbert#example.com</td>
</tr>
</table>
</div>
The above code works but I have to press the x on the position column for it to be eliminated and I need it to happen automatically. In other words I don't want to use the code href="#" onclick="return delColumn(this)" but have it happen on load.


Since all your columns have a particular class, maybe one possible solution using ES6 is to use:
document.querySelectorAll(".col2").forEach(col => col.remove());
Or with a standard approach:
var cols = document.querySelectorAll(".col2");
for (var i = 0; i < cols.length; i++)
{
cols[i].remove();
}
Example:
window.onload = function()
{
var cols = document.querySelectorAll(".col2");
for (var i = 0; i < cols.length; i++)
{
cols[i].remove();
}
// Or with ES6:
//document.querySelectorAll(".col2").forEach(col => col.remove());
}

Shidersz's answer is fine, but it's also worth noting that you could do with with a single CSS rule instead of JavaScript:
.col2 {
display: none;
}
<div class="table">
<table class="inline">
<tr class="row0">
<th class="col0">FullName</th>
<th class="col1">Country</th>
<th class="col2">Position</th>
<th class="col3">CellPhone</th>
<th class="col4">Email</th>
</tr>
<tr class="row1">
<td class="col0">magnus</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">22</td>
<td class="col4">magnus.gaylord#example.com</td>
</tr>
<tr class="row2">
<td class="col0">Phoebe Feest</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">23</td>
<td class="col4">ylittel#example.net</td>
</tr>
<tr class="row3">
<td class="col0">Prof. Tad Johnston</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">24</td>
<td class="col4">srau#example.org</td>
</tr>
<tr class="row4">
<td class="col0">Annabelle Ortiz</td>
<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>
<td class="col3">25</td>
<td class="col4">damore.walker#example.org</td>
</tr>
<tr class="row5">
<td class="col0">Mrs. Adella Schiller IV</td>

Add dynamically rowspan with Javascript/ jQuery

I am trying to add dynamically rowspan to my table, I am totally new in the programming world so I am still learning. This is my table::
<table border="1">
<thead>
<tr>
<th class="text-center">Building</th>
<th class="text-center">Student ID</th>
<th class="text-center">Student Name</th>
<th class="text-center">Payable</th>
<th class="text-center">Paid Amount</th>
<th class="text-center">Due</th>
<th class="text-center">Active</th>
</tr>
</thead>
<tbody>
<tr>
<td class="build-name" rowspan="3"><b>School 1</b></td>
<td align="center">151-15-4366</td>
<td align="center">Lorem Name</td>
<td align="center">13000</td>
<td align="center">10500</td>
<td align="center">2500</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-4852</td>
<td align="center">Lorem Name</td>
<td align="center">13000</td>
<td align="center">3000</td>
<td align="center">10000</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-5355</td>
<td align="center">Lorem Name</td>
<td align="center">18000</td>
<td align="center">3000</td>
<td align="center">15000</td>
<td align="center">True</td>
</tr>
<tr>
<td class="build-name" rowspan="2"><b>School 2</b></td>
<td align="center">151-15-4841</td>
<td align="center">Lorem Name</td>
<td align="center">13000</td>
<td align="center">10500</td>
<td align="center">2500</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-4930</td>
<td align="center">Lorem Name</td>
<td align="center">18000</td>
<td align="center">33000</td>
<td align="center">-15000</td>
<td align="center">True</td>
</tr>
</tbody>
</table>
So if I add a new student to the table, I need to adjust rowspan so I was wondering if there is a way to add that automatically when I add a new student:
For example currently, if I add a new student my table is totally messed up:
<table border="1">
<thead>
<tr>
<th class="text-center">Building</th>
<th class="text-center">Student ID</th>
<th class="text-center">Student Name</th>
<th class="text-center">Payable</th>
<th class="text-center">Paid Amount</th>
<th class="text-center">Due</th>
<th class="text-center">Active</th>
</tr>
</thead>
<tbody>
<tr>
<td class="build-name" rowspan="3"><b>Shool 1</b></td>
<td align="center">151-15-4366</td>
<td align="center">Lorem Name</td>
<td align="center">13000</td>
<td align="center">10500</td>
<td align="center">2500</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-4852</td>
<td align="center">Lorem Name</td>
<td align="center">13000</td>
<td align="center">3000</td>
<td align="center">10000</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-5355</td>
<td align="center">Lorem Name</td>
<td align="center">18000</td>
<td align="center">3000</td>
<td align="center">15000</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-5355</td>
<td align="center">Lorem Name</td>
<td align="center">18000</td>
<td align="center">3000</td>
<td align="center">15000</td>
<td align="center">True</td>
</tr>
<tr>
<td class="build-name" rowspan="2"><b>School 2</b></td>
<td align="center">151-15-4841</td>
<td align="center">Lorem Name</td>
<td align="center">13000</td>
<td align="center">10500</td>
<td align="center">2500</td>
<td align="center">True</td>
</tr>
<tr>
<td align="center">151-15-4930</td>
<td align="center">Lorem Name</td>
<td align="center">18000</td>
<td align="center">33000</td>
<td align="center">-15000</td>
<td align="center">True</td>
</tr>
</tbody>

I know that I can adjust rowspan but I want to do this via Javascript/jQuery, can anybody try to help me with this?

This works
Add a tbody per building
Calculate the rows in each building
Plain JS
document.querySelectorAll("table tbody")
.forEach(tb => tb.querySelector(".build-name")
.setAttribute("rowspan",tb.querySelectorAll("tr").length))
document.querySelectorAll("table tbody")
.forEach(tb => tb.querySelector(".build-name")
.setAttribute("rowspan",tb.querySelectorAll("tr").length))

I want to save every block with id on localstorage. I know I can use localStorage.setItem("p1d1", $('#p1d1').text()); to save these, but is there a better way to save all of these blocks without going like
localStorage.setItem("p1d1", $('#p1d1').text());
localStorage.setItem("p2d1", $('#p2d1').text());
localStorage.setItem("p3d1", $('#p3d1').text());
through the whole thing? I need to call each of them by their id later on.
Thank you.

You can use document.querySelectorAll('td[id^=p]') to select all the td that has id that startsWith p.
const tds = Array.from(document.querySelectorAll('td[id^=p]'));
tds.forEach(td => {
const id = td.id;
const text = td.innerText;
console.log(id, text);
})

Personally I would store it in one key instead of tons of keys. Simple reduce statement can let you gather all of the data.
var cells = document.querySelectorAll('td[id^="p"]')
function save() {
const data = Array.from(cells).reduce(function (o, td) {
o[td.id] = td.innerHTML;
return o
}, {})
console.log(data)
//window.localStorage("data", JSON.stringify(data))
}
function loadData () {
var data = window.localStorage("data")
if (data) {
var obj = JSON.parse(data)
Object.entries(obj).forEach( function (entry) {
document.getElementById(entry[0]).innerHTML = entry[1]
})
}
}
save()

I would recommend adding a class to each cell:
<tr>
<th>Period 1</th>
<td id="p1d1" tabindex=1 class="periodCell"></td>
<td id="p1d2" tabindex=2 class="periodCell"></td>
<td id="p1d3" tabindex=3 class="periodCell"></td>
<td id="p1d4" tabindex=4 class="periodCell"></td>
<td id="p1d5" tabindex=5 class="periodCell"></td>
<td id="p1d6" tabindex=6 class="periodCell"></td>
</tr>
Then doing something along the lines of the following:
$('.periodCell').each(function(index, elem)
{
localStorage.setItem(elem.id, elem.textContent);
});
you could do some other things with the selector so that you're not needing to add the class to every cell, but this is the most basic option...
another is regex on the cell ids... but that would be pretty painful

How can I use special characters in angular directives attributes?

I would like to use strings including german characters (Ä, Ö, Ü) in attributes of a custom angularJS directive.
For example:
<my-custom-directive my-label="Lärm" />
Another example is the ui.bootstrap.tabs directive:
<tabset>
<tab heading="Lärm"> content ... </tab>
<tab heading="Second Heading"> content ... </tab>
</tabset>
This results in a tab with heading "L�rm". Any ideas?

Usually in a good editor you can change the document encoding type, the document is saved in. try to set it to iso-8859-1/utf-8 and save/upload again.
Next bet would be to change the encoding of the html-output with
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
Umlauts often is trial & error...

Use escape characters for javascript.

How can I sum total after every category?
Thanks a lot

Here is a FIDDLE that does most of what you want.
I just saw your comment about the totals after every tbody...I'll have to work on it a bit more. Still doable.
JS
var totrow = 0, totcol=0; //setting totalsforrow and totalsforcolumns variables to zero
$('.numrow').each( function(){ //for each of the rows with class='numrow'
for(var n=1; n<5; n++) //do a loop four times for the right column totals
{
totrow = totrow + parseInt( $(this).children("td:eq("+ n +")").text() );
} //grab the values of each of the four tds and add them together
$( $(this).children('td:eq(5)') ).html(totrow); //put the summed value in the 'total' td
totrow = 0; // reset the value for the next "each .numrow"
});
for(var m = 1; m < 5; m++) //for loop for four column totals
{
$('.numrow').each( function(){ // for each of the rows with class .numrow
totcol = totcol + parseInt($(this).children("td:eq("+ m +")").text() );//add up values
console.log(totcol); // just a view of the totcol printed to the console log
});
$( "#sum_table tr:eq(11) td:eq(" + m + ")" ).html( 'Col total: ' + totcol );//put total at bottom of column
totcol = 0; //reset total to get read for the next loop
}
Edit: Here's the update FIDDLE. It's brute-force, inelegant, but it works.

if we click on following button then table 2 should get highlighted with any non matching data with table2.
<div style="align:right"><input type="submit" value="Compare IVR & TNS" /></div>

I wrote a quick function that should work as long as the number of rows is always the same and the user can't remove a row. in which case you should add id's to the rows and compare the rows by id or key.
function compareTables(t1, t2){
var t2rows = t2.find('tbody > tr');
t1.find('tbody > tr').each(function(index){
var t1row = $(this);
var t2row = $(t2rows[index]);
var t2tds = t2row.find('td');
t1row.find('td').each(function(index){
if($(this).text().trim() != $(t2tds[index]).text().trim() ){
console.log('difference: table1:('+$(this).text()+') table2:('+$(t2tds[index]).text()+')');
//set row in error
return;
}
});
});
}
