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

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">True</td>

<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>

<td align="center">10500</td>
<td align="center">2500</td>
<td align="center">True</td>

<td align="center">151-15-4930</td>
<td align="center">Lorem Name</td>
<td align="center">18000</td>
<td align="center">33000</td>

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

document.querySelectorAll("table tbody")

Eliminate column from table using 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">

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 class="row1">

<td class="col1">Guatemala</td>
<td class="col2">Lacayo</td>

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.

Filling a table with array of Strings

I am trying to fill a table with values from an array. How can I fill the second column (AKA the "Correct Answer" column) with the Strings defined in the stock array? I am trying to correctly fill that column with the "Correct Answers" and the "Your Answer" column with an array of String that the user gives. (Not shown, in another class).
var stock = new Array()
stock[0] = new Array("The")
stock[1] = new Array("of")
stock[2] = new Array("and")
stock[3] = new Array("a")
stock[4] = new Array("to")
stock[5] = new Array("in")
stock[6] = new Array("is")
stock[7] = new Array("you")
stock[8] = new Array("that")
stock[9] = new Array("it")
stock[10] = new Array("he")
stock[11] = new Array("for")
stock[12] = new Array("was")
stock[13] = new Array("on")
stock[14] = new Array("are")

You can use querySelectorAll() to grab each table cell and then fill it while you iterate over them:
var stock = [["The"], ["of"], ["and"], ["a"], ["to"],
["in"], ["is"], ["you"], ["that"], ["it"],
["he"], ["for"], ["was"], ["on"], ["are"]];
var nodes = document.querySelectorAll('td.tg-031e:nth-child(2)');
[].forEach.call(nodes, function(node, index) {
node.innerText = stock[index][0];
});
.tg {border-collapse:collapse;border-spacing:0;}
.tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;}

you can use document.write method and fill each rows of that column individually. or you can give id to each row of that column 1,2... and then iterate in the script from 1 to the maximum Id and use document.getElementById(idNumber).innerHTMl method to set the given values.
Here is one example for you
<p id="1"></p>
<p id="2"></p>
<p id="3"></p>
<script>
for(i=1;i<=3;i++)
{
document.getElementById(i).innerHTMl=yourDataOverHere
}
</script>

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;
}
});
});
}
