Drawing arrows above HTML - javascript

I have an html table and I want to draw an arrow from one cell to an other cell. For example like this:
How could this be done?
Example HTML:
<html>
<body>
<table>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td id="end">9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
<tr><td id="start">0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><tr>
</body>
</html>
If you resize the browser, the arrow should stay on the (new) start/end position.


With a bit of JavasSript and CSS you can achieve this without canvas or SVG. Here is an example:
function getPosition(el) {
return {
x: el.offsetLeft + el.offsetWidth / 2,
y: el.offsetTop + el.offsetHeight / 2
};
}
function getDistance(a, b) {
const from = getPosition(a);
const to = getPosition(b);
return {
//https://stackoverflow.com/a/17628488/529024
distance: Math.hypot(from.x - to.x, from.y - to.y),
angle: Math.atan2(to.x - from.x, from.y - to.y) * 180 / Math.PI,
position: {
start: from,
end: to
}
}
}
function init(){
// Get values and elements then set style
const values = getDistance(
document.getElementById("start"),
document.getElementById("end")
);
let wrapper = document.getElementById('wrapper');
let arrow = document.getElementById('arrow');
let bottom = wrapper.offsetHeight - values.position.start.y;
arrow.style.height = values.distance + "px";
arrow.style.transform = `rotate(${values.angle}deg)`;
arrow.style.bottom = bottom + "px";
arrow.style.left = values.position.start.x + "px";
}
init();
window.addEventListener('resize', function(){
init();
});
#wrapper {
position: relative;
left: 50px;
top: 100px;
}
#arrow {
position: absolute;
width: 2px;
background-color: red;
transform-origin: bottom center;
}
#arrow::before {
position: absolute;
height: 0px;
width: 0px;
border: 6px solid transparent;
border-bottom: 8px solid red;
content: "";
bottom: 100%;
left: 50%;
transform: translateX(-50%);
}

You can use my solution not complete draw arrow yet,
let create a canvas and draw a line from two points, based on calculate of start and end point.

This is how I would do it:
The svg element uses the size of the table for the viewBox value.
You are calculating the size and the position of the cells you need to correlate and use this position to draw the line. A marker is used for the tip of the arrow.
Please resize the window:
let cells = Array.from(document.querySelectorAll("td"));
// index of cells to be correlated
let n1 = 90;
let n2 = 9;
// a function to draw the arrow
function drawArrow(){
//get the size of the table
let size = theTable.getBoundingClientRect();
//set the viewBox attribute for the svg element
theSVG.setAttributeNS(null, "viewBox", `0 0 ${size.width} ${size.height}`)
//get the size and the position of the cells
let c1 = cells[n1].getBoundingClientRect();
let c2 = cells[n2].getBoundingClientRect();
//set the x1, y1, x2,y2 attributes of the line
theLine.setAttributeNS(null,"x1",`${c1.left + c1.width/2}`);
theLine.setAttributeNS(null,"y1",`${c1.top + c1.height/2}`);
theLine.setAttributeNS(null,"x2",`${c2.left + c2.width/2}`);
theLine.setAttributeNS(null,"y2",`${c2.top + c1.height/2}`);
}
drawArrow()
window.setTimeout(function() {
drawArrow()
window.addEventListener('resize', drawArrow, false);
}, 15);
body {
margin: 0;

UPDATE:
Since someone commented that on resize the arrow is losing it's position I am adding a gif:


Javascript solution:
drawLine();
function drawLine () {
var table = document.getElementById('my-table')
var startElement = document.getElementById('start')
var endElement = document.getElementById('end')
let arrowRadius = 10;
let xStart = null;
let xEnd = null;
if (startElement.offsetLeft > endElement.offsetLeft) {
xStart = startElement.offsetLeft + (arrowRadius/2);//to add padding just add more wherever theres this pattern
xEnd = endElement.offsetLeft + endElement.offsetWidth / 2;
} else if (startElement.offsetLeft < endElement.offsetLeft) {
xStart = startElement.offsetLeft + startElement.offsetWidth - (arrowRadius/2);
xEnd = endElement.offsetLeft;
} else {
xStart = startElement.offsetLeft + startElement.offsetWidth / 2;
xEnd = endElement.offsetLeft + endElement.offsetWidth / 2;
}
let yStart = null;
let yEnd = null;
if (startElement.offsetTop > endElement.offsetTop) {
yStart = startElement.offsetTop + (arrowRadius/2);
yEnd = endElement.offsetTop + endElement.offsetHeight + (arrowRadius/2);
} else if (startElement.offsetTop < endElement.offsetTop) {
yStart = startElement.offsetTop + startElement.offsetHeight - (arrowRadius/2);
yEnd = endElement.offsetTop - (arrowRadius/2);
} else {
yStart = startElement.offsetTop + startElement.offsetHeight / 2;
yEnd = endElement.offsetTop + endElement.offsetHeight / 2;
}
let coordBegin = {
x: xStart,
y: yStart
};
let coordEnd = {
x: xEnd,
y: yEnd
};
var canvas = document.createElement('canvas')
canvas.width = table.offsetWidth
canvas.height = table.offsetHeight
canvas.style.position = 'absolute'
var ctx = canvas.getContext('2d')
drawArrowhead(ctx, coordBegin, coordEnd, arrowRadius);

var x_center = to.x;
var y_center = to.y;

You can use an SVG element and css styles for absolute position overlaying your table. And get the start and end point by JavaScript DOM API like getBoundingClientRect()
Here is a demo. (Made with Angular, but you can use it everywhere. Pure JavaScript example see below.)
const startElement = document.querySelector('#start');
const endElement = document.querySelector('#end');
const startRect = startElement.getBoundingClientRect();
const endRect = endElement.getBoundingClientRect();
const startX = startRect.right;
const startY = startRect.top;
const endX = endRect.left;
const endY = endRect.bottom;
You can change the start and end dynamically. You only have to reinvoke the method to get the positions. Note that I use left, top, right, button to place the arrow on the edge of the element. You could compute the center point or the edge by comparing the both positions.
And you have to place the svg over the table. You can do this by set css position: absolute; left: 0; top: 0. But note, that your parent should also have the position attribute. e.g. position: relative.
Update: Here is a pure JavaScript demo. Click on the left to view all files and select index.js to view the JS stuff. (like in VS Code).
Complete code:
<table style="position: absolute; left: 0; top: 0;">
<tr>

Just copy the code above in a new empty html file and run it in your browser.
Btw. You can also do this with a canvas. (alternative for svg)


You need to put the table in a div and give a property, position: relative
Then write HTML for the arrow (use an image if you want to) and give it a property of absolute and then style it as you want using, top, left, right..
Read more about position properties here https://www.w3schools.com/css/css_positioning.asp

Alternating color rows based on values of cells

I'd like to have a table with alternating colors of rows but rows with the same value should have unitary background color. Can I achieve such an effect with CSS?
Example:

JQuery
(feel free to simplify and edit this)
$(function() {
let elems = $('tr:not(".head")');
let count = 0;
for (let i=0; i<elems.length; i++) {
let el = $(elems[i]),
prev = $(elems[i-1]);
let isEven = (count % 2 == 0);
if (isEven) {
el.css('background', 'red');
} else {
el.css('background', 'yellow');
}
if (el.text() == prev.text()) {
let clr = prev.css('background');
el.css('background', clr);
} else {
count++;
}
}

Without the styling, I can't see if it exactly matches what you are trying to achieve, but you can check the styling later.
The basic structure of the thead tag should be something like:
<thead>
<tr>
<th colspan=9>This should display on print</th>
</tr>
<tr>
<th>ID Number</th>
<th>Name</th>
<th>Barangay</th>
<th>Sex</th>
<th>Sector</th>
<th>Amount</th>
<th>Signature/thumb</th>
<th >ID </th>
<th>Date Received</th>
</tr>
</thead>
<tfoot>
<tr>
<td colspan=9>Text for the footer goes here</td>
</tr>
</tfoot>
In your table you have 9 columns, so the title th tag needs to span all 9. This is done by adding colspan=9 into the th element itself.
The footer should be added in a similar way. Note that tfoot MUST be entered immediately after thead and BEFORE any tbody tags
(updated to include tfoot)

Fixed row inside a horizontally scrollable table

I have a very long table with horizontal scrolling. Is it possible to implement a fixed row inside this table without horizontal scroll.
<div class="container" style="width:500px;height:100px;overflow:auto;position:relative;">
<table style="width:1500px;">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
</tr>
<tr style="width:500px;height:200px;left:0;right:0">
<td colspan="7" style="width:500px;">
<div id="noscroll" style="display: inline-block;">A row unaffected by horizontal scroll</div>
</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
</tr>
</table>
</div>
EDIT: What if I need two cell in the fixed row?
<tr class="fixed-row">
<td colspan="3">
A row unaffected by
</td>
<td colspan="3">
horizontal scroll
</td>
</tr>
https://jsfiddle.net/7nz6ys2m/2/

Try the following:
<div class="container" style="width:500px;overflow:auto;position:relative;">
<table style="width:1500px;">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
</tr>
<tr style="width:500px;left:0;right:0">
<td colspan="7" style="width:500px;height:22px;position: relative;">
<div id="noscroll" style="display: inline-block;position: fixed;transform: translateY(-50%);">
A row unaffected by horizontal scroll
</div>
</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
</tr>
</table>
</div>
What I did:
Give the noscroll-div position:fixed; and reset its position with transform. Then I set the height of its parent td to a fixed height of 22px (the other td are all 22px) and set its position to relative.
In case you need multiple td in the fixed row, I would rather take multiple div inside one td, and float them left. see this:
<div class="container" style="width:500px;overflow:auto;position:relative;">
<table style="width:1500px;">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
</tr>
<tr style="width:500px;left:0;right:0;height:22px;position: relative;">
<td style="position: fixed;" colspan="7">
<div style="width:250px;float: left;">
test1
</div>
<div style="width:250px;float:left;">
test2
</div>
</div>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
</tr>
</table>
</div>

With a little bit of jQuery, we can get the behavior with safe vertical scrolling.
<div class="container" style="width:500px;height:300px;overflow:auto;">
<table style="width:1500px;height:500px;">
<tr>
<td>1</td>
<td>2</td>

<td>4</td>
<td>5</td>
<td>6</td>

<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr style="">
<td colspan="6" style="">
<div class="fixed-row">A row unaffected by horizontal scroll</div>
</td>
</tr>
<tr>
<td>1</td>

How to select 5 successive rows

I got a table with several trs. I want to select 5 trs in a row and give them a background color, then take the next 5 trs and give them another background color - like even and odd, but with 5 elements as a block.
This is what I have tried
var trs = $('table.small-only tr');
for (var i = 1; i < trs.length; i += 5) {
if (i%2 == 0){
// select even blocks
}else {
// select odd blocks
}
}
This doesn't work though.
How can I select blocks containing 5 trs and give the even and odd blocks different background colors in a proper way?
I found a work around:
for (var i = 1; i < trs.length; i += 5) {
trs.slice(i, i + 5).wrapAll("<div></div>");
}
and
div {
&:nth-of-type(odd) {
background: #f2f2f2 !important;
}
}
But clearly putting divs around trs in a table isn't a good way.

Here is my example:
function getRandomColor() {
var letters = '0123456789ABCDEF';
var color = '#';
for (var i = 0; i < 6; i++ ) {
color += letters[Math.floor(Math.random() * 16)];
}
return color;
}
var my_table_rows= $('.my-table tr');
var color;
for (var i = 0; i < my_table_rows.length; i++){
if (i % 5 === 0) color = getRandomColor();
my_table_rows.eq(i).css('background', color);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="my-table">
<tr><td>1</td></tr>
<tr><td>2</td></tr>
<tr><td>3</td></tr>
<tr><td>4</td></tr>
<tr><td>5</td></tr>
<tr><td>6</td></tr>
<tr><td>7</td></tr>
<tr><td>8</td></tr>
<tr><td>9</td></tr>
<tr><td>10</td></tr>
<tr><td>11</td></tr>
<tr><td>12</td></tr>
<tr><td>13</td></tr>
<tr><td>14</td></tr>
<tr><td>15</td></tr>
<tr><td>16</td></tr>
<tr><td>17</td></tr>
</table>

To achieve this you can loop through the tr elements in the table stepping over the number of rows you want per group. You can then use slice() to retrieve the set number of rows before calling addClass() on them. Try this:
var groupSize = 5;
var classes = ['group1', 'group2'];
var $rows = $("table.small-only tr");
for(var i = 0; i < $rows.length; i += groupSize) {
$rows.slice(i, i + groupSize).addClass(classes[i / groupSize % classes.length]);
}
.group1 { background-color: #C00; }
.group2 { background-color: #0C0; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="small-only">
<tr><td>1</td></tr>
<tr><td>2</td></tr>
<tr><td>3</td></tr>
<tr><td>4</td></tr>
<tr><td>5</td></tr>
<tr><td>6</td></tr>
<tr><td>7</td></tr>
<tr><td>8</td></tr>
<tr><td>9</td></tr>
<tr><td>10</td></tr>
<tr><td>11</td></tr>
<tr><td>12</td></tr>
</table>

but clearly putting divs around trs in a table isnt a good way
No, it is invalid html. However you can use <tbody> instead of <div>
A table can have any number of <tbody> elements

You can do like that way
HTML
<table class="table">
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
<tr><td>test</td></tr>
</table>
Jquery
$(function(){
var limit = 5;
var arr = ['red','green','yellow','blue','orange'];
$('.table tr').each(function(i,e){
var ind = parseInt((i/limit));
$(this).css('background',arr[ind]);
})
})

You can also use CSS selector :nth-child(xn) and :not():
tr:nth-child(10n - 5)~ tr:not(:nth-child(10n + 1)):not(:nth-child(10n + 2)):not(:nth-child(10n + 3)):not(:nth-child(10n + 4)):not(:nth-child(10n + 5)) {background-color:gray}
tr {
background: turquoise;
counter-increment: trs;
}
tr:nth-child(10n - 5)~ tr:not(:nth-child(10n + 1)):not(:nth-child(10n + 2)):not(:nth-child(10n + 3)):not(:nth-child(10n + 4)):not(:nth-child(10n + 5)) {
background: tomato
}
/* check row numbers */
tr:before {
content: counter(trs);
display: table-cell;
padding: 0.25em;
border: solid;
background: yellow;
}
tr:nth-child(odd):before {
background: gray;
}
td {
padding: 0.25em;
border: solid;
}

Pure CSS/HTML/Javascript 2D Scrollable table with fixed column and header

I have a large table which might need to scroll both horizontally and vertically. I have seen lots of solutions for this but haven't found one that works that doesn't rely on jscript or similar. It seems like it should be doable but I've come up with problems. I think I can get the header row ok, but I am having trouble with the fixed column. I can't seem to get my body to extend beyond the viewport and my code is rendering very differently on IE8 and Firefox.
Can anyone give me any guidance?
<html>
<head>
<script type="text/javascript">
function windowwidth(){
var myWidth = 0;
if( typeof( window.innerWidth ) == 'number' ) {
myWidth = window.innerWidth;
} else if( document.documentElement && ( document.documentElement.clientWidth ||document.documentElement.clientHeight ) ) {
myWidth = document.documentElement.clientWidth;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
myWidth = document.body.clientWidth;
}
return myWidth ;
}
function windowheight(){
var myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth ||document.documentElement.clientHeight ) ) {
myHeight = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
myHeight = document.body.clientHeight;
}
return myHeight ;
}

I worked on it further though and came up with this solution. It works pretty well and is even pretty flexible. I think it's the best solution I've seen. Please let me know if you know of something better or know of a way to improve it.
The only thing I've found impossible to fix is the vertical-align which has to be top. Does anyone know of a decent, simple solution that makes IE8 respect vertical-align center for a td with a height?
Here is the demo: http://maymay.de/demos/table.html
