javascript table alignment

I'm trying to align the tables' titles with the items form another page using a js loop, tried padding, spacing etc.. nothing worked!
$(document).ready(function() {
let products = ['bread', 'sweets', 'coffee'];
$('#prepurchased').html('<table class ="thead"id="items" ><tr><th>Item</th><th> </th><th>Price</th><th>quantity</th></tr>');
products.forEach(function(i) {
let p = sessionStorage.getItem(i);
if (p !== null) {
p = JSON.parse(p);
$('#prepurchased').append('<table id="items" class="cart" align="center"><tr><td>' + i + '</td>' + '<td>$' + p.price + '</td>' + '<td>' + p.quantity + '</td></tr>');
$('#purchase').css('display', 'block');
}
});
});

All your data should be in the same <table>. That's what tables are for. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/table
Also:
It seems you wanted to separate <thead> and <tbody>
I removed an empty <th> that was confusing
You made your "purchase" button visible at each data row, which doesn't seem useful
if (p !== null) doesn't prevent rendering the JSON when p is undefined. Just write if (p) instead
$(document).ready(...) is longer to write. You may use the shorthand $(...)
I had to fake sessionStorage for the snippet to run live.
$(_e => {
const products = ['bread', 'sweets', 'coffee'];
$('#prepurchased').html('<table class="cart" id="items"><thead><tr><th>Item</th><th>Price</th><th>quantity</th></tr></thead><tbody></tbody></table>');
products.forEach(i => {
//let p = sessionStorage.getItem(i); //TODO: restore this
let p = fakeStorage[i]; //TODO: remove this
if (p) {
p = JSON.parse(p);
$('#prepurchased .cart tbody').append('<tr><td>' + i + '</td>' + '<td>$' + p.price + '</td>' + '<td>' + p.quantity + '</td></tr>');
}
});
if (products.length)
$('#purchase').css('display', 'block');
});
//TODO: remove, for testing only (sessionStorage rises error with cross-domain js)
fakeStorage = {
'bread': '{"price": 21.2, "quantity": 25}',
'coffee': '{"price": 34.55, "quantity": 32}',
/*'sweets': '{"price": 6.12, "quantity": 1}',*/

Jquery Toggle Content between two specific words in HTML

I have the following Javascript code to toggle content between -a- & -ea-.
When this runs, I have a "View answer" link in my HTML.
Now, I want to behavior like: between -example- & -endexample- , I should have a "View example" link, between -sample- & -endsample-, I should have a "View Sample" link and so on.
The fiddle https://jsfiddle.net/eoc74009/6/
$(document).ready(funciton(){
initToggleContent();
});
initToggleContent = function(){
var p_content = $(".content").html();
p_content = p_content.replace(new RegExp("-a-","g"),"<div class='hidden toggle-content'>")
p_content = p_content.replace(new RegExp("-ea-","g"),"</div><hr>")
$(".content").html(p_content);
$("<a class='toggle-button'>View Answer</a>").insertBefore(".toggle-content");
$(document).on('click',".toggle-button",function(){
$(this).next(".toggle-content").toggleClass("hidden");
if($(this).html()==="View Answer"){
$(this).html("Hide Answer");
}
else{
$(this).html("View Answer");
}
});
}

You can use this code:
p_content = p_content.replace(/-([^\-]+)-([\s\S]*)-end\1-/gm, function(_, name, content) {
return '<a class="toggle-button" data-name="' + name +
'">View ' + name + '</a>' +
'<span class="hidden toggle-content">' +
content + '</span><hr>';
});
span instead of div because div can't be inside p tag.
Regex explanation:
-([^\-]+)- will match dash, any number of not dashes and a dash
([\s\S]*) will match anything including newline characters
-end\1- will match dash end and prevouisly matched name
parentesis are used as capturing group so you can reference them in replace.
And modifed click handler:
$(document).on('click',".toggle-button",function(){
$(this).next(".toggle-content").toggleClass("hidden");
var name = $(this).data('name');
if($(this).html()==="View " + name){
$(this).html("Hide " + name);
}
else{
$(this).html("View " + name);
}
});
JSFIDDLE

I went a little silly on this and kept iterating an the answer to come up with a more frameworky solution, this allows you to create your own html snippets that look kind of like jsx, and rely's on css checkboxes to toggle the content rather than binding js which can get cumbersome if not managed properly.

apply diffrent css for text separated by comma inside <div>

i am trying to change color for text which are separated by comma(','). i cant use any other tag to separate these. is that possible by jQuery or by css?
<div data-value="ABCD,XYZ" style="padding-left: 12px; padding-right: 12px;">ABCD,XYZ</div>
<div data-value="ABCD,XYZ" style="padding-left: 12px; padding-right: 12px;">cdE,hhhh</div>

Created a fiddle for you
var colorArr = ['red', 'green'];
$( "[data-value='ABCD,XYZ']" ).each ( function(){
var valueArr = $( this ).html().split( "," );
console.log( valueArr );
for (var counter = 0; counter < valueArr.length; counter++ )
{
valueArr[ counter ] = "<span style='color:" + colorArr[ counter ] + "'>" + valueArr[ counter ] + "</span>";
}
console.log( valueArr );
$( this ).html( valueArr.join("") );
} );

Im not sure if you are referring to the innerHTML or the tag's value.. either way. I was not able to test this due to browser issues.
$('div').each(function(){
var textArray = $(this).html().split(',');
var html = '';
for(var i = 0; i < textArray.length; i++) {
html += '<span style="color: #12345' + i + '">' + textArray[i] + '</span>';
}
$(this).html(html);
}

This is what I would do:
$("[data-value]").each(function(){
var words = $(this).text().split(",");
$(this).text("");
for(var i=0; i< words.length; i++){
var r = Math.floor((Math.random() * 255) + 1);
var g = Math.floor((Math.random() * 255) + 1);
var b = Math.floor((Math.random() * 255) + 1);
$(this).append("<span style='color:rgb("+r+","+g+","+b+")'>"+words[i]+ ((i< words.length-1) ? ",":"")+"</span>");
}
});
Here is the JSFiddle demo
The code randomly generates colors and sets a different color for each word.

You can use
:contains() css3 selector

Check this out
$(document).ready(function(){
$('div').each(function(){
var text = $(this).text();
var array = text.split(',');
var html = array[0] + ',<span style="color:red">' + array[1] + '</span>';
$(this).html(html);
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div data-value="ABCD,XYZ" style="padding-left: 12px; padding-right: 12px;">ABCD,XYZ</div>
<div data-value="ABCD,XYZ" style="padding-left: 12px; padding-right: 12px;">cdE,hhhh</div>

Since you are using attr data use .data() to find your elements
$('div').data('value','ABCD,XYZ').each(function(i,vi){
var arrVi = vi.innerText.split(',');
var html = '';
arrVi.forEach(function(vj,j){
html += '<span style="color: green">' + vj + '</span>';
});
vi.innerHTML= html;
})
Change the code to the ways it suits you better.

If you can't change the html code at all you can use :before and :after pseudo selectors.
Split the text by ,.
Set attributes for each of them.
Set content to :before and :after by the attributes
Style those pseudo elements.
This solution will works only with 1 comma separation.
[].forEach.call(document.querySelectorAll('div'), function(item) {
// check if there is a , in the text
if (item.innerText.indexOf(',') > -1) {
var texts = item.innerText.split(',');
item.setAttribute('data-text1', texts[0]);
item.setAttribute('data-text2', texts[1]);
item.innerHTML = ',';
}
});
div:before {
content:attr(data-text1);
color:red;
}
div:after {
content:attr(data-text2);
color:yellow;
}
<div data-value="ABCD,XYZ" style="padding-left: 12px; padding-right: 12px;">ABCD,XYZ</div>
<div data-value="ABCD,XYZ" style="padding-left: 12px; padding-right: 12px;">cdE,hhhh</div>

Moving Javascript variables into Html Table

i found this guide to create a stock ticker.
I tried to change it into an html table, but i'm stuck.
So, i created the table, but i have big problems to divide each variable.
What i want to accomplish is a table with this columns order:
Symbol: CompName
Price: Price
Change: PriceIcon + ChnageInPrice
%: PercentChnageInPrice
What i've accomplished for now it's just this, all the content in one column (because of the variable StockTickerHTML i guess)
Full Code Link
Can you please help me?
var CNames = "^FTSE,FTSEMIB.MI,^IXIC,^N225,^HSI,EURUSD=X";
var flickerAPI = "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22" + CNames + "%22)&env=store://datatables.org/alltableswithkeys";
var StockTickerHTML = "";
var StockTickerXML = $.get(flickerAPI, function(xml) {
$(xml).find("quote").each(function () {
Symbol = $(this).attr("symbol");
$(this).find("Name").each(function () {
CompName = $(this).text();
});
$(this).find("LastTradePriceOnly").each(function () {
Price = $(this).text();
});
$(this).find("Change").each(function () {
ChnageInPrice = $(this).text();
});
$(this).find("PercentChange").each(function () {
PercentChnageInPrice = $(this).text();
});
var PriceClass = "GreenText", PriceIcon="up_green";
if(parseFloat(ChnageInPrice) < 0) { PriceClass = "RedText"; PriceIcon="down_red"; }
StockTickerHTML = StockTickerHTML + "<span class='" + PriceClass + "'>";
StockTickerHTML = StockTickerHTML + "<span class='quote'>" + CompName + " </span> ";
StockTickerHTML = StockTickerHTML + parseFloat(Price).toFixed(2) + " ";
StockTickerHTML = StockTickerHTML + "<span class='" + PriceIcon + "'></span>" + parseFloat(Math.abs(ChnageInPrice)).toFixed(2) + " (";
StockTickerHTML = StockTickerHTML + parseFloat( Math.abs(PercentChnageInPrice.split('%')[0])).toFixed(2) + "%)</span> </br>";
});
$("#dvStockTicker").html(StockTickerHTML);
$("#dvStockTicker").jStockTicker({interval: 30, speed: 2});
});
}

One solution could be this :
(see comments in code)
$(window).load(function() {
StockPriceTicker();
setInterval(function() {
StockPriceTicker();
}, 2 * 1000); // <------ we refresh each 2 seconds
});
// we get the table's body where
// the lines will be inserted.
var $body = $('table tbody');
/*
this will be the cache of
our lines, once they are prepared / transformed
as your need, we will join and insert them
in the body of our table.
*/
var Lines = [];
/*
We define a function in charge of creating the HTML
of each row of hour table, and then push them
in the array defined above "Lines".
*/
var addLine = function(symbol, price, change, percent) {
Lines.push('<tr>' +
'<td class="symbol" >' + symbol + '</td>' +
'<td class="price" >' + price + '</td>' +
'<td class="change" >' + change + '</td>' +
'<td class="percent">' + percent + '</td>' +
'</tr>');
};
// this is your function to get data
function StockPriceTicker() {
var Symbol = "",
CompName = "",
Price = "",
ChnageInPrice = "",
PercentChnageInPrice = "";
var CNames = "^FTSE,FTSEMIB.MI,^IXIC,^N225,^HSI,EURUSD=X";
var flickerAPI = "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22" + CNames + "%22)&env=store://datatables.org/alltableswithkeys";
var StockTickerXML = $.get(flickerAPI, function(xml) {
$(xml).find("quote").each(function() {
Symbol = $(this).attr("symbol");
$(this).find("Name").each(function() {
CompName = $(this).text();
});
$(this).find("LastTradePriceOnly").each(function() {
Price = $(this).text();
});
$(this).find("Change").each(function() {
ChnageInPrice = $(this).text();
});
$(this).find("PercentChange").each(function() {
PercentChnageInPrice = $(this).text();
});
var PriceClass = "GreenText",
PriceIcon = "up_green";
if (parseFloat(ChnageInPrice) < 0) {
PriceClass = "RedText";
PriceIcon = "down_red";
}
/*
We create the html to be inserted on each xml loop.
- First : prepare and transform as you need
- Last : use the function we define above "addLine";
*/
var htmlSymbol,

htmlPercent = parseFloat(Math.abs(PercentChnageInPrice.split('%')[0])).toFixed(2) + "%";
// We use here the function defined above.
addLine(htmlSymbol, htmlPrice, htmlChange, htmlPercent);
});
/*
Once the loop of reading the XML
end, we have pushed all html in the array "Lines".
So now we delete the content of our table's body, and
we fill it with all the lines joined.

$body.empty().html(Lines.join(''));

change font size after decimal point

I am working with an Opencart E-Commerce website, I need to customize product price font size,
for example:
product price: $ 250.50 i need to set font size for $ = 16px; 250 = 22px; .50 = 14px;
How can I set different font sizes for a single amount..???
this s my dynamic php code that display price text to my product page:
<span class="price"><?php echo $product['price']; ?></span>
my product list page not a single product with price, there is a lots of product with price list.
thanks for any help, if anybody asked the same question before here, please share with me those links...

$.each($('.price'), function(){
var price = $(this).html();
$(this).html(price.replace(/(\D*)(\d*\.)(\d*)/,'<span style="font-size:16px;">$1</span><span style="font-size:22px;">$2</span><span style="font-size:14px;">$3</span>'));
});
http://jsfiddle.net/gr8x5/10/

Here's a quick and dirty example:
<html>
<head>
<style>
.dollar_sign { font-size: 16px; }
.dollars { font-size: 22px; }
.cents { font-size: 14px; }
</style>
</head>
<body>
<?
$product = array('price' => '245.50');
$part = explode('.', $product['price']);
?>
<span class="dollar_sign">$</span><span class="dollars"><?= $part[0] ?></span>.<span class="cents"><?= $part[1] ?></span>
</body>
</html>

Try this code
var pri = $(".price").text();
var sig = pri.split(" ");
var dol_smbl = "<span style='font-size:16px;'>" + sig[0] + "</span>";
var digits = sig[1].split(".");
befr_dec = "<span style='font-size:22px;'>" + digits[0] + "</span>";
aftr_dec = "<span style='font-size:14px;'>." + digits[1] + "</span>";
$(".price").html(dol_smbl + " " + befr_dec + aftr_dec);

Can be beautifully done with a little css and regex. See this fiddle
the HTML :
<span class="price">$250.50</span>
the css :
.currency { font-size:16px; }
.number { font-size:22px; }
.decimal { font-size:14px; }
the javascript :
var price = $('span.price').text();
var pArry = price.match(/^(\$)(\d+)(\.\d+)?/);
var new_span = $(
'<span class="currency">' + pArry[1] + '</span>' +
'<span class="number">' + pArry[2] + '</span>' +
'<span class="decimal">' + pArry[3] + '</span>');
$('span.price').replaceWith(new_span);
Done

Try like this
var my_price = $(".price").text();
var dol_smbl = "<span style='font-size:16px;'>"+my_price[0]+"</span>";
var price = split(" ",my_price);
var price_arr = split('.',price[1]);
befr_dec = "<span style='font-size:22px;'>"+price_arr[0]+"</span>";
aftr_dec = "<span style='font-size:14px;'>."+price_arr[1]+"</span>";
$(".price").html(dol_smbl + " " + befr_dec + aftr_dec);

The easiest way would be to split up that var? Look at the php function explode().
http://php.net/manual/de/function.explode.php

You can try this generic approach
$('.price').each(function () {
var $this = $(this),
txt = $this.text(),
splt = txt.split('.'),
spltFirst = splt.pop(),
spn3 = $('<span/>', {
text: spltFirst,
'class': 'font-small'
}),
spltSecond = splt.pop(),
spn1 = $('<span/>', {
text: spltSecond.substring(0, spltSecond.lastIndexOf('$') + 1),
'class': 'font-medium'
}),
spn2 = $('<span/>', {
text: spltSecond.substring(spltSecond.lastIndexOf('$') + 1) + '.',
'class': 'font-big'
});
$this.text('');
$this.append(spn1).append(spn2).append(spn3);
});
Check Fiddle

Use different span element for those three different segments and set class for them individually to assign different font styles. Basically spans are inline element, so you dont need to worry about its placement.
For example:
After rendering your markup should be like this,
<span class="price">
<span class="currencySymbol">$</span>
<span class="amt1">250</span>
<span class="amt2">.50</span>
</span>
then in CSS:
.currencySymbol{ font-size:16px; }
.amt1{ font-size:22px; }
.amt2{ font-size:14px; }

A possible simple dynamic way using only split().
This will wrap decimals in a <small> tag on each element having a class format .
document.querySelectorAll(".format").forEach((e) => {
let txt = e.innerHTML.split(".")
e.innerHTML = txt[0] + ".<small>" + txt[1] + "</small>"
})
.format {font-size:3rem}
small {font-size:1.4rem}
<div class="format">34454.545432</div>
<div class="format">0.0000463533</div>
<div class="format"><mark>Hello</mark> -8765.9876</div>
