Copy HTML from element, replace text with jQuery, then append to element

I am trying to create portlets on my website which are generated when a user inputs a number and clicks a button.
I have the HTML in a script tag (that way it's invisible). I am able to clone the HTML contents of the script tag and append it to the necessary element without issue. My problem is, I cannot seem to modify the text inside the template before appending it.
This is a super simplified version of what I'd like to do. I'm just trying to get parts of it working properly before building it up more.
Here is the script tag with the template:
var p = $("#tpl_dashboard_portlet").html();
var h = document.createElement('div');
$(h).html(p);
$(h).find('div.m-portlet').data('s', s);
$(h).find('[data-key="number"]').val(s);
$(h).find('[data-key="name"]').val("TEST");
console.log(h);
console.log($(h).html());
console.log(s);
$("div.m-content").append($(h).html());
<script id="tpl_dashboard_portlet" type="text/html">
<!--begin::Portlet-->
<div class="m-portlet">
<div class="m-portlet__head">
<div class="m-portlet__head-caption">
<div class="m-portlet__head-title">
<h3 class="m-portlet__head-text">
<span data-key="number"></span> [<span data-key="name"></span>]
</h3>
</div>
</div>
<div class="m-portlet__head-tools">
<ul class="m-portlet_nav">
<li class="m-portlet__nav-item">
<i class="la la-close"></i>
</li>
</ul>
</div>
</div>
<!--begin::Form-->
<div class="m-portlet__body">
Found! <span data-key="number"></span> [<span data-key="name"></span>]
</div>
</div>
<!--end::Portlet-->
</script>
I'm not sure what I'm doing wrong here. I've tried using .each as well with no luck. Both leave the value of the span tags empty.
(I've removed some of the script, but the variable s does have a value on it)

You have two issues here. Firstly, every time you call $(h) you're creating a new jQuery object from the original template HTML. As such any and all previous changes you made are lost. You need to create the jQuery object from the template HTML once, then make all changes to that object.
Secondly, the span elements you select by data-key attribute do not have value properties to change, you instead need to set their text(). Try this:
var s = 'foo';
var p = $("#tpl_dashboard_portlet").html();
var $h = $('<div />');
$h.html(p);
$h.find('div.m-portlet').data('s', s);
$h.find('[data-key="number"]').text(s);
$h.find('[data-key="name"]').text("TEST");
$("div.m-content").append($h.html());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script id="tpl_dashboard_portlet" type="text/html">
<div class="m-portlet">
<div class="m-portlet__head">
<div class="m-portlet__head-caption">
<div class="m-portlet__head-title">
<h3 class="m-portlet__head-text">
<span data-key="number"></span> [<span data-key="name"></span>]
</h3>
</div>
</div>
<div class="m-portlet__head-tools">
<ul class="m-portlet_nav">
<li class="m-portlet__nav-item">
<i class="la la-close"></i>
</li>
</ul>
</div>
</div>
<div class="m-portlet__body">
Found! <span data-key="number"></span> [<span data-key="name"></span>]
</div>
</div>
</script>
<div class="m-content"></div>

In my case only this is working:
var template = $('template').clone(true, true); // Copies all data and events
var $h = $('<div />');
$h.html(template);
$h.find('.input-name').attr('value', "your value here"); // Note: .val("your value here") is not working
$('.list').prepend($h.html());

Get Nth class of an element having multiple class with out using .attr("class") in jquery

In a div with two classes, the first inner div
<div class="datacheck">
<div class="classic_div_data customdataid_305">
some values come here
</div>
<div class="optiondiv">
</div>
</div>
I need to get a substring (here the number 305) from the second class(customdataid_305) of the first inner div. For this need to get the classes.
I wrote in jquery and succeed
var xyz= $($(".datacheck").find("div")[0]).attr("class").split(" ")[1]
from which I gets the class.
Is there any simpler approach for this.
I am searching for something like this $(element).class() probably returns an array of classes

There's nothing that gives you an array of classes, although the native DOM classList is close. But I don't think classList will make things much simpler.
I'd do this:
var xyz = $(".datacheck .classic_div_data").attr("class").match(/\bcustomdataid_(\d+)\b/);
xyz = xyz && xyz[1];
The regex extracts the numeric portion of the class, without being fragile (sensitive to whether the class is the first or second in the list of classes, for instance).
Example:
var xyz = $(".datacheck .classic_div_data").attr("class").match(/\bcustomdataid_(\d+)\b/);
xyz = xyz && xyz[1];
console.log("xyz = '" + xyz + "'");
<div class="datacheck">
<div class="classic_div_data customdataid_305">
some values come here
</div>
<div class="optiondiv">
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
If you can change the HTML, though, I wouldn't use a class for this at all, I'd us a data-* attribute instead:
<div class="classic_div_data" data-custom-id="305">
then
var xyz = $(".datacheck [data-custom-id]").attr("data-custom-id");
Example:
var xyz = $(".datacheck [data-custom-id]").attr("data-custom-id");
console.log("xyz = '" + xyz + "'");
<div class="datacheck">
<div class="classic_div_data" data-custom-id="305">
some values come here
</div>
<div class="optiondiv">
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

One of the major problems you have with your current design is that if the order of the classes changes, or someone adds another class, your logic breaks. You're also getting a DOMElement from a jQuery object which you turn back in to a jQuery object again.
It would be a much better approach to use data-* attributes to store your custom data, like this:
$('.classic_div_data').click(function() {
console.log($(this).data('customdataid'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="datacheck">
<div class="classic_div_data" data-customdataid="305">
some values come here
</div>
<div class="optiondiv"></div>
</div>
<div class="datacheck">
<div class="classic_div_data" data-customdataid="205">
some more values come here
</div>
<div class="optiondiv"></div>
</div>

You can get the nth class easily from the classList of element object,
var x = $(".datacheck").find("div").get(0);
var nthClass = x.classList[1]
var res = nthClass.replace("customdataid_", "");
console.log(res); //305

You can use regex in .match() to finding last digit in class.
var digit = $(".datacheck > :first").attr("class").match(/[\d]+$/g)[0];
console.log(digit);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="datacheck">
<div class="classic_div_data customdataid_305">some values come here</div>
<div class="optiondiv"></div>
</div>

Changing Div content based on Geo IP

I currently have a website that is showing a price for a product within a <div>. I would like this number to change if the user is from outside the UK, for example changing the price to Euros rather than GBP.
Is this possible? I can't find an example I understand.

You should give more example info but Im not going to be so critical.
You could capture the location using google maps if they agree to it, or ip address and then set a class to all the price divs and price symbol divs.
try something like this
<div id="parent_id">
<div class="item">
<span class="symbol">£</span> <div class="price_divs" id="div1">5.00</div>
</div>
<div class="item">
<span class="symbol">£</span> <div class="price_divs" id="div2">5.00</div>
</div>
<div class="item">
<span class="symbol">£</span> <div class="price_divs" id="div3">5.00</div>
</div>
</div>
<script>
jQuery(function(){ ///requires jquery
if(location == "US"){ //location must be a global variable given a value from google maps
var all_pricing = $('#parent_id').find('.price_divs');
$('.symbol').html('$');
$.each(all_pricing,function(x,y){
var c = convertToDollars($('#'+y.id).html());
$('#'+y.id).html(c);
});
}
function convertToDollars(cost)
{
///some conversion here
return cost;
}
});
</script>

jQuery Replicate an existing Div Multiple Times

I am building a search query which gives me results.
I have a template ready for the item inside a hidden div. What I want to do is replicate the template n number of times using jQuery.
So For example:
I search for flights and I get 5 search results, I need to replicate the below div template 5 Times
<div id="oneWayFlightElement" class="displayNone">
<div id="flightIndex1" class="flightDetailElement boxShadowTheme">
<div id="flightDetailsLeftPanel1" class="flightDetailsLeftPanel marginBottom10">
<div class="fullWidth marginTop10">
<span id="flightPriceLabel1" class="headerFontStyle fullWidth boldFont">Rs 9500.00</span><hr/>
<div id="homeToDestination1" class="flightBlockStyle">
<span id="flightNumberFromHome1" class="fontSize16">AI-202</span><br/>
<span id="flightRouteFromHome1" class="fontSize26">PNQ > DEL</span><br/>
<span id="flightDepartTimeFromHome1" class="fontSize26">Depart: 10.00 AM</span><br/>
<span id="flightArrivalTimeFromHome1" class="fontSize26">Arrive: 12.00 PM</span><br/>
</div>
<div id="destinationToHome1" class="flightBlockStyle">
<span id="flightNumberToHome1" class="fontSize16">AI-202</span><br/>
<span id="flightRouteToHome1" class="fontSize26">PNQ > DEL</span><br/>
<span id="flightDepartTimeToHome1" class="fontSize26">Depart: 10.00 AM</span><br/>
<span id="flightArrivalTimeToHome1" class="fontSize26">Arrive: 12.00 PM</span><br/>
</div>
</div>
</div>
<div id="flightDetailsRightPanel1" class="flightDetailsRightPanel textAlignRight marginBottom10">
<img src="images/flightIcon.png" class="marginRight10 marginTop10 width40"/><br/>
<button class="marginRight10 marginBottom10 width40 bookNowButtonStyle">Book Now</button>
</div>
</div>
</div>
Inside this div for 5 times
<div id="searchFlightResultDiv" class="fullWidth" style="border:solid">
</div>
Is there a better way to do that rather than string appending in jQuery?
Thanks,
Ankit Tanna

You'll need to wrap your template div (#flightIndex1) in a container with a unique id attribute. Then, you take the contents of that container (a template for a single record), and append it to your results div (#searchFlightResultDiv) using some type of loop based on the number of results received.
Basically,
HTML:
<!-- Here's your template -->
<div class="displayNone" id="oneWayFlightElement">
<!-- This id (singleResult) is important -->
<div id="singleResult">Result</div>
</div>
<!-- Container for the results -->
<div id="results"></div>
Javascript:
//Get the number of results.
//This can be sent from your API or however you're getting the data.
//For example, in PHP you would set this to $query->num_rows();
var count = 5;
//Start a for loop to clone the template element (div#singleResult) into div#results 'count' times.
//This will repeat until the number of records (count) has been reached.
for (i = 1; i <= count; i++) {
//Append the HTML from div#thingToRepeat into the #results.
$('#results').append($('#singleResult').clone());
}
Here's a JSFiddle to show you how it works. You can play with it and tweak it if necessary.
I can't in good conscious complete this post without telling you the downsides of this. Doing it this way is majorly frowned upon in the web development community and is super inefficient. It may be good for practice and learning, but please do take a look at and consider a javascript templating framework like moustache or handlebars. It does this same thing but way more efficiently.
Hope this was helpful!

function populateResult(resCount) {
resCount = typeof resCount === 'number' ? resCount : 0;
var res = [];
var templateEle = $('#oneWayFlightElement');
for(var i = 0; i < resCount; ++i)
res.push(templateEle.clone().removeAttr('id class')[0]);
$('#searchFlightResultDiv').html(res);
}
populateResult(5);
We use an array res to hold the DOM elements as we loop and finally sets it to the target div using html method. We don't need a JQuery object here as the html method accepts any array like object. In this way we can minimize browser reflows. Here is the JSFiddle

Get specific data from page and write it to div

I'm building an online store with javascript shopping cart. However, the script doesn't allow printing only one or two values when displaying cart, but I need to do this.
Here's what the cart looks like:
<div class="simpleCart_items">
<div>
<div class="headerRow">
<div class="item-name">Tuote</div>
<div class="item-price">Hinta</div>
<div class="item-decrement">-</div>
<div class="item-quantity">Määrä</div>
<div class="item-increment">+</div>
<div class="item-total">Yhteensä</div>
<div class="item-remove">Poista</div>
</div>
<div class="itemRow row-0 odd" id="cartItem_SCI-1">
<div class="item-name">Teipit</div>
<div class="item-price">€0.00</div>
<div class="item-decrement"><img src="css/minus.png" alt="minus">
</div>
<div class="item-quantity">3</div>
<div class="item-increment"><img src="css/plus.png" alt="plus">
</div>
<div class="item-total">€0.00</div>
<div class="item-remove"><img src="css/remove.png" alt="Remove">
</div>
</div>
<div class="itemRow row-1 even" id="cartItem_SCI-3">
<div class="item-name">Car Speaker -hajuste</div>
<div class="item-price">€4.00</div>
<div class="item-decrement"><img src="css/minus.png" alt="minus">
</div>
<div class="item-quantity">1</div>
<div class="item-increment"><img src="css/plus.png" alt="plus">
</div>
<div class="item-total">€4.00</div>
<div class="item-remove"><img src="css/remove.png" alt="Remove">
</div>
</div>
<div class="itemRow row-2 odd" id="cartItem_SCI-5">
<div class="item-name">Teipit (Musta hiilikuitu)</div>
<div class="item-price">€0.00</div>
<div class="item-decrement"><img src="css/minus.png" alt="minus">
</div>
<div class="item-quantity">1</div>
<div class="item-increment"><img src="css/plus.png" alt="plus">
</div>
<div class="item-total">€0.00</div>
<div class="item-remove"><img src="css/remove.png" alt="Remove">
</div>
</div>
</div>
</div>
NOTE: The cart is written via javascript so it isn't visible in page source, only in inspect mode of the browser.
So how would I gather the item-name, item-priceand item-quantity?
I've tried this:
var name = $('.item-name');
var price = $('.item-price');
var quantity = $('.item-quantity');
var data = name + price + quantity;
$('#items').html(data);
But this won't actually do anything.

When doing this -> $('.item-name');
You are just capturing the element as object but not the value.
Now that you got your element as object, you need to extract the value and, in this case, your element object is a div so you can try .text() or .html() (to get the text or html inside the div).
(For this situation I will use text() cause you are working just with values and there is nothing related to html)
Try this:
var name = $('.item-name');
var price = $('.item-price');
var quantity = $('.item-quantity');
var data = name.text() + price.text() + quantity.text();
$('#items').html(data);
Better solution:
This will make clickable the div in which you have the product and match the cartItem_SCI pattern.
So, when user clicks any of the elements of your cart, you will get the name, price and quantity values that will be attached to the $('#items') div using append() method instead of html() (because using this will replace the product information each time the user clicks a div)
$(document).ready(function() {
$('div[id^="cartItem_SCI-"]').css({ cursor:'pointer' });
$('div[id^="cartItem_SCI-"]').click(function() {
var name = $(this).find('.item-name');
var price = $(this).find('.item-price');
var quantity = $(this).find('.item-quantity');
var data = name.text() + ' - ' + price.text() + ' - ' + quantity.text();
$('#items').append(data + '<br/>');
});
});​

You are just getting a reference to the class, add .html() to get the inner html of the element that the class applied to.
var name = $('.item-name').html();

For one item you can get like this.But since you have multiple items make one object like this .
var item={};
$('.item-name').each(function(){item.name=$(this).html()});
$('.item-price').each(function(){item.price=$(this).html()});
$('.item-quantity').each(function(){item.quantity=$(this).html()});
var data='';
for(var i=0;i<item.length;i++)
{
data+=item[i].name+item[i].price+item[i].quantity;
}
$('#items').html(data);
