I have a report builder that when served up has several div elements with charts and graphs. Now the user can dragged and sorted these elements how they wish. My issue now is how to capture the html page so the PDF will reflect this new layout.
Before I was capturing the html page in Coldfusions cfsavecontent and sending that to a process page to create the pdf. This does not work when elements have been dragged and sorted dynamically. Any ideas or suggestions would be helpful. Thanks.
<form name="fform" action="process.cfm" method="post" target="iprocess">
<cfsavecontent variable="strPDF">
<div id='graph1'>
<div style='position:absolute; top:500px; left:175px'>
<span>Report Data Here</span>
</div>
</div>
<div id='graph2'>
<div style='position:absolute; top:500px; left:175px'>
<span>Report Data Here</span>
</div>
</div>
<div id='graph3'>
<div style='position:absolute; top:575px; left:175px'>
<span>Report Data Here</span>
</div>
</div>
</cfsavecontent>
<input type="hidden" name="strPDF" value="#strPDF#">
<input type="submit" value="Create PDF">
<div>
<div>#strPDF#</div>
</div>
</form>
<iframe height="300" width="700" src="" name="iprocess"></iframe>
JQuery is used to make the elements draggable. Is it possible to recapture the page to pdf with the new element positions?
Answer = No (there... that was simple.)
TL;DR
Ok let me see if I understand this right. You have a page with charts and dynamic content that allows user experience customization.
You have report builder, you are serving up charts with what? with cfchart? and you were at one time doing a cfsavecontent to a variable but you are not doing that now. So what are you doing? Forget it...it doesn't matter.
Let me tell you what I have to do and I think you might want to consider something similar.
I have my page of charts that are .png generated serverside via cfchart. I do a cfsavecontent grabbing the variable and doing a cfdocument PDF generation. This will give your people or person something to print and look at. It meets whatever PDF print requirements you might have. The PDF styling no matter how you slice it is limited. you will no doubt have already experienced styling give and take when you look at your generated page of charts and divs, and your PDF output page side by side.
If you want client customizations (dragging things and what not). Then store those as user preferences in a table and when they return you can set things up a certain way and then have that variable handy you can generate a PDF based on that.
Understand that PDF does not follow 'all styling behaviors'. You will need to consider your give and take scenarios. If the user wants to print something like a chart, then my god man...keep it super simple and keep it all native in coldfusion: cfchart, cfsavecontent, cfdocument.
Good luck.

I am working on a school project and I have to do a static digital menu website for a bar. Because it's static, I used JavaScript where necessary. Anyways, I divided everything into groups, each group is represented by a card with an image and a button. Here is an example:
This is the source code for a card:
<body>
<div id="cards">
<div class="card">
<img src="/Resources/Food.png" class="card_image">
<a href="javascript:showMenu()" class="button">
<p>FOOD</p>
</a>
</div>
</div>
</body>
As you can see, in order to add a single card, I had to manually write the whole structure of a card in the second div, with the class="card".
BUT, I must create it dynamically based on the structure of the subfolders inside the Root folder witch is called Resources, here's a scheme:
In order to achieve this I started using JavaScript since it's the only possible way I think:
<script type="text/javascript">
function showMenu()
{
var content = `
<div class="card">
<img src="/Resources/Food.png" class="card_image">
<a href="javascript:showMenu()" class="button">
<p>FOOD</p>
</a>
</div>`;
document.querySelector("#cards").innerHTML = content;
}
</script>
So, now that I've expressed what I need to do is this: in the JavaScript code you can see that the card was generated manually anyways but I need the content to generate based on the folder structure I have stored locally. In other words, the whole script should take in input the name/path of the ROOT folder which is called "Resources" and from there it should generate the groups based on it's content. For example, if I click the button on the FOOD Card, then it should delete the FOOD and DRINKS Cards and only add the Vegetables Card in this case...I know it sounds complicated but at the end of the day the problem lies in getting the subfolder names, and since the image has the same name of the subfolder, apply it on the <img> tag and also on the button. All this, using JavaScript. If you know that some other language would work much better I'm open to suggestions, but I built the entire website until now only using JavaScript.
Anyways, I tried to express the problem the best I could so if something is unclear, I can easily modify the post if needed. Thanks in advance!
You could put the image data into a JSON object, then bind related processing functions according to the requirement.
When loading data using AJAX, what is preferred:
Loading html data e.g.
<div class="message">
<span class="author">John Smith</span>
<span class="date">01/01/17</span>
<div class="message-content">
Example text
</div>
<div class="message-actions">
Upvote
Downvote
Leave a comment
</div>
</div>
(The above is entirely fictional, by the way)
Or loading JSON data e.g.
{
"author":"John Smith",
"date":"01/01/17",
"text":"Example Text"
}
I realise that loading JSON data would place less load on the server, but I'm primarily concerned about loading speed for the user. So basically, my question is, how does loading html data-for example using JQuery's .load() method, compare to loading JSON data and rendering it as html using Javascript, in terms of total time before a user can see the displayed result?

This is a messaging application, and so these messages will be displayed one after the other in a scrolling area of the screen. The number of messages is variable.
My webstore uses Kudobuzz for product reviews, but our e-commerce platform (PDG) isn't supported for SEO markup data.
This widget does not support schema markup on it's own, so I want to somehow select the relevant pieces and inject the schema markup to the various divs/spans that make up the widget. One problem is figuring out how to inject code that google can parse, and another is figuring out how to make the actual selectors for this super bloated widget.
Here is a codepin of the widget and some markup data that is already on the site: http://codepen.io/anon/pen/GpddpO
Here is a link to a product page if you want to see how everything works: https://www.asseenontvhot10.com/product/2835/Professional-Leather--Vinyl-Repair-Kit
This is (roughly) the markup I'm trying to add if it helps:
<div itemscope itemtype="http://schema.org/Review">
<div itemprop="reviewBody">Blah Blah it works 5 star</div>
<div itemprop="author" itemscope itemtype="http://schema.org/Person">
Written by: <span itemprop="name">Author</span></div>
<div itemprop="itemReviewed" itemscope itemtype="http://schema.org/Thing">
<span itemprop="name">Stop Snore</span></div>
<div><meta itemprop="datePublished" content="2015-10-07">Date published: 10/07/2015</div>
<div itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating">
<meta itemprop="worstRating" content="1"><span itemprop="ratingValue">5</span> / <span itemprop="bestRating">5</span> stars</div>
</div>
Theoretically you could write a very small amount of microdata using css :before and :after - with content but it would need all spaces and symbols converted into ISO format, eg.
#name:before { "\003cspan\2002itemprop\0022name\2033"}
#name:after { content: "\2044\003cspan003e"
even spaces need to be substitued with \2002 or an equivalent whitespace
code
should wrap this microdata to your HTML to any element called name:
<span itemprop="name">...</span>
Clearly this can only work if the widget lets you have clear ids or class names for the elements added, and it may be useless you know the type of object reviewed first (eg Book, Movie, since this needs to go at the start in the example I gave - which is incomplete). The code would need to be nested correctly so if you want further help can you edit your question with example HTML for a completed review.
Writing your own JSON-LD script at the top of the page is another option - it would be a different question (if you get stuck) but isn't embedded within the data itself
Edit
it's a good idea to test the css in a separate environment first, eg setup a jsfiddle
I want to search multiple HTML files from a separate page, where I search for text from all the divs which has a specific id for each, whole id containing matched search term will be displayed on the search page in list.
The div list looks like this :
<body>
<div class='vs'>
<div id='header 1'>content 1 here </div>
<div id='header 2'>another text </div>
<div id='header 3'>whatever </div>
</div>
</body>
Please note that I want to perform search from different page and want to display results there with links to the searchable page.
For now I was searching like this :
HTML
<body>
<input type="text" id='search' />
<div class='vs'>
<div id='header 1'>content 1 here </div>
<div id='header 2'>another text </div>
<div id='header 3'>whatever </div>
</div>
</body>
JavaScript
$('#search').on('input', function () {
var text = $(this).val();
$('.vs div').show();
$('.vs div:not(:contains(' + text + '))').hide();
});
It is working on the fiddle here, but I don't want it to work like this, I want to do the search from a separate page remotely and display results there with link to this page.
Solution with jQuery and AJAX:
<form id="searchForm">
<input type="text" id="search"/>
<input type="submit" name="Search!" />
</form>
<div id="resultContainer">
</div>
<script type="text/javascript">
$("#searchForm").submit(function(e) {
e.preventDefault();
var results = $("#resultContainer");
var text = $("#search").val();
results.empty();
$.get("http://example.com/", function(data) {
results.append($(data).find("div:contains(" + text + ")"));
});
});
</script>
Fiddle (This fiddle enables you to search for content on the jsfiddle page, try for example JSFiddle as search term.)
Note however that this does not work cross-domain, because browsers will prevent cross-site scripting. You didn't describe your use-case clear enough for me to know whether you're okay with that.
You'll want to look at using PHP file_get_contents to retrieve the HTML contents of the external page, and from there analyze the data in the <div>s that you are interested in. Ultimately, you'll want to store each individual search term in a JavaScript array (you can create JavaScript arrays dynamically using PHP), and then create search functionality similar to example you posted to search all the elements in your array.
So on page load, you'll want to have a <div> in which you are going to list all the elements from the array. You can list these by looping through the array and displaying each individual element. From there, you will want to call a function every time the user enters or deletes a character in the <input> box. This function will update the <div> with an updated list of elements that match the string in the <input> box.
This is the theory behind what you are trying to accomplish. Hopefully it will give you some direction as to how to write your code.
Update:
If you're looking for a JavaScript only solution, check out a JavaScript equivalent of PHP's file_get_contents: http://phpjs.org/functions/file_get_contents/
From here, you can maybe look at using .split to break up the list. Ultimately, you're still trying to store each individual search term as an element in an array, it's just the method that you retrieve these terms is different (JavaScript as opposed to PHP).
Perhaps I was emphasizing too much on PHP, perhaps it's because it's the web development language I'm most familiar with. Hope this JavaScript-only solution is helpful.
I am currently working on a project that lets users post comments with jquery and ajax. So far it is using Json and retunring several items, username, comment text, user photo url, comment ID number and stuff like that, I then need to use some sort of template to make all this data go into the correct div's before adding it all to the screen.
I am new to using javascript so this is a hard task for me. I am now considering the easy route.
Just have my PHP backend script return the whole block of code, div's and everything in place but I am wondering is this a bad idea? More importantly is it a bad idea with json?
Here is an example of a block of code that needs to be added to the screen when a comment is posted
<li class="admin" id="comment-1371">
<div class="photocolumn">
<!-- START Photo block -->
<div class="imageSub" style="width: 100px;">
<img class="male" src="http://cache2.mycrib.net/images/image_group34/0/39/T_653807517aff2b1f5662d865b40d87d527c8eb.jpg" alt="Something" width="100"/>
<div class="blackbg"></div>
<div class="label">JasonDavis</div>
</div>
<!-- END Photo block -->
</div><!-- END photocolumn -->
<div class="commenttext">
<p>02/12/3009</p>
<p>sample text for comment area!</p>
</div>
<!-- END COMMENTTEXT -->
</li>
I would say it depends on the situation/application. For instance I would use json and templating for a flight/hotel etc result screen. Why return 50k's worth of the same markup when a 4k json object will do and will allow for rapid clientside sort/filter. If you dont need quick clientside filtering/sorting then responding with dom fragments is ok. Horses for courses.
I don't see a problem with returning HTML via AJAX. A bonus of this is that you can generate most of the HTML in a view in PHP and still keep things fairly clean.
Tokenizing your data into an object is nice for re-use but can be overkill for a one-off.
Go the easy route, I can see no reasons of going with JSON array.
