Can I get some help decoding this bit of a Facebook page? - javascript

I'm trying to figure out just how a particular function works on a Facebook page, and being no friend of JS syntax, am having trouble. Here's the question mark bit:
<a href="#" clicktoshowdialog="my_dialog" onclick="
(new Image()).src = '/ajax/ct.php?app_id=4949752878&action_type=3&post_form_id=3b933f46f9c4c44981e51b90c754bfce&position=2&' + Math.random();
FBML.clickToShowDialog("app4949752878_my_dialog");
return false;">
<img src="linktopicture" title="Are your friends fans?" width="190" height="230" />
</a>
<div style="display:none">
<div id="app4949752878_my_dialog" fbcontext="aa3fcff8e653">
<div class="app_content_4949752878" style="padding:10px">
<div with hidden then exposed content...
The functionality of this is an image that, when clicked, pops out the previously hidden div. I know that the app###### is prepended to all JS used in Facebook to limit its scope. I'm confused by the anchor parameter of
clicktoshowdialog="mydialog"
What is that identifying, and how is it targeting the div that's exposed when the image is clicked? Thanks for any clarification, and let me know if I can post any more sample code.

According to the wiki it's just for opening the dialog (which is defined at the bottom). Facebook generates the JS to open the dialog. The attribute got post-processed and the JS code (that you see in the onclick= attribute) was generated on it's basis.

Google Tag Manager - CSS selector challenge

I am trying to get the URL of a link in the source code. The challenge is that the URL is hidden behind a image, and thus only letting me fetch the image-url.
I've been trying to figure a way to solve this issue by using the new CSS selector in the trigger system and also made a DOM variable that should get the URL when the image is clicked. There can also be multiple downloads.
Here is an example of what I am trying to achieve:
<div>
<div class="download">
<a href="example.com/The-URL-I-Want-to-get-if-top-image-is-clicked.pdf" target="_blank">
<img src="some-download-image.png"/></a>
<div class="download">
<a href="example.com/Another-URL-I-Want-to-get-if-middle-image-is-clicked.pdf" target="_blank">
<img src="some-download-image.png"/></a>
<div class="download">
<a href="example.com/Last-URL-I-Want-to-get-if-bottom-image-is-clicked.pdf" target="_blank">
<img src="some-download-image.png"/></a>
</div>
</div>
There are much code above and below this snippet, but with the selector it should be fairly easy to get the information I want. Only that I don't.
If anyone have met this wall and solved it, I really would like to know how. :)
This is one possible solution. So as I understand it, you would like to grab the anchor element's href attribute when you click the "download" image.
A Custom Javascript variable would need to be created so that you can manipulate the click element object:
function(){
var ec = {{Click Element}};
var href = $(ec).closest('a').attr('href');
return href;
}
So you will need to do your due diligence and add in your error checking and stuff, but basically this should return to you the href, and then you will need to parse the string to extract the portion that you need.

Changing anchor tag text while using PhoneGap and jQuery

As a preface, I am using PhoneGap. When I click on a Category Title, I have taken that title and set it in sessionStorage. Now, I want to set the "back" button of a new PhoneGap page (which displays some information contained in that category) to that Category Title. The HTML code is shown below. To be specific, I want to change the text of the "a" element within the "header" element.
I guess a part of my question is, does the fact that I am using PhoneGap change how I can access the anchor tag? I've been trying to set the back button text right after the Category has been selected/clicked on. I have tried multiple things like:
$("adviceBodyNavbarHeader a").text(sessionStorage.getItem("catTitle"));
but I can't quite get it working, and it is getting quite frustrating =/
<div data-role="view" id="adviceBody" data-title="Advice Body" data-show="GetAdviceBody" data-transition="slide">
<header data-role="header" id="adviceBodyNavbarHeader">
<div class="navHeader">
<a class="nav-button" data-view="adviceTitles" data-align="left">Back</a>
<span id="adviceTitle" class="navTitle"></span>
</div>
</header>
<ul id="advice-body" data-role="listview">
</ul>
</div>
Your selector is wrong. You try to select a html element called adviceBodyNavbarHeader.
What you want to do is this: $('#adviceBodyNavbarHeader').text(sessionStorage.getItem("catTitle"));
Hope it helps.

template insertion in a editor

Describing a scenario:
I am going through the code mentioned below.B asically I am trying to figure out how to program so that
when a user clicks on "Use Template" button , it gets inserted into an editor.
Page 1:
There are lot of templates present
When a user clicks on the "Use Template" button on , it gets inserted into an editor that is present in
the next page (Page 2).
Please find the code snippet below for the first two templates I am going through:
<div id="templatesWrap">
<div class="template" data-templatelocation="templateone" data-templatename="Template ONE" data-templateid="" >
<div class="templateContainer">
<span>
<a href="https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templateone&sHubId=&goalComplete=200" title="Use Template">
<img class="thumbnail" src="templatefiles/thumbnail_010.jpg" alt="templateone">
</a>
</span>
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
</div>
</div>
<div class="template" data-templatelocation="templatetwo" data-templatename="Template TWO" data-templateid="" >
<div class="templateContainer">
<span>
<a href="https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templatetwo&sHubId=&goalComplete=200" title="Use Template">
<img class="thumbnail" src="templatefiles/thumbnail_011.jpg" alt="templatetwo">
</a>
</span>
<div class="templateName">Template TWO</div>
<p>
Use Template
</p>
</div>
</div>
And so on ....
How does the link "https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templatetwo&sHubId=&goalComplete=200" is inserting the template into the editor which is located on the next page? I haven't understood the token part and lot's of ID's present in the link
which I think are thereason behind inserting the template.
Has anyone come across such link before? Please advise.
Thanks
MORE CLARIFICATIONS:
Thanks for your answer.It did help me somewhat. I have few more questions:
Basically, I am using TinyMCE 4.0.8 version as my editor. The templates, I am using are from here:
https://github.com/mailchimp/email-blueprints/blob/master/templates/2col-1-2-leftsidebar.html
Some questions based on "Tivie" answer.
1) As you can see in the code for "2col-1-2-leftsidebar.html " it's not defined inside <div> tags unlike you defined it in <div> tags. Do you think that I can still
use it using "2col-1-2-leftsidebar.html " name?
2)I believe,for explanation purpose, you have included
`"<div contenteditable="true" id="myEditor">replaced stuff</div>`
and
<button id="btn">Load TPL</button>
<script>
$("#btn").click(function() {
$("#myEditor").load("template.html");
});
</script>
in the same page. Am I right? ( I understand you were trying to make an educated guess here, hence
just asking :) )
In my case, I have a separate page, where I have written code for buttons just like you wrote in editor.html like the following:
<button id="btn">Load TPL</button>. My button is defined inside <div class="templateContainer">.
Also, my templates are defined in a separate folder. So, I will have to grab the content(HTML Template), from
that folder and then insert into TinyMCE 4.08 editor. (Looks like two step process). Could you elaborate
on how should I proceed here?
More Question As of Dec 27
I have modifier my code for the template as follows:
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
Please note, I have added an additional id attribute for the following purpose.
If I go by the answer mentioned in the Tivia's post, is the following correct?
<script>
$("#temp1").click(function() {
$("#sTextBody").load("FolderURL/template.html");
});
</script>
My editor is defined like the following on Page 2 (Editor Page).
<div class="field">
<textarea id="sTextBody" name="sTextBody" style="width:948px; max-width:948px; height: 70%"></textarea>
</div>
I am confused, like, the script tag I have defined is in Page 1 where I have defined all the template related code
and the Page 2(Editor) page is a different page. It's simply taking me to Editor page (Page 2) and hence not working.
Please advise where I am wrong.
Thanks
MORE QUESTIONS AS of Jan 2
The problem Iam facing is as follows. Basically, for first template , I have the following code.
Code Snippet #1 where "Use "Template" button is present:
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
And the function suggested in the answer is as follows:
Code Snippet #2 where Editor is present:
<script>
$("#temp1").click(function() {
$("#sTextBody").load("FolderURL/template.html");
});
</script>
Since, I believe I first need to reach to that page after user clicks on "Use Template" button, where the editor is located, I have defined Code Snippet #1 on Page 1 and have defined the Code Snippet #2 and <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> as the very first two script tags in the Page 2 ( Editor Page). But still when I click on "User Template" button on Page 1, it's just letting me to next page and not loading the template into the editor.
Am I doing something wrong here? Please advise.
P.S. The problem I feel is somehow the click function on Page 2 is not getting activated with the temp1 id button mentioned on Page 1.
Thanks
Well, one can only guess without having access to the page itself (and it's source code). I can, however, make an educated guess on how it works.
The URL params follows a pattern. First you have a token that is equal in all templates. This probably means the token does not have any relevance to the template mechanism itself. Maybe it's an authentication token or something. Not relevant though.
Then you have the template identification (templateOne, templateTwo, etc...) followed by a HubId that is empty. Lastly you have a goalComplete=200 which might correspond to the HTTP success code 200 (OK).
Based on this, my guess would be that they are probably using AJAX on the background, to fetch those templates from the server. Then, via JScript, those templates are inserted into the editor box itself.
Using JQuery, something like this is trivial. here's an example:
template.html
<div>
<h1>TEST</h1>
<span>This is a template</span>
</div>
editor.html
<!DOCTYPE HTML>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head>
<body>
<div contenteditable="true" id="myEditor">
replaced stuff
</div>
<button id="btn">Load TPL</button>
<script>
$("#btn").click(function() {
$("#myEditor").load("template.html");
});
</script>
</body>
</html>
Edit:
1) Well, since those templates are quite complex and include CSS, you probably want to keep them separated from you editor page (or the template's CSS will mess up your page's css).
However, since you're using TinyMCE, it comes with a template manager built in, so you probably want to use that. Check this link here http://www.tinymce.com/wiki.php/Configuration:templates for documentation.
2) I think 1 answers your question but, just in case, my method above works for any page in any directory, provided it lives on the same domain. Example:
<script>
$("#btn").click(function() {
$("#myEditor").load("someDirectory/template.html");
});
</script>
I recomend you check this page for the specifics on using TinyMCE http://www.tinymce.com/wiki.php/Configuration:templates
EDIT2:
Let me explain the above code:
$("#btn").click(function() { });
This basically tells the browser to run the code inside the brackets when you click the element with an id="btn"
$("#myEditor").load("someDirectory/template.html");
This is an AJAX request (check the documentation here). It grabs the contents of someDirectory/template.html and places them inside the element whose id="myEditor"

How to edit text for a link that does not have an ID using Javascript

I want to change the text of a link using javascript. The problem is this particular link does not have an id. I am unable to change the html, as this is a SharePoint page, and this particular link is created by a page layout, which I do not have access to. Using IE Developer Tools, I see that the HTML surrounding the link is this:
<span id="DeltaPlaceHolderPageTitleInTitleArea">
<span>
<a href="#ctl00_PlaceHolderPageTitleInTitleArea_ctl00_SkipLink">
<img width="0" height="0" style="border-width: 0px;" alt="Skip Navigation Links" src="" /></a>
<span>
<a title="State-Compliance" href="/sites/tax/Compliance/SitePages/State-Compliance.aspx">State-Compliance</a>
</span>
<a id="ctl00_PlaceHolderPageTitleInTitleArea_ctl00_SkipLink"></a>
</span>
The link I wish to change is the second one, the one with "State-Compliance" for the tooltip.
I looked at jQuery, and found I could use $('#DeltaPlaceHolderPageTitleInTitleArea').find("a").text("Test"); to change the text, but it changes the text of all three links. How can I change just the one? Do I need to iterate through the three, or is there an easier way of getting the link I wish to change?
Sorry if this is a stupid question, I'm a c# developer, and this is my first experience using javascript.
Let me know if you need more information.
Warren
Use .eq():
$('#DeltaPlaceHolderPageTitleInTitleArea').find("a").eq(1).text("Test");
jsFiddle example
How about this, using the attribute equals selector:
$('#DeltaPlaceHolderPageTitleInTitleArea a[title="State-Compliance"]')

Modal Window / foundation.reveal.js and passing a variable

Task Overview
I'm using the Code Igniter Framework to build a small client management system.
Part of the functionality would be to delete records from the database, before deleting I need to check with the user their okay to delete that record as a precaution. I'd like to do this via a modal window.
Frameworks I'm using
CodeIgniter MVC Framework (PHP, MYSQL)
Foundation HTML/CSS Boilerplate
Foundation's Javascript Libraries (In particular reveal.js)
What I would like to achieve
I'd like to have the user click on the delete link:
Delete
As you can see, the href tag is currently saying, go to the delete_domain function in the main class, and it's passing in the clients ID into the URL, this is used of course on the otherside of the application to delete the record that matches that ID.
Further on in the tag we have:
data-reveal-id="deleteModal"
This refers to the same [id=deletemodal] found in the modal window div that has to reside at the bottom of the page just before the closing body tag.
This is the DIV for the Modal window that resides at the bottom of the page?
<div id="deleteModal" class="reveal-modal small">
<h2>Are you sure you want to DELETE?</h2>
<p class="lead">Random Text</p>
<a href="" ></a>
<a class="close-reveal-modal">×</a>
</div>
The Issue
I'm not really sure if or how it will work, because at the moment the delete link is inside a table row, each one of these rows is generated by a foreach function, so they're multiple of these inside the DOM each with a different /$clientID value.
If I could I'd like to pass that value to a modal window, then of course to the option to finally delete the row.
Can anyone help?
You can grab the data you want from the pressed button and throw it in the modal. There are probably a few ways to do it; here's one of them: http://jsfiddle.net/b37s3/
Delete
<div id="deleteModal" class="reveal-modal">
<h2>Are you sure you want to DELETE?</h2>
<p class="lead">Random Text</p>
<a class="deleteUrl" href="#"></a>
<a class="close-reveal-modal">×</a>
</div>
and js:
$(document).foundation();
$('a.deleteLink').click(function(){
var link = $('.deleteUrl');
$(link).attr('href', this.href);
$(link).html(this.href);
});
This will throw the href from the Delete button pressed into the modals' a href and as the links text.
