How Can I Pass String Variable to Anonymous Adobe View SDK Script?

I have a very basic knowledge of javascript and I have been unable to find a solution for my specific use of the Adobe View SDK API, though it seems like there should be a way. I am working on a web page to show newsletters in the pdf viewer. I have created a w3.css modal element so that I can open the viewer with a button click, and then close it with an "x" in the corner. The button click and the "x" toggle between the display style being "none" or "block". I really like this solution as it lets me use small images of the newsletters as the buttons, and it can be observed here: Test News Page by clicking on the newsletter image below May 4, 2020.
The ultimate goal I have is to be able to change the name of the pdf document that is opened in the viewer by clicking the button, which would need to pass a string variable called "docName" to the url called by the View SDK script. Since the url is already specified in the script inside my modal element when the page loads, here is the thinking I have for the additional script I need to pass my string variables: The button-click invokes my script (function changeName(docName)) and passes the "docName" variable. Then my script needs to pass this variable to the url in the View script (this is the part I don't know how to do), then refresh the page to reload my modal, and then change the display style of the modal to "block". I will copy the code for the View SDK below, showing where I need to insert the string variable with my document name:
<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
<script type="text/javascript">
document.addEventListener("adobe_dc_view_sdk.ready", function(){
var adobeDCView = new AdobeDC.View({clientId: "06179511ab964c9284f1b0887eca1b46", divId: "adobe-dc-view"});
adobeDCView.previewFile({
content:{location: {url: "https://www.shcsfarmington.org/" + docName + ".pdf"}},
metaData:{fileName: "Newsletter_050420.pdf"}
}, {embedMode: "FULL_WINDOW", defaultViewMode: "FIT_WIDTH"});
});
</script>
It seems like this should work, but with my limited knowledge of javascript I don't know how to pass this variable to the anonymous function in the View SDK code, and I would need as much detail and specifics in the syntax of the solution. I appreciate any help with this. Thanks.
EDIT: I thought maybe it would help to show the code for the function that I have come up with so far - then it could be examined and easier to debug and comment on:
<button id="CSS-050420" onclick="changeDoc('Newsletter_050420');"></button>
<script>
function changeDoc(docName) {
/* Need to pass docName to url=https://shcsfarmington.org/2020/news/Newsletter_" + newsDate + ".pdf"; */
window.location.reload(true);
document.getElementById('viewerModal').style.display='block';
}
</script>

I created a CodePen here for you to look at.
Basically, you'll load the first file when the SDK is ready but then you need to set the adobeDCView to null before recreating it.
function showPDF(url) {
adobeDCView = null;
fetch(url)
.then((res) => res.blob())
.then((blob) => {
adobeDCView = new AdobeDC.View({
// This clientId can be used for any CodePen example
clientId: "e800d12fc12c4d60960778b2bc4370af",
// The id of the container for the PDF Viewer
divId: "adobe-dc-view"
});
adobeDCView.previewFile(
{
content: { promise: Promise.resolve(blob.arrayBuffer()) },
metaData: { fileName: url.split("/").slice(-1)[0] }
},
{
embedMode: "FULL_WINDOW",
defaultViewMode: "FIT_PAGE",
showDownloadPDF: true,
showPrintPDF: true,
showLeftHandPanel: false,
showAnnotationTools: false
}
);
});
}
The link click even will pass the url to the PDF and then display it.

Controlling order of javascript execution PayPal Objects

I have a wordpress page. I have a number of links which go to PayPalObjects. PayPalObjects requires that you put code in the footer of the page with triggers to IDs for the elements which trigger a purchase. eg...
<a id="buysong_4" target="PPDGFrame" title="Click here to buy this song now.">$</a>
...and then in the footer of the page:
<script type="text/javascript">
var embeddedPPFlow1 = new PAYPAL.apps.DGFlow( {trigger : 'buysong_1'});
function MyEmbeddedFlow(embeddedFlow) {
this.embeddedPPObj = embeddedFlow;
this.paymentSuccess = function() {
this.embeddedPPObj.closeFlow();
window.location.href = "http://whatever.com/success/";
};
this.paymentCanceled = function() {
this.embeddedPPObj.closeFlow();
top.location.href = "http://whatever.com/fail/";
};
}
var myEmbeddedPaymentFlow1 = new MyEmbeddedFlow(embeddedPPFlow1);
</script>
Now, since I have dozens of such links, I wanted to avoid hard coding these ids into the content. eg...
<a class="buysong" target="PPDGFrame" title="Click here to buy this song now.">$</a>
So I added the following jQuery:
jQuery('.buysong').each(function(index, element) {
jQuery(this).attr('id', 'buysong_' + (index+1) );
});
The rendered page correctly adds the ID attribute to each link, BUT the PayPal js does not trigger properly. IOW: I have to 'hardcode' the ids into the page. This makes me think that the jQuery is firing -after- the PayPal script.
So... how do I 'tell' the PayPalObjects script to only execute -after- the jQuery has assigned the IDs? OR... even if I accomplished that, would it -still- not work because assigning the ID attr. dynamically isn't reliable for what I want to do?
TIA,

How to update bootstrap popover text?

I am using bootstrap-popover to show a message beside an element.
If I want to show different text in the popover after the first time, the text does not change. Re instantiating the popover with new text does not overwrite.
See this js fiddle for a live example:
http://jsfiddle.net/RFzvp/1/
(The message in the alert and the message in the dom is inconsistent after the first click)
The documentation is a bit light on how to unbind: http://twitter.github.com/bootstrap/javascript.html#popovers
Am I using this wrong? The Any suggestions on how to work around?
Thanks

You can access the options directly using the jquery data closure dictionary like this:
$('a#test').data('bs.popover').options.content = 'new content';
This code should work fine even after first initializing the popover.

Hiya please see working demo here: http://jsfiddle.net/4g3Py/1/
I have made the changes to get your desired outcome. :)
I reckon you already know what you are doing but some example recommendations from my end as follows for sample: http://dl.dropbox.com/u/74874/test_scripts/popover/index.html# - sharing this link to give you idea for different link with different pop-over if you will see the source notice attribute data-content but what you wanted is working by the following changes.
Have a nice one and hope this helps. D'uh don't forget to up vote and accept the answer :)
Jquery Code
var i = 0;
$('a#test').click(function() {
i += 1;
$('a#test').popover({
trigger: 'manual',
placement: 'right',
content: function() {
var message = "Count is" + i;
return message;
}
});
$('a#test').popover("show");
});​
HTML
<a id="test">Click me</a>
​

just in-case anyone's looking for a solution that doesn't involve re-instantiating the popover and just want to change the content html, have a look at this:
$('a#test').data('popover').$tip.find(".popover-content").html("<div>some new content yo</div>")
Update: At some point between this answer being written and Bootstrap 3.2.0 (I suspect at 3.0?) this changed a little, to:
$('a#test').data('bs.popover').tip().find ............

Old question, but since I notice that the no answer provides the correct way and this is a common question, I'd like to update it.
Use the $("a#test").popover("destroy");-method. Fiddle here.
This will destroy the old popover and enable you to connect a new one again the regular way.
Here's an example where you can click a button to set a new popover on an object that already has a popover attached. See fiddle for more detail.
$("button.setNewPopoverContent").on("click", function(e) {
e.preventDefault();
$(".popoverObject").popover("destroy").popover({
title: "New title"
content: "New content"
);
});

The question is more than one year old, but maybe this would be usefull for others.
If the content is only changed while the popover is hidden, the easiest way I've found is using a function and a bit of JS code.
Specifically, my HTML looks like:
<input id="test" data-toggle="popover"
data-placement="bottom" data-trigger="focus" />
<div id="popover-content" style="display: none">
<!-- Hidden div with the popover content -->
<p>This is the popover content</p>
</div>
Please note no data-content is specified. In JS, when the popover is created, a function is used for the content:
$('test').popover({
html: true,
content: function() { return $('#popover-content').html(); }
});
And now you can change anywhere the popover-content div and the popover will be updated the next time is shown:
$('#popover-content').html("<p>New content</p>");
I guess this idea will also work using plain text instead of HTML.

On Boostrap 4 it is just one line:
$("#your-element").attr("data-content", "your new popover content")

You can always directly modify the DOM:
$('a#test').next(".popover").find(".popover-content").html("Content");
For example, if you want a popover that will load some data from an API and display that in the popover's content on hover:
$("#myPopover").popover({
trigger: 'hover'
}).on('shown.bs.popover', function () {
var popover = $(this);
var contentEl = popover.next(".popover").find(".popover-content");
// Show spinner while waiting for data to be fetched
contentEl.html("<i class='fa fa-spinner fa-pulse fa-2x fa-fw'></i>");
var myParameter = popover.data('api-parameter');
$.getJSON("http://ipinfo.io/" + myParameter)
.done(function (data) {
var result = '';
if (data.org) {
result += data.org + '<br>';
}
if (data.city) {
result += data.city + ', ';
}
if (data.region) {
result += data.region + ' ';
}
if (data.country) {
result += data.country;
}
if (result == '') {
result = "No info found.";
}
contentEl.html(result);
}).fail(function (data) {
result = "No info found.";
contentEl.html(result);
});
});

This assumes that you trust the data supplied by the API. If not, you will need to escape the data returned to mitigate XSS attacks.

Learn't from previous answers
let popOverOptions = {
trigger: 'click',
...
};
// save popOver instance
let popOver = $(`#popover-unique-id`).popover(popOverOptions);
// get its data
let popOverData = popOver.data('bs.popover');
// load data dynamically (may be with AJAX call)
$(`#popover-unique-id`).on('shown.bs.popover', () => {
setTimeout(() => {
// set content, title etc...
popOverData.config.content = 'content/////////';
// updata the popup in realtime or else this will be shown next time opens
popOverData.setContent();
// Can add this if necessary for position correction:
popOver._popper.update();
}, 2000);
});
This way we can update popover content easily.
There's another way using destroy method.
http://jsfiddle.net/bj5ryvop/5/

Bootstrap 5.0 update
let popoverInstance = new bootstrap.Popover($('#element'));
And then:
popoverInstance._config.content = "Hello world";
popoverInstance.setContent();
(Caution: it will update popover content globally, so if you have multiple open popovers then they all will be updated with "Hello world")

I found Bootstrap popover content cannot changed dynamically which introduces the setContent function. My code (hopefully helpful to someone) is therefore:
(Noting that jquery data() isn't so good at setting as it is getting)
// Update basket
current = $('#basketPopover').data('content');
newbasket = current.replace(/\d+/i,parseInt(data));
$('#basketPopover').attr('data-content',newbasket);
$('#basketPopover').setContent();
$('#basketPopover').$tip.addClass(popover.options.placement);

if jQuery > 4.1 use
$("#popoverId").popover("dispose").popover({
title: "Your new title"
content: "Your new content"
);

Bootstrap 5.1
I tried about 8 different ways to change the content for my Bootstrap 5.1 project, but none worked. I could see the values in the underlying popover object and could change them, but they didn't show on the page.
I got it going by first using the Bootstrap Popover's selector option, which the docs don't explain that well, but basically amounts to putting a watch on the page, so if new popover elements are added to the page (with the selector) they will become popovers automatically.
$(function() {
// set up all popovers
new bootstrap.Popover(document.body, {selector: 'has-popover');
})
then in my ajax call where some different content has been fetched, I remove the existing popover div, change the attribute with the text, and add it again:
var $pop = $('#pop_id1234')
var html = $pop[0].outerHTML // save the HTML
$pop.remove()
var $new = $(html).attr('data-bs-content',popoverText) // data('bs-content') becomes bsContent which won't work
$('#pop-container').append($new)

Javascript - how do I minimise this code example?

a quick question.
At the moment I have 12 links on a page, and 12 corresponding javascript codes that run when a each button is clicked.
I know 100% there must be a method of having 1 javascript code and the link passing a variable to it, so I don't have to have 12 different codes.
EG. Here is a link I'm currently using:
Anatomical Pathology
And the Javascript function that is run when the link is clicked loads some html from a php script into a div which is previously defined as level2:
$('#button1').click(function() {
level2.load("http://hello/script.php?url=poodles");
});
What I'd really like to do is something like this with the link:
Anatomical Pathology
And the function something like this, so I only need the 1 function not 12:
$('#button1').click(function() {
level2.load("http://hello/script.php?url=' + passurl + '");
});
How do I go about getting the data from the link tag into javascript, and also how do I add this passed variable into the url I want the javascript to pull data in from?

passurl isn't standard attribute, you should use data-passurl
$('#button1').click(function() {
var passurl = $(this).data('passurl'); // or $(this).attr('data-passurl');
level2.load("http://hello/script.php?url=" + passurl);
});

Why don't you utilize your hash there...
Anatomical Pathology
In your script
$(".button").each(function() {
// get the hash and extract the part we want store it in this enclosure
var url = $(this).attr("href").replace(/^#\//, "");
// create a click handler that loads the url
$(this).click(function() {
level2.load("http://hello/script.php?url=" + url);
});
});
This also brings about the possibility to extrapolate from that so that a hash passed through the url can also operate the script loading...

You can use the rel attributte (or any data- attributes if your using HTML5 Doctype) to save your URL and add a class to the links you want to execute your callback.
Anatomical Pathology
Your Callback:
$('a.button').click(function() {
level2.load("http://hello/script.php?url=' + $(this).attr('rel') + '");
});

For a more extensible solution you could consider making a json structure for your urls:
var urls = [{
"poodle":{
"url":"http://hello/script.php?url=poodle",
"someOtherData":"data"
},
"otherDog":{
"url":"http://hello/script.php?url=otherDog",
"someOtherData":"data"
}
}];
You would store some sort of key somewhere in your HTML element:
Anatomical Pathology
Then you would leverage this data structure in your functional code:
$('a').click(function () {
var key = $(this).attr('rel');
level2.load(urls[key].url);
});

As per Stuie, add a class to the links so that you can target them all at once. However, I don't see the need to fool with the hash, and I wouldn't add a bunch of click events either. Just delegate once and you're done:
<div id="wrapper">
Poodles
Schnausers
</div>
and the JS:
$('#wrapper').delegate('a.button', 'click', function(e) {
e.preventDefault();
var passurl = $(this).attr("href");
level2.load("http://hello/script.php?url=" + passurl); // assuming "level2" is valid from elsewhere
});
Where I have "#wrapper" you would designate any unique selector that is an ancestor of all your links. It's an element that listens for clicks on the a.button elements within.

How do I use colorbox to show hidden divs on my page without hardcoding?

I'm using Colorbox to show the html content of hidden divs on my page. I can get this to work perfectly with the following:
$("a.colorbox").colorbox({width:"600px", inline:true, href:"#344"});
This will show the div with the ID of 344.
However, because I'm trying to build a scalable and dynamic page with WordPress, I want to be able to grab the ID of my divs through a function, rather than hard code them in the jquery call.
I modified Jack Moore's example:
$("a[rel='example']").colorbox({title: function(){
var url = $(this).attr('href');
return 'Open In New Window';
}});
so that it looks like this:
$(".colorbox").colorbox({width:"600px", inline:true, href:function(){
var elementID = $(this).attr('id');
return elementID;
}});
The problem with this is that the href property of the colorbox function is looking for a string with a # mark infront of the ID. I tried various ways of concatenating the # to the front of the function, including the # in the return value, and concatenating the # to the elementID variable. No luck.
I also tried using the syntax in Jack's example (with no luck) so that my return statement looked like this:
return "#'+elementID+'";
I think my basic question is: How do I use colorbox to show hidden divs on my page without hardcoding everything?
Thanks for your help,
Jiert

I didn't really like any of the answers given above. This is how I did it (similar but not quite the same).
I also fully commented it for people a bit new to Javascript and the colorbox plug in.
$(document).ready(function() { //waits until the DOM has finished loading
if ($('a.lightboxTrigger').length){ //checks to see if there is a lightbox trigger on the page
$('a.lightboxTrigger').each(function(){ //for every lightbox trigger on the page...
var url = $(this).attr("href"); // sets the link url as the target div of the lightbox
$(url).hide(); //hides the lightbox content div
$(this).colorbox({
inline:true, // so it knows that it's looking for an internal href
href:url, // tells it which content to show
width:"70%",
onOpen:function(){ //triggers a callback when the lightbox opens
$(url).show(); //when the lightbox opens, show the content div
},
onCleanup:function(){
$(url).hide(); //hides the content div when the lightbox closes
}
}).attr("href","javascript:void(0)"); //swaps the href out with a javascript:void(0) after it's saved the href to the url variable to stop the browser doing anything with the link other than launching the lightbox when clicked
//you could also use "return false" for the same effect but I proffered that way
})
}
});
And this is the html:
<a class="lightboxTrigger" href="#lightboxContent">Lightbox trigger</a>
<div id="lightboxContent" class="lightboxContent"> <!-- the class is just to make it easier to style with css if you have multiple lightboxes on the same page -->
<p>Lightbox content goes here</p>
</div>
I think it would work with multiple lightboxes on the one page but I haven't tested it with that.

I'm facing the same issue. What does your html look like? meaning, how did you structure your "divs"
Mine looks like this:
Javascript:
<script>
$(document).ready(function () {
$("a.colorbox").colorbox({ width: "50%", inline: true, href: function () {
var elementID = $(this).attr('id');
return "#" + elementID;
}
});
});
</script>
And the html looks like (I tried changing the display:none):
<a class='colorbox' href="#">Inline HTML</a>
<div style="display:none">
<div id="pop">
This data is to be displayed in colorbox
</div>
</div>

return "#" + elementID;
will have the desired effect as David says.

This is the way I got it to work
HTML: (taken from the example in one of the answers)
<a class="lightboxTrigger" href="#lightboxContent">Lightbox trigger</a>
<div id="lightboxContent" class="lightboxContent"> <!-- the class is just to make it easier to style with css if you have multiple lightboxes on the same page -->
<p>Lightbox content goes here</p>
</div>
Javascript:
$('a.lightboxTrigger').click(function(){
var ref = $(this).attr("href");
$.colorbox({ html: $(ref).html() });
$.colorbox.resize();
});
