Hello I am super new to building websites. Please excuse my lacking terminology!!
I have a website that has Wildcard sub-domains. It is using this script to pull the wildcard sub-domains usernames.
<p id="dist-info"></p>
<script src="https://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
return;
var get_data_url = 'https://backoffice.WEBSITE.com/api/v2/public/users/{username}';
$.getJSON(get_data_url, function( data ) {
var dist_info = "<p>"+data.response['first-name']+"</p>" +
"<p>"+data.response['last-name']+"</p>" +
"<p>"+data.response['distributor-id']+" "+data.response.email+"</p>" +
"<p>"+data.response['image-url']+"</p>" +
"<p>Phone: "+data.response.phone+"</p>";
$('#dist-info').html(dist_info);
});
});
</script>
Now I need to make a URL that will parse the username/user id out of the Wildcard Subdomain page. What code do I need to use?
For example
The URL is
USERNAME.WEBSITE.com/page/subpage/
I need to make this URL
backoffice.WEBSITE.com/page?sponsor-id=USERNAME
What do I need to do so that the username from the first page is parsed out and applied to the link of the second URL
You want to modify this JavaScript so it uses the subdomain instead of {username}?
$(document).ready(function() {
var get_data_url = 'https://backoffice.WEBSITE.com/api/v2/public/users/';
var hostname_parts = location.hostname.split('.');
var username = hostname_parts.shift();
// add username to the data URL
get_data_url += username;
// add username to some link on the website
var $aTag = $('#id-of-the-link');
var link_url = $aTag.attr('href');
link_url += username;
// set the new href attribute
$aTag.attr('href', link_url);
location.hostname gives you USERNAME.WEBSITE.com, split() splits it into parts separated by a dot. shift() takes the 1st element of this array (you could also use hostname_parts[0]) and with += you concatenate it to the URL.
The second example shows how to add the username at the end of a link like
click
Edit: added example for changing a href attribute
Okay, Stumped. I just use code to show possibilities to customers (am self-employed).
Trying to show get-selected-text-from-IE11-Browser. Don't need cross-Browser and expert stuff just yet (if customer goes ahead).
Have tried to write a javascript function to get the selected text from the browser. This has worked fine when called direct (put function into Console via F12 facility) and this returns the selection. But when calling from Context Menu HTM script it fails with the mentioned error. The code to get the selected text comes from another context menu script that works fine when all the code is in the one HTM script (cmGoogleMapSelection_1.htm). I was just trying to be a little more efficient with reuse and learn a little more myself. I will return to in-line code if I can't resolve the issue (with help from your marvellous selves).
Keep getting the following error reported in the HTM script :
The value of the property 'myGetSelectedText' is null or undefined, not a Function object.
Have read a number of posts and tried to ensure that I have covered their suggestions. Still stumped, any help appreciated.
The code, first the 'function', then the 'script'; both script file and function file are in the same local file folder (please excuse the Debug code - gulp):
fn_myGetSelectedText.js:
function myGetSelectedText(pDefault) {
var zDbug = 1;
var zDbugMsg = "Debug: ";
var zSelection = "";
if (zDbug) {alert(zDbugMsg + "Starting Function 'myGetSelectedText' from fn_myGetSelectedText.js");}
zSelection = "" + window.getSelection().toString();
if (zDbug) {alert(zDbugMsg + " Selection= '" + zSelection + "'");}
if (zSelection == "") {
zSelection = pDefault;
alert(zDbugMsg + "Null selection, using: " + zDefault + " !");
}
return zSelection;
}//EndOf: Function -----
cmGoogleMapSelection_2.htm:
<!-- saved from url=(0016)http://localhost -->
<script type="text/javascript" src="fn_myGetSelectedText.js"></script>
<script type="text/javascript">
//- zDbug: 0 = false = no messages; 1 = true = show messages -----
var zDbug = 1;
var zDbugMsg = "Debug: ";
if (zDbug) {alert(zDbugMsg + "Starting cmGoogleMap_Selection2.htm V14");}
//- Google Maps stem URL & default location -----
var zMaps = "http://maps.google.co.uk/maps?hl=en&q=";
var zDefault = "+London";
var zSelection = myGetSelectedText(zDefault); //- Error occurs here <<<<<<<<<<<
if (zDbug) {alert(zDbugMsg + " Selection= '" + zSelection + "'");}
//- Build Maps URL -----
var zGo = zMaps + zSelection;
//- Open new Maps window -----
if (zDbug) {alert(zDbugMsg + "Issuing Window.Open on URL: " + zGo);}
window.open(zGo, "_blank");
//- Close this window -----
window.close()
</script>
<!-- Just to put something into the main code window so I know which one it is -->
<style>
p {font-family: "Lucida Console"; color: Red; font-size: 16pt;}
</style>
<p> >>-- Map Selected Text Function --<< <br>
>>-- . . 'myGetSelectedText' . . --<< </p>
I am hoping like heck that I haven't missed a bracket somewhere - embarrassing!
Other stuff: Windows 10 Pro (fully updated); 64 bit IE11; just javascript; Compatibility View OFF; Registry Keys/Values pointing where they should (cloned from working version).
While browser downloads fn_myGetSelectedText.js file from the internet, it does not stop parsing other code in your HTML. There's concurrent downloading of assets going on while browser parses the DOM.
when browser reaches this line var zSelection = myGetSelectedText(); it does not see myGetSelectedText defined on the window object at that moment thus throws out error.
What you want to do is wrap your script/code in your HTML into DOMContentLoaded event and call it once page load completes.
<script>
document.addEventListener("DOMContentLoaded", function(event) {
console.log("DOM fully loaded and parsed");
});
</script>
reference: https://developer.mozilla.org/en-US/docs/Web/Events/DOMContentLoaded
My guess would be that in your called function, pDefault is undefined, because you aren't passing a variable when you do the call.
So, this line: var zSelection = myGetSelectedText();
Should become: var zSelection = myGetSelectedText(zDefault);
HTH,

I'm trying to get a webpage to open up a random image and text to go along with it. I will be using this to have different events posted on our library's front page. Pulling from different examples on the web I've gotten the basics to work fine with this.
var total_images = 2;
var random_number = Math.floor((Math.random()*total_images));
var random_img = new Array();
var random_text = [];
random_img[0] = "<a href = 'www.webpage.com'><img src='image_1.jpg' alt='Image'></a>";
random_text[0] = "<p>Here is some text</p>";
random_img[1] = "<a href = 'www.webpage2.com'><img src='image_2.jpg' alt='Image2'></a>";
random_text[1] = "<p>Here is some text2</p>";
document.write(random_img[random_number] + ' <br/><p id="myP">' + random_text[random_number] + 'dfsadf</p>');
function myFunction() {
document.getElementById("myP").style.font = "italic bold 20px arial,serif";
}
It works as hoped and on a refresh will display a new event picture and text. What I am having trouble with is I cannot get it to match the styles from the rest of our webpage. I've tried using functions to create a new id, regular html tags and just about anything I can pull from the web. Any time I add anything more to the random_text[] = "<p>codehere</p>"; than the usual <b> or <i> it breaks the page.
If I can change the fonts to match it would be perfect.
It will probably break the page because a <p> tag should not be put inside of another <p> tag. Try this for the document write:
document.write('<div id="myP">' + random_img[random_number] + ' <br/>' + random_text[random_number] + 'dfsadf</div>');
And the fonts could be modified using CSS in your HTML page:
<style type="text/css">
#myP p { font:20px arial,sans-serif; }
</style>
I have been trying to create a hyperlink using a variable defined earlier in the same function to append:
var NAMEVARIABLE = responseArray[i].Name;
var TITLE_Game = document.createElement("p");
TITLE_Game.className = "TITLE_Game";
TITLE_Game.innerHTML = "<a href='Game_NAMEVARIABLE.html'>Games</a>";
I have tried the following using the solution found here: Passing Javascript variable to <a href >
Games
But that didn't work. I then tried adding an ID:
<a id="link" href="Game_.html?propid=">Games</a>
And adding this to the script: document.links["link"].href += NAMEVARIABLE;
This didn't work either. These links are occuring within Isotope, which I've run into newbie-problems making sure my JSON data is loading before the script executes. That's all working now, but I'm not sure if the reason the above methods aren't working is because of a similar issue, or if they simply are not the proper way to go about this.
Any help is much appreciated. Thank you
first of all, try debug your variable :
var NAMEVARIABLE = responseArray[i].Name;
alert(NAMEVARIABLE);
is it returning the desired return value or not.
and then the second thing, in your first style of script, try this instead :
TITLE_Game.innerHTML = "<a href='Game_"+NAMEVARIABLE+".html'>Games</a>";
I assumed you have (static) html collection with game_[number_id].html format
and if it's so, you can try further with your second style of script, and change it to this :
Games
you need to learn further about javascript strings concatenation
Use string concatenation to build up your inner html string.
Example:
var nameVariable = 'Foo';
var innerHtmlText = nameVariable + 'bar';
$('#someElement').html(innerHtmlText);
The contents of someElement will then contain the text: 'Foobar';
You just need string concatenation. modify link's href onclick would be considered as spam in most modern browser.
<div id="result">
the result:
</div>
<script type="text/javascript">
var name = "foo_bar";
var url = "page.html?key=" + name; //or.. "page_" + name + ".html";
var link = 'link here';
$("#result").addClass("g_title");
$("#result").append(link);
</script>
This can be achieved by either (i.e. pure JS or jQuery) ways without much hassle. Suppose you have this <a> element with some href
<a id="Link" href="/collection/categories/">Games</a>
Pure JavaScript way:
window.onload = function() {
var link= document.getElementById('Link'),
url = link.href + responseArray[i].Name + '.html';
link.setAttribute('href', url);
}
Using Jquery:
$(function(){
var link= $('#Link'),
url = link.attr('href') + responseArray[i].Name + '.html';
link.attr('href', url);
});
I'm trying to create and manipulate the Pin It button after page load. When i change the button properties with js, it should be rerendered to get the functionality of pinning dynamically loaded images. So, does Pinterest have any method like Facebook's B.XFBML.parse() function?
Thanks...
Just add data-pin-build attribute to the SCRIPT tag:
<script defer
src="//assets.pinterest.com/js/pinit.js"
data-pin-build="parsePinBtns"></script>
That causes pinit.js to expose its internal build function to the global window object as parsePinBtns function.
Then, you can use it to parse links in the implicit element or all of the links on the page:
// parse the whole page
window.parsePinBtns();
// parse links in #pin-it-buttons element only
window.parsePinBtns(document.getElementById('pin-it-buttons'));
Hint: to show zero count just add data-pin-zero="1" to SCRIPT tag.
The best way to do this:
Remove the iframe of the Pin It button you want to manipulate
Append the html for the new button manipulating it as you wish
Realod their script - i.e. using jQuery:
$.ajax({ url: 'http://assets.pinterest.com/js/pinit.js', dataType: 'script', cache:true});
To render a pin-it button after a page has loaded you can use:
<a href="..pin it link.." id="mybutton" class="pin-it-button" count-layout="none">
<img border="0" src="//assets.pinterest.com/images/PinExt.png" width="43" height="21" title="Pin It" />
</a>
<script>
var element = document.getElementById('mybutton');
(function(x){ for (var n in x) if (n.indexOf('PIN_')==0) return x[n]; return null; })(window).f.render.buttonPin(element);
</script>
Assuming of course the assets.pinterest.com/js/pinit.js is already loaded on the page. The render object has some other useful methods like buttonBookmark, buttonFollow, ebmedBoard, embedPin, embedUser.
I built on Derrek's solution (and fixed undeclared variable issue) to make it possible to dynamically load the pinterest button, so it can't possibly slow down load times. Only tangentially related to the original question but I thought I'd share anyway.
at end of document:
<script type="text/javascript">
addPinterestButton = function (url, media, description) {
var js, href, html, pinJs;
pinJs = '//assets.pinterest.com/js/pinit.js';
//url = escape(url);
url = encodeURIComponent(url);
media = encodeURIComponent(media);
description = encodeURIComponent(description);
href = 'http://pinterest.com/pin/create/button/?url=' + url + '&media=' + media + '&description=' + description;
html = '<img border="0" src="http://assets.pinterest.com/images/PinExt.png" title="Pin It" />';
$('#pinterestOption').html(html);
//add pinterest js
js = document.createElement('script');
js.src = pinJs;
js.type = 'text/javascript';
document.body.appendChild(js);
}
</script>
in document ready function:
addPinterestButton('pageURL', 'img', 'description');//replace with actual data
in your document where you want the pinterest button to appear, just add an element with the id pinterestOption, i.e.
<div id="pinterestOption"></div>
hope that helps someone!
Here's what I did.
First I looked at pinit.js, and determined that it replaces specially-marked anchor tags with IFRAMEs. I figured that I could write javascript logic to get the hostname used by the src attribute on the generated iframes.
So, I inserted markup according to the normal recommendations by pinterest, but I put the anchor tag into an invisible div.
<div id='dummy' style='display:none;'>
<a href="http://pinterest.com/pin/create/button/?
url=http%3A%2F%2Fpage%2Furl
&media=http%3A%2F%2Fimage%2Furl"
class="pin-it-button" count-layout="horizontal"></a>
</div>
<script type="text/javascript" src="//assets.pinterest.com/js/pinit.js">
</script>
Then, immediately after that, I inserted a script to slurp up the hostname for the pinterest CDN, from the injected iframe.
//
// pint-reverse.js
//
// logic to reverse-engineer pinterest buttons.
//
// The standard javascript module from pinterest replaces links to
// http://pinterest.com/create/button with links to some odd-looking
// url based at cloudfront.net. It also normalizes the URLs.
//
// Not sure why they went through all the trouble. It does not work for
// a dynamic page where new links get inserted. The pint.js code
// assumes a static page, and is designed to run "once" at page creation
// time.
//
// This module spelunks the changes made by that script and
// attempts to replicate it for dynamically-generated buttons.
//
pinterestOptions = {};
(function(obj){
function spelunkPinterestIframe() {
var iframes = document.getElementsByTagName('iframe'),
k = [], iframe, i, L1 = iframes.length, src, split, L2;
for (i=0; i<L1; i++) {
k.push(iframes[i]);
}
do {
iframe = k.pop();
src = iframe.attributes.getNamedItem('src');
if (src !== null) {
split = src.value.split('/');
L2 = split.length;
obj.host = split[L2 - 2];
obj.script = split[L2 - 1].split('?')[0];
//iframe.parentNode.removeChild(iframe);
}
} while (k.length>0);
}
spelunkPinterestIframe();
}(pinterestOptions));
Then,
function getPinMarkup(photoName, description) {
var loc = document.location,
pathParts = loc.pathname.split('/'),
pageUri = loc.protocol + '//' + loc.hostname + loc.pathname,
href = '/' + pathToImages + photoName,
basePath = (pathParts.length == 3)?'/'+pathParts[1]:'',
mediaUri = loc.protocol+'//'+loc.hostname+basePath+href,
pinMarkup;
description = description || null;
pinMarkup = '<iframe class="pin-it-button" ' + 'scrolling="no" ' +
'src="//' + pinterestOptions.host + '/' + pinterestOptions.script +
'?url=' + encodeURIComponent(pageUri) +
'&media=' + encodeURIComponent(mediaUri);
if (description === null) {
description = 'Insert standard description here';
}
else {
description = 'My site - ' + description;
}
pinMarkup += '&description=' + encodeURIComponent(description);
pinMarkup += '&title=' + encodeURIComponent("Pin this " + tagType);
pinMarkup += '&layout=horizontal&count=1">';
pinMarkup += '</iframe>';
return pinMarkup;
}
And then use it from jQuery like this:
var pinMarkup = getPinMarkup("snap1.jpg", "Something clever here");
$('#pagePin').empty(); // a div...
$('#pagePin').append(pinMarkup);
I rewrote the Pinterest button code to support the parsing of Pinterest tags after loading AJAX content, similar to FB.XFBML.parse() or gapi.plusone.go(). As a bonus, an alternate JavaScript file in the project supports an HTML5-valid syntax.
Check out the PinterestPlus project at GitHub.
The official way to do this is by setting the "data-pin-build" attribute when loading the script:
<script defer="defer" src="//assets.pinterest.com/js/pinit.js" data-pin-build="parsePins"></script>
Then you can render your buttons dynamically like so:
// render buttons inside a scoped DOM element
window.parsePins(buttonDomElement);
// render the whole page
window.parsePins();
There is also another method on this site which lets you render them in JavaScript without the script tag.
Here is what i did.. A slight modification on #Derrick Grigg to make it work on multiple pinterest buttons on the page after an AJAX reload.
refreshPinterestButton = function () {
var url, media, description, pinJs, href, html, newJS, js;
var pin_url;
var pin_buttons = $('div.pin-it a');
pin_buttons.each(function( index ) {
pin_url = index.attr('href');
url = escape(getUrlVars(pin_URL)["url"]);
media = escape(getUrlVars(pin_URL)["media"]);
description = escape(getUrlVars(pin_URL)["description"]);
href = 'http://pinterest.com/pin/create/button/?url=' + url + '&media=' + media + '&description=' + description;
html = '<img border="0" src="http://assets.pinterest.com/images/PinExt.png" title="Pin It" />';
index.parent().html(html);
});
//remove and add pinterest js
pinJs = '//assets.pinterest.com/js/pinit.js';
js = $('script[src*="assets.pinterest.com/js/pinit.js"]');
js.remove();
js = document.createElement('script');
js.src = pinJs;
js.type = 'text/javascript';
document.body.appendChild(js);
}
});
function getUrlVars(pin_URL)
{
var vars = [], hash;
var hashes = pin_URL.slice(pin_URL.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
Try reading this post http://dgrigg.com/blog/2012/04/04/dynamic-pinterest-button/ it uses a little javascript to replace the pinterest iframe with a new button and then reloads the pinit.js file. Below is the javascript to do the trick
refreshPinterestButton = function (url, media, description) {
var js, href, html, pinJs;
url = escape(url);
media = escape(media);
description = escape(description);
href = 'http://pinterest.com/pin/create/button/?url=' + url + '&media=' + media + '&description=' + description;
html = '<img border="0" src="http://assets.pinterest.com/images/PinExt.png" title="Pin It" />';
$('div.pin-it').html(html);
//remove and add pinterest js
pinJs = $('script[src*="assets.pinterest.com/js/pinit.js"]');
pinJs.remove();
js = document.createElement('script');
js.src = pinJs.attr('src');
js.type = 'text/javascript';
document.body.appendChild(js);
}
Their pinit.js file, referenced in their "Pin it" button docs, doesn't expose any globals. It runs once and doesn't leave a trace other than the iframe it creates.
You could inject that file again to "parse" new buttons. Their JS looks at all anchor tags when it is run and replaces ones with class="pin-it-button" with their iframe'd button.
this works fine for me: http://www.mediadevelopment.no/projects/pinit/ It picks up all data on click event
I tried to adapt their code to work the same way (drop in, and forget about it), with the addition that you can make a call to Pinterest.init() to have any "new" buttons on the page (eg. ajax'd in, created dynamically, etc.) turned into the proper button.

As of June 2020, Pinterest updated the pin js code to v2. That's why data-pin-build might not work on
<script defer="defer" src="//assets.pinterest.com/js/pinit.js" data-pin-build="parsePins"></script>
Now it works on pinit_v2.js
<script async defer src="//assets.pinterest.com/js/pinit_v2.js" data-pin-build="parsePins"></script>
