angular Scope variable is not binding in to iframe - javascript

i am creating hidden iframe for printing some data, but my code is not working properly, i want to show some data in that iframe by using angular scope variable bellow is my code.
// print attached contract documnet
function print(imageData) {
var hiddenFrame = $('<iframe style="display: none"></iframe>').appendTo('body')[0];
hiddenFrame.contentWindow.printAndRemove = function () {
hiddenFrame.contentWindow.print();
$(hiddenFrame).remove();
};
$scope.testObj = 'testing';
var element = $compile('<div> {{testObj}} </div>')($scope);
// var element = $compile($('<div> <img ng-src="{{ vm.contractDetails.contractAttachment.imageSRC }}" class="img-thumbnail img-responsive img-height " style="height:500px;cursor:pointer;" /> </div>'))(printScope);
var htmlDocument = "<!doctype html>" +
"<html>" +
'<body onload="printAndRemove();">' +
element.html() +
'</body>' +
"</html>";
var doc = hiddenFrame.contentWindow.document.open("text/html", "replace");
doc.write(htmlDocument);
doc.close();
}
then output is not proper
$scope.testObj is not binding properly.

Short answer
You cannot pass $scope to iframe regards to your configuration.
From image, angular didn't load inside iframe
[EDIT 1]
If you want to pass base64 image to iframe you don't need angular.
Just call:
<iframe src="data:application/pdf;base64,BINARY_DATA"></iframe>
If you want to use ng-src instead, to get rid of cross domain problem use $sce service:
<iframe ng-src="{{someStuff}}"></iframe>
$scope.someFrame= $sce.trustAsResourceUrl("http://www.yourURL.com");
[EDIT 2]
<iframe src="{{value}}"> </iframe>
Controller
app.controller('ctrlRead', function ($scope, $sce) {
$scope.value= $sce.trustAsResourceUrl("data:image/gif;base64,R0lGODlhPQBEAPeoAJosM//AwO/AwHVYZ/z595kzAP/s7P+goOXMv8+fhw/v739/f+8PD98fH/8mJl+fn/9ZWb8/PzWlwv///6wWGbImAPgTEMImIN9gUFCEm/gDALULDN8PAD6atYdCTX9gUNKlj8wZAKUsAOzZz+UMAOsJAP/Z2ccMDA8PD/95eX5NWvsJCOVNQPtfX/8zM8+QePLl38MGBr8JCP+zs9myn/8GBqwpAP/GxgwJCPny78lzYLgjAJ8vAP9fX/+MjMUcAN8zM/9wcM8ZGcATEL+QePdZWf/29uc/P9cmJu9MTDImIN+/r7+/vz8/P8VNQGNugV8AAF9fX8swMNgTAFlDOICAgPNSUnNWSMQ5MBAQEJE3QPIGAM9AQMqGcG9vb6MhJsEdGM8vLx8fH98AANIWAMuQeL8fABkTEPPQ0OM5OSYdGFl5jo+Pj/+pqcsTE78wMFNGQLYmID4dGPvd3UBAQJmTkP+8vH9QUK+vr8ZWSHpzcJMmILdwcLOGcHRQUHxwcK9PT9DQ0O/v70w5MLypoG8wKOuwsP/g4P/Q0IcwKEswKMl8aJ9fX2xjdOtGRs/Pz+Dg4GImIP8gIH0sKEAwKKmTiKZ8aB/f39Wsl+LFt8dgUE9PT5x5aHBwcP+AgP+WltdgYMyZfyywz78AAAAAAAD///8AAP9mZv///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAKgALAAAAAA9AEQAAAj/AFEJHEiwoMGDCBMqXMiwocAbBww4nEhxoYkUpzJGrMixogkfGUNqlNixJEIDB0SqHGmyJSojM1bKZOmyop0gM3Oe2liTISKMOoPy7GnwY9CjIYcSRYm0aVKSLmE6nfq05QycVLPuhDrxBlCtYJUqNAq2bNWEBj6ZXRuyxZyDRtqwnXvkhACDV+euTeJm1Ki7A73qNWtFiF+/gA95Gly2CJLDhwEHMOUAAuOpLYDEgBxZ4GRTlC1fDnpkM+fOqD6DDj1aZpITp0dtGCDhr+fVuCu3zlg49ijaokTZTo27uG7Gjn2P+hI8+PDPERoUB318bWbfAJ5sUNFcuGRTYUqV/3ogfXp1rWlMc6awJjiAAd2fm4ogXjz56aypOoIde4OE5u/F9x199dlXnnGiHZWEYbGpsAEA3QXYnHwEFliKAgswgJ8LPeiUXGwedCAKABACCN+EA1pYIIYaFlcDhytd51sGAJbo3onOpajiihlO92KHGaUXGwWjUBChjSPiWJuOO/LYIm4v1tXfE6J4gCSJEZ7YgRYUNrkji9P55sF/ogxw5ZkSqIDaZBV6aSGYq/lGZplndkckZ98xoICbTcIJGQAZcNmdmUc210hs35nCyJ58fgmIKX5RQGOZowxaZwYA+JaoKQwswGijBV4C6SiTUmpphMspJx9unX4KaimjDv9aaXOEBteBqmuuxgEHoLX6Kqx+yXqqBANsgCtit4FWQAEkrNbpq7HSOmtwag5w57GrmlJBASEU18ADjUYb3ADTinIttsgSB1oJFfA63bduimuqKB1keqwUhoCSK374wbujvOSu4QG6UvxBRydcpKsav++Ca6G8A6Pr1x2kVMyHwsVxUALDq/krnrhPSOzXG1lUTIoffqGR7Goi2MAxbv6O2kEG56I7CSlRsEFKFVyovDJoIRTg7sugNRDGqCJzJgcKE0ywc0ELm6KBCCJo8DIPFeCWNGcyqNFE06ToAfV0HBRgxsvLThHn1oddQMrXj5DyAQgjEHSAJMWZwS3HPxT/QMbabI/iBCliMLEJKX2EEkomBAUCxRi42VDADxyTYDVogV+wSChqmKxEKCDAYFDFj4OmwbY7bDGdBhtrnTQYOigeChUmc1K3QTnAUfEgGFgAWt88hKA6aCRIXhxnQ1yg3BCayK44EWdkUQcBByEQChFXfCB776aQsG0BIlQgQgE8qO26X1h8cEUep8ngRBnOy74E9QgRgEAC8SvOfQkh7FDBDmS43PmGoIiKUUEGkMEC/PJHgxw0xH74yx/3XnaYRJgMB8obxQW6kL9QYEJ0FIFgByfIL7/IQAlvQwEpnAC7DtLNJCKUoO/w45c44GwCXiAFB/OXAATQryUxdN4LfFiwgjCNYg+kYMIEFkCKDs6PKAIJouyGWMS1FSKJOMRB/BoIxYJIUXFUxNwoIkEKPAgCBZSQHQ1A2EWDfDEUVLyADj5AChSIQW6gu10bE/JG2VnCZGfo4R4d0sdQoBAHhPjhIB94v/wRoRKQWGRHgrhGSQJxCS+0pCZbEhAAOw==");

DEMO Fiddle

instead writing
var doc = hiddenFrame.contentWindow.document.open("text/html", "replace");
doc.write(htmlDocument);
doc.close();
Use ngBindHtml
$scope.myHtml = $sce.trustAsHtml(data.html);
In the hiddenFrame,add one placeHolder variable {{myHtml}}.
It will Worke.

Getting compiled html from template in AngularJS

I must confess that it's not easy to find some basic and easy to understand guide about compiling templates in AngularJS.
Here is the deal:
In my main html-page I have this:
<div>
<div data-ng-include="'./views/testTemplate.html'"></div>
</div>
<div>
<input type=button ng-click="func()" />
</div>
testTemplate.html contains this:
hello {{myname}}
Im my javascript-controller I have this:
$scope.myname = 'max';
Now, when I view the page I see the text "hello max".
Im my javascript-controller I also have this:
$scope.func = function(){
var newScope = $scope.$new();
var newElem = '<ng-src><div ng-include="\'./views/testTemplate.html\'" ></div></ng-src>';
$compile(newElem)(newScope);
console.log('newElem');
console.log(newElem);
});
In the console I can see this:
newElem
<ng-src><div ng-include="'./views/testTemplate.html'" ></div></ng-src>
So, the template is not getting compiled? What am I missing?
***************EDIT***************
The thing is that Im trying to print to console the content of the new element because it needs to be mailed. So I need to send a mail with the compiled content from the template.
Having looked at the answers below, I now have this:
var newElem = '<ng-src><div ng-include="\'./views/testTemplate.html\'" ></div></ng-src>';
var compiledElem = $compile(newElem)(newScope);
console.log('compiledElem[0]');
console.log(compiledElem[0]);
If I use this:
$window.location.href = 'mailto:mailmail.com?subject=sub&body=' + compiledElem[0].innerHTML;
then the body of the mail contains this (uncompiled template):
<!-- ngInclude: './views/matching/testTemplate.html' -->
If I use this:
$window.location.href = 'mailto:mailmail.com?subject=sub&body=' + compiledElem[0];
then the body of the mail contains this:
[object HTMLElement]
So none of them is showing the html-content in the mail I want to send. I know its not exactly the original question, but it was a part of the issue.
I think the variable 'newElem' is not modified by the $compile command. It has a return value which you should use.
var compiledElement = $compile(newElem)(newScope);
console.log('compiledElement');
console.log(compiledElement);
You are missing adding your HTML to the DOM.
$scope.func = function(){
var newScope = $scope.$new();
var newElem = '<ng-src><div ng-include="\'./views/testTemplate.html\'" ></div></ng-src>';
//Append to DOM
document.querySelector('#some-id').append($compile(newElem)(newScope));
console.log('newElem');
console.log(newElem);
});
In my example I'm using document.querySelector that is raw js. But we can use the $element service, or if we are in a directive's link function, it receives a param representing the current element where the directive is being applied.
EDIT:
If you want to send your compiled HTML in an email, then, you will need to wait until all the $digest finish to compile your template.
$scope.func = function(){
var newScope = $scope.$new();
var newElem = angular.element('<ng-src><div ng-include="\'./views/testTemplate.html\'" ></div></ng-src>');
$compile(newElem)(newScope);
$timeout(function(){
$window.location.href = 'mailto:mailmail.com?subject=sub&body=' + newElem.html();
//console.log('newElem');
//console.log(newElem.html());
});
});
Create your template using angular.element, use $timeout to wait until the end and then use newElem.html();.

Can't update iframe content with jquery

iframe is loaded dynamically into container div inside function.
With cc.text(content); I try to update #code content.
I check changed text in runtime, it's updated but on screen value remains the same.
I am not a javascript pro, so any comments are welcome:
function ShowEditor(content) {
var url = "XmlEditor/Editor.htm";
slHost.css('width', '0%');
jobPlanContainer.css('display', 'block');
frame = $('<iframe id="' + jobPlanIFrameID + '" src="' + url + '" class="frame" frameborder="0" />');
frame.appendTo(jobPlanIFrameContainer);
$(frame).load(function () {
var ifr = frame[0];
var doc = ifr.contentDocument || ifr.contentWindow.document;
var jdoc = $(doc);
var cc = jdoc.contents().find("#code");
// var tst = cc.text();
// alert(tst);
cc.text(content);
});
}
I get the text in commented code, but fail to update #code content.
iframe holds the following html where I omit details inside head and script:
<!doctype html>
<html>
<head></head>
<body>
<form>
<textarea id="code" name="code">some texts</textarea>
</form>
</body>
</html>
Your XML editor doesn't read more than once what's in the textarea.
A simple solution would be to generate in javascript the iframe content with the desired textarea content instead of loading it and then try to change the textarea content.
In fact (depending on the capacities of your XML Editor), you probably can do that directly in a generated text area instead of using a whole iframe to do it.

Capture incoming URL Parameters, then pass to iFrame Src with Javascript

So trying to figure out how to do this with window.location in Javascript. I'm sending users to our site with an appended URL with a Google Analytics code that I need to pass to an iframe src on that page. I'd assume Javascript could do this (note - I cannot use PHP)...
This is what I want to do:
I'd send users to the page with all the campaign data in tact. For example a user would click on this link:
http://www.xyz.com/index.html?utm_source=Facebook&utm_campaign=Facebook+May&utm_medium=click
They would be directed to that page, that then has this iFrame on it. The code on the store side would need to pick up utm_source, utm_campaign, utm_medium and include these parts in the IFRAME SRC So this bit:
<iframe height="960px" frameborder="0" scrolling="no" width="958px" src="http://www.abc.com/minis"></iframe>
now becomes:
<iframe height="960px" frameborder="0" scrolling="no" width="958px" src="http://www.abc.com/minis?utm_source=Facebook&utm_campaign=Facebook+May&utm_medium=click"></iframe>
Any javascript suggestions would be greatly appreciated. Note - I cannot use PHP.
UPDATE:
Got this to work!! Yay, but now I need to edit it a bit:
So say the appended url that was clciked was this:
http://abc.com/index.html?apple&orange&peach
and I need the iframe src to be this
http://xyz.com/minis?orange&peach
I moved a few things around in the script, but is now only grabbing orange and not the other & attribute (peach). please advise if there is a better way to work (without have all the params and then depending on what link comes in, some of the & will be undefined:
<body>
<script type="text/javascript">
$(function() {
var loc = window.location.toString(),
params = loc.split('&')[1],
params2 = loc.split('&')[2],
params3 = loc.split('&')[3],
params4 = loc.split('&')[4],
params5 = loc.split('&')[5],
params6 = loc.split('&')[6],
iframe = document.getElementById('myIframe');
alert(iframe.src);
iframe.src = iframe.src + '?' + params + '&' + params2 + '&' + params3 + '&' + params4+ '&' + params5;
alert(iframe.src);
});
</script>
<iframe id="myIframe" src="http://www.xyz.com/minis"></iframe>
</body>
This little snippet should do, here all you have to do is grab the bit after ? as a string and append it to the iframe source.
var loc = window.location.toString(),
params = loc.split('?')[1],
iframe = document.getElementById('myIframe');
iframe.src = iframe.src + '?' + params;​​​​​​​​​​​​​​​​
Just use window.location.search.
const iframe = document.getElementById('frame');
iframe.src = iframe.src + window.location.search;​​​​​​​​​​​​​​​​

How can i rerender Pinterest's Pin It button?

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.
Project: https://github.com/onassar/JS-Pinterest
Raw: https://raw.github.com/onassar/JS-Pinterest/master/Pinterest.js
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>

Passing javascript variable from iframe to URL

Lets say I have a function like this:
<script type="text/javascript">
function ReturnURL()
{
var url = document.URL;
var url2 = url.split("=");
var urlID = url2[url2.length-1];
//window.open('http://localhost/POSkill/skillshow.aspx?user_id =' + urlID);
return urlID;
}
</script>
And I also have iframe in my html file which is something like below:
<iframe id="showSkill" scrolling="yes" src="http://localhost/POSkill/skillshow.aspx?user_id = ReturnURL()" height="350" runat="server" ></iframe>
Now all I want to do is to send the urlID value of javasrcipt as the user_id value in iframe. I have tried by using user_id = ReturnURL() but its not working.
How can I do this?
Thanks in Advance.
I answered something very similar at enter link description here
The answer is that you must set the "src" value on the JS rendering.
This means that somewhere in your javascript you should have the following code
...
document.getElementById("showSkill").src="http://localhost/POSkill/skillshow.aspx?user_id =" + ReturnURL()
...
This should work just fine.
