there are many ways to reach your goal. As you didn't explain your need explicitly, I just provide a simple example:
<script type='text/javascript' charset='utf-8'>
var iframe = document.createElement('iframe');
document.body.appendChild(iframe);
iframe.src = 'URL OF CONTENT YOU WANT TO PROVIDE';
iframe.width = 'THE WIDTH YOU WANT';
iframe.height = 'THE HEIGHT YOU WANT';
</script>
modify the code according to your need
escape this code in your html
have fun with your awesome embedded widget!

How To Create Embed With Javascript in .cs
Note: localhost:3197/website/js/embed/form.js'; // give your js path
FormBuilder(921,'MjEzNjkxMjU='); in this method first parameter give your form height and second your form name or Id. there Id is encoded format
StringBuilder sb = new StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("(function(d, t) { var s = d.createElement(t), options = {");
sb.Append("'async':true };");
sb.Append("s.src = ('https:' == d.location.protocol ? 'https://' : 'http://') + 'localhost:3197/website/js/embed/form.js';");
sb.Append("s.onload = s.onreadystatechange = function() {");
sb.Append("var rs = this.readyState; if (rs) if (rs != 'complete') if (rs != 'loaded') return;");
sb.Append("try { frm = new FormBuilder("+Form Height+",'"+FormId+"');frm.initialize(options);frm.display(); }");
sb.Append("catch (e) {}};");
sb.Append("var scr = d.getElementsByTagName(t)[0], par = scr.parentNode; par.insertBefore(s, scr);");
sb.Append("})(document, 'script');</script>");
txtjavascript.Value = sb.ToString(); // text box name
After Create embed script Simple and Easy Way Paste this script where you want to show in other page after that
(function(d, t) { var s =
d.createElement(t), options = {'async':true }; s.src = ('https:' ==
d.location.protocol ? 'https://' : 'http://') +
'localhost:3197/website/js/embed/form.js'; s.onload =
s.onreadystatechange = function() {var rs = this.readyState; if (rs)
if (rs != 'complete') if (rs != 'loaded') return; try { frm = new
FormBuilder(921,'MjEzNjkxMjU='); frm.initialize(options);
frm.display(); }catch (e) {}}; var scr =
d.getElementsByTagName(t)[0], par = scr.parentNode;
par.insertBefore(s, scr);})(document, 'script');
After That in your js file Create fuction like this and create iFrame ans create querystring where you fetch the form from database.
function FormBuilder(fHeight, formid) {
var iframe = document.createElement('iframe');
iframe.style = "height:" + fHeight + "px; width:100%; border:none";
iframe.setAttribute('allowTransparency', true);
iframe.frameBorder = "0";
iframe.scrolling = "no";
iframe.src = "http://localhost:3197/form/show-form?id="+ formid;
document.body.appendChild(iframe);
}

Capture MVC View from controller

How can I get the view from the controller? I am trying to convert the page to an image and using the webclientPrint to send the image to a thermal printer.
I can not use window.print(); because the thermal printer may not accept the data and I also don't want to show the printer dialog to the user also.
Review
I want to capture whole web page and convert it to an image.
function Printlabel() {
debugger
if (navigator.appName == "Microsoft Internet Explorer") {
var PrintCommand = '<object ID="PrintCommandObject" WIDTH=0 HEIGHT=0 CLASSID="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></object>';
document.body.insertAdjacentHTML('beforeEnd', PrintCommand);
PrintCommandObject.ExecWB(6, -1); PrintCommandObject.outerHTML = "";
}
else {
var contents = document.getElementById("PrintArea").innerHTML;
var frame1 = document.createElement('iframe');
frame1.name = "frame1";
frame1.style.position = "absolute";
frame1.style.top = "-1000000px";
document.body.appendChild(frame1);
var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document : frame1.contentDocument;
frameDoc.document.open();
frameDoc.document.write('<html><head><title></title>');
frameDoc.document.write('<link rel="stylesheet" type="text/css" href="/Styles/labelStyle.css" media="print">');
frameDoc.document.write('</head><body>');
frameDoc.document.write(contents);
frameDoc.document.write('</body></html>');
frameDoc.document.close();
setTimeout(function () {
window.frames["frame1"].focus();
window.frames["frame1"].print();
document.body.removeChild(frame1);
}, 500);
}
setTimeout("window.open('', '_self', ''); window.close();", 5000);
return false;
}
Yes you can, pass the ActionResult from controller and getting back html from the view as a string, with this method :
private string RenderActionResultToString(ActionResult result)
{
// Create memory writer.
var sb = new StringBuilder();
var memWriter = new StringWriter(sb);
// Create fake http context to render the view.
var fakeResponse = new HttpResponse(memWriter);
var fakeContext = new HttpContext(System.Web.HttpContext.Current.Request,
fakeResponse);
var fakeControllerContext = new ControllerContext(
new HttpContextWrapper(fakeContext),
this.ControllerContext.RouteData,
this.ControllerContext.Controller);
var oldContext = System.Web.HttpContext.Current;
System.Web.HttpContext.Current = fakeContext;
// Render the view.
result.ExecuteResult(fakeControllerContext);
// Restore old context.
System.Web.HttpContext.Current = oldContext;
// Flush memory and return output.
memWriter.Flush();
return sb.ToString();
}

Disqus in Ionic APP

I am trying to implement disqus commments in my ionic app. I know I have to host it on the domain its setup for which I believe I have configured correctly. Any assistance will be welcomed
Here is the code in my app.js for the ionic app
$scope.showComments = function () {
$scope.currentView = "comments";
//loadComments(params["shortname"], params["url"], params["title"], params["identifier"]);
//
var disqus_title = "Venue 1";
var disqus_identifier = '/venue/' + $stateParams.id;
var disqus_url = 'liverpool.li/venue/' + $stateParams.id;
var url = "http://liverpool.li/app/disqus.html?";
$scope.url = url + "shortname=liverpoolli&url=" + encodeURIComponent(disqus_url) +
"&title=" + encodeURIComponent(disqus_title) + "&identifier=" + encodeURIComponent(disqus_identifier);
$scope.url = $sce.trustAsResourceUrl($scope.url);
};
$scope.$on("$destroy", function () {
if ($scope.lastScriptElm && $scope.lastScriptElm.parentNode) {
$scope.lastScriptElm.parentNode.removeChild($scope.lastScriptElm);
$scope.lastScriptElm = null;
}
});
And the page it points to (disqus.html) located on my domain
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
</head>
<body>
<div id="disqus_thread"></div>
<script type="text/javascript">
var params;
var disqus_url;
var disqus_title;
var disqus_shortname;
var disqus_identifier;
window.onload = function () {
var match,
pattern = /\+/g,
search = /([^&=]+)=?([^&]*)/g,
decode = function (s) { return decodeURIComponent(s.replace(pattern, " ")); },
query = window.location.search.substring(1);
params = {};
while (match = search.exec(query))
params[decode(match[1])] = decode(match[2]);
if (params["shortname"] === undefined || params["url"] === undefined || params["title"] === undefined) {
alert("Required arguments missing");
}
else {
loadComments(params["shortname"], params["url"], params["title"], params["identifier"]);
}
};
function loadComments(shortname, url, title, identifier) {
disqus_url = url;
disqus_title = title;
disqus_shortname = shortname;
if (identifier !== undefined)
disqus_identifier = identifier;
else
disqus_identifier = "";
(function() {
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = false;
dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js';
(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
})();
}
</script>
<noscript>Please enable JavaScript to view the comments powered by Disqus.</noscript>
blog comments powered by <span class="logo-disqus">Disqus</span>

I get the following error
we were unable to load disqus. if you are a moderator please see our
troubleshooting guide.
It looks like you're almost there. The only issue I see is the disqus_url variable must also include the protocol to be valid. Try using this line instead:
var disqus_url = 'http://liverpool.li/venue/' + $stateParams.id;

Hide Search Engine ID for Google Custom Search Element API 2.0

I am implementing Google Custom Search Element API 2.0 in an ASP.NET MVC project. In the documentation they require that the following javascript is included in the view, with the <gcse:search> element following.
<script>
(function() {
var cx = 'xxxxxxxx:yyyyyyyy';
var gcse = document.createElement('script');
gcse.type = 'text/javascript';
gcse.async = true;
gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
'//www.google.com/cse/cse.js?cx=' + cx;
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(gcse, s);
})();
</script>
<gcse:search></gcse:search>
However, the search engine id is visible on the line:
var cx = 'xxxxxxxx:yyyyyyyy';
In a browser, selecting View Source (or similar) allows the user to view the script and the search engine id.
How do I ensure that no-one can see my id?
I have found a way around this. By moving the Google script to its own function that takes the Search Engine Id as a parameter:
function buildSearchElement(cx)
{
var gcse = document.createElement("script");
gcse.type = "text/javascript";
gcse.async = true;
gcse.src = (document.location.protocol === "https:" ? "https:" : "http:") +
"//www.google.com/cse/cse.js?cx=" + cx;
var s = document.getElementsByTagName("script")[0];
s.parentNode.insertBefore(gcse, s);
};
I then call a method on my controller that returns the Search Engine Id upon page load. When this completes, the callback is the buildSearchElement function:
(function ()
{
var httpRequest = new XMLHttpRequest();
httpRequest.onreadystatechange = function()
{
if (httpRequest.readyState === 4 && httpRequest.status === 200)
{
buildSearchElement(httpRequest.responseText);
}
}
httpRequest.open("GET", "/GetSearchElementId");
httpRequest.send();
})();

Same disqus thread is loading for all articles

I have SPA pages that uses durandaljs and knockoutjs. Now I am going to implement a support of disqus plugin for my site.
When I added disqus I have found that the same comments is showing up for different pages with different URL (I used durandal for URL rewriting).
I guess that root of this issue is that my rewrote URL's are distinguished by full hashbang(#!)
The code is following:
var disqus_shortname = 'somename';
var disqus_identifier = context.id;
(function () {
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js';
(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
})();
if (typeof DISQUS != 'undefined') {
DISQUS.reset({
reload: true,
config: function () {
this.page.title = "title" + context.id;
this.page.identifier = context.id;
this.page.url = "http://localhost:23054/#!ideas/details/" + context.id;
debugger;
}
});
}
View:
<div id="disqus_thread"></div>
I hope somebody uses disqus comments with SPA pages and knows how to help me to solve this.
here's my solution:
var id = context.id;
disqus_shortname = 'somename',
disqus_identifier = id,
disqus_title = id,
disqus_url = "http://someurl.com/#!" + id;
if ($('head script[src="http://' + disqus_shortname + '.disqus.com/embed.js"]').length == 0) {
(function () {
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js';
(document.getElementsByTagName('head')[0]).appendChild(dsq);
})();
}
if (typeof DISQUS != "undefined") {
DISQUS.reset({
reload: true,
config: function () {
this.page.identifier = id;
this.page.url = "http://someurl.com/#!" + id;
}
});
}
I think the problem may be that your identifier isn't unique enough. From the Disqus documentation:
When Disqus-enabled pages are visited, Disqus uses this identifier to
determine the appropriate comment thread to load. If the appropriate
thread could not be found, a new thread is created.
I'm not sure what context.id is, but make sure that this is unique for each thread and unique enough for Disqus' purposes.

JS get and insert into <script>

I'm writing this code for an extension but It returns:
Origin chrome-extension://gjganecebobheilkbpmhmocibjckgidc is not allowed by Access-Control-Allow-Origin
var randomstring = '';var jsid = 0;
for (var i=0; i<20; i++) {
var rnum = Math.floor(Math.random() * "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz".length);
randomstring += "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz".substring(rnum,rnum+1);
}
function addS(file){
var xmlHttp = null;
xmlHttp = new XMLHttpRequest();
xmlHttp.open( "GET", file, false );
xmlHttp.send( null );
jsid = jsid + 1;
var s = document.createElement('script');
s.type = 'text/javascript';
// s.src = file;
s.innerHTML = xmlHttp.responseText;
s.async = "true";
s.id = randomstring+"_unique"+jsid;
s.className = randomstring;
document.head.appendChild(s);
}
addS('https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js');
addS('http://domain.com/functions.js'');
I would use jQuery but I can't because it breaks the source code of the page, what I want is to do the same as this, but in javascript and skipping that error
function addS(file){
jsid = jsid + 1;
$.get(file, function(data) {
var string = '<script type="text/javascript" async="true" id="'+randomstring+"_unique"+jsid+'" class="'+randomstring+'">'+data+'</script>';
$('head').append(string);
});
Additional Info
I'm gonna insert jquery.js and functions.js with an ID like this tags:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" async="true" id="AWhAXksocT6o6OrBxT28_unique1" class="AWhAXksocT6o6OrBxT28"></script>
<script type="text/javascript" src="http://domain.com/functions.js" async="true" id="AWhAXksocT6o6OrBxT28_unique2" class="AWhAXksocT6o6OrBxT28"></script>
with this code:
function addS(file){
jsid = jsid + 1;
var s = document.createElement('script');
s.type = 'text/javascript';
s.src = file;
s.async = true;
s.id = randomstring+"_unique"+jsid;
s.className = randomstring;
document.head.appendChild(s);
}
I need this ID (via var randomstring) to keep alive, that's the main problem because I will need to delete both after function ends but it returns
functions.js: Uncaught ReferenceError: randomstring is not defined using this code
$(document).ready(function(){
alert("Functions loaded");
//Do some functions....
$("."+randomstring).delete();
});
Thanks!
You can't perform a cross-domain ajax request unless the domain you are requesting from implements CORS.
What you are doing currently IS a cross-domain ajax request. If you instead do as Sirko suggested and request it by making the src of the script element you are appending the url to the ajax request, it will properly make the request.
function addS(file){
//var xmlHttp = null;
//xmlHttp = new XMLHttpRequest();
//xmlHttp.open( "GET", file, false );
//xmlHttp.send( null );
//jsid = jsid + 1;
var s = document.createElement('script');
s.type = 'text/javascript';
s.src = file;
//s.innerHTML = xmlHttp.responseText;
s.async = "true";
s.id = randomstring+"_unique"+jsid;
s.className = randomstring;
document.head.appendChild(s);
}
What is the purpose of this function? In what context is it used? What does it accomplish?
As far as I can see, you're just pasting the content of a file into the script tag.
So why not pass the file url directly to the src parameter of the script tag instead?
function addS( file ) {
var scriptEl = document.createElement( 'script' );
scriptEl.setAttribute( 'src', file ) ;
document.head.appenChild( scriptEl );
}
