ng2 PDF viewer not showing all pages

I am trying to show pdf document through ng2-pdfviewer. Following is code for viewing:
<pdf-viewer [page]="this.vars.page"
[src]="this.vars.pdfSrc"
[show-all]="true"
[original-size]="true"
></pdf-viewer>
It is working fine when show-all is set to false. But when I set it to true it skips first two pages and always starts from third page. Any help is appreciated.Thanks

I am suspicious that probably your error subsist in using the Typscript keyword this in a template. You don't need it in the template as it, because Angular will take care of making the binding between the class property (vars in your case) and the template, and 'this' is just not available.
So replace by the following:
<pdf-viewer [page]="vars.page"
[src]="vars.pdfSrc"
[show-all]="true"
[original-size]="true">
</pdf-viewer>
Please read about 'this'

DOJO Custom Dialog Box - does not parse template file

I am new to DOJO. I have a custom widget , which uses a template file for the dialog box contents.
I am extending dijit.Dialog in the script file.
dojo.declare(
"custom.credentials",
[dijit._WidgetBase, dijit._Templated,dijit._WidgetsInTemplateMixin,**dijit.Dialog**],
{
templatePath: dojo.moduleUrl("custom", "templates/credentials.html"),
....
....
postCreate: function() {
this.inherited(arguments);
alert(this.containerNode);
alert(this.mainDIV);
},
});
My Template test file looks like this
<div data-dojo-attach-point="mainDIV">
Login Dialog Box template here
</div>
For some reason, when I alert on this.mainDIV, I get 'undefined'. It does not read the template file. Also, this.containerNode gives me 'HTMLDIVElement', (parent dijit dialog DIV).
I am not able to figure out after a lot of trial error where exactly the issue is. Any help would be greatly appreciated.
Calling code
function opnPop(){
var pop= dijit.byId("customPopup");
pop.show();
}
<div dojoType="custom.credentials" id="customPopup"/>
Note : *When dijit.Dialog is not extended* it reads the template file without any problem, I.e, I am able to access this.mainDIV.innerHTML , that contains my own inner html contents.
Thank you.

If Dialog has to be sub-classed, then it must be the base class. Here, it seems that it is used as a mixin. Anyways, the problem is with the template that is used.
The template will be parsed and used by the code in Dialog. So, the template mentioned here has nothing but a div element with an attach point. There is no "containerNode" element (ie. attach point) and you are trying to access it in your js code, which will give error.
More important, the "titleBar" & "titleNode" elements are also missing form template, which will give errors while parsing the template. In order to avoid that, the code part that uses these elements need to be removed from js, to avoid error. So the widget creation will be successful. Try with the standard dijit.Dialog's template.
Add the data-dojo-attach-point="mainDIV" to the top level Dialog's div in the template.
In template, more things can be added, which won't cause any issues. But, if removed anything, will cause problem. If we are sub-classing a class/widget, we need to comply to the existing code.

Inline Editing But Instance Doesn't Exist

I have my own custom non-jQuery ajax which I use for programming web applications. I recently ran into problems with IE9 using TinyMCE, so am trying to switch to CKeditor
The editable text is being wrapped in a div, like so:
<div id='content'>
<div id='editable' contenteditable='true'>
page of inline text filled with ajax when links throughout the site are clicked
</div>
</div>
When I try to getData on the editable content using the examples in the documentation, I get an error.
I do this:
CKEDITOR.instances.editable.getData();
And get this:
Uncaught TypeError: Cannot call method 'getData' of undefined
So I figure that it doesn't know where the editor is in the dom... I've tried working through all editors to get the editor name, but that doesn't work-- no name appears to be found.
I've tried this:
for(var i in CKEDITOR.instances) {
alert(CKEDITOR.instances[i].name);
}
The alert is just blank-- so there's no name associated with it apparently.
I should also mention, that despite my best efforts, I cannot seem to get the editable text to have a menu appear above it like it does in the Massive Inline Editing Example
Thanks for any assistance you can bring.
Jason Silver
UPDATE:
I'm showing off my lack of knowledge here, but I had never come across "contenteditable='true'" before, so thought that because I was able to type inline, therefore the editor was instantiated somehow... but now I'm wondering if the editor is even being applied to my div.
UPDATE 2:
When the page is loaded and the script is initially called, the div does not exist. The editable div is sent into the DOM using AJAX. #Zee left a comment below that made me wonder if there is some other command that should be called in order to apply the editor to that div, so I created a button in the page with the following onclick as a way to test this approach: (adapted from the ajax example)
var editor,html='';config = {};editor=CKEDITOR.appendTo('editable',config, html );
That gives the following error in Chrome:
> Uncaught TypeError: Cannot call method 'equals' of undefined
> + CKEDITOR.tools.extend.getEditor ckeditor.js:101
> b ckeditor.js:252
> CKEDITOR.appendTo ckeditor.js:257
> onclick www.pediatricjunction.com:410
Am I headed in the right direction? Is there another way to programmatically tell CKEditor to apply the editor to a div?
UPDATE 3:
Thanks to #Reinmar I had something new to try. The most obvious way for me to test to see if this was the solution was to put a button above the content editable div that called CKEDITOR.inlineAll() and inline('editable') respectively:
<input type='button' onclick=\"CKEDITOR.inlineAll();\" value='InlineAll'/>
<input type='button' onclick=\"CKEDITOR.inline('editable');\" value='Inline'/>
<input type='button' onclick=\"var editor = CKEDITOR.inline( document.getElementById( 'editable' ) );\" value='getElementById'/>
This returned the same type of error in Chrome for all three buttons, namely:
Uncaught TypeError: Cannot call method 'equals' of undefined ckeditor.js:101
+ CKEDITOR.tools.extend.getEditor ckeditor.js:101
CKEDITOR.inline ckeditor.js:249
CKEDITOR.inlineAll ckeditor.js:250
onclick
UPDATE 4:
Upon further fiddling, I've tracked down the problem being related to json2007.js, which is a script I use which works with Real Simple History (RSH.js). These scripts have the purpose of tracking ajax history, so as I move forward and back through the browser, the AJAX page views is not lost.
Here's the fiddle page: http://jsfiddle.net/jasonsilver/3CqPv/2/

When you want to initialize inline editor there are two ways:
If element which is editable (has contenteditable attribute) exists when page is loaded CKEditor will automatically initialize an instance for it. Its name will be taken from that element's id or it will be editor<number>. You can find editors initialized automatically on this sample.
If this element is created dynamically, then you need to initialize editor on your own.
E.g. after appending <div id="editor" contenteditable="true">X</div> to the document you should call:
CKEDITOR.inline( 'editor' )
or
CKEDITOR.inlineAll()
See docs and docs.
You can find editor initialized this way on this sample.
The appendTo method has different use. You can initialize themed (not inline) editor inside specified element. This method also accepts data of editor (as 3rd arg), when all other methods (CKEDITOR.inline, CKEDITOR.replace, CKEDITOR.inlineAll) take data from the element they are replacing/using.
Update
I checked that libraries you use together with CKEditor are poorly written and cause errors you mentioned. Remove json2007.js and rsh.js and CKEditor works fine.

OK, so I have tracked down the problem.
The library I was using for tracking Ajax history and remembering commands for the back button, called Real Simple History, was using a script called json2007 which was intrusive and extended native prototypes to the point where things broke.
RSH.js is kind of old, and I wasn't using it to it's full potential anyway, so my final solution was to rewrite the essential code I needed for that, namely, a listener that watched for anchor (hash) changes in the URL, then parsed those changes and resubmitted the ajax command.
var current_hash = window.location.hash;
function check_hash() {
if ( window.location.hash != current_hash ) {
current_hash = window.location.hash;
refreshAjax();
}
}
hashCheck = setInterval( "check_hash()", 50 );
'refreshAjax()' was an existing function anyway, so this is actually a more elegant solution than I was using with Real Simple History.
After stripping out the json2007.js script, everything else just worked, and CKEditor is beautiful.
Thanks so much for your help, #Reinmar... I appreciate your patience and effort.

What exactly can cause an "HIERARCHY_REQUEST_ERR: DOM Exception 3"-Error?

How exactly does it relate to jQuery? I know the library uses native javascript functions internally, but what exactly is it trying to do whenever such a problem appears?

It means you've tried to insert a DOM node into a place in the DOM tree where it cannot go. The most common place I see this is on Safari which doesn't allow the following:
document.appendChild(document.createElement('div'));
Generally, this is just a mistake where this was actually intended:
document.body.appendChild(document.createElement('div'));
Other causes seen in the wild (summarized from comments):
You are attempting to append a node to itself
You are attempting to append null to a node
You are attempting to append a node to a text node.
Your HTML is invalid (e.g. failing to close your target node)
The browser thinks the HTML you are attempting to append is XML (fix by adding <!doctype html> to your injected HTML, or specifying the content type when fetching via XHR)

If you are getting this error due to a jquery ajax call $.ajax
Then you may need to specify what the dataType is coming back from the server. I have fixed the response a lot using this simple property.
$.ajax({
url: "URL_HERE",
dataType: "html",
success: function(response) {
$('#ELEMENT').html(response);
}
});

Specifically with jQuery you can run into this issue if forget the carets around the html tag when creating elements:
$("#target").append($("div").text("Test"));
Will raise this error because what you meant was
$("#target").append($("<div>").text("Test"));

This error can occur when you try to insert a node into the DOM which is invalid HTML, which can be something as subtle as an incorrect attribute, for example:
// <input> can have a 'type' attribute
var $input = $('<input/>').attr('type', 'text');
$holder.append($input); // OK
// <div> CANNOT have a 'type' attribute
var $div = $('<div></div>').attr('type', 'text');
$holder.append($div); // Error: HIERARCHY_REQUEST_ERR: DOM Exception 3

#Kelly Norton is right in his answer that The browser thinks the HTML you are attempting to append is XML and suggests specifying the content type when fetching via XHR.
It's true however you sometimes use third party libraries that you are not going to modify. It's JQuery UI in my case. Then you should provide the right Content-Type in the response instead of overriding the response type on JavaScript side. Set your Content-Type to text/html and you are fine.
In my case, it was as easy as renaming the file.xhtml to file.html - application server had some extension to MIME types mappings out of the box. When content is dynamic, you can set the content type of response somehow (e.g. res.setContentType("text/html") in Servlet API).

You can see these questions
Getting HIERARCHY_REQUEST_ERR when using Javascript to recursively generate a nested list
or
jQuery UI Dialog with ASP.NET button postback
The conclusion is
when you try to use function append, you should use new variable, like this example
jQuery(function() {
var dlg = jQuery("#dialog").dialog({
draggable: true,
resizable: true,
show: 'Transfer',
hide: 'Transfer',
width: 320,
autoOpen: false,
minHeight: 10,
minwidth: 10
});
dlg.parent().appendTo(jQuery("form:first"));
});
In the example above, uses the var "dlg" to run the function appendTo.
Then error “HIERARCHY_REQUEST_ERR" will not come out again.

I encountered this error when using the Google Chrome extension Sidewiki. Disabling it resolved the issue for me.

I'm going to add one more specific answer here because it was a 2 hour search for the answer...
I was trying to inject a tag into a document. The html was like this:
<map id='imageMap' name='imageMap'>
<area shape='circle' coords='55,28,5' href='#' title='1687.01 - 0 percentile' />
</map>
If you notice, the tag is closed in the preceding example (<area/>). This was not accepted in Chrome browsers. w3schools seems to think it should be closed, and I could not find the official spec on this tag, but it sure doesn't work in Chrome. Firefox will not accept it with <area/> or <area></area> or <area>. Chrome must have <area>. IE accepts anything.
Anyway, this error can be because your HTML is not correct.

I know this thread is old, but I've encountered another cause of the problem which others might find helpful. I was getting the error with Google Analytics trying to append itself to an HTML comment. The offending code:
document.documentElement.firstChild.appendChild(ga);
This was causing the error because my first element was an HTML comment (namely a Dreamweaver template code).
<!-- #BeginTemplate "/Templates/default.dwt.php" -->
I modified the offending code to something admittedly not bulletproof, but better:
document.documentElement.firstChild.nodeType===1 ? document.documentElement.firstChild.appendChild(ga) : document.documentElement.lastChild.appendChild(ga);

If you run into this problem while trying to append a node into another window in Internet Explorer, try using the HTML inside the node instead of the node itself.
myElement.appendChild(myNode.html());
IE doesn't support appending nodes to another window.

This ERROR happened to me in IE9 when I tried to appendChild an dynamically to a which already existed in a window A. Window A would create a child window B. In window B after some user action a function would run and do an appendChild on the form element in window A using window.opener.document.getElementById('formElement').appendChild(input);
This would throw an error. Same with creating the input element using document.createElement('input'); in the child window, passing it as a parameter to the window.opener window A, and there do the append. Only if I created the input element in the same window where I was going to append it, it would succeed without errors.
Thus my conclusion (please verify): no element can be dynamically created (using document.createElement) in one window, and then appended (using .appendChild) to an element in another window (without taking maybe a particular extra step I missed to ensure it is not considered XML or something). This fails in IE9 and throws the error, in FF this works fine though.
PS. I don't use jQuery.

Another reason this can come up is that you are appending before the element is ready e.g.
<body>
<script>
document.body.appendChild(foo);
</script>
</body>
</html>
In this case, you'll need to move the script after the . Not entirely sure if that's kosher, but moving the script after the body doesn't seem to help :/
Instead of moving the script, you can also do the appending in an event handler.

I got that error because I forgot to clone my element.
// creates an error
clone = $("#thing");
clone.appendTo("#somediv");
// does not
clone = $("#thing").clone();
clone.appendTo("#somediv");

Just for reference.
IE will block appending any element created in a different window context from the window context that the element is being appending to.
e.g
var childWindow = window.open('somepage.html');
//will throw the exception in IE
childWindow.document.body.appendChild(document.createElement('div'));
//will not throw exception in IE
childWindow.document.body.appendChild(childWindow.document.createElement('div'));
I haven't figured out how to create a dom element with jQuery using a different window context yet.

I get this error in IE9 if I had disabled script debugging (Internet Explorer) option. If I enable script debugging I don't see the error and the page works fine. This seems odd what is the DOM exception got to do with debugging either enabled or disabled.

jqModal/JQuery problem, div not updating with new content?

I'm hoping someone can point a relative jQuery/jqModal newbie in the right direction for debugging this error. I'm loading an html fragment into a div and then use jqModal to display that div as a modal dialog. The problem is that the div is displayed but not with my updated html.
I'm showing my jqModal dialog in the response from a jquery call, function foo is called from an onclick event:
function foo(url)
{
$.ajax({
type: "GET",
url: url,
success: function(msg)
{
$('#ajaxmodal').html(msg);
$('#ajaxmodal').jqmShow();
}
});
}
ajaxmodal is a simple div.
Initially I thought the problem must be in the html snippet (msg) I'm passing to the callback, but I don't think that's it, I get the err (see below) even when I comment out the $('#ajaxmodal').html(msg) line or pass it hardcode html. I think I have jqModal configured correctly, other calls using our ajaxmodal div work correctly, I'm able to display the modal, update the content based the server response, etc.
When I try to debug in firebug, I get the following error following the call to .jqmShow(). I have seen the err on occasion in other places when it seemed maybe the page hadn't loaded yet, and I confess I'm confused about that, since we've wrapped our jqModal selectors in a $(document).ready() call, so maybe I have a larger issue that this call just happens to trigger?
From the jquery.jqModal.js file, line 64: js err is $(':input:visible',h.w)[0] is undefined in the line:
f=function(h){try{$(':input:visible',h.w)[0].focus();}catch(_){}}
When I step through this in firefox, h.w[0] seems ok, it references our '#ajaxmodal' div.
Thanks in advance for any suggestions in tracking this down?

If you have no inputs that need focus, you can change in the jqModal.js from:
f=function(h){try{$(':input:visible',h.w)[0].focus();}catch(_){}},
to:
f=function(h){try{}catch(_){}},
That's what I did anyway ;)

I'm not familiar with jqModal, but you might want to try
append()
Rather than
html()
I'm not sure if that will help, but it's worth a shot

This question is a little on the old side, but this was one of the only results I could find on google for a similar situation so I thought I'd share my experience.
The line in question in jqModal is attempting to focus the first input element it finds within your pop-up form, and if there is none, an exception is thrown. This is why it is in the exception block - nothing bad happens if you disable firebug.
However, if you are like me and find errors bubbling up to be a bit on the annoying side, a workaround is to add a dummy input element to the element you are executing jqmShow on.

Found a soln to my problem, posting the result in case it helps someone else, though I don't quite understand it.
The issue (I think) has something to do with ajaxmodal not quite being initializel as a jqModal element when I make .html() call. Calling .jqmShow initializes the div with our default text. I had thought putting this in document ready function was sufficient to initialize the dialog:
$('#ajaxmodal').jqm({ajax: '#href', trigger: 'a[rel*=modal]', ajaxText: 'Loading...'});
but to solve my problem I had to reverse the calls:
$('#ajaxmodal').jqmShow();
$('#ajaxmodal').html(msg);
