Javascript And HTML Entities

Nov 22, 2006

I need some help with Javascript and HTML entities. I am writing some code and I need to use quite a few HTML entities on alert boxes (messages in different languages)

Unfortunately Javascript displays the entities and not the equivalent caracther.

Javascript Entities

Jul 23, 2005

I would like to set the value of a hidden input field to the value of
a javascript variable.

In HTML I have successfully done this by:
<input type="hidden" name="context" value="&{exists};"/>

However I now wish to put this into an xsl file and it complains about
the { characters.

If I change them so that I have:
<input type="hidden" name="context" value="&lsaquo;exists&rsaquo;"/>

Then I get an error along the lines of the entity lsaquo was
referenced, but not declared.

Document.write, HTML Entities And IE

Jul 20, 2005

Using my IE v.6 browser, document.write doesn't convert HTML entities
(e.g. &apos;, &amp;) to the appropriate character (though NS 6.2 works

Obviously I can get round this for particular entities by writing some
code to do the conversion before using document.write - but I need a
more general solution that will catch any of the HTML entities.

A trawl with Google has found a number of people raising the question,
but no answers. Any suggestions?

JQuery :: Use Clear Link To Hide Html Entities?

Jun 18, 2010

I have a large set of input fields (of checkboxes and radio buttons), and aside each set, is a clear button (just looks like text you can click on) that clears any input next to each of the input fields. When no input buttons are selected, the HTML entities that depend on them are supposed to disappear, and this works on load.

My question is how does one easily incorporate that clear button so that it tells the listeners already in action to clear those entities when they click on clear, and without having to manually do it over again with the clear button, if that makes any sense.

I'm trying to write/find a regular expression for finding ampersands but not HTML entites.I have this which finds entities but can't figure out how to ignore entities and return unmatched "&"


Test string: ThisĀ is sample test containing a bunch of & and entities. Do you shop at: M&S? &x#1234;

I want to HTML encode the non-entity ampersands for insertion into XML e.g.
"bunch of & and" --> "bunch of & and"

Regular Expression :: Match Letter But Leave Html Entities Alone

Mar 14, 2007

I need to figure out a pattern that can match each letter of the message, but leaves all the html entities alone.

For example, I have a input like this:

This is the content &nbsp; &lt; Hello &gt;

Just as an example to make it more clearer, If I wanted to replace the all letters of the message with the number "1" I would have this result:

1111 11 111 1111111 &nbsp; &lt; 11111 &gt;

JQuery :: Web Service XML Return Is Turning Tags To HTML Entities?

Jun 11, 2010

I am using the ajax method in JQuery to return an XML response from a URL location. The method looks like the following:

url: '../DSMO/lb.asmx/GetAvailableDocListAuth',
cache: false,
type: 'POST',


OK so if I use repsonseText responseXML or just try and traverse msg it will not work. The problem is the body of my XML response, all of the tags ('<' and '>') are getting escaped to html entities ('<' and '>') So it becomes a malformed XML document that is not readable. I even tried using the Javascript function replace to go through and replace with no luck.

Even stranger if I access the web service through the browser, the XML is just fine!

The server is Windows Server 2008 running IIS 7 and I am programming of course in HTML and newest version of JQuery.

The browser I am testing on is Firefox with FireBug.

CreateTextNode And Entities

Feb 25, 2006

Modified with a newer version since it was first posted. Some comments may refer to older versions.

function entity(str, mode) {
str = (str) ? str : "";
mode = (mode) ? mode : "string";

var e = document.createElement("div");
e.innerHTML = str;

if (mode == "numeric") {
return "&#" + e.innerHTML.charCodeAt(0) + ";";
else if (mode == "utf16") {
var un = e.innerHTML.charCodeAt(0).toString(16);
while (un.length < 4) un = "0" + un;
return "u" + un;
else return e.innerHTML;

entity() has two parameters:

- entity: is a string which can be either a named entity (&raquo;), numeric entity (&#187;), UTF-16 value (u00bb), or even the character itself (»).

- mode: is an optional value that can be 'string', 'numeric', or 'utf16'. This tells the function what to return the value as. Defaults to 'string'.

You'd use it like this:

// String mode
var div = document.createElement('div');
var text = document.createTextNode('Parent '+entity('&raquo;')+' Child');

// Numeric mode
var description = "The entity for » is "+entity('»', 'numeric');

// UTF-16 mode
var description = "The UTF-16 value for » is "+entity('»', 'utf16');

Script Stop Working When Bringing In 2 New Entities?

Sep 22, 2011

This code was working fine until I added "["lastname"]["email"]" to it. Why has this problem developed? Was I suppose to separate them or something?

<SCRIPT type="text/javascript">
function validateForm() {
var x=document.forms["form"]["firstname"]["lastname"]["email"].value;

Dynamically Writing Html/javascript From A Javascript Function

Jul 23, 2005

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs

The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at but that doesn't do exactly what we need.

Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.

I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie


would become

document.writeln('</SCR' + 'IPT>');

I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.

Here are the 3 files (keep in mind wordwrap has jacked up the

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"

Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG

function newWindow1(pic,sitename)
{'','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');

function resizewindow()
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");

Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task

Javascript Parsing HTML From XML

Jul 20, 2006

I have an XML file that among other things has the following node.
As you can see it contains HTML tags.

<description lang="en">
<div class="descrBoxRight" style=" top:250; left:200">

With javascript, in Mozilla, I easily retrieve the content of the
XML "description" tag using the following line of code

var myStuff = myDescrNode.textContent;

However, in IE (6.0)

var myHTML = myDescrNode.textContent;


var myHTML = myDescrNode.innerText;

do not work, resulting in myHTML being undefined.

Alternative solutions? Should I remove the CDATA tag
and use a completely different method?

JavaScript In HTML: Unexpected Outputs

Jul 23, 2005

I'm learning/experimenting with some simple JS/html markup, running
an apache daemon and mozilla firefox browser in RH 9.

Let's say I run the following markup with one or more of lines 6-10
commented out:

1 <html>
2 <head>
3 <script type="text/javascript">
4 function showinfo()
5 {
6 width = window.screen.availWidth;
7 document.write("<br>screen width=
8 document.write(width);
9 document.write("<br>Date: ");
10 document.write(Date());
11 }
12 </script>
13 </head>
14 <body onload="showinfo()">
15 <p>

My question: is there a simple explanation to account for the 'unexpected'
behaviours below (Runs 1, 3, 5)?

Run 1: nothing in 6-10 commented out; output (expected more):

screen width=

Run 2: line 7 commented out; output (as expected):

Date: Wed Apr 14 2004 20:55:58 GMT-0400 (EDT)

Run 3: lines 7, 9, 10 commented out; output (as expected, but unfinished loading):

[ongoing hourglass indicating loading in progress]

Run 4: lines 7, 10 commented out; output (as expected):


Run 5: lines 7-9 commented out; output (as expected, but unfished loading):

Date: Wed Apr 14 2004 22:46:49 GMT-0400 (EDT)
