I am trying to work on a keydown event in javascript and I am currently stuck on something that never happened to me before :
var maxL = $("#myField").attr("maxLength")
console.log("Maximum Length : " + maxL);
if (e.key.length === 1 && str.length >= parseInt(maxL)) {
console.log(">>>> in if");
console.log(">>>> e.char == \"" + e.key + "\"");
e.preventDefault();
}
When I load the page, it fails. On debug, my server console logs this error :
Error Parsing /folder/myPage.xhtml: Error Traced[line: 384] The entity name
must immediately follow the '&' in the entity reference.
where 384 is the line where the if is
I tried both conditions individually and they work just fine, which leads me to think there is something wrong with the "&&" operator.
If this is of any importance, I work on a WebSphere server in JSF with PrimeFaces and I try to run it in Chrome. The javascript is embedded inside a div in order to delete it after the page is loaded :
<div id="deleteScript">
<SCRIPT>
//my script code
$("#deleteScript").remove();
</SCRIPT>
</div>
I actually had to use the following syntax :
<div id="deleteScript">
<SCRIPT>
<!--//--><![CDATA[//><!--
//my script code
$("#deleteScript").remove();
//--><!]]>
</SCRIPT>
</div>
Which I could find on this other answer. BalusC seems to think that we should only use this solution if we work for older web browsers, but it appears that it becomes necessary when we work on older JSF servers as well.
Looks like the jsf is interpreting parts of your js as if it was xhtml.
Wrap your script (after the <script> tag) with <![CDATA[ and ]]> to make it interpret the content literally:
<script>
<![CDATA[
//your code
]]>
</script>
The <![CDATA[ ... ]]> tags are used in XML files to allow the use of characters that usually are reserved such as '&', '>' etc. You can read more on this answer and here.
This is not a problem with the browser; It looks like your server is attempting to operate on the "&&". Maybe you have to escape it in your code.
The problem comes from the fact that you have your JS written in the html script tag. What I would do if I were you is:
<div id="deleteScript">
<script src="path/to/script.js"></script>
</div>
Since the script tag is within the div with ID "deleteScript", the element will exist when the script loads and you can delete it.

I have a web page which does navigation using templates and filling / showing them depending of user interactions.
It works quite well, but the templates contains some JS included with them. This JS code is correctly loaded (in the example below, it provides an alert saying "Hi") when the page is just loaded. However, I don't see the code within the debugger console, either in Chrome or Firefox.
I've provided a minimal example below, where I see in the console > Source, under localhost, only my HTML page and jquery.min.js in the asset/js sub-folder.
Here is my HTML :
<script src="assets/js/jquery.min.js"></script>
<template id="my_screen">
Hello
<script type="application/javascript" src="assets/js/testouille.js"></script>
</template>
<section class="container">
<div class="my_screen hide"></div>
</section>
<script type="application/javascript">
function useTemplate(elem) {
var myTemplate = $('#' + elem),
normalContent = $('.' + elem),
clonedTemplate = myTemplate.html();
normalContent.empty();
normalContent.append(clonedTemplate);
}
$(document).ready(function() {
useTemplate('my_screen');
}
)
</script>
And here is my Javascript :
alert("Hi");
Any idea?
Since testouille.js is in a <template>, it's not loaded automatically by the browser when the page is loaded.
When you clone the template and append it to a regular DIV, jQuery emulates loading the file using $.getScript(). In the Chrome debugger, code that's loaded this way will be shown in a VM:#### filename (where #### is an arbitrary number) in Sources, rather than with its actual filename.
You can make the debugger give this a filename by putting the following comment in testouille.js:
//# sourceURL=testouille.js
I am using PhpStorm 10.0.3. I have test.php file. Inside this file I have some JavaScript. What I found is, if there are any JavaScript syntax errors it does not show.
For example:
image.setAttribute("data-src2", "example.com/1.jpg";
no syntax error is shown at the end in the test.php
The entire file is
<html>
<head></head>
<body>
<?php
$you = "sample";
?>
<script type="text/javascript">
//image or frame
var image = document.createElement("img");
image.setAttribute("data-src", "example.com");
image.setAttribute("data-src2", "example.com";
contentDiv.appendChild(image);
</script>
</body>
</html>
If I rename the file to text.html then JavaScript syntax error is shown:
image.setAttribute("data-src2", "example.com/1.jpg";
it shows error saying , or ) expected.
How to ensure both the syntax errors are highlighted?
This mostly depends on your context. In other words, how is your JavaScript embedded on the page. If you use close tags ?> and then carry on with some JavaScript it should be able to recognise that this part isn't PHP any more.
You cannot do much about this unfortunately.
ATM injection fragments (different language inside another language) seems to be treated completely differently hence most of the inspections for injected language are disabled or not run at all (I guess it is because each such fragment is treated as separate document which often produced quite a few false positives .. and what is done here is one form of reducing such false alarms -- just my guess).

1 if (document.getElementById) {
2 document.write(
3 '<style type="text/css" media="screen">
4 #element1, .element2 {display:none;}
5 </style>'
6 );
7 }
I get "Uncaught SyntaxError: Unexpected token ILLEGAL" on line 3. This is probably soo easy for you guys, but I just started with JS and like always - it's a whole new language.
I could use 2 kinds of advice if they are different..
How to use this code in file.php between < script > tags?
How to use this code from seperate file.js file?
I know how to link .js, don't worry about that.
For the record, this is intended to be in < head > and to hide some html elements before they are fully loaded if Im not mistaken. Experts, feel free to confirm this or give me a better solution if there is any, thank you!
In JavaScript, strings cannot be broken up into multiple lines. The new line character is not a valid string character. You will have to close the string on each line and add the string concatenation operator after each line that is continued on the next line (or before each line that is a continuation of the previous line, like so:
if (document.getElementById)
{
document.write(
'<style type="text/css" media="screen">' +
'#element1, .element2 {display:none;}'
+ '</style>');
}
This will get rid of the error, but it will not achieve the desired effect of hiding elements. document.write automatically calls document.open() if an HTML document has already been opened (which it has, if the script is executing.) document.open will wipe out the contents of the page, including the script that contains that code. You will be left with a blank page.
As #Chris says, you can include script tags in the output of a php script simply by writing the script outside of the php parsing context. i.e.
?>
<head>
<!-- other stuff -->
<script type="text/javascript">// type="text/javascript" is only needed for browser versions that do not support HTML5
// place code here
</script>
<!-- other stuff -->
</head>
<?php
On the other hand, if you wish to include a separate, external JavaScript file, replace that script tag in the code snippet above with
<script src="[absolute or relative path to script]" type="text/javascript">
</script>
Note that script tags are not self-closing, so even though this script tag has no contents, you cannot use the self closing tag syntax, as in <script ... />

I'm not an expert on php, but this site says this is your basic syntax for embedded php.
http://php.net/manual/en/language.basic-syntax.phpmode.php
<p>This is going to be ignored by PHP and displayed by the browser.</p>
<?php echo 'While this is going to be parsed.'; ?>
<p>This will also be ignored by PHP and displayed by the browser.</p>
Also, it looks like you probably need to escape a few things for that tag.
'<style type=\"text/css\" media=\"screen\">
#element1, .element2 {display:none;}
</style>'
I just added CKEditor to my website, but I'm getting the following error in my console:
I followed the installation guide as it's written so I have no idea what's wrong.
Here's, briefly, what my call looks like:
<textarea id="full-editor" name="full-editor" rows="10" columns="6"></textarea>
<script type="text/javascript">
CKEDITOR.replace('#full-editor');
</script>
Aah.. try this
Remove # from the selector inside CKEDITOR.replace('#full-editor');
According to installation guide you shared, this is what u need
CKEDITOR.replace('full-editor'); // NO #. You must have got confused with jQuery
This also happened whenever we put initializer script before <textarea>.
Ensure to put
<script>
CKEDITOR.replace( 'editor1' );
</script>
before the </body> tag (i.e. closing body tag).
<script type="text/javascript">
CKEDITOR.replace('#full-editor');
</script>
Please add above code in external js file and include this js in html page after title page like
$(document).ready(function () {// save as like ckEditorInclude.js
CKEDITOR.replace('#full-editor');
}
<script src="Your folder path/ckEditorInclude.js" type="text/javascript"></script>
This also happened whenever we put initializer script before .
Ensure to put
CKEDITOR.replace( 'editor1' );
before the </body> tag (i.e. closing body tag).
This append to me because i was trying to use CKEDITOR.replace("editor") but there was no element in dom with Id or name "editor"
The issue for me was I copied the code locally from the cdn so that I can work on it if I am not online. I am using version 4.9.2 standard.
Examining the chrome console gave several 404 errors which were not obvious using FireFox. Reverting back to the cdn resolved the issue.
Unfortunately, no working offline with this it seems at least not for this version of ckeditor.
What parts of JavaScript code do I have to escape inside a script element in a HTML page? Is <>& enough or too much?
[EDIT] This is related to this bug: http://code.google.com/p/rendersnake/issues/detail?id=15#c6 comment #6
In HTML (and XHTML if you're an evil person that sends your XHTML pages as text/html), script tags are #CDATA, and therefore, the only thing that you shouldn't have in the content is </script>, as that is all that the parser looks for to signal the end of the tag. Don't escape anything; just make sure you don't have </script> in the tag content. For example, if you have a string with a closing script tag, split it up:
var a = '</scr' + 'ipt>';
In XHTML, sent as application/xhtml+xml, script tags are #PCDATA, and therefore, escaping < and & is necessary, unless you can use a <![CDATA[ ... ]]> block to change to #CDATA parsing mode, but in that case, remember that you can't have ]]> in your tag content.
Generally, the only thing I escape is the / in closing tags. Thus:
var msg = "<p>Do you <em>really<\/em> think so, Miss Worthington?<\/p>";
For the rest, I rely on commenting out the entire thing:
<script>
<!--
var msg = "<p>Do you <em>really<\/em> think so, Miss Worthington?<\/p>";
-->
</script>
The comment takes care of the HTML opening tags.
Escaped <, > and & does not work with many browsers. It is good an enough if you put everything inside a CDATA section. Please note that the CDATA section itself will have to be in a JavaScript comment, for this to work with all browsers.
<script>
// <![CDATA[
script here
// ]]>
</script>
