I am having some problems with Netbeans' Javascript/Jquery Intellisense. I am using Netbeans 7.1 on Windows. For instance :
I have PHP project with :
jquery.js in source files
index.php in source files
script.js in source files
Then I write something simple like this :
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="script.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("h1").click(function(){
$('<h1>Hello</h1>').prependTo('body') ;
});
});
var myDate = new Date();
var m = myDate.getMinutes();
</script>
</head>
<body>
<h1>hello</h1>
</body>
</html>
With this example I get some Intellisense in index.php file but it is somehow not complete (as for me) for $('h1').cl Intellisense does not list click but shows somehting like this
In the script.js I do not have any Intellisense for jQuery - only Javascript's.
I also don't get e.g. Date's Intellisense. I only get this :
How can I fix this ?
Could it be that you have your IDE set up to hide features that are not supported in your target browsers?
for instance, in my Netbeans, it shows them with a strikethrough and says they aren't supported in Internet Explorer 5.5
Try changing your targeted browsers:
Tools > Options > Miscellaneous > JavaScript

Just embarking in learning yet another language (JavaScript) and following instructions from a tutorial. I have node and Brackets (the editor) installed. The tutorial was requesting the following to be put in a file named
"app.js":
$('form').on('submit',function () {
var text = $('#message').val();
alert(text);
return false;
});
The problem I have is that the system immediately complains that "$" (two places) and "alert" are undefined.
The index.html file was originally requested to specify:
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>
<script src="app.js"></script>
at the bottom (which caused the system to complain with an earlier simplified version about 'alert') but I replaced it with the following after visiting the code.jquery.com site:
<script
src="http://code.jquery.com/jquery-3.3.1.js"
integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60="
crossorigin="anonymous"></script>
<script src="app.js"></script>
This solved the alert issue when the .js file was nothing more than a 'hello world', but now I have a "problem++" with the next version of the .js file shown above.
I suppose it could be something about the installation and/or paths; but I am at a loss figuring where that could be and how to fix it. Can any expert suggest something?
For the record: I am on a Windows 7 machine, using Chrome to display the html file.
Many thanks
Edit:

did you add the jquery link twice?
Please remove all jquery links and do the following:
remove all previous jquery links.
Add this code snippet between your head tags.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
When I'm editing the below example HTML page in Visual Studio Code (borrowed from Facebook's React tutorial and slightly edited), if I write any Javascript code in the script block, it is not syntax highlighted. But if I change the script block type to "text/javascript" then the syntax highlighting works. But then any React-y/JSX code doesn't work as it is wired to work through Babel.
Is there any way to have the script tag "type" attribute set to "text/babel" and at the same time have proper syntax highlighting in Visual Studio Code?

<script type="text/babel">

I found a solution to this now.
Open up: (VS code home dir)\resources\app\extensions\html\syntaxes\html.json, and edit the regex for the script tag. That fixed the issue for me.
Well this is a workaround, probably will be better to change this in a post build process, but I found an easy way to do it with this new feature TagHelpers which will help to replace the javascript value by babel
So add a file TagHelpers/ScriptTagHelper.cs
[HtmlTargetElement("script", Attributes = "to_babel")]
public class ScriptTagHelper : TagHelper
{
public override void Process(TagHelperContext context, TagHelperOutput output)
{
output.Attributes.SetAttribute("type", "text/babel");
}
}
In your page Index.cshtml
<script type="text/javascript" to_babel>
And dont forget to import TagHelpers in _ViewImports.cshtml or in your Index.cshtml
#using app1
#addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
#addTagHelper *, app1
And voila! this render as babel.
I've come with hopes that I can achieve a functional answer to my series of baffle. I have tried linking my indexjs.js to my index.html using <script type="text/javascript" src="./indexjs.js"></script> --- yet to no avail. I have also tried inline editing such:
link type="text/css" rel="stylesheet" href="./indexcss.css"/
script type="text/javascript"
$(document).ready(function(){
$('div').mouseenter(function(){
$(this).fadeTo('fast',0.5);
});
$('div').mouseleave(function(){
$(this).fadeTo('slow',1.0);
});
});
/script
also to no avail. With sidenotes intact I have tried several JQuery installations and the plugin but receive an error code upon is finalization similar to: Windows Script Host
Script: C:\Users\....\Desktop\public_html\indexjs.js
Line: 1
Char: 1
Error:'document' is undefined
Code:800A1391
Source: Microsoft JScript runtime error
I have used googleajax referenceing through src ; as well as saving jquery-1.12.4 to the same public_html folder.
Seems the issue is with link & script tag
Note < & >
HTML LINK TAG
<link rel="stylesheet" type="text/css" href="href="./indexcss.css">
Script Tag
<script type="text/javascript">
$(document).ready(function(){
//Rest of code
});

I had downloaded jQuery.js file from jQuery.com .I have saved this file in 3 places, including JRE/Lib and desktop (where my HTML file which calls it is), to be sure that the jQuery.js file is found. I reference this js file as :
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(function(){
$("#clas").click(function(){
$(this).hide();
});
});
</script>
</head>
<body>
<p id="clas"> Hello</p>
<p>Hi</p>
</body>
When I ran this HTML file on Mozilla browser, I expected 'Hello' to vanish when I clicked on it, but it did not. It remained as solid as ever.
But when I used a jQuery CDN:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js">
And when I used an online HTML editor called Tryit Editor v1.5, it worked correctly!
It seems only the local jQuery.js is not doing its part. The JavaScript works fine, only the $() part doesn't. I'm using jdk1.6. I wonder why this snag has occurred. How to resolve it? Help.
Thanks! I found the solution to this problem, from a similar question posted in this forum, asked a year ago. Here is the link:
jQuery code doesn't work if I'm using a local jquery.js file, why?
The problem seems to have been incompatible encoding of the html and the js files. So I added the charset attribute to script tag of js. And the problem and 'Hello' both vanished at a click!
Your code works for me. Please check the below code, I have just modified the location of the jquery.js file where mine is stored in a different location.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<%--<script type="text/javascript" src="jquery.js"></script>--%>
<script type="text/javascript" src="../Scripts/jQuery/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(function () {
$("#clas").click(function () {
$(this).hide();
});
});
</script>
</head>
<body>
<p id="clas">Hello</p>
<p>Hi</p>
</body>
</html>
I assume the location of your js is not correct. Are you using the same path of js where you have this "html" or jsp page? Or you have the js files in a separate folder?
Additionally, you can try alternate way as below:
$("#clas").live("click", function () {
$(this).hide();
});
Please let me know if this helps.
<html>
<head>
<script type="text/javascript">
document.write('f*** js');
document.write("f*** js!");
</script>
</head>
<body>
<script type="text/javascript">
document.write('f*** js');
document.write("f*** js!");
</script>
<div>f*** js</div>
</body>
</html>
I want use xpath to catch all lable object in the html page above...
In [1]: import lxml.html as H
In [2]: f = open("test.html","r")
In [3]: c = f.read()
In [4]: doc = H.document_fromstring(c)
In [5]: doc.xpath('//a')
Out[5]: [<Element a at a01d17c>]
In [6]: a = doc.xpath('//a')[0]
In [7]: a.getparent()
Out[7]: <Element div at a01d41c>
I only get one don't generate by js～
but firefox xpath checker can find all lable!?

Not a clue about javascript-aware parser in python but you can use ANTLR to do the job. The idea is not mine so I'm leaving you the link.
It's actually quite cool because you can optimize your parser to selectively choose what instruction needs to be parsed (and executed).
In Java there is Cobra. I don't know any Javascript-aware HTML parser for Python.
Searching google for "javascript standalone runtime", I found jslibs: a "standalone JavaScript development runtime environment for using JavaScript as a general-purpose scripting language", based on "SpiderMonkey library that is Gecko's JavaScript engine".
Sounds great! I haven't tested yet, but it seems like this will allow you to run the javascript code you find in the page. I don't know how much it will be tricky, though..
