Html script scr won't work

there
I want to add my javascript file onto an html, but when I put
<script scr="check.js"></script>
The page won't recognise it. But if I add the jQuery file
<script scr="jquery-3.1.1.min"></script>
it recognises it.
Any ideas of why this happens and how to solve it?

<script src="check.js"></script>

You've got a typo...Just change "scr" to "src".

JavaScript in laravel-dompdf

I am using laravel-dompdf to generate a PDF with a summary of results, consisting of tables and a few images, nothing to spectacular. I would like to print highcharts in the generated PDF as well. So first, I want to try a simple javascript code to see if it was working... but it isn't. I have enabled the "DOMPDF_ENABLE_JAVASCRIPT" => true, but so far no luck yet. The simple code which I want to print:
<div>foo</div>
<span id="insertHere"></span>
<div>bar</div>
<script>
var el = document.getElementById('insertHere');
el.innerHTML = '<div>Print this after the script tag</div>';
</script>
This only prints the foo and bar.. Could someone please help me out?

Dompdf (or more specifically Back-end that it uses for PDF rendering) doesn't really render javascript. What it does is - it parse everything inside <script type="text/javascript"></script> tag and adds it in the special section of the pdf file.
I'm not sure if this javascript is what you need, since you can work with the dom tree outside of the <script> tag. What you can do is write simple scenarios, for example like this one:
<div>foo</div>
<span id="insertHere"></span>
<div>bar</div>
<script type="text/javascript">
app.alert({cMsg:"Message", cTitle: "Title"});
</script>
Try to open generated file and you will see alert.

How can I pass an html img element to a javascript included file?

This is a question from a noob in javascript. I tried to find something similar the last two days but I didn't find. I try to pass an html image element to an external javascript file which I include to the rest html code. The javascript fade in and fade out an image. Because I want to use different images everytime, thus I want to have a function in an external javascript file.
What I did so far:
PHP and HTML:
<?php
if ($success){
echo"<link rel='stylesheet' href='js/jquery-ui-1.11.4-smoothness.css'>
<script src='js/jquery-1.11.3.js'></script>
<script src='js/jquery-ui-1.11.4.js'></script>
<img id='tick' src='tick.png'>
<script type='text/javascript' src='js/success_failure_signs.js'>
success_failure(tick);
</script>";
}?>
Javascript file has this code:
function success_failure(tick){
var x = tick;
x.fadeIn();
x.fadeOut(1000);
}
The browser's console doesn't give any error.
It seems that the function success_failure doesn't get the image.
What is wrong on this code and how can I fix it?
Thank you in advance!

You haven't defined tick when you make your function call. Try this...
<script type="text/javascript" src="js/success_failure_signs.js">
</script>
<script type="text/javascript">
var tick = $("#tick");
success_failure(tick);
</script>
EDIT: I've also separated the inclusion of the script and your code to call it into two separate script tags.

maybe passing the image to the script is the wrong way of thinking here.
Most of the time with Javascript for web pages the JS gets the image from the HTML site itself.
You are already including jQuery so look into how to get an element from the page with jQuery.

trying to get the jquery Datepicker to function

I can't seem to get this working altho it is all on the website. I am not any good at js so that doesn't help either to be honest.
so I have basically done exactly the same as what they have on their website but just doesn't seem to function.
Signup open:<br><input type="text" name="reg_start" class="datepicker" value=""/><br>
Signup closed:<br><input type="text" name="reg_end" class="datepicker" value=""/><br>
This is there code what is the same as mine
<script language="javascript" src="protoplasm.js"></script>
<script language="javascript">
// transform() calls can be chained together
Protoplasm.use('datepicker')
.transform('input.datepicker')
.transform('input.datepicker_es', { 'locale': 'es_AR' });
</script>
Here are the includes I am doing
<link rel="stylesheet" href="jquery/datepicker/datepicker.css">
<script src="jquery/protoplasm.js"></script>
<script src="jquery/datepicker/datepicker_src.js"></script>
<script src="jquery/datepicker/datepicker.js"></script>
Here is the website I got the datepicker from
http://jongsma.org/software/protoplasm/control/datepicker
I understand that in their code they do not have the extra src includes but I put these in when I have been trying to get it working. I left them in the code as I think I will need to include them but not 100% as once again js isn't my strongest point because I am new to coding and need to get a lot more learning in js.
If anyone could help me out on how to get this working that would be great and I would appreciate any sort of help that you may be able to provide.
Thanks for reading

I managed to solve this problem I was having. What I done was I ended up putting the datepickers into .php file and then included it into my form. I added the js and css includes into this file as well and everything seems to work.
below I have included the link to the timepick I used and also my form, php include and the php what is needed to sort the date before sending to the database. If anyone finds this answer useful then please hit the +1 button.
Below is the link to jquery where I got the date and time picker from. The version I downloaded was 2.1.8 and you should be able to see the download button in right corner and it is a orange button.
http://plugins.jquery.com/datetimepicker/
Below is the .php file. I called it regend.php all of the jquery and css is included in the link above.
<link rel="stylesheet" type="text/css" href="jquery/master/jquery.datetimepicker.css"/>
<input type="text" value="date/time" id="regend" name="reg_end"/>
<script src="jquery/master/jquery.js"></script>
<script src="jquery/master/jquery.datetimepicker.js"></script>
<script>
$('#regend').datetimepicker();
$('#regend').datetimepicker({value:'date/time',step:10});
</script>
Below is the include that I added to my form. I added this within <form>.......</form>. I added it to the location I wished it to be displayed.
Signup close:<?php include("indexmodules/regend.php");?><br><br>
Below is the php code that I used before i sent it to the database to be saved.
$reg_end = preg_replace('#[^0-9]#i', '', $_POST ['reg_end']);
$unix_time = strtotime($reg_end);
$date2 = date("Y-m-d H:i:s",$unix_time);
All of the above code should help out any new beginner who is trying to get a date picker working on their website. If I enhance this code I will also post the updated version or version below this.
Thank you to the guys who commented on my original post and I hope this helps people out in the future.

Meteor.js: <script> tag doesn't work inside <body>

A simple script tag inside the body tag doesn't seem to work. The alert doesn't get triggered in the code below:
<body>
<script type="text/javascript">
alert('Hello');
</script>
{{>main}}
</body>
Any idea why?
Edit:
Just tried it with a fresh meteor app, no alert tag still:
<head>
<title>test</title>
</head>
<body>
<script type="text/javascript">
alert('Hello');
</script>
{{> hello}}
</body>
<template name="hello">
<h1>Hello World!</h1>
{{greeting}}
<input type="button" value="Click" />
</template>
Weird thing is when I copy paste the source of the html, made a new html page, and the alert will work.
Edit3: I deployed this app here: http://alert-in-body-test.meteor.com/
Do you get an alert box?

This question is still relevant in the current version of Meteor (version 0.5.4) so I wanted to describe how to include script at the end of the body.
To execute javascript at the end of the body, register a Handlebars helper and put the relevant code there, like this:
In client.html:
<body>
{{renderPage}}
{{afterBody}}
</body>
...
In client.js:
if (typeof Handlebars !== 'undefined') {
Handlebars.registerHelper('afterBody', function(name, options) {
$('body').append('AFTER BODY');
});
}
(For a great description of why this is required, see Rahul's answer to a similar question here: https://stackoverflow.com/a/14002991/219238 )

Its working for me
in onrender call this jquery
$.getScript('yours url')

It should work.
I have just pasted this inside one of my projects and it worked.
Your {{>main}} is strange for me tough. Also make sure that <body> is inside <html> tag.

Meteor is constructing the entire DOM from Javascript by rendering your page as a template -- the 'source' for your page as seen by the browser is basically:
<script type="text/javascript" src="/5a8a37bef5095c69bcd3844caf3532e1ba6d49bf.js"></script>
I can't find a definitive page stating that embedding a script tag in a template like this won't cause it to be executed, but it definitely feels against the spirit of what the framework is trying to achieve.
If the point is to achieve a clean separation of your markup and logic then why put it in the template. A better solution would be to use the meteor.startup call

Instead of looking the rendered html at developer tools, try looking the real downloaded html.
You will find a (probably) empty tag, with tons of script tags inside the .
In other words, the body of your meteor application is not the body of the final html, it's just your main template.
Instead, this ton on scripts shipped by Meteor, will load your templates.
So, your code will not run, cause it's been placed there. It's like when you manipulate DOM (with jQuery, for exemple), placing a script tag in DOM, after it's loaded. This script tag will not run.
