How to make a Javascript library? - javascript

I want to know how can we write the below code snippet in a Javascript library:
<SCRIPT FOR="eventlib" EVENT="MyEvent(strTest)">
alert("Uploading files...please wait");
</SCRIPT>
and also below code snippet:
<SCRIPT LANGUAGE="JScript">
function ctrl::ClickEvent(a,b)
{
alert("MyWindowControl_ClickEvent");
}
</SCRIPT>
I am getting syntax error when I try to write the above snippets in a Javascript LIBRARY.

You can't include the script tags when inserting into a Lotus Notes javascript library. Only functions.

Instead of writing the Script block, we can write a Javascript function. From the event handler we can call it.

Unable to use jQuery in the javascript function that define in external js

::SOLVED::
I have an index.php and I define some JavaScript function for do some thing in this page. I use jQuery in this functions. When I put the functions in the index.php between tags all thing work good but I need to put this functions in external is file. When I do it and then import it in index.php, the js file load and the part that don't use jQuery, work good but the jQuery actions not work! I have put the jQuery before is in head of index.php. the jQuery load and I test it by simple alert. I tried to put $(function).ready() surrounding the js function and other time surrounding the function content but it doesn't work!
<script language='javascript' src="/js/jquery-3.4.1.js"></script>
<script type="text/javascript" language='javascript' src="/js/external.js"></script>
And external js file like this:
function doSomething(){
//some JavaScript code that work good
//some jQuery code that doesn't work!
}
Where is wrong?!
Excuse me for my stupid question!
First of all write better HTML code.
<script src="/js/jquery-3.4.1.js"></script>
<script src="/js/external.js"></script>
function doSomething(){
console.log("I'm executed");
if (typeof jQuery !== 'undefined') {
console.log(jQuery.fn.jquery);
} else {
console.log("jQuery library not loaded check your Network tab");
}
}
Then seems your jQuery not loaded check your network tab for loaded scripts.

Is there a way to use javascript code without using <script> tag?

So I'm working on my online portfolio using prosite.com and I created some simple hover thingy using javascript (http://wojtek.szukszto.com/index.html). The problem is prosite.com won't allow me to use < script > tag... Is there any way to do it? Maybe as an external html? I don't know... I'm not really good in coding, so any help would be appreciated.
You can have them as DOM Events like
<div onclick="alert('cat');">
I <strong>Really</strong> want a cat!
</div>
<body onload="//you can put a whole bunch of stuff here"></body>
(It is equivalent to window.onload = function(){ //stuff })
You can put your javascript code into external file and call in the head section of your html document
<head>
<script src ="/JS/yourjsfile.js"></script>
</head>
hope that your host allows you to call JS in the head section
The way I do it is by stating the type of script. The ProSite already has javascript integrated within itself. I use:
<script type="javascript"> Code-Goes-Here </script>

Script src inside jquery function

I want to do something like this:
$("#startButton").click(function() {
<?php if(somecondition){ ?>
<script src="some-external-js-srouce"></script>
<noscript><img src="irrelevant"></noscript>
<?php } ?>
});
Meaning that I want to execute some external javascript inside a jquery function if a button has been clicked. Can you help me?
You're putting HTML inside JavaScript. That's not quite possible.
You probably want $.getScript to load and execute a script dynamically at runtime. It does not support <noscript> but you're using JavaScript for it anyway, so that does not really make sense to me...
if you want to execute a javascript function from an external file then you can try like this -
<script type="text/javascript" src="myjs.js">
// code that will refer functions of myjs.js
</script>
use jQuery.getScript( url, function(){});

Struggling With Some Simple Javascript

I am trying to write my javascript functions in a separate file functions.js. Right now that file consists of one function:
function noOverlay() {
$('.overlay').css('display','none');
};
In my html I have these two lines:
<script type="text/javascript" src="/functions.js"></script>
<script>
$(document).ready(
noOverlay()
);
</script>
Essentially what I am trying to do is house a function in an external file and call it in my html. Maybe $document.ready isn't the right way to do this. Or maybe I am just making a silly mistake. Thanks!
Make sure you are importing jQuery and try:
<script type="text/javascript" src="/functions.js"></script>
<script>
$(function () {
noOverlay();
});
</script>
$(document).ready(function(){
noOverlay();
});
Check to make sure the js file was loaded with firebug or chrome's dev tools
Also make sure you load jQuery beforehand as well.

javascript error: this.node is null or not an object

I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio:
Microsoft JScript runtime error: 'this.node' is null or not an object
and it point to some function inside the JavaScript like
this.node.onload=function(){..............//I am not a java guy so do not know much about this
Where am I going wrong? Why does the site compile correctly but throw this runtime error?
I also tried inserting this java code inside the master file in the <head>, but same error. This is urgent please so if someone experienced can pinpoint where exactly to put the code that would be solve my problem quickly.
Have you included a reference to the jQuery library? A good practice would be to have the jQuery include in the Master.
<head>
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js">
</script>
<!-- the remainder of your .js references should follow-->
</head>
If it's your intention to have that script run on 'page load', then ensure you have it set correctly:
$(document).ready(function() {
// put all your jQuery goodness in here.
});
More info on jQuery document ready.
I'm not sure exactly what it is you are doing with that snippet of code, but I don't think it is the proper syntax.
You probably should re-write it to look like this:
$(document).ready(
function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
Just passing in the function to the jQuery selector will probably get some wonkiness.
Thank you everyone! there was no problem with either the syntax in the javascript or the location/page where it was first included by me. I just figured out that the mistake was somewhere else. This javascript works on an <img> tag. It zooms the image insdie the <img> tag. I was using the <asp:ImageButton> instead og <img>. It works perfect as soon as I replaced it. Thank you all for your time and the knowledge sharing.
