Spline Technologies Corporation announces a major update to SplineTech JavaScript Debugger PRO, an independent standalone Web development tool that enables Web developers to easily edit and debug JavaScript and VBScript inside HTML and AJAX pages, without the need for any add-ons, plugins or changes of their code to handle the debugging process. Client-side JavaScript, JScript and client-side VBScript debugging languages are fully supported for simple and complex HTML, DHTML and AJAX debugging scenarios.

 SplineTech JavaScript Debugger PRO offers following main features to address the most common Web development issues:

 - Advanced form debugging for JavaScript form validation - Programmers to cause order forms to validate in clients' browser windows before they are submitted.
 - JavaScript pop-up debugging
 - Debug DHTML menus and JavaScript menus
 - Debug JavaScript and VBScript events: Debug JavaScript Pop-ups, onclick, onmouseover, onfocus and any
 other event.
 - Debug DHTML behavior
 - Debug client-side JavaScript controls: Debug calendars and any other control
 - Multi-Functional VBScript and JavaScript script editor for HTML and AJAX
 - Full Support for native VBScript and JavaScript syntax (color-coded)

OpenStreetMap is a free and open-source platform that is used to embed maps on the website. You can use OpenStreetMap API to embed maps with marker in HTML. Similar to Google Maps, OpenStreetMap is used to display maps with marker and info window. Mostly, the single marker is pointed on the map to display the location with marker and info window popup. We can embed maps with multiple markers and info-windows using OpenStreetMap API. Map with multiple markers are very useful when you want to show multiple locations on a single map. The user can see multiple locations with markers

Mostly the server-side scripting language such as PHP is used to upload file to the server. With this method, an HTML form is submitted to upload the selected file to the server. To provide a better user interface, we can use client-side technology such as jQuery Ajax to upload files without page refresh. Moreover, you can use simple JavaScript to upload files to the server. The JavaScript FormData interface provides an easy way to construct key/value pairs with form fields and send them to the server side using the XMLHttpRequest method. This technique can be used to upload files to

The web form is a commonly used element in each website. In some cases, the user is allowed to select files with the input data so that the files are attached to the form data. Mostly the default HTML file input interface is used to select and upload files. But if you want to make web form UI more effective, drag and drop file upload feature can be used. The drag-and-drop feature provides an advanced file upload interface on the web page. The user can drag the files from the local drive and drop them into the DOM element. In

When promises were introduced in ECMAScript 2015, they had an interesting flaw: if a promise didn’t have a rejection handler and was later rejected, you would have no idea. The rejection silently occurred behind the scenes and, therefore, could easily be missed. The best practice of always attaching rejection handlers to promises emerged due to...

If you write server-side JavaScript, chances are you’ve need to read information from environment variables. It’s considered a best practice to share sensitive information, such as access tokens, inside of environment variables to keep them secure. However, the way environment variables are read from JavaScript is error-prone in subtle ways that might take you hours...

Traditionally, developers have created properties inside of JavaScript classes for any data that might be needed within an instance. This isn’t a problem for small pieces of data that are readily available inside of the constructor. However, if some data needs to be calculated before becoming available in the instance, you may not want to...

User input from HTML form fields is generally provided to JavaScript as a string. We’ve lived with that fact for decades but sometimes developers need to extract numbers from that string.

When I visit a page, I get annoyed when I try to interact with elements while the website is still loading. Often stuff is moving around, fonts aren’t quite loaded, and it feels broken.

I know nowadays we’re obsessed in this industry with gaining every millisecond in page performance. But in a couple of projects that I recently overhauled, I added a subtle and clean loading mechanism that I think makes the experience nicer, even if it does ultimately slightly delay the time that the user is able to start interacting with my page.

In 2022 I think it’s still important as a web developer to test your how your websites look and function when users disable JavaScript in their browser. Developing in this way used to be a cornerstone of Progressive Enhancement and can be handy on both desktop or mobile.

I still find myself wanting disabling JavaScript on pages I visit. Sometimes it’s to test a page I’m working on, but in other instances it’s simply to visit a web page that’s not functioning correctly and I want to see if JavaScript is the culprit.

By now, everyone knows how to detect and use localStorage. However, I’ve been using a seemingly unconventional (but slightly more efficient) technique to do so. Since I haven’t seen it documented anywhere else, here goes!

As a follow-up to the post documenting a few popular HTML element + attribute notations, here’s a similar one about JavaScript.

Having recently written about character references in HTML, I figured it would be interesting to look into JavaScript character escapes as well.

Does JavaScript use UCS-2 or UTF-16 encoding? Since I couldn’t find a definitive answer to this question anywhere, I decided to look into it. The answer depends on what you’re referring to: the JavaScript engine, or JavaScript at the language level.

Did you know var π = Math.PI; is syntactically valid JavaScript? I thought this was pretty cool, so I decided to look into which Unicode glyphs are allowed in JavaScript variable names, or identifiers as the ECMAScript specification calls them.

Fun fact: var foo = { H̹̙̦̮͉̩̗̗ͧ̇̏̊̾Eͨ͆͒̆ͮ̃͏̷̮̣̫̤̣Cͯ̂͐͏̨̛͔̦̟͈̻O̜͎͍͙͚̬̝̣̽ͮ͐͗̀ͤ̍̀͢M̴̡̲̭͍͇̼̟̯̦̉̒͠Ḛ̛̙̞̪̗ͥͤͩ̾͑̔͐ͅṮ̴̷̷̗̼͍̿̿̓̽͐H̙̙̔̄͜: 42 }; is valid JavaScript. It may not be immediately obvious, but the real surprise here is that the Cthulhu-esque property name is not surrounded by quotes. Intrigued by this, and having written about the similar topic of JavaScript identifiers before, I decided to look into valid property names in JavaScript. When do they need to be quoted? When can the quotes be omitted? And in which cases can dot notation be used instead of bracket notation to get or set a property based on its name?

Looking for a list of all reserved words in JavaScript? You’ve come to the right place. I recently needed such a list myself, but ended up comparing the reserved keywords in all ECMAScript versions as well. The result is listed below, for future reference.

The way JavaScript handles Unicode is… surprising, to say the least. This write-up explains the pain points associated with Unicode in JavaScript, provides solutions for common problems, and explains how the ECMAScript 6 standard improves the situation.

ES2015 updates the grammar for identifiers. This affects a number of things, but most importantly, identifiers can be used as variable names, and identifier names are valid unquoted property names. This post describes the observable changes compared to the old ES5 behavior.
