jQuery (Ajax) Contact form with all elements

This is my default CONTACT form built with jQuery and CSS.
The form uses a jQuery call to a PHP script that inserts data into a Mysql DB and sends two emails of confirmation, all this under the hood… meanwhile, there is a CSS only animation that displays a message that the data is been sent to the server and shows a positive message if that data was sent without errors and an error message if there was an error.

How to Optimize Your Website And Obtain a Google Page Speed of 98-100?

First, please backup your files before you start modifying anything I write in this post.

Thank You!

First, why you should follow my advice? Well, almost anyone can tell you that a fast website is a good website and a good website is a mobile and desktop 100% compatible website but, as a developer, you need to test your site with Google’s Page Speed tool(https://developers.goo…).

Obtaining a good grade there can help your search engine traffic… So, what Google Page Speed score your project gets?

I’ve done a few projects with 98-99 out of 100, and a few with perfect 100.

I will list here a few “secrets” I used to boost my grade from 68/100 to 99/100.

1. Use only inline CSS

You need to use only inline css, period. Don’t link to any external frameworks(Bootstrap, etc.), don’t link to any Google Fonts file, to any particular style…

If you want to be productive, you ca use PHP to include_once(“”); your css files into the interpreted file.

If you want to use fontawesome or Google Fonts, you can put fontawesome file before you close your </body> tag.

You can also modify the Google Fonts .css file and include it inline into your source via PHP. Also, you can remove all the Vietnamese or Greek fonts from the Google Fonts file and use only the Latin style, works with english projects and most of the languages.

2. Insert the .js files at the end of the file

This is no secret that, inserting the .js files before you close </body> tag can get you a good Page Speed grade.

3. Use Server Side compression(gzip)

This is a pretty easy step, I provided instructions here on another post on how to do that.

4. Optimize images

Don’t exaggerate with images, use a low resolution image thumbnail, I use only < 10kb images. Specify the width and height of the image. You can use a free online tool to reduce the size of the images.

5. Minify css, js and html

This step gives anyone a lot of work if you are updating your site constantly… You can use free online tools to minify your css, html and js code.

6. Reduce the Server Response Time

Don’t load your server with requests, use, as much as you can only static content or make Ajax requests to content.

Bonus Point!

Transform your favicon in BASE64 text and include the code via PHP and get rid of a few connections that can slow down your website… I use this tool to convert my favicons: https://xaviesteve.co…

 

Hope this experience helps, try and play with this list and tell me your result.

Take a look at a sample page that I’ve recently made and got a great score: https://developers.google.com…

jQuery load() external file inside div

Sometimes I use the jQuery load() function to display dynamic content inside html elements. As the description says:

load() Description: Load data from the server and place the returned HTML into the matched element.

I provided a working example that loads a simple html file with html tags and another php files that contains variables.

Here is the jQuery code:

Here is the PHP code that deals with the two variables:

jQuery .on() method with multiple event handlers

If you need multiple event handlers attached to the same selector executing the same function, you could use:

Learn more about jQuery events here.

What does this function really do? We have two div elements on our page and two different classes .field and .spn. When we click or mouseover over the .field class, the .spn div is showing the “Hello world!” text added via jQuery .text() method.

Responsive Google Map (Javascript & Google API V3)

This tutorial uses HTML5 and JavaScript to implement a responsive Google Maps map, no iframes or css code needed.

The main idea of this tutorial is to make the pointer on the map responsive / keep the pointer fixed on the chosen location on the map as we change the size of the window/map layout

Implementation guide

  • Get a Key/Authentication – Google Maps JavaScript API here
  • Edit the header line https://maps.googleapis.com/maps/api/js?key=[KEY]&callback=initMap and replace [KEY] with your unique Google Maps Key
  • Use Google Maps or other aplication to find the GPS coordinates of the location/pointer on the map and paste them on line 22 and 32 here like this: new google.maps.LatLng(51.506767, -0.1244953)
