Three Most Common jQuery Events Part Two: Keypress()


Keypress

In jQuery, keypress() method is a quick and easy way to add a key press listener to element(s).

I updated the HTML a little bit by adding a simple text input. 


If I want to get a print message every time when I press the key in the input, I will write keypress() function:

$("input").keypress(function(){
console.log("You Pressed A Key!");})

So no matter what key I press, the console will print out the message right after I pressed the key.


If we want to listen for a key press only we hit the "Enter" key, we need to check the key code for enter key first. 



The key code for "Enter" is 13. Therefore, we can write an if function in the keypress():

$("input").keypress(function(event){
if(event.which === 13) {
alert("You Hit Enter");}})

Intermediate Express.js: How To Add Styles & Partials in EJS File?

So far, we only have simple HTML tags and ejs tags in each ejs file. Every template page has no style at all. And the basic HTML header and footer are also missing. Today, I learned how to add styles and partials in ejs file. Link Style Step One: Touch a Separate CSS file I create a new directory "Style" under the "EJSDemo" directory, then I add a new CSS file "app.css" inside "Style" folder. Step Two: Add app.use(express.static()) in the app.js I add app.use(express.static("style")) in the "app.js". This will tell Express.js to serve the content of "Style" directory. Step Three: Write styles in CSS file I simple give body an orange background color and set text color to be grey. Step Four: Link to CSS file in the EJS file I just add <link> tag to link the "app.css" file on the top of the h1 tag in each ejs template. As the result, when I run the app and...

Intermediate Express.Js: Write Conditions and Loops In The EJS (study note)

We continue to use the app.js which we have build to be the study example. In the last post, we only add a simple EJS tag <%= thingVar %> inside h1 tag. This will match the "thing" to any "thing" request from the user. If Statement Today, the course shows us to write a simple if statement in the EJS file. I learn to apply it to my own app. In the if statement, if users send"/wantto/workout" request, the page will show a new content "Good Idea!". We wrote the if statement in the "diet.ejs" file, and we add "<% %>" tags around the code. We have to wrap every line of JavaScript anytime JavaScript starts and ends. Moreover, you may see there are two types of ejs tags here: <%= %> The one with equal sign. According to the course, when we add equal sign, the value that is returned inside of the tag will be rendered to the HTML page. it will be added to the HTML. For example, if we write ...

Authentication Project: Secret Page App Part One (Set up & Create User Model)

So far we only write the RESTful routes to send request and redirect to the related page, but we haven't do anything about authentication. If we can sign up, login, and log out, it will make our app more meaningful. Therefore, the course shows us how to create a secret page app, which will allow us to sign up, login to a secret page, and logout. Since it requires so many pieces, I will divided this project into three parts: set up & create user model, sign up, and login/logout. In this post, I am going to show all the set up process. Set Up Step One: Install packages The first thing we are going to do to create a folder "Auth", and inside of "Auth", we need to create another folder "AuthDemo". Then we cd (change directory) to "AuthDemo". Now we can set up the actual application structure by installing a few packages: passport, passport-local, passport-local-mongoose, mongoose, express, ejs, body-parser, and express-session....
