Seven Most Common jQuery Methods Part Two: ATTR() and VAL()

.attr()

According to jQuery, it can get the value of an attribute for the first element in the set of matched elements or set one or more attributes for every matched element.

So I use the img tag to add an apple image at the bottom of the page.

Now I want to change the apple image to a banana image, so I select the img first, and change the "src" attribute value to a new image address.

$("img").attr("src", "the new image address")

If I want to change the input type from text to color, I can write: $("input").attr("type", "color"). As the result, the input box changes to a color input.

.val()

According to jQuery, this method gets the current value of the first element in the set of matched elements or set the value of every matched element.

I type my name in the input, and then I call my name in the console by typing $("input").val().

If I want to update the input name, I can write the new name inside the val().

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...

Intro to Backend: Is Browser The Only Place To Send HTTP Request?

Today, I begin to learn the second part of web develop course: backend. Frontend is the stuff that we can see and interactive with, such as HTML, CSS, and JS. We can type our code, style our page, or write some function to make interaction. However, backend is everything else. For example, we type Target web address in the Internet Browser. As we hit "enter", there are a few steps to go through: 1. The HTTP request is sent to a particular server's IP address. 2. The server figures out what to send us 3. It sends a HTTP response back to us Those process we are hard to see, and it happens in less than one second. The instructor said that the browser is not the only place to send the HTTP request, and there are so many choices out there. In this learning course, we are going to use Postman App . Postman allows us to make HTTP requests and viewer responses. It is really for developers to understand how things are working or debug something. In the P...

Seven RESTful Routes You Should Know!

I have been followed the course to develop several app projects. They all follow the RESTful route pattern. Today, I learned many key points about RESTful and would like to share my study note here. What Is REST? REST stands for representational state transfer. I don't know what does this mean, but it is not important right now. You just need to know that REST is just a pattern for defining our routes. What's The Point Of REST? The important things for us is to define what REST is. REST is a way of mapping HTTP routes and CRUD functionality together. By the way CRUD stands for Create, Read, Update, and Destroy. The point of REST is that we don't do whatever we want. Instead, we follow a pattern. It is also more reliable so that if we are interacting with a restful API, it follows a particular pattern. Seven RESTful Routes The course lists the seven route table. It just acts as a pattern that we can fill in the blanks when we develop our own App. screen...
