Seven Most Common jQuery Methods Part One: Text() and HTML()


The course introduced seven most common jQuery methods that can save us a lot of time and make our code super clean.

  • .text()
  • .html()
  • .attr()
  • .val()
  • .addClass()
  • .removeClass()
  • .toggleClass()
Today, I am going to share the first two methods study note with you.

I start to create a simple HTML page includes h1, an simple input and a fruit list.


Then, I link to the jQuery file and check if it is connected correctly.


.text()

According to jQuery, this method can get combined text contents of each element in the set of matched elements, including their descendants, or set the text contents of the matched elements.

For example, if I want to see the h1 text content in console, I just need to type $("h1").text(). Then, it will call back the h1 text.


We can do the same thing to the list content, too. When I select the li, it will return all list items in a string.


text() method can also change the content. I can change the h1 text content by adding the new content inside the text().

.html()

According to jQuery, it allows to get the HTML contents of the first element in the set of matched elements or set the HTML contents of every matched element.

If I want to see the HTML of the list, I can type $("ul").html(). It will return the HTML content.


If I want to update the HTML list, we can enter the new HTML list in the html(). I updated the list from three items to two items.

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...
