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.

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 ...

My Story: A Mommy Start To Learn Code From Zero

From Google Image I am not a programmer, and I thought I would never become one. Everytime I see someone is coding, I think he or she must be very talent. For me, coding is a very difficult subject to learn. Not only the language has so many rules, but also the logical reasoning behind the language is complex. In my graduated school, I knew many friends who didn't have any coding background, but they are doing programmer or developer jobs now. Some of them went to school to study coding, and some of them learned to code by themselves. Their stories are so impressive. I wasn't ready to learn code until I finished my first Chinese book "留学，我的青春呀!" recently. I always want to be a writer and write my own book. I started writing blog three years ago, and I updated my post two to three times every week. As I enjoyed writing , I started to get some followers, likes, and good comments on my blog. Then, I decided to plan my first book. My First...
