JavaScript Beginner Tutorial (Lesson 3)_Basic Knowledge

The purpose of this lesson is to call the target name, in this case the window name yer_new_window.

Now that we have briefly reviewed the href target, it’s time to start learning to open windows in JavaScript.

Opening windows in HTML is extremely common, but there are also some drawbacks; users browse The browser determines what the window looks like; you have no control over the size or style of the window. Fortunately, JavaScript gives you this control.

Take a look at the reason:

window.open("URL","name","features");

This statement is based on the first one you used when calling A parameter URL to open a window. This is a URL, which can actually be written as "http://www.jsfan.org/basic" or something similar.

The third parameter, features, is the different characteristics of a window. This is an optional parameter. Let’s do some exercises on the first two parameters first.

Here is another HTML page that will enter javascript_1.

The first line of the statement:

Here's a window named javascript_1.

When you click the link, a window named javascript_1 Open the web page where javascript_window_1.html appears. Since the features parameter is optional, we will ignore it for now.

Note here that I use onClick to call the window. You don't have to put window.open() in onClick to call the window, it's easy to do. You'll see an example of windows.open() in a
