How to use jquery to dw

In today's website development, jQuery has become a very popular JavaScript library. Its use can simplify development work and improve the efficiency of the website. Dreamweaver is one of the most popular and widely used tools for building websites manually. If we combine the two, we can take advantage of DW to more easily build the jQuery functionality needed for our website. In this article, we will take an in-depth look at how to use jQuery correctly in DW to facilitate various website functions and effects.

First, to use jQuery in DW, we need to add the jQuery library to our website. This can be achieved in one of two ways:

1. Manually download jQuery in DW and add it to the website folder. In this case, we need to first go to jquery.com and download the latest version of the jQuery library files. Once the download is complete, we need to unzip it and add the folder to the DW project folder. Thereafter, we can include the jQuery library file in the HTLM document to use it for our JS code.
2. Use CDN link. CDN (Content Delivery Network) is a distributed network built based on the Internet cloud model. Its purpose is to distribute the content of static files to nodes around the world to improve access speed and file reliability. Therefore, we can use a CDN link (for example, jQuery official CDN) to add the jQuery library to our DW project.

Once we add the jQuery library to the DW project, we can include the jQuery library in our HTML document and start writing various jQuery functions and effects.

Here we will first introduce some basic jQuery functions so that you can better understand how to use them in DW.

Document ready function

$(document).ready() is a jQuery function used to execute code after the document is ready. It is a very useful function because it ensures that the code does not run before the DOM is loaded. This means that even before the document loads, focusing on the content of the page rather than the appearance of the page will keep it tidy. Creating this function code in DW is very simple:

$(document).ready(function(){
// 这里是您的代码 
})

Then when the page document is loaded, this function will be triggered and your code will be executed.

Selector Functions

jQuery selectors allow you to find specified elements in a document and apply actions. Different selectors can be used to process different elements. Here are a few selectors commonly used in DW:

1. ID selector: $('#id_name')
2. Class selector: $('.class_name')
3. Tag selector: $('table')
4. Attribute selector: $('input[placeholder="name"]')

The following A simple example of the code demonstrates how to use selectors to hide elements in DW:

$(document).ready(function(){
  // 选择元素
  var element = $('h1');
  // 隐藏元素
  element.hide();
});

Event handling function

jQuery event handling function is used to handle the response to user operations on the website. The following are some event handling functions commonly used in DW:

1. Click event: click()
2. Hover event: mouseover()
3. Leave event ：mouseleave()

The following is a simple example to demonstrate how to use event processing functions in DW:

$(document).ready(function(){
  // 选择元素
  var element = $('button');
  // 处理单击事件
  element.click(function(){
    alert('Hello World!');
  });
});

This is a simple click event function, which is used in user single A popup box will be displayed when clicking the button element in HTML.

Special Effect Function

Finally, we introduce some jQuery special effect functions used in DW. Here are some functions mainly used to create visual and dynamic effects:

1. Fade: fadeIn(), fadeOut()
2. Appear/slide: slideDown(), slideUp()
3. Animation: animate()

This is a short code snippet that demonstrates how to use the fade function in DW:

$(document).ready(function(){
  // 选择元素
  var element = $('h2');
  // 淡入
  element.fadeIn();
});

In this example, we Select the title element in the web page and use the fadeIn() function to fade it in so that it appears gradually.
