In front-end development, SVG is a very common image format. jQuery is a very popular JavaScript library that can be used to process HTML and CSS, as well as SVG. This article will introduce how to use jQuery to change the styles and properties of SVG, as well as how to create and insert SVG.

1. Use jQuery to change the style of SVG

Changing the style of SVG can make the image more vivid. You can also use CSS to change the style of SVG, but it is also very convenient to use jQuery to handle the style. There are several ways to change the style of SVG using jQuery.

1. Use the attr() method

The attr() method can change the attributes of SVG, including style attributes. For example, to change the color of SVG, you can use the following code:

$("svg path").attr("fill", "red");

2. Use the css() method

In fact, you can use the css() method to set the style of SVG. Similar to setting the style of HTML elements, you can use the following code to set the style of SVG:

$("svg path").css("fill", "red");

3. Use the addClass() method

By adding a class name to SVG, you can change multiple style. For example, to add a class named active to SVG, you can use the following code:

$("svg path").addClass("active");

2. Use jQuery to change the attributes of SVG

In addition to changing the style of SVG, you can also use jQuery to change SVG properties. Here are several ways to change SVG properties using jQuery.

1. Use the attr() method

The attr() method can be used to change the attributes of SVG, such as changing the width and height of SVG. You can use the following code:

$("svg").attr("width", "100px").attr("height", "100px");

2. Use the prop() method

Use the prop() method to change the attributes of SVG, such as changing the viewport range of SVG. You can use the following code:

$("svg").prop("viewBox", "0 0 200 200");

3. Create SVG elements and Inserting SVG

Sometimes you need to use jQuery to dynamically create SVG elements and insert them into the page. Here are two ways to create SVG elements and insert SVG.

1. Create SVG elements

You can use the following code to create SVG elements:

var svg = '<svg xmlns="http://www.w3.org/2000/svg"></svg>';
var $svg = $(svg);

This code creates an empty SVG element and stores it in $ svg variable.

2. Insert SVG

You can use the following code to insert SVG elements into the page:

$("body").append($svg);

This will insert the SVG element stored in the $svg variable into the page .
