How to set button text in jquery button

In the process of web development, button is a commonly used UI component. Typically, buttons play an important role in how users interact with a website. For example, buttons can be used to submit a form, execute a script, navigate to a new page, and more. jQuery Button is a very popular jQuery UI component that allows developers to quickly create and customize various types of buttons. In this article, we will learn how to set text using jQuery Button to create buttons with different styles, sizes and texts.

What is jQuery Button?

jQuery Button is a UI component provided by the jQuery UI library. It is built based on HTML and CSS and contains a variety of button types, such as check boxes, radio buttons, push buttons, and continuous buttons. jQuery Button has the following features:

• Customizable appearance and style
• Customizable button size, text and image
• Supports union and group buttons

How to set button text using jQuery Button?

jQuery Button provides a method to set the button text, namely button("option", "label", newText). We can use this method to change the text of the button. The following is an example that demonstrates how to use jQuery Button to set button text:

$( "#button-id" ).button({ label: "原始文本" }); //改变按钮文本 $( "#change-text-button" ).click(function() { $( "#button-id" ).button("option", "label", "新文本"); });

In the above code, "button-id" is the ID of a button, and the button whose text you want to set is selected by this ID. In the example above, the button's text is the "original text".

When using the .button() method to initialize a button, you can pass in the configuration object so that it has preset text content. In this initialization object, you need to use the "label" attribute to set the text content of the button. For example: $(element).button({label: "Button text"}).

When you need to change the text of a button, you can use button("option", "label", newText) to achieve this. Where the first parameter is the ID or JQuery object of the button whose property value you want to change, the second parameter is the name of the property you want to change, and the third parameter is the new text. This method can flexibly control the change of button text.

Style and size

jQuery Button not only provides basic style settings such as changing the button text color and font, but also changes the button style by changing the class. For example, you can set a warning category button by adding class "ui-button-warn".

In addition, sometimes you need to change the size of the button, and the method is equally simple. By default, buttons are available in three different sizes: large ("large"), medium ("medium"), and small ("small"). If you need to change the button size, you can add a size parameter directly to the .button() method, for example:

$(element).button({ size: "large" });

The above code will create a button with a larger size. Other possible values include medium and small.

Summary

Through the above introduction, we have learned how to use jQuery Button to set properties such as text, button style and size. Using jQuery Button can greatly simplify the UI design in the web development process and improve development efficiency. At the same time, we can also combine CSS, JavaScript and other technologies to further improve the display effect of buttons.
