jquery remove input style

In web design, it is often necessary to obtain user input data through HTML forms. When users enter data, the style of the input box will directly affect the user's input experience. However, the text input box that comes with the browser may not meet the designer's requirements. Therefore, designers need to use some techniques to make the form more beautiful and operable. This article will introduce in detail how to use jQuery to remove input styles.

1. What is jQuery

jQuery is a popular JavaScript library that can greatly simplify tasks such as processing HTML documents, handling events, handling animations and Ajax. jQuery is a tool focused on rapid development, and its lightweight code base makes it more suitable for modern Internet application development.

2. Remove the input style

1. First, we need to define a class to represent the appearance after we want to remove the input style. This class can contain any styles you feel are necessary, such as fonts, background colors, borders, etc. Here, we take .demo-class as an example to show how to implement the following code:

.demo-class {
background-color: #f7f7f7;
border: 1px solid #ccc;
color: #333;
font-size: 16px;
padding: 5px 10px;
}

2. After that, we need to use jQuery to add kind. For this task, we can use the following code:

$(document).ready(function(){
$('input').addClass('demo-class');
} );

3. The above code will add a .demo-class class to each input element in the document. This is a simple yet effective way to remove styles from input elements. Of course, this is just a small function in jQuery. There are other methods in jQuery to remove the style of input.

4. In some cases, a certain input box in the form has special style requirements. For example, a certain text box needs to use different text colors. In this case, we need to target this special input box. Redefine styles. For example, the following example:

.demo-class {
/ common styles for all input elements /
}
.special-class {
color: red;
}

5. In this example, we use id to define a special text input box, and use class to override the style of the text box. jQuery uses the following code to implement:

$(document).ready(function(){
$('input:not(#special-input)').addClass('demo-class ');
});

6. Now, except for specific input boxes, all other input boxes use the .demo-class style. For .single-class, the style we define will only take effect on the input box with the ID special-input.

Summary

By using jQuery to remove the input style, we can better control the aesthetics and operability of the form. Sometimes, we need to use some splicing methods to change the style of elements, and sometimes we need to use classes or IDs to override the default style of elements. In either case, jQuery can help us achieve the best results.
