uniapp change radio button

Uniapp is a powerful and easy-to-use cross-platform application development framework that can be used to develop Android, iOS and Web applications. For Uniapp developers, it is very important to know how to change the radio button style. This article will focus on how to change the radio button box in Uniapp.

First of all, implementing the function of radio button in Uniapp mainly relies on the uni-radio component. This component can provide the display and selection functions of radio buttons. We can use the uni-radio component to change the style of the radio button.

Uni-radio components have two display methods, one is circular and the other is rectangular. If we want to change the radio button to our favorite style, we can do it by changing the style of the uni-radio component.

Let's look at an example below, assuming we have a uni-radio component:

<uni-radio :value="value" @change="changeRadio"></uni-radio>

value is the value of the radio button, and changeRadio is the callback function for the change of the radio button selection.

Now we want to change it to green style, we can add the following code in the style sheet:

.uni-radio .uni-radio-inner{
    background-color:#66CDAA;
    border: 2px solid #66CDAA;
}
.uni-radio .uni-radio-inner::after{
    background-color:#fff;
    border: 2px solid #66CDAA;
}

This implements the style change of the radio button box.

If we want to change the shape of the radio button from a circle to a rectangle, we can do it by changing the style of the uni-radio component. We can add the following code to the style sheet:

.uni-radio .uni-radio-inner{
    border-radius: 0px;
}
.uni-radio .uni-radio-inner::after{
    border-radius: 0px;
}

This will change the shape of the radio button to a rectangle.

In addition to changing the style of the radio button, we can also implement some other functions. For example, change the default selection of a radio button. We can achieve this by setting the checked attribute of the uni-radio component. The sample code is as follows:

<uni-radio :value="value" @change="changeRadio" :checked="checked"></uni-radio>

Among them, checked is a Boolean value indicating whether the radio button is selected.

To summarize, Uniapp provides the uni-radio component to implement the radio button function. We can change the radio button style by changing the style of the uni-radio component, or by setting the uni-radio component The checked attribute is used to change the default selected item of the radio button. I hope this article can help Uniapp developers better master the use of radio buttons and further improve the efficiency of application development.
