vue date control changes length and width

Preface

In vue, the date control is one of the very important components. The date control can not only conveniently select dates, but also implement date formatting and custom component styles. In actual development, we often encounter situations where we need to change the length and width of date controls. This article will introduce how to change the length and width of the date control through props and css style adjustment of the vue component.

1. Use props to change the length and width of the date control

In vue, props is a way to pass data to components. It can pass various types of data from parent components to child components. . Common props types include strings, numbers, Boolean, objects, arrays, etc. We can implement the function of changing the length and width of the date control by defining props in the component. The specific steps are as follows:

1. Define props in the sub-component Datepicker.vue:

props: {
  width: {
    type: Number,
    default: 150
  },
  height: {
    type: Number,
    default: 35
  }
}

Two props are defined in this component: width and height, which represent the width and height of the date control respectively. Among them, the default values ​​of width and height are 150 and 35 respectively.

2. Use props in the template of the Datepicker.vue component

To use props in the template, you can pass the props value passed by the parent component through the v-bind instruction, and Use the style attribute to set the width and height of the date control:

In the template, use the v-bind directive to bind the width and height values ​​passed from the parent component to the style of the current component. Among them, ':style="{width: width 'px', height: height 'px'}" means to use inline styles to set the width and height of the control. In this way, the length and width of the date control can be changed through the props passed by the parent component.

3. Pass the width and height values ​​​​in the parent component

In the parent component, you can set the width and height values ​​​​through the properties of the component tag. In this way, different width and height values ​​can be passed in different parent components to achieve flexible adjustment of the length and width of the date control.

In the parent component, use the datepicker component and set the width to 200 and the height to 40 through the properties. This allows for universal changes to the length and width of the date control.

2. Use css styles to change the length and width of the date control

In addition to using props to change the length and width of the date control, we can also adjust the length and width of the date control through css styles. . The advantage of this method is that the length and width of the date control can be adjusted more flexibly, but it requires manually adding css styles to the component, which is more troublesome. The following are the specific steps:

1. Define the style of the date control

Add the css style in the Datepicker.vue component, as follows:

Set the control The width is 150px and the height is 35px.

2. Override the style in the parent component

In the parent component, override the style of the child component by adding a class attribute to the datepicker component:

In this way, the style of the child component can be overridden in the parent component and the length and width of the date control can be adjusted.

Summary

In vue, the date control is one of the very important components. The length and width of the date control can be changed through props and css styles. The use of props is relatively simple. The width and height of the control are passed and set through the v-bind directive and style attribute in the template. The use of css styles requires adding styles manually, which is relatively troublesome, but more flexible. Through these two methods, we can choose a more appropriate method according to actual development needs to adjust the length and width of the date control.
