uniapp calendar settings cannot select dates

In recent years, with the rapid development of mobile applications, more and more developers choose to use the cross-platform framework uniapp for application development. In application development, it is often necessary to integrate calendar controls to facilitate users to select dates. This article will share with you how to set non-selectable dates in uniapp.

1. Using the calendar component in uniapp

Uniapp has a built-in calendar component, which can be used to quickly implement calendar display and date selection functions. We can introduce the calendar component into the page that needs to use the calendar:

<template>
  <view>
    <calendar @confirm="onConfirmDate" />
  </view>
</template>

<script>
  export default {
    methods: {
      onConfirmDate(e) {
        console.log(e.detail)
      }
    }
  }
</script>

Use the above code to display a calendar component with a confirmation button on the page. When the user selects a date, the confirm event will be triggered, and we can get the date selected by the user in this event.

2. Setting non-optional dates

In the calendar component of uniapp, it is actually very simple to set non-optional dates. You only need to pass in the disableDays attribute when using the component. The disableDays attribute is an array, each element of which is a date string, indicating that the date is a non-selectable date. The following is a specific code example:

<template>
  <view>
    <calendar :disableDays="disableDays" @confirm="onConfirmDate" />
  </view>
</template>

<script>
  export default {
    data() {
      return {
        disableDays: ['2021-08-01', '2021-08-02']
      }
    },
    methods: {
      onConfirmDate(e) {
        console.log(e.detail)
      }
    }
  }
</script>

In the above code, we use an array named disableDays to store non-selectable dates, which stores the two dates of August 1 and 2, 2021. When using the calendar component, we pass the disableDays array to the disableDays property of the component. In this way, these two days will be prohibited from selection in the calendar.

3. Other settings and precautions

In addition to the disableDays attribute, the uniapp calendar component also provides many other configuration options, which can be set by passing in the corresponding attributes. The following are some commonly used configuration options:

1. startDate: Set the starting date, dates before this date will not be selected;
2. endDate: Set the end date, the date after this date Will not be able to select;
3. confirmText: Set the text of the confirmation button;
4. markedDays: Set the dates that need to be marked, usually used to display dates that have been booked.

It should be noted that since uniapp uses the API of the mini program, after setting disableDays, you need to click on the blank area above the calendar or click the "OK" button for it to take effect. In actual use, you also need to pay attention to some date format issues. For example, the format of the date string should be "yyyy-MM-dd", otherwise it cannot be recognized correctly. In addition, there are some bugs in the uniapp calendar component, such as flickering problems on iOS, which require developers to pay attention.

To sum up, by setting the disableDays attribute, we can quickly and easily set the non-selectable dates in the uniapp calendar component, adding more flexibility and convenience to our application. Of course, in actual use, it is necessary to combine specific needs and set other attributes to meet the needs of users.
