Example of application scenario: If the display content of a certain cell on the page is required to be "only yes", "no" and "other", and the data passed or required to be passed by the backend corresponds to " 0", "1", "2", at this time, you need to use the filter function to filter and display.
The function definition is as follows:
convertToText(value) {
const valueMap = {
0: 'Yes',
1: 'No',
2: 'Other'
};
return valueMap[value] || value;
}
Page application:
<template slot="read">{ { flowModel.fete | convertToText }}</template>
Note: The filter() method creates a new array, and the elements in the new array are checked by checking the conditions in the specified array
All elements, without changing the original array.
