now make a drop-down multi-selection, as shown in the figure, and the selected id is [2prime3]
.but the background requires the data to be like this:
[
{
"appId":2,
"direction":"1"
},
{
"appId":3,
"direction":"1"
},
]
where direction is always dead for 1, how can I change it to the format I want at the back end?
function handleData(data) {
let _data = data.map(item => {
return {
'appid': item,
'direction': '1'
}
})
return _data;
}
js to construct the array needed by the backend, foreach the array you get from the drop-down list (for example), put {appId:foreachItem,direction:1} in an array variable at a time, and finally pass the array to the backend
