Question

styleArr = data.items[0].companys_self_type_styleid.split(',')
matArr = data.items[0].companys_self_type_matid.split(',')
fieldArr = data.items[0].companys_self_type_fieldid.split( ',')

Y a-t-il un moyen simple de l'écrire

Answer 1

[styleArr, matArr, fieldArr] = [styleArr, matArr, fieldArr].map((key, index) => 
data.items[0]["companys_self_type" + [
    "styleid", "matid", "fieldid"
][index]].split(','))

Answer 2

function deal(n){
return data.items[0].n.split(',')
}
styleArr = deal(companys_self_type_styleid);
matArr = deal(companys_self_type_matid);
fieldArr = deal(companys_self_type_fieldid);

Answer 3

var data = {};
for (var prop in data.items[0]) {
  var i = prop.substring(prop.lastIndexOf('_') + 1, prop.lastIndexOf('id')) + 'Arr';
  data[i] = data.items[0][prop].split(',');
}

Answer 4

var arr = data.items[0].companys_self_type_styleid.split(',');
var styleArr,matArr,fieldArr
styleArr = matArr = fieldArr = arr ;
