关于前端:取数组属性值相同数据-按照属性值分类组成新数组

数组数据

data = [    {name: "Z", detail: "zzz"},    {name: "W", detail: "wwww1"},    {name: "W", detail: "www2"},    {name: "W", detail: "www3"},    {name: "F", detail: "ff1"},    {name: "F", detail: "ff2"},    {name: "L", detail: "ll2"},    {name: "L", detail: "ll2"}  ]

办法转换

let listArr = [];data.forEach(function (val, index) {  for (var i = 0; i < listArr.length; i++) {      // 比照雷同的字段key，雷同放入对应的数组      if (listArr[i].name == val.name) {          listArr[i].features.push({              name: val.name,              detail: val.detail           });           return;      }  }  // 第一次比照没有参照，放入参照  listArr.push({      name: val.name,      detail: val.detail  });});
