通过键，JavaScript组合JSON数组

通过键，JavaScript组合JSON数组

如果要编写它以便可以接受任意数量的数组，而不仅仅是2个，则可以利用arguments，并执行以下 *** 作：

var json1 = [{id:1,name:'aaa'},{id:5,name:'ccc'},{id:3,name:'bbb'}];var json2 = [{id:3,parameter1:'x', parameter2:'y', parameter3:'z'}, {id:1,parameter1:'u', parameter2:'v', parameter3:'w'}, {id:5,parameter1:'q', parameter2:'w', parameter3:'e'}];function joinObjects() {  var idMap = {};  // Iterate over arguments  for(var i = 0; i < arguments.length; i++) {     // Iterate over individual argument arrays (aka json1, json2)    for(var j = 0; j < arguments[i].length; j++) {       var currentID = arguments[i][j]['id'];       if(!idMap[currentID]) {          idMap[currentID] = {};        }       // Iterate over properties of objects in arrays (aka id, name, etc.)      for(key in arguments[i][j]) {          idMap[currentID][key] = arguments[i][j][key];      }    }  }  // push properties of idMap into an array  var newArray = [];  for(property in idMap) {    newArray.push(idMap[property]);  }  return newArray;}var json3 = joinObjects(json1, json2);

这是一个工作中的prepen。
