数据赋值处理

// 数据赋值的简化处理方法：

// 1-将后台数据data下的值赋给condition下的data数组下的对象的value值，
var condition1 = 
    data:[
        name:‘***‘, value:‘1‘,
        name:‘****‘, value:‘2‘
    ]

var dataSource1 = 
    name:‘11‘,
    contactName:‘1122‘

const dataKey1=  [‘aa‘, ‘bb‘];
dataKey1.forEach(function (key, index) 
    condition1.data[index].value = dataSource1[key]
);
console.log(condition1, ‘condition1‘)
//  data:[  name: ‘***‘, value: undefined , name: ‘****‘, value: undefined  ]  ‘condition1‘

// 2-将后台数据data下的值赋给condition下的data对象的属性值，
var condition2 = 
    name:‘‘,
    contactName:‘‘

var dataSource2 = 
    name:‘2211‘,
    contactName:‘2222‘

const data=  [‘name‘, ‘contactName‘];
data.forEach(function (key) 
   condition2[key] = dataSource2[key]
);
console.log(condition2, ‘condition2‘) 
 // name: ‘2211‘, contactName: ‘2222‘  ‘condition2‘

// 3-将后台数据data下的值赋给condition下的data对象的属性值，若属性名称不同
// 可以在设置属性名时以对象形式定义
var condition3 = 
    name1:‘‘,
    contactName1:‘‘

var dataSource3 = 
    name:‘11‘,
    contactName:‘22‘

const dataKey3=  [‘name1‘:‘name‘, ‘contactName1‘:‘contactName‘];
dataKey3.forEach(function (item) 
    for(var key in item)
        condition3[key] = dataSource3[item[key]]
    
);
console.log(condition3, ‘condition3‘)
//  name1: ‘11‘, contactName1: ‘22‘  ‘condition3‘

// 4-将后台数据data下的值赋给condition下的data对象的属性值，若属性名称不同
// 可以在设置属性名时以对象形式定义,两个key区分定义
var condition4 = 
    name1:‘‘,
    contactName1:‘‘

var dataSource4 = 
    name:‘411‘,
    contactName:‘422‘

const dataKey4=  [key1:‘name1‘,key2:‘name‘, key1:‘contactName1‘,key2:‘contactName‘];
dataKey4.forEach(function (item) 
    condition4[item.key1] = dataSource4[item.key2]
);
console.log(condition4, ‘condition4‘)
//  name1: ‘411‘, contactName1: ‘422‘  ‘condition4‘
