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‘
