条件：arrA，arrB，通过对比修改arrB中的字段值

var sSrr = [];
var arrA = [
    {name:'这是一',Id:1},
    {name:'这是二',Id:2},
    {name:'这是三',Id:3},
    {name:'这是一',Id:1},
    {name:'这是二',Id:2}
]
var arrB = [
    {name:'这是二',Id:2},
    {name:'这是三',Id:3}
]
arrA.forEach(i=>{
    sSrr.push(i.name+i.Id)
})
arrB.forEach(r=>{
    if([...new Set(sSrr )].indexOf(r.name+r.Id)>-1){
        r.disabled = true
    }else{
        r.disabled = false
    }
})
