如何从JSON数组中删除JSON对象？

Question

var alldesignationsarr = ['Employee','Manager'];

Answer 1

您可以使用desgdescarr.filter()：

＆＃13;

＆＃13;

var alldesignationsarr = ['Employee','Manager'];

var desgdescarr = [{
    "designation": {
        "name": "Employee",
        "ptest": {}
    },
    
    "designation": {
        "name": "Manager",
        "ptest": {}
    },
    "designation": {
        "name": "Managers",
        "ptest": {}
    }
}];
    
var res = desgdescarr.filter((obj) => alldesignationsarr.indexOf(obj.designation.name) === -1);
console.log(res);

如果您想对原始数组进行更改，那么您也可以使用简单的forEach逻辑：

＆＃13;

＆＃13;

var alldesignationsarr = ['Employee','Manager'];

var desgdescarr = [{
    "designation": {
        "name": "Employee",
        "ptest": {}
    },
    
    "designation": {
        "name": "Manager",
        "ptest": {}
    },
    "designation": {
        "name": "Managers",
        "ptest": {}
    }
}];
    
desgdescarr.forEach((obj, index) => {
  if(alldesignationsarr.indexOf(obj.designation.name) !== -1){
    desgdescarr.splice(index,1);
  }
});

console.log(desgdescarr);
