js json中如何删除指定元素

Posted 2023-03-26

参考技术A 删除json下指定的元素
var obj = ‘id’:1, ‘name’:2;
delete obj.id;
delete obj[id];
console.log(obj); // ‘name’:2

删除数组中指定元素
var objArray = [‘1’,’2’,’3’,’4’];
objArray.remove(‘1’);
console.log(objArray); // [‘2’,’3’,’4’]
/*定义js数组删除元素/
Array.prototype.remove = function(val)
var index = this.indexOf(val);
if (index > -1)
this.splice(index, 1);
