今天就跟大家聊聊有关使用js实现操作两个json数组合并、去重，以及删除某一项元素，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

两个json数组合并去重，以及删除某一项元素

let ha = [
 {id:'H',name:'3'},
 {id:'A',name:'6'},
 {id:'B',name:'14'},
 {id:'C',name:'60'}
 ];

let hb= [ 
 {id:'H',name:'2'},
 {id:'A',name:'6'},
 {id:'B',name:'16'}, 
 {id:'N',name:'2'},
 {id:'C',name:'19'}
 ];

// 合并两个json数组，并去重;

ha= Object.assign([], ha, hb);
console.log('ha',ha);

// [ 
 {id:'H',name:'2'},
 {id:'A',name:'6'},
 {id:'B',name:'16'}, 
 {id:'N',name:'2'},
 {id:'C',name:'19'}
 ];


// 去除json数组中的某一项

ha.splice(3, 1);
console.log('ha',ha);

// [ 
 {id:'H',name:'2'},
 {id:'A',name:'6'},
 {id:'B',name:'16'}, 
 {id:'C',name:'19'}
 ];
