美食网站开发环境,如何建设一个手机网站,苏州seo推广,网店设计流程图问题#xff1a;数组对象去重
var arr [{name: ‘a’,id: 1}, {name: ‘a’,id: 2}, {name: ‘b’,id: 3}, {name: ‘c’,id: 4}, {name: ‘c’,id: 6}, {name: ‘b’,id: 6}, {name: ‘d’,id: 7}]; 对数组对象name进行去重处理#xff0c; 结果显示为#xff1a; [{name…问题数组对象去重
var arr [{name: ‘a’,id: 1}, {name: ‘a’,id: 2}, {name: ‘b’,id: 3}, {name: ‘c’,id: 4}, {name: ‘c’,id: 6}, {name: ‘b’,id: 6}, {name: ‘d’,id: 7}]; 对数组对象name进行去重处理 结果显示为 [{name: ‘a’,id: 1}, {name: ‘b’,id: 3}, {name: ‘c’,id: 4}, {name: ‘d’,id: 7}];
解决方式
var arr [{name: a,id: 1}, {name: a,id: 2}, {name: b,id: 3}, {name: c,id: 4},{name: c,id: 6}, {name: b,id: 6}, {name: d,id: 7}];
function deWeight() {for (var i 0; i arr.length - 1; i) {for (var j i 1; j arr.length; j) {if (arr[i].name arr[j].name) {arr.splice(j, 1);//因为数组长度减小1所以直接 j 会漏掉一个元素所以要 j--j--;}}}return arr;
}
var newArr deWeight();
console.log(%c%s, color:red;, 方法一es5,newArr, newArr);
