求彻底删除JSON中一个元素的方法

[aubergines]

比如说

test1 = [{"name":"tank","total":"100"},{"name":"zhang","total":"23"},{"name":"hao","total":"325"}]; 

,请问怎样彻底删除干净某一个元素，比如

{"name":"tank","total":"100"},

或者是

,{"name":"hao","total":"325"}

，看清楚了需要把对应的

,

删除掉的。

var obj = {a:1, b:2};
delete obj.a;
console.log(obj);  // {b:2}

仔細一看，樓主不是要刪json的 而是array的元素…

var arr = [2,4,6,8];
//刪除2的話，先找出index在哪
var index = arr.indexOf( 2 ); //0
arr.splice(index, 1);
console.log(arr); //[4,6,8]

像樓主的情況要用for跑一次test 然後比對資料後找出index為多少再執行 arr.splice(index, 1);

var a= [{"name":"tank","total":"100"},{"name":"zhang","total":"23"},{"name":"hao","total":"325"}];
a=a.slice(0,2);
console.log(a);

var b={a:1,b:2};
delete b.a;
console.log(b);
