js数组便利根据某个属性值的范围获取新数组

Question

js里面有一个数组,数组长度为10，如何根据数组属性：eg:array[i].age小于15,得到新数组array1

Answer 1

 <script>
function isBig(element, index, array) {
    return (element.age < 15);
}
var srcArr = [];
srcArr.push({age:10});
srcArr.push({age:16});
srcArr.push({age:12});
srcArr.push({age:15});
var destArr= srcArr.filter(isBig);
for(var i=0;i<destArr.length;i++){
   alert(destArr[i].age);
}
</script>
