.....
代码:
var alphaNumericArray = ['8a337e46-7d3f-46bc-b661-579f8d25fe09',
'09312d27-4ddc-458e-95dd-74531f787368',
'e7c5fba1-ce59-439a-a560-8f558e7c0ac4',
'1edcdde8-702e-4703-a505-ca81b77accdd',
'2f66ba6c-7fd2-4d52-8ed6-b0ee6d4d0310',
'7529217d-ee80-41eb-ade7-208674924ab9',
'523f4f75-8d0a-4ad1-8f40-e8bc679956be',
'80871291-c8de-47d9-9b02-3f8444c5d64e',
'7529217d-ee80-41eb-ade7-208674924ab9'];
alphaNumericArray.sort(function(a, b) {
a = a.value;
b = b.value;
return a-b;
});
//console.log(alphaNumericArray);
//alert(alphaNumericArray);
输出未排序。它在警报弹出窗口和控制台日志中显示相同的数组。
var alphaNumericArray = [
'8a337e46-7d3f-46bc-b661-579f8d25fe09',
'09312d27-4ddc-458e-95dd-74531f787368',
'e7c5fba1-ce59-439a-a560-8f558e7c0ac4',
'1edcdde8-702e-4703-a505-ca81b77accdd',
'2f66ba6c-7fd2-4d52-8ed6-b0ee6d4d0310',
'7529217d-ee80-41eb-ade7-208674924ab9',
'523f4f75-8d0a-4ad1-8f40-e8bc679956be',
'80871291-c8de-47d9-9b02-3f8444c5d64e',
'7529217d-ee80-41eb-ade7-208674924ab9'
];
alphaNumericArray.sort();
document.getElementById('out').textContent = JSON.stringify(alphaNumericArray, null, 2);
<pre id="out"></pre>
结果是:
[
"09312d27-4ddc-458e-95dd-74531f787368",
