我从php / mysql数据库查询中获取了一个json多维数组(作为$ .ajax调用的成功函数中的“data”)。 PHP脚本将其发送到javascript文件,如下所示:
header('Content-Type: application/json');
echo json_encode($arr);
查询可以从数据库中返回一个或多个记录。
console.log(data)似乎只给了我“父”数组中的第一个“子”数组。这是控制台中的内容:
[{id:114, branchStateCovered:MN, branchCountyCovered:Aitkin,…},...]
0: {id:114, branchStateCovered:MN, branchCountyCovered:Aitkin,…}
1: {id:115, branchStateCovered:MN, branchCountyCovered:Benton,…}
2: {id:116, branchStateCovered:MN, branchCountyCovered:Carlton,…}
3: {id:117, branchStateCovered:MN, branchCountyCovered:Chisago,…}
4: {id:118, branchStateCovered:MN, branchCountyCovered:Cook,…}
5: {id:119, branchStateCovered:MN, branchCountyCovered:Crow Wing,…}
6: {id:120, branchStateCovered:MN, branchCountyCovered:Isanti,…}
7: {id:121, branchStateCovered:MN, branchCountyCovered:Itasca,…}
8: {id:122, branchStateCovered:MN, branchCountyCovered:Kanabec, branchZipCodesCovered:56358, 55051}
9: {id:123, branchStateCovered:MN, branchCountyCovered:Lake,…}
10: {id:124, branchStateCovered:MN, branchCountyCovered:Mille Lacs,…}
11: {id:125, branchStateCovered:MN, branchCountyCovered:Pine,…}
12: {id:126, branchStateCovered:MN, branchCountyCovered:Saint Louis,…}
13: {id:127, branchStateCovered:WI, branchCountyCovered:Douglas,…}
在另一个$ .ajax调用中,我正在使用
访问始终是一维的数组$('label#branchName').text(data['name']);
$('label#branchAddress').text(data['address']);
etc...
但在这种情况下,我需要遍历每个数组,并以与上面类似的方式显示每个数组。
我找到this SO post,但看起来帖子的作者正在创建数组,因为他知道每个“子”数组的“名称”(生产者)。也许我的答案就在那篇文章中,我只是没有看到它。
如何获取输出的多维数组并循环显示每个数组的数组到表中 - 或者我想在HTML端用它做什么?
答案 0 :(得分:3)
在success
来电的$.ajax()
回调中,data
是数组,因此您可以使用$.each()
进行迭代:
$.each(data, function(index, element) {
// use individual element (an object) here, i.e. element.id to get the id
});
