存储一个AJAX查询结果JavaScript变量的每个值 [英] Store Each Value of a AJAX Query Result to Javascript Variables

问题描述

下面是一个jQuery Ajax的功能从PHP文件返回一些数据。

Here's a jQuery-ajax function that returns some data from a php file.

$('.up').click(function() {
    var act = $('.active').val();

    $.ajax({
        type: "POST",
        url: "database.php",
        data: {
            value: act
        }
    }).done(function(result) {
        $('#msg').html(result)
    });
});

我得到的查询结果数组。我有没有问题。

I get the array result of the query. I have no problem with.

PHP结果：

array(2) {
  [0]=> array(2) { ["Label"]=> string(3) "Group1" ["Count"]=> string(1) "244" }
  [1]=> array(2) { ["Status"]=> string(7) "Group2" ["Count"]=> string(1) "125" }
}

实际的查询结果是这样的。

Actual query result is this.

Label   Count
Group1  244
Group2  125

现在，我得到的结果。我想的计数列中的数字存储到两个不同的JavaScript变量。

Now that I get the result. I wanted to store the numbers of the Count column to two different javascript variables.

到目前为止，我已经尝试过这一点。

So far I tried with this.

var value1 = "<?php echo htmlentities($data[0]['Count']) ?>";
var value2 = "<?php echo htmlentities($data[1]['Count']) ?>";

试图与上述一块code替换为结果在Ajax调用。

但是，当我这样做的单击事件本身不会被触发。

But when I did this the click event itself was not triggered.

我已经保存了数以两个 PHP 变量即值1 和值2 。

I've saved the numbers to two php variables namely value1 and value2.

和在结果中的 AJAX 拨打我得到的结果类似 244125 。

And in the result of the ajax call i get the result like 244125.

帮我节省​​了数以两个不同的的JavaScript 变量。

Help me saving that number to two different javascript variables.

推荐答案

我假设你会做一些与此数据，因此你需要知道你正在寻找什么。

I am assuming you are going to do something with this data so you'll need to know what you are looking for.

让你的PHP来提供JSON有像这样的键：

Get your PHP to serve up JSON with keys like so:

{"Bob": "24", "Sue": "12"}

这种方式，您可以通过一大堆访问你需要的信息，或只是循环。我做了一个小提琴这我希望会帮助你理解。

This way you can access the information you need or just loop through the whole lot. I've made a little fiddle which I am hoping will help you understand.

最后你只是想使用jQuery的$ .getJSON拉的信息，然后解决它，但是你请。

Ultimately you simply want to use the jQuery $.getJSON to pull the information and then deal with it however you please.

如果您需要PHP来输出指定然后格式，你可以这样做：

If you need PHP to output in the format you specified then you can do:

$people = array("24", "12", "16", "48");
var_dump(json_encode($people));
