Jsons to JS arrays

本文关键字：arrays JS to Jsons | 更新日期: 2023-09-27

我在php中有一个JSON数组，我想做的是将其作为两个数组传递给java脚本

[{"mon":"January","total":"29674"},{"mon":"February","total":"22956"},{"mon":"March","total":"35893"},{"mon":"April","total":"64003"},{"mon":"May","total":"43047"},{"mon":"June","total":"44613"},{"mon":"July","total":"72003"},{"mon":"August","total":"116742"}]

这里的数组应该是这样的，

          var s1 = [January, February, March, April , ....];
          var s2 = [29674, 22956, 35893, 64003, .....];

很抱歉，到目前为止我还不知道如何使用jsfiddle。解决方案如下：

var b = [{"mon":"January","total":"29674"},{"mon":"February","total":"22956"},{"mon":"March","total":"35893"},{"mon":"April","total":"64003"},{"mon":"May","total":"43047"},{"mon":"June","total":"44613"},{"mon":"July","total":"72003"},{"mon":"August","total":"116742"}]
var x = [], y = [];
for (i = 0; i < b.length; i++){ x.push(b[i].mon); y.push(b[i].total) }

结果：

["January", "February", "March", "April", "May", "June", "July", "August"]
["29674", "22956", "35893", "64003", "43047", "44613", "72003", "116742"]

因此，首先必须在第一个数组上循环，并将其保存在单独的数组中。

<?php 
    $input = '[{"mon":"January","total":"29674"},{"mon":"February","total":"22956"},{"mon":"March","total":"35893"},{"mon":"April","total":"64003"},{"mon":"May","total":"43047"},{"mon":"June","total":"44613"},{"mon":"July","total":"72003"},{"mon":"August","total":"116742"}]';
    $inputArray = json_decode($input, true);
    $s1 = array();
    $s2 = array();
    foreach ($inputArray as $row) {
        $s1[] = $row['mon'];
        $s2[] = (int) $row['total'];
    }
 ?>

然后你必须将它们打印在你的脚本中：

<script>
    var s1 = <?php echo json_encode($s1); ?>;
    var s2 = <?php echo json_encode($s2); ?>;
</script>
