Question

我有一个PHP代码，可以从ms访问中获取数据并将其存储到$ jsonStr，例如：

$pivot_dataset = array();
   while(odbc_fetch_row($rs)) {
   // Push this data onto the end of the array
$pivot_dataset[] = array(
    'id' => odbc_result($rs,"id"),
    'year' => odbc_result($rs,"year"),
    'month' => odbc_result($rs,"month"),
    'empName' => odbc_result($rs,"empName"),
    'empPose' => odbc_result($rs,"empPos"),
    'numMc' => odbc_result($rs,"numMc"),
    'numLeave' => odbc_result($rs,"numLeave")
);
}

 odbc_close($conn);
 $jsonStr = json_encode($pivot_dataset); //[{"id": 1, "year": 2014 , "month": "JAN" ... }, { ... }];

但现在我想将$ jsonStr存储在javascript数据集中。所以我做这样的事情：

var pivot_dataset = <?php 
$conn = odbc_connect('pivot_test','','') or die ("Error in connection");
$sql = "select * from empDetails"; 
$rs = odbc_exec($conn,$sql);
if (!$rs)
{
  exit ("Error in Sql");
}
$pivot_dataset = array();
while(odbc_fetch_row($rs)) {
// Push this data onto the end of the array
$pivot_dataset[] = array(
    'id' => odbc_result($rs,"id"),
    'year' => odbc_result($rs,"year"),
    'month' => odbc_result($rs,"month"),
    'empName' => odbc_result($rs,"empName"),
    'empPose' => odbc_result($rs,"empPos"),
    'numMc' => odbc_result($rs,"numMc"),
    'numLeave' => odbc_result($rs,"numLeave")
);
}
odbc_close($conn);
$jsonStr = json_encode($pivot_dataset);
echo $jsonStr;
?>;

但它没有用，我希望javascript存储数据集如下：

var pivot_dataset = [{"id": 1, "year": 2014 , "month": "JAN", "empName": "David", "empPos": "engineer","numMc": 1, "numLeave": 2},];

有人可以请更正吗？我是新手。 TQ

就像

一样

var pivot_dataset = <?php echo $jsonStr;  ?>

不像你已经完成了整个逻辑：

var pivot_dataset = <?php 
$conn = odbc_connect('pivot_test','','') or die ("Error in connection");
$sql = "select * from empDetails"; 
$rs = odbc_exec($conn,$sql);
if (!$rs)
...........

首先执行PHP Logic然后将数据存储到您在$jsonStr;中完成的变量中，然后下一步是

<?php 
 $conn = odbc_connect('pivot_test','','') or die ("Error in connection");
 $sql = "select * from empDetails"; 
 $rs = odbc_exec($conn,$sql);
 if (!$rs)
    {
      exit ("Error in Sql");
    }
 $pivot_dataset = array();
 while(odbc_fetch_row($rs)) {
    // Push this data onto the end of the array
   $pivot_dataset[] = array(
    'id' => odbc_result($rs,"id"),
    'year' => odbc_result($rs,"year"),
    'month' => odbc_result($rs,"month"),
    'empName' => odbc_result($rs,"empName"),
    'empPose' => odbc_result($rs,"empPos"),
    'numMc' => odbc_result($rs,"numMc"),
    'numLeave' => odbc_result($rs,"numLeave")
  );
 }
 odbc_close($conn);
$jsonStr = json_encode($pivot_dataset);
?>

<script>
var pivot_dataset = <?php echo $jsonStr;  ?>
</script>

它。

将数据从php json存储到javascript数据集中
