如何将xmlhttp.responseText转换为js数组

这是我的{"name":"Eswara Manikanta Varma","email":"eswar1251@gmail.com","mobile":"9966578911"}来自xmlhttp.responseText，所以现在我要转换为js数组.. 当我警告var对象时，警报看起来像这样[object Object] 我想将其打印为jsarray [mobile]

第2页：

<?php
$q = $_GET['q'];
$con = mysqli_connect('localhost','root','enter','esmart');
if (!$con)
 {
 die('Could not connect: ' . mysqli_error($con));
 }

mysqli_select_db($con,'esmart');
$sql="SELECT * FROM suppliers WHERE name LIKE '%$q%'";

$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result))
 {
    $x['name']=$row['name'];
    $x['email']=$row['email'];
    $x['mobile']=$row['mobile'];
 }
echo json_encode($x);

mysqli_close($con);
?>

Answer 1

我认为您的问题出在PHP代码中。有了这个：

while($row = mysqli_fetch_array($result))
 {
    $x['name']=$row['name'];
    $x['email']=$row['email'];
    $x['mobile']=$row['mobile'];
 }
echo json_encode($x);

您将只获得查询的最后一行。为了能够得到一个数组，你可能需要这样的东西：

$response = array();
while($row = mysqli_fetch_array($result))
 {
    $x['name']=$row['name'];
    $x['email']=$row['email'];
    $x['mobile']=$row['mobile'];
    $response[] = $x;
 }
echo json_encode($response);

现在你将获得[{"name":"Eswara Manikanta Varma","email":"eswar1251@gmail.com","mobile":"9966578911"}, ...]，在JSON.parse之后它将是一个对象数组。

Answer 2

尝试使用：

mysqli_fetch_assoc（$结果）

而不是

mysqli_fetch_array（$结果）
