Question

我试图从mySQL中获取一个列作为php中的数组，然后使用jquery / ajax将其读入javascript，最后在一些HTML div中显示数组的前四个。

我认为我有php工作，因为当我检查时，我得到一个包含数组中所有元素的返回。

retrieve.php

//Create connection ("Server", "Login name", "Password", "Database name")
$connect = mysql_connect($host, $username , $password); 
 //Check connection
if (!$connect)
{
    die ('could not connect: '. mysql_error());
}

//create connection and select database
mysql_select_db($database, $connect);

//select text column and orders them by most recent postID
$query = "SELECT text FROM $table ORDER BY postID DESC";
$result = mysql_query($query);

//create an array of recent responses
while($row = mysql_fetch_array($result)){
    echo json_encode($row['text']);
}

mysql_close($connect);

scripting.js

$(document).ready(function(){  //This performs specified actions when the page fully loads

$.ajax({
    type: 'POST',
    url: 'retrieve.php',
    data: 'data',
    dataType: 'json',
    success: function(result){
        $("#box0").html(result[0])
        $("#box1").html(result[1])
        $("#box2").html(result[2])
        $("#box3").html(result[3]);
    }
});

尝试替换

while($row = mysql_fetch_array($result)){
    echo json_encode($row['text']);
}

与

$rows = array();
while($row = mysql_fetch_array($result)){
    $rows[] = $row['text'];
}
echo json_encode($rows);

以json编码行文本数组，而不是单独编码。

用jquery读取php数组并附加到div？
