我使用$ .post从数据库中检索数据，并在每一轮我调用函数add来追加某个div。问题是数据不按顺序排列。我该如何解决？请帮忙

Answer 1

如果可能的话，试试这个：

function selectDiv() {
 <?php  $stmt = $conn->prepare("SELECT id , name, t2.type  FROM data INNER JOIN t2 ON join_condition1”);
 $stmt->execute(); 
 $stmt->bind_result($id ,$name);
 while($stmt->fetch()) {?>
 add (<?php echo "'$id'";?>, <?php echo "'$name’”;?>, <?php echo "'$type’”;?>);
 <?php } ?>
 }

function add (id , name, type){
document.getElementById("div").innerHTML += name + "<br>" + "|"+ type + "<br>";
}

ajax按顺序返回数据库中的数据
