嗨,我正在寻求帮助
我正在学习如何使用Ajax和PHP,我想要做的是在PHP中运行查询并将结果存储在JSON中。
然后我想要echo
JSON并将其值设置为文本字段。
这可能吗?
因为我是Ajax和jQuery的新手,所以我不知道如何做到这一点 我试图这样做,但我只得到数组的第一个值。
这是我的代码:
<input type="text" id="text1">
<button type="button" class="btn btn-success" id="send">Success Button</button>
<input type="text" id="text2">
<input type="text" id="text3">
<input type="text" id="text4">
<script type="text/javascript">
$(document).ready(function(){
$("#send").click(function(event){
event.preventDefault();
var Rfc=$("#text1").val();
$.ajax({
type: 'POST',
url: 'search.php',
data: 'Rfc='+Rfc,
dataType : 'json',
success: function(msg){
var datashow = JSON.parse(msg);
$("#text2").val(msg[0].id_person); ///this is the only value that i get
$("#text3").val([1].person_name); ///i want to get the person's name here
$("#text4").val([2].person_address);///i want to get the person's address here
},
error : function () {
alert("error");
}
});
});
});
</script>
这是我的PHP文件:
<?php
$rfc=$_POST['Rfc'];
$connection = mysqli_connect("localhost","root","","transferorders");
$query = mysqli_query($connection,"SELECT * FROM person where rfc_number ='$rfc'");
$Data = array();
while($row = mysqli_fetch_assoc($query)){
$Data[]=$row;
echo json_encode($Data);
}
?>
这是我在控制台中得到的
未捕获的TypeError:无法读取未定义的属性“person_name” 在Object.success(测试ajax1.php:40)
答案 0 :(得分:0)
<?php
$rfc=$_POST['Rfc'];
$connection = mysqli_connect("localhost","root","","transferorders");
$query = mysqli_query($connection,"SELECT * FROM person where rfc_number ='$rfc'");
$row = mysqli_fetch_array($query)
$Data = '{"id":"'.$row['id_person'].'", "name":"'.$row['person_name'].'", "address":"'.$row['person_address'].'"}';
echo json_encode($Data);
?>
和脚本:
success: function(msg){
var datashow = JSON.parse(msg);
$("#text2").val(datashow["id"]); ///this is the only value that i get
$("#text3").val(datashow["name"]); ///i want to get the person's name here
$("#text4").val(datashow["address"]);///i want to get the person's address here
},
我希望它有所帮助!
