这个问题已在这里问了几次,但我还没有看到任何回复对我有用。
我有一段用cakePHP构建的代码,它成功地以JSON格式返回数据,但我还没有能够使用Javascript将这个JSON数据插入到HTML div中。
$('.book-click').click(function (e) {
e.preventDefault();
var getHotel = $(this).attr('hotel-id');
$.ajax({
type: "POST",
url: "<?php echo $this->Html->URL(array('action' => 'postBook')); ?>",
data: {
hotel: getHotel
},
cache: false,
dataTye: "json",
success: function (JSONObject) {
var myData = "";
for (var key in JSONObject) {
if (JSONObject.hasOwnProperty(key)) {
myData += JSONObject[key];
}
}
/*console.log(myData);*/
alert(myData[key]["hotelname"]); //Giving undifined in alert
}
});
});
这是我在浏览器控制台上记录数据时获得的JSON数据:
[
{
"id": "11",
"hotelname": "Sheraton hotel",
"hoteladdress": "Abule Ikeja",
"state": "Lagos State",
"lga": "Ikeja",
"hotelphone": "65645545454",
"hotelwebsite": "",
"adminphone": "6565656565",
"adminemail": "mail@hotel.com",
"hotelemail": "",
"facilities": ",,",
"roomscategory": "Diplomatic",
"standardrate": "150000",
"leanrate": "",
"aboutHotel": "",
"requestStatus": "0",
"createdOn": "1424360902",
"updatedOn": "1424360902"
}
]
如何成功将此JSON数据转换为HTML。像这样:
$('#myDiv').html(myData[key]["hotelname"]);
我试过这个,但它只是给了我Undefined
。
感谢任何帮助。

使用$.each()
进行迭代:
success: function (JSONObject) {
$.each(JSONObject, function(k,item){
$('#myDiv').html(item.hotelname);
});
}
var json = [
{
"id": "11",
"hotelname": "Sheraton hotel",
"hoteladdress": "Abule Ikeja",
"state": "Lagos State",
"lga": "Ikeja",
"hotelphone": "65645545454",
"hotelwebsite": "",
"adminphone": "6565656565",
"adminemail": "mail@hotel.com",
"hotelemail": "",
"facilities": ",,",
"roomscategory": "Diplomatic",
"standardrate": "150000",
"leanrate": "",
"aboutHotel": "",
"requestStatus": "0",
"createdOn": "1424360902",
"updatedOn": "1424360902"
}
]
$.each(json, function(i, item){
$('body').append(item.hotelname);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

根据您的错误,您似乎没有有效的json或者是json字符串。所以在loopin之前你必须解析它:
success: function (JSONObject) {
var data = $.parseJSON(JSONObject); // parse it
$.each(data, function(k,item){
$('#myDiv').html(item.hotelname);
});
}

var myData = "";
for (var key in JSONObject) {
if (JSONObject.hasOwnProperty(key)) {
myData += JSONObject[key];
}
}
myData
这里只是一个string
。因此,调用myData[key]["hotelname"]
将返回undefined,因为您正在尝试访问不存在的内容。
为什么不直接使用Ajax调用中的结果?
