我想要做的是，我有一张名为酒店的桌子，我有一个页面，人们可以根据房间类别预订酒店。现在用于显示酒店我正在使用while循环，其中数据被提取，酒店显示在自动div中，所有人都相同。所以我添加了一个$i=1并添加到id字段中，$i在while循环结束时递增。
所以我得到的错误是我无法检索房间类别的费用。
这是我的代码：
获取个别酒店的PHP代码并以div显示。
<?php
include 'mysql.php';
$i = 1;
$query = mysql_query("SELECT * FROM hotels WHERE location = 'portblair' ") or die("the query cannot be completed at this moment");
if(mysql_num_rows($query) <1) {
die("no hotels found");
}
while($row = mysql_fetch_array($query, MYSQL_ASSOC)){
$hotel_name = $row['name'];
$hotel_type = $row['type'];
$hotel_location = $row['location'];
$hotel_cat1 = $row['cat1'];
$hotel_cat2 = $row['cat2'];
$hotel_cat3 = $row['cat3'];
$hotel_cat4 = $row['cat4'];
$hotel_cp = $row['cp'];
$hotel_map = $row['map'];
$hotel_ap = $row['ap'];
$hotel_em = $row['em'];
if($hotel_type == "0"){
$hotel_star ='<span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span>';

所以我想要一个js脚本，显示为各个酒店选择的房间类别的费用。
这是我的js代码：
function hotel_rate(){
jQuery(document).ready(function($){
var i=1;
var cnt = $("#count").val();
for(i=1;i<cnt;i++){
var cat = $("#hotel_cat["+i+"]").val();
var test = cat.split(:);
var cat_cost = parseInt(test[1]);
$("#add["+i+"]").html("Rs: "+cat_cost+" Add");
}
});
}
从控制台获取的错误是：“未捕获的ReferenceError：未定义hotel_rate”和“Uncaught TypeError：无法读取未定义的属性'split'。”
任何类型的帮助都会得到满足。 提前完成。

hotel_rate()的声明应该在内部就绪功能，也可以用cat.split(:);替换cat.split(':');：
$(function(){
function hotel_rate(){
var i=1;
var cnt = $("#count").val();
for(i=1;i<cnt;i++){
var cat = $("#hotel_cat["+i+"]").val();
var test = cat.split(':');
var cat_cost = parseInt(test[1]);
$("#add[1]").html("Rs: "+cat+" Add");
}
}
});

你的jquery文件必须是这样的
function hotel_rate(){ // just define the function.
var i=1;
var cnt = $("#count").val();
for(i=1;i<cnt;i++){
var cat = $("#hotel_cat["+i+"]").val();
var test = cat.split(':');
var cat_cost = parseInt(test[1]);
$("#add[1]").html("Rs: "+cat+" Add");
}
}
jQuery(document).ready(function($){
hotel_rate(); // fire it on document ready
});
此外，您错过var test = cat.split(:);中的引号，应该是var test = cat.split(':');
答案 2 :(得分：0)
以上两个答案也是对的。你必须在document.ready部分声明函数，并且split函数参数必须在其中包含字符串。
这里是我按照你的概念放置工作代码的例子。你也可以检查这个小提琴中的粘贴php fiddle。
<div class="col-md-3 col-xs-6">
<div class="panel panel-red">
<div class="panel-heading">
Hotel name </div>
<div class="panel-body">
<img src="images/hotels/Hotel name.png" class="img-responsive"/>
<div class="my-caption">
<span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span> </div>
<select name="hotel_cat" id="hotel_cat_1" class="form-control" onchange="hotel_rate()">
<option value="">Category</option>
<option value="1:50">1</option>
</select>
<span id="add[1]" >Add</span>
</div>
</div>
</div>
<input type="hidden" name="count" id="count" value="1"/>
<script>
function hotel_rate(){
var cat = document.getElementById("hotel_cat_1").value;
alert(cat);
var test = cat.split(':');
var cat_cost = parseInt(test[1]);
document.getElementById("add[1]").innerHTML="Rs: "+cat_cost+" Add";
}
</script>
并且你将猫的价值分成了＆＃39;：＆＃39;为了获得酒店的成本，所以你必须拥有以下价值：隔离。
