问题是您的JavaScript,我认为这是在另一个文件中,不知道PHP。您可以执行以下操作以在JavaScript变量中定义
$ID
<html>
<body>
<a id="addTofav">Add me to fav</a>
<?php
error_reporting(0);
include("config.php");
(is_numeric($_GET['ID'])) ? $ID = $_GET['ID'] : $ID = 1;
$result = mysqli_query($connect,"SELECT*FROM ".$db_table." WHERE idhome = $ID");
while($row = mysqli_fetch_array($result)):
$price=$row['price'];
$rent=$row['rent'];
$room=$row['room'];
$date=$row['date'];
echo"price";
echo"room";
echo"date";
endwhile;
?>
<!-- This part is what you want -->
<script>
var favID = <?php $ID ?>; // this gets the variable from PHP and saves it in the javascript variable.
document.cookie = 'my_id='+favID+'; expires=Fri, 3 Aug 2001 20:47:11 UTC; path=/' // save it to a cookie
</script>
<!-- till here -->
</body>
</html>
var nameEQ = "my_id=";
var ca = document.cookie.split(';');
var retrieved_id = null
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) retrieved_id = c.substring(nameEQ.length,c.length);
}
console.log(retrieved_id) // here you will find your ID
现在我还没有测试过。从理论上讲,它应该起作用。
查找您的要求后, 你应该移动这个
$ID = $_GET['ID'] : $ID = 1;
在JavaScript方面。如您所说,您想要更好的清洁代码。 您应该使用JavaScript访问从URL传递的参数。
var query = window.location.search.substring(1);
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
var ID = (pair[0]=='ID' ? pair[1] :1)
}
then ID很容易适用于您的js.您的JS:
$(function(){
var favID;
var query = window.location.search.substring(1);
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
var favID = (pair[0]=='ID' ? pair[1] :1)
}
$(document.body).on('click','#addTofav',function(){
var fav = {'$ID':favID};
faves.push(fav);
var stringified = JSON.stringify(faves);
createCookie('favespages', stringified);
location.reload();
});
您可以使用localstorage。 在当前页面
`localStorage.getItem('ID',10)`
在您想访问它的其他页面上。
localStorage.getItem('ID');
感谢我所有的朋友(Riyaj Khan和Anubhav),最后我得到了答案。替换此JavaScript代码而不是问题JavaScript,您会发现它的工作方式就像char.ch。此U代码可以在cookie中保存ID,然后在您想要的任何地方检索它
