我必须传递Json数据，该数据是在将信息插入数据库表后生成的，现在我必须将该信息传递到其他页面BookingConformation.html.
例如，我们将获得表单服务器欢迎Mittel先生/夫人感谢您预订家庭服务，您的预订id是1。所以请告诉我如何传递信息，这是javascript中的表单服务器，现在我必须将此信息传递到其他页面，请帮我。
脚本
<script>
$(document).ready(function(){
$("#register-form").validate({
rules: {
userName: "required",
email: {
required: true,
email: true
},
userContactNumber: "required"
},
messages: {
userName: "Please enter your Name",
userContactNumber: "Please enter your Mobile number",
email: "Please enter a valid email address",
},
submitHandler: function(form) {
var uName = $('#userName').val();
var mailId = $('#email').val();
var mobNum = $('#userContactNumber').val();
$.ajax({
url:"http://localhost/bookRoom/book.php",
type:"POST",
dataType:"json",
data:{type:"booking", Name:uName, Email:mailId, Mob_Num:mobNum},
ContentType:"application/json",
success: function(response){
//alert(JSON.stringify(response));
//alert("success");
alert(response);
var globalarray = [];
globalarray.push(response);
window.localStorage.setItem("globalarray", JSON.stringify(globalarray));
window.location.href = 'BookingConformation.html';
},
error: function(err){
window.location.href = 'error.html';
}
});
return false; // block regular submit
}
});
});
</script>

如果这是您真正的服务器端代码，那么。。。它完全不安全。您不应该将用户发布的变量直接传递到查询中。
$query2 = "insert into booking(cust_email, cust_mobile, cust_name) values('$mail','$mobile','$name')";
至少使用"mysql_real_eescape_string"转义这些值，或者使用准备好的语句。和不要再使用mysql，使用mysqli，它与您正在使用的几乎相同，但不会很快被弃用。
此外，您正在对一个不需要json编码的字符串进行json编码，它只是一段文本，不是有效的json代码。这可能就是为什么@SimarjeetSingh Panghlia的答案对你不起作用。
对结构化数组进行编码，而不是对该值进行jsonencoding。
$response = array( "status" => true );
if(isset($_POST['type']))
{
if($_POST['type']=="booking"){
$name = mysql_real_escape_string( $_POST ['Name'] ));
$mobile = mysql_real_escape_string($_POST ['Mob_Num']);
$mail = mysql_real_escape_string($_POST ['Email']);
$query1 = "insert into customer(userName, userContactNumber, email) values('$name','$mobile','$mail')";
$query2 = "insert into booking(cust_email, cust_mobile, cust_name) values('$mail','$mobile','$name')";
$result1 = mysql_query($query1);
$result2 = mysql_query($query2);
$id = mysql_insert_id();
$response["message"] = "Welcome Mr/Mrs ".$name." Thanks for booking home services your booking id is = ".$id;/* make sure you strip tags etc to prevent xss attack */
}
}
else{
$response["status"] = false;
$response["message"] = "Invalid format";
}
echo json_encode($response);
/* Note that you are making the query using ContentType:"application/json", */
这意味着无论查询是否成功，都应该使用json进行响应。我还建议使用一个名为jStorage的简单jQuery插件，它可以轻松地获取/设置对象，而无需序列化它们。
您可以使用sessionStorage来存储和检索JSON数据。
var complexdata = [1, 2, 3, 4, 5, 6];
// store array data to the session storage
sessionStorage.setItem("list_data_key", JSON.stringify(complexdata));
//Use JSON to retrieve the stored data and convert it
var storedData = sessionStorage.getItem("complexdata");
if (storedData) {
complexdata = JSON.parse(storedData);
}
使用sessionStorage.clear(); 后删除会话存储数据
你可以试试这个
在第一页上声明变量
<script type="text/javascript">
var globalarray = [];
globalarray.push(response.d);
window.localStorage.setItem("globalarray", JSON.stringify(globalarray));
</script>
调用第二页上的变量
<script type="text/javascript">
var globalarray = [];
var arrLinks =[];
arrLinks = JSON.parse(window.localStorage.getItem("globalarray"));
console.log(arrLinks);
</script>
