我遇到了一个问题,无法将JavaScript变量发布到PHP文件中。请问有人能告诉我出了什么问题吗?
// Get Cookies
var getCookies = document.cookie;
cookiearray = getCookies.split(';');
SelectedIds = cookiearray[0];
//take key value pair
name = cookiearray[0].split('=')[0];
value = cookiearray[0].split('=')[1]; // The variable(values) i want to pass
// Create our XMLHttpRequest object
var hr = new XMLHttpRequest();
hr.open("POST", url, true);
var url = "page.php";
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
hr.onreadystatechange = function() {
if(hr.readyState == 4 && hr.status == 200) {
var return_data = hr.responseText;
document.getElementById("Comp").innerHTML = return_data;
}
}
hr.send(value); // Request - Send this variable to PHP
document.getElementById("Comp").innerHTML = "loading...";
PHP
$test = $_POST['value'];
print_r($test); // NULL
谢谢
var url = "page.php"
这一行应该在引用url
之前。(上面一行) - marekful
