使用AJAX将PHP变量发送到javascript
问题描述：
我有两个PHP变量，我想使用AJAX传递给javascript.
I have two PHP variables that I want to pass to javascript using AJAX.
test.php
$Longitude = json_encode($Long);
$Latitude = json_encode($Lat);
Index.js
$.ajax({
type: 'POST',
dataType: "json",
url:'test.php',
data:
success: function(data)
{
console.log("testing");
}
});
我是编程新手.请指导如何在ajax调用中引用这些变量名称.
I am new to programming. Please guide how to refer these variable names in the ajax call.
答
传入数组并对其进行编码.
Pass in array and encode it.
test.php
$data = ['Longitude ' =>$Long, 'Latitude ' => $Lat ];
echo json_encode($data);
index.js
$.ajax({
type: 'POST',
dataType: "json",
url:'test.php',
data:
success: function(data)
{
try {
data = JSON.parse(data);
}catch(e) {}
console.log(data);
}
});
