Background profile.php Code:
Copy Code code as follows:
<?php
$arr = Array (
' FirstName ' => iconv (' gb2312 ', ' utf-8 ', ' not honest '),
' LastName ' => iconv (' gb2312 ', ' utf-8 ', ' Don't Disturb '),
' Contact ' => Array (
' Email ' => ' fcwr@jb51.net ',
' website ' => ' http://www.jb51.net ',
)
);
Converts an array of JSON
$json _string = Json_encode ($arr);
Notice here that double quotes can handle variables inside, and single quotes don't
echo "GetProfile ($json _string)";
?>
It should be pointed out that, in the UTF-8 encoding, the Chinese characters will not be encode, the result will come out null value, so if you use gb2312 to write PHP code, then you need to use Iconv or MB content to UTF-8 and then Json_encode.
Front index.html Code:
Copy Code code as follows:
<script type= "Text/javascript" >
function GetProfile (str) {
var arr = str;
document.getElementById ("FirstName"). InnerHTML = Arr.firstname;
}
</script>
<body>
<div id= "FirstName" ></div>
</body>
<!--use JSON to implement Cross-domain data calls, where "profile.php" is changed to "http://another domain/profile.php" to see the Cross-domain-->
<script type= "Text/javascript" src= "profile.php" ></script>
Assigning JSON-formatted data directly to a variable in JavaScript becomes an array, which makes it easy to manipulate, and the next step is inconvenient if you use XML as a data transfer.
Obviously, when Index.html calls Profile.php, the JSON string is generated and passed in GetProfile as a parameter, and then the nickname is inserted into the Div, so that a cross-domain data interaction is completed
Call index.html
Output: Non-prudential
