[英]Call PHP function with jquery $.ajax return json
How can I call (if even possible) a PHP function from javascript targeting one method just like ASP.NET. 如何从javascript中调用(如果可能的话)来自javascript的PHP函数,就像ASP.NET一样。
PHP: PHP:
...
function a($some_string){
return json_encode(array(
"username" => "bob",
"items" => array(
"item1" => "sandwich",
"item2" => "applejuice"
)
));
}
JS: JS:
$.ajax(
{url:"index.php/a",
type:"POST",
contentType:"application/json; charset=utf-8",
data:{some_string:"blabla"},
dataType:"json",
success:function(data){
alert(data);
},
error:function(a,b,c){
}
});
In C#: 在C#中:
[WebMethod()]
[ScriptMethod(ResponseFormat=ResponseFormat.Json)]
public static object a(string some_string)
{
return new {
user_name = "bob",
items = new {
item1 = "sanwitch",
item2 = "applejuice"
}
};
}
Thanks, 谢谢,

You can just put that one function in a PHP file alone. 您可以将一个函数单独放在PHP文件中。 Then run the function within that file (so it echoes out the JSON). 然后在该文件中运行该函数(因此它回显JSON)。 Have ajax call that file. 让ajax调用该文件。
In your case: 在你的情况下:
echo a($string);
If you were willing to explore an alternative to Jquery, there is a tool called XAJAX that allows you to directly call PHP functions asynchronously via AJAX. 如果您愿意探索Jquery的替代方法,那么有一个名为XAJAX的工具允许您通过AJAX异步直接调用PHP函数。 It's a pretty nifty tool, though the support and forums are a bit cryptic. 这是一个非常漂亮的工具,虽然支持和论坛有点神秘。 For those who are hardcore PHP (but not JAVASCRIPT) guys, this tool is a great option. 对于那些硬核PHP(但不是JAVASCRIPT)的人来说,这个工具是一个很好的选择。
