This is a simple POST request function to replace the complex $.ajax. The callback function can be called when the request is successful. If you need to execute a function on error, use $.ajax. Sample code:
Ajax.aspx:
Response.ContentType = "application/json";Response.Write("{result: '" + Request["Name"] + ",you OK! (This message comes from the server)'}"); jQuery code:
$.post("Ajax.aspx", { Action: "post", Name: "lulu" }, function (data, textStatus){ // data can be xmlDoc, jsonObj, html, text, etc. // this; // For the option configuration information of this Ajax request, please refer to this mentioned in jQuery.get() alert(data .result); }, "json"); Click to submit:

$.ajax() This is the bottom layer of jQuery AJAX implementation. For simple and easy-to-use high-level implementations, see $.get, $.post, etc.
There are several Ajaxeventparameters: beforeSend, success, complete, error. We can define these events to handle each of our Ajax requests well.
$.ajax({url: 'stat.php',
type: 'POST',
data:{Name:"keyun"},
dataType: 'html',
timeout: 1000,
error: function(){alert('Error loading PHP document');},
success: function(result){alert(result);}
});
