jQuery UI dialog and Ajax POST in asp.net
在下面的示例中，如何在asp.net中单击登录按钮后将数据发布到webservice？
$(document).ready(function () {
var username=$("#username").val();
var password=$("#pass").val();
$("#dialog").dialog({
bgiframe: true,
autoOpen: false,
height: 400,
width: 300,
modal: true,
buttons: {
"Cancel": function () {
$(this).dialog("close");
},
"Login":function() {
$.ajax(
{
type:"POST",
dataType:"json",
url:"WebService.asmx/Login",
contentType:"application/json",
data:"{username:'"+username+"',password:'"+password+"'}",
success:function(val)
{
$("#isValid").attr("value",val.d);
}}
);
},
},
});
var isValid = $("#isValid").val();
if (isValid== "false") {
// Display the modal dialog.
$("#dialog").dialog("open");
}
});
If you have the following signature on your WebService...
function bool Login(string userName, string password)
You just need to provide a javascript object in the JSON-notation that looks like this:
{ "userName" : "Admin", "password": "1234" }
Hint: make sure that the names in the javascript object do have the same name and casing... Makes life much easier.
Hope I understood your question correctly...
