如何用jquery打背方法取代以下的麻风机?

function PostCall() {
  $( #txtRes ).val( Please Wait...... );
  var reqval = $( #txtReq ).val();
  $.ajax({
    url: "myPage",
    type:  post ,
    data: "{ name : " + reqval + " }",
    async: true,
    contentType: "application/json",
    success: function (result) {
      $( #txtRes ).val(result);
    }
  });
}

Answer 1

仅对您的雅氏语句结尾处的成功表示(例如:

}.success(function(){
})

Answer 2

If you want to stick with Ajax go the jQuery 1.8 way and try this:

function PostCall() {
    $( #txtRes ).val( Please Wait...... );
    var reqval = $( #txtReq ).val();
    $.ajax({
        url:  myPage ,
        type:  post ,
        data: "{ name : " + reqval + " }",
        dataType:  json ,
        async: true,
        contentType: "application/json",
    })
    .done(function(result) {
        $( #txtRes ).val(result);
    })
    .fail(function(jqXhr, textStatus) {
        console.log( Error: ...  + textStatus);
    })
    .always(function() {
    });
}

<代码>.done()功能取代<>success。

If Ajax is not an option for you check out:

WebSockets
Http POST Requests (requires the whole page to be reloaded)
