标签: javascript ajax jsp internet-explorer-8

我使用这个ajax调用populatig值它在所有其他浏览器中工作正常但在iE 8中没有

  function makedate() {
             var value1="";
             var value2=""; 
             var value3="";
              var xmlHttpRequest = getXMLHttpRequest();

              xmlHttpRequest.onreadystatechange = makedateStateHandler(xmlHttpRequest);

              $("#button").attr("disabled", "disabled"); 
             var  date= document.getElementById("date").value;
             var  value=document.getElementById("value").value;
            // alert(value);
             var Appointmentdateformat= document.getElementById("Appointment").options[document.getElementById("Appointment").selectedIndex].value;
             //alert(Appointmentdateformat);
             var  Location = document.getElementById("Location").options[document.getElementById("Location").selectedIndex].value;
             var  Provider = document.getElementById("Provider").options[document.getElementById("Provider").selectedIndex].value;
             // alert(date+Location+Provider+Appointmentdateformat+value)  ;    
        //& Location="+Location+"&Provider="+Provider
              xmlHttpRequest.open("POST", "ajaXForgetdatesForAppoinment.jsp?date="+date+"&Location="+Location+"&Provider="+Provider+"&Appointmentdateformat="+Appointmentdateformat+"&value="+value, true);
              xmlHttpRequest.setRequestHeader("Content-Type",
                  "application/x-www-form-urlencoded");
              xmlHttpRequest.send(null);
            }
            function makedateStateHandler(xmlHttpRequest) {

                  // an anonymous function returned
                  // it listens to the XMLHttpRequest instance
                  return function() {
                    if (xmlHttpRequest.readyState == 4) {
                      if (xmlHttpRequest.status == 200) {
                          //document.getElementById('loading').style.visibility = 'hidden'; 
                         // $("#select").removeAttr("disabled"); 
                          //alert(xmlHttpRequest.responseText);
                          $("#button").removeAttr("disabled"); 
                        document.getElementById("divId").innerHTML = xmlHttpRequest.responseText;
                      } else {
                       // alert("HTTP error " + xmlHttpRequest.status + ": " + xmlHttpRequest.statusText);
                      }
                    }
                  }
                }

这是我调用此Ajax函数的JSP页面

有人可以帮我解决这个问题吗?

答案 0 :(得分:2)

甚至不要尝试调试那些makedate()makedateStateHandler()函数。他们太乱了。如果你写了那段代码,对不起那些苛刻的话。如果其他人写了它,那就开始吧! : - )

由于您已经在使用jQuery,我们使用

function makedate() {
    $('#button').attr( 'disabled', 'disabled' );
    $.ajax({
        type: 'POST',
        url: 'ajaXForgetdatesForAppoinment.jsp',
        data: {
            date: $('#date').val(),
            Location: $('#Location').val(),
            Provider: $('#Provider').val(),
            Appointmentdateformat: $('#Appointment').val(),
            value: $('#value').val()
        },
        dataType: 'text',
        success: function( data ) {
            $('#button').removeAttr( 'disabled' );
            $('#divId').html(data );
        },
        error: function( jqXHR, textStatus, errorThrown ) {
            // ...
        }
    });
}

这个简单的代码取代了那些复杂的功能。它应该是一个简单的替代品,一个主要的区别是它以POST通知的方式发送POST主体而不是URL的POST数据参数。但是,大多数服务器代码都应接受任一格式的数据。

jQuery以多种方式使这段代码更简单:

  • 内置$.ajax()代替复杂的XMLHttpRequest代码。
  • .val()获取<select> / <option>值。
  • $('#foo')代替document.getElementById()

还有一个非常重要的美容点:正确的缩进!原始代码中的缩进遍布各处。正确的缩进对于代码可读性非常重要。

在第二次查看代码后,您可能会更进一步。由于您通过POST发送的数据值来自#reg表单,因此您可以通过简单的.serialize()调用来获取所有这些值:

function makedate() {
    $('#button').attr( 'disabled', 'disabled' );
    $.ajax({
        type: 'POST',
        url: 'ajaXForgetdatesForAppoinment.jsp',
        data: $('#reg').serialize(),
        dataType: 'text',
        success: function( data ) {
            $('#button').removeAttr( 'disabled' );
            $('#divId').html( data );
        },
        error: function( jqXHR, textStatus, errorThrown ) {
            // ...
        }
    });
}

如果您的服务器代码需要,也可以轻松将数据参数移动到URL中:

function makedate() {
    $('#button').attr( 'disabled', 'disabled' );
    $.ajax({
        type: 'POST',
        url: 'ajaXForgetdatesForAppoinment.jsp?' +
             $('#reg').serialize(),
        dataType: 'text',
        success: function( data ) {
            $('#button').removeAttr( 'disabled' );
            $('#divId').html( data );
        },
        error: function( jqXHR, textStatus, errorThrown ) {
            // ...
        }
    });
}

公平警告:当然这是所有未经测试的代码!但它应该给你一个好的起点。
