Question

下面,我把我的上页功能用 j。

Please tell me how to pass query string.

<script type="text/javascript" src="script/jquery-1.3.2.min.js"></script>

<script type="text/javascript">
  $(document).ready(function() {
    $( #Customers ).change(function() {
      $.ajax({
        contentType: "text/html; charset=utf-8",
        data: "CustomerID=" + $( #Customers ).val(),
        url: "FetchCustomer.aspx",
        dataType: "html",
        success: function(data) {
          $("#CustomerDetails").html(data);
        }
      });
    });
  });
</script>

我有几个问题。

when type: "POST", then contentType: "application/json; charset=utf-8", has to be application/json? it can not be html?
when type: "POST" then url can t be like url: "Customer.aspx?ID=101/FetchCustomer" I mean I can not then pass query string.

请参见《指南》。增编

Answer 1

类型

当你确定<代码>类型:“POST”时,在像<编码>的查询中,形式价值并不明显。

The HTML specifications technically define the difference between "GET" and "POST" so that


former means that form data is to be encoded (by a browser) into a URL while the latter means that 

the form data is to appear within a message body. But the specifications also give the usage 

recommendation that the "GET" method should be used when the form processing is "idempotent", and in

 those cases only. As a simplification, we might say that "GET" is basically for just getting 

(retrieving) data whereas "POST" may involve anything, like storing or updating data, or ordering a 

product, or sending E-mail.

REF:

  $(document).ready(function() {
    $( #Customers ).change(function() {
      $.ajax({
        type: POST ,
        contentType: "text/html; charset=utf-8",
        data:{CustomerID:$( #Customers ).val()},
        url: "FetchCustomer.aspx",
        dataType: "html",
        success: function(data) {
          $("#CustomerDetails").html(data);
        }
      });
    });
  });

Answer 2

您可以简单地删除内容类型,并指明某种类型。

  $.ajax({
    type:"POST",
    data: "CustomerID=" + $( #Customers ).val(),
    url: "FetchCustomer.aspx",
    success: function(data) {
        $("#CustomerDetails").html(data);
    }
  });
