当字符串发布到服务器时，如何更改我不会收到错误的字符串？

Question

我有这个ajax电话：

    $.ajax( {           
      type: "POST",     
      url: "../someService",
      contentType: "application/json; charset=utf-8",
      dataType: "json", 
      data: '{ prefixText:"'+ some"text +'", count:10 }', 
      success: function( data ) {   
       response(data.d);
      },
       error: function (error) {
         alert("error")
        }
    });

执行代码时出现错误，因为我发送给webService的字符串包含双引号。

Answer 1

You're sending JSON, so you need to be sure to send valid JSON. Your string is not valid JSON for at least a couple of reasons: You don't have your property keys in quotes, and you have a syntax error because of quoting.

Don't hand-create JSON. Instead, create the object and use a serializer to create the JSON for it:

$.ajax( {           
  type: "POST",     
  url: "../someService",
  contentType: "application/json; charset=utf-8",
  dataType: "json", 
  data: JSON.stringify({ prefixText: "some" + text, count: 10 }),  // ***
  success: function( data ) {   
   response(data.d);
  },
   error: function (error) {
     alert("error")
    }
});

当您使用JSON作为数据类型时，您可以直接使用该对象，如

$.ajax( {           
  type: "POST",     
  url: "../someService",
  contentType: "application/json; charset=utf-8",
  dataType: "json", 
  data: { prefixText: "some" + text, count: 10 },  
  success: function( data ) {   
   response(data.d);
  },
   error: function (error) {
     alert("error")
    }
});
