| 标题 | jQuery中通过ajax调用webservice传递数组参数的问题实例详解 |
| 范文 | 本文通过实例给大家详细介绍jQuery中通过ajax调用webservice传递数组参数的相关资料,需要的朋友可以参考下 下面通过实例给大家说明比较直观些，更方便大家了解。 本人的项目中通过jquery.ajax调用webservice. 客户端代码如下: $.ajax({ url: "test/xxx.asmx", type: 'POST', dataType: 'xml', timeout: , data: { name: "zhangsan", tags: ["aa", "bb", "cc"] }, error: function(xml) { alert(xml.responseText); }, success: function(xml) { alert("OK"); } }); 服务端代码如下: [WebMethod] public XmlDocument xxx(string name, string [] tags ) { return sth; } 总是抛出异常. 问题出现在这里: 下面是HTTP数据: POST http://xxx.com/xxx.asmx/xxx HTTP/1.1 Host: center.cmis.htpc.com.cn Connection: keep-alive Content-Length: 55 Cache-Control: max-age=0 Origin: http://xxx.com User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.186 Safari/535.1 Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Accept: application/xml, text/xml, */*; q=0.01 Referer: http://xxx.com/xxx.aspx Accept-Encoding: gzip,deflate,sdch Accept-Language: zh-CN,zh;q=0.8 Accept-Charset: GBK,utf-8;q=0.7,*;q=0.3 name=zhangsan&tags%5B%5D=aa&tags%5B%5D=bb&tags%5B%5D=cc 而它期望的格式是如下的: POST /xxx.asmx/xxx HTTP/1.1 Host: xxx.com Content-Type: application/x-www-form-urlencoded Content-Length: length name=string&tags=string&tags=string 比较上面粗体,post的数据除了问题. 正确的应该如下: name=zhangsan&tags=aa&tags=bb&tags=cc 看来问题出在jquery.ajax上面了.见代码(jquery.1.8.3.js) function buildParams(prefix, obj, traditional, add) { var name; if (jQuery.isArray(obj)) { // Serialize array item. jQuery.each(obj, function(i, v) { if (traditional || rbracket.test(prefix)) { // Treat each array item as a scalar. add(prefix, v); } else { // If array item is non-scalar (array or object), encode its // numeric index to resolve deserialization ambiguity issues. // Note that rack (as of ..) can't currently deserialize // nested arrays properly, and attempting to do so may cause // a server error. Possible fixes are to modify rack's // deserialization algorithm or to provide an option or flag // to force array serialization to be shallow. //ytx buildParams(prefix, v, traditional, add); //buildParams(prefix + "[" + (typeof v === "object" ? i : "") + "]", v, traditional, add); } }); } else if (!traditional && jQuery.type(obj) === "object") { // Serialize object item. for (name in obj) { buildParams(prefix + "[" + name + "]", obj[name], traditional, add); } } else { // Serialize scalar item. add(prefix, obj); } } 结论: 出问题的代码在22行,我修改成21行那样就行了. 不过,我对js/jquery都是一知半解的,希望不要引起别的后遗症,呵呵. 以上所述是小编给大家介绍的jQuery中通过ajax调用webservice传递数组参数的问题实例详解的相关知识，希望对大家有所帮助 |
