【问题描述】:
我正在尝试对 javascript 对象进行字符串化,然后将字符串作为参数传递给 Code Behind 中的 WebMethod。我无法让它工作,因为我得到 500 的内部服务器错误,并且堆栈跟踪说参数缺少值。
这里是javascript代码:
var jSon = JSON.stringify(javascriptObject);
// "{"Foretagsnamn":"Avector","BGFarg":"000000","TextColor":"fafafa","FooterFarg":"ffffff","FooterColor":"000000","FooterLinkColor":"050505","FeaturedBorderColor":"","HoverFarg":"12ebeb","RutFarg":"0d0d0d","SelectedRutFarg":"","RutColor":"FFFFFF","LankColor":"","DelaMedSig":"1","PersonalSida":"0","StartpageTitle":"","StartpageDescription":"","GoogleMaps":"<iframe width=\"425\" height=\"350\" frameborder=\"0\" scrolling=\"no\" marginheight=\"0\" marginwidth=\"0\" src=\"https://maps.google.se/maps?f=q&source=embed&hl=sv&geocode=&q=Avector AB&aq=&sll=56.225986,12.870827&sspn=0.076248,0.154324&ie=UTF8&hq=Avector AB&hnear=&t=m&cid=645910733081021950&iwloc=A&ll=56.224594,12.859229&spn=0,0&output=embed\"></iframe><br /><small><a href=\"https://maps.google.se/maps?f=q&source=embed&hl=sv&geocode=&q=Avector AB&aq=&sll=56.225986,12.870827&sspn=0.076248,0.154324&ie=UTF8&hq=Avector AB&hnear=&t=m&cid=645910733081021950&iwloc=A&ll=56.224594,12.859229&spn=0,0\" style=\"text-align:left\">Visa större karta</a></small>","HittaKartaUrl":"http://www.hitta.se/avector ab/ängelholm/hxTP-4v1HG?vad=Avector AB","EniroKartaUrl":"http://kartor.eniro.se/m/aKkhi","Ikoner":"2","Email":"info@avector.com","AdressSida":"1","shadowColor":"ffffff","lineColor":"2b292b","MenuHoverIcon":"Välj bild från server","fontFamily":"Verdana","supportText":"Support Avector","captcha":true,"metaKeywords":"","ShowSupportInFooter":true}"
$.ajax({
type: "POST",
url: "Post/Installningar.aspx/Updatera",
data: jSon,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
var resultAsString = result.d;
//_this.parent().siblings('.SavedStatus').html(resultAsString);
if (resultAsString == "1") { // Gick bra att spara.
alert("Uppgifterna är sparade.");
document.location = document.location;
}
else {
$('#StatusText').html("Gick inte att spara uppgifterna.");
}
},
error: function (xhr, ajaxOptions, thrownError) {
}
});
这里是网络方法:
[WebMethod]
public static string Updatera(string jSon)
{
感觉就像我已经尝试了通过谷歌搜索时找到的所有东西。
我也试过这个很多人参考的指南:http://encosia.com/using-jquery-to-directly-call-aspnet-ajax-page-methods/
有什么想法吗?
【问题讨论】:
-
根据
javascriptObject的内容,您可能需要对它进行不同的序列化。尝试在$.ajax调用中设置traditional: true和data: javascriptObject。 -
尝试用
data: {"jSon":JSon},替换data: jSon, -
@jonamreddy 我已将数据:jSon 更改为数据:{“jSon”:jSon },我仍然收到错误,现在说“无效的 json 原语”。
-
你能分享一下json的价值吗?
-
@jonamreddy 我已经用 jSon 值更新了 OP。
