[英]Unable to receive JSON from JQuery ajax call
I have determined that my JSON, coming from the server, is valid (making the ajax call manually), but I would really like to use JQuery.我已经确定我的来自服务器的 JSON 是有效的(手动进行 ajax 调用),但我真的很想使用 JQuery。 I have also determined that the "post" URL, being sent to the server, is correct, using firebug.
我还使用 firebug 确定发送到服务器的“发布”URL 是正确的。 However, the error callback is still being triggered (parse error).
但是,错误回调仍然被触发(解析错误)。 I also tried datatype: text.
我也试过数据类型:文本。
Are there other options that I should include?我应该包括其他选项吗?
$(function() {
$("#submit").bind("click", function() {
$.ajax({
type: "post",
url: "http://myServer/cgi-bin/broker" ,
datatype: "json",
data: {'start' : start,'end' : end},
error: function(request,error){
alert(error);
},
success: function(request) {
alert(request.length);
}
}); // End ajax
}); // End bind
}); // End eventlistener
Here are a few suggestions I would try:以下是我会尝试的一些建议:
1) the 'datatype' option you have specified should be 'dataType' (case-sensitive I believe) 1)您指定的“数据类型”选项应该是“数据类型”(我相信区分大小写)
2) try using the 'contentType' option as so: 2) 尝试使用 'contentType' 选项,如下所示:
contentType: "application/json; charset=utf-8"
I'm not sure how much that will help as it's used in the request to your post url, not in the response.我不确定这会有多大帮助,因为它用于对您的帖子 url 的请求,而不是在响应中。 See this article for more info: http://encosia.com/2008/06/05/3-mistakes-to-avoid-when-using-jquery-with-aspnet-ajax (It's written for asp.net, but may be applicable)

3) Triple check the output of your post url and run the output through a JSON validator just to be absolutely sure it's valid and can be parsed into a JSON object. 3) 三重检查您的帖子 url 的输出并通过 JSON 验证器运行输出,以确保它是有效的并且可以解析为 JSON 对象。 http://www.jsonlint.com

Hope some of this helps!希望有些帮助!
Why myResult
instead of request
?为什么是
myResult
而不是request
?
success: function(request) {
alert(myResult.length);
}
The data parameter is wrong.数据参数错误。 Here is an example that works:
这是一个有效的示例:
data: { index: ddl.selectedIndex },数据:{索引:ddl.selectedIndex},
This contructs an object with property called index with value ddl.selectedIndex.这将构造一个名为 index 且值为 ddl.selectedIndex 的属性的对象。
You need to remove the quotes from your data parameter line您需要从数据参数行中删除引号
Good luck A祝你好运
