一、我们平时使用ajax向后台传递数据时，通常会传递json格式的数据，当然这里还有其它格式，比如xml、html、script、text、jsonp格式。
json类型的数据包含json对象和json类型的字符串
JSON.stringify()，将JSON对象转换为JSON类型的字符串
JSON.parse()，将JSON类型的字符串转换为JSON对象
1、直接传递json对象，示例如下：
<span style="font-size:14px;"><script>
var jsondata={"Participant":[{"Name_1":"1","Position_1":"1","Tel_1":"1","Mobile_1":"1","Ohter_1":"1"},{"Name_2":"1","Position_2":"1","Tel_2":"2","Mobile_2":"2","Ohter_2":"2"}]}
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "ApplyEdit.aspx/SaveParticipant",
data: jsondata,
dataType: "json",
complete: function () { },
success: function (result) {
},
error: function (result, status) { }
});
</script></span>
2、使用JSON.stringify()，将JSON对象转换为JSON类型的字符串示例如下：
<span style="font-size:14px;"><script>
var jsondata={"Participant":[{"Name_1":"1","Position_1":"1","Tel_1":"1","Mobile_1":"1","Ohter_1":"1"},{"Name_2":"1","Position_2":"1","Tel_2":"2","Mobile_2":"2","Ohter_2":"2"}]}
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "ApplyEdit.aspx/SaveParticipant",
data: JSON.stringify(jsondata),
dataType: "json",
complete: function () { },
success: function (result) {
},
error: function (result, status) { }
});
</script></span>
3、直接传递JSON类型的字符串，如下：
<span style="font-size:14px;"><script>
var jsondata="{\"name\":\""+name+"\",\"password\":\""+password+"\"}";
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "ApplyEdit.aspx/SaveParticipant",
data: jsondata,
dataType: "json",
complete: function () { },
success: function (result) {
},
error: function (result, status) { }
});
</script></span>
4、使用JSON.parse()，将JSON类型的字符串转换为JSON对象，示例如下：
<span style="font-size:14px;"><script>
var jsondata="{\"name\":\""+name+"\",\"password\":\""+password+"\"}";
$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "ApplyEdit.aspx/SaveParticipant",
data: JSON.parse(jsondata),
dataType: "json",
complete: function () { },
success: function (result) {
},
error: function (result, status) { }
});
</script></span>
