说明: 1、js根据表单元素class属性,把表单元素的name和value组合为json格式;用表单元素class属性可以针对性地组合JSON数据。
2、后端ASP.NET用JavaScriptSerializer反序列化为对象实列。
3、好处:简化了前端数据读取与后端数据赋值。
function GetJSONStr(class_name) {
var a = [];
//文本框
$("." + class_name).filter(":text").each(function(i) {
//alert(this.name);
//alert(this.value);
a.push({ name: this.name, value: this.value });
});
//下拉列表
$("." + class_name).filter("select").each(function(i) {
//alert(this.name);
//alert(this.value);
a.push({ name: this.name, value: this.value });
});
//单选框
$("." + class_name).filter(":radio").filter(":checked").each(function(i) {
//alert(this.name);
//alert(this.value);
a.push({ name: this.name, value: this.value });
});
//复选框开始
var temp_cb = "";
$("." + class_name).filter(":checkbox").filter(":checked").each(function(i) {
if (temp_cb.indexOf(this.name) == -1) {
temp_cb += this.name + ",";
}
});
var temp_cb_arr = temp_cb.split(",");
var cb_name = "";
var cb_value = "";
for (var temp_cb_i = 0; temp_cb_i cb_name = temp_cb_arr[temp_cb_i];
var cb_value_length = $("input[name='" + temp_cb_arr[temp_cb_i] + "']:checked").length;
$("input[name='" + temp_cb_arr[temp_cb_i] + "']:checked").each(function(i) {
if (i == cb_value_length - 1)
cb_value += this.value;
else
cb_value += this.value + ",";
});
//alert(cb_name);
//alert(cb_value);
a.push({ name: cb_name, value: cb_value });
}
//复选框结束
//组合为JSON
var temp_json = "";
for (var json_i = 0; json_i if (json_i != a.length - 1) {
temp_json += '"' + a[json_i].name + '":"' + a[json_i].value + '",';
}
else {
temp_json += '"' + a[json_i].name + '":"' + a[json_i].value + '"';
}
}
return "{" + temp_json + "}";
}
ASP.NET
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
JavaScriptSerializer Serializer = new JavaScriptSerializer();
string r = Request.Form["msg"];
//{"Name":"MyName1","Single":"one"}
t_json t_json_object = Serializer.Deserialize(r);
Response.Write(t_json_object.Name);
Response.End();
}
}
class t_json
{
public DateTime Name;
public string Single;
}
