Ajax中参数带有html格式的 传入后台保存

Posted 2020-08-20

因业务需求  要讲如下编辑器中带有样式的数据传入数据库保存

第一种方法  json格式传入

 1   $(".privilegezn_page .btn_ok").click(function () {
 2         if (editor.html() == "")
 3         {
 4            alert("优惠使用指南内容不能为空")
 5         } else {
 6             var str = HTMLEncode(editor.html());
 7             console.log(str);
 8                 if (($("select")).length > 0) {
 9                     var hotelid = $("#hotel option:selected").attr("value");
10                 } else {
11                     var hotelid = $("#hotelid").val();
12                 }
13                 var cz = $("#xg").val();//操作名id
14                 var gnbh = $("#gnbh").val();
15                 var obj = new Object();
16                 obj.text = str;
17                 obj.xgid = hotelid;

1 function HTMLEncode(text){ 
2 text = text.replace(/&/g, "&") ; 
3 text = text.replace(/</g, "\'<\'") ; 
4 text = text.replace(/>/g, "\'>\'") ; 
5 return text; 
6 }

 

18                 obj.gnbh = gnbh;
19                 obj.cz = cz;
20                 console.log(JSON.stringify(obj));
21                 $.ajax({

23                     url: "/Business/yhsyznxg",
24                     data:{json:JSON.stringify(obj)},
25                     success: function (data) {
26                         var f = $.parseJSON(data);
27                         if (f.yz1) {
28                             alert("添加成功!");
29                             if ($("#yhsyzncx").length > 0) {
30                                 $("#yhsyzncx").trigger("click");
31                             } else {
32                                 location.replace(location.href);
33                             }
34                         }
35                         else if (f.yz1 == false) {
36                             alert("添加失败!");
37                             location.replace(location.href);
38                         }
39                         if (f.yz2) {
40                             alert("修改成功!");
41                             if ($("#yhsyzncx").length > 0) {
42                                 $("#yhsyzncx").trigger("click");
43                             } else {
44                                 location.replace(location.href);
45                             }
46                         }
47                         else if (f.yz2 == false) {

49                             location.replace(location.href);
50                         }
51                     }
52                 });
53            }   
54     })
