ajax提交服务器数据, 整理一下转换方法。
HTML:
1.表单元素转QueryString
var q = $('#fm,#UserId').serialize(); //q = UserName=UserName1&UserId=UserId1
2.字符串, JSON 互相转换
var obj = jQuery.parseJSON('{"name":"John"}');alert( obj.name === "John" );
可以利用jquery-json插件实现转换,直接引用示例
var thing = {plugin: 'jquery-json', version: 2.3};var encoded = $.toJSON( thing );// '{"plugin":"jquery-json","version":2.3}'var name = $.evalJSON( encoded ).plugin;// "jquery-json"var version = $.evalJSON(encoded).version;// 2.3
3.表单,元素转Name,Value数组
var arr = $("#fm,#UserId").serializeArray();/*[ {name: 'UserName', value: '"UserName"1'}, {name: 'UserId', value: 'UserId'} ] */
4. 表单元素转JSON
$.fn.serializeObject = function(){ var o = {}; var a = this.serializeArray(); $.each(a, function() { if (o[this.name] !== undefined) { if (!o[this.name].push) { o[this.name] = [o[this.name]]; } o[this.name].push(this.value || ''); } else { o[this.name] = this.value || ''; } }); return o;};var obj = $('form').serializeObject();/*obj: ObjectUserId: "UserId1"UserName: "UserName1"__proto__: Object*/
5. JSON2FORM
$.getJSON('url_to_file', function(data) { for (var i in data) { $('input[name="'+i+'"]').val(data[i]); }}
Google过程中发现一个更强大的插件
data = { "Name":"Emkay Entertainments", "Address":"Nobel House, Regent Centre", "Contact":"Phone" } $('div#data').loadJSON(data);Emkay Entertainments
Nobel House, Regent Centre Phone
live demo :
ajax提交参数是,要注意提交参数的类型。如easyui grid 参数只能用JSON,不支持QueryString
