我有这个从服务器接收的表: (用ajax):
$.each(data, function(i, item) {
$('#MyTable tbody').append("<tr>"d
+"<td>" +data[i].A+ "</td><td>"
+data[i].B
+"</td><td><input type='text' value='"
+data[i].C+"'/></td><td><input type='text' value='"
+ data[i].D+"'/></td>"
+ "</tr>");
});
C和D是编辑文本,用户可以更改。在用户更改之后,我想从表中“获取”所有新数据,并通过带有JSON的ajax发送它。 如何将数据读取为JSON?
我开始写一个,但我坚持:
function saveNewData(){
var newData= ...
$.ajax({
type: "GET",
url: "save",
dataType: "json",
data: {
newData: newData},
contentType : "application/json; charset=utf-8",
success : function(data) {
...
},
error : function(jqXHR, textStatus, errorThrown) {
location.reload(true);
}
});
}
谢谢

尝试这样的事情,
function getUserData()
{
var newData = new Array();
$.each($('#MyTable tbody tr'),function(key,val){
var inputF = $(this).find("input[type=text]");
var fileldValues = {};
fileldValues['c'] = $(inputF[0]).val();
fileldValues['d'] = $(inputF[1]).val();
//if you want to add A and B, then add followings as well
fileldValues['a'] = $($(this).children()[0]).text();
fileldValues['b'] = $($(this).children()[1]).text();
newData.push(fileldValues);
});
return JSON.stringify(newData);
}
function saveNewData(){
var newData = getUserData();
$.ajax({
type: "GET",
url: "save",
dataType: "json",
data: {
newData: newData},
contentType : "application/json; charset=utf-8",
success : function(data) {
...
},
error : function(jqXHR, textStatus, errorThrown) {
location.reload(true);
}
});
}

基于尼山回答的小型演示:
var newData = new Array();
$.each($('#MyTable tbody tr'), function (key, val) {
var inputF = $(this).find("input[type=text]");
var fileldValues = {};
fileldValues['c'] = $(inputF[0]).val();
fileldValues['d'] = $(inputF[1]).val();
newData.push(fileldValues);
});
alert(JSON.stringify(newData));

使用jquery on
事件绑定
尝试这样的事情。 Fiddler Demo
$('#MyTable').on('keyup', 'tr', function(){
var $this = $(this);
var dataA = $this.find('td:nth-child(1)').text() // to get the value of A
var dataB = $this.find('td:nth-child(2)').text() // to get the value of B
var dataC = $this.find('td:nth-child(3)').find('input').val() // to get the value of C
var dataD = $this.find('td:nth-child(4)').find('input').val() // to get the Valur of D
// $.ajax POST to the server form here
// this way you only posting one row to the server at the time
});
我没有做到这一点我会使用数据绑定libarray,例如Knockoutjs
或AngularJS
