我试图这样做,
$('#uploadClicked').click(function() { var table = $('#dataTable-ageGroup').DataTable(); var data = table.$('input,select').serialize(); var json = JSON.stringify(data); document.getElementById('json').setAttribute('value',json); alert("The following data would have been submitted to the server:\n\n" + data); document.getElementById('UploadDb').submit(); return false; });
但结果是一种我不明白的形式。
location=Barangay+1&ageGroup=All+Ages&bothSexes=2197&male=1086&female=1111&location=Barangay+1&ageGroup=Under+1&bothSexes=42&male=17&female=25&location=Barangay+1&ageGroup=1+-+4&bothSexes=169&male=88&....
解决方法
location=Barangay+1&ageGroup=All+Ages&bothSexes=2197&male=1086&female=1111&location=Barangay+1&ageGroup=Under+1&bothSexes=42&male=17&female=25&location=Barangay+1&ageGroup=1+-+4&bothSexes=169&male=88&....
jQuery的serialize函数采用表单元素,并从中创建一个可以发送到服务器的字符串。序列化函数仅适用于表单元素(< input>< textarea>,< select>),所以在上面的代码示例中 – 表的结果$(‘input,select’)。采取< input>和< select>元素在数据表内,并将它们序列化(使它们成为准备发送到服务器的字符串)。
使用它的一个问题是Datatables的分页不会在dom中提供所有元素,所以选择器只会得到其中的一些。
当使用分页时 – 只有正在显示的当前页面在DOM内部是“构建”,这意味着 – 如果您提交包含表的表单,则只会发送该页面内的字段。
为了发送所有数据,您将必须使用数据表的API。
要从DataTable获取所有数据,即使数据被分为页面,也可以使用data()函数:
table.DataTable().data()
该函数的结果将是您可以使用的对象,以便从datatable中的所有页面中提取所有数据。请注意,您可以使用JSON.stringify函数来获取可用于发送到服务器的json-ready字符串。
$(function() { t = $('#example').DataTable( { "pagingType": "full_numbers" }); $('#get-result').click(function() { $('#result').val(JSON.stringify(t.data())); }); });

JSON.stringify(t.data())还将为您提供有关Datatable实例的更多信息。如果你只想纯粹的数据,你可以过滤掉它:
ar = []; for (var i = 0; i < t.data().length; i++) { ar[i] = t.data()[i]; } json = JSON.stringify(ar);
However – you still have problems here if your table contains form fields,since the
data()
function will not return the value,but the<input name=X value=Y>
string.
为了改变,你将需要一个特殊的函数来获取表中的所有元素,并将它们“手动”转换:
为了获取分页数据表中的表单元素的值,您将需要使用API提取表单元素,并从中获取值。
以下是一个如何做的例子:
$(function() { t = $('#example').DataTable( { "pageLength" : 5,"pagingType": "full_numbers" }); $('#get-result').click(function() { ar = $() for (var i = 0; i < t.rows()[0].length; i++) { ar = ar.add(t.row(i).node()) } $('#result-serialized').val(ar.find('select,input,textarea').serialize()); json_obj = {} ar.find('select,textarea').each(function(i,el) { json_obj[$(el).attr('name')] = $(el).val(); }); $('#result-json').val(JSON.stringify(json_obj)); }); });

为了将值发布到服务器(例如使用jquery的ajax发布请求),您可以使用以下任一版本:
$('#submit-form-btn').click(function() { // Option 1: using the serialized version ar = $() for (var i = 0; i < t.rows()[0].length; i++) { ar = ar.add(t.row(i).node()) } $.ajax({ type: "POST",url: 'url-to-post',data: ar.find('select,textarea').serialize(),success: function() { //do something } }); // Option 2: using the object we just created: json_obj = {} ar.find('select,el) { json_obj[$(el).attr('name')] = $(el).val(); }); $.ajax({ type: "POST",data: json_obj,success: function() { //do something } }); });
