问题
Trying to download Datatables, able to get 0 or 1 values for checkboxes (for one of the column fields "Verified") initially, but when I am toggling the checkbox and exporting as excel, unable to retrieve the latest check box values. Initially I only had the second checkbox as not ticked in the database so its correctly exporting its values as 0 in the excel sheet but when I change the values and export it again its not taking the updated latest values as you can see in the snapshot attached as well.
var j=0;
$(document).ready(function(){
var table;
function Xhr(id)
{
return $.ajax(
{type:"GET",
url:'http://localhost:8080/SSRSReports/v1/test',
dataType:'json',
cache:false,
async:true,
beforeSend:
function(){$(id).append('<img src="images/spinner.gif" class="spin"/>');
}})
.always(function(){
$(id).find('.spin').fadeOut(4000,function(){$(this).remove();
});
})
.fail(function()
{console.log("There was a problem while trying to get data at "+d);});
}
var radio=[];
var j=0;
$(document).ready(function(){
Xhr('#report').done(function (json) {
console.log(json);
var x;
jQuery_2_2_2.each(json, function (i, report) {
radio.fill(0);
if(report.testSampleOutOfStabilityIndt==1)
{

//console.log(i);

回答1:
Tried again and basically changed the format when exporting. Also changed the check box data to be manually changed.
$(document).ready(function() {
$('.checkbox').click(function() {
debugger
if ($(this).data("checked") === 0) {
$(this).data("checked", "1")
} else {
$(this).data("checked", "0")
}
});
$('#example').DataTable({
dom: 'Bfrtip',
buttons: [{
extend: 'copyHtml5',
exportOptions: {
orthogonal: 'export'
}
},
{
extend: 'excelHtml5',
exportOptions: {
orthogonal: 'export',
format: {
body: function(data, row, column, node) {
// Strip $ from salary column to make it numeric
debugger;
if (column === 0) {
data = $(node).children().data("checked");
}
return data;
}
}
}
},
{
extend: 'pdfHtml5',
exportOptions: {
orthogonal: 'export'
}
}
]
});
});
Heres is the fiddle for the same https://jsfiddle.net/raheelshah31/fm6a74yu/2/
