How to Add Export button in Jquery Custom Datatable

I am using a Web Template for my web site. I am developing with ASP.NET webform. The data will be shown in a Gridview. The Template also has a custom datatable file but without an Export button. I am sharing the js file here. Can anyone help me to edit the jquery and add the export button (PDF, Excel, and Copy)!
Thanks

where am i missing a bracket?

Pay attention to your $.getJSON functions, they are missing } for the if (data != null) and }); for the $.getJSON, so
var boxWidth = 133;
var spaceBetween = 6;

You are missing closing bracket } for if condition and closing bracket, closing parenthesis and semicolon }); for your $.getJSON function call.

In each of the first two functions there are two closing brackets missing. In such a case, use an editor like Notepad++ or an IDE which has syntax highlighting and shows you corresponding brackets when you mark one of the pair to find where one is missing. This should do it:
function addBoxToEnd() {
var lastBox = $("div.property-carousel-box:last");
var rightId = parseInt($(lastBox).attr("pageindex"), 10);
var jsonUrl = '<%= Url.Action("NextProperty", "Carousel") %>/' + rightId;
var itemLeft = (parseInt($(lastBox).css("left"), 10) * 1) + boxWidth + spaceBetween;
$("div#property-carousel-box-container").append("<div class='property-carousel-box property-carousel-box-jquery' style='left: " + itemLeft + "px;'><div class='property-carousel-box-frame'></div></div>");
$.getJSON(jsonUrl, function (data) {
if (data != null) {
var lastBox = $("div.property-carousel-box:last");
$(lastBox).css("background", "url('" + data.ImageUrl + "') no-repeat");
$("div.property-carousel-box:last > div.property-carousel-box-frame:first").append(data.Location + "<br />" + data.Rent);
$(lastBox).attr("propertyid", data.PropertyId);
$(lastBox).attr("pageindex", data.Page);
$(lastBox).click(function () {
location.href = '<%= Url.Action("Details", "Properties") %>/' + data.PropertyId;
});
}
}
}
function addBoxToStart() {
var firstBox = $("div.property-carousel-box:first");
var leftId = parseInt($(firstBox).attr("pageindex"), 10);
var jsonUrl = '<%= Url.Action("PreviousProperty", "Carousel") %>/' + leftId;
var itemLeft = (parseInt($(firstBox).css("left"), 10) * 1) - boxWidth - spaceBetween;
$("div#property-carousel-box-container").prepend("<div class='property-carousel-box property-carousel-box-jquery' style='left: " + itemLeft + "px;'><div class='property-carousel-box-frame'></div></div>");
$.getJSON(jsonUrl, function(data) {
if (data != null) {
firstBox = $("div.property-carousel-box:first");
$(firstBox).css("background", "url('" + data.ImageUrl + "') no-repeat");
$("div.property-carousel-box:first > div.property-carousel-box-frame:first").append(data.Location + "<br />" + data.Rent);
$(firstBox).attr("propertyid", data.PropertyId);
$(firstBox).attr("pageindex", data.Page);
$(firstBox).click(function() {
location.href = '<%= Url.Action("Details", "Properties") %>/' + data.PropertyId;

Triggering change events in a loop results in loss events

I am triggering a change event on a combo box for multiple values but unfortunately events are getting lost. Is there a way to wait for one event to complete before triggering the next event. Sample code is shown below
for (i = 0; i < contextFilters.length; i++)
{
var contextFilter = contextFilters[i];
if (contextFilter != "")
{
var cfData = contextFilter.split(":");
var cfName = cfData[0];
var cfVal = cfData[1];
if (cfName != null)
{
//alert("cfName : " + cfName);
//alert("cfVal : " + cfVal);
$('#context_filter').val(cfName);
$('#context_filter').trigger('change', cfVal);
}
}
}
When the event is triggered a new select box is added to the DOM but not all select boxes are getting added.
Also the change event handler is a s shown below
$('#context_filter').change(function(event, selectValues)
{
if ($(this).prop("selectedIndex") > 0)
{
populateDateValues();
var contextFilterComboObject = $(this);
var selectedVal = $(contextFilterComboObject).val();
var validate = $('#collapsiblePanel :input').attr('disabled') == null;
if (!validate)
{
$('table[id*=OtherOptions] :input').attr('disabled', false);
$('#collapsiblePanel :input').attr('disabled', false);
}
var formInput = decodeURIComponent($('#rptInputParams').serialize());
formInput += "&validate=" + validate;
$('#ajaxBusy').show();
$.getJSON('GetContextFilterData', formInput, function(data)
{
var selectBox = '<tr><td class="celltoppad"><b>' + selectedVal +
' : </b></td> <td class="celltoppad"><select multiple="multiple" name="' +
selectedVal.toLowerCase() + '" id="' + selectedVal.toLowerCase() + '" >';
var errorMsg = '';
var errorCount = 1;
errorMsg += '<html>';
$.each(data.errorMessageList, function(index, value)
{
errorMsg += errorCount + ') ' + value + '</br></br>';
errorCount++;
});
errorMsg += '</html>';
if (errorCount > 1)
{
$('#ajaxBusy').hide();
showErrorDialog(errorMsg, errorCount * 20);
$(contextFilterComboObject).prop("selectedIndex", '0');
return;
}
$.each(data.contextFilterDataList, function(index, value)
{
selectBox += '<option value="' + value + '">' + value + "</option>";
});
selectBox +=
'</select></td><td class="celltoppad"><a href="#"><img id="removeCF" ' +
'src="../images/remove.png"/></a></td></tr>';
$('#ajaxBusy').hide();
// If the context filter has not been already added.
if ($('#' + selectedVal.toLowerCase()).length == 0)
{
$('a[id*=_showDialog]').hide();
toggleDatePickerLink();
$('img#removeDate').hide();
$('table[id*=OtherOptions] :input').attr('disabled', true);
$('#collapsiblePanel :input').attr('disabled', true);
$('table#context_filter').append(selectBox);
$(contextFilterComboObject).prop("selectedIndex", '0');
}
if (selectValues != null)
{
$('#' + selectedVal.toLowerCase()).val(selectValues.split(","));
}
$('#' + selectedVal.toLowerCase()).multiselect({
noneSelectedText: 'Please select',
selectedList: 3,
selectedText: '# of # selected',
position: {
my: 'left center',
at: 'right center',
offset: '20 100'
}
}).multiselectfilter();
});
}
});

instead of triggering the event, can't you just call the handler ?
var handler = function(event, selectValues)
{
if ($('#context_filter').prop("selectedIndex") > 0)
{
populateDateValues();
var contextFilterComboObject = $('#context_filter');
var selectedVal = $(contextFilterComboObject).val();
var validate = $('#collapsiblePanel :input').attr('disabled') == null;
if (!validate)
{
$('table[id*=OtherOptions] :input').attr('disabled', false);
$('#collapsiblePanel :input').attr('disabled', false);
}
var formInput = decodeURIComponent($('#rptInputParams').serialize());
formInput += "&validate=" + validate;
$('#ajaxBusy').show();
$.getJSON('GetContextFilterData', formInput, function(data)
{
var selectBox = '<tr><td class="celltoppad"><b>' + selectedVal +
' : </b></td> <td class="celltoppad"><select multiple="multiple" name="' +
selectedVal.toLowerCase() + '" id="' + selectedVal.toLowerCase() + '" >';
var errorMsg = '';
var errorCount = 1;
errorMsg += '<html>';
$.each(data.errorMessageList, function(index, value)
{
errorMsg += errorCount + ') ' + value + '</br></br>';
errorCount++;
});
errorMsg += '</html>';
if (errorCount > 1)
{
$('#ajaxBusy').hide();
showErrorDialog(errorMsg, errorCount * 20);
$(contextFilterComboObject).prop("selectedIndex", '0');
return;
}
$.each(data.contextFilterDataList, function(index, value)
{
selectBox += '<option value="' + value + '">' + value + "</option>";
});
selectBox +=
'</select></td><td class="celltoppad"><a href="#"><img id="removeCF" ' +
'src="../images/remove.png"/></a></td></tr>';
$('#ajaxBusy').hide();
// If the context filter has not been already added.
if ($('#' + selectedVal.toLowerCase()).length == 0)
{
$('a[id*=_showDialog]').hide();
toggleDatePickerLink();
$('img#removeDate').hide();
$('table[id*=OtherOptions] :input').attr('disabled', true);
$('#collapsiblePanel :input').attr('disabled', true);
$('table#context_filter').append(selectBox);
$(contextFilterComboObject).prop("selectedIndex", '0');
}
if (selectValues != null)
{
$('#' + selectedVal.toLowerCase()).val(selectValues.split(","));
}
$('#' + selectedVal.toLowerCase()).multiselect({
noneSelectedText: 'Please select',
selectedList: 3,
selectedText: '# of # selected',
position: {
my: 'left center',
at: 'right center',
offset: '20 100'
}
}).multiselectfilter();
});
}
});
for (i = 0; i < contextFilters.length; i++)
{
var contextFilter = contextFilters[i];
if (contextFilter != "")
{
var cfData = contextFilter.split(":");
var cfName = cfData[0];
var cfVal = cfData[1];
if (cfName != null)
{
//alert("cfName : " + cfName);
//alert("cfVal : " + cfVal);
$('#context_filter').val(cfName);
handler(null, cfVal);
}
}
}
I never tested above code, but I declared your handler as a function and then in the loop at the bottom, you can see how I call it instead of triggering it (handler(cfVal))

I was able to figure out the solution to my problem, when the back button is clicked and the change event is fired then I made the ajax call using async as false and that resolved the issue. This is because if the async is true json calls happen simultaneously and some events are lost during that period.
Thanks

JQuery easySlider not working in Chrome/Safari

Any feedback on this would be great.
I have installed the latest version of easySlider along with the latest version of JQuery but I am unable to get the images to slide in Chrome or Safari.
The initial image loads but no automatic sliding and the buttons don't work on click.
I have included the code for the page and the easySlider js code.
Thanks in advance,

In your html you have some errors (can see these in view source so not a javascript issue)
Change
<div id="slider" align="center" margin-left:10px;>
to
<div id="slider">
The align attribute is what is actually causing the issue.
Tested on Chrome (PC) v18
Hope that helps :)

Slider refuses to center photos, forces left justified

This is a really great slider but it has just one annoying fault. If I have different widths of images, the ones that are too small for the default width, are left justified. I've tried every which way to do it with the html/css but it's somewhere in the js I think. I even loaded the js after the images load and it still put it left justified even though they were centered for that split second before the js loaded. What seems to happen is, the js takes the smaller width image and makes it the full default width and adds whitespace to the right of it, essentially making it a full width image. I am just curious if this is customizable so that the photo is centered and whitespace is added on either side.
Any thoughts are appreciated, thanks for taking a look.

It seems to be taking the image source url and putting it into the background of the slider. I would first try changing
'background-position': 'top left'
to:
'background-position': 'center center'
... actually, the entire script seems geared towards tiling the images. I'd imagine that's the technique it uses to generate some of its cool effects. This line is where it's centering the current image within the tile defined by sph and spw.
'background-position': -sLeft + 'px ' + (-sTop + 'px'),
and if you use spw=1 and sph=1 you can center it by changing that to a fixed 'center center'.
I don't really care for this script in terms of general purpose, but it seems to have worked well for the person who wrote it.

this is my hacky solution
<script>
$(window).load(function() {
$('#coin-slider').coinslider({
opacity: 0.6,
effect: "rain",
hoverPause: true,
dely: 3000
});
// center coin slider
setTimeout(function(){
centerCS();
},500);
});
// center coin slider image
function centerCS(){
var w=$(".container").width(); // container of coin slider
var csw=$("#coin-slider").width();
var lpad=(w-csw)/2;
$("#coin-slider").css("margin-left",lpad+"px");
}
</script>
