How to refresh datatable column data - javascript

I use data table plugin with table as data source. I have to change some column value via javascript when the user types in some numbers into an input (this input is part of the table too and I have to export this values to). It is working well but when I want to export the table the columns witch was changed with javascript is not displayed in the exported file.
I think the problem is that I have not refreshed the datatable plugin. Is this correct? If yes how do I refresh the datasource? If no what can be the problem and how can I solve it?
I tried the refresh() method (var dataTableObject = $(this).parents('table').dataTable(); dataTableObject.refresh();) and the $(this).parents('table').dataTable() but is not working.
Edit: Here is how do I change the cell value:
$item.find('input.quantity-coefficient').each(function (i, d) {
$(d).off('change').on('change', function () {
var multiplier = $(this).val();
//var dataTableObject = $(this).parents('table').dataTable();
$($(this).data("row-price-info-class")).each(function (i, d) {
var priceContainer = $(d);
var price = parseFloat(priceContainer.data('price-value'));
var priceInfoRatioContainer = $(priceContainer.data("ratio-input-class"));
if (multiplier * price == 0) {
priceInfoRatioContainer.closest("td").addClass("no-euro");
priceInfoRatioContainer.html(" ");
} else {
priceInfoRatioContainer.closest("td").removeClass("no-euro");
priceInfoRatioContainer.html(localizeNumber(multiplier * price));
}
});
//TODO redrow the data
$(this).parents('table').dataTable().fnDraw();;
});
});

You can refresh the dataTable with fnDraw(). In your example:
$(this).parents('table').dataTable().fnDraw();

Thank you guys but I think I found the solution in this post: jquery DataTables - change value of a cell not just display value
When I tried it on the first time the problem was that I started the row numbering from 1 and not from 0.
So for the others who may have this issue to, I have to use something like this:
(this).parents('table').dataTable().fnUpdate("new value", 0, 2)
To update the cell value. Actually this is not what I asked because this is not refresh all the table, but this is a solution for me now.

How to determine if JQGrid has value in first load?

I found this LINK and I try the answer but it is only counting the row not the data in jqgrid.
Code
function testingforBBPDS() {
var BBPDSCount = jQuery('#BBDPSEmplList').jqGrid('getGridParam', 'reccount');
if (BBPDSCount > 0) {
$("#btnRemoveByBatchAllEmp").removeAttr("disabled");
}
}
It return 5 not 2 because I have 2 data in my jqgrid at first load.
TO all who view my post I solved it by using this var test= jQuery("#jqgrid").jqGrid('getGridParam', 'records'); and I put it inside the loadComplete function
Thanks for this LINK

easyui datagrid insertrow get input value

I mean I want to insert a new row in datagrid to use insertrow method.
but the rows parameter is fixed ,i want to get the new values when i click save button
code belows.
$("#insertRow").click(function(){
var row = $('#dg').datagrid('getSelected');
if (row){
var index = $('#dg').datagrid('getRowIndex', row);
} else {
index = 0;
}
$('#dg').datagrid('insertRow', {
index: index,
row:{long:row.long} //I mean this place must be the value i typed ,like row.long
});
$('#dg').datagrid('selectRow',index);
$('#dg').datagrid('beginEdit',index); });
you can try like this if you want to set the blank value
$('#dg').datagrid('insertRow', {
index: index,
row:{long:''}
});
and row:{long:'long1'} to set the value to the field
** if this is not helping, please provide your datagrid code and please more explicit of your code row:{long:row.long}

Dynamically added input box problem?

I have dynamically added div.In which i have text box.While adding dynamic div i can put a value to the current div but not the previously open divs. I want to ask how to add Value to the previously open text boxes of Div.
Thank You
here is a solution that refresh ALL. (I don't understand the "previously open text box" part of your question. Well I understand it, but it doesn't show in your code. I assume the "rhythm" column of your table is an input/textarea html element (since you use it's value).
Please note I'm not sure what the vitalset function is supposed to accomplish, or what "vitals_form_readings_1_rhythm" is.
function queryDb(statement)
{
dbQuery = new air.SQLStatement();
dbQuery.sqlConnection = db;
dbQuery.text = statement //"SELECT * FROM rhythm";
//alert(dbQuery.text);
try {
dbQuery.execute();
} catch (error) {
air.trace("Error retrieving notes from DB:", error);
air.trace(error.message);
return;
}
return (dbQuery.getResult());
}
function crhythm()
{
var statement = "SELECT * FROM rhythm";
return queryDb(statement)
}
function reading_speedcode()
{
if (!cvitals) {
var crhythms = crhythm();
var i=0;
$(crhythms).each( function () {
crhythm = this.crhythm;
var pr = 'card_' + i;
$('#rhythm1').append('<br/><td class="content_big" id="'+pr+'" name="'+pr+'">' + crhythm + ' </td>');
i++
});
}
});
$(document).ready( function () {
reading_speedcode();
$('#rhythm1 .content_big').live('click', function(event) {
$('#rhythm1').empty()
reading_speedcode();
});
});
now, there are several things about your code.
variable naming. (for god sake use meaningful names!)
reading full table when you need one row
where is cvitals declared or assigned?
string parsing. Jquery is good at working with set of elements, there should be no need to parse "pr" to recover the row number.
if a value is inserted in rhythm table (or deleted) before your click, the vitalset logic fails. you might want to use the table id instead.
make sure "#vitals_form_readings_1_rhythm" is unique, not retrieved from the table.
if you can answer my question from the top of this post(vitalset function, vitals_form_readings_1_rhythm, cvitals) I will try improve the code.

Can't get javascript/jquery to sort elements correctly more than one time

I have child divs that I'm trying to sort based on a jquery .data() value that I give them that is just a single number. This code works perfectly, but only once, after that I can't figure out how the heck it's sorting them. Here is a simplified version:
var myArray = $('#container div').get();
myArray.sort(function(x,y) {
return $(x).data('order') - $(y).data('order');
});
$('#container').empty().append(myArray);
I've tried so many other different methods of sorting, other plugins, etc., and I can't get anything to work right. This is as close as I can get. I just have this running on a jquery change event.
Here is the whole thing in case I'm doing something stupid elsewhere:
$('#attorneyFilter').change(function() {
//get array of links for sorting
var myArray = $('#attorneyBlocks div').get();
var selectedArea = $(this).val();
//sort alphabetically when "all" is selected
if (selectedArea == 'all') {
$('#attorneyBlocks div').show();
myArray.sort(function(a,b) {
return $(a).text() > $(b).text() ? 1 : -1;
});
//filter attorneys based on practice area and then assign its order# to the div with data, getting all values from the div's class
} else {
$('#attorneyBlocks div').hide().each(function() {
var attorneyArea = $(this).attr('class').split(', ');
for (var i=0;i<attorneyArea.length;i++) {
var practiceArea = attorneyArea[i].split('-');
if (selectedArea == practiceArea[0]) {
$(this).show().data('order',practiceArea[1]);
}
}
});
//sort based on order, the lower the number the higher it shows up
myArray.sort(function(x,y) {
return $(x).data('order') - $(y).data('order');
});
}
//append order back in
$('#attorneyBlocks').empty().append(myArray);
});
And a link to the page in question
Here's a jsFiddle with this working using .detach() instead of .empty() to keep the data.
http://jsfiddle.net/shaneblake/Tn9u8/
Thanks for the link to the site, that made it clear.
It seems to me you never clear out the data from the prior time. You hide everything but maybe something like this will solve your problem (here I set everything hidden to the bottom, you can clear it or use a different value -- as long as it is not the same as any sort key):
$('#attorneyBlocks div').hide().data('order',999999).each(function() {
var attorneyArea = $(this).attr('class').split(', ');
for (var i=0;i<attorneyArea.length;i++) {
var practiceArea = attorneyArea[i].split('-');
if (selectedArea == practiceArea[0]) {
$(this).show().data('order',practiceArea[1]);
}
}
});
Also, the code on the server is missing the 2nd line you have above:
var myArray = $('#attorneyBlocks div').get();
The problem is the change event is tied to the original items. After the sort you make all new items. They don't have any event tied to them. You will need to use .live()
Eventually figured it out, the data values from hidden divs were screwing with my sorting, so I changed my sorting code to only pay attention to :visible divs and that did the trick. Doh! Thanks for your help everyone.

How do I manipulate a jqGrid's search/filters?

I have a jqGrid with a navBar that has search: true and multipleSearch: true. I would like to add a button to my UI that automatically adds an additional rule to the search.
I've tried manipulating the postData for the filter directly, but values added this way don't show up in the search UI.
I've also tried accessing the search box directly using jQuery, like this:
$('#fbox_list').searchFilter().add();
$('#fbox_list .sf .data input').each(function(index) {
alert($(this).val());
});
But, in addition to feeling hackish, it only works if the user has already clicked on the search button (the fbox_list div is not constructed on load).
Has anyone else dealt with an issue like this?
For the sake of posterity, here is the hack I'm currently using. The grid has an ID of list and the pager has an ID of pager:
jQuery(document).ready(function() {
//Initialize grid.
//Initialize the navigation bar (#pager)
//Hack to force creation of the search grid.
//The filter's ID is of the form #fbox_<gridId>
jQuery('#pager .ui-icon-search').click();
jQuery('#fbox_list').searchFilter().close();
//Example button events for adding/clearing the filter.
jQuery("#btnAddFilter").click(function() {
//Adds a filter for the first column being equal to 'filterValue'.
var postFilters = jQuery("#list").jqGrid('getGridParam', 'postData').filters;
if (postFilters) {
$('#fbox_list').searchFilter().add();
}
var colModel = jQuery("#list").jqGrid('getGridParam', 'colModel');
//The index into the colModel array for the column we wish to filter.
var colNum = 0;
var col = colModel[colNum];
$('#fbox_list .sf .fields select').last().val(col.index).change();
$('#fbox_list .sf .data input').last().val('filterValue');
$('#fbox_list .sf .ops select.field' + colNum).last().val('eq').change();
$('#fbox_list').searchFilter().search();
});
jQuery("#btnClearFilter").click(function() {
$('#fbox_list').searchFilter().reset();
});
});
If you mean the filter toolbar, you can do this: (status is the col name -- so, replace "#gs_status" w/ "#gs_" + your_col_name
jQuery("#distributor_grid").jqGrid('showCol',['status']);
jQuery(".ui-search-toolbar #gs_status")
.val('ALL')
;
$('#distributor_grid').RefreshData(); // triggers toolbar
to clear inputs, selects and reset grid
$("td#refresh_navGrid").click();
