I have a large table (4000 rows, 17 columns) with which I use Sorttable. It's somewhat usable in Chrome (not so much in IE). I'd like to add some checkboxes (not on each row, just in a control panel besides the table) to show/hide groups of rows, using Javascript. I'm not (so far) using JQuery or anything other than Sorttable (which works great, by the way).
What's the best way to hide those rows? I think I need to do more than just set display: none; on the rows I want to hide, as I think this means the row would still get sorted by Sorttable. I suppose I want to remove the row from the table altogether, and keep them in some list outside the DOM? Would anybody happen to have some existing/sample code that does that?
One possibility is to save all data in JSON and then write it to an table. By this you can remove the item from the table, sort the table and add the item again if you'd like.
Don't have an example right now but check it out.
Could probebly save the table with

Hope it's some help

This is a image of my sample code. I want to sort this table data, column wise when click the each sort button in top in the table. This table contains PHP also.
Number
Date
Three
Five
One
Four
Two
When user click on sort button, entire row should be sorted in acs or desc according to clicked column's data. Column contains words and column 2 contains dates.
Anyone knows that help me please....
Thanks
Can you check jquery datatable plugin. That supports sorting, expanding columns for a table. Please see the link
https://datatables.net/examples/basic_init/table_sorting.html
I would start with this:
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_sort_table
It's works just fine, and doesn't require even jQuery, let's alone jQuery plugins.
It's obviously, you should adapt code to sort with different columns names (not just for "Name"), but is easy enough.
You can use table-sorter (a client-side table sorting) and sort the table once after the page loaded. After that each of the columns is sortable by clicking the column header (It is in pure javascript and doesn't need jquery):

I have used the tablesorter jQuery plugin. It is a light weight and a very good plugin for your needs. I think this will suits to your need.
I have the buttons on both rows being added dynamically just as another <td> after each of the table data and it just gets added as something outside of the table. I'm guessing this is pretty hack-ish, and it doesn't even work for the first table. What would be the best way to achieve what I'm trying to do? These tables are just tables with table rows and table data.
Thanks!
In my application I have table that can have multiple columns, based on date range selected.
I need to be able to display table containing 20 columns or 50 columns (number of columns is based on data range from parameters). I did that, but I was refreshing page when my parameters changed.
Now I'm trying to do it better.
I've created sample that shows my approach: http://live.datatables.net/fojusec/3
Basically I'm swapping "table" with new content that comes from ajax request and then I'm calling "dataTable" on that new table.
My example works fine, but I was wondering if maybe there is a better way to do it, maybe by reconfiguring table?
Is it safe to do that like I did it? I'm worried about any leaks.
EDIT:
What I'm not sure is if dataTable object is attached to table. So if I'm removing table from DOM should I be removing dataTable object also.
I would like to avoid any conflicts. I clicked on my example for some time and I didn't got any errors.
QUESTION: What is the best way to swap or reconfigure table using datatables 1.10
Maybe this information is out there and my Google-fu is failing me, however I can't seem to find the answer. How can I get the number of rows being currently displayed in a jqGrid?
Every question and answer I've found on this topic tells you how to get either the total number of rows (displayed or not) or the number of rows loaded by an external service. Instead, I'm trying to get how many rows are being displayed in the current page of the jqGrid. One of my jqGrid attributes is rowList:[10,20,30], but I'm not sure how to access which one is selected myself.
All I want is how many rows are being currently dislpayed on each page of the jqGrid. The closest thing I've found so far has been this Q&A, but this displayed how many <tr>s there are and wasn't really what I needed.
$('.ui-pg-selbox').val()
Tested on the latest jqGrid (4.4.1)
Of course, if you have more than jqGrid per page, you can use an wrapper to ensure that it is the one you're looking for.
$('#myjqGridWrapper .ui-pg-selbox').val()
Not sure whether it's the best way, but it gets the job done.
The space means a descendant selector, that is it looks for elements containing the class ui-pg-selbox which are descendant of an wrapper #myjqGridWrapper. That would require having a div or some other wrapper around your table.
UPDATE: Also, if you have the table ID or a reference, you can use a more sturdy way of querying its jqGrid instance's .ui-pg-selbox:
$('#jqgridTableId').closest('.ui-jqgrid').find('.ui-pg-selbox').val()
The following will return you the number of displayed rows on a grid's page:
$('#myjqGridWrapper').getGridParam('reccount');
You shouldn't rely on the view for information. You should pull this information out of the JQGrid model. You can do so by calling the getGridParam method like so:
var rowNum = jqGrid.getGridParam('rowNum');

I have an HTML table (that gets its data from a database, but thats besides the point) that has a checkbox for each row. Is ther an easy way to allow the user to check the checkbox by clicking anywhere in the row, rather than the checkbox itself? I know this can be done using javascript, but is there an easy way to do it in rails? Anyone know of any gems or tutorials online?
Here's a working jsfiddle example: http://jsfiddle.net/3XZvV/2/
It uses the first checkbox in each table row. Put them in any <td>. You can show the checkboxes, but you'll need to modify it to allow them to be clicked -- this design doesn't accommodate for clickable checkboxes since it fires the event when anything in that table row is clicked. (It was good enough for this question, but we're open to improvements.)
Here's the JavaScript to accomplish this:
$('.clickable tr').click(function() {
var c = $(this).find(':checkbox').filter(':first');
c.attr('checked', !c.attr('checked'));
$(this).toggleClass('selected');
});
Just put class="clickable" on your table. In order to make it obvious that you can interact with rows, some CSS is nice. See the fiddle.
You'd have to use JavaScript. It's actually no that hard. Just add a click event for each TR that toggles the checked="checked" state of the checkbox, and changes the background color of the TR as well to show that it has been selected.
As a further enhancement, you could remove the checkbox altogether and use a hidden field instead, to save visual space. Just be sure your users are aware that the table rows are selectable.
