I've been looking in to a few grids that are currently built that I could just make use of however none that I have found so far provide the same functionality as an SPGridView in terms of filtering.
The closest I've managed to find is JSGrid which allows you to search each individual column.
What I'd like to do is to display all unique values for a specific column in the filtering option below the normal Ascending and descending much like the list view functionality you currently get in a document library or list.
Many Thanks

Situation:
I'm playing a little by using the Matt Kruse's library I found at the page Table Sorting, Filtering, Etc at the URL http://javascripttoolbox.com/lib/table/source.php.
It works pretty well but I wish to implement a little improvement (maybe it would be better to use the locution "new feature") and I don't know where to start because I'm a newbie in js and that js file uses more advanced programming statements I don't fully understand, not yet at least.
I have a single html file with some tables in it. Some of them are filterable and sortable thanks to that library. The number of tables may vary, the number of columns (fields) in each table may vary as well, and the number of records (rows) of each table may vary as well too. Of course the content is different in each table too.
By placing a specific css class in the th element of the targeted column I choose, I indicate to the Matt Kruse's library to create in that column a html element that is populated of a list of html elements that are computed dynamically by the js it self by picking a distinct and sole value of each record for that column.
When I wish to apply a filter to the table on the basis of certain column, I have just to choose the relative from the corresponding box and the table gets filtered accordingly, as I expect to. It works just hiding the records (the html rows) with not matching criteria in that specific column with a filter applied on it. Of course it is possible to use filters on more than one column at once if needed. It works pretty similarly to MS Excel.
The problem
When I apply a filter to a column the other columns filter drop-down combo boxes (the html elements that contain the compiled options for filtering other columns) continue to show all options instead of hiding those that are filtered in the table and are no more needed. So it becomes pretty tricky especially on complex tables to choose filtering criteria from other columns because the user has to understand by himself what are the criteria that aren't usable because the corresponding rows are already hidden by a filter already applied to another column.
One more thing: when I edit the content of one or more table cells, the filter of the relative column(s) doesn't update to match the editing made, but it seems to be to stay static.
Goal of this question
If I use a spreadsheet (as LibreOffice Calc, or MS Excel, or Google online spreadsheet, or else) when I filter a column other columns' filter drop down menu are filtered as well. If I remove a filter somewhere, other columns filters drop down are updated accordingly.
All this behavior is what I would like to implement into Matt Kruse's library. In this way it would be easier to filter by multiple columns because the boxes containing the filter criteria of the other columns will show just the filter criteria left by the all the previously applied filters.
What I have already tried
I tried to implement something to do that but it was so slow that I was too much ashamed of its execution time that I already deleted the whole algorithm I created.
For comparison using the Matt Kruse's library algorithm implies just few instants to compile all tables data into filter elements (on all tables as well). But the algorithm I've implemented needed more than 30-40 seconds for just one table. Way too inefficient.
Substantially I wrote few "for loops" that for each into each of the filtered table, compares the value of the option with each one of the corresponding column and if finds a mach keeps the option visible, else it hides that element into the . I attached that algorithm to the change event of each , so when I clicked and selected the the event was triggered and all the content of the table was updated. It worked as expected but, as I said, what I implemented was way slower.
So the question is:
How do I modify the Matt Kruse's js file to implement the feature I want keeping the highest possible performance?
(If Matt Kruse is reading this, feel free to pick up this idea and implement the new features needed above: I'm sure it would be greatly appreciated).
Thanks everybody in advance for the contribution.
I have a table with many entries (4000 - 5000) with 5 columns. These are paginated and only about 20 rows are shown at a time although all data exists at the client side.
I want the user to filter different column by categories (and if possible using some wildcards), this user input will be taken using something like Form input. Note that i can perform all the operations using Javascript code, however i am unable to understand what kind of UI elements do i need to use for this purpose (I am not from a web dev. background but learning the tricks). I tried using libraries such as selectize, researched some Jquery UI plugins. In fact i also found a spreadsheet specific library (slickgrid.js) but it is slightly beyond my skill to implement.
So in essence is there a simple way to get user input to select categories in a column(s) with all data in client array ? I would love to reach a stage where i may be able to group column categories and use them to give autocomplete/ dropdown menus etc. However i am just trying to figure out a reliable way to translate user input to string to be used in code.
I am looking for a way to sort columns programmatically.
Please bare in mind, I do not mean to sort the grid as you normally would with sortGrid() or whatnot. I mean to arrange the row order from left to right programmatically, after the grid has been rendered.
So, I am aware that with:
$("#myGrid").jqGrid({sortable: true});
I am able to sort the columns by dragging and dropping them in order. The idea is to allow users to sort their column, and to have a callback save the order in the database, so each user can arrange their own columns however they want.
I am doing something similar with showing and hiding columns, but have been unable to reorder the columns programmatically without actually dragging and dropping them.
Any help would be highly appreciated.
You can use remapColumns method to reorder the column programmatically without usage drag & drop.
In the answer you will find the code which shows how to save user specific choice of the column order in localStorage. I personally prefer the way as the saving of the same information on the server side in the database. Nevertheless you can implement saving of the same information in the database instead of localStorage. To do this you need just change the implementation of saveObjectInLocalStorage and getObjectFromLocalStorage functions and include the ajax call instead of usage window.localStorage.
I am trying to implement one sorting functionality in my code in php. The functionality will be like, when we click on the header of a column then that particular column's record will be sorted by ascending order and again click on the same column means the column's record will be sorted by descending order.
Please help me how to proceed with some example.
JQuery has many plugins that do this sort of thing. I have used Tablesorter with great results in my own projects.
I too recommend jQuery Tablesorter, it's an excellent little plugin.
You really want to avoid doing the sorting backend, as this will put strain on your server, but if you wanted to it would be as simple as appending an ORDER BY instruction to your query depending on what column the user clicked. Again, I do not recomment this method, I think you should do it in the frontend with a plugin such as Tablesorter.
I'm still a novice at programming. Would like to know how I can make a sorting list for my website.Now by sorting list I mean a list on my website that has a couple of columns and rows, which the user can sort to his preference. here is an example: http://www.rugbyworldcup.com/statistics/season=2011/type=Points/team=0/player=0/statistics/index.html
Thank You
You want a sortable table. Check out the DataTables jQuery plugin. It will take a table and make it sortable and a ton of other things, and with only a 1-line config.
