Datatables data search

We are using data table for displaying data wit rows of data and 60 columns with multi select drop down option for individual columns, when we are searching in the data table it is taking so much time for filtering, if their are any other ways to speedup the search and data loading into the data table please inform.

Thank you in advance. The same problem with me, my table is a server-side processing. Every time I keypress the datatables activates ajax. I suggest closing the previous ajax every time you keypress in the search bar.

If you have server-side processing enabled, then yes, every search key press will trigger an Ajax request - that's how server-side processing works its gets the data to display for every draw from the server. There is the searchDelay option which can be useful when server-side processing if you want to introduce a delay to allow for key presses.

If the problem is caused by server side reloading on each keypress you could always debounce the search box so that the ajax call will only be triggered after a short delay after the user has stopped typing rather than every keypress.

I've done this before using underscorejs with this function:. Calling this with something like debounceSearch ' example' will cause the ajax call to be triggered only if there is is a pause between keyup events of ms. I've found it can reduce the number of ajax calls a bit over the searchDelay option. When using rduncecb code noticed that it doesn't completely match default datatable's search behaviour e.

This way search continue working same way as original DT as we are re-using original event handler which is actually same at the moment for all listed 'DT.

Categories The ability to search a table for data is core to the concept of DataTables, as it allows data to be easily accessed by users.

This method provides the ability to control the global search of a table through the API. The global search is performed across all searchable columns see columns. If data is found matching in any column, then the whole row is matched and shown in the result set.

Searching on individual columns can be performed using the columns. DataTables has a built in search algorithm referred to as "smart" searching and is designed to make searching the table data, easy to use for the end user. A smart search in DataTables provides the following abilities:. The smart search ability of DataTables is performed using a regular expression and can be enabled or disabled using the third parameter of this method.

If you wish to use a custom regular expression, for example to perform whole word exact matching, you would need to enable the regular expression option second parameter and disable the smart search option third parameter to ensure that the two do not conflict. Note that this search ability in DataTables is actually technically a filter since it is subtractive.

However, we term is a search to avoid naming conflict with the filter helper method. Please be aware that this method sets the search to apply to the table only - it does not actually perform the search. In order to have the search performed and the result shown, use the draw method, which can be called simply as a chained method of the search method's returned object - for example table. This is to provide the ability to queue multiple changes before performing a draw.

Get the currently applied global search. If there is more than one table in the API's context, the search term of the first table will be returned. Use table if you require the search term of a different table in the API's context.

Set the global search to use on the table. Note this doesn't actually perform the search, but rather queues it up - use draw to perform the search and display the result. Perform smart search default, true or not false. See below for a description of smart searching. Note that to perform a smart search, DataTables uses regular expressions, so if enable regular expressions using the second parameter to this method, you will likely want to disable smart searching as the two regular expressions might otherwise conflict and cause unexpected results.
