¿Cómo funciona Select2 en jQuery para datos remotos?

How does Select2 work in jQuery for remote data?

Select2 will pass any options in the ajax object to jQuery’s $.ajax function, or the transport function you specify. For remote data sources only, Select2 does not create a new element until the item has been selected for the first time.

When using Select2 with remote data, the HTML required for the select is the same as any other Select2. If you need to provide default selections, you just need to include an option for each selection that contains the value and text that should be displayed. You can configure how Select2 searches for remote data using the ajax option.

You may wish to set a pre-selected default value for a Select2 control that receives its data from an AJAX request. To provide default selections, you may include an for each selection that contains the value and text that should be displayed: To achieve this programmatically, you will need to create and append a new Option.

New options can be added to a Select2 control programmatically by creating a new Javascript Option object and appending it to the control: The third parameter of new Option (…) determines whether the item is “default selected”; i.e. it sets the selected attribute for the new option.

I am using jQuery jTable to show a data from db which is working fine. I need to reload jTable on selecting an option in dropdown. I am trying to do $ (‘#TableContainer’).jtable (‘load’); but this is not working. Is there a way to reload the table on change event?

and turn it into this… Select2 will register itself as a jQuery function if you use any of the distribution builds, so you can call .select2 () on any jQuery selector where you would like to initialize Select2. The DOM cannot be safely manipulated until it is “ready”.

Once an has been created, it will remain in the DOM even if the selection is later changed. Select2 will issue a request to the specified URL when the user opens the control (unless there is a minimumInputLength set as a Select2 option), and again every time the user types in the search box.

With Select2 v4.0.0+ it became easier. You can make this work, by having your ajax function also return the search term, as the first result in the result list. The user can then select that result as a tag. Thanks for contributing an answer to Stack Overflow!

The current search query will be passed in through the params option: Select2 uses the transport method defined in ajax.transport to send requests to your API. By default this transport method is jQuery.ajax, but it can be easily overridden:

When users filter down the results by entering search terms into the search box, Select2 uses an internal “matcher” to match search terms to results. You may customize the way that Select2 matches search terms by specifying a callback for the matcher configuration option.

This is done for performance reasons. Once an has been created, it will remain in the DOM even if the selection is later changed. Select2 will issue a request to the specified URL when the user opens the control (unless there is a minimumInputLength set as a Select2 option), and again every time the user types in the search box.

Select2 will register itself as a jQuery function if you use any of the distribution builds, so you can call .select2 () on any jQuery element where you would like to initialize Select2. You can optionally pass an object containing all of the options that you would like to initialize Select2 with. Can default options be set for all dropdowns?

I’d like to pass the ID of an element into a function which then calls jQuery. However, I’m stumped as to how to actually take the ID variable and concatenate it with other text inside the jQuery statement. For example, this returns an error:

To provide default selections, you may include an for each selection that contains the value and text that should be displayed: To achieve this programmatically, you will need to create and append a new Option. Select2 supports pagination (“infinite scrolling”) for remote data sources out of the box.

This issue occurs because Bootstrap modals tend to steal focus from other elements outside of the modal. Since by default, Select2 attaches the dropdown menu to the element, it is considered “outside of the modal”. To avoid this problem, you may attach the dropdown to the modal itself with the dropdownParent setting:

Define the ajax option in select2 () method while initializing the element. Initialize results with the return response. View the official documentation for more details. You can view this tutorial to know how to load data using PDO in select2.
