Create select box options javascript

Author: Extra_rus On: 04.07.2017

It binds to a textbox, and as you type in the textbox the select list gets filtered to match what you are typing.

Live example or in a new window: You can play around with it on jsbin: When you invoke the function on a select object, it finds all child option tags and saves their text and values into an array.

This array is saved to the select object itself as a HTML5 custom data attribute, called data-options. Then, when a change or keyup event fires on the associated textbox, the select list is emptied, and for any entries in the array that match the search text a new option element is created.

When user selects a step this is designed to give next step to try and from there next one in a flow chart style. I want to add a textbox to which the selections will auto populate. After troubleshooting they should be able to copy all selected items from the text box. Can anyone help me with a code which will auto populate all user selected items from the flow into a text box.

Please find the code I used for the troubleshooting guide. Any help will highly appreciated.

You can use it on many select multiple boxes. You just need to bind each one, for example: Great script, thank you for posting it. There was one small niggle in our case — so many options in the select element that after the first keypress there was a significant pause while the script found every option with that letter in.

At line 9 I added: That makes the filter only kick in once there are at least two characters in the text field. Hi there, I am currently missing one feature, which is the saving of already selected options.

Is there an easy way to preserve it? Yes, I am a complete newbie to jquery…. You can make the following two modifications to preserve the class es on the option tags: Works perfectly, thank you!!

Ok, one more question: I have cliffs natural resources stock price move the scrollbar a bit to make the items appear.
