Using jQuery, how do you check if there is an option selected in a select menu, and if not, assign one of the options as selected. (The select is generated with a maze of PHP functions in an app I just inherited, so this is a quick fix while I get my head around those :) Joe Lencioni While I'm not sure about exactly what you want to accomplish, this bit of code worked for me. <select id="mySelect" multiple="multiple"> <option value="1">First</option> <option value="2">Second</option> <option value="3">Third</option> <option value="4">Fourth</option> </select> <script type="text/javascript"> $

Javascript to Select Multiple options

问题 I have a form with a select box that allows multiple options. After a user saves these options, it stores them in a database table. I can then read this database table to get the options they chose one again. I need to be able to grab this data from the database, put it into an array, then have the options in that select box to be pre-selected when they go to \"Edit\" their options. Reading the data into an array is fine, and I know how to make a single option selected within a select box,

How can I create an editable dropdownlist in HTML?

陌路散爱 提交于 2019-11-26 12:39:27
问题 I\'d like to create a text field with a dropdown list that lets the user choose some predefined values. The user should also be able to type a new value or select a predefined one from a dropdown list. I know that I can use two widgets for that but in my app it would be more ergonomnic if it was unified in a one widget. Is there a standard widget or do I have to use a third party javascript? How about browser portability? 回答1: The best way to do this is probably to use a third party library.

It's relatively simple, just retrieve the list of passengers from the DB, store it in request scope and forward to the JSP which should
