jquery

问题 This question has been asked numerous times but never really answered specifically without the use of a third party application.

问题 In jquery, how can I show a link that is generated on the fly inside a table? I will have the link stored in my database, but I want it to be shown by a name and then take me to the correct link accordingly.

I would like to remotely simulate a change (i.e. without the user clicking in the select menu) in the dropdown menu which will activate the Javascript to set the next dropdown's options.
