as gjutras suggested, but some browser are still too stupid to handle the DOM, they sometimes work with:<br />
&nbsp; document.forms[0].Options1<wbr />.options[d<wbr />ocument.fo<wbr />rms[0].Opt<wbr />ions1.sele<wbr />ctedIndex]<wbr />.setAttrib<wbr />ute('selec<wbr />ted',false<wbr />);<br />
&nbsp; document.forms[0].Options1<wbr />.options[n<wbr />ewIndex].s<wbr />etAttribut<wbr />e('selecte<wbr />d',true);<br />
<br />
Keep in mind that forms[0] depend on your number of forms in the page, I'd use an id= attribute for the select tag and the get this object with document.getElementById().<wbr />

What is the Javascript code to set a select index

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.
