[javascript] Redirect form to different URL based on select option element

new to JavaScript seeking some help. I have a form with a select drop down with 5 options. Option1 Option2 option3 Option4 Option5'

I need to have the form to redirect to another url if any of the options are selected apart from Option 1 which should be the default one on page load.

Thank you in advance

I only used the following

<form action="" id="main" name="main" method="get" onChange="top.location.href=this.options[this.selectedIndex].value;" value="GO">

<select id="Region" name="Region" tabindex="7">
   <option value="/url">Option1</option>
   <option value="/url">Option2</option>
   <option value="/url">Option3</option>
   <option value="/url>Option4</option>
   <option value="" selected="selected">Option5</option>'
</select>

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

you can use this simple way

<select onchange="location = this.value;">
                <option value="/finished">Finished</option>
                <option value="/break">Break</option>
                <option value="/issue">Issues</option>
                <option value="/downtime">Downtime</option>
</select>

will redirect to route url you can direct to .html page or direct to some link just change value in option.
