Form to redirect to different URLs based on the selected option item


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>'

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="" selected>Option1</option>
    <option value="">Option2</option>
    <option value="">Option3</option>


And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val();
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
