搜索框-仅第一个选项有效

Question

I have a search box with an option to 'search catalog' and 'search site', which go to different urls. I can only get the 'search catalog' option to work. 'Search site' just goes to the same catalog url rather than to the homepage. I think there is an issue with the onchange, but I really don't know what I'm doing so I'd appreciate any help. Thank you!

<!-- search -->
<div id="search">
    <a href="#" class="searchBtn"><span class="icon-search icon-white"></span></a>
    <div class="search">
        <form id="searchform" action="http://wilkinson.opac.marmot.org/Union/Search/" method="get">
            <select style="width: 150px;  background: none;" onchange="if(this.value == 1){jQuery('#searchform').attr('action','http://wilkinson.opac.marmot.org/Union/Search?searchsource=local/'); }else{ jQuery('#searchform').attr('action', '<?php echo home_url(); ?>'); }">
                <option value="1">Search Catalog</option>
                <option value="2">Search Site</option>
            </select>
            <input name="lookfor" maxlength="20" class="inputbox" type="text" size="20" value="<?php echo __( 'SEARCH ...', THEMENAME );?>" onblur="if (this.value=='') this.value='<?php echo __( 'SEARCH ...', THEMENAME );?>';" onfocus="if (this.value=='<?php echo __( 'SEARCH ...', THEMENAME );?>') this.value='';" />
            <input type="submit" id="searchsubmit" value="go" class="icon-search"/>
        </form>
    </div>
</div>
<!-- end search -->

Your redirect code is working just fine, you just need to have a page that can actually return search results. What I've done on other sites is to use Google's search api. Since you're a public library, you can actually get them for free. Take a look at Google's custom search: https://support.google.com/customsearch/answer/72325?hl=en
