    <p>i'm developing a meta search engine website, <a href="http://soogle.net/" rel="nofollow noreferrer">Soogle</a> and i've used JS to populate select menu..</p> <p>Now, after the page is loaded none of engines is loaded by default, user needs to select it on his own or [TAB] to it..</p> <p>Is there a possibility to preselect one value from the menu via JS after the page loads?</p> <p>This is the code:</p> <p>Javascript:</p> <pre><code>// SEARCH FORM INIT function addOptions(){ var sel=document.searchForm.whichEngine; for(var i=0,l=arr.length;i&lt;l;i++){ sel.options[i]=new Option(arr[i][0], i); } } function startSearch(){ var searchString=document.searchForm.searchText.value; if(searchString.replace(/\s+/g,"").length &gt; 0){ var searchEngine=document.searchForm.whichEngine.selectedIndex, finalSearchString=arr[searchEngine][1]+searchString; window.location=finalSearchString; } return false; } function checkKey(e){ var key = e.which ? e.which : event.keyCode; if(key === 13){ return startSearch(); } } // SEARCH ENGINES INIT var arr = [ ["Web", "http://www.google.com/search?q="], ["Images", "http://images.google.com/images?q="], ["Knowledge","http://en.wikipedia.org/wiki/Special:Search?search="], ["Videos","http://www.youtube.com/results?search_query="], ["Movies", "http://www.imdb.com/find?q="], ["Torrents", "http://thepiratebay.org/search/"] ]; </code></pre> <p>HTML:</p> <pre><code>&lt;body onload="addOptions();document.forms.searchForm.searchText.focus()"&gt; &lt;div id="wrapper"&gt; &lt;div id="logo"&gt;&lt;/div&gt; &lt;form name="searchForm" method="POST" action="javascript:void(0)"&gt; &lt;input name="searchText" type="text" onkeypress="checkKey(event);"/&gt; &lt;span id="color"&gt;&lt;/span&gt; &lt;select tabindex="1" name="whichEngine" selected="Web"&gt;&lt;/select&gt; &lt;br /&gt; &lt;input tabindex="2" type="button" onClick="return startSearch()" value="Search"/&gt; &lt;/form&gt; &lt;/div&gt; &lt;/body&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
