    <p>I want to add new markers after removing markers from Google maps. However, my code isn't doing what I expected. After the removal, no new marker could be added.</p> <p>Code <strong>snippet</strong>:</p> <pre><code>function codeAddress(coordinates) { console.log("called"); var myLatlng = new google.maps.LatLng(coordinates.lb,coordinates.mb); var marker = new google.maps.Marker({ map: map, position: myLatlng }); markersArray[markerid] = marker; markerid++; } function deleteOverlays() { if (markersArray) { for (i in markersArray) { markersArray[i].setMap(null); } } markersArray = {}; markerid = 0; } function go(){ var cMin = document.getElementById('costMin').value; var cMax = document.getElementById('costMax').value; var religion = document.getElementById('religion').value; // remove previous marker layer deleteOverlays(); console.log(coorList.length); for(var i = 0; i &lt; coorList.length; ++i){ //codeAddress(); if(religion != ""){ if(coorList[i].cost1 &gt;= cMin &amp;&amp; coorList[i].cost1 &lt;= cMax &amp;&amp; coorList[i].religion.toLowerCase() ==religion.toLowerCase()){ codeAddress(coorList[i]); } } else{ if(coorList[i].cost1 &gt;= cMin &amp;&amp; coorList[i].cost1 &lt;= cMax){ codeAddress(coorList[i]); } } } } &lt;input id="costMin" type="textbox" &gt; &lt;input id="costMax" type="textbox" &gt; &lt;input id="religion" type="textbox" &gt; &lt;input type="button" value="Go" onclick="go();"&gt; </code></pre> <p>When I placed a console.log("called") within the codeAddress() function, it seems like the function is not called at all after the click. If I get rid of deleteOverlays() from the go() function, the codeAddress will be called. Is there anything wrong with my code?</p>

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.
