思路是在window.onload中当检测到加载Roboto字体时，skip掉就可以了。

如下：

 var head = document.getElementsByTagName('head')[0];// Save the original methodvar insertBefore = head.insertBefore;// Replace it!head.insertBefore = function (newElement, referenceElement) {if (newElement.href && newElement.href.indexOf('fonts.googleapis.com/css?family=Roboto') > 0) {console.info('Prevented Roboto from loading!');return;}insertBefore.call(head, newElement, referenceElement);};

完整代码如下：

<script type="text/javascript">var map, geocoder, bounds;//, marker, infowindow;window.onload = function() {var head = document.getElementsByTagName('head')[0];// Save the original methodvar insertBefore = head.insertBefore;// Replace it!head.insertBefore = function (newElement, referenceElement) {if (newElement.href && newElement.href.indexOf('fonts.googleapis.com/css?family=Roboto') > 0) {console.info('Prevented Roboto from loading!');return;}insertBefore.call(head, newElement, referenceElement);};// Creating a new mapvar options = {zoom: 10,center: new google.maps.LatLng(27.9679125,120.7272096),mapTypeId: google.maps.MapTypeId.ROADMAP,panControl: true,streetViewControl: false,scaleControl: true};map = new google.maps.Map(document.getElementById('map_canvas'), options);// Making the Geocoder callgetCoordinates("Parallelweg 2, Groenlo, Netherlands", "PR50S");return true;}// Create a function the will return the coordinates for the addressfunction getCoordinates(address, name) {// Check to see if we already have a geocoded object.
