<script type="text/javascript">
// Load the latest version of the Google Data JavaScript Client
google.load('gdata', '2.x', {packages: ['maps']});

// Call function once the client has loaded
google.setOnLoadCallback(onGoogleDataLoad);
</script>
<script type="text/javascript">
var service = new google.gdata.maps.MapsService('docs-example');
listMaps()
function listMaps() {

var entries = feed.getEntries();
for (var i = 0; i < entries.length; i++) {
var entry = entries[i];
var mapTitle = entry.getTitle().getText();
var listItem = document.createElement('li');
var listText = document.createTextNode(mapTitle);
listItem.appendChild(listText);

}
document.body.appendChild(list);
}, errorHandler)
}
function errorHandler(){
alert('error!!!')
}
</script>
</body>
</html>
why ?
thanks
you should put any call to the google stuff inside the onGoogleDataLoad() function to make sure it is not launched before the APIs have finished loading.
function onGoogleDataLoad() {
var service = new google.gdata.maps.MapsService('docs-example');
listMaps()
}
If you check the JS URL with your browser, you get the following result:
var error = new Error("Invalid autoload.");
error.toString = function() { return this.message; }
throw error;
Meaning, there's something wrong with your URL.
加载中,请稍侯......
