Google静态地图API实现代码_javascript技巧

function getStaticMap() {
var url = 'http://maps.google.com/maps/api/staticmap?center=';
if (getObj('chkUseNum').checked) {
url += encodeURI(getObj('txtX').value) + ',' + encodeURI(getObj('txtY').value);
}
else {
url += encodeURI(getObj('txtCenter').value);
}
url += '&zoom=' + getObj('txtZoom').value;
url += '&size=' + getObj('txtWidth').value + 'x' + getObj('txtHeight').value;
url += '&format=' + getObj('selImageType').options[getObj('selImageType').selectedIndex].text;
url += '&maptype=' + getObj('selMapType').value;
var trs = getObj('tdFlagList').getElementsByTagName('tr');
for (var i = 1; i < trs.length; i++) {
var txtFlagAddress = trs[i].getElementsByTagName('input')[0];
if (txtFlagAddress.value == '') {
continue;
}
var selFlagColor = trs[i].getElementsByTagName('select')[0];
var selFlagSize = trs[i].getElementsByTagName('select')[1];
var txtFlagLabel = trs[i].getElementsByTagName('input')[1];
url += '&markers=size:' + selFlagSize.value;
url += '|color:' + selFlagColor.options[selFlagColor.selectedIndex].text;
url += '|label:' + txtFlagLabel.value;
url += '|' + encodeURI(txtFlagAddress.value);
}
url += '&sensor=false';

getObj('txtImageUrl').value = url;
getObj('imgMap').src = url;
getObj('imgMap').style.display = 'block';
}

function addMapFlag(o) {
var tr = o.parentNode.parentNode;
var newTr = tr.parentNode.appendChild(tr.cloneNode(true));
var aList = newTr.getElementsByTagName('a');
aList[0].style.display = 'inline';

function chkUseNum_onclick(o) {
