var latitude = document.getElementById("latitude");
var longitude = document.getElementById("longitude");
var myCenter = new google.maps.LatLng(latitude, longitude);
var marker;
function initialize()
{
var mapProp = {
center: myCenter,
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
marker = new google.maps.Marker({
position: myCenter,
animation: google.maps.Animation.BOUNCE
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
var latitude
没有获得值
这里我从下面的ID中获取值,
<div class="map" id="googleMap" style="width:100%;height:260px;overflow:hidden;"></div>
<div id="latitude"><?php echo $itemData['130']; ?></div>
<div id="longitude"><?php echo $itemData['131']; ?></div>
在$itemData['130']
和$itemData['130']
中,价值正常,
我不知道我做错了什么?

你得到的对象。如果您想要PHP正在回显的值,请使用.innerHTML
:
var latitude = document.getElementById("latitude").innerHTML;
答案 1 :(得分:3)
This code will work try this
function initialize() {
var latitude = document.getElementById("latitude").innerHTML;
var longitude = document.getElementById("longitude").innerHTML;
var myCenter = new google.maps.LatLng(latitude, longitude);
var marker;
var mapProp = {
center: myCenter,
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
marker = new google.maps.Marker({
position: myCenter,
animation: google.maps.Animation.BOUNCE
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);

nodeValue
函数来获取它,但JQuery和其他库中提供了类似的功能。)代码段:
var marker;
function initialize()
{
var latitude = nodeValue(document.getElementById("latitude"));
var longitude = nodeValue(document.getElementById("longitude"));
var myCenter = new google.maps.LatLng(latitude, longitude);
var mapProp = {
center: myCenter,
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
marker = new google.maps.Marker({
position: myCenter,
animation: google.maps.Animation.BOUNCE
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
//nodeValue: Extract the text value of a DOM node, with leading and trailing whitespace trimmed
var nodeValue = function(node, defVal) {
var retStr="";
if (!node) {
return (typeof defVal === 'undefined' || defVal === null) ? '' : defVal;
}
if(node.nodeType==3||node.nodeType==4||node.nodeType==2){
retStr+=node.nodeValue;
}else if(node.nodeType==1||node.nodeType==9||node.nodeType==11){
for(var i=0;i<node.childNodes.length;++i){
retStr+=arguments.callee(node.childNodes[i]);
}
}
return retStr;
};

检查一下:
var latitude = document.getElementById("latitude").innerHTML;
var longitude = document.getElementById("longitude").innerHTML;
注意:这个将产生纬度和经度。您使用的那个将产生对象而不是值。
