如何在用户单击提交按钮时在两点之间绘制一条折线,并在用户单击重置按钮时将其重置。我用这段代码在绘图函数()中绘制了一条折线,并使用 onclick()调用了它,但这不起作用,请任何人告诉我我们如何调用该函数并绘制一条折线
<script>
function initialize()
{
....}
function plotting()
{
var stratapps = [
new google.maps.LatLng(17.447246,78.362029),
new google.maps.LatLng(37.50905,-121.974659),
];
var flightPath = new google.maps.Polyline({
path: stratapps,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2,
});
flightPath.setMap(map);
} google.maps.event.addDomListener(window, 'load', plotting);
<button value="plot" onclick="plotting();">Plot</button>
