【问题描述】:
大家晚上好, 我想知道如何从第 1 页显示导入数据到第 2 页中的视图,从 input 调用函数 GetRoute() 。 这是我的代码: html第1页:
<div> Add Destination</div>
<div>
<input id="travelto" type="text" name="name" value="Oving, UK" />
<input type="button" value="Add" onclick="PushDestination()" />
<a href="#" onclick="setDestination('Tagmere, UK')">Tagmere, UK. </a>
<a href="#" onclick="setDestination('Bosham, UK')">Bosham, UK</a>
</div>
<div id="destinations"></div><br />
Source : <input id="travelfrom" type="text" name="name" value="Chichester, UK" /> <br /> <br />
<input type="button" value="Calculate" onclick="GetRoute()" />
html页面2 结果将显示在第二页的表格中:
<div id="dvDistance">
<table id="tblResults" border="1" cellpadding="10">
<tr>
<th> Start </th>
<th> End </th>
<th> Distance </th>
<th> Duration </th>
</tr>
</table>
</div>
我的 javascript 函数:
function GetRoute() {
directionsDisplay.setMap(map);
source = document.getElementById("travelfrom").value;
destination = document.getElementById("travelto").value;
var waypoints = [];
for (var i = 0; i < locations.length; i++) {
var address = locations[i];
if (address !== "") {
waypoints.push({
location: address,
stopover: true
});
}
}
var request = {
origin: source,
destination: waypoints[0].location,
waypoints: waypoints, //an array of waypoints
optimizeWaypoints: true, //set to true if you want google to determine the shortest route or false to use the order specified.
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
var dvDistance = document.getElementById("dvDistance");
var distance = 0;
var minute = 0.00;
response.routes[0].legs.forEach(function (item, index) {
if (index < response.routes[0].legs.length - 1) {
distance = distance + parseInt(item.distance.text);
minute = parseFloat(minute) + parseFloat(item.duration.value / 60);
tbl = document.getElementById("tblResults");
var row = tbl.insertRow(1);
var cell = row.insertCell(0);
cell.innerText = source;
var cell = row.insertCell(1);
cell.innerText = item.end_address;
var cell = row.insertCell(2);
cell.innerText = distance;
var cell = row.insertCell(3);
cell.innerText = minute.toFixed(2) + " min";
}
});
directionsDisplay.setDirections(response);
}
else {
}
})
};
我必须显示结果才能显示在第二页,从第一页获取数据。 谢谢,
