远离Google地图并将其乘以两种费率中的一种

标签： javascript google-maps maps

我在网上发现这个代码几乎可以满足我的需求。问题是我需要它根据用户是想要当天交货还是当天紧急交货给我一个价格。我不能让它工作。

表单应该有两个地址，计算它们之间的距离，如果选择了相同的日期，则将它们乘以1英镑;如果选择了相同的日期，则为1.20英镑。

session_start();
$rate = 1;
$urgent = 1.2;

基于你所说的 - 摆脱

<?php
session_start();
$rate = 1;
$urgent = 1.2;

并将computeTotalDistance函数更改为

function computeTotalDistance(result) {
    var rate = 1;
    var urgent = 1.2;
    var total = 0;
    var cost;
    var myroute = result.routes[0];
    for (i = 0; i < myroute.legs.length; i++) {
        total += myroute.legs[i].distance.value;
    }
    total = total / 1000;
    /*Start Calculating Distance Fair*/
    if (document.getElementById('sameday').checked == true) {
        cost = total * rate;
    } else if (document.getElementById('samedayurgent').checked == true) {
        cost = total * urgent;
    }
    cost = Math.round(cost * 100) / 100;
    /*Distance Fair Calculation Ends*/
    document.getElementById("total").innerHTML = "Total Distance = " + total + " km and FARE = £" + cost;
}

正如Markai指出的那样

<input type="radio" name="post-type" id='sameday' checked> Same Day
<br>
<input type="radio" name="post-type" id='samedayurgent'> Same Day Urgent
