Question

我在php中面临一些问题，

<input  class="form-control" placeholder="Start Time"
value="'.date("H.i").'" type="text" name="starttime[]" id="starttime"/>
</div>
<div class="col-lg-4">
<input  class="form-control" name="endtime[]" id="endtime" onchange="myfunction1()" value="00.00" type="text" placeholder="End Time">

这是我的ajax代码，当我更改结束时间时必须显示其他文本框

<input class="form-control" name="kmcost" id="exkms" type="text" placeholder="Cost">

但是单个条目工作但第二个条目（数组）不是我的javascript代码在这里请帮助我..

我的javascript在这里..

function myfunction1()
{
    var ftime = document.getElementById("starttime").value;
    var etime = document.getElementById("endtime").value;

    var timeanswer = etime - ftime;

    var localtottme = document.getElementById("textbox3").value;
    if(timeanswer > 8)
    {
        var totextme = timeanswer-8;
    }
   var exkms = document.getElementById('exkms');
exkms.value=totextme;
}

Answer 1

试试这个：

function myfunction1()
{
    // fetch value of element as string, x2
    var ftime = document.getElementById("starttime").value;
    var etime = document.getElementById("endtime").value;

    // fetch hour as string, then convert to integer, x2
    ftime = parseInt(ftime.split(':')[0]);
    etime = parseInt(etime.split(':')[0]);

    // calculate hour difference, initialize remainder variable to 0
    var hourDifference = etime - ftime;
    var eightHourRemainder = 0;

    // check if hour difference is more than 8, if so then calculate remainder variable
    var localtottme = document.getElementById("textbox3").value;
    if(hourDifference > 8)
    {
        eightHourRemainder = hourDifference - 8;
    }

    // set element value to remainder variable
    var exkms = document.getElementById('exkms');
    exkms.value=eightHourRemainder;
}

javascript数组不正常
