如何计算两个日期之间的差异，并在字段名称=“天”中写下差异？

Answer 1

计算2个日期之间的差异并将值分配给另一个文本框

<input type="text" id="val1"/>
<input type="text" id="val2"/>
<input type="text" id="val3" />
<script>


function myFun() {

var x2=document.getElementById("val1").value;
var x3=document.getElementById("val2").value;
var msPerDay = 1000*60*60*24;
d1=new Date(x2);
d2=new Date(x3);
var x4=document.getElementById("val3");
var dd=( ((d1 - d2) / msPerDay).toFixed(0)+"days" );
    x4.value=dd;
    }

</script>
<input type="submit" id="myid" onclick="myFun()" value="get difference"/>
