你可以连接时间跨度查询字符串和filePath变量。



Ex。



var dNow = new Date（）;

filePath = document.forms [0] .Ins_File.value +？ts =+ dNow.getHours （）+ dNow.getMinutes（）+ dNow.getSeconds（）;

you can concatenate time span Query string with filePath variable.

Ex.

var dNow = new Date();
filePath = document.forms[0].Ins_File.value+ "?ts="+ dNow.getHours()+ dNow.getMinutes()+ dNow.getSeconds();
