Line: 670 which is startdate.value = hiddenstart.value;
But I am getting an unaught TypeError:
Cannot read property 'value' of null in the javascript console.
问题是这只发生在 Chrome 中，没有其他浏览器。
有人可以看看，让我知道是否有什么我可以改变来解决这个问题。
<script language="Javascript">
function calcEndDate(cal) {
var startdate = document.getElementById("<?php echo columnnames($value); ?>_0");
var hiddenstart = document.getElementById("hiddenstart");
startdate.value = hiddenstart.value;
var date = cal.date;
var time = date.getTime();
var hiddenend = document.getElementById("hiddenend");
var date2 = new Date(time);
hiddenend.value = date2.print("%d-%b-%Y 23:59");
var enddate = document.getElementById("<?php echo columnnames($value); ?>_1");
enddate.value = hiddenend.value;
return true;
}
function calcUpdateEndDate() {
var enddate = document.getElementById("<?php echo columnnames($value); ?>_1");
var hiddenend = document.getElementById("hiddenend");
enddate.value = hiddenend.value;
}
</script>

给我一些提示或指导我哪里错了。
