1.獲取文本區域<textarea/>中內容.
<textarea id="comment" name="comment" rows=7 cols=50></textarea>
function getsumit(){
var comments=document.all["comment"].value;
if(comments == '')
{
alert("請輸入文本區域值!");
}
}
2.判斷是否是數字
function getsumit(){
var numId = document.getElementById("NumId ").value;
//轉換爲整型
var Id = parseInt(numId);
if(numId == '')
{
alert("空!");
return false;
}
else
{
if(isNaN( Id))
{
alert("不是數字");
return false;
}
else
{
return true;
}
}
}
3.關閉本頁面刷新上一級頁面
if(Assess_tag == ' ')
{
var factvalue = <%=request.getParameter("factScore")%>;
var ASSESS_GRADEVALUE = <%=request.getParameter("ASSESS_GRADEVALE")>;
var ftvalue = parseInt(factvalue);
var ASSESS_GRADEVALUE = parseInt(ASSESS_GRADEVALUE);
var jiaftvalue = ASSESS_GRADEVALUE - ftvalue;
if(Gravalue > jiaftvalue)
{
alert("您輸入的分值只能小於或等於 "+ jiaftvalue);
return false;
}
else
{
document.insertchall.action="AssessRequest?year=<%=year%>&month=<%=month%>";
document.insertchall.submit();
window.close();
opener.document.location="<%=path%>/newcontinent/AssessInfo.jsp?year=<%=year%>&onth=<%=month%>";
return true;
}
}
