</form>
这是我的JavaScript函数-
and here is my javascript function -
function checkemptyreport()
{
var firstname = document.getElementById("FirstName").value;
var lastname = document.getElementById("LastName").value;
var fathername = document.getElementById("FatherName").value;
var village = document.getElementById("Village").value;
var district = document.getElementById("District").value;
if((firstname=="") && (lastname == "") && (village == "") && (fathername == "") && (district == "") )
{
alert("Enter Atleast One field");
document.getElementById("FirstName").focus();
return false;
}
else
{
alert(2);
//document.forms["report"].submit();
document.form["report"].action = "/reportbeanservlet";
//document.location = "reportbeanservlet";
return true;
}
}
推荐答案
将搜索按钮的类型更改为提交"(类型按钮不提交表单)，它将提交该表单.或者，您可以:
Change the type of the search button to "submit" (type button does not submit a form), and it will submit the form. Or you can do:
document.form["report"].submit();
在checkemptyreport()函数内部.
