这是我的 js 代码:
function validate_reg() {
try {
if (document.getElementById('txtFname').value == "") {
alert("enter 2");
document.getElementById('lblFnameError').style.color = "red";
document.getElementById('lblFnameError').innerHTML = "Error : Enter First NameD.";
document.getElementById('txtFname').focus();
validate_reg_suc = false;
return false;
}
validate_reg_suc = true;
alert("done");
} catch (exc) {
alert("Error : " + exc);
return false;
}
}
我的 html :

js在html之后调用,但仍然出现这个错误
