調用提交的Vaidation函數。Javascript驗證不起作用(onSubmit)
HTML
<input type="submit" class="submit" value="submit">
JS
window.load = function() {
var form = document.getElementById('form');
form.onsubmit = function(e) {
return validate(); // will be false if the form is invalid
}
}
驗證()
function validate() {
var x = document.forms["form"]["fname"].value;
var y = document.forms["form"]["pname"].value;
var email = document.forms["form"]["email"].value;
var phone = document.forms["form"]["phone"].value;
var date = document.forms["form"]["date"].value;
var month = document.forms["form"]["month"].value;
var year = document.forms["form"]["year"].value;
return false;
alert('wass');
if (x==null || x == "" || isNaN(x) == false) {
alert("Check Name, It can't have numbers. You can use Roman numbers.");
return false;}
else if (y == null || y == "") {
alert("Picture Name must be filled out");
return false;
}
else if(email == '' || email.indexOf('@') == -1 || email.indexOf('.') == -1)
{
alert("Insert valid Email Address");
return false;
}
else if(phone == ''|| phone <1000000000 || phone >9999999999){
alert("Enter valid phone number");
return false;
}else if(date =='' || date<01 || date >31){
alert("Enter valid Date ");
return false;
}else if(month =='' || month<1 || month >12){
alert("Enter valid Month ");
return false;
}else if(year =='' || year<1800 || year >2016){
alert("Enter valid Year ");
return false;
}
//Function used to make colors red instead of individual codelines
function makeRed(inputDiv){
inputDiv.style.backgroundColor="#AA0000";
//inputDiv.parentNode.style.backgroundColor="#AA0000";
//inputDiv.parentNode.style.color="#FFFFFF";
}
//Function made to clean the divs when the validation is met.
function makeClean(inputDiv){
inputDiv.style.backgroundColor="#FFFFFF";
inputDiv.parentNode.style.backgroundColor="#FFFFFF";
inputDiv.parentNode.style.color="#000000";
}
}
形式仍然被提交。可能的問題?
