Hello guys I'm really new to javascript,
I want an alert message to appear if the user pressed on check,
to see if the input was right or wrong,
and I've been trying for so long but it's not working no matter what, it's just a simple code.
I'm really suffering with this for hours, trying to figure why no alert message appears when I press on the check button.
Would be really grateful for any help or any tip, many thanks!!
function myFunction() {
var x = document.getElementById("f").value;
var z = document.getElementById("s").value;
var c = document.getElementById("e").value;
var v = document.getElementById("p").value;
var b = document.getElementById("p1").value;
if (isNaN(x) || x = "") {
alert("First Name input is wrong");
} else {
alert("Input is ok");
}
if (isNaN(z) || z = "") {
alert("Second Name input is wrong");
} else {
alert("Input is ok");
}
if (isNaN(c) || c = "") {
alert("Email input is wrong");
} else {
alert("Input is ok");
}
if (v = "") {
alert("Input is wrong");
} else {
alert("Input is ok");
}
if (b = "" || b !== v) {
alert("Password does not match");
else {
alert("Input is ok");
}
}
}

You have a few syntax errors in your function.
Javascript requires == (or ===) for comparisons.
You also need to add a curly brace } before the else after "Password does not match", and remove one after the following "Input is ok".

form validation not working along with form action

I have a registration form which SHOULD check the inputting data according to each function i have created(inside validation.js file) and after everything is ok then it should return all the data to the .php file which will save inthe phpmyadmin database.
However it is not working
Test1: validation is working (alone not included the action=.php)
Test2: without validation the data is storing in the database(phpmyadmin)
Test3: with validation and with action=.php) its not working the validation part
Please help me.

It appears your validation method always returns false. If the code called by onSubmit returns false, the action will not be executed. The same is true for onclick and other event functions.
Once you've evaluated all the conditions to be valid, you should return true to tell the form that it can take over and do its thing.

Form validation without error on IE

I have a html code saved as a php, the form validation works in google chrome but not in IE. In IE after I hit the submit button, the page automatically goes to process form regardless of errors.
This is my code:

When you look at the console in IE’s developer tools (F12), you will see that there is an error message about undeclared variable lName. This causes the error checking to be aborted.
You have several lines like
//var lName = document.forms["orderForm"].lastName.value;//last name validation
Since // starts a comment in JavaScript, the line has no effect. The variable lName is not declared or defined elsewhere either.
So you need to remove those // comment starters. Note that the code does not work in Chrome either; you may have tested a different version in Chrome, or misinterpreted some behavior.
In the console, you can also see a message for line 237 about “unexpected identifier”. It is actually a serious HTML markup error; IE reports some of such errors, in a strange way. The error is that a tr element has an input element as child, which is forbidden in HTML syntax. This is why the Submit Order and Reset Form appear on top of each other and not on the same row as intended. (For usability, the Reset Form button should be removed, but I digress.)

Absence of an error description doesn't imply the absence of an error. Change your error handling code to this:
If Err Then
response.write Err.Number & "<br><br>There was an error on this page."
Else
response.write "Thank you, your message has been sent."
End If
Are you able to connect from your webserver to the mailserver on port 465?
telnet smtp.gmail.com 465
Are you using correct credentials?
Do you have access to the mailserver logs? What do they say about connections from that page? If you don't have access to the actual mailserver, can you set up a dummy server and temporarily point the page to that server, so you can check if the code is working in principle?

JavaScript checking & adding text to a table dynamically on submit button click

Basically my HTML looks like this:
<form method="post" name="htmlform" onsubmit = "checkFields()">
<table style="width: 479px;" border="30" cellspacing="3" cellpadding="10">
<tbody>
<tr>
<td valign="top"><span id="firstNameSpan" >First Name *</span></td>
<td valign="top"><input type="text" name="first_name" id="first_name"
size="30" maxlength="50" /></td>
</tr>
<tr>
<td valign="top"><span id = "lastNameSpan" >Last Name *</span></td>
<td valign="top"><input type="text" name="last_name" size="30" maxlength="50"/>
/td>
</tr>
<tr>
<td style="text-align: center;" colspan="2"><input type="radio" name="sex"
value="male" /> Male <input type="radio" name="sex"
value="female" /> Female</td>
</tr>
<tr>
<td style="text-align: center;" colspan="2"><input type="submit" value="submit"
/></td>
</tr>
</tbody>
</table>
</form>
When the form is submitted, the onsubmit() event checks if first_name textfield is blank, if it is then the label or span to its left is appended to output "first name*" + " you must enter a first name" and similarly for last name and sex.
The problem is that the text in the table does not update with appendchild. When I enclosed the statement in an alert for debugging the message is appended then disappears.
The JavaScript code is below for the onsubmit = "checkFields()".
function checkFields() {
var firstName = document.getElementById("first_name").value;
var lastName = document.getElementById("last_name").value;
if (firstName == "") {
//<span style='color:red'> Please enter a first name </span>
var nameHint = " Please enter a first name";
var node = document.getElementById("firstNameSpan");
//alert(node.appendChild(document.createTextNode(nameHint)) );
//not working
node.appendChild(document.createTextNode(nameHint));
} if (lastName == "") {
//additional code
}
}
Thanks in advance, your help is much appreciated. Also are there any JavaScript debuggers?

I believe your sample code is not working due to incorrect html. document.getElementById("last_name") will return undefined.
http://jsfiddle.net/5E6my/1/

Thanks all, Im getting the ropes of JFiddle the split screen is very useful although the error messages are not useful for debugging. Here is the completed code (1) HTML (2) JavaScript.
<form method="post" name="htmlform" onsubmit="return checkFields();">
<table style="width: 479px;" border="30" cellspacing="3" cellpadding="10">
<tbody>
<tr>
<td valign="top"><span id="firstNameSpan" >First Name *</span></td>
<td valign="top"><input type="text" name="first_name" id="first_name"
size="30" maxlength="50" /></td>
</tr>
<tr>
<td valign="top"><span id = "lastNameSpan" >Last Name *</span></td>
<td valign="top"><input type="text" name="last_name" id="last_name" size="30"
maxlength="50" /></td>
</tr>
<tr>
<td style="text-align: center;" colspan="2" id = "sexMessage">
Please select Male or Female*</td>
</tr>
<tr>
<td style="text-align: center;" colspan="2"><input type="radio"
name="sex" value="male" /> Male <input type="radio" name="sex"
value="female" /> Female</td>
</tr>
<tr>
<td style="text-align: center;" colspan="2"><input type="submit" value="submit"
/></td>
</tr>
</tbody>
</table>
</form>
The JavaScript code to react to the onsubmit button's unfilled fields in the form are: (any ways to make this code simpler??)
window.checkFields = function()
{
var firstName = document.getElementById("first_name");
var lastName = document.getElementById("last_name");
if(firstName.value == "")
{
//<span style='color:red'> Please enter a first name </span>
var nameHint = " *Please enter a first name ";
var fnNode = document.getElementById("firstNameSpan");
while(fnNode.firstChild)
{
fnNode.removeChild(fnNode.firstChild)
}
fnNode.appendChild(document.createTextNode(nameHint));
fnNode.style.color="red";
} else{
var nameHint = " First Name *";
var fnNode = document.getElementById("firstNameSpan");
while(fnNode.firstChild)
{
fnNode.removeChild(fnNode.firstChild)
}
fnNode.appendChild(document.createTextNode(nameHint));
fnNode.style.color="black";
}
if (lastName.value == "")
{
//additional code
var nameHint = " *Please enter a last name";
var lnNode = document.getElementById("lastNameSpan");
while(lnNode.firstChild)
{
lnNode.removeChild(lnNode.firstChild)
}
lnNode.appendChild(document.createTextNode(nameHint));
lnNode.style.color="red";
} else{
var nameHint = " Last Name *";
var lnNode = document.getElementById("lastNameSpan");
while(lnNode.firstChild)
{
lnNode.removeChild(lnNode.firstChild)
}
lnNode.appendChild(document.createTextNode(nameHint));
lnNode.style.color="black";
}
var radios = document.getElementsByName("sex");
var radioValue = ""
for(var i=0; i<radios.length; i++)
{
if(radios[i].checked)
{
radioValue = radios[i].value;
}
}
if(radioValue === "")
{
var sexNode = document.getElementById("sexMessage");
var nameHint = "*You did not choose a sex";
while(sexNode.firstChild)
{
sexNode.removeChild(sexNode.firstChild);
}
sexNode.appendChild(document.createTextNode(nameHint));
sexNode.style.color="red";
} else {
var sexNode = document.getElementById("sexMessage");
var nameHint = "Please select Male or Female*";
while(sexNode.firstChild)
{
sexNode.removeChild(sexNode.firstChild);
}
sexNode.appendChild(document.createTextNode(nameHint));
sexNode.style.color="black";
}
return false;
}
The trick is to use as Yury suggested was the onsubmit="return checkfields()" and then in the code block to use window.checkFields = function() { etc.
One question that I have... is JQuery a lot simpler to use, im learning JavaScript before JQuery... should I skip to JQUery instead. Also does JQuery support the AJAX framework?
Much appreciated
