Please use code tags and put your code in them. It makes it easier on every one.

Your input button calls the function allThatStuff().
Code:

<input type="button" id="button" name="button" onClick="allThatStuff()" value="Determine the Author!">

But you do not have a function by that name. You only have a single function named Code:

 form.input4.onclick = function(){.....}

But even getting that straight wont work when you have things like:
Code:

if input4 = (inputAverage2 + i){
	var Author2="yes"
	var Author2Off = i
}

the if statement S/B Code:

if  ( input4  ==  (inputAverage2 + i) ) {....}

How To Get The Text Within A Textbox Which Is Inside An Iframe?

Similar Tutorials

I use the following code to create a hidden iFrame on a page, dynamically

Code:

var i = document.createElement('iframe');
i.style.display = 'none';
i.onload = function() { i.parentNode.removeChild(i);};
i.src = 'http://www.mysite.com';
document.body.appendChild(i);
i.id='frame1';

Now,

document.getElementById('frame1').contentDocument.getElementById('text01').value

Should have given me the value in 'text01', but it doesn't. It doesn't work even inside the iFrame's onload event.
('text01' is a textbox which is on the page inside the iFrame - its name and id are both 'text01')

Is there any other method to get the text in a textbox within an iFrame?

Please help me to correct the code. Thanks in advance.

Convert Text In A Textbox For Password?

Similar Tutorials

Basically what I am looking for is a script that when you click a button, it changes the text in a text box to asterisks, AND also submits the information to the server, so it can be saved. Even if it does not send info to the server, if it can switch it, That would be good too. Can anyone help me with this script?

I am sure that lots of people have seen the Credit Card commercial on T.V. with Emmitt Smith and him putting in his password of "Catch-22" then clicking on a button, and the password automatically changes to asterisks (********) in the textbox.

How is this done? Is it js, ssl or what? If it is a ssl, can someone tell me what kind it would be? I would like to have something like that for a website of mine, where the user can create his password, and see it before he/she confirms it as the password by clicking on the "confirm" button.

I dont like having to enter my password twice to verify it, so I think that this would do the job better for me.

Thanks,

Checking The Text In A Textbox Against A Javascript Array

Similar Tutorials

View Content

Hello,

Can you someone point me to the right script?

I have a text box and would like to see if the value of the input matches the values defined in a JavaScript array.

For example, the JavaScript array will hold five values:

v1 = Tom
v2 = Jerry
v3 = Michael
v4 = Stephanie
v5 = Michelle

If the text box does not equal one of those values, an alert will pop up stating it does not match.

Thanks.

   date_default_timezone_set("Asia/Singapore"); //set the time zone  
$con = mysql_connect('localhost', 'root','');

if (!$con) {
    echo 'failed';
    die();
}
mysql_select_db("mes", $con);
?>

function ini()

// Retrieve the code
var code =document.getElementById ("code_read_box1").value;

}

How To Change A Textbox Value With Javascript Only When The Textbox Is Empty?

Similar Tutorials

View Content

Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be?

Code:

<form name="signup" action="javascript:void(0);" method="post">

<table>
	<tr>
		<td>Date Of Birth:</td>
		<td>
		<input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" />
		<input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" />
		<input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td>
	</tr>
	<tr>
		<td></td>
		<td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td>
	</tr>
</table>
</form>

<script type="text/javascript" language="javascript">
<!--
	document.signup.DOBmonth.value="MM";
	document.signup.DOBday.value="DD";
	document.signup.DOByear.value="YYYY";

function clearDOBmonth() { document.signup.DOBmonth.value="";}
function clearDOBday() { document.signup.DOBday.value="";}
function clearDOByear() { document.signup.DOByear.value="";}
function restoreDOBmonth()
	{
		if ('document.signup.DOBmonth.value = ""')
			{
				document.signup.DOBmonth.value = "MM";
				// alert(document.signup.DOBmonth.value);
			}
	}

//-->
</script>

Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code:

var a = document.form.textbox.value;
a = blue;

does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks!

In my coding, ys, ms, ds represents year starting, month starting, starting day...
ye, me, de represents end...

start,end gives file names in the format of yyyymmdd

now i want to process files from 20100101 to 20100930

means from date is 2010/01/01 and to date is 2010/09/30

if i press submit button the files from 20100101 to 20100930 are processes

here ys=2010 ms=01 ds =01 and ye=2010 me=09 de= 30

For this how do i call these textbox values (from date text box and todate) to another program (java)

Thanks in advance.

Textbox Value From Option Name Or Id

Similar Tutorials

View Content

Hey guys, I recently found a small code in internet which use option value in select tag to insert value in text box, so text box has the exact same value as selected option:

Code:

<form name="theform" onsubmit="CheckForm()">

<select name="myOptions" onchange="document.theform.showValue.value=this.value">


<option name="(some dynamic text)" id="(some dynamic text)" value="I am the first option">I am the first option</option>
<option name="(some dynamic text)" id="(some dynamic text)" value="I am the second option">I am the second option</option>
<option name="(some dynamic text)" id="(some dynamic text)" value="I am the third option">I am the third option</option>
<option name="(some dynamic text)" id=""(some dynamic text)" value="I am the third option">I am the fourth third option</option>

</select>
<input type="text" name="showValue"><br>
</form>

Now what I want is simple and a little different from this one, I want the text box value to be as exact as selected option name or id (doesn't matter which one) which means if an option selected, text box value has to follow that option name or id.

Thanks folks.

I have disabled Ctrl+v, but my customer want to enable ctrl+v for that text-box only. My requirement is after pasting the value it should automatically check for validation.. How to do it?

Hi there,
I have two textboxes and I want some images to be displayed in my textboxes randomly
if randomNumber==1 let textbox1/textbox2 backgroundimage change and if randomnumber==2
let textbox1 backgroundimage change again.
I think I need some fixing in the following lines:
document.getElementById("txtbox1").Attributes.Add("this.style.backgroundImage = 'url(1.jpg)';");

Thanks for any help..

PHP Code:

<script>
setInterval("showimages()",500);
function showimages()
{
var rno=Math.floor(Math.random()*2)+1;
document.getElementById("box1").value=rno;
if(rno==1){

document.getElementById("txtbox1").Attributes.Add("this.style.backgroundImage = 'url(1.jpg)';");
document.getElementById("txtbox2").Attributes.Add("this.style.backgroundImage = 'url(2.jpg)';");
}
if(rno==2){

document.getElementById("txtbox1").Attributes.Add("this.style.backgroundImage = 'url(3.jpg)';");
document.getElementById("txtbox2").Attributes.Add("this.style.backgroundImage = 'url(4.jpg)';");
}

}
</script>
<input type="text" id="txtbox1" style="position:absolute;top:200px;left:200px;height:150px">

Have you tried using your error console (F12 key)?

if(reg.test(email.value) == "") { should be
if(!reg.test(email.value) {

as test returns true or false.

But form validation of the pattern if (document.formname.formfield.value == "") - that is blank or empty- is barely worthy of the name, and virtually useless, as even a single space, an X or a ? will return false, that is pass the validation. A proper name may only contain letters, hyphen, space and apostrophe.
Numeric values, such as zip codes, phone numbers and dates, should be validated as such. Ditto email addresses (as you have done). This topic has been covered many times before in this forum.

The use of with is strongly deprecated and is forbidden in strict mode, and alerts are long obsolete as a way of displaying a message to your users. And so is assigning a name to a form - it is allowed only for the sake of backwards compatibility.

In short - you should rewrite your code to modern standards.

Hi,

I am having a very difficult time trying to get my text box to validate. I successfully validated my first program using prompts but now when I am using a HTML form I cannot get it to work. I have spent hours upon hours trying to get this working, any help would be greatly appreciated.

Code:

<html>
	<head>
	<title></title>
		<script type="text/javascript">
		function validateform()
			{
				var temp = document.forms["inputform"]["temperature"].value
				while ((isNaN(temp)) || (temp == ""))
					{
					alert("Please enter a number");
					return false;
					}
				if (parseFloat(temp) > 35)
						{
						alert("Wow, it's really hot!");
						}
						
					else if (parseFloat(temp) <= 35) && (parseFloat(temp) >= 18))
							{
							alert("It's a comfortable temperature right now");
							}
										
					else if (parseFloat(temp) < 18)
								{
								alert("Brrr, it's a little bit cold for my liking");
								}
					else
						{
						alert("Goodbye, and thanks for using TempReader");
						}		
			}
		</script>
	</head>
	<body> 
	<form name="inputform" method="post" action="">
			<table>
				<tr><td>What Is The Temperature?</td><td><input   type="text" name="temperature"></td></tr>
				<!-- Below is submit button that when pressed validates the form -->
				<tr><td></td><td><input type="submit" value="Submit Details" onclick = validateform()></td></tr>
			</table>
		</form>	
	</body>
</html>

OK, my javascript is not that good. So I need your help!

I need to create a text box that will only work if a certain code is entered. So if 1234 is in the text box and submit is clicked, then it will take you to the site. IF not then it will print "Please enter correct code" next to the submit button.

Here is what I have so far:

<input name="txtBox" type="text"/>

<input name="btnButton" type="button" value="Submit" onclick="return checkValue()" />

<script type="text/JavaScript">
function checkValue()
{
var secretcode = document.getElementById("txtBox");

if (secretcode == "1234")
{
document.location.href = 'secret.html';
}
}
</script>

Thank you for your help!
