JavaScript - Variable To Textbox Help.

Hi,

I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it.

I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page.

Thanks for all the help

P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side...

Hi,

i got a textbox with a submit button but when submit button is clicked it works but it reloads the page.

is possible to submit without reload the page?

thanks

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.

Hi,

I have a text-box where you enter the phone nos. On key-press, i have written a validation code to enter only nos and "-". 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?

Thanks...

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!

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)';");
}

}

hi, I would to validate a textbox, and limit it to 3alphabets and 3 numbers.
That is after the user have input 3 alphabets, he can only enter 3 numbers and nothing more. Can someone help me out?

I would like to type something into my textbox and then press ENTER, it will execute a function.

I tried onFocus, onChange and onBlur but it doesn't do what I want it to.

Here's an example I use for onChange.

Code:

Application: <input type="text" onchange="execProg(0);">

Any comments or suggestions is greatly

My code is not validating the textboxes..if someone could help me figure this out.
Thank you

<script type="text/javascript">
function validate() {
with (document.form1) {
var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
var alertMessage = "The following fields\nare REQUIRED:\n\n";
if (realname.value == "") {
alertMessage += "Name\n" }
if(reg.test(email.value) == "") {
alertMessage += "Email\n" }
if (phone.value == "") {
alertMessage += "Phone\n" }
if (security_code.value == "") {
alertMessage += "Security Code\n" }
if (alertMessage != "The following fields\nare REQUIRED:\n\n") {
alert(alertMessage);
return (false);}

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.

Hello

How am I able to add a a cross to the right of a textbox which once click it clears the text from the textbox, sort of like the way Google do it, I have been trying to do this for ages now and can't seem to find a way to do it.

Any help welcome, thank you.

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>

how would you make a function that cheks if any text is in a text box.
