I have a page where a user can enter info into a text box named (usertext). Below the box I have a link that takes the user to another page. This page is just a test page for proof of concept. I am wondering if there is a way that I can dynamically populate a variable located within the url of my link. The info that will populate the variable will be whatever the user types into the text box. For example my link will be <a href="nextpage.cfm?textvariable='#usertext#'> So when the user clicks this link, it goes to the next page already populated by the value of the info the user typed into the text box. I am thinking javascript will be involved, but I am not really sure. I am using coldfusion 8. Hi! I am quite new to the world of JavaScript as I have done basic corse for it... and I have learnt that best way to understand it is to play around with it... but now I am stuck with on of the problem!! Problem: How can we assign text box input values by user to a variable and display that variable back on another element of the same HTML document(dynamically)... Conditions: The value has to be stored as a JavaScript variable only. No server-side script is to be used and has to be done locally. Please help! Basically I am being restricted by a third party program that manages my email list. When a person signs up for my website it first adds them to my external email list and then to my MySQL database. In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work. So what I am trying to do is take what is outputted by this display button and store it in a javascript variable. Then transfer this variable to a form which will auto submit and start the PHP registration. I need help pulling the output of the script, right now I can either get an undefined or the entire HTML code. Is there another option? Here is my code: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd"

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! 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 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! 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);} return (true) } } </script> <form action="formmail.php" method="post" enctype="multipart/form-data" name="form1" id="form1" onsubmit="return validate()" > Reply With Quote 01-31-2015, 09:12 AM #2 Philip M View Profile View Forum Posts Supreme Master coder! Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts 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 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? 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>

<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");
}
}

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