Hi!

I want to be able to have a phone and email radio button group. The email textbox also has a RegularExpressionValidator If the phone item is selected then I want the validation to be enabled on the phone text box making it mandatory while the email text box isn't, and if they choose the email as the contact it will be reversed. I want to be able to do this without having to do a postback. I already have the logic on the code behind and the enquiry object. also I am fairly new to javascript so I have been using mostly jQuery as easier to implement Hi.. I have form and i want to input data using barcode and it will display on textbox and after input on the first textbox the focus will go to next textbox untill it will go on the last textbox and on the last textbox it will automatically save the data's on the database. How is it possible? here is my sample code: Code: <?php
error_reporting(0);
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);

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! I have a bunch of checkboxes like below that the user can check some or all and click the button and see the values of all the selected checkboxes. How can I do that? Code: <script>
function alertValues(){
}
</script>
<input type="checkbox" class ="normal2" value="131971" name="list[]" >
<input type="checkbox" class ="normal2" value="131973" name="list[]" >
<input type="checkbox" class ="normal2" value="131975" name="list[]" >
<input type="checkbox" class ="normal2" value="131977" name="list[]" >
<input type="button" onClick="alertValues()"
Hi, What's a good way/ideal data structure to achieve this? The objective of the code/function is to map user-inputted strings into a pair of specific, hard-coded strings. For example, say the user types "firefox" or "ff", or "fx". The output would be the pair ["browser", "mozilla"], for example. I'm currently using a multidimensional array, but it feels inefficient and I'm having trouble mapping an arbitrary number of inputs into 2 outputs. Code: var strings = [ ["input1", "output1a"],
["input2", "output1a"],
["input3", "output1a"],
["input1", "output1b"],
["input2", "output1b"],
["input3", "output1b"]
];
How should I map the elements ["input1", "input2", "input3"] => ["output1a", "output1b"] ? Another method I used previously was a massive switch statement. This fulfills my needs, but I'm not sure about the efficiency (though if I remember correctly, switch statements become more efficient as size grows, since it uses a hash table?). Code: switch (input) {
case "ff": case "firefox": case "fx" : case "ffox":
return ["browser", "mozilla"];
case "ie": case "internet explorer":
return ["browser", "microsoft"];
...
}
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 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 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>
