JavaScript - Need Some Help For Validation Asap
Hi i need some help for my validation, it does not have pop up for the words that match with bw and my codes i need to check whether is it a ew. if it is a ew even if it contain bw it will return true. hope there is someone can help me thanks alot in advance
my codes are this var sw = theForm.fmessage.value.split(" "); var tw = theForm.fmessage.length; var i=0; for (i=0;i<tw;i++){ <?php while($row1 = mysql_fetch_assoc($result1)){?> var ew = "<?php echo $row1['ew'] ; ?>"; var bw = "<?php echo $row1['bw'] ; ?>"; if (sw[i].match(bw)) { alert(bw); err = bw; } <?php }?> } if (err != "") { alert("Badword(s) found : " + err); theForm.fmessage.focus(); return false; } Similar TutorialsHey, basically I have my assignment due in 2 and a half hours and I cannot work out how to validate a email address. What am I doing wrong? Been on the net for a couple of hours lurking to find some answers but now I am even more lost. Bit of information: Basically I need to work out how many tables are needed for a class room depending on the desktops and laptops used and how many roils of coils are needed blah blah blah. Then comes the tricky part (for me anyways) asking the user to confirm or cancel the order everything works up to confirming the quote and then validating the email address, canceling the confirm button works so I'm assuming it's just the validating that I have destroyed. Any help would be awesome, assignment is due very soon and no sections of code are helping me on the net. Code: function confirmquote()
{
var answer=confirm("Do you want to recieve a quote?");
if (answer==true)
{
var emailID=window.prompt("Please enter a VALID email address or type quit to exit");
}
else
{
alert("Quote has been rejected sir, please refreash to start order agian.");
}
}
}
function CheckEmail()
{
emailID = document.f1.Email.value
AtPos = emailID.indexOf("@")
StopPos = emailID.lastIndexOf(".")
Message = ""
if (emailID == "")
{
Message = "Not a valid Email address" + "\n"
}
if (AtPos == -1 || StopPos == -1) {
Message = "Not a valid email address"
}
if (StopPos < AtPos) {
Message = "Not a valid email address"
}
if (StopPos - AtPos == 1) {
Message = "Not a valid email address"
}
return Message
}
(ALL IN THE HEADER TAG) Code: var worknowplease = confirmquote(); var emailID=checkemail(); (Last few lines of code before [/body]) I have no idea what the validate email is trying to do in the coding, but I'm still very freash on JS. Thanks you for reading and if you can share any possible solutions to my problems. Thanks agian. HI lads im new javascript learner ,i have been trying to find out what is wrong with my coding it never worked and i cant see the mistake code : var lotto=[]; var myLotto=[]; function isFilled(field) { while (field==null || field.length == 0 || (!isnotNumeric(field))) { alert("The input was not a valid number"); field = parseInt(prompt("Enter your favourite number, please","")); } return field; } function isnotNumeric(num) { if (isNaN(num) || num < 1 || num > 45) { return false; } else { return true; } } function getData(){ var i = 0; while (i<7) { number = Math.floor(Math.ramdom()*45+1); if (!numberFound(lotto,number)) { lotto [i] = number; alert(lotto[i]); i++; } } } function numberFound(testArray,myNumber) { for (x = 0; x<testArray.length;x++) { if (myNumber == testArray[x]) return true; } return false; } function getMyNumbers() { var number = i; for (i = 0; i<5; i++) { myNumbers = parseInt(prompt("Enter in number " + number + ":","")); isFilled(); number=number+1; } } thank you very much i really dont understand this java problem, i did all i could and i still dont get it plz help me. Its my practice test for tomorrow and i dont get this. In video games it is often required to be able to determine if two balls have collided. Create a program which accepts the radius and the center (x,y) of each ball and states whether the two balls have collided. Hint: Draw and label all the known information for situations (2) when the balls have collided and when they have not collided. <HTML> <HEAD> <TITLE></TITLE> <SCRIPT LANGUAGE="JAVASCRIPT"><!--Hide from old browsers var msgSpace = "--- ---" var beginPos = 0 function doMort() { document.MortCalc.Price.value=" " document.MortCalc.Shares.value=" " document.MortCalc.Dividend.value=" " document.MortCalc.Time.value=" " document.MortCalc.Price.focus() } function Calc(myform) { var mortAmount=document.MortCalc.Price.value var mortAmount=parseInt(mortAmount,10) if (isNaN(mortAmount)) { alert() document.MortCalc.Price.value=" " document.MortCalc.Price.focus() } else { var mortShares=document.MortCalc.Shares.value var mortShares=parseFloat(mortShares) if (isNaN(mortShares)) { alert() document.MortCalc.Shares.value=" " document.MortCalc.Shares.focus() } else { var mortDividend=document.MortCalc.Dividend.value var mortDividend=parseInt(mortDividend,10) if (isNaN(mortDividend)) { alert(") document.MortCalc.Dividend.value=" " document.MortCalc.Dividend.focus() } } } document.MortCalc.Time.value=monthly(mortPrice,mortShares,mortDividend) document.MortCalc.Time.value=dollarFormat(document.MortCalc.Time.value) } function Price(mortPrice,mortShares) { var Price * Shares } function dollarFormat(valuein) { var formatStr="" var Outdollars="" var decipos=valuein.indexOf(".") if (decipos==-1) decipos=valuein.length var dollars=valuein.substring(0,decipos) var dollen=dollars.length if (dollen>3) { while (dollen>0) { tDollars=dollars.substring(dollen-3,dollen) if (tDollars.length==3) { Outdollars=","+tDollars+Outdollars dollen=dollen-3 } else { Outdollars=tDollars+Outdollars dollen=0 } } if (Outdollars.substring(0,1)==",") dollars=Outdollars.substring(1,Outdollars.length) else dollars=Outdollars } var cents=valuein.substring(decipos+1,decipos+3) if (cents=="") cents="00" var formatStr="$"+dollars+"."+cents return formatStr } open("Notice.htm","noticeWin","WIDTH=400,HEIGHT=220") this is what i have so far but im having trouble adding an accessor method for answer which i have called getAnswer public class Question { private String text; private String answer; private String getAnswer; /** * Constructs a question with empty question and answer. */ public Question() { text = ""; answer = ""; } /** * Sets the question text. * @param questionText the text of this question */ public void setText(String questionText) { text = questionText; } /** * Sets the answer for this question. * @param correctResponse the answer */ public void setAnswer(String correctResponse) { answer = correctResponse; } public String getAnswer(){ return answer; } /** * Checks a given response for correctness. * @param response the response to check * @return true if the response was correct, false otherwise */ public boolean checkAnswer(String response) { return response.equals(answer); } /** * Displays this question. */ public void display() { System.out.println(text); } } (edit) i've fixed it. thanks
hey guys can u please help me with this question.. i've lost ma book and its too late to buy another one.. so some body please help me! this is the question: Kathryn bought 600 shares of stock at a price of $21.77 per share. She must pay her stockbroker a 2 percent commission for the transaction. Write a program that calculates and displays the following: The number of shares purchased The price per share The amount paid for the stock alone (without the commission) (number of shares x share price) The amount of the commission (amount paid for the stock x the commission percent) The total amount paid (for the stock plus the commission) (amount paid for the stock + the amount of the commission) The program should neatly display a text label along with the value. For example: Shares purchased: 600 The program must perform the calculations. It is not acceptable to perform the calculations on a calculator and just use the program to display the results. I should be able to modify the numbers in the program and have it correctly compute the result. Hi, i need to make my alert box stand out a bit more i have looked everywhere but can't find anything! i was looking to do stuff like Bold, Italics, Underline, Fonts, Sizes, Borders, Backgrounds maybe something that flashed! i'm not asking you to do it for me just tell me how and were to put the different codes! and ASAP please as it is in for Thursday!! :S thanks in advance :D Hey all. I have a simple validation I need to do. I need to just make sure that a Checkbox is checked, and that a Text field has content. Sounds simple but I cannot find any thing that has a check and a text field. Here what I have. Can I modify this script to do this? A Checkbox MUST be checked and Text field MUST be filled out. This currently does the text field fine, but no Checkbox obviously. How can I add a checkbox validation to this? Thats it. Any help is appreciated. Code: <script type="text/javascript">
var textFields = ["digsig"];
function validateForm( )
{
var oops = ""; // must initialize this!
var form = document.sig;
for ( var t = 0; t < textFields.length; ++t )
{
var field = form[textFields[t]];
var value = field.value.replace(/^\s+/,"").replace(/\s+$/,""); // trim the input
if ( value.length < 1 )
{
oops += "You MUST enter your Digital Signature";
}
}
if ( oops != "" )
{
alert("ERROR:" + oops);
return false;
}
}
}
</script>
Hello all, new here Seems like a very nice place to be apart of. I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it. The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem. I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs. <problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again. Any pointers in the right direction or solutions to my problem would be greatly appreciated. Thanks! Hopefully it is not to hard huh If there is anything anyone needs, the code pasted here, or anything else please let me know. Thanks again! Hello, I dont know if I am going about this the right way, but.. I am trying to validate an email address. If the email is a valid looking email address, it will render the submit button disabled to prevent dupe's while the rest of the script processes. The email validation portion works, but, the part where it renders the form submit button disabled does not: <script type="text/javascript"> function validate_email(field,alerttxt) { with (field) { apos=value.indexOf("@"); dotpos=value.lastIndexOf("."); if (apos<1||dotpos-apos<2) {alert(alerttxt);return false;} else {return true; submit.disabled = true;} } } function validate_form(thisform) { with (thisform) { if (validate_email(email,"Please enter a valid email address.")==false) {email.focus();return false;} } } </script> Any guidance or help would be apreciated.

i need on submit to validate if user select values from 3 radio groups and insert the proper data to text box. if not i want to return the proper alerts in text box also i want when lose focus to validate so i put this Code: onblur="JavaScript:alert('You must insert a Bank Code')"
it's ok? Thanks in Advance I keep getting validation errors for using && as and. I've read to put "&" in place of it, but whenever I do this, the code stops working. I've tried seperate parenths, and still confused. anyone help to make this work and validate at the same time? if (first=="" && last=="") first = last = "Unknown"; if (first == '') document.writeln(last); else if (last == '') document.writeln(first); else document.writeln (last + ", " + first); Hey. Could someone point me in the direction of why this is not working, it worked in my last program, but not since I have changed things. I have a standard html form Code: <form method="POST" onsubmit="return validate_form(this)" action="anniversaryPreview.php">
<p class="demo5">Senders Name<a class="textFields2">
<input type="text" name="sender" value="e.g. Love from Nick" size="30" maxlength="35" /></a></p>
<p class="btn2" >
<input type="submit" value="Preview"></p>
</form>
And this should call up return validate_form(this) before bringing up the php page. Now the validator is just Code: function validate_required(field, alerttxt) {
if (field.value == null || field.value == "") {
alert(alerttxt);
return false;
}
else {
return true;
}
}
function validate_form(thisform) {
if (validate_required(thisform.name,"Please specify the receivers name.")==false) {
thisform.name.focus();
return false;
}
if (validate_required(thisform.sender,"Please specify the sender's name.")==false) {
thisform.sender.focus();
return false;
}
}
(This is not in the html file, but its own seperate file) I cant see if I have made any mistakes with the variables names or something, or what I am doing wrong. Dont get any errors, just nothing happens if I leave my forms fields blank. Anyone have an idea of whats going on here? cheers In my project i have a from which have several fields. The form is <form name="reg" action="payment.jsp" method="post"> ----------- <tr> <td>First name:</td> <td><input type="text" name="firstname"/></td></tr> -------------------------- <input type="submit" value="Next" onclick="fun()" /> ------------ </form> Then to validate the fields i have used JavaScript.They are validating rightly using a alert box. But when i am pressing ok of the alert box the control is passing to the page i have written in action of the form.I want when i will press ok it should come back to the same page.Only if all fields are then it should go to the page refereed in action. Can anyone help me? The JavaScript code is <script type="text/javascript"> function fun() { var x=document.forms["reg"]["firstname"].value; if (x==null || x=="") { alert("First name must be filled out"); } Hi All, I have a java script invoked within an ANT template. This java script as of now converts a text file to xml file. Now, how would I do the schema validation of that XML file against an XSD in the javascript? Saw many examples online but they were using MSXML or java classes Would be glad to have any sort of suggestions.. Thanks Hi, got my form here Code: <form method="POST" onsubmit="return validateFormOnSubmit1(this)" action="sendEmail.php">
<p class="demo2">Receivers E-mail<a class="textFields">
<input type="text" name="receiver" size="30" maxlength="35" /></a></p>
<p class="demo2">Senders E-mail<a class="textFields2">
<input type="text" name="sender" size="30" maxlength="35" /></a></p>
<p class="btn" >
<input name="Submit" type="submit" value="Send"/></p>
</form>
And that should call up this Code: function validateFormOnSubmit1(theForm) {
var reason = "";
reason += validateEmail1(theForm.receiver);
reason += validateEmail1(theForm.sender);
if (reason != "") {
alert("Some fields need correction:\n" + reason);
return false;
}
return true;
}
function trim(s)
{
return s.replace(/^\s+|\s+$/, '');
}
function validateEmail1(fld) {
var error="";
var tfld = trim(fld.value); // value of field with whitespace trimmed off
var emailFilter = /^[^@]+@[^@.]+\.[^@]*\w\w$/ ;
var illegalChars= /[\(\)\<\>\,\;\:\\\"\[\]]/ ;
if (fld.value == "") {
fld.style.background = 'Yellow';
error = "You didn't enter an email address.\n";
} else if (!emailFilter.test(tfld)) { //test email for illegal characters
fld.style.background = 'Yellow';
error = "Please enter a valid email address.\n";
} else if (fld.value.match(illegalChars)) {
fld.style.background = 'Yellow';
error = "The email address contains illegal characters.\n";
} else if (fld.value.length == 0) {
fld.style.background = 'Yellow';
error = "The required field has not been filled in.\n"
} else {
fld.style.background = 'White';
}
return error;
}
For some reason though the validation is not working. Is there anything obvious I am doing wrong? cheers 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... I have this php validation string
Code: $urlregex = "^(https?|ftp)\:\/\/([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?[a-z0-9+\$_-]+(\.[a-z0-9+\$_-]+)*(\:[0-9]{2,5})?(\/([a-z0-9+\$_-]\.?)+)*\/?(\?[a-z+&\$_.-][a-z0-9;:@/&%=+\$_.-]*)?(#[a-z_.-][a-z0-9+\$_.-]*)?\$";
and i want it to convert into javascript. please help |
