Thanks in advance. Similar TutorialsHello, i have coded this page: http://www.advance2000.net/system/ad...rchasepeso.php click on the "ADD ITEM" button TWICE. now you have created two rows of textboxes. next, enter the letter "M" on the description textbox on the second row. this would then initialize an autocomplete function... you will see two words "memory" and "motherboard" try clicking one of these.. after clicking, i guess you will notice the error in my program. the clicked value (for example "memory") would be sent in the FIRST ROW TEXTBOX instead of the second.... can anyone help me? Here is the Code of the said Dynamic Textbox: Code: <script language ="javascript">
row_no=0;
function addRow(tbl,row){
row_no++;
if (row_no<=200){
if (row_no<=200){
if (row_no>=100){
var textbox = '<input type="text" id="item[]" value='+row_no+' size = "2" maxlength= "99" name="item[]>"';}
if (row_no<100){
var textbox = '<input type="text" id="item[]" value='+row_no+' size = "2" maxlength= "99" name="item[]">';}
var textbox2 = '<input type="text" id="stockcode[]" size = "20" maxlength= "100" name="stockcode[]">';
var textbox3 = '<input type="text" autocomplete="off" id="description" size = "95" maxlength= "100" name="description" onkeyup="lookup(this.value);" onChange="fill();"><div class="suggestionsBox" id="suggestions" style="display: none;"><img src="upArrow.png" style="position: relative; top: -12px; left: 30px;" alt="upArrow" /><div class="suggestionList" id="autoSuggestionsList"></div>';
var textbox4 = '<input type="text" id="qty'+row_no+'" size = "6" maxlength= "100" onChange="Sum()" name="qty[]">';
var textbox5 = '<input type="text" id="price'+row_no+'" size = "15" maxlength= "100" onChange="Sum()" name="price[]">';
var textbox6 = '<input type="text" id="subtotal'+row_no+'" size = "15" maxlength= "101" onChange="Grand()" name="subtotal[]" readonly>';
var tbl = document.getElementById(tbl);
var rowIndex = document.getElementById(row).value;
var newRow = tbl.insertRow(row_no);
var newCell = newRow.insertCell(0);
newCell.innerHTML = textbox;
var newCell = newRow.insertCell(1);
newCell.innerHTML = textbox2;
var newCell = newRow.insertCell(2);
newCell.innerHTML = textbox3;
var newCell = newRow.insertCell(3);
newCell.innerHTML = textbox4;
var newCell = newRow.insertCell(4);
newCell.innerHTML = textbox5;
var newCell = newRow.insertCell(5);
newCell.innerHTML = textbox6;
}
if (row_no>200){
alert ("Too Many Items. Limit of 20.");
}
}
}
</script>
The VAR TEXTBOX 3 would create the said "description textbox" that is also the textbox that calls the "Fill()" and the Lookup() function of the autocomplete HERE, we have the said functions: Code: function lookup(description) {
if(description.length == 0) {
// Hide the suggestion box.
$('#suggestions').hide();
} else {
$.post("rpc.php", {queryString: ""+description+""}, function(data){
if(data.length >0) {
$('#suggestions').show();
$('#autoSuggestionsList').html(data);
}
});
}
} // lookup
function fill(thisValue) {
$('#description').val(thisValue);
setTimeout("$('#suggestions').hide();", 200);
}

If not then is it possible to variables between javascript and vbscript, or call vbscript function using javascript. a sample code will be much aprreciated thanks for your time! J I have a javascript that loads images on the page based on the date you select from a drop down menu. So the images are displayed dynamically, however they are numbered 1 through 20. Is there a way I can add a title tag to the images that will display on mouseover? Here's the page I am working on. I want to add title tags to the six images on the right side of the page. They change based on the date selected. webpage Thanks. From the these form fields I want to be able to create an array in Javascript containing the same 'codes' that feature between the option tags (not the value="X") Code: <select name="options-1" id="options-1"> <option value="">Select an option</option> <option value="1">KA-WH</option> <option value="2">KA-BK</option> <option value="3">KA-GN</option> </select> <select name="options-2" id="options-2"> <option value="">Select an option</option> <option value="4">BADGE-1</option> <option value="5">BADGE-2</option> <option value="6">BADGE-3</option> </select> <select name="options-3" id="options-3"> <option value="">Select an option</option> <option value="7">E-WH</option> <option value="8">E-GD</option> <option value="9">E-BK</option> </select> for example, from the above, I want a JS array for 'option-1' that contains KA-WH, KA-BK and KA-GN; plus an array for 'option-2' that contains BADGE-1, BADGE-2 and BADGE-3. The above form fields will be created dynamically, may contain more or fewer items. I then want to use the JS arrays to pull in images of which filenames match the 'code' in the array. Hi, I have a webpage that needs to play a different mp3 file each day of the month from a javascript controlled html5 audio tag. I have the files on the server, and each filename ends with a number 1 through 31 (filename30.mp3, filename31.mp3 etc.). Because javascript can easily give me the date for each day, how can I insert this date like... src="filename[date].mp3" within the audio tag? Inserting a date with javascript is easy for text on a webpage, but I am not sure how to produce this in html code that is yet to be rendered. Here is the relevant portion of the html that I need the date to be inserted into: Code: <audio src="filename[need date here].mp3" id="audio"></audio> <input type="range" step="any" id="seekbar"></input> Many thanks for any help!

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 All, i know how to create a dynamic form or DIv ..but what i do not know is how to create a dynamic form/ or div into a previous dynamic one.. i need basically to see 5 dynamic forms / DIV in cascade where each one trigger the one coming after.. For what i need that : i have my user inserting information on the level 1. let say Copagny info 2- then he will be asked if he wants to add a sub level information ( subform) for that compagny or even many subforms at the same level .. and so on... 3- those sub level ( subforms ) can also call their respective subforms.. Any idea how to design this ? thanks I have made a script where you can add extra fields, and next to the row is a span that automatically displays the outcome from a calculation of three fields in that row. i.e. Q x (B - A) = total. Here is the bit that does the calculation: Code: function advCalc(selected) {
var result = Number(document.formmain.elements["quantity"+selected].value) * (Number(document.formmain.elements["provideamount"+selected].value) - Number(document.formmain.elements["supplyamount"+selected].value)) ;
result = result.toFixed(2) ;
result = addCommas(result) ;
document.getElementById("total"+selected).innerHTML = result ;
}
The bit that adds a new row of fields is: Code: function addPart(divName){
var newdiv = document.createElement('div') ;
newdiv.setAttribute('id', 'partrow' + counter) ;
newdiv.setAttribute('style', 'clear:both;') ;
newdiv.innerHTML = "<div style='float:left;width:40px;text-align:center;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc('" + counter + "')\" id=' quantity " + counter + "' type='text' value='1' size='1'/>\r</div>\r<div style='float:left;width:100px;text-align:left;margin:5px 0px 0px 0px;'>\r<input id='manufacturer" + counter + "'type='text' value='' size='9'/>\r</div>\r<div style='float:left;width:95px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='partnumber" + counter + "'type='text' value='' size='9'/>\r</div>\r<div style='float:left;width:80px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='supplier" + counter + "'type='text' value='' size='4'/>\r</div>\r<div style='float:left;width:100px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='type" + counter + "'type='text' value='' size='6'/>\r</div>\r<div style='float:left;width:85px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='deliverytime" + counter + "'type='text' value='' size='13'/>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 0px 0px 45px;'>\r<select id='supplyCurrency" + counter + "'>\r<option value='pound' selected='selected'>£</option><option value='dol'>$</option><option value='euro'>€</option></select>\r</div>\r<div style='float:left;width:15px;text-align:left;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc(\'" + counter + "\')\" id=' supplyamount " + counter + "'type='text' value='' size='3'/>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 0px 0px 45px;'>\r<select name='provideCurrency" + counter + "'><option value='pound' selected='selected'>£</option><option value='dol'>$</option><option value='euro'>€</option></select>\r</div>\r<div style='float:left;width:15px;text-align:left;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc(\'" + counter + "\') id=' provideamount " + counter + "' type='text' value='' size='3'/>\r</div>\r<div style='float:left;width:20px;text-align:left;margin:5px 0px 0px 45px;'>\r<strong>£</strong>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 5px 0px 0px;'><span id=' total " + counter + "'></span></div> \r" ;
document.getElementById(divName).appendChild(newdiv) ;
counter++ ;
}
The problem I am having is that it works fine for the first row which is hardcoded as e.g. id="provideamount0" etc. It isn't working for any other fields added but I can't see what is wrong 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 how can i pass the var to textboxes Code:
var win = 0;
var loss = 0;
var draw = 0;
if (c == u) {
draw++;
return "It's a draw";
}
else if ((c == "Fire") && (u == "Air")) {
loss++;
return "You Lose, Fire beats Air!";
}
else if ((c == "Fire") && (u == "Earth")) {
draw++;
return "It's a draw!";
}
else if ((c == "Fire") && (u == "Water")) {
win++;
return "You Win, Fire is beaten by Water!";
}
<tr><td><input type=text size=5 name=w ></td><td>win</td></tr>
<tr><td><input type=text size=5 name=l></td><td>loss</td></tr>
<tr><td><input type=text size=5 name=d></td><td>draw</td></tr>
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>
<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>

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. 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. Is it easy to add a smiley script to a guestbook ? I want a few faces like the ones on this page.. I hope there is some simple way to do this - google didnt really help me..

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 "-".
