JavaScript - Input Field Being Affected By A Function
Below is my previous code I had working in the manner it would change the price, sub_total, tax, sh, total, and total_paid input fields to 0. There are two problems with this...
1. When it outputs to the input fields, the value displays as 0 instead of 0.00. 2. I need to have it only react when the value typed into the input field "trees_sold" is "0". If any higher, I would like it to ignore the statement. Code: <!-- Comp all prices to zero value -->
<SCRIPT LANGUAGE="JavaScript">
var trees_sold = 0.00;
function InitSaveVariables(form) {
price = form.price.value;
sub_total = form.sub_total.value;
tax = form.tax.value;
sh = form.sh.value;
total = form.total.value;
total_paid = form.total_paid.value;
}
function CompPrices(form) {
if (trees_sold == 0.00) {
InitSaveVariables(form);
form.price.value = 0.00;
form.sub_total.value = 0.00;
form.tax.value = 0.00;
form.sh.value = 0.00;
form.total.value = 0.00;
form.total_paid.value = 0.00;
}
}
</script>
Code: <input name="trees_sold" id="trees_sold" size="15" onkeyup="javascript:CompPrices(this.form);" maxlength="15" /> Below is my current code I'm working with that I can't seem to get to function properly. I've modified the first two lines of code here, and am attempting to pull any data that is typed in and automatically take into consideration if it is a "0" value, it reacts as my code below says "if (trees_sold == 0.00)" and if anything else, it will not do anything. This is not working unfortunately. Code: <!-- Comp all prices to zero value -->
<SCRIPT LANGUAGE="JavaScript">
form.trees_sold.value = "";
trees_sold = form.trees_sold.value;
function InitSaveVariables(form) {
price = form.price.value;
sub_total = form.sub_total.value;
tax = form.tax.value;
sh = form.sh.value;
total = form.total.value;
total_paid = form.total_paid.value;
}
function CompPrices(form) {
if (trees_sold == 0.00) {
InitSaveVariables(form);
form.price.value = 0.00;
form.sub_total.value = 0.00;
form.tax.value = 0.00;
form.sh.value = 0.00;
form.total.value = 0.00;
form.total_paid.value = 0.00;
}
}
</script>
Code: <input name="trees_sold" id="trees_sold" size="15" onkeyup="javascript:CompPrices(this.form);" maxlength="15" /> Anyone have any ideas? Thank you.

This gives me a "Uncaught ReferenceError: clearInputField is not defined" error and I'm not sure why...? I'm building a template editor and need some help changing some of the variables. Part 1. Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s I need to be able to fill out two fields to change DEALERNAME and 00/00/00. I found a way to do this but it required the output to be in a field. I need it the output to look no different than before. Part 2. I'm using this to change some text via radio button but I would like an option to select how many details are there is the first place. Say they only want 1 or 2 details and not 3. Head Code: <script language="javascript" type="text/javascript">

When I want to submit the form I don't get any users passed along, course they are not "selected". I have then read around on the net and I need to create an elemet with a hidden input field where all the randomly selected users is inserted to with comma separation, but dont know how?!?! This is what I got: Code: function randomusers(){
var given = 3, used = {}, randnum, opts = $('#select1 option'), olen = opts.length;
function ran() { // generate a unique random number
randnum = Math.floor(Math.random() * olen);
return used['u'+randnum] ? ran() : randnum;
}
for (var i = 0; i < given; i++) { // get the correct quantity of randoms
used['u'+ran()] = true;
}
opts.filter(function(index) { // remove all options that are not one of the randoms
return !!used['u'+index];
}).appendTo('#select2');
}
I have tryied to insert this: appendTo('#select2' + '<input type="hidden" name="test[]" value="" />'); but that didn't seem right... Please help :-) i was wondering what event would clear an input field that has a value in it... so a user can type their own value.... any examples?

Hi all, I have a complicated (well to me it is!) problem with a form I am creating for my site. The form has three sections with the ability to add another field unlimited times. There is one for adding ingredients, one for equipment and one for steps The name and id does increment on all 3 however the problem is they seem to all be using the same count, by this I mean that if I add 2 steps (which brings the count to 3) and then add an ingredient, the ingredient id goes to ingredient4 - obviously because it is taking the count that step has set. I am no javascript guru, I am more a designer so I'm really struggling, Ive been working on this one for days.. There is also another problem in that if I create say 3 steps bringing the count up to step4 and then remove the second step, I cant see how I can bring the other steps after step2 count down by one, at the moment step4 and step3 are staying as step3 and step4 but because step2 was removed they should drop down to becoming step2 and step3. My php that inserts the data into my db isnt working because the ids keep getting messed up I have a demo URL up on ajburchell.com/form.html If anyone can help me with this I will be extremely grateful Thank you in advance Hi! I want to insert flash player on my page, that user can change flv source. But I dont know how to make input field that change flv source. I tried to insert input field and button but dont know how to make it working, please help me Here is my flvplayer embed code: <script type="text/javascript" src="http://flvplayer.com/free-flv-player/flvplayer/swfobject/swfobject.js"></script> <div id="embed_player"> <h1>Please Upgrade Your Flash Player</h1> <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p> </div> <script type="text/javascript"> var flashvars = { flvpFolderLocation: "http://flvplayer.com/free-flv-player/flvplayer/", flvpVideoSource: "http://flvplayer.com/media/audi_tdi_commercial.mp4", flvpWidth: "640", flvpHeight: "375", flvpInitVolume: "50", flvpTurnOnCorners: "true", flvpBgColor: "#FFFFFF" }; var params = { bgcolor: "#FFFFFF", menu: "true", allowfullscreen: "true" }; swfobject.embedSWF("http://flvplayer.com/free-flv-player/FlvPlayer.swf", "embed_player", "640", "375", "9.0.0", "http://flvplayer.com/free-flv-player/flvplayer/swfobject/expressInstall.swf", flashvars, params); </script> I searched the forum for an answer to this question, but found nothing that was able to answer my question. I have a form and I need to validate a field against three rules: 1) The field need to be between 6 and 12 characters 2) It can only have letters, numbers, and the underscore 3) It cannot contain a space or other special characters I want the validate to happen in real-time. I have the first rule working great. Here is the code for that: Code: var username = document.getElementById('registerUsername');
if((username.value.length < 6) || (username.value.length > 12))
{
document.getElementById('usernameValidate').innerHTML="Incorrect.";
}else{
document.getElementById('usernameValidate').innerHTML="Correct.";
}
How would I be able to incorporate checking for rules 2 and 3? I've not really an idea how to do this. I know how to do it in PHP, but I need it dynamic <input type="checkbox" name="facebook" value="1" /> if($_POST['facebook'] == 1) echo "<input type='text' name='facebook_url' />"; Could someone tell me how I should do this. Thanks. Hi, my first question on this forum is I hope a simple one. I have an input text field that I would like to have either the user fill out but also I would like to be able to fill it with text, which I can do, via javascript or a variable which I don't seem to be able to manage. I have tried lots of options, converting to a string first and much more but it will not work, maybe it is a syntax error or maybe I am just doing it plain wrong. I think it should be simple but I have only been using javascript for a few weeks so who knows, hopefully one of you! Here is my code for displaying a variable which does not work: Code: <html>
<head>
<script type="text/javascript">
function myfunction()
var mynumber = 101;
document.getElementById("myinput").value = mynumber;
</script>
</head>
<body>
<p id="demo">Web Page 1</p>
<button type="button" onclick="myfunction()">JS</button>
<input type="text" value="00000000" id="myinput">
</body>
</html>
I would be very grateful for any help. Thanks Simon Hi, I am trying to write some code that will test if a user enters a non-numeric character in an input text field, and if so, replaces it with a '0' Code:
<script type="text/javascript">
function IsNumVal (){
for (J=1; J<=3; J++){
if (isNaN(Number(document.getElementById('Intext' + J).value))){
document.getElementById('Intext' + J).value = 0;
}
}
}
</script>
<Body>
<table border="1" cellspacing="1" id = "Numbers">
<tr id="RowNum1">
<td ><input type="text" size = "5" name="Intext1" id="Intext1" value = "3"
onkeyup="IsNumVal()" /></td>
</tr>
<tr id="RowNum2">
<td><input type="text" size = "5" name="Intext2" id="Intext2" value = "9"
onkeyup="IsNumVal()" /></td>
</tr>
<tr id="RowNum3">
<td><input type="text" size = "5" name="Intext3" id="Intext3" value = "18"
onkeyup="IsNumVal()" /></td>
</tr>
</table>
</Body>
document.getElementById('Intext' + J).value = 0; doesn't work document.Schedule.'Intext' + J.value = 0; doesn't work document.Schedule.Intext2.value = 0; works, but I need to test each text field while looping, so I can't "hard code" the ID. Suggestions? I have an existing form with radio buttons and a text input field: <input type="radio" name="recurringEnd" value="yes"> End after <input type="text" name="numberOccurrences" size="1"> occurrences <input type="radio" name="recurringEnd" value="date"> End on <input type="text" name="endDate" size="8"> My client now wants it setup so that if the text field is filled in, the radiobox is automatically selected. Any help on this would be greatly appreciated as I am not a JS programmer. Hello All, Below is my code, I am needing to get to where the label name will match the behavior that my field currently does. If nothing is entered the field is changed to a red background.

Hi, I have a JQuery modal window and I am trying to pass the value of its input field to a hidden input field within a form but I can not seem to get the value when it is in the modal window.

Any help would be much appreciated. This is probable very easy, I've tried with normal html and am unable to get my head around it. I would like to in some way replicate how a web browser works. I have a form entry field with a submit button at the top of the page. Under that I have an iframe. I copy the url http://www.bbc.co.uk into the entry field, click submit and the iframe updates with the website. Have looked around and haven't found anything similar. Code so far.... <form target="myURL"> <input type="text" name="goTo"> <input type="submit" name="submit" value="submit"> </form> <iframe src="" name="myURL" border="0" frameborder="0" width="768" height="354"></iframe> Thanks in advanced. Death = $Mill |
