JavaScript - Using Pull Downs And Calc Birthdate
Hello,
I am trying to use select options to get birthdate and calculate the age. I got the birthday with "birthDay = document.form1.selDate;" However i'm lost on the birthMonth and birthYear. I've looked at lots of examples. The birthMonth probably needs to be converted to integer, or use 1 thru 12 rather than Jan thru Dec. But birthYear i'd think would come back as a valid number. Is anyone familiar with this? Thanks. Code: <html>
<head>
<title>Main</title>
<script language="javascript">
<!--
function Age()
{
var birthDay;
var birthMonth;
var birthYear;
var userAge;
var currentDay = new Date();
var dayNow = currentDay.getDate();
var monthNow = (currentDay.getMonth());
var yearNow = (currentDay.getFullYear());
birthDay = document.form1.selDate;
// Don't know how to get birthmonth????
// birthMonth = (parseInt(document.form1.selMonth.value)-1);
birthYear = document.form1.selYear;
// alert("birthyear " + birthYear); ( gives "birthYear [object HTMLSelectElement]")
if((monthNow > birthMonth)||(monthNow == birthMonth & dayNow >= birthDay))
{ userAge = birthYear; }
else { userAge=birthYear+1;}
alert("As of today, " + currentDay +' \n'+", you a " + (yearNow - userAge) + " years old");
}

The only problem I am facing is changing form.answer.value It won't change, why not? Hi, First time user of Javascript and built an online calculator, trouble is I dont know where or how to code it so the answer ends with only 2 decimals I have embedded code, help appreciated. Personally I think it's a miracle the darn thing works. Link to page it's on. Any help appreciated, I have searched and read but after hours of trying stuff gave up. <!-- function treevalue() { document.volume.result.value=(((3.14159*((document.volume.radius.value)*(document.volume.radius.valu e)))*(document.volume.height.value))/3)*(document.volume.base.value)*(document.volume.e.value)*(document.volume.fv.value)*(document.volum e.l.value); } // --> Thanks Eric Hi, I'm trying to create a Invoice form with javascript.

Its not working and i hope you can help so far i've got Code: if (document.profile_quote.thickness.selectedIndex == "3" && document.profile_quote.machine.selectedIndex == "1") document.profile_quote.cutspeed.value = "34444" I have a date of birth drop down for 'Day', 'Month' and a text field for Year. How can I get the select value of the drop down and year text field into a single text field, separated by '-'? The single text field would need to update if someone changed the drop down / year selections. Hope someone can help - I'm stumped! I am using the following code to show / hide form elements within a div based upon the drop down choice. Does anyone know how this code can be amended to use multiple drop downs within one form? Code: <html>

Thanks in advance! Hi guys, it's a bit of a large question but I've been messing around with code for a while, and nothing seems to work... Basically, I need to make, a 'dynamic theme changer'. Basically what I need to do is have several drop down boxes, each one with some colours available as options. When you select one, it automatically (without refreshing the page) updates a certain element's style. For example, if you selected green as one colour and red as another, the element linked to the first drop-down would turn green, and the element linked to the second drop-down would turn red, and so on so forth. It then needs to have a 'save' button, which saves the settings, and adds a cookie with the style details so that when they visit the page again it's still personalized. There also needs to be a cancel button which discards all changes. I know it's a large question but I'm ripping my hair out over this one! =P Your help is much appreciated. Hi all, I think I have posted in the right place, if not appologies. Anyhow, I am currently creating a website for my canvas printing business and run into a few javascripting issues. I am trying to create a small navigation form whereby a customer can select from a dropdown the required width of canvas, this selection will then populate a second dropdown with a choice of canvas heights. Ok, so trawling many sites I came across some javascript that I was able to chop about and have this part sorted. The problem now is that I would like to include a submit button that when clicked takes the customer to a webpage based on their two dropdown choices, and being a complete newby when it comes to javascript I am stuck trying to include the script to enable this. eg: if they select '20" (51cm)' from the first dropdown and '16" (41cm)' from the second dropdown, they will navigate to "http: / / 20x16.co.uk" canvas print page. I have not currently created the canvas print pages so am unable to give the URLs of the pages. However if somebody can lend a hand to get me started and indicate where the desitnation URLs need to be added, I can drop these in later. The way that the script is currently written, the linked url could be based soley on the choice made in the second dropdown. I have a draft page with the working dropdowns he http://merchant.auctivacommerce.com/...iewtheme=32189 And the code that I currently have is: Code: <script type="text/javascript">

As mentioned, Javascript is completely new to me but I am attempting to learn. Any help would be greatly appreciated. Wayne Is there a way to pull a text off a certain div on a page, and put it into a javascript string? I'm certain that the field has a particular name and id that I can use, if need be.
So I have been stuck for a couple days now on this problem. I am trying to create a form to edit existing data in my database. I have 2 drop down boxes( category then item) they do not work correctly. I am using php to populate the drop down boxes but there is nothing dynamic about doing this. I think I need to totally rewrite the page using java script or Ajax but I don't know what parts. So I want the user to select a category from a drop down list populated by database then have it populate the item list(so I think both of these need to be java script in case they change the category it will re populate the item list). Then I just want the selection of the item to pull the information to my form so they can update it and save the update(which I am pretty sure I can save the update as a php function but need to populate the item editable information in java script). I am really looking for help on how to setup the page with java script to make database queries and use the results to update parts of the page. In case you confused here is my flow: page loads -User selects catagory query database for item list (on change event it think) -User selects item Item information is pulled and displayed from database(cost, serial number, quantity) (another on change event) -User is able to edit information and save updated results(run an update.php...) Here is a quick rundown of my code: ----I want this query to select the item based on the selected category (itemcat) <? $result = mysql_query("SELECT itemnum, itemname FROM item where itemcat = 'Item1' ", $con); //yes this is hard coded right now mysql_close($con); ?> ----end of head start of body---- ---This category list is hard coded since the categories will almost never change--- <td>Select Item</td> <td width="142"><select name="itemcatsearch" size="1"> <option value="1" selected="selected">Item1</option> <option value="2">Item2</option> <option value="3">Item3</option> <option value="4" >Item4</option> <option value="5">Item5</option> <option value="6">Item6</option> <option value="6">Item7</option> </select></td> <td width="268"> <!-- Dynamic item list -- this is just the result of the query run at the top and placed into a second drop down box> <select name="itemcat" size="1"> <? while($row = mysql_fetch_array($result)){ ?> <option value="<? echo $row['itemnum']?>" > <? echo $row['itemname']?> </option> <? } ?> I know its ugly sorry I am a noob. Any help or direction would be greatly appreciated. I am developing a web application based on a Java servlet. The servlet outputs html and javascript codes and receives some result from a thread, which works behind the servlet. Thus, html and javascript codes dynamically varies. While result equals null (a thread is not completed), it shows "Currently processing," and refreshes Code: <div id="load"> - </div> every second automatically. After receiving some results, it should stop automatic refreshing and show "Done." I wrote source codes described below. It shows "Done" after getting some results, but does not stop refreshing. However, when I manually refresh the page (Ctrl-R), the script is loaded and reloading is stopped. How can I pull javascript codes automatically? Code: <head>
<script type=\"text/javascript\">
var auto_refresh = setInterval(
function start()
{
$('#load').load('./Page' + ' #load');
}, 1000);
</script>
</head>
<div id="load">
if (result == null) {
// the variable result is received from a behind thread every second.
// while a thread is processed
<p>Currently processing. <p>
} else {
// a thread is completed
// try to stop reloading
<script type=\"text/javascript\">
clearInterval(auto_refresh);
</script>
<p>Done. <p>
}
</div>
I'm working on an internal website at work and employees have a cookie created when they login to the customer support tool. The filename is cookie:username@domain.com/ and I'd like to use javascript to pull a variable for their username to plug into a URL for a unique link when they're viewing one of our intranet pages. I'm a Javascript newbie so any help is appreciated. @domain.com/ will always be the same but I don't know how to pull the unique username from the filename of the cookie. I don't need to actually read the cookie. Thanks! Hey all, Objective: - when you select other the pull down menu is replaced by the text field. Currently: - Gotten it to the level of when you select the other the text field appears. Question: - HOw can I modify the code so when I select the other menu option from the pull down menu and it replaced by the text field? Quote: <script type="text/javascript"> function togglefield(val) { var o = document.getElementById('other'); (val == 'Other')? o.style.display = 'block' : o.style.display = 'none'; } </script> and the form: <form action="" method="post"> <select name="sel" id="sel" onChange="togglefield(this.value);"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="Other">Other</option> </select> <input type="text" name="other" id="other" style="display: none;"> </form> I have an function that shoud be activated when the pull down menu in triggerd, the if functions is corresponding to the same menu overig_eenh[] PHP Code: function overig_tot_abs(selectVeld, nr) { // Prijs totaal if (document.getElementsByName('overig_eenh[]')[nr].value == 'totaal') { document.getElementsByName('overig_totaal[]')[nr].value = (document.getElementsByName('overig_prijs[]')[nr].value).toFixed( 2 ) } // Prijs kg if (document.getElementsByName('overig_eenh[]')[nr].value == 'kg') { document.getElementsByName('overig_totaal[]')[nr].value = (document.getElementsByName('overig_prijs[]')[nr].value * (document.getElementsByName('materiaal_tot_gew[]')[nr].value + document.getElementsByName('plaat_tot_gew[]')[nr].value)).toFixed( 2 ) } // Prijs verf opp. if (document.getElementsByName('overig_eenh[]')[nr].value == 'verf_opp') { document.getElementsByName('overig_totaal[]')[nr].value = (document.getElementsByName('overig_prijs[]')[nr].value * (document.getElementsByName('materiaal_tot_verf_opp[]')[nr].value + document.getElementsByName('plaat_tot_verf_opp[]')[nr].value)).toFixed( 2 ) } } Form (in loop): PHP Code: <tr> <td><select name="overig_omsch[]" > <option></option> <option value=Engineering>Engineering</option> <option value=Inkoop bev.middelen>Inkoop bev.middelen</option> <option value=Inkoop snijwerk>Inkoop snijwerk</option> <option value=Spuiten>Spuiten</option> <option value=Stralen>Stralen</option> <option value=Transport>Transport</option> </select> </td> <td><select name="overig_eenh[]" onChange="overig_tot_abs(this, 0)" > <option></option> <option value="totaal">Totaal</option> <option value="kg">Per Kg</option> <option value="verf_opp">Per 1m2</option> </td> <td><input type="text" name="overig_prijs[]" size="10" value="" /></td> <td><input type="text" name="overig_totaal[]" size="10" style="text-align:right;background-color: #f1f1f1" value="" readonly="readonly" /></td> <td><input type="text" name="overig_opmerkingen[]" size="75" value="" /></td> </tr> Hi, I'm new to these forums so if anything is out of the ordinary let me know for next time or so I can correct it - please. I am also not very good with javascript but I am trying to learn the whole concept. Anyways, I am supposed to create pull down menus when I open this page: Code: <?xml version="1.0" encoding="UTF-8" ?>

The most famous of fictional detectives, Sherlock Holmes
first appeared in print in 1887, in stories written by the Scottish author
and physician, Sir Arthur Conan Doyle. Holmes is famous for his use
of deductive reasoning to solve difficult and complex cases. Almost
all Holmes stories are told in the first-person narration of
Dr. John Watson, Holmes' closest friend and confidant.</p>
<p>Doyle wrote four novels and 56 short stories in the Sherlock Holmes
canon. The first Holmes tale was the novel, <i>A Study in Scarlet</i>,
which chronicled the meeting of Holmes and Watson and covered their
first case together. As Doyle wrote additional tales, the Sherlock Holmes
stories grew in popularity, becoming a regular feature of <i>The
Strand Magazine</i>. Desiring to explore other literary pursuits, Doyle
grew tired of the detective and killed off Holmes in the short story
<i>The Final Problem</i>. However, public acclaim and a desire for more
Holmes stories eventually persuaded Doyle to resurrect the popular
detective, bringing him back in <i>The Adventure of the Empty House</i>.</p>
<p>Doyle's final Holmes story, <i>His Last Bow</i>, appeared in 1914, but
that did not end the public's fascination with Holmes and Watson. Basil
Rathbone brought the character to the silver screen in 14 movies
loosely based on Doyle's original stories. In more recent years,
Jeremy Brett played Holmes to great critical acclaim over four seasons of
the BBC series, <i>The Adventures of Sherlock Holmes</i>. In all, Holmes
has been played by over 70 actors appearing in over 200 films.</p>

Hi all I have relatively easy task I need to accomplish but as per usual I have very little idea of how to do it. I have done a google search to no avail. Basically I need to: 1. Pull a value from inside a div Code: <div id="number">(invoice #1017)</span> 2. Populate a form input field with that value. Does this make sense? If not let me know if you need any more info. Thanks Hello all. I have created a snippet of javascript code that will do the following: 1. read the window URL 2. depending on the window URL, a word will be placed into a hidden form field. 3. Person submits form...etc., etc. Here is what I have. Let's say that I have a single landing page with a simple form on it. I would like to reference the referred URL by pulling a part of the window URL into a hidden field of the form. Let's say the three URLs a http://www.whatever.com/index.htm?id=ref1 http://www.whatever.com/index.htm?id=ref2 http://www.whatever.com/index.htm?id=ref3 I have created a javascript that takes the exact URL and check for equality. If the URL is equal, it will place the corresponding id into the hidden form field. See my code below. Code: <script type="text/javascript">
var lead_source = window.location.href
{
if (lead_source == "http://www.whatever.com/index.htm?id=ref1")
{
document.writeln("<input type=hidden name='lead_source' id='lead_source' value='ref1'>");
}
else if (lead_source == "http://www.whatever.com/index.htm?id=ref2")
{
document.writeln("<input type=hidden name='lead_source' id='lead_source' value='ref2'>");
}
else if (lead_source == "http://www.whatever.com/index.htm?id=ref3")
{
document.writeln("<input type=hidden name='lead_source' id='lead_source' value='ref3'>");
}
}
</script>
What I am looking to do is modify the code to only look at the "id" variable, not the entire URL. That way, if I add any additional items to the URL I will not have to change the code. I guess I am looking for an extra step of parsing the URL...maybe. Thanks for your help I'm looking at creating a set of customer contact forms. I'd like to be able to have a main contact page where the visitor fills in general info like name and such, and then clicks a link to get into the specific area form he needs. I've done VB programming and used it to manipulate an IE document object. I've explored JavaScript and managed to code one or two IF functions. I'm wondering if I open the linked form in a new window, can I use JS to pull the info from the first window and insert it into the new window? Seems like it would be easy, but I don't know so I'm asking. (MasterofFollies gave me a PHP solution in http://www.codingforums.com/showthread.php?t=187819 , but I havene't had any time at all to give myself to understanding it!) Ed |
