JavaScript - Help Using Correct Selection Structure To Display Messages Based On Two User Inputs
I apologize for all the text I'm about to type, but I just want to make sure I explain my problem in detail.
So I have created a simple Weather Forecast algorithm containing the JavaScript code that uses a prompt to allow a user to enter a temperature in degrees Celsius, and based on the degrees entered (temperature scale is below), the program will display one of the following messages based on the selection structure I have created: (Kindly find attached .txt file of my entire code, I wasn't able to upload an HTML file.) -18 degrees Celsius: "Bundle up! It's freezing out there!" -18 - 0 degrees Celsius: "Pretty cold with a chance of snow!" 15 degrees Celsius: "Don't forget your jacket. It's still chilly out!" 16 - 27 degrees Celsius: "Perfect, lovely weather... unless it rains." 28 - 35 degrees Celsius: "Nice and warn. Go for a swim." 35 degrees Celsius: "Really hot! Best to stay in air conditioning." HELP Now i want improve on the same program and let the user enter the degrees in either unit using a prompt to ask the user whether the entry is Celsius(C) or Fahrenheit (F) (F scale is below) and use the correct degree breakdown to display the same messages: Less than 0 degrees Fahrenheit: "Bundle up! It's freezing out there!" 0 - 32 degrees Fahrenheit: "Pretty cold with a chance of snow!" 33 - 59 degrees Fahrenheit: "Don't forget your jacket. It's still chilly out!" 60 - 80 degrees Fahrenheit: "Perfect, lovely weather... unless it rains." 81 - 95 degrees Fahrenheit: " Nice and warn. Go for a swim." Greater than 95 degrees Fahrenheit: " Really hot! Best to stay in air conditioning." I'd appreciate if anyone can help me with this. Again, I've attached my original file where the user can only enter in degrees Celsius and gets the corresponding messages. I have tested it and it works perfectly.

First, here is part of a form I have: Code: <select name = "pulmonologist" >
<option selected="" value="">---Select---
<option value="none">None</option>
<?php
while ($row2 = mysql_fetch_assoc ($results2)) {
?><option value = "<?php echo $row2['staff_name'];?>"><?php echo $row2['staff_name'];?></option>
<?php }
?>
</select>
Ok now I want to echo the value that the user selects on the SAME page (i.e. before the submit button is pressed) (so I can't do it with php, I need javascript) like this: Code: <input type="submit" value = "Contact <?php echo $pulmonologist;?>" /> Can you tell me how to do this? Thanks! Hey everyone, I have a simple html form that asks a user to select a state from a drop down list. Later, in the same form, there's a question that needs to display an image of the state they previously selected from the drop down menu. How can I accomplish this using javaScript?
I want to have several forms on one page that are not displayed until a selection is made from the category drop down box(select element). The form displayed will depend on the selection made. Here is the code I have so far. Please help. Code: <body> <label id="Label1">ADMINISTRATOR CONSOLE - ADD AND EDIT ASSETS<br /> </label> <form action="" method="post" style="border-style: ridge; width: 311px; height: 37px;" name="myform"> <table> <tr> <td>Select Category:</td><td> <select name="category" onchange="set_sub_category()" style="width: 157px"> <option selected="selected" value="select">Select an Option</option> <option value="add">Add Category</option> <option value="district">Council District</option> <option value="region">Region</option> <option value="pom">POM</option> <option value="proptype">Property Type</option> <option value="assetcat">Asset Category</option> <option value="assettype">Asset Type</option> <option value="property">Property</option> <option value="asset">Asset</option> </select> </td> </tr> </table> </form> <form style="display:none" action= "admin_console_new.html" onsubmit="return (validate_form(this)& validate_list(this))" method="post" style="border-style: ridge; border-width: medium; height: 154px; width: 346px;" name="district"> <table style="height: 86px"> <tr> <td>Select District Value:</td><td> <select name="district"> <option selected="selected">Select an Option</option> <option>Add Council District</option> </select> </td> </tr><tr> <td>Enter District Name:</td><td> <input name="name" type="text"/> </td> </tr><tr> <td>Enter Description:</td><td><textarea name="description"></textarea> </td> </tr><tr> <td><input type="submit" value="Submit" name="Submit3" /><input type="reset" value="Reset" /> </td> </tr> </table> </form> I want to make a search form where inputs only appear if a certain selection has been made. For example the user selects "Green" then the input "X" appears, and if the user clicks "Black" then input "Y" appears. How can this be done? If so, can someone give me a basic example in code that I can use to copy off?
Hi all, I am trying to find out if it's possible to auto populate a text input based on the value of another. e.g. there is an input called name.. the user completes this and enters something like John, then in the same form there is another input called username. Once the person enters John in the name field, the username automatically displays John. I'm not sure how doable this is, I'm not very familar with Javascript, so any advice would be greatly appreciated. Many thanks, Greens85 Hi, I am a complete beginner at Javascript(started a few days ago) and was having trouble with some functions. I'm trying to get the inputs required to change based on an option selected in a drop down menu. I was intending to run different scripts based on whatever is chosen but when I ran a test using an alert function, I realized my code isn't working. I went online and found really confusing stuff like "running a for loop through an array to make a dynamic select feature". Still confused any help would be appreciated. My code thus far: <html> <head> <title>Practice</title> <script language="javascript"> function myScript() { var loanType = document.form1.loan.options.text if (loanType == "Bank A") { alert("Working") } } </script> </head> <body> <form name="form1"> <select id="loan" name="loan" onchange="myScript"> <option></option> <option>Bank A</option> <Option>Bank B</Option> </select> </form> </body> </html> Reply With Quote 01-08-2015, 10:52 AM #2 Primus View Profile View Forum Posts New Coder Join Date Oct 2014 Posts 92 Thanks 0 Thanked 14 Times in 14 Posts Code: <script>

Maybe not the best way, but it does the trick. Reply With Quote 01-08-2015, 11:43 AM #3 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 You have quite a lot of obsolete code:- 1) It is obsolete to assign a name to a form and permitted only for the sake of backwards compatibility. 2) <script language=javascript> is long deprecated and obsolete. Use <script type = "text/javascript"> instead (in fact also deprecated but still necessary for IE<9). 3) Scripts should normally be placed right in front of the </body> tag. Any script can optionally go in the head if you wrap it inside a load event listener so that it can't run before the page loads. 4) Use the value of a select box option, not the text. 5) It is recommended that you place the opening brace following the function, if, else, for, while, do, switch, and try statements on the same line and not on the following line. Apart from that every Javascript statement should be followed by a semi-colon (;). It is quite possible to disregard this advice, but if you do one day it will rise up and bite you in the undercarriage. Code: <html>

The Warrington players can hang their heads high. - Commentator, BBC Radio 2 I have the two functions below, I want to write a function that puts them into a chart, I have the chart sorted etc but just struggling with how to get the actual validated users inputs from these two functions into the chart, I've tried document.write('<td> $' + productIndex + '</td>'); into the chart but that wouldn't work anyway as there could be multiple inputs? Just need a way to get the output really. function getProductChoice(min, max) { var getProductChoice = function(min, max){ do{ var productIndex = parseInt(prompt('Enter your product choice; 0-5', '0')); } while( isNaN(productIndex) || productIndex < min || productIndex > max); }; getProductChoice(0,5); } function getProductQuantity(max) { do{ var productIndexQuantity = parseInt(prompt('How many would you like?', '0')); } while( isNaN(productIndexQuantity) || productIndexQuantity < 0 || productIndexQuantity > max); }; getProductQuantity(MAX_QUANTITY); Hi all. I'm trying stuff out for learning. What I would like to do is display the first error message in array ie 'required' if its still wrong when validate again I want message two to display ie 'still required' but I can't work it out. As expected, I always get the last message. Can it be done as I would like or is it done another way? Code: var errmail = [];
errmail[0]="Required";
errmail[1]="Still required";
errmail[2]="Oi idiot, enter a VALID email";
/other code here/
email checked and failed
for (i=0; i<errmail.length; i++)
document.getElementById("emerr").innerHTML = errmail[i] ;
/other code/
any positive input very welcome LT ps:-)smile Hi, I'm new here, and I'm a programming newb but am very interested in learning and possibly pursuing programming in the future. As such, I'm taking an intro to Javascript class at my university, and our homework is to make a function that when called upon makes a diamond out of *'s. It is supposed to do so by prompting a user for an int and then makes a diamond shaped object with the inputted number of stars in the middle of the diamond. an example of what this would look like (if a user entered in "5" to the prompt): *<br> ***<br> *****<br> ***<br> *<br> I am not sure how to set up this for loop, and have been trying so many different codes and have come nowhere close. Any help or insight would be so much appreciated. I'm wanting to put a piece of code on my website that will display when our next meeting will be. We have 2 meetings per month. I'm thinking what I need to do is create a code that gets the current month, day of month, and year then combines it together somehow, and if that combination is in a certain range a particular statement, "Next meeting is MM, DD YY." or "Next meeting is today." is displayed. If date is equal to or between 01012012 and 01112012, "Next meeting is January, 12 2012" is displayed. If date is equal to 01122012, "Next meeting is today" is displayed. If date is equal to or between 01132012 and 01252012, "Next meeting is January, 26 2012" is displayed. If date is equal to 01262012, "Next meeting is today" is displayed. ...that kind of thing. How would I combine the month, day of month, and year? Would 48 if statements be what I need to do? Sorry, I'm pretty new to javascript. If there's a better way to do this, please let me know. Thanks, CJ Here's part of the code, problem I have is I have it set up for 5 rows, I need it to be able to make more than this, but not sure how many more, this is dependent on user input, how should I go about this? Also how would I go about making the users orders correspond with the right item number? I'd need to sort the array somehow? document.write('<table border="1">'); document.write("<tr>"); document.write('<th colspan="5">ORDER</th>') document.write("</tr>"); document.write("<tr>"); document.write('<th align="left">Item #</th>'); document.write('<th align="center">Name</th>'); document.write('<th align="center">Price</th>'); document.write('<th align="center">Quantity</th>'); document.write('<th align="center">Total</th>'); document.write("</tr>"); document.write('<td align="center">0</td>'); document.write('<td>' + productName[0] + '</td>'); document.write('<td> $' + sausagePrice + '</td>'); document.write('<td> ' + orderItemQty[0] + '</td>'); document.write('<td> ' + sausageTotal + '</td I want to insert text to a textarea based on the selected text. It should insert tags like the buttons for posting on this form work. Ie: If 'bar' is selected, and I click 'b', then I get: Code: Foo bar frog becomes: Code: Foo <b>bar</b> frog I found some code that works for firefox, but I need it to work in explorer as well. Do you have any ideas or examples how to do this? Here's the code I'm currently using. ( Works right in ff3. In IE7 it appends the tags at the end of the text. I want it to insert based on my selection. ) Usage: Code: <a onclick="insertTags('<b>', '</b>', document.forms.formpost.text);return false;" href="javascript:void(0);">[ Bold ]</a>
insert function: Code: <script type="text/javascript">
// Surrounds the selected text with text1 and text2.
function insertTags(text1, text2, textarea)
{
// Can a text range be created?
if (typeof(textarea.caretPos) != "undefined" && textarea.createTextRange)
{
var caretPos = textarea.caretPos, temp_length = caretPos.text.length;
caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text1 + caretPos.text + text2 + ' ' : text1 + caretPos.text + text2;
if (temp_length == 0)
{
caretPos.moveStart("character", -text2.length);
caretPos.moveEnd("character", -text2.length);
caretPos.select();
}
else
textarea.focus(caretPos);
}
// Mozilla text range wrap.
else if (typeof(textarea.selectionStart) != "undefined")

Hi Guys, I'm a new member, so hello all! I'm ok at html/xhtml, but i know nothing about javascript, so hoping someone here can help! Basically, I have a contact form on my website that offers 2 different types of contact: RSVP and Other. these two types are available in a selection box. What I want to happen is when the "RSVP" option is selected, the following options are displayed: "Yes/No" radio buttons "additional info" textarea And when the "Other" option is selected, the following option is displayed: "Message" text area How can i make this happen?! i've tried searching the internet but I can't get anything i find to work. I can't even get the elements to hide! At the moment, my form looks like this: - Code: <form method="POST" action="contact.php"> <table class="contact"> <tr> <td>Name:</td> <td><input type="text" name="name" size="20"></td> </tr> <tr> <td>Email:</td> <td><input type="text" name="email" size="20"></td> </tr> <tr> <td>Contact Type:</td> <td><select size="1" name="type"> <option value="rsvp" >RSVP</option> <option value="other">Other</option></td> </tr> <tr> <td colspan=2> </td> </tr> <div id="rsvp" style="display:none;"> <tr> <td colspan=2><input type="radio" name="response" value="y"> Yes Please!</td> </tr> <tr> <td colspan=2><input type="radio" name="response" value="n"> Sorry, but No. </td> </tr> <tr> <td colspan=2>Additional Comments (Please include any special dietary requirements): </td> </tr> <tr> <td colspan=2><textarea rows="5" name="rsvpmsg" cols="30"></textarea></td> </tr> </div> <div id="other" style="display:none;"> <tr> <td colspan=2>Message:</td> </tr> <tr> <td colspan=2><textarea rows="9" name="othermsg" cols="30"></textarea></td> </tr> </div> <tr> <td> </td> <td><input type="submit" value="Submit" name="submit"> <input type="reset" value="Reset" name="reset"></td> </tr> </table> </form> Please note, the style="display:none;" parts aren't even working I appreciate any help you can give! thanks! Hi, i am building a website form which I would like the user to select a product of interest. Some products are three tiered and some are two tiered. 1. Example of three tier (3 dropdowns required only): Scooters (dropdown 1) Three Wheel Scooters (dropdown 2) Delux 503S Bird Scooter (dropdown 3) 2. Example of two tier (2 dropdowns required only): Standing Bikes (dropdown 1) Children 300 Series (dropdown 2) If the user wants to submit their interest for one of the products, I need to have at most 3 dropdown menus. So in Example 1, I would have 3 dropdowns in my form. Dropdown 1: Scooters Dropdown 2: Three Wheel Scooters Dropdown 3: Delux 503S Bird Scooter In Example 2, I would only need to use the first 2 dropdown menus. (Obviously the first dropdown would contain 'Scooters' and 'Standing Bikes' in the menu list) The below code is perfect except, I would like to alter the code so that the second and third dropdowns are hidden until a selection from the first drop down is made. Once for example, 'Standing Bikes' is selected from the first dropdown menu, the second dropdown menu appears and the third remains hidden due to the fact that it is not required. If I selected Scooters from the first dropdown menu, the second dropdown would appear listing all items associated with this and at this point the third dropdown menu is hidden. If i select 'Three Wheel Scooter' from the second dropdown the third dropdown menu now appears listing all Three wheel Scooters such as 'Delux 503S Bird Scooter'. I hope this makes sense. Let me know if you require clarrification. Here is the code: Code: <script language="JavaScript" type="text/javascript">

Hi, On a registration form I have 4 fields that are all dropdown select fields. NAME, CLASS-1, CLASS-2, CODE 1) I would like to activate the CLASS-1, CLASS-2, CODE fields only if the NAME IS Selected from the dropdown. 2) Also would like to make the CLASS-1, CLASS-2 as required fields if the NAME is selected from the dropdown. How can I achieve this? Can I use some kind of a server event to activate / deactivate the fields on the form? Please advice Thanks Vinny I have a registration form that I am working on in which I need to assign a price to each option in a selection box then write that price in the document. Then I have a radio button that will add (different amounts based on selection) to that price before it is written. Then I have another radio button that just needs to write a price based on its selection. Both of these values will be written and then totaled. (See below for a less confusing explanation) On HTML form: >drop down list (name courseName, value of selections 1,2,3,4) > radio button (name returnStudent, value of selections 1,2) > radio button (name bookNeeded, value of selections 1,2) Table (name totalprice) at the bottom of the form: price1: price of courseName plus returnStudent (td with name tuitionprice) price2: price of bookNeeded (td with name bookprice) Total of the above (td with name totalprice) This is what I am trying to make work... Code: var selectedCourse = document.onsiteRegistration.courseName.value;
var selectedStudent = document.onsiteRegistration.returnStudent.value;
function setTuition()
{
if (selectedCourse == "1" && selectedStudent =="1")
{
document.write("12345");
}
if (selectedCourse == "1" && selectedStudent =="2")
{
document.write("54321");
}
}
Then in my HTML I have simply put this to call the function and write it where I need it to be placed. <script>setTuition()</script> I am trying to find some examples of something like this but all I am coming up with is shopping carts and that is not what I need here. I am fairly confident that I can program the second part (totaling) if I can only get the selections to populate the different prices for me. If someone could point me in the right direction I would be very grateful! form is .asp scenario: I have 3 radio buttons above number of boxes (dropdown). I want the dropdown selection box greyed out on selecting Electronic (radio button) Physical (radio button) Image (radio button) Electronic (radio button) Number of Boxes [dropdown box] Thanks for your help I am new to coding. Codes for Dropdown menu based on radio buttons selection needed!? I need urgent help with this: I need codes for a dropdown menu that is altered by radio buttons. I want to insert the value selected from the dropdown menu into a table. Dear all, background information: I did code a timesheet management system for my company with PHP where the user has to submit time entries and has an online form with several start and end times. The start and end times are all simple HTML select option dropdowns. I want that the first End time selection will be the next start time selection. Basically a simple dependency of the dropdown. My approach was that I want to solve this with JavaScript. In my php code I am echoing the following (in this select the end times are the values): echo "<select class='normal' name='$field_id' onChange=set_time_hour(this.value,'$field_id_js')>"; When the user changes then the end time dropdown the next field (next start time entry) should be changed accordingly. The javascript looks like this function set_time_hour(hour_value,next_field){ alert (hour_value); alert (next_field); document.getElementById(next_field).value = hour_value; } The alert calls are giving me the right values. but the document.getElementById(next_field).value = hour_value; is not working. What is wrong there? Do you have an idea? How can I change the value of a select box with Javascript? The select box values are already popoluated with PHP so I just want to select the right value. How can I hide/disable the submit button if the name Todd is selected? Code: <html> <head> </head> <body> <form name="people"> <select name="group"> <option value="Pick Your Name">Choose</option> <option value="Tom">Tom</option> <option value="Freddy">Freddy</option> <option value="Todd">Todd</option> <option value="Fred">Fred</option> <option value="William">William</option> <option value="Johnson">Johnson</option> </select> <INPUT TYPE=submit VALUE="submit"> </form> </body> </html> |
