JavaScript - Change Image Based On Multiple Select Options
Hello, I just joined the forum. I'm hoping someone could help me out or point me in the right direction.
I am trying to set up a simple interaction for users. The user would be required to select a width then height from two separate drop down menus. I used this as an example to work from: http://www.w3.org/TR/WCAG20-TECHS/wo...dynselect.html The list of heights would not be available until the user selects a width.(similar to the example link above). Each width would have slightly different heights associated with it. After the user selects a width then height an image would be displayed based on that combination. So for example if the user selects 12w/30h they would see "01.jpg" if the user selects 12w/36h they would see "02.jpg". This would all be done on the same page. The user should be able to update the image by combining the different width/height options indefinitely. If anyone has a link to an example or can provide a basic structure I could build of off I would be extremely grateful, thanks. Similar TutorialsI've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost. When I select the first option nothing appears in the second option. here's the javascript code: Code: function createOption(OptionText, OptionValue){ var temp = document.captcha_form("option"); temp.innerHTML = OptionText; temp.value = OptionValue; return temp; } function valChange(){ var firstList = document.getElementById("emailaddress"); var secondList = document.getElementById("subject"); while(secondList.hasChildNodes()) secondList.removeChild(secondList.childNodes[0]); switch(firstList.value){ case "1":{ secondList.appendChild(createOption("Report Site Browsing Issue", Report Site Browsing Issues)); secondList.appendChild(createOption("Report Page Errors", Report Page Errors)); secondList.appendChild(createOption("Other", Other)); break; } case "2":{ secondList.appendChild(createOption("Report Unauthorized Game", Report Unauthorized Game)); secondList.appendChild(createOption("Report Spam", Report Spam)); secondList.appendChild(createOption("Report Harassment", Report Harassment)); secondList.appendChild(createOption("Report Illegal Activities", Report Illegal Activities)); secondList.appendChild(createOption("Request Account Removal", Request Account Removal)); break; } // .... default:{ secondList.appendChild(createOption("Please select from the first list", "")); break; } } } window.onload = valChange; this is the form code Code: <div class="mailto_form"> <form method="POST" id="captcha_form" name="captcha_form" action="../includes/mailform.php"> <div style="padding-bottom: 1em;">Choose Recipient: <select name="emailaddress" id="emailaddress" onchange="valChange();"> <option value=""></option> <option value="1">Webmaster</option> <option value="2">Admin</option> </select> </div> <div style="padding-bottom: 1em;">Subject: <br /><select name="subject" id="subject"> </div> <div style="padding-bottom: 1em;">From: <br /><input type="text" name="email" id="email" value=""> </div> <div style="padding-bottom: 1em;">Enter the text contained in the image into the text box: <br /><img src="../includes/captcha.php" /> <br /><input type="text" name="userpass" value=""> </div> <div style="padding-bottom: 1em;">Message: <br /><textarea name="message" id="message" rows="10" cols="60"><?php echo "</tex" .

When the user chooses fruit, the second list displays the options apple, orange, banana. When the user changes their choice to veggie, the second select list then contains carrot, corn, potatoes (and the apple, orange, banana disappear). I need some advice on how to do this Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Untitled</title> </head> <body> <form name = "form1"> <fieldset> <legend>Fruit or Veggie</legend> <select name = "S1"> <option name = "fruit">Fruit </option> <option name = "veggie">Veggie</option> </select> <select name = "S2" </select> </fieldset> </form> <script language="JavaScript" type="text/javascript"> ??? </script> </body> </html> 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. Hi there, I am a new javascript guy - struggling a bit but marching on - The following code works fine to set a form field - Code: document.getElementById("ZS_Land").value = (empLand.innerHTML); However, I changed to form field into a select with option list, and I need it to set an option from the select now - the select has the same name/id as the field had, but is not working Any ideas how I do that ? Many thanks in advance Glorifindal Hi JS Experts, I am working on a class registration system that requires students to register for a main class (101, 102 or 103). The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data 1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table) 2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103). How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2. For Example: If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100. If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200 Any help would be really appreciated. Thanks Vinny I am trying to change a character limit based on items changed in a drop down menu. To do this I have one function that will change the posted count based on the currently selected option and another function that is a commonly used char count with a few tweaks. The main issue is getting the value of the currently selected option. I know that selectedIndex will return the position of the selected element rather than the actual value. I tried to code around that. I've tried every method I could find on google and nothing works. So, I may have a bigger problem on a higher level that I just don't understand. If any of you can take a look at my code and give me your thoughts I would be most appreciative. Thanks!

I need a function that change multiple images on click maybe by id Ex.: PHP Code: <table> ..... <td><img src="folder1/image1.jpg"></td> <td><img src="folder1/image2.jpg"></td> <td><img src="folder1/image3.jpg"></td> <td><img src="folder2/image1.jpg"></td> <td><img src="folder2/image2.jpg"></td> <td><img src="folder2/image3.jpg"></td> ..... </table> NOW BUTTONS (IMAGES) PHP Code: <!-- clicking this imagen will change to another button image and will change the folder1/image1.jpg and folder2/image1.jpg --> <div><img src="buttons/buton1.jpg" alt=""></div> <!-- clicking this imagen will change to another button image and will change the folder1/image2.jpg and folder2/image2.jpg --> <div><img src="buttons/buton1.jpg" alt=""></div> <div><img src="buttons/buton2.jpg" alt="click here to change only the image1.jpg in folder1, folder2 and this image"></div> <!-- clicking this imagen will change to another button image and will change the folder1/image3.jpg and folder2/image3.jpg --> <div><img src="buttons/buton3.jpg" alt="click here to change only the image1.jpg in folder1, folder2 and this image"></div> really, I don't know much about javascript, I'm waiting for your help. actually, I have loaded jquery-1.2.6.min.js I have a select box that has ~7000 options, that based on a different dropdown select & input field, gets filtered to 0 - 300 entries. I have another select dropdown that has 13000+ options in total for all the ~7000 entries, but each entry may have 1 to 5 options of these 13000. Is there a way to change the options of the last select dropdown based on what the user chooses in the filtered select box? Currently the idea I'm having is to have the browser load all 13000+ items and filter out the ones that don't apply to the currently selected item, but I'm not sure what kind of lag the user would experience while the browser loads & filters through all these items. Any help would be appreciated. Thanks. Please i am new here and i need some urgent help.

I'm trying to figure out a way of having + and - buttons which cycle through the options in a select box such as: <select name="distance" id="jr_radius"> <option value="0.5">0.5 Miles</option> <option value="1">1 Mile</option> <option value="3" selected="selected">3 Miles</option> <option value="5">5 Miles</option> <option value="10">10 Miles</option> </select> So far I've only been able to have a button change the select box to a specific value, or add or subtract to a numerical value. Both of which aren't quite right. Ideally if the default value is "3" then clicking the + button could make it "5" and clicking the same button again would make it "10". Visa versa, the minus button would make the value "1" and then if pressed again it would become "0.5". Does that make sense? Any help will be greatly appreciated! This code is supposed to batch transfer options between selects. It works flawlessly for single values, but when I select multiple options, all of them get deleted, but only one transferred.
