JavaScript - Change From Input Field To Select Options Causes Problems
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 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" .

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. all i have to do is the image to change automatically based on the option you selected from the drop down list. here is the code, any help is appreciable. thanks in advance. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <style type="text/css"> img{ height:95px; width:95px; display:block; margin-top:10px; } #caption{ font-family:Verdana,tahoma,arial; font-size:8pt; text-align:left; display:block; width:250px; } </style> <script type="text/javascript"> window.onload=function() { var caption=['Default Image Caption', 'begonia', 'daffodils', 'mixture', 'natural', 'purple', 'red flower', 'sunflower', 'tulip', 'two flowers'], // This will be your images caption bp='..\images', //base url of your images imgnum=9, //Number of your images.

An example is here; https://twitter.com/about/resources/...widget_profile You can see in the example how you can enter a different twitter user account, then hit 'test settings', leading to related twees being displayed.

Thx Hi, what would be the best way to have a hidden array of possible text directed at a textarea and then if something is not within that array "onfocus", a certain select option is chosen within that form? Thanks Hey chaps, hope someone can help with this: I have a PHP form, with a couple of dynamic Select menus, which are populated from two SQL tables: // tbl_main_colour: Code: ID, NAME 1, Red 2, Blue 3, Green // tbl_shade_colour: Code: ID, NAME, FK_MAIN_COLOUR_ID 1, Light Red, 1 2, Dark Red, 1 3, Light Blue, 2 4, Dark Blue, 2 5, Light Green, 3 6, Dark Green, 3 What I'm after is something to filter the second select option, after the first select option has been chosen // Select 1: Code: Red // Select 2: Code: Light Red Dark Red I'm pretty sure this is possible, but not sure how to go about it, any help would be most appreciated. Hello, I am trying to make a simple code that has a selection list (with the choice fruit or veggie). 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> 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. Not 100% sure why or how to make this work. I have 5 options in a select drop-down. Only two of them are to disable a text field. I have written it successfully to disable on one option. How would I add the second option? I have tried many different ways, and i know its something small that i am missing. Below is the code that does not work but shows the 2 options that disable my text field. Code:
<script type="text/javascript">
function type_disable() {
var qr_type = document.getElementById('qr_type');
var qr_owner = document.getElementById('qr_owner');
if(qr_type.value == 'bio' || 'rebrand')
qr_owner.disabled = true
else
qr_owner.disabled = false
}
</script>
Code: <tr> <td align="right"><span class="re">*</span>Type: </td> <td align="left"> <select id="qr_type" name="qr_type" onChange="type_disable()"> <option value="0">Select Type</option> <option value="property">Property Code</option> <option value="ipw">IPW Code</option> <option value="bio">Biography Code</option> <option value="rebrand">Rebrand Code</option> <option value="property_rebrand">Property-rebrand Code</option> </select> </td> <td ></td> </tr> <tr> <td align="right"><span class="re">*</span>Owner: </td> <td align="left"> <input type="textbox" name="qr_owner" id="qr_owner" size="30" value=""/></td> <td ></td> </tr> Thanks for any help!

If i have an existing HTML Select statement with options specified, and then based on an even, i want to rebuild that options list, how do I wipe the existing options parameters in order to add new ones? Is that even possible?
Hello! 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! Hi all, I have table in Javascript and it has addrow, deleterow, submit, and functions. when i click it automatically adds new row and it has select option to choose some of them for ex. in added two rows and one of drop down combox i chose Motherboard Asus and from other i chose Motherboard Gigabyte.

Here is my code.. PHP Code: function removeCats() { // Set selected category list var sel_cats = document.getElementById('cat_sel'); for (i = sel_cats.length-1; i >= 0; i--) { // Check if the cat is selected if (sel_cats.childNodes[i].selected == true) { // Remove the category sel_cats.removeChild(sel_cats.childNodes[i]); } } } Thanks again guys! *Edit: I thread title should probably be "Initialize indices..."* I've done quite a bit of research but couldn't find what I need to know so here I am. I have some javascript generated by php that reads a configuration file to add options to a select menu. This is somewhat irrelevant but... these options are removed from the menu when clicked and data related to the option is shown on the page... and the option gets re-added when the data is closed. I need the option to go back in the correct place/order in the select menu... which wouldn't be a problem if I could initialize the indices of the menu's options. They need to be initialized because when the page is created, saved settings are read and certain options are not shown in the list because they may already be shown according to the settings... meaning... since browsers automatically increment the indices of the options by 1 (starting at 0), if data is closed that was initially open and therefore not in the select menu at first... the key/index associated with that data will likely not match the correct menu order. Code: <script type="text/javascript">
function addOptionToSelect(selectID,index,offset,val,txt) {
var elSel = document.getElementById(selectID);
elSel.options[index+offset].value = val;
elSel.options[index+offset].text = txt;
}
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
<?php
foreach ($props as $k => $prop) {
if (!in_array($prop, $_SESSION['crProps'])) {
?>
addLoadEvent(addOptionToSelect('propertySelect',<?php echo $k; ?>,1,'?p=<?php echo $prop; ?>&k=<?php echo $k; ?>','<?php echo $prop; ?>'));
<?php
}
}
?>
</script>
For example, suppose I have the following potential data sets: a,b,c,d,e,f In the config file that helps create the page, suppose it is something like: <Default>0:a|2:c|3:d</Default> (FYI: I've designed it so that the data set names/options are separated by the pipe character ("|") and their corresponding index is the number to the left of the colon.) Then the select menu that is initially generated would be something like: (Every other data set name except for what is already open by default.) <select id="bleh"> <option value="b">b <option value="e">e <option value="f">f </select> And by default, browsers would assign the indices like so: (skipping getElementById and all that...) select.options[0].value = b select.options[1].value = e select.options[2].value = f Whereas, I need it to be initialized like this: select.options[1].value = b select.options[4].value = e select.options[5].value = f So that when the data sets initially open are closed (a, c, or d)... they get put in the correct position in the list. I just thought of something... it's a little inefficient (OCD lol) but it should work and at worst would only cost a couple of milliseconds of processing time. A solution to this problem might be to load the menu with all options so that their indices are correct... and remove the defaults afterward. I'll try it. Dear all, background information: I did code a timesheet management system for my company with PHP where the user has to submit time entries and has an online form with several start and end times. The start and end times are all simple HTML select option dropdowns. I want that the first End time selection will be the next start time selection. Basically a simple dependency of the dropdown. My approach was that I want to solve this with JavaScript. In my php code I am echoing the following (in this select the end times are the values): echo "<select class='normal' name='$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. |
