JavaScript - Changing Hidden Field Value Based On Selected Option.
Hi,
Is there anyone who could help me figure out how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work. Any help would be greatly appreciated, thanks. <script language="JavaScript"> function changelist() { //here we assign the value of the hidden input to x x=eval(document.getElementByName("SelectLists[40]"); if(document.getElementById("SelectLists[40]").selected=true x=SelectLists[40] else(document.getElementById("SelectLists[41]").selected=true x=SelectLists[41] else(document.getElementById("SelectLists[42]").selected=true x=SelectLists[42] //now we assign the new value to the input document.getElementById("theHiddenInput").name=x; //and now we test alert(document.getElementById("theHiddenInput").name) } </script> <input type="hidden" id="theHiddenInput" name="SelectLists[40]" value="Yes"> <select class="inpBox" style="width: 287px" name='mailinglist' id="lists" onchange="changelist()"> <option value="SelectLists[40]" name="SelectLists[40]" id="SelectLists[40]">MyList</option> <option value="SelectLists[41]" name="SelectLists[41]" id="SelectLists[41]">testlist</option> <option value="SelectLists[42]" name="SelectLists[42]" id="SelectLists[42]">testlist2</option> Similar TutorialsI've inherited this piece and now I'm suppose to add to it. Its basic function currently is when the "Other" option is selected, a hidden text field shows. Now, I need to add when "Athletics" is selected, another hidden select group will show. I've set up the new Select group already, but not sure how to incorporate it into the already existing script. I've been researching for two days, and hopefully this form will be helpful. Code: <select id="Program" name="Program" size="1" onchange="
$other = document.getElementById('other_program').style;
$invoice = document.getElementById('invoice');
if (selectedIndex==6) {
$other.visibility='visible';
if ($invoice.value == 'General Fund') $invoice.value='';
} else {
$other.visibility='hidden';
if (selectedIndex==1) {
$invoice.value='Renegade Fund';
} else {
$invoice.value='Please Specify';
}
}
">
<option selected="selected" value="Not Selected"> - - Select One - - </option>
<option value="Athletics">Athletics</option>
<option value="Drum Line">Drum Line</option>
<option value="Renegade Fund">Renegade Fund</option>
<option value="General Scholarships">General Scholarships</option>
<option value="President's Circle">President's Circle</option>
<option value="Other">Other</option>
</select>
<span id="other_program"><input type="text" id="invoice" name="invoice" size="15" /></span>
<!-- the following is the new select group ive set up
<span id="alumni">
<select id="select-alumni" name="select-alumni" size="1">
<option selected="selected" value="Not Selected">Yes or No</option>
<option value="Yes-alumni">Yes</option>
<option value="Not-alumni">No</option>
</select>
</span>

Hello, I am hoping someone can help me with following search form. As you can see I have created a form but I don't know how to fix the coding so when a user select a category it will add a different hidden filed for that option for example: When the user selects category "Men" the hidden filed Code: <INPUT TYPE="HIDDEN" NAME="REFERRER" VALUE="http://men.com/acatalog/"> will be added and when the user selects category "Kids" the hidden filed Code: <INPUT TYPE="HIDDEN" NAME="REFERRER" VALUE="http://kids.com/acatalog/"> will be added and so on... Here is my form coding I am using: Code: <form name="simplesearch" method="get" action="" onsubmit="ssite=document.getElementById('sitelist');this.action=ssite.options[ssite.selectedIndex].value;return true;">
<input type="hidden" name="page" value="search" />
<input type="hidden" name="PR" value="-1" />
<input type="hidden" name="TB" value="A" />
<input type="hidden" name="NOLOGIN" value="1" /><input align="top" class="main_search_box" name="SS" type="text" value="search for ..." onfocus="this.value='';">
Search within:
<select id="sitelist">
<option value="">Select Catagory</option>
<option value="http://kids.com/cgi-bin/ss000001.pl">kids</option>
<option value="http://men.com/cgi-bin/ss000001.pl">men</option>
<option value="http://women.com/cgi-bin/ss000001.pl">women</option>
</select><input type="submit" class="button" name="ACTION" value="Go!">
</form>
Also I have one more question how do I make the "Select Catagory" a Must Choose and if not chosen to give message that say"Please Select a Category" Thank you in advance for any help you can give me... I am a bigginer so please go easy on me I'm taking a beginning javascript class and have been trying to figure out one last part of a homework assignment and am just not seeing how to work it out. Any help is greatly appreciated! What I'm having trouble with is doing the text verification. When a user selects an option from the select list they then need to type in the text area given. If the user doesn't type the word selected in the list then an error message should appear under the text area. If you look at my code you'll see that I have the text_check() function doing the verification. I can get it to work when there is only one option but once I add the other two it stops working. I've tried if... else and other variations, but can't seem to nail it down. Thanks! Code: function select_function()

I have an options list that is generated from a database. It currently has ~125 options in it. I've received the request that the user be able to either enter the corresponding number or select the option from the list. How can I update the "selected" attribute in the options list based on a number that may be entered in another text entry box? Hi, I'm new to JavaScript. I'm trying to create my form in such a way that if 'Premium' is selected, a the text box with label 'membership no' is displayed and if 'bronze' is select, the drop-down list 'sponsor' is displayed instead....here's what my form looks like... PHP Code: <form id="form1" name="form1" method="post" action=""> <p> <label for="select">Membership:</label> <br /> <select name="select" id="select"> <option value="Premium" selected="selected">premium</option> <option value="Bronze">bronze</option> </select> </p> <p>Membership No:<br /> <input type="text" name="textfield" id="textfield" /> </p> OR<br /> Sponsor: <br /> <select name="select2" id="select2"> <option value="329">329</option> <option value="234">234</option> </select> </form> appreciate the help Hi folks. Looking to see if anyone could tell me where I'm going wrong with this script... I'm trying to have a field automatically filled with the day of the week ("Monday", "Tuesday", "Wednesday" and so on), upon the user selecting a date from the datepicker jQuery. If this isn't clear, I'll clarify further down the page. Here is the script: Code: <script type="text/javascript">
jQuery(document).ready(function($){
$('input[name="item_meta[428]"]').change(function(){
var d = $('input[name="item_meta[428]"]').val();
var n = new Date(d).getDay();
if(n == 0)
val v = 'Sunday';
else if(n == 1)
val v = 'Monday';
else if(n == 2)
val v = 'Tuesday';
else if(n == 3)
val v = 'Wednesday';
else if(n == 4)
val v = 'Thursday';
else if(n == 5)
val v = 'Friday';
else if(n == 6)
val v = 'Saturday';
$('input[name="item_meta[429]"]').val(v).change();
});
});
</script>
I'm basically trying to say, if the user selected today (15/05/2012) in the field 428 it would fill the field 429 with "Tuesday". Again, if the user selected 18/05/2012 in the field 428 then it would automatically fill field 429 with "Friday". It's being done to work in conjunction with a wordpress plugin called Formidable Pro hence the item_meta[428] etc. Any assistance would be greatly appreciated. Sam. I have a select box with a few options. When the page loads I need to get the selected option in this select box and alert its inner text. Yet everything I try out on the net that should work wont work in IE, all other browser its fine. Please can someone show me the TRUE and correct way to get the inner text of a option from a select box in IE? Thanks! Hello everybody, I have a javascript adding new options to a drop down select menu getting the information from the database. The code is as written below: Code: function setOptions1() {
var selbox2 = document.egitimgiris.alttipID;
selbox2.options.length = 0;
selbox2.options[selbox2.options.length] = new Option('Option1','22')
selbox2.options[selbox2.options.length] = new Option('Option2','23')
selbox2.options[selbox2.options.length] = new Option('Option3','24')
selbox2.options[selbox2.options.length] = new Option('Option4','25')
}
I want one of them to be added as selected. I will put an "if" check and if it the value of the option and the value in the database is equal I want that option to be added as "selected". Is this possible? If yes, how? Please help. Thanks and regards telmessos I have a simple form with an options drop down box: Code: <form method="POST" name="form"> <select autocomplete="off" id="input" name="input" onchange="this.form.submit();goHere();"> <option>Choose...</option> <option>Question1</option> <option>Question2</option> <option>Question3</option> </select> I wish to identify the option chosen in the function but not by its value, by its position: Code: <script>
function goHere(){
var s = document.getElementById("input");
if (s.selectedIndex == -1) return;
var u = s.form.elements[i];
alert(u);
</script>
I was hoping that variable "u" would be either 0, 1, 2, or 3. How can I get a variable to alert me the position of the selected option in the form? I think it is elements[i]. I couldn't think of a way to explain my idea thoroughly, but I'm learning javascript and I have an html <select> form selected by using getElementById. Now, how do I access the data within the option tags to write to a variable? I know there are many simple ways of making it so that the value of the options are the html color name rather than hex code, but I'm doing this to learn javascript. I have experience with ruby (ok, not THAT much, but I understand the concepts). Anyway's the code explains my problem much better, so here it is: Code: <body>
<form action= "">
<fieldset>
<select id="selColor">
<option value="FFFFFF">White</option>
<option value="#A9A9A9">Gray</option>
<option value="#000000">Black</option>
<option value="#FF0000">Red</option>
<option value="#FFA500">Orange</option>
<option value="FFFF00">Yellow</option>
<option value="#9ACD32">Green</option>
<option value="#0000FF">Blue</option>
<option value="#4B0082">Indigo</option>
<option value="#9400D3">Violet</option>
</select>
<input type="button"
value="Change Color"
onclick="changeColor()" />
</fieldset>
</form>
<script type="text/javascript">
//<![CDATA[
function changeColor() {
var selColor = document.getElementById("selColor")
var color = selColor.value
var colorid =
if (confirm("would you like to change color to "+colorid+"?")) {
document.body.style.backgroundColor = color
}
}
//]]>
</script>
</body>
I haven't initialized var colorid, but I'm trying to set it to either of the highlighted parts of the following piece of my code. <option id=" white " value="FFFFFF"> White </option> I want to access that part of the option tags of the element that the user selects. So, without changing the hex values to the color equivalent, how do I access the name of the selected option tag? ( I could make an if/switch statement to translate the hex color into a name and put it into the variable, but I would like to know how to do what I'm asking in case I run into a similair problem.) I have a dropdown box with 2 options: Free or Upgraded I need to do 2 separate things depending on which one is chosen. If Free, then set the value in fourth text field to 9999 else, set value in Fourth field to 5555. Code: <head>
<script type="text/javascript">
function calculate()
{
var myLevel = eval(document.earningsform.level.value)
var memberType = eval(document.earningsform.type.value)
if(memberType==free){
document.earningsform.fourth.value = 9999;
}
else{
document.earningsform.fourth.value = 5555;
}
</script>
</head>

I have a text field, call it income, that when the input is > 0 I need to dynamically show the next text box, and if it is blank hide the next text box.

Cheers, Shashikant Shinde i'm working with a city select option, a hotel select option & an iframe. the hotel select option is populated depending on the chosen city which then updates the iframe src. this is all working fine. the trouble im having is that when the page is refreshed, normal f5 way, the hotel option changes whereas the city option & the iframe src remains the same?? this problem does not occur on a force refresh via control + f5 as then both select options & iframe src revert to their original state. I don't want the city option to change upon a normal page refresh. how do I go about this? below are the city, hotel select options & iframe Code: <form name="hotelslist" id="hotelslist">
<select id="cities" name="cities" onChange="hotel_list(hotelslist.cities.selectedIndex);loadHotel();">
<option value="Baddeck">Baddeck</option>
<option value="Banff">Banff</option>

can some one please advise on a cross browser solution? thanks in advance. Omar. I have a form that has a checkbox that I want to base a hidden value on. If the checkbox is checked I want the hidden value to be 25. If not checked, I want the value to be 0. I am working with code someone else has written and I am fairly new to javascript and cannot get it to work. Here is the code on the form: <code> <td><input type="checkbox" name="binderdiscount" value="Yes" <?php /*?><?php if ($pgdata['binderdiscount']=='Yes') echo 'checked'; ?><?php */?> />I do not need a book;</td> <input type="hidden" name="binder_discount" value="0"> </code> and then in a separate page is all the javascript to process the form. I have this, but it is not working. <code> if(getControlValue(form.binderdiscount)==="Yes") {form.binder_discount.value=25;} </code> As I said, i am really new to javascript and I am working with someone else's code. All the research I have done has just confused me more about why it is not working. Any help would be greatly appreciated. I have a simple script connect to a radio button. Based on which option, the matching div appears with a text box - and one with a radio button. If they change their mind and click another radio button, it'll switch to the new div, but keep the content in the old. How do I clear that out? I looked for a snippet, but they're all for clearing default text in a field when you click it. I want something a little different. Here's what I'm using: Code: <script>
$(document).ready(function() {
$("div.desc").hide();
$("input[name$='hear']").click(function() {
var test = $(this).val();
$("div.desc").hide();
$("#" + test).show();
});
});
</script>
<input type="radio" name="hear" value="dcranch"> DC Ranch Community <br />
<input type="radio" name="hear" value="friend"> From a friend <br />
<div style="display: none;" id="dcranch" class="desc"> <input type="checkbox" value="Yes" name="resident" /> If so, are you a DC Ranch resident? )</div><br />
<div style="display: none;" id="friend" class="desc"> Name? <input type="text" name="how1" /></div><br />
