JavaScript - Building A Dynamic Select Menu From Values Selected In Other Fields
Similar TutorialsHey guys..... I've built a tool where users can search for something & the results show up in a select list as selectable options..... sometimes the results can take a few seconds to load depending on how many results there are... so I was attempting to show some "Results are loading" text when they search, & then hide it when they are displayed. However for some reason it's not working correctly...... both commands don't appear to work until the select list options have loaded & hence rendering them redundant.... I have tried putting them inside separate functions but no change in the behavior. What basically happens is I press the button to search & it searches & once the results show up so does the loading text.... however if I include the hide text command then the text doesn't show at all as it's hidden as soon as it's shown. Here is the code I am using.. PHP Code: function searchCats(text) { // Set URL for ajax request var url = 'search_cats.php?search_text='+text; // Set up element we're modifying var results = document.getElementById('cat_list'); // Trim string text.replace(/^ss*/, '').replace(/ss*$/, ''); if (text.length < 3) { alert('Please enter a search string more than 2 characters.'); return; } // Send the request, giving it an anonymous function that acts as the oncomplete event ajaxRequest(url, (function(ajaxResponse) { /* Deal with results */ // First we remove all current childs while(results.hasChildNodes()) { while (results.childNodes.length >= 1) { results.removeChild(results.firstChild); } } if (ajaxResponse == '') { // Display no results text document.getElementById('no_results').style.display='block'; } else { // Hide no results text document.getElementById('no_results').style.display='none'; // Display loading text document.getElementById('loading_results').style.display='block'; // Check for occurence of cat seperator (if not there then we know we only have one results) var sep_found = ajaxResponse.indexOf('!@!'); if (sep_found === -1) { // One result only // Seperate ID & cat name var parts = ajaxResponse.split('^@^'); // Create option element var option = document.createElement('option'); // Add attribute option.setAttribute('value', parts[0]); // Create text node var textNode = document.createTextNode(parts[1]); // Append text node to option element option.appendChild(textNode); // Now append option element to select list results.appendChild(option); } else { // Seperate cat data var cats = ajaxResponse.split('!@!'); // Loop through cat data for(i = 0; i < cats.length; i++) { // Seperate ID & cat name var parts = cats[i].split('^@^'); // Create option element var option = document.createElement('option'); // Add attribute option.setAttribute('value', parts[0]); // Create text node var textNode = document.createTextNode(parts[1]); // Append text node to option element option.appendChild(textNode); // Now append option element to select list results.appendChild(option); } } } })); // Hide loading text document.getElementById('loading_results').style.display='none'; } Thanks guys! 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 When first loading the page, I want the default select box value to be showing, and change when they select a different value. It works perfect when I select any value, but it's blank on load. I've attached screenshots showing. How can I get it default selected to show "Please Select a Character Class to view more information." Code: <script type = "text/javascript">
function showDetails(which) {
var d = document.getElementById("classDescription");
var s = which.value;
if (s == "Enchantress") {d.innerHTML = "<b>Enchantress</b><br />This character is a magic user. You are weak with attacks, but powerful with magic."}
if (s == "Knight") {d.innerHTML = "<b>Knight</b><br />This character is a physical user. You are powerful with attacks, but weak against magic."}
if (s == "Archer") {d.innerHTML = "<b>Archer</b><br />This character is a unique user. You can attack twice, but can't equip shields."}
if (s == "Thief") {d.innerHTML = "<b>Thief</b><br />This character lurks in the shadows. He is crafty, weak attacks, decent magic."}
if (s == "") {d.innerHTML = "Please Select a Character Class to view more information."}
}
</script>
Code: <select name="Character_Class" id="CharClass" onchange="showDetails(this)">
<option value="" selected="selected">Choose a Class</option>
<option value="Enchantress">Enchantress</option>
<option value="Knight">Knight</option>
<option value="Archer">Archer</option>
<option value="Thief">Thief</option>
</select>
Code: <li><div id="classDescription"></div></li> i have a script which i found on the internet. i modify that script according to my needs. what is in that script is there are three form fields with two buttons. one button is "Give me more fields" clicking on this button will give you more fields. and second button is submit so the data goes to server side and will be added to db. the problem is when i click give me more fields it gives me three more fields which is right but when i fill all these fields and click submit button it adds to the db but the data in the first three fields adds in the one row and the other three fields data adds in separate row which is not fine for me. so how can i do this so all the data will be added to only one row. here is js code Code: var counter = 0;
//Start a counter. Yes, at 0
function add_phone() {
counter++;
// I find it easier to start the incrementing of the counter here.
var newFields = document.getElementById('addQualification').cloneNode(true);
newFields.id = '';
newFields.style.display = 'block';
var newField = newFields.childNodes;
for (var i=0;i<newField.length;i++) {
var theName = newField[i].name
if (theName)
newField[i].name = theName + counter;
// This will change the 'name' field by adding an auto incrementing number at the end. This is important.
}
var insertHere = document.getElementById('addQualification');
// Inside the getElementById brackets is the name of the div class you will use.
insertHere.parentNode.insertBefore(newFields,insertHere);
}
here is my form Code: <form name="addAQualification" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
<fieldset>
<div id="phone">
Degree:
<input type="text" name="degree_0" value="" /><br>

</div>
<input type="button" id="add_phone()" onclick="add_phone()" value="Give me more fields!" /><br>
<input type="submit" name="submit" value="submit" />
</fieldset>
</form>
here is my php Code: <?php
if(isset($_POST['submit']))
//This checks to make sure submit was clicked
{
echo "You clicked submit!<br>";
echo "Here is your data<br>";
echo "<br>";
if ($_POST['cgpa_0'])
//This checks that the proper field has data
{
$continue = FALSE;
$i = 0;
while ($continue == FALSE)
{
if (isset($_POST['degree_'.$i]))
//This looks for an entry after 0 and increments
{
echo $_POST['degree_'.$i] . " = " . $_POST['cgpa_'.$i] . "<br>";
//Echoing the data
$degree1 = $_POST['degree_'.$i];
$cgpa1 = $_POST['cgpa_'.$i];

hi i am newbie to js please help me like a newbie thanks. i want to make a form. the form will have three text fields and with two buttons. what i want with this form is when the user enters the first three fields and if he wants to add more then he will click on add more button and on the same page three more fields will appear below the first three fields. the user will then enter these three fields then if he wants to add more then he will click on add more button. so three more fields will appear below the first six fields. user will enter these fields. he will be allowed to enter upto eight or less than eight times. once he finishes with this then he will click the second button to insert this data into db. hi guys kindly assist in this i have the code below used to generate additional dynamic fields how can i save data entered in mysql??? <HTML> <HEAD> <TITLE>New Task</TITLE> <link rel="stylesheet" href="style1.css" type="text/css"/> <meta http-equiv="Content-Script-Type" content="text/javascript"> <SCRIPT language="javascript"> function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length; var row = table.insertRow(rowCount); var colCount = table.rows[0].cells.length; for(var i=0; i<colCount; i++) { var newcell = row.insertCell(i); newcell.innerHTML = rowCount + 1; newcell.innerHTML = table.rows[0].cells[i].innerHTML; //alert(newcell.childNodes); switch(newcell.childNodes[0].type) { case "text": newcell.childNodes[0].value = ""; break; case "checkbox": newcell.childNodes[0].checked = false; break; case "select-one": newcell.childNodes[0].selectedIndex = 0; break; } } } function deleteRow(tableID) { try { var table = document.getElementById(tableID); var rowCount = table.rows.length; for(var i=0; i<rowCount; i++) { var row = table.rows[i]; var chkbox = row.cells[0].childNodes[0]; if(null != chkbox && true == chkbox.checked) { if(rowCount <= 1) { alert("Cannot delete all the rows."); break; } table.deleteRow(i); rowCount--; i--; } } }catch(e) { alert(e); } } </SCRIPT> </HEAD> <BODY> <br> <br> <h2>INPUT NEW TASK</h2> <table border="1" width="100%"> <tr> <td> <fieldset> <legend></legend> <table border="0" width="100%"> <tr> <td>User:</td> <td><input type="text" size="20" name=""disabled></td> <td>Start Date:</td> <td><input type="text" size="20"></td> </tr> <tr> <td>Client name:</td> <td><select name=""></select></td> <td>Process</td> <td><select name=""></select></td> <td>Day?</td> <td><input type="text" size="5"></td> </tr> </table> </fieldset> <fieldset> <legend>Tasks</legend> <table border="0" width="100%"> <th width="5">select</th><th width="5">No</th><th width="150">Task</th><th width="400">Description</th><th width="100">Start Time</th> <th width="100">End Time</th><th width="100">Worked hrs</th><th width="90">Action</th> <tr> </table> <TABLE id="dataTable" width="100%" border="1"> <TD><INPUT type="checkbox" name="chk"/></TD> <td width="5"><input type="text" size="5"name=""disabled></td> <td width="150"><select name=""></select></td> <td><textarea rows="2" cols="30"></textarea></td> <td><input type="text" size="10"name=""></td> <td><input type="text" size="10"name=""enabled></td> <td><input type="text" size="10"name=""disabled></td> <td><input type="button"type="button" value="+" onclick="addRow('dataTable')"></td> <td><input type="button"type="button" value="-" onclick="deleteRow('dataTable')"></td> </tr> </table> </fieldset> <table border="0" width="100%"> <tr> <td width="122"><input type="button" value="SAVE"></td> <td></td> <td> </td> <td> </td> <td> </td> </tr> </table> </td> </tr> </table> </BODY> </HTML> I am using a script that duplicates a fieldset and an onBlur event that updates a sub total when you enter a value into 3 fields in the set but I am having one glitch that I can not figure out and would appreciate any insight you can provide. Here is the trouble: The duplication of the fieldset works great. I have another script which is creating a sum ("sum") of the fields named "unitPrice" in the original fieldset. When I duplicate the fieldset that has the new "unitPrice" fields they do not get calculated into that sum. I am sure the "unitPrice" fields are being renamed in the new fieldset but what name would I use and how do I write it into the calculation so that the sub total ("sum") is updated with all of the "unitPrice" fields?

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 html like this Code: <form>
<select name="otype[]" class="txtText" id="otype[]">
<option value="Processing">Processing</option>
<option value="Shipped">Shipped</option>
</select>
some code......
<select name="otype[]" class="txtText" id="otype[]">
<option value="Processing">Processing</option>
<option value="Shipped">Shipped</option>
</select>
some code.......
<select name="otype[]" class="txtText" id="otype[]">
<option value="Processing">Processing</option>
<option value="Shipped">Shipped</option>
</select>
I need to change all select lists options to "Shipped" if admin clicks on "Shipped" on top of the page and "Processing" if customer clicks on "Processing" link (<a href="javascript:select_processing()">Processing</a>) Can somebody help me in doing so? ok so i need help.... I need to create a page containing five image tags, two buttons, a <select> and a <textarea>. The images tags will each contain a picture of one of six possible outcomes for the dice portraying the numbers one through six.. The first button: When the user clicks on the button, all dice are rolled once. For each die when rolled, the src of its image tag is replaced with a random one of six possible pictures -- each picture being chosen with equal probability (1/6).... I HAVE THIS DONE The select: The user may select any of the numbers one through six. Whenever a picture is clicked upon, then that die takes on the value shown inside the <select>..... THIS IS WHAT I NEED HELP WITH The textarea: Results of the dice rolls should be kept as a running log (a cumulative history) in a textarea at the bottom of the page. With each roll (initiated by the click of the button), we should be able to see the complete history of all current and previous dice rolls. You need not consider changes brought about clicks on individual dice in conjunction with the <select>....I HAVE THIS DONE The second button: A button below the textarea, should allow the user to obtain a report (overwriting the current contents of the log in the textarea) which tabulates the frequency of each of the six outcomes plotted separately for each of the dice. The frequency tabulation should show how often each die was rolled, as consistent with the data stored in the log....

The problem i'm having is that I use the combo boxes to allow users to submit a DB search request using GET Form and I need to have the submitted parameters "selected" when the search result page loads. I've searched all over the internet and I can't seem to find a usable solution so any help would be GREATLY appreciated. Thanks! If you need more information, lemme know! Nick My goal is that when I click on the submit button, I just want to display an alert box with the values selected, and also look at this in the console.log. Can anyone help me? Thanks.

Hello all, I am having a problem, and since I am quite new in the Javascript code I hope somebody can help me here. This is my current code: Code: <select class="Form" name="opties"> <option value="AAA">AAA</option> <option value="BBB">BBB</option> <option value="SLX" selected>Selecteer optie</option> </select> Now my intention is the following: When the option with value SLX gets selected it needs to get a special css style. It is not a problem to give the option this style in the list itself, but once selected it always changes to the original style (standard font and color) in Chrome and Mozilla. Now I searched on the net and sometimes I find things like this: Code: function displayOption(divName)
{
document.getElementById(divName).innerText=document.form1.select1.options[document.form1.select1.selectedIndex].value;
}
<select class="Form" name="opties" onChange="displayOption('div1');">
<option value="AAA">AAA</option>
<option value="BBB">BBB</option>
<option value="SLX" selected>Selecteer optie</option>
</select>
But I suppose this always changes the style of the selected item? It only needs to change when the option SLX is chosen... Anyone knows how to solve this problem? total score from selected drop down values Hello friends the following is the code i am using without success Code: var numQuestn = 6;

i am not able to find the error Please help me Thank you in advance Hey javascript newbie, Im trying to figure out how to add different radio if its selected or not example: Radio_Button1 value="5": Selected Radio_Button2 value="15": Not Selected Radio_Button3 value="25": Selected Radio_Button4 value="35": Selected var addingitup = ??? and im lost???? I have a form which contains a few drop down lists. The contents of the dropdown lists are dependent on each other and are populated via php scripts which are called each time a selection is made or changed by the user. When the view results button is clicked in the form I need the user to be directed to a specific page based on the selections they have made. The url of the page they need to be directed to is really based on what has been chosen in the first dropdown. The subsequent dropdowns form variables that I need to be sent to the page so that the data the user sees on that page is relevant. ie if the user has chosen bikes then a specific manufacturer then a specific price range the page they will be sent to will be the bike.php page with all the manufacturer specific bikes in their chosen price range visible. Can anyone tell me the best way to go about doing this please? I had thought about using the php header script along with an if statement but how do I then go about getting the variables sent to the page to be recognised? Would I be better looking at the window.location in js to do this? Any help and advice would be greatly appreciated on this. I can post the code for the form if that makes any difference. I am very very new to programming and trying to create a web interface for a model. The user needs to be able to add as many compounds as they want and add a variable number of subgroups for each compound. Also, each input needs a distinct name. I have tried adapting someone else code to add/remove form inputs but am not having any luck creating subgroups. below is my code Code: <html>
<head>
<title>form</title>
<content="text/html"; />
<script type="text/javascript">
<!--
window.onload = function () {
if (self.init)
init();
}
var counter = 0;
var counter1 = 0;

document.getElementById('moreFields1').onclick = moreFields1;
moreFields();
moreFields1();
}
function moreFields() {
counter++;
var newFields = document.getElementById('readcomp').cloneNode(true);

any help would be appreciated. thanks I have a form that only shows the submit (update) buttons if the value select field beside it is changed. But what is someone has JS disabled, how can I enable them? Code: <select title="3553" name="3553" onchange="JavaScript:document.cart.add3553.disabled=false;"> Am integrating a Barclays epdq shopping cart into an existing website, part of the regulations with this system is that you can only submit from one 'allowed url'. To enable access from multiple url's I need to create a 'jump page'. This needs to be a simple page that takes any variables posted to it and re-posts them (onload) onto the epdq shopping cart. The problem is I am unable to populate the form dynamically and submit onload. I have tested and it all works fine if hardcoded. Is it possible to submit a dynamically generated form using javascript? PHP Code: foreach ($_POST as $name => $value){ $newVars .= '<INPUT value="' . $value . '" name="' . $name .'" type="hidden" />'; } Code: <html> <head></head> <body onLoad="document.epdqformer.submit();"> <FORM name="epdqformer" id="epdqformer" action="https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdq.e" method="POST"> PHP Code: Hiya! I'm a total JS beginner, so any help is appreciated. I've created the simple select box below that will "onchange" when an item is selected. I'm trying to apply the "selected" or "selected="selected" attribute to items that are chosen from the menu. Example: The goal is to show " <option value="/1" selected="selected"> " when page "/1" is chosen and to show <option value="/1"> when /1 is not the current page. I've follow a few simple tutorials with no luck and even tried php conditionals to trigger the "selected" attribute with no luck. Any feedback is GREATLY appreciated, thank you! Code: <form name="guideform" method="get"> <select class="wptdb_jumpbar_select" name="mymenu" onChange="window.location=document.guideform.mymenu.options[document.guideform.mymenu.selectedIndex].value"> <option value="/1">Home Page #1</option> <option value="/2">Home Page #2</option> <option value="/3">Home Page #3</option> <option value="/4">Home Page #4</option> </select> </form> |
