JavaScript - Select A Page

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.

I'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" . "tarea>"; ?>				
	</div>
	
	<div style="padding-bottom: 1em;"><input name="submit" type="submit" value="Submit">
	</div>
</form>


</div>

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">

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

Hey Guys
When a user changes the select list called "reason_code_master" I need the uodatecodes() function to update all the other select list with the id of "reason_codes" with the same . How can I do this.


<select size='1' onchange="updatecodes()" name='reason_code_master'>
<option value='' > - SET REASON - </option>
<option value='BROKEN' >BROKEN</option>
<option value='ENTERED' >ENTERED</option>
<option value='SHORT' >SHORT</option>
</select>

<select size='1' name='reason_codes' id='reason_codes'>
<option value='' > - SET REASON - </option>
<option value='BROKEN' >BROKEN</option>
<option value='ENTERED' >ENTERED</option>
<option value='SHORT' >SHORT</option>
</select>
<select size='1' name='reason_codes' id='reason_codes'>
<option value='' > - SET REASON - </option>
<option value='BROKEN' >BROKEN</option>
<option value='ENTERED' >ENTERED</option>
<option value='SHORT' >SHORT</option>
</select>
<select size='1' name='reason_codes' id='reason_codes'>
<option value='' > - SET REASON - </option>
<option value='BROKEN' >BROKEN</option>
<option value='ENTERED' >ENTERED</option>
<option value='SHORT' >SHORT</option>
</select>
<select size='1' name='reason_codes' id='reason_codes'>
<option value='' > - SET REASON - </option>
<option value='BROKEN' >BROKEN</option>
<option value='ENTERED' >ENTERED</option>
<option value='SHORT' >SHORT</option>
</select>

Ok so I'm making this form which when a selection is made in one box it will run through the javascript(function getMgmtHours), and update the div(mgmthours). Then another box shows up allowing another selection to be made which runs through the javascript(function getDays) and updates another div(mgmtdate). My problem is that when I use the second box to run through javascript, it overwrites what shows up in the first div (mgmthours) when it should be updating a different div (mgmtdate). Any ideas what I can do to get it update the relevant div and not overwrite the other one?

Here is part of the javascript I have in my page head:

Code:

function getMgmtHours(str)
{
if (str=="")
  {
  document.getElementById("mgmthours").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {
   // code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("mgmthours").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getmgmthours.php?dist="+str,true);
xmlhttp.send();
}

function getDays(str)
{
if (str=="")
  {
  document.getElementById("mgmtdate").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {
   // code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("mgmtdate").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getdates.php?sunday="+str,true);
xmlhttp.send();
}

Here is the HTML/PHP portion being used:
PHP Code:
echo "<p>";
echo "Submit hours:";
echo "<form>";
echo "<select name='district' onchange='getMgmtHours(this.value)'>";
echo "<option value=''>Select a district:</option>
<option value='1'>1</option>
<option value='3'>3</option>
<option value='4'>4</option>";
echo "</select>";
echo "</form>";
echo "</p>"

echo "<p>";
echo "<form action='./hours.php' method='post' onSubmit='return checkMgmtHours'>";
echo "Weekending Day: ";
echo "<select name='weekending' onchange='getDays(this.value)'>";
echo "<option value=''>Choose a Date:</option>";

while ($week < 32) {
    $nextsunday = strtotime("next Sunday");
    
    if ($week > 0) { $timestamp = strtotime("-" . $week . " week", $nextsunday); } else { $timestamp = $nextsunday;}
    
    $weekending = date('M. d, Y', $timestamp);
    echo "<option value='" . $weekending . "'>" . $weekending . "</option>";
    $week = $week + 1;
}

echo "</select>";

echo "<div id='mgmtdate' />";
echo "<div id='mgmthours' />";
echo "</p>"; 


Edit: Also, after getMgmtHours() runs, I can still use both getDays and getMgmtHours, howeer once I used getDays, I am no longer able to use getMgmtHours w/o refreshing the page.

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.

I've got some directory list boxes on the site I'm working on. I made them big and fixed rather than drop-down so they're easier to use in this context. But I had to enable the "multiple" attribute to make that work. The site has no provision for multiple selections so it's a tad annoying when the search function selects more than one name in the list.

It doesn't really affect the site's operation but it could be confusing to some people. Is there a way to make the listbox show multiple selections without allowing multiple selections? Thanks for any help.

<select onchange="display.apply(this, this.value.split(','))" multiple="multiple" id="People" name="People" style="border-style: none; height:244px; width:220px; margin-bottom: 15px;">
<option>Loading</option>
</select>

Hi All,

First time user of this forum and need some help please. I have a webpage where I am displaying checkboxes next to rows. I would like to have one checkbox which will select everything. I have written this code but it does'nt seem to work. Can someone advice as to whats wrong here.

The HTML code for checkAll checkbox is:
Code:

<thead>
<tr>
<th>Select All <input type='checkbox' name='checkall' onclick='checkedAll(frm1);'>  </th>

The HTML code for each checbox is :
Code:

<form id="frm1" />
            <tbody>
			<?php
			foreach ($consignment_array as $ct_idx => $consignment)
			{
				$status = $consignment->getStatus();
                $id= $consignment->getId();
				?>
				<tr class="<?php echo "cls" . $status; ?>">
                    <td id="c"> <input type=checkbox id= "1" name="deleteConsignments" onclick="row_color(this)" value= <?php echo $consignment->getId(); ?> /> </td>

The javascript is :
Code:

function checkedAll (frm1) {
    alert("in check all");
    var aa= document.getElementById('frm1');
     if (checked == false)
          {
           checked = true
          }
        else
          {
          checked = false
          }
    for (var i =0; i < aa.elements.length; i++) 
    {
     aa.elements[i].checked = checked;
    }
      }

The problem is that its not even going into the Javacript because I dont get the alert.

Appreciate the help guys.

Thanks.

Hi Guys,

A bit stuck here and was wondering what you guys think.

I have an HTML Select Option with a list of countries. A user saves that page and when he wants to return to the same page later at some point, i would like to populate the countries drop down list with what he entered initially.

Is there an easy way to do this?

Thanks.

All,
If I have the following code:
Code:

<form name="datatoshow" id="datatoshow">
Want to learn more about the sie? Use the drop down menu:<br />
<select name="thingtoshow" onchange="javascript:showvalues(this.datatoshow);">
<option value="home">Home</option>
<option value="help">Help!</option>
<option value="refer">Refer a Friend</option>
</select>		
</form>

This doesn't do anything on the onchange. The code it's supposed to send to is:
Code:

function showvalues(selObj){
alert("it gets here");
var valuetoshow;
valuetoshow = "valuetoshow="+selObj.options[selObj.selectedIndex].value;
alert(valuetoshow);
makePOSTRequest('showhome.php', valuetoshow);
}

This is in external js file. For some reason it doesn't send it and the alert never gets triggered.

Thanks.
