JavaScript - How To Add A Selected Option To A Drop Down Menu
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 Similar TutorialsHi, all New here and hoping you can help. I'm trying to figure out the correct event handler and syntax (and whether or not to use a header script) to pass the selected value from a dropdown menu back to PHP. In a nutshell, here's my process: PHP creates an HTML form containing a drop down menu populated with names and email addresses, email being the option value. This is followed by an input box where the user will select a name from the list, enter an amount into the input box, then submit the whole form with an image button, where this data will be passed back to PHP for insertion into the database. The amount portion works beautifully. I can hit the database every time. On the other hand, I cannot get the name/email selection from the drop down menu to be recognized no matter what I do. It tells me nothing is selected even when it is. Well, that isn't entirely true - the closest I've come was apparently screwing up a portion of the PHP code which generates the form and somehow received a Forbidden error when the form tried to link me to the email address. I've never been so happy to be forbidden - or receive an error - in my life. LOL At least that meant I was finally being heard, even if not in the way I want or need. I've tried onChange, onClick, onSubmit and can't seem to hit the right combo. Here's a look at one scenario of many that I've tried. I'd greatly appreciate it if you could steer me in the right direction! PHP to create form: PHP Code: $data = array('form' => draw_form('customer_dropdown', LINK_TO_ACTION, 'page=' . $_GET['page'] . '&action=newrecord'). html_entity_decode(draw_drop_down_menu('customers_email_address',$customers, $_GET['customer'], 'onSubmit="return dropdown(this.customers_email_address)"') .'<input type="hidden" name="selected_entry" value=""><input type="submit" value="" style="display: none;">')); HTML & Java: Code: <html>

<SCRIPT TYPE="text/javascript">
<!--

{
var myWin, myVal;
myVal = mySel.options[mySel.selectedIndex].value;
if(myVal)
{
if(mySel.form.target)myWin = parent[mySel.form.target];
else myWin = window;
if (! myWin) return true;
myWin.location = myVal;
}
return false;

This is hopefully my last jquery question. I have a slight issue with my buttons and dropdown menu. What happens is lets say user chooses option type "ABCDE" in first dropdown menu and then second dropdown menu chooses the value "4" for the number of answers and then clicks on the buttons "A","B","C" and "E", well if the user then decides to change the option type to "ABC", the buttons "A", "B" and "C" are still selected from the last time they have been selected. What I want is that if the Option Type (OptionDropId) changes, then buttons selected is refreshed so no buttons are selected from the last time they have been selected. This did used to work but when I included my change() event handler in my code which I need, the buttons do not refresh whenever a new dropdown option (OptionDropId) is selected. So I think the edit of the code may need to happen in the code below: Code: $(document).ready(function ()
{
var OptDrop = new Array();
OptDrop.abc = ["",1,2];
OptDrop.abcd = ["",1,2,3];
OptDrop.abcde = ["",1,2,3,4];
OptDrop.trueorfalse = [1];
OptDrop.yesorno = [1];
$("#optionDropId").change(function ()
{
var selectedValue = $(this).val();
$("#numberDropId").html("");
$.each(OptDrop[selectedValue], function (x, y)
{
$("#numberDropId").append($("<option></option>").attr("value", y).html(y));
});
});
$("#optionDropId").change();
});
My code is in JSfiddle, (the second dropdown menu and buttons may not appear in JSFiddle but the code does work properly, I feel it is better displaying code in JSfiddle then in my questions as it will take up a lot of space. If you want to see working version then post code in your web document and it should work). My Code: [click below][1] [1]: http://jsfiddle.net/XZ7um/10/ have a scenario where I show a drop-down-with-few-items in a JSP page, to the user. The length of few options in the drop down is greater than that of the drop down's, hence our requirement is to show the hovered (not selected) option as tooltip for user's convenience. I cannot use the title attribute option as its not compatible with my web browser I have a scenario where I show a drop-down-with-few-items in a JSP page, to the user. The length of few options in the drop down is greater than that of the drop down's, hence our requirement is to show the hovered (not selected) option as tooltip for user's convenience. I am not able to use title attribute for displaying tooltips in my browser. Now the code in http://dossett.org/11/No_onmouseover_for_options_in_IE/ implements a tooltip for multiple select drop down menu.Can you modify the code for single select Hello all, I am currently looking to create a JavaScript menu for a website I am working on. It currently expands and collapses on click. The code in question is pasted below:- menu_status = new Array(); function showHide(theid){ if (document.getElementById) { var switch_id = document.getElementById(theid); if(menu_status[theid] != 'show') { switch_id.className = 'show'; menu_status[theid] = 'show'; }else{ switch_id.className = 'hide'; menu_status[theid] = 'hide'; } } } As you can see, it basically shows and hides the menu (when clicked). I want it to open the menu when clicked and close when another menu is opened. I have looked and have not been able to find a solution into it. Ideally I donot want it to be a long piece of code as I do have a working menu but with many more lines of JavaScript than the one I have posted. I need a solution to it urgently, your help is appreciated. Thanks 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! 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 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>
<body>
<table>
<form action="calculator.php" method="POST" name="earningsform">
<tr>
<td align="center">My Level: </td><td><input type="text" name="level" value="50" size="10"></td><td></td>
</tr>
<tr>
<td align="center">Member Type: </td><td>
<select name="type">
<option value="upgraded" name="upgraded" selected="selected">Upgraded</option>
<option value="free" name="free">Free</option>
</select></td>
<td></td>
</tr>
<tr>
<td align="center">4th Level: </td><td><input type="text" name="fourth" size="10" value="5"></td><td>7.5</td>
</tr>
</form>

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'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()
{
var medical=document.getElementById("medical_list")

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? I'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>

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> 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>
</select>
<select id="hotelnames" name="hotelnames" onChange="loadHotel();">
<option value="Inverary Resort, Baddeck">Inverary Resort, Baddeck</option>
</select>
</form>

can some one please advise on a cross browser solution? thanks in advance. Omar. |
