JavaScript - Need Help Passing Current Value Of Fields Into Dynamic Dropdown. Getting Undefined
So i have a form with fields (30+), and about 5 of them are fields that need to pass into my dropdown (actually a dynmaic dropdown, select SOURCE, then whatever source u select it'll show options that are mysql source=$source), so it can go into my mysql query, and filter out the best results. (i.e date_of_birth, min_credits, state, etc). Needs to be done without submitting, hence javascript. Im echo'ing my query and its saying the variables i'm trying to pass are UNDEFINED. Am I not passing the vars correctly? do i need to prep the vars to "grab" them in the current field?
this is what i have in my <head> Code: <script language="javascript" type="text/javascript">
function getXMLHTTP() { //fuction to return the xml http object
var xmlhttp=false;
try{
xmlhttp=new XMLHttpRequest();
}
catch(e) {
try{
xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e1){
xmlhttp=false;
}
}
}
return xmlhttp;
}
function getSchool(id,hs_grad_year,dob_day,dob_month,dob_year,min_credits,state) {
var strURL="findSchool.php?source="+id+"&hs_grad_year="+hs_grad_year+"&dob_day="+dob_day+"&dob_month="+dob_month+"&dob_year="+dob_year+"&min_credits="+min_credits+"&state="+state;
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('schooldiv').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
function getSub(id,cid) {
var strURL="findSub.php?source="+id+"&cid="+cid;
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('subdiv').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
</script>
The only var that is passing is SOURCE, and that's because its the name of the first dropdown I'm VERY new to javascript, do i need to set up like a GET method on my RECEIVING page? or can i just pass variables through? Do i need to get the "existing" data in the fields first? Thanks in advance, JT Similar TutorialsThe page loads and existing data is put in their correct fields. When I click 'add more' to add more fields to the form it does so and I am able to add new data. If on adding a new fields and its data I click 'add more' again it clears out the recently added data from the fields. The existing data that was present when the page first loaded is still their but all the new fields added data is cleared. how can I get it so the data stays, like in phpmyadmin when adding new fields. JS Code: function addmore(addwhat) {
// count existing boxes to find out next number to use.
// ?
if (addwhat == 'addresses') {
fieldid = 'addressesdiv';
}
if (addwhat == 'namesnumbers') {
fieldid = 'namesdiv';
}
var dv = document.getElementById(fieldid).innerHTML;
var lines = dv.match(/<br>/ig).length;
if (addwhat == 'addresses') {
document.getElementById('addressesdiv').innerHTML += '<textarea name="address' + lines + '" cols="30" rows="2"></textarea><br>';
}
if (addwhat == 'namesnumbers') {
document.getElementById('namesdiv').innerHTML += '<textarea name="name' + lines + '" cols="30" rows="2"></textarea><br>';
document.getElementById('mobilesdiv').innerHTML += '<textarea name="mobile' + lines + '" cols="30" rows="2"></textarea><br>';
}
}
PHP Code: <?

Hi, i need some help with this if is possible. I make this dropdown: Code: <dl class="dropdown"> <dt><a><span>Select a Field</span></a></dt> <dd> <ul id="menu-tags-menu" class="menu"> <li id="menu-item-159" class="menu-item current-menu-item"><a href="http://myweb.com.ar/portfolio/">All Fields</a></li> <li id="menu-item-54" class="menu-item"><a href="http://myweb.com.ar/tag/branding/">Branding</a></li> <li id="menu-item-55" class="menu-item"><a href="http://myweb.com.ar/tag/print-design/">Print Design</a></li> <li id="menu-item-57" class="menu-item"><a href="http://myweb.com.ar/tag/web-design/">Web Design</a></li> <li id="menu-item-56" class="menu-item"><a href="http://myweb.com.ar/tag/ui-design/">UI Design</a></li> <li id="menu-item-52" class="menu-item"><a href="http://myweb.com.ar/tag/motion-graphics/">Motion Graphics</a></li> <li id="menu-item-53" class="menu-item"><a href="http://myweb.com.ar/tag/illustration/">Illustration</a></li> </ul> </dd> </dl> Working with jquery and this code: Code: $(document).ready(function() {
$(".dropdown dt a").click(function() {
$(".dropdown dd ul").toggle();
});
$(".dropdown dd ul li a").click(function() {
var text = $(this).html();
$(".dropdown dt a span").html(text);
$(".dropdown dd ul").hide();
$("#result").html("Selected value is: " + getSelectedValue("sample"));
});
function getSelectedValue(id) {
return $("#" + id).find("dt a span.value").html();
}
$(document).bind('click', function(e) {
var $clicked = $(e.target);
if (! $clicked.parents().hasClass("dropdown"))
$(".dropdown dd ul").hide();
});
});
This works very well.. but i need the dt a span show me the value of the current li (<li class="current-menu-item">), so instead "Select a Field" must say "All Fields" (current value in this example), and when i go to "Motion Graphics" (for example), when page is load must say "Motion Graphics". Can i do this adding a variable to take the value of current li and droping when document.ready? Thanks Hello, I have this reservation form found on the main page of: http://www.avis.com.lb/ As you can see the current month "August" is selected as the default month and so is the year and day (the day is programmed to jump 2 days ahead for the renting of the car...) However if you look closely (check the screenshot attached) you'll see that the month "August" is repeated twice and so is the year "2009", the current month is repeated twice. What I wanna do is remove the duplication and just auto select the current month without duplicating it. I found this code: http://www.experts-exchange.com/Prog..._24229186.html But it doesn't seem to work with my form, I donno why. Here is the code of the script both javascript and a little bit of php PHP Code: $date = strtotime("+2 day"); $date2 = date('j',$date); $date4 = strtotime("+5 day"); $date3 = date('j',$date4); if($date3 == 1){ $nextmonth = strtotime("+1 day"); $monthid = date('m',$nextmonth); }else{ $nextmonth = strtotime("+0 day"); $monthid = date('m',$nextmonth); } if ($monthid==1){ $year = date("Y") + 1; }else{ $year = date("Y"); } //$pupday = date("j") - 12; //$pupday = date("d") + 2; //echo $pupday; //$returnday = date("d") +5; $month = date("F"); Code: var xMonths = new Array( '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12' );
function getListValue( option_object ){return option_object[ option_object.selectedIndex ].value;}
function setListValue( option_object, value ){ option_object.selectedIndex = value;}
function addDays(myDate,days) {
return new Date(myDate.getTime() + days*24*60*60*1000);
}
function init()
{
xToday = new Date();
yToday = addDays(new Date(),3);
xMonth = xToday.getMonth();
xDay = xToday.getDate()-1;
xYear = xToday.getYear()-2005; if (xYear < 2005) xYear=0;
yMonth = yToday.getMonth();
yDay = yToday.getDate()-1;
yYear = yToday.getYear()-2005; if (yYear < 2005) yYear=0;
xF = document.forms['quickbooking'];
setListValue( xF.ETAHour, 9 )

Help is very appreciated, thanks. i am getting a problem while passing parameter to another 'jsp' through hidden variables.I am getting null while requesting the parameter in 'mywindow.jsp' my code goes like this <form name="name" enctype="multipart/form-data"> <input type="hidden" name="flag" id="flag" value=""/> ........ </form> setting its value in javascript.. like this.. <script type="text/javascript"> function openNewWindow(){ var flag1="1"; document.getElementById("flag").value=flag1; document.tstForm.action = "Mywindow3.jsp"; document.tstForm.method = "POST"; document.tstForm.submit(); } </script> in mywindow.jsp:: <% String strFlag = request.getParameter("flag"); out.println("strFlag:"+strFlag); %> i am getting "null" as value of strFlag.I need to use enctype as "multipart/form-data" to submit form. what can be the reasons for the same code which works perfectly in notepad to not show its result in a jsp application done using eclipse??anything to do with settings?

//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);

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);

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. 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? Thanks for your help. Code: <!DOC HTML>

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;"> 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>

any help would be appreciated. thanks 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: I am developing a site that adds multiple dynamic buttons.

Thanks Paul Brown Hi, On a registration form I have 4 fields that are all dropdown select fields. NAME, CLASS-1, CLASS-2, CODE 1) I would like to activate the CLASS-1, CLASS-2, CODE fields only if the NAME IS Selected from the dropdown. 2) Also would like to make the CLASS-1, CLASS-2 as required fields if the NAME is selected from the dropdown. How can I achieve this? Can I use some kind of a server event to activate / deactivate the fields on the form? Please advice Thanks Vinny The Script works in Firefox, BUT not in Internet Explorer. What am I missing? I need Drop Down menu Boxes to appear when User clicks on a certian Menu option. The way it appears now on the website is all the boxes appear. They should stay "hidden" until a User clicks on the drop down menu selection.
