JavaScript - Toggle Form Test Failed - Revised

I have a function to accept number and certain text only when "Enter" key is pressed.
Code:

function handleEnter(field, event){
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
var tmp_val = "";
       if (keyCode == 13) {
		if(field.name=="number" && field.value.replace(/ /g,"").length>1){	
			field.value = field.value.replace(/ /g,"");
			field.value = field.value.toUpperCase();
			tmp_val = field.value;
			if (isNaN(tmp_val) && tmp_val!="ABC") {
				field.value = "";
				field.focus();
				return false;
			}
                       else {
                          some codings here
                       }
               }
       }
}

However, when I added a second condition, the code stops working
Code:

if (isNaN(tmp_val) && (tmp_val!="ABC" ||tmp_val!="DEF") )

Anyone pls help~ Tks~

I have:

Windows server 2008 enterprise edition
Apache 2.2.15 for windows
Netbeans 6.7.1
Glassfish 2.1
Drupal 6.17 (that by default
PostgreSQL 8.4 administrated through pgAdmin 1.10.0 (to store Netbeans elaborated data)
Firefox and Chrome give me the same problem, tools used are even Httpfox and Fiddler2

Problem:

I have a page where the user has to insert his own data, there are 2 types of data, Atributos and Datos. Atributos are on a atributos_user table in PostgreSQL and has 49 columns, Datos on datos_user, that has 119 columns. So when I clic on save, the js file on the page does:

Code:

function guardaTodo(){

var retvalue;

retvalue = guardarMisDatos();
if(retvalue == false) { return retvalue; }
retvalue = guardarAtributos();

}

The function guardarAtributos works fine, so I guess that this one above is written correctly. The function guardarMisDatos is written the same way, and pretends to collect all the data through Netbeans. so whenever I click on the save button, i get in the web console this:



The function guardarMisDatos does like this:

Code:

var param ="&usuario="+usuario+"&nivel="+nivel+gano+porc_gano+gasto+porc_gasto+tengo+porc_tengo+debo+     porc_debo+plazo_debo;
 var s = document.createElement("script");
 s.type = "text/javascript"; s.async = true;
 s.src = server_direction +"setMisDatos?callback=respuestaGuardarMisDatos&param="+encodeURIComponent(param);
 var h = document.getElementsByTagName("script")[0];
 h.parentNode.insertBefore(s, h); //or h.appendChild(s);

where every variable of the "param" is taken like this:

Code:

var plazo_debo_casa1 = (getValor("plazo_debo_casa1"));
var plazo_debo_casa2 = (getValor("plazo_debo_casa2"));
var plazo_debo_casa3 = (getValor("plazo_debo_casa3"));
var plazo_debo_prestamo1 = (getValor("plazo_debo_prestamo1"));
var plazo_debo_prestamo2 = (getValor("plazo_debo_prestamo2"));
var plazo_debo_prestamo3 = (getValor("plazo_debo_prestamo3"));
var plazo_debo ="&plazo_debo_casa1="+plazo_debo_casa1+"&plazo_debo_casa2="+plazo_debo_casa2+"&plazo_debo_casa3="+plazo_debo_casa3+"&plazo_debo_prestamo1="+plazo_debo_prestamo1+"&plazo_debo_prestamo2="+plazo_debo_prestamo2+"&plazo_debo_prestamo3="+plazo_debo_prestamo3;

so anytime I call the function, i mean, i click on save, the browser fires:

Code:

http://www.mirodinero.com:8080/mirodinero-war/setMisDatos?callback=respuestaGuardarMisDatos&param=%26usuario%3DIsa%20Mirodinero%26nivel%3D109%26gano_sal_neto%3D211113.45%26gano_sal_prof%3D234480%26gano_monet%3D0%26gano_renta_fija%3D0%26gano_renta_vble%3D0%26gano_inmuebles%3D6750%26gano_otros%3D23730%26gano_otros_ing%3D411125%26porc_gano_monet%3D0%26porc_gano_rentaf%3D0%26porc_gano_rentav%3D0%26porc_gano_inm%3D2%26porc_gano_otros%3D2%26porc_gano_otros_ing%3D1%26gasto_casa1%3D1306.46%26gasto_casa2%3D2402.38%26gasto_casa3%3D3999.57%26gasto_prestamo1%3D93475.58%26gasto_prestamo2%3D7325.88%26gasto_prestamo3%3D34090.9%26gasto_tarjetas%3D29443.2%26gasto_ibi%3D5670%26gasto_imp_otros%3D6780%26gasto_seg_inm%3D1320%26gasto_seg_pens%3D3451.22%26gasto_seg_vida%3D330%26gasto_seg_plan%3D34230%26gasto_seg_medico%3D1220%26gasto_seg_coche%3D20%26gasto_luz%3D620%26gasto_agua%3D4550%26gasto_gas%3D320%26gasto_telef_f%3D320%26gasto_telef_m%3D350%26gasto_internet%3D20%26gasto_tv%3D3450%26gasto_hogar%3D20%26gasto_comida%3D20%26gasto_cenas_copas%3D20%26gasto_viajes%3D20%26gasto_vacaciones%3D220%26gasto_mobiliario%3D220%26gasto_ropa%3D2320%26gasto_transp%3D20%26gasto_otros%3D620%26gasto_colegios%3D240%26gasto_univ%3D340%26gasto_master%3D2230%26gasto_otros_gastos%3D73433%26porc_gasto_tarjetas%3D0%26porc_gasto_ibi%3D0%26porc_gasto_trib%3D0%26porc_gasto_seg_inm%3D0%26porc_gasto_seg_pens%3D0%26porc_gasto_seg_vida%3D2%26porc_gasto_seg_plan%3D2%26porc_gasto_seg_med%3D0%26porc_gasto_seg_coche%3D0%26porc_gasto_sum_luz%3D2%26porc_gasto_sum_agua%3D2%26porc_gasto_sum_gas%3D0%26porc_gasto_sum_teleff%3D0%26porc_gasto_sum_telefm%3D0%26porc_gasto_sum_int%3D0%26porc_gasto_sum_tv%3D0%26porc_gasto_nivel_hogar%3D0%26porc_gasto_nivel_comida%3D0%26porc_gasto_nivel_cenas%3D0%26porc_gasto_nivel_viajes%3D0%26porc_gasto_nivel_vacac%3D0%26porc_gasto_nivel_mob%3D0%26porc_gasto_nivel_ropa%3D0%26porc_gasto_nivel_transp%3D0%26porc_gasto_nivel_otros%3D0%26porc_gasto_colegios%3D2%26porc_gasto_univ%3D0%26porc_gasto_master%3D0%26porc_gasto_otros_gastos%3D23%26tengo_casa1%3D1231.11%26tengo_casa2%3D10000%26tengo_casa3%3D22240%26tengo_otras%3D23560%26tengo_monetario%3D1212.34%26tengo_planpensiones%3D23230%26tengo_otros%3D23330%26porc_tengo_casa1%3D1%26porc_tengo_casa2%3D0%26porc_tengo_casa3%3D2%26porc_tengo_otras%3D0%26porc_tengo_monet%3D0%26porc_tengo_plan%3D0%26porc_tengo_otros%3D0%26debo_casa1%3D4340%26debo_casa2%3D23450%26debo_casa3%3D23430%26debo_prestamo1%3D23330%26debo_prestamo2%3D6871.11%26debo_prestamo3%3D11340%26debo_tarjetas%3D61340%26porc_debo_casa1%3D30%26porc_debo_casa2%3D10%26porc_debo_casa3%3D12%26porc_debo_prestamo1%3D1%26porc_debo_prestamo2%3D12%26porc_debo_prestamo3%3D1%26porc_debo_tarjetas%3D4%26plazo_debo_casa1%3D230%26plazo_debo_casa2%3D450%26plazo_debo_casa3%3D122%26plazo_debo_prestamo1%3D3%26plazo_debo_prestamo2%3D12%26plazo_debo_prestamo3%3D4

and doesn't work on the first click, or after 30 seconds idle, like browsing another tab, etc.

Tried Solutions:

Tried changing h.appendChild(s) to parentNode.insertBefore(s, h) -> works better but not enough
Change the order of guardaTodo exchanging the 2 functions -> guardarMisDatos never works
Included httpd-default.conf to the httpd.conf file, setting this parameters:

Timeout: The number of seconds before receives and sends time out. Timeout 30000

KeepAlive: Whether or not to allow persistent connections (more than one request per connection). Set to "Off" to deactivate. KeepAlive On

MaxKeepAliveRequests: The maximum number of requests to allow during a persistent connection. Set to 0 to allow an unlimited amount. We recommend you leave this number high, for maximum performance. MaxKeepAliveRequests 0

KeepAliveTimeout: Number of seconds to wait for the next request from the same client on the same connection. KeepAliveTimeout 500

Divide the guardarMisDatos function into more pieces, like saving only part of the Datos -> it works fine on that columns that i'm saving, but deletes all remaining columns

What I'm searching for:

I have been searching what kind of setting I should change in Apache httpd.conf to enable a connection that doesn't timeout and opens on the right time. My Apache httpd.conf is of the kind that includes other httpd-*.conf files.

Findings:

From httpfox i get NS_ERROR_NET_RESET, that occurs on the first click to the "save" button, or after a while that i don't view that page. I counted how much time shall I stay idle to "lose" the connection (and get the same error), it's more or less 30 seconds. So I even checked with fiddler2, and get this kind of message:

"ReadResponse() failed: The server did not return a response for this request."

Observation (Similar case):

I've found this question to have a problem similar to mine, but I already talked with my hosting service and they told me that there is no firewall preventing connections.



Solution:

I don't have a solution, it's been weeks now, and probably nobody helped me because the stuation was not well explained, that's why now i wrote it down with more details as possible. I hope that now this is well explained and to get some help.

Hello. Can anyone please tell me what information in the second java script code needs to be changed to make a toggle expand in place. The toggles currently expand properly, but the second toggle, as well as the others, jump back up to the first toggle when expanded.


The first toggle:

<script type="text/javascript">// <![CDATA[
function toggleView(layer_on, layer_off) { document.getElementById(layer_on).style.display = 'block'; document.getElementById(layer_off).style.display = 'none'; return; }
// ]]></script>



The second toggle:

<script type="text/javascript">// <![CDATA[
function toggleView(layer_on, layer_off) { document.getElementById(layer_on).style.display = 'block'; document.getElementById(layer_off).style.display = 'none'; return; }
// ]]></script>

Here is the referenced page:

http://sprintexperts.info/phones/#

Thanks in advance!

I'm not sure if this is a JS or CSS problem, but I figure I would start here.

What is wrong with the "onload" function that makes it so that I can not initialize the class name?

I get no errors and the toggleClass(IDS) function appears to work fine with similar logic tests.

What I expect to happen is that the <blockquote id=...> class names be initialized to hide
if and only if JS is available for the toggleClass function to work.

Here is what I am doing...
Code:

<!DOC HTML>
<html>
<head>
<title> Toggle Class </title>
<script type="text/javascript">
//<![CDATA[
function toggleClass(IDS) {
  var sel = document.getElementById(IDS);  //  alert(IDS+' : '+sel.className);
  if (sel.className != 'hide') { sel.className = 'hide'; }
                          else { sel.className = 'show'; }
}
window.onload = function() {
  var sel = document.getElementsByTagName('*');
  for (var i=0; i<sel[i].length; ++i) {
    if (sel[i].className == 'show') { sel[i].className = 'hide'; alert(sel[i].id); }
  }
}
//]]>
</script>
<style type="text/css">
 .show { display: block; }
 .hide { display: none; }
 li { list-style-type: none; }
 #Schedule { margin:0px; padding:5px; }
 #Projects { margin:0px; padding:5px; }
</style>

</head>
<body>
<a href="#" onclick="toggleClass('Schedule');return false"> Schedule </a>
<blockquote id="Schedule" class='show'>
 <li>Monday:</li>
 <li>Tuesday:</li>
 <li>Wednesday:</li>
 <li>Thursday:</li>
 <li>Friday:</li>
</blockquote>
<br>
<a href="#" onclick="toggleClass('Projects');return false"> Projects </a>
<blockquote id="Projects" class='show'>
 <li>Current</li>
 <li>Past</li>
 <li>Future</li>
 <li>On-going</li>
</blockquote>

</body>

I had some help last week with a brands a to z list which shows a div containing list of brands starting with the relevant letter onclick.

It works pretty well with one flaw. The brand links within the div seem to activate the toggle function. My wish is that the layer is shown when a letter is clicked but then hides on div onMouseOut so that a different letter can be selected.

Here is by code;

Javascript;
Code:

function toggle_visibility(o,id) {
 var obj = document.getElementById(id);
 obj.style.display=(obj.style.display == 'block')?'none':'block';
 if (obj.style.display!='none') {
 obj.style.left=zxcPos(o)[0]+20+'px';
 obj.style.top=zxcPos(o)[1]+20+'px';}
}

function zxcPos(obj){
 var rtn=[0,0];
 while(obj){
  rtn[0]+=obj.offsetLeft;
  rtn[1]+=obj.offsetTop;
  obj=obj.offsetParent;
 }
 return rtn;
}

Here is a sample of my a to z table;
Code:

<table width="100%" border="0" cellspacing="2" cellpadding="2">
<tr>
<td align="center" class="LN-Brands-Alphabox"><a href="#" onclick="toggle_visibility(this,'uniquename20');">U</a></td>

<td align="center" class="LN-Brands-Alphabox"><a href="#" onclick="toggle_visibility(this,'uniquename21');">V</a></td>

<td align="center" class="LN-Brands-Alphabox"><a href="#" onclick="toggle_visibility(this,'uniquename22');">W</a></td>

<td align="center" class="LN-Brands-Alphabox"><a href="#" onclick="toggle_visibility(this,'uniquename23');">X</a></td>
</tr>
<tr>
<td align="center" class="LN-Brands-Alphabox"><a href="#" onclick="toggle_visibility(this,'uniquename24');">Y</a></td>

<td align="center" class="LN-Brands-Alphabox"><a href="#" onclick="toggle_visibility(this,'uniquename25');">Z</a></td>
        
</tr></table>

And here is an example of the Brand name div ;
Code:

<div id="uniquename21" onMouseOut="toggle_visibility('null','uniquename21');" style="display:none; position:absolute; border-style: solid;  background-color: white;  padding: 5px;">
<a href="Manufacturer-view.asp?ManID=43">VPX</a><br>
<a href="Manufacturer-view.asp?ManID=44">Vyomax</a>
</div>

(Brand menu on the left nav)

Thank you for any help you can give

I am trying to toggle a button (button-top) to move 860px to the right when clicked, while a div panel (textbox1) with text slides down next to it. The panel toggles fine when the buttons (wrap or button-top) are clicked, but the button moves to the right, and then does not move back to its original position when the buttons are clicked the second time. I have tried so many different methods of coding this, but i have problems where the button keeps moving further to the right every time it is clicked. or when it does move back, it does it automatically (not on click) and suddenly disappears.

Here is the code that I have ended up with so far.

Code:

$(function() {
	$("#textbox1").hide();
	$("#wrap").click(function() {
				$("#button-top").animate({right: "860px"}, 2000);
				$('#textbox1').animate({height: "toggle"}, 2000);
	});
});

Hi all, looking for some help. I found this script that does almost everything i need.
I have a form that has a small section of two radio buttons
when you click on the first one i need a series of text boxes to open wrapped in a div box and that happens great, but when the other one is clicked i need them to go away, the whole div box.
also the text boxes also have some hidden fields attached to them will not not pass to the shopping cart if the text boxes are disabled.

here is what i have so far.
placed in head
Code:

<SCRIPT LANGUAGE="JavaScript">
function toggle(chkbox, group) {
    var visSetting = (chkbox.checked) ? "visible" : "hidden"
    document.getElementById(group).style.visibility = visSetting
}</script>

Code:

<span class="style30" style="text-align:center">Send directly to recipant:</span><input name="product3[]" type="radio" onclick="toggle(this, 'shipGroup');" value="{br}{b}SEND CERT DIRECTLY TO RECIPANT---{/b}"/>

please anyone with help will be great

I've gone far enough with my website and thanks to you guys i completed a lot of issues i had.

I just included a browser detect snippet which is supposed to show the pages correctly on IE, Firefox, Safari, Opera and Chrome.

I understand that watching a greek site won't make much sense for you, but i'm hoping you will at least understand how the thing goes. The first yellow box on your left is the menu. Clicking there will take you to the menu's categories. You will find a few categories in english there, at least

Now, in each category, clicking the button below the product should put it in the cart, part of it appears on every page in a floating layer to the top-right. There is also a link in there to "checkout" (ΟΛΟΚΛΗΡΩΣΗ ΠΑΡΑΓΓΕΛΙΑΣ). This is where the problem comes: In every browser except Chrome, the list of items of the cart will appear. I don't know why but in Chrome, not only i see nothing in there, but it also deletes everything in the cart!

If any of you, specially the ones who have many browsers installed, could spend a little time testing my site, i would really appreciate it. Old Pedant and Phillip should be more aware since you guys have already helped me out and you kinda know the functionality of the site.

The address is: lukulos.gr (works directly now, no need to type specific files)

hello guys, I'm new here ..

I am developing a fw js, now I have to test the selector $..

operation is similar to jquery

$('#Id')

$('table td .class)

If there are several factors you should:

$('table td .class).each(function ()
{
this ..
});

or

$('table td .class).item(number) ...

can be used to test the methods set / get the attributes or setCSS or getCSS for styles ..

Thanks to all

I am creating a website as part of a university project. as part of this i am trying to make a menu in the top right. after looking around i have found javascript top be the best way to do this.
how would i go about making it so that when i click on one div (called map) a separate div (called mapMenu) visibility is toggled.

thanks

Delete.

I created an FAQ toggle for my site.

I have the toggle working great. The problem is everytime I click one of the toggle links I am brought to the top of the page.


Here it is.

Any help is appreciated.

Hey, while your there if you want to like my site on facebook, I won't complain.

Following are my script to toggle b/w two different links,

<html lang="en-US">
<head>
<title>toggle b/w 2 different links</title>
<script type="text/javascript"><!--
display=1;
function displayvalue()
{
document.getElementById("sv1").style.display = "block";
document.getElementById("dw1").style.display = "none";
}
function ShowHide()
{
if (display==1) {
document.getElementById("sv1").style.display = "none";
document.getElementById("dw1").style.display = "block";
//document.getElementById('javaFun') calling java func from javascript
display=2;
}
else {
document.getElementById("sv1").style.display = "block";
document.getElementById("dw1").style.display = "none";
//document.getElementById('javaFun1') calling java func from javascript
display=1;
}
}
function Func1Delay()
{
document.getElementById("sv1").style.display = "none";
document.getElementById("loadimage").innerHTML="<input type='image' src='Loading.gif'>";
setTimeout("LoadImage()", 300);
}


function LoadImage()
{
document.getElementById("loadimage").innerHTML="";
ShowHide();
}


--></script>
</head>
<body background="GsNJNwuI-UM.gif"onload="displayvalue()">




<div id="sv1" >
<a onclick ="Func1Delay()" href="javascript:;">click me</a>
</div>
<div id="loadimage"></div>
<div id="dw1" >
<a onclick ="ShowHide()" href="javascript:;">Download me</a>
</div>
</body>
</html>

whenever we call a java method , (consider this line:- document.getElementById('javaFun');)after the completion of java call the page is reloading, how control this reloading after the server completing the request....?

I'm sure this is a simple thing to do, but I know next to zero javascript and can't find an example online.

What I want to do is to toggle a number on a webpage when a user clicks a link.

So ideally there would be a "click to toggle" link, and then a number (lets say 400), when the user clicks that toggle link the number would change to 800 (or whatever my variable is set to), when they click it again it would go back to that original number (in this case 400).


Would someone be kind enough to help me with this?


Thanks
