Mirror Textbox Doesn't Work On Second Try	View Content

Hi,

I'm trying to mirror two textboxes with the following:

Code:

<form>
<input type="text" id="0" name="tb1[]" onkeyup="document.getElementsByName('tb2[]')[this.id].setAttribute('value',this.value)">

<input type="text" id="0" name="tb2[]" onkeyup="document.getElementsByName('tb1[]')[this.id].setAttribute('value',this.value)">
</form>

If I start by picking the first box and typing it appears automatically in the second textbox. It works the same if if i start by picking the second box. However after entering text into one of the textboxes and having it mirrored, if I select the other textbox and make a change it isn't mirrored.

Any suggestions? Thanks!

I have a few tabs on my website. They're each set to the corresponding id in the JS file. It's supposed to add #tab-1 to the end of the URL in the users browser when it's clicked. For example, when a user is at mypage.com and they click on the tab, it ads mypage.com/#tab-1 to the end. How come it doesn't do what I want when I click it though?

Here's an example of how it's setup.

HTML:

<a href="#tab-1" id="tab1">Text</a>

JavaScript:

document.getElementById("tab1").onclick = function(){
this.href += "#tab-1";
}

Heya,

I wrote the following page in a day or two (please don't mind the layout). Everything seems to work excellent, apart from in Firefox (FF) in which it doesn't seem to work at all. None of the other browsers have any trouble with it.

I'm pretty new to Javascript (everything you see in the source code is pretty much all I know) and I have absolutely no idea why it doesn't work in Firefox.

The page in question could be found [link has been removed]. It's all there is to it.

So yeah, how to actually make this work in FF? Thanks a whole bunch in advance! Much appreciated.

Javascript Doesn't Work With Ie

Hi!

I'm new to JavaScript and I've done some small adjustments to my clients site, but it won't show properly in IE (the shadowbox js at least.). I thought js was accepted in all newer browsers. Do you have a quick fix or idea on why it doesn't work? You can view source on my site, I use mootools, and shadowbox/corners and rightclick blocker.

Is it generally a 'bad thing' to use js in webpages I want everyone to view in the same way? I tried the same effects with CSS but it's not supported in the same way corss-browser, unfortunately. The 'no selection' CSS class I have on the site is also not accepted in IE. It's very annoying!

Js Function Doesn't Work :-(

Hi!

What am doing wrong? The script works -- identifies blank fields -- but the second function (change_subject) is ignored.

This is the script:

Code:

<HEAD>
<script>
  function is_filled()  
  {
    if (form_1.realname.value=="")
      {
        alert("Please enter your name")
        form_1.realname.focus()
        return false
      }
    if (form_1.subject.value=="")
      {
        alert("Please enter a subject")
        form_1.message.focus()
        return false
      }
else
return true
  };
  function change_subject
  {
  form_1.subject.value="form_1.realname.value + '_' + form_1.subject.value"
  };
</script>
</HEAD>

This is the FORM (used for MSA FormMail):

Code:

	  <form  name="form_1"; onSubmit="return is_filled()"; on Submit="change_subject()"; method="post"; action="http://gb2gf.org/cgi-sys/FormMail.cgi">
	  <input type="hidden" name="recipient"    value="drt@gb2gf.org">
	  <input type="hidden" name="required"     value="greeting,realname,city_state,email_1,email_2,message">
	  <input type="hidden" name="sort"         value="order:greeting,realname,city_state,email_1,email_2,message">
	  <input type="hidden" name="redirect"     value="http://www.gb2gf.org/thanks.htm">

<!-- Input fields here -->

           </form>

Thanks!

Replace Doesn't Work ??

I've got a form textarea on my site, which after being submitted is stripped by my php file.

Then my javascript kicks in and does some analysis of the entered text. However everytime the user entered a hard return within the textarea my javascript gives me an error 'tekenreeks niet afgesloten' which means something like 'string is not closed'.

Therefore I decided to replace all occurences of chr(10) and chr(13) with
ok2 (just some random characters), I did this with php which worked fine, and I didn't get the javascript error.

However I need to reshow the entered text (original) to the user, so I need to restore the old values. I tried Code:

result.waarde.replace('ok2', 'chr(13)');

but it doesn't work, as it still displays ok2.

I'm no expert in javascript, but how can I replace those characters by the hard returns?

Oh yeah I'll show some more coding, perhaps the error can be found the
Code:

result.waarde.replace('mdw', 'chr(13)');container.innerHTML = result.waarde;

and in my html:
Code:

<div id='waarde' style="width:500px;"></div>

<h1>scrollHeight Property Sample</h1>
<p>This sample demonstrates the use of the <b>scrollHeight</b> property to retrieve
the height of the viewable content.</p>
<div id="oID_1" style="overflow: scroll; height: 200px; width: 150px; text-align: left">
The <b>scrollHeight</b> property is read-only, allowing you to obtain the
actual height of the scrollable content. Even though the height of this
<b>div</b> is 200 pixels, the height inside the scrolling text box might
be less, since the wrapped text may not use the entire area within the object.
The <b>scrollHeight</b> dimension may be useful for a variety of reasons;
for example, the height of the <b>div</b> could be set to the <b>scrollHeight</b>
to conserve horizontal space while respecting the set width as a maximum.
</div>

<p><button id="btnCheck" onclick="fnCheckScroll()">Check scrollHeight
</button></p>
<p><button id="btnSetIt" onclick="return(fnSetHeight());">Set DIV height to scrollHeight
</button></p>

Hi, doing form validation at college just now. The lecturer gave all of us this following example. But it doesn't seem to work in firefox. I have tried my own scripts and they seem to work so have no idea whats happening!

Code:

<script type="text/javascript">

function ValidateForm()

var msg='';
if(document.getElementById('CC').value=='')

  }
else
// Now test if CC is purely 2 capital letters...

  {
   var CC=RTrim(document.getElementById('CC').value);
// alert(CC);
   if (CC.length==2)
   {
      if (isCHAR(CC)==false) 
      {
       msg+=' - CC not solely 2 capital letters \n\n';
      }
   }
   else
       msg+=' - CC not 2 letters in length \n\n';
  }

if(document.getElementById('NNNNNN').value=='')
 {
	msg+='- Please enter NNNNNN \n\n';
  }
else

// Now test if NNNNNN is purely 6 digits...

   var NIdigits=RTrim(document.getElementById('NNNNNN').value);

   msg+=' - NNNNNN not 6 digits in length\n\n';
   }
   
// Lastly check if the last field contains only 1 char
   
if(document.getElementById('C').value=='')
 {
	msg+='- Please enter C \n\n';

 }
else
// Now test if C is a single letter...

  {
   var C=RTrim(document.getElementById('C').value);

  if (C.length==1)
   { 
   if (isCHAR(C)==false)
   {
       msg+=' - C not a capital letter \n\n';
   }
   }
   else
   msg+=' C not 1 character in length';

My switch function just goes to the default. I've double double checked the file paths of the image on the page and it's right. So I'm not sure what's going on. here's what I got:

Code:

function change2(picName,imgName)


{
switch (document[picName].src)
  {
  case document[picName].src= "images/leaf_shapes/leaf_auriculate.gif":
    document[picName].src = "images/leaf_shapes/crenate/leaf_elliptic_crenate.gif";
    break;
  case document[picName].src= "images/leaf_shapes/leaf_cordate.gif":
    document[picName].src= "images/leaf_shapes/serrate/leaf_elliptic_serrate.gif";  
  break;
  default:
    document[picName].src= "images/leaf_shapes/transparent1.gif";

Need A Quick Refresher- Why Doesn't This Work?

Similar Tutorials

I'm having one of those moments right now. Can someone explain why the following alerts "undefined" instead of "George"?

Code:

function test(){
this.worker='George'
}

test.sayname=function(){
alert(this.worker)
}


test.sayname() //alerts "undefined"

I know I can get it to alert "George" by instantiating test(), but I thought the above should work even without doing that.
