How to do that ? Getting nowhere with this. Code: function doit(tmpObj)

I have an input element of type=text. It has a fixed width, but I want to expand that width as the user is typing if the text doesn't fit inside. I did something similar to this with <textarea> and the vertical height. PHP Code: // javascript in mootools textarea.addEvent('keyup', function(){ textarea.setStyle('height', this.getScrollSize().y ); }); Does anyone know of a way to do this with <input type='text'>? Newbie here. I could not find the syntax how to set initial value he Code: var indat = window.clipboardData.getData ("Text");
.
.
.
.
.
<input type="text" name="q" value="xxxxxx" size="40" />
I would like the value to be the indat var value I saw lot of samples with value="xxxxx" (hard coded value) but could not find sample for var value thanks for help !! Howdy I have a <input type="File"> in my html, I need it because the user can select a jpg image and when they click submit it will post that image to a webservice. My question... Is their a way to load the file they selected so that I can draw it on a canvas? Sounds simple but I cannot figure it out! Thanks in advance Eckythump I have a page with a customizable background. The user can choose a picture to set as the background by finding the picture file they want after clicking the upload input. The path of the file they select is saved into a cookie, and the page then switches backgrounds. This all works perfectly, but the value that the upload input returns is only the file name, not the full path. For example, let's say I wanted to choose a picture named "bg.jpg" in the "Windows" folder of the C drive. The full path would be "C:/Windows/bg.jpg". However, the value that the input returns is just "bg.jpg". How would I have the input return the entire path of the file using JavaScript? This has been bothering me for a while...any help would be much appreciated. Hello all, I have in my application input type file for uploading files. How can i do javascript validation to check if filename has special characters in it?? Thanks Below is a script I found at http://bytes.com/topic/javascript/an...cookie-problem The idea is a like button, like on fb, in a form which updates a db field I can use to display the number of likes, and my goal is to disable the like button for the rest of the session, or a day, or whatever. This script disables it onclick, the problem is I can't figure out how to get it to submit the form as well. I have found it does submit if the input type is 'submit', but then it doesn't call the disable function. I tried writing another function to submit the form but no go. Code: <html>
<head>
<title>Vote Button</title>
<script type="text/javascript">
function checkForVote()
{
// If there is a cookie...
if(document.cookie != "")
{
if(getCookie("voted") == 1)
{
// Disable the button again if user already voted.
disableButton();
}
}
}
function disableButton()
{
var submitvote = document.getElementById("submitvote");
submitvote.disabled = true;
submitvote.value = "You Already Voted.";
}
function setCookie(name, value, days)
{
if(days)
{
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires = " + date.toGMTString();
}
else
{
var expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
// Disable the button as soon as the user clicks it.
disableButton();
}
function getCookie(name)
{
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0; i < ca.length; i++)
{
var c = ca[i];
while (c.charAt(0)==' ')
{
c = c.substring(1,c.length);
}
if (c.indexOf(nameEQ) == 0)
{
return c.substring(nameEQ.length,c.length);
}
}
return null;
}

In fact: does input type=image belong to the form's elements collection, in ECMAScript ? It looks like not. When traversing the form's elements collection with classical javascript (document.forms[formname].elements), an input type="image" is not included. Is this an inheritance from old browsers interpretors? Does anyone know the reason for this omission? Hello, Working With a touch screen, have created HTML page that has a custom keyboard for password input, no mouse or keyboard connected. Is there a way to enter keystrokes from the HTML into a (my form) text area (password) using Java. From the example below I am trying to put (1) into myform. <td><a class="Keys" type="password" target="myform">1</a></td> <!-- This Did not Work--> Thank You for any Info. hi guyz i do have a problem in passing javascript variable to <input type=hidden value=""> here's my code: <?php while ($row = mysql_fetch_array($result)) { ?> <script type="text/javascript"> function viewcodec(){ var randomValueCodec = randomString(5, 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'); document.getElementById('commentMarkCodeCompCodec-'+<?php echo $row['p_id'];?>).innerHTML = randomValueCodec; document.getElementById('commentMarkCodeComp-'+<?php echo $row['p_id'];?>).innerHTML = randomValueCodec; } </script> <form action="" method="post" name="postsForms"> <div class="commentBox" align="right" id="commentBox-<?php echo $row['p_id'];?>" <?php echo (($comment_num_row) ?

Once a selection is made, the value is appended to an input box. The idea is that the appended values form a telephone number, or at least part of one, that will then be used to search trough a database to look for a matching number. The code below is what I have done so far: Code: <script type="text/javascript">
function displayIndicatif(){
var sel = document.getElementById("indicatif");
var text = sel.options[sel.selectedIndex].value;
var out = document.getElementById("blabla");
out.value += text+"\n";
}
function displayBloc(){
var sel1 = document.getElementById("bloc");
var text1 = sel1.options[sel1.selectedIndex].value;
var out1 = document.getElementById("blabla");
out1.value += text1+"\n";
}
</script>
[...]
<input type="text" id="blabla"/>
[..]
<select id="indicatif" onChange="displayIndicatif();">
<option value="021">021</option>
<option value="022">022</option>
<option value="031">031</option>
</select>
<select id="bloc" onChange="displayBloc();">
<option value="555" class="021">555</option>
<option value="666" class="021">666</option>
<option value="777" class="021">777</option>
</select>
Basically what happens now is this: combobox indicatif: 021 | 022 | 031 combobox bloc: 555 | 666 | 777 If I select "021" from indicatif, the script will append 021 to the input "blabla". The problem is, if I now select "022", the input will show "021022" instead of replacing the 021 with 022. What I would like is that, for each combobox, the script replaces the selected value with the new one instead of simply appending it, like instead of say 021022555666 it would show 021555 or 022666 or 021666 depending on what is selected...you get the idea? Is this doable? Needless to say I'm a total noob at javascript...I adapted the code I got now from some other guy who was trying to achieve almost the same thing and adapted it to my needs, or least, tried to, but now I'm stuck. Any help is appreciated! Thanks this is the code for input prompt, only works in IE: any ideas why? $('input[type=text][title],input[type=password][title],textarea[title]').each(function(i){ $(this).addClass('input-prompt-' + i); var promptSpan = $('<span class="input-prompt"/>'); $(promptSpan).attr('id', 'input-prompt-' + i); $(promptSpan).append($(this).attr('title')); $(promptSpan).click(function(){ $(this).hide(); $('.' + $(this).attr('id')).focus(); }); if($(this).val() != ''){ $(promptSpan).hide(); } $(this).before(promptSpan); $(this).focus(function(){ $('#input-prompt-' + i).hide(); }); $(this).blur(function(){ if($(this).val() == ''){ $('#input-prompt-' + i).show(); } }); }); Hate to ask this as I know it's an easy one but surprisingly Google turns up no clear/simple answers! I'm modifying some old code and am not JS programmer (I'm a PHP programmer) and this is driving me nuts. The existing code makes sure that when the form is submitted that there isn't a missing value. There's also some hidden input values. The JS starts out function checkform(orderform) and the form tag includes onsubmit="return checkform(this);"> I can add an alert to the form to see varius input values, such as a hidden value for the input name 'description' I can use: alert (orderform.description.value) Eazy peazy. However the form has two different input type=image buttons now and I need to do some branching in the JS depending on which image button they press. I recall IE had an issue where it only sends the x and y coordinates So I figure an easy to determine which image button was pressed is just check to see if the x or y value for each button is non-zero. But I can't for the life of me figure out how to access the value. Example: alert (orderform.button1.x.value) doesn't work. Can someone refresh my memory or suggest an entirely different method for detecting which image button was used to submit a form? THanks in advance! I've not really an idea how to do this. I know how to do it in PHP, but I need it dynamic <input type="checkbox" name="facebook" value="1" /> if($_POST['facebook'] == 1) echo "<input type='text' name='facebook_url' />"; Could someone tell me how I should do this. Thanks. Hi all, I use a javascript to generate a checkbox list. It works well but all the <input type="checkbox"> generated have the same id. I would like to find a way to auto-implement the id (with a unique id). So if my javascript generates 10 checkboxes, I will get id from 1 to 10 or something similar. Code: // here I build the filter checkboxes based on all the class names
$.each(arrayUniqueClasses, function() {
$('<li><input class="styled" type="checkbox" checked="checked" name="1" value="'+this+'" id="1" />
<label class="check" for="1"></label>
<label class="info" for="filterID'+this+'">'+this+'<\/label><\/li>').appendTo('ul.filters');
});
so I tried something but it doesn't work at all (I'm a beginner as you can guess) : Code: var getUniqueId =
(function ()
{
var id=0;
return function()
{
if (arguments[0]==0) id=0;
return id++;
}
}
)();
Thanks for helping here the full script if needed : Code: function unique(a) {
tmp = new Array(0);
for(i=0;i<a.length;i++){
if(!contains(tmp, a[i])){
tmp.length+=1;
tmp[tmp.length-1]=a[i];
}
}
return tmp;
}
function contains(a, e) {
for(j=0;j<a.length;j++)if(a[j]==e)return true;
return false;
}

I am wanting to enable a file to be uploaded and attached to an email form. I however wish to only limit this to picture files with a size no larger than 1MB. Is there a way to do this with javaScript. My Html code: Code: <!-- Add a picture file --> <tr><td align="left">Upload your favourite Yorkie photo for the Picture of the Month.<br /> <input type="file" name="upload" accept="image/gif" size="30" style="margin-left: 15px; margin-top:5px; color: #0000; background-color: #00FF77;" /></td></tr> Just need to know if this can be validated with javascript to ensure the conditions are as per above. |
