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 !! Similar TutorialsI need to change input type="text" to input type="password" via JavaScript Code: <form id="login" action="#" method="post"> <input id="username-field" type="text" name="username" title="Username" onmousedown="javascript:this.value=''; javascript:this.focus();" value="Username" tabindex="1" /> <input id="password-field" type="text" name="password" title="Password" onmousedown="javascript:this.value=''; javascript:this.type='password'; javascript:this.focus();" value="Password" tabindex="2" /> <input type="submit" name="submit" value="sign in" tabindex="3" /> </form> This works in Firefox and Safari but not IE So then I tried this code Code: <script type="text/javascript">
function passit(ip){
var np=ip.cloneNode(true);
np.type='password';
if(np.value!=ip.value)
np.value=ip.value;
ip.parentNode.replaceChild(np,ip);
}

<input type="submit" name="submit" value="sign in" tabindex="3" />
</form>
This does what I need but turns the username type to password field not the password box Please can somone help! 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'>? Hi guys, Let me explain simply what I do and what I'm trying to achieve: I got a couple of comboboxes were the user selects a series of numbers. 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 print "<Font face=\"calibri, Arial\"><table id=\"rnatable\" border=2px width=100%>"; print "<th></th>"; print "<th>a</th>"; print "<th>b</th>"; print "<th>c</th>"; print "<th>d</th>"; print "<th>e</th>"; print "<th>f</th>"; print "<th>g</th>"; while($array = mysql_fetch_array($sql_query)) { $id=$array['a']; print "<tr id=\"newtr\">"; print "<td><input id=\"check\" type=\"checkbox\" name=\"keyword[]\" value=\"$id\" ></td>"; print "<td>".$array['a']."</td>"; print "<td>".$array['b']."</td>"; print "<td>".$array['c']."</td>"; print "<td>".$array['d']."</td>"; print "<td>".$array['e']."</td>"; print "<td>".$array['f']."</td>"; print "<td> <a href=\"http://localhost/rnasearch/retrieve.php?a=$id\">bla</a> </td></tr></font>"; } print "</table>"; } this is part of a php searchengine script that i wrote to retrieve data from a database and as you can see the last column that is g contains a link which when clicked takes the user to the second php script which retrieves additional information of that entry, but this is done for only single entries so as you can see i introduced checkboxes so that the user can check any number of checkboxes and retrieve information as per their wish now to do this i created a <input type=text where i want the value of these checkboxes i.e. $id to be posted in a delimited format so that the user can then click the corresponding button and retrieve the information this is the code <div id="floatMenu"> <ul class="menu1"> <center><li><form name="senddata" method="POST" action="http://localhost/retrieve.php" style="display:inline;"><input id="fasta" type="text" class="multitext"><input name="Fasta" type="Submit" value="Retrieve Fasta"></form> this is a css floating menu....so far so good....everything went fine.... after this i had to write a javascript to do this and i've been stuck there searching forums for the last 4 days! this is the javascript i found from somewhere which came close to doing wht i wanted it to do window.onload = function () { var cb = document.getElementById('check'); var fasta = document.getElementById('fasta'); cb.onclick = function () {fasta.value = cb.value + ","; };}; this script only sends the value of the first checkbox in the table, the others are not found by it, mind you its not the first checkbox selected its the first checkbox that is present in the table how can i resolve this problem so that even if i have n number of checkboxes in my table, if the user chooses to do so they can retrieve n number of information....please help i've almost lost hope in this! This was climbing up the tree strructure, where on top and only on very top is one input of type text Now I inserted (inside tree) some inputs of type hidden , which needs to be ignored while below while operates. How to do that ? Getting nowhere with this. Code: function doit(tmpObj)
{
while (!tmpObj.getElementsByTagName('input')[0])
{
tmpObj.style.visibility = 'hidden';
tmpObj = tmpObj.parentNode;

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 <script type="text/javascript"> function showhide(divid) { thediv = document.getElementById(divid); if(thediv.style.display == 'none' || thediv.checked=='true' ){ thediv.style.display='block' }else{ thediv.style.display='none' } } </script> This part its working: <input type=checkbox name=type value='1' onclick="return showhide('div1');">Submit - 1 <input type=checkbox name=type value='2' onclick="return showhide('div2');">Submit - 2 This part its not working <input type=checkbox name=type value='1' checked="checked" onclick="return showhide('div1');">Submit - 1 <input type=checkbox name=type value='2' onclick="return showhide('div2');">Submit - 2 how i can make if its already check input value 1 to show div1 but if i remove the checked to dont show anymore div1 thanks 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? 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;
}

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 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. 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) ?

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! Hi all can someone guide me (total JS newbie) on this presumably pretty easy task? I have a "parent" page with some text inputs in it (a form). This is what I am after: -when the user clicks a link it pops open a new window via JS - "child" (this is working). -in the "child" window there are also some text inputs (another form) (done). -when the user changes the value for 'testChild_textInput_4' in the child window, then I want it to automatically set this same value, to effectively overwrite, what is currently in 'testParent_textInput_2' in the parent window. Presumably this involves an onChange event, but it is also OK with me if the needful (the text input's value in the parent window being overwritten) happens upon the child window's form submit. If anyone can show me either trick, I would be thrilled! I set up a test page to make this all easy to talk about: http://www.yellow-turtle.com/testDumpMe_parent.html Please let me know! Thanks! -John Hi, my code below shows 2 radio buttons, when you click on one, it shows the content from a div, I would like to show the content of the checked radio button by default, at teh moment, they don't show any content until they are clicked!

I need to clear the default value from a textarea when a user clicks on the textarea and then replace it if the user clicks away from the textarea without modifying it. I have managed to accomplish this with the textfields in my forms but I am struggling to get the textarea element to mimic this behavior. Here is the script I am using: Code: addEvent(window, 'load', init, false);
function init() {
var formInputs = document.getElementsByTagName('input');
for (var i = 0; i < formInputs.length; i++) {
var theInput = formInputs[i];
if (theInput.type == 'text' && theInput.className.match(/\binput\b/)) {
/* Add event handlers */
addEvent(theInput, 'focus', inputText, false);
addEvent(theInput, 'blur', replaceDefaultText, false);
/* Save the current value */
if (theInput.value != '') {
theInput.defaultText = theInput.value;
}
}
}
}
function inputText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == target.defaultText) {
target.value = '';
}
}
function replaceDefaultText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == '' && target.defaultText) {
target.value = target.defaultText;
}
}
HTML: [HTML] <form action="#"> <fieldset> <legend></legend> <input type="text" value="Your Name" id="name" class="input" /> <label for="name">Name Required</label><br/> <input type="text" value="Your Email" id="email" class="input"/> <label for="email">E-mail Required</label><br/> <input type="text" value="Your Website" id="website" class="input"/> <label for="website">Website</label> <textarea rows="15" cols="71">Your Message Goes Here.</textarea> <input type="submit" value="Submit Comment" class="button" /> </fieldset> </form> [/HTML] I am really just trying to get this form to behave the way all other forms on the internet work- where text clears when a user clicks on a form element and replaces itself if the user doesn't enter new text. I have it working on the text field but no the textarea. Help! Is there a way to change the text from OK to CLOSE on an alert box ?
I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. Hi, I'd like to use the jQuery validation plugin as seen on the following example: http://docs.jquery.com/Plugins/validation#Example But it doesn't work properly if I use inline/in-filed labels. Any help is appreciated! Rain Lover Is there a method or a way to duplicate the text typed in one textarea to another, with onkeyup or onchange? The problem I'm facing is with FCKeditor. Two textareas with loaded templates and the text has to be manually copied and pasted when changed. Code: <form action="" method="post" name="form1" id="form1"> Subject:<br /> <input type="text" name="subject" value="Subject" size="32" /> <br /> Main Article:<br /> <textarea name="content" cols="50" rows="10"> <?php echo $row['article']; ?> </textarea> <br /> Text version:<br /> <textarea name="content_text" cols="50" rows="10"> <?php echo $row['article']; ?> </textarea> <input type="submit" value="Send" /> </form> I may be going about this all wrong? Send newsletters, it all works - not sure? do I need the second texarea. |
