JavaScript - Populating Textarea
I am fairly new at Javascript, but there is something happening I do not understand. Please someone explain it to me and help with a solution.
In the function, I pull data from an URL and I have done this with several different data fields and populate the HTML input, option, and check boxes with no problem with the following method. Code: document.getElementById("othertxt").value=strValue;
document.getElementById("radsig").checked=true;
document.getElementById("eventtime").value=strValue;
But for some reason this method for textarea does not work and I know that there is a value in strValue because check it right before the line of code. Code: document.getElementById("othertxt").value=strValue;
Is textarea just treated differently? I have searched the internet and seen examples but for some reason I can not find the correct solution. Similar TutorialsHi Guys, I am trying to populate a textarea using a dropdown menu. The code I have tried doesn't seem to work, can anyone help? Code: <script type="text/javascript">function updateTextBox(val)
{
if(val == "1")
{
document.forms['myForm'].elements['myTextBox'].value = "something";
}
else if(val == "2")
{
document.forms['myForm'].elements['myTextBox'].value = "something else";
}
}
</script>
<form name="myForm">
<select onchange='updateTextBox(val)'>
<option></option>
<option value="1">1</option>
<option value="2">2</option>
</select>
Changing this drop down should change this text area....
<textarea name="myTextBox"></textarea>
</form>
Any help is much appreciated. Thanks. Hi, am trying to populate my second list box from the 1st.

Select City- (Like - New Delhi , Mumbai ,Kolkata ,Chennai) 2. Select Cinema(Hall Name) - ( Saket - New Delhi , South Ex. - New Delhi, Navi Mumbai - Mumbai , Salt Lake - Kolkata) 3. Select Movie- (Atleast 3 movies in each cinema nd somtimes it can more or less hall by hall ) 4.Select Date - (next 5 days of current date for advanced booking) 5. Select Time - (show time for each movie in each hall should be 3 shows, means if 3 movies are playing currently in 1 cinema thn we hav to mention show times with some difference for all 3 movies. ) 6.Select Price - ( price can b d same for all movies like - 150 (normal),250 (middle ) , 500 (high) ) 7.

Does anyone have any idea what I need to perform this action?
Hi I've been working on a listbox full of employees for our company intranet. Each name has an onchange tag that calls up a floor map and that part works fine but I'd really like to populate the names from an XML list so it's easier for non-IT people to maintain. I've been doing alot of web searches on the subject which comes up alot but it's mostly just fragments of what I need being that I've got no javascript background. I found a helpful tutorial on javascriptkit but that wasn't for creating listboxes so I'm only part of the way there. This is the XML file I've got (there will eventually be 400 entries): <?xml version="1.0"?> <list> <employee> <name>##########</name> <office>1656</office> <officePH>(403)000-0000</officePH> <mobile>N/A</mobile> <email>##########</email> </employee> <employee> <name>#########</name> <office>1657</office> <officePH>(403)000-0000</officePH> <mobile>N/A</mobile> <email>###########</email> </employee> </list> The most important parts are the name which will be used as the text of the box and the office number which will determine which floorplan is displayed. I added the other information so I can potentially put it in a div display later but that can wait. Can anyone help point me to some good resources on this subject? Thanks. I am having a hard time figuring this out, I have two simple arrays and I want to populate one by asking a visitor to enter information, it goes something like this... Code: var country = new Array(5);
c_list[0] = "USA";
c_list[1] = "UK";
c_list[2] = "France";
c_list[3] = "Germany";
c_list[4] = "Spain";
var president = new Array(); // Last name only
president[0] = window.prompt("President of USA?", ""); // Obama
president[1] = window.prompt("Prime Minister of UK?", ""); // Brown
president[2] = window.prompt("President of France?", ""); // Sarkozy
president[3] = window.prompt("Prime Minister of Germany?", ""); // Merkel
president[4] = window.prompt("President of Spain?", ""); // Zapatero
Now the question is, how do I use a simple for loop to use the names entered and populate the second array? Any help would be very kindly appreciated. Thank you I need to pull a date from a database that is already in the correct format of YYYYMMDDHHMMSS and create a javascript new Date() so that it can be used for comparing time elapsed. I have no issue with getting the date from the db and formatting it correctly but when inserted into new Date() it doesn't work. I have it working hard coded in the javascript but would like to replace the date with a value from a database instead of having it hard coded. current javascript is: var today=new Date(); var then=(new Date(2012,03,09,12,00,00,00); var mSeconds=today.getTime()-then.getTime(); what I would like to do: var today=new Date(); var then=(new Date(<?php echo $tou; ?>); var mSeconds=today.getTime()-then.getTime(); $tou is already formatted as 2012,03,09,12,00,00,00 with commas all other variables being pulled from the db work correctly. Hi i have a problem, i've been trying to fix this for the whole day pls see my code below Code: for ($o = 0; $o <= $totalclass; $o++)
{
for($i = 1; $i <= 45; $i++)
{
if ($_SESSION['classification'][$o] == $i)
{
$sql2="SELECT ClassDesc FROM tblclass WHERE ClassID = '$i'";
$result2=mysql_query($sql2);
// If successfully queried
if($result2)
{
while ($row2 = mysql_fetch_assoc($result2))
{
$ClassDesc2 = $row2['ClassDesc'];
}
}
//echo $ClassDesc2;
?>
<tr>
<td bgcolor="FAFAF6" class="small" valign="top">Class <? echo $i; ?></td>
<input type="hidden" name="<? echo "classid[]"; ?>" value="<? echo $i; ?>">
<td bgcolor="FAFAF6">
<textarea name="<? echo "specification[]"; ?>" COLS="50" ROWS="6" class="small" wrap="virtual" tabindex="<? echo $i; ?>"><? echo $ClassDesc2;?></textarea>
<input type="button" value="Reset" onclick="window.reset();" name="reset">

i've trying to create a button or image to reset one textarea (from whole array) and so far i've been unsuccessful. i've seen this on other website and i know it is possible to do this, pls help! Hello, I'm trying to populate an HTML drop down list with data from an XML file but have failed miserably so far using examples I've found. Please help. Thanks, Richard Hello. I would like text fields in an Adobe form to auto-populate when an item from a combo box list is selected. For example, if a user selects "shirt," then a set of text fields will auto-populate with the budget figures for a "shirt." I am not familiar with JavaScript. Would anyone be willing to explain the first steps in the project described above? Is there a way I could adapt previously-used scripts and insert my own information? Thank you in advance for your guidance. Hello. I have a problem here I have this menu: Code: <script language="JavaScript">

And I have a database with 3 fields: id, name and contents. These are the pages. Basically I want to do a select on the mysql database using PHP and populate the menu from the database. Can you tell me how to do this? Thanks Hi all, I am trying to find out if it's possible to auto populate a text input based on the value of another. e.g. there is an input called name.. the user completes this and enters something like John, then in the same form there is another input called username. Once the person enters John in the name field, the username automatically displays John. I'm not sure how doable this is, I'm not very familar with Javascript, so any advice would be greatly appreciated. Many thanks, Greens85 http://www.javascriptkit.com/javatut...rnalphp2.shtml Anyone have a decent way of adding a fade affect to this script? <html> <script language="javascript"> function foo() { var mainDiv = document.getElementById("my"); var div = document.createElement("div"); for(j=0;j<5;j++) { var select = document.createElement("select"); for(i=0;i<5;i++) { var option = document.createElement("option"); option.text = "hmm"; select.appendChild(option); } div.appendChild(select); } mainDiv.appendChild(div); } </script> <body> <select onchange="foo()"> <option>a</option> <option>b</option> <option>c</option> <option>d</option> <option>e</option> <option selected>-----Select------</option> </select> <div id="my"></div> </body> </html> I stuck ... but I got the solution now I want to reset on every selection ? Hello there . Here is my simple code Quote: <html> <head> <script> function addText(){ document.getElementById("textarea").value+=document.getElementById("text").value+'\n'; document.getElementById("text").value=""; document.getElementById("text").onblur=document.getElementById("text").value=" Your Message..."; } </script> <style> #textarea{background-color:#F3F3F3; } </style> </head> <body> <form> <TEXTAREA id="textarea" COLS="80" ROWS="20" ></TEXTAREA><br/><br/> <input type="text" id="text" name="text" value=" Your Message..." onclick="this.value=''" size="96"> <input type="button" value="Send" name="submit" onclick="addText()"> </form> </body> </html> My problem is I dont know what to do iorder to make my send button to push the text entered in the text field from bottom to the top (not from the top to the bottom) Hi all, I'm loading external xml and displaying specific tagged elements in a textarea. It works fine in IE because I can turn the variable object into text with a simple object.text property, but in Firefox (using the serializeToString method), the object appears in my textarea tags and all. The code looks something like this (this is just a dummy script - imagine the xml is already loaded into the object xmlDoc ): Code: function writePage(){
document.write('<textarea name="inputText">'+myText+'</textarea>');
}
function xmlIsLoaded(){
if(window.ActiveXObject){ //tests for IE
myText = xmlDoc.getElementsByTagName("desiredTag")[0].text;
} else { //tests for FF
myText = (new XMLSerializer()).serializeToString(xmlDoc.getElementsByTagName("desiredTag")[0]);
}
writePage();
}
What am I missing here? I've tried toString, textContent, innerText, childNodes - just about everything I can think of to get just the text w/o the tags from the xml for the FF version. Any thoughts? ~gyz I found a script that is perfect for my need but it is written for forms textareas and I can seem to get it to work textareas that are not wrapped in form. Code: Code: <script>function insertAtCursor(sTag,eTag)
{
var obj = document.form.message;
var strPos;
var ie_strPos;
var oSel;
obj.focus();
strPos += sTag.length + eTag.length;
ie_strPos += sTag.length + eTag.length;
if (document.selection && document.selection.createRange) { // Internet Explorer
oSel = document.selection.createRange();
if (oSel.parentElement() == obj) {
oSel.text = sTag + oSel.text + eTag;
ie_strPos += oSel.text.length;
}
oSel.moveStart ('character', ie_strPos);
oSel.moveEnd ('character', 0);
oSel.select ();
}
else if (typeof(obj) != "undefined") { // Firefox
var longueur = parseInt(obj.value.length);
var selStart = obj.selectionStart;
var selEnd = obj.selectionEnd;
obj.value = obj.value.substring(0,selStart) + sTag + obj.value.substring(selStart,selEnd) + eTag + obj.value.substring(selEnd,longueur);
strPos += txtarea.value.substring(selStart,selEnd).length;
obj.selectionStart = strPos;
obj.selectionEnd = strPos;
obj.focus ();
}
else obj.value += sTag + eTag;
obj.focus();
} </script>
<button onclick="insertAtCursor('[blah]','[/blah]')">Test</button>
<form method="post" name="form" action="">
<textarea name="message" cols="50" rows="10"></textarea>
</form>
My textarea: Code: <textarea id="new_topic_text" class="new-topic-subject-text elastic" style="overflow: hidden;"></textarea> I'm having trouble with the way my textarea is displaying text when it's submitted. It always comes out as one line of text instead of the way a user has entered it. Here's my code. Code: <textarea name="info" value="" rows="7" cols="55"> Enter Your Personal Information Here </textarea><br /><br /> That is then called to a function which displays it in a new page. Code: <script>
function buildResume()
{
resInfo = document.myResume.info.value
flyWindow = window.open()
flyWindow.document.write("Personal Information " + resInfo);
}
</script>
If any knows how I could fix this it'd really help. I've tried using the pre element and wrap property with no luck. |
