JavaScript - Xml To Javascript Array Problem
Hey all, first, if I missed this in my search, I apologize. Now on to the problem at hand. I'm reading an xml file of html links into a webpage I'm building on the intranet. I have assigned each of a particular element of that xml file to a specific location within a javascript array. Then I built a second javascript array and assigned the value of the first array to second array using the .toString(); method.
Here's an example of what I've got so far: Code:
var linkArray = new Array();
linkArray[0] = (xmlDoc.getElementsByTagName("link")[0].childNodes[0].nodeValue);
linkArray[1] = (xmlDoc.getElementsByTagName("link")[1].childNodes[0].nodeValue);
linkArray[2] = (xmlDoc.getElementsByTagName("link")[2].childNodes[0].nodeValue);
linkArray[3] = (xmlDoc.getElementsByTagName("link")[3].childNodes[0].nodeValue);
linkArray[4] = (xmlDoc.getElementsByTagName("link")[4].childNodes[0].nodeValue);
linkArray[5] = (xmlDoc.getElementsByTagName("link")[5].childNodes[0].nodeValue);
linkArray[6] = (xmlDoc.getElementsByTagName("link")[6].childNodes[0].nodeValue);
linkArray[7] = (xmlDoc.getElementsByTagName("link")[7].childNodes[0].nodeValue);
var pageArray = new Array();
pageArray[0] = linkArray[0].toString();
pageArray[1] = linkArray[1].toString();
pageArray[2] = linkArray[2].toString();
pageArray[3] = linkArray[3].toString();
pageArray[4] = linkArray[4].toString();
pageArray[5] = linkArray[5].toString();
pageArray[6] = linkArray[6].toString();
pageArray[7] = linkArray[7].toString();
I have put documentDOTwriteln statements in at various places to test the values of both arrays to be sure they are the same and they are. Now, later in the code, I'm loading an iframe that targets a specific element of the second array for the page link. It does this through a variable called currentPage thus: theIframe.src = pageArray[currentPage]; where currentPage is previously assigned a value pointing to an element in the array. For example currentPage = 0;. I'm trying to replace the original code which looks like this and works: Code: var pageArray = new Array(8);
pageArray[0] = "html/chapters/chapter1_Introduction/chapter1.html";
pageArray[1] = "html/chapters/chapter2_Change-Location/chapter2.html";
pageArray[2] = "html/chapters/chapter3_Change-Manager/chapter3.html";
pageArray[3] = "html/chapters/chapter4_Change-Salary/chapter4.html";
pageArray[4] = "html/chapters/chapter5_Change-Assignment/chapter5.html";
pageArray[5] = "html/chapters/chapter6_Termination/chapter6.html";
pageArray[6] = "html/chapters/chapter7_Request-Access-to-MSS/chapter7.html";
pageArray[7] = "html/chapters/chapter8_Summary/chapter8.html";
with the contents of the xml file so I can load different pages into a template. I don't understand what I'm doing wrong. Can anyone point me in the right direction? I believe my xml is parsing correctly since I can do a documentDOTwriteln and see the contents when placed into an array. Am I wrong on this? Any and all help you can give is greatly appreciated! M Similar TutorialsI am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form. For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields. php array creation: Code: if ($row_locations)
{
while ($row_locations = mysql_fetch_assoc($locations))
{
$mail[$row_locations['comp_id']]=array('mailto'=>$row_locations['mailto'], 'madd'=>$row_locations['madd'], 'madd2'=>$row_locations['madd2'], 'mcity'=>$row_locations['mcity'], 'mstate'=>$row_locations['mstate'], 'mzip'=>$row_locations['mzip'], 'billto'=>$row_locations['billto'], 'badd'=>$row_locations['badd'], 'badd2'=>$row_locations['badd2'], 'bcity'=>$row_locations['bcity'], 'bstate'=>$row_locations['bstate'], 'bzip'=>$row_locations['bzip']);
}
}
javascript function - this should create the array and send variables to text fields. Code: function updateAddress() {
var mail = $.parseJSON(<?php print json_encode(json_encode($mail)); ?>);
{
if (comp_id in mail) {
document.getElementById('mailto').value=mail.comp_id.mailto.value;
document.getElementById('madd').value=mail.comp_id.madd.value;
document.getElementById('madd2').value=mail.comp_id.madd2.value;
document.getElementById('mcity').value=mail.comp_id.mcity.value;
document.getElementById('mstate').value=mail.comp_id.mstate.value;
document.getElementById('mzip').value=mail.comp_id.mzip.value;
} else {
document.getElementById('mailto').value='';
document.getElementById('madd').value='';
document.getElementById('madd2').value='';
document.getElementById('mcity').value='';
document.getElementById('mstate').value='';
document.getElementById('mzip').value='';
}
}
}
Where is this breaking? Thanks in advance. Hi, i can't find the mistake in my little script hope someone can help me. PHP Code: <?php /* -------------------- read thumbfolder -------------------- */ function isRdyPfD($filename){ if ($filename == '.' || $filename == '..') { // To-Top-Dir return false; } $ext = explode(".",$filename); $ext = $ext[sizeof($ext) - 1]; $allowedformats = array ( 'jpg', 'png', 'jpeg', 'gif' ); return in_array($ext,$allowedformats); } function getPicsfromDir($dir){ /* array with names of the pictures in $dir */ if (is_dir($dir)) { if ($dh = opendir($dir)) { $filearray = array(); while (($file = readdir($dh)) !== false) { if (isRdyPfD($file) === true) { $filearray[] = $file; } } closedir($dh); return $filearray; } } else { return false; } } // End Function $thumbs = getPicsfromDir("./images/thumbs/"); /* -------------------- thumbfolder -------------------- */ echo "<div id='thumbslider'>\n"; echo "<ul id='thumbs'>\n"; for($i = 0; $i < count($thumbs); $i++){ echo "<li><img src=\"./images/thumbs/$thumbs[$i]\" onclick=\"thumbClick($i)\" /></li>\n"; } echo "</ul>\n"; echo "</div>\n"; /* -------------------- big size images folder -------------------- */ $bigSizeImages = getPicsfromDir("./images/"); //print_r($bigSizeImages); $jsValue = ''; for ($j=0; $j < count($bigSizeImages); $j++){ $jsValue = $jsValue . $bigSizeImages[$j]; if ($j < (count($bigSizeImages)-1)) { $jsValue = $jsValue . ","; } } ?> <script type="text/javascript"> images = new Array(<?php echo $jsValue ?>); function thumbClick(pos){ //alert(pos); alert(images[pos]); } </script> I can't trace the images array values? thanks for a feedback!!! Hi, Here is a working code to copy 2d php array to 2d javascript array. Code: <html>
<head>
<?php
for($i = 0; $i < 3; $i++)

Hi, Can anyone help me with this question? I have a JavaScript page to place a track to a google maps. I want the array of points to be shown to come from PHP. However, there are (probably a lot) of errors in it that makes it doesn't work. My main page code: xmlhttpT=new XMLHttpRequest(); //var MyRouteC = ""; xmlhttpT.open("GET","getRoute.php",true); //var MyRouteC= (array)xmlhttpT.responseText; var MyRouteC = (array)xmlhttpT.responseText); xmlhttpT.onreadystatechange=function() { if (xmlhttpT.readyState==4) { //MyRouteC = xmlhttpT.responseText; alert(xmlhttpT.responseText); } } xmlhttp.send(); var MyRoute = new google.maps.Polyline({ path: MyRouteC, strokeColor: "#FF0000", strokeOpacity: 1.0, strokeWeight: 2 }); MyRoute.setMap(map); The page it is calling is a php page: PHP Code: <?php $con = mysql_connect("xxxxx.mysql","xxxxxxxxxxx","xxxxxxxxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("letsmeet_mobi", $con); $query = "SELECT * FROM CurrentLocation ORDER BY time DESC LIMIT 0 , 5"; mysql_query($query); $result = mysql_query($query); while($row = mysql_fetch_array($result)) { $output = $output . " new google.maps.LatLng(".$row['gpslat'].", ".$row['gpslong']."), "; } echo $output; mysql_close($con); ?> The php data connection works fine, and it results in a string that looks exactly like the way I want the value to be passed to the JavaScript. Any help is welcome! Hi guys, I am new to JavaScript and was wonder how I would go about creating a form to allow the user to enter various words, one at a time. These words are added to an array and displayed in the page using the textarea form element. Each time a new word is entered, it is added to the array, and then the array is sorted in alphabetical order before the words in the array are displayed in the textarea, one per line. I have tried lots and lots of different methods to accomplish this, and I can get it half working when I use the alert function, but I need this to display on the page in a textarea rather than in an alert box, I tried to get it to write to the page using a document.write function, but like I said i am new to JavaScript and unfortunately cant get any of it working.

If someone could please help me by posting some relevant code that would accomplish this, I would greatly appreciate it, as so far I have been scratching my head for a few hours. Thanks, ~Savage Hi, I am trying to create an array to pass to JQuery, but after several hours of trying, am falling over. I am trying to use Ajax to populate the javascript FullCalendar. I am trying to pass an arry to the following property: This works: $('#calendar').fullCalendar({ events: [{"id":1112,"title":"Event1","start":"2009-10-10"},{"id":222,"title":"Event2","start":"2009-10-20","end":"2009-10-22"}] }; something like: $('#calendar').fullCalendar({ events: MyJSArray() }; I will be using AJAX to populate MyJSArray(). I have tried the likes of: MyJSArray = new array("id"=>112,"title"=>"Event1", etc); But no joy I don't know how to get a javascript array into that format. I have my database values, but I need to put them into a format that the "Event" will accept. I have used PHP and arrays fine, but coming to grips with JS arrays,etc are a bit finiky at the moment. I am a little stuck, any help or points in the right direction will be much appreciated. Thanks Blueevo. Forgive me if the code is rather bad, I am new to Javascript. Now what I'm aiming to do is after I have entered the contents of the Array's I then want to query the newly created array/database, based on the track number, Via a seprate function. However all the values I entered, always come up empty. No matter how many solutions I tried I can't get the query to work. So I've decided to come to you guys/gals for help. Code: mainMenu()
function mainMenu()
{
menu = 0;
menu = eval(prompt("Select an Operation to Continue\n ====================\n 1 - Create new Database\n 2 - Query Database\n 3 - Show Report\n Any other to exit"));
switch (menu)
{
case 1:
insert(trackNumber)
break;
case 2:
query(trackNumber)
break;
case 3:
break;
}
}
// Enter the track number
function trackNumber()
{
var theNumber = eval(prompt("Enter Track Number"));
if ((theNumber >= 0) && (theNumber < 100))
{
return theNumber; // Stores the track number for insert(trackNumber)
}
}
// This function will allow the user via the (trackNumber)
// parameter to insert the contents of the database
function insert(trackNumber)
{
// Create new Array's
trackNum = new Array(5)
trackName = new Array(5)
trackArtist = new Array(5)
// For each Track we want to hold the trackNumber(),
// the track name and the track's artist.
for(var i = 0; i < trackNum.length; i++)
{
trackNum[i] = trackNumber()
trackName[i]= prompt("Enter Track Name: " + i)
trackArtist[i] = prompt("Enter Track Artist: " + i)
}
}
// This Function will allow the user to query the database, based on track number.
function query(trackNumber)
{
var trackSearch = trackNumber()
var j = 0;
for(j in query)
{
if (query[j] == trackSearch)
{
alert("Track Number: " + trackSearch + "\nTrack Name: " + trackName[j] + "\nTrack Artist " + trackArtist[j]);
break;
}
else if (query[j] != trackSearch)
{
alert("Track Number: Empty" + "\nTrack Name: Empty" + "\nTrack Artist: Empty");
break;
}
}
}
If someone could please help me by posting some relevant code that would help accomplish this, I would greatly appreciate it, as so far I have been scratching my head puzzled, at how I could solve this. Hello all, There's this javascript array on an html page, with some gifs in it. How can I include swfs in this array? Here's the code: <script type="text/javascript"> var imageArray = new Array(); imageArray[0] = "images/animation9.gif"; imageArray[1] = "images/Title2.gif"; imageArray[2] = "images/animation4.gif"; function doIt() { var rand = Math.floor(Math.random()*3); var imgPath = "<img src='"+imageArray[rand]+"' alt='Welcome to Kabeoke' border='0' align='absmiddle' />"; document.getElementById("image").innerHTML = imgPath; } </script> Thank-you SO much in advance Sorry folks, Im not sure that I am using the correct terminology here. What i would like to do is sort an array based on the [SortBy] value, however this array is nested. For instance: ar.[SortBy]"PartNumber" ar.[0].[PartNumber]"123" ar.[0].[PartName]"Widget1" ar.[1].[PartNumber]"345" ar.[1].[PartName]"Widget2" ar.[2].[PartNumber]"456" ar.[2].[PartName]"Widget3" ar.[3].[PartNumber]"567" ar.[3].[PartName]"Widget4" Thanks! Hey all, I read this tutorial about creating javascript tabs: http://www.elated.com/articles/javascript-tabs/ Now basically there is a tabLinks array (var tabLinks = new Array(). There is a variable called id, which is assigned the value of the href attribute of a link ( we are looping through an array of links and tabLink represents the current link). In the code, there is a line: Code: "tabLinks[id] = tabLink; So id refers to the href attribute value of the link (without a hash) and tabLink is the link itself. tabLinks is the array. My question is are both the attribute and the link itself getting indexed at position 0 of the array, for example? Or is just the link getting indexed? If so, then why have this: [id]? I can't imagine that they are both getting indexed at position 0: [about a]. But if it's just the id getting indexed [about], then why are we assigning the link to this specific index? As you can tell, I'm really confused about how this indexing is working. Thanks for any response. hi.. I want to have a list of words (in an array or whatever just to work) if the user put that word in a textfield (onblur or onchange) a message popup (alert) appears.

Hi guys I was wondering if its possible to add contents within a div to a javascript array. Something like this: Code:
<script type="text/javascript">
function returnArray()
{
var divContent = document.getElementById('images');
var matchImage = divContent.match(/<img/);
/* add images into array somehow */
alert('This is ' +ImageArray[1]);
}
</script>
<div id="images">
<img src="image1.jpg" alt="image" />
<img src="image2.jpg" alt="image" />
<img src="image3.jpg" alt="image" />
</div>
Thanks for any info. Hello, I have just started learning JavaScript, so I do not know much about it at this moment. I need some help regarding validation of input values which are actually in an array. Okay, my HTML looks like this: Code: Link# 1: <input name="url[]" size="80" type="text"> Title# 1:<input name="title[]" size="80" type="text"> Link# 2: <input name="url[]" size="80" type="text"> Title# 2:<input name="title[]" size="80" type="text"> Link# 3: <input name="url[]" size="80" type="text"> Title# 3:<input name="title[]" size="80" type="text"> . . . . . And so on. (up to 20) User can add more input fields by adding "Add" button; I'm using JavaScript for that purpose. By default, only a couple of fields is shown. I want to validate these all fields using a loop or a number of loops, such that an alert appears if any field is left blank and also if any value in title[] array matches another value in that array and same for the second array url[] Examples of working would be something like this: Code: If Link# 1 is left blank: alert("Link# 1 is empty");
or
If Link# 2 is left blank: alert("Link# 2 is empty");
or
If Title# 1 is left blank: alert("Title# 1 is empty");
or
If Title# 2 is left blank: alert("Title# 2 is empty");
or
If Link# 1 == Link# 2: alert("Link# 1 is same as Link#2");
or
If Link# 1 == Link# 3: alert("Link# 1 is same as Link#2");
or
If Title# 1 == Title# 3: alert("Title# 1 is same as Title#3");
etc, etc.
