JavaScript - Help With Array
Code:
<html>
<head>
<script type="text/javascript">
<!---
var Jane=new Array ("Female","Red","Lipstick","28",","45789546");
var Mary=new Array ("Female","Orange","Lipstick","25",","45789547");
var Elle=new Array ("Female","Blue","Lipstick","21",","45789548");
document.write(Jane[0]);
document.write(Jane[1]);
document.write(Jane[2]);
document.write(Jane[3]);
document.write(Jane[4]);

Please help me with the above code. I would like to have a prompt so I can enter one of the three girls name (array) then it would display all the elements. For example: Enter a name: Jane the output would be : Female Red Lipstick 28 45789546 Please help. Thank you very much. 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. I have the following array that contain the people who are on off on certain time: Code: var all = [
["1234", "Jim", "2011-10-23 00:00:00", "2011-10-25 07:00:00"],
["1235", "Jack", "2011-10-21 00:00:00", "2011-10-21 08:00:00"],
["1236", "Jane", "2011-10-11 00:00:00", "2011-10-11 00:30:00"],
["1237", "June", "2011-10-20 00:00:00", "2011-10-20 12:00:00"],
["1238", "Jill", "2011-10-14 00:00:00", "2011-10-14 11:00:00"],
["1239", "John", "2011-10-16 00:00:00", "2011-10-16 10:30:00"],
["1240", "Jacab", "2011-10-19 00:00:00", "2011-10-20 08:30:00"]
];
The above array, I wish to use javascript to insert into the FullCalendar (http://arshaw.com/fullcalendar/). I notice that the only way seems to be using the FullCalendar array style (or structure) as follows: Code: $('#calendar').fullCalendar({
events: [
{
title : 'event1',
start : '2010-01-01'
},
{
title : 'event2',
start : '2010-01-05',
end : '2010-01-07'
},
{
title : 'event3',
start : '2010-01-09 12:30:00',
allDay : false // will make the time show
}
]
});
So, the question is: How do I insert my array to match with the FullCalendar array? cause FullCalendar array had a different array structure from my array - and I don't think so that I can write in this way: Code: $('#calendar').fullCalendar({
events:all
});
Appreciate any help provided. Hey guys, I'm hoping this is possible or that there is an easier way to do this. I'm having an issue with displaying data from one array that contains information about users in a table that is controlled by a different array. Is it possible to do this or is this use of arrays to display the data the wrong approach? The table is located on one webpage, I simply want to extract one piece of information that I have placed in the initial array as part of the login script that contains user information (for validation for login etc) and display it in a table on the new webpage that is opened as a result of successful validation of the user details. I'm completely stumped and after many attempts I just can't seem to get it to work. I can't seem to figure out how to accomplish this. In my website, I would like the user to input text into a single or multiple textbox(es) and then have the contents of the textbox(es) stored to either a variable or an array. Then I would like to have that variable/array compared to other arrays. Basically, the user is searching for items in a database. The user can search for as many or as little items as they want. Then the item(s) will be compared to multiple arrays to find out if what the user wants is in the database. So for example, let's say the user is searching for recipes that have all or part of these ingredients: chicken, broccoli, lemon, honey. So, there would have been a total of 4 textboxes...one for each ingredient. These ingredients are stored to an array..lets call it ingredient(). In the database of recipes, each recipe has its own array which includes the ingredients needed to make the recipe, we'll call them tag1(), tag2(), and tag3(). Now, I want the array, ingredient(), to be compared to each of the "tag" arrays to see if any of the "tag" arrays include exactly match the ingredient() tag in part or in whole. Is this possible? 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 .

Hi, In a nutshell,can anyone tell me how to copy a 2d (two dimensional ,2 dimensional) php array to 2d javascript array?I would be obliged if anyone can provide me a method of doing that OR I have written a code to copy a 2d php array to a 2d javascript array.It is working but there is one problem(please see the following).Can anyone tell me what I am doing wrong here? The 2d php array is $quest[100][6] and the 2d javascript array is questions[100][6] . I have written the javascript code inside the <?php....?> itself using echo "<script language="javascript" type="text/javascript">.......</script>; Now ,inside the javascript,when I try to copy the 2d php array to the 2d javascript array using the following method it works questions[0]= ["<?php echo join("\", \"", $quest[0]); ?>"]; questions[1]= ["<?php echo join("\", \"", $quest[1]); ?>"]; ... and so on However, if I try to do the same using the following method it does not work for (var i= 0; i <= 99; i++) { questions[i]= ["<?php echo join("\", \"", $quest[i]); ?>"]; } Why is that?What mistake am I making?Any help will be deeply appreciated.Thanks -----------------------------THE CODE------------------------------------ <?php Access database and store result of mysq_query in $result....... $result = mysql_query($query); for ( $count = 0; $count <= 99; $count++) { $quest[$count]=mysql_fetch_array($result,MYSQL_NUM);; } echo "<script language="javascript" type="text/javascript"> var questions = new Array(100); for (var i = 0; i <100; i++) { questions[i] = new Array(6); } /*The following method of copying 2d php array to 2d javascript array is not working for ( var i = 0; i <= 99; i++) { questions[i]= ["<?php echo join("\", \"", $quest[i]); ?>"]; } */ /*The following method ,however,is working*/ questions[0]= ["<?php echo join("\", \"", $quest[0]); ?>"]; questions[1] = ["<?php echo join("\", \"",$quest[1]); ?>"]; questions[2] = ["<?php echo join("\", \"",$quest[2]); ?>"]; ....and so on </script>"; mysql_close($db_server); ?> Hi, Here is a working code to copy 2d php array to 2d javascript array. Code: <html>
<head>
<?php

I'm kind of new to Javascript, I need to open a text file from an external server, store each line in an array, then search that array for a certain word (HIGH), and if it exists then write something to the webpage, and if not, write something else. Here is what I have so far: Code: <html>
<head>
<title>Test</title>
<script>
<!--

var wxd1array = wxd1txt.responseText.split("\n"); // Will separate each line into an array
var wxd1high = wxd1array.toString(); //Converting the String content to String
//var highsearchreg = new RegExp("HIGH");
//var wxd1high = wxd1array[x].search(highsearchreg);
document.write(wxd1high);
if (wxd1high.search("HIGH") >= 0){
document.write("HIGH RISK");}
else {
document.write("NO RISK");}

When added to a webpage, nothing shows up except the "Hi!" and there are no errors in the Javascript Console in Google Chrome. Is this possible with Javascript, and if so, what am I doing wrong or not doing? Also, I have 2 URLs, one is a text file that has the HIGH text I want for an example, the other is the current file, which shouldn't have HIGH in it (unless the weather in the US turns really bad) Hello I'm have some javascript objects with arrays that should be transferred as php array. Its posted by ajax httpRequest. How can I return php array, from the javascript? JS Code: ['asd1', 'asd2', 'asd3'] via Ajax => PHP PHP Code: array('asd1', 'asd2', 'asd3'); Hi, i have an input value array for customer ids, i also need to make a copy of that array into another input element on submit to use for another process. So far here is what i have come up with regarding the js the current html is this Code:
<!-- original input -->
<input id="cb<?php echo $i;?>" name="cid[]" value="<?php echo $commissions[$i]['id'];?>" onclick="isChecked(this.checked);" type="checkbox" />
<!-- this is new html input which is outside the $i loop that i need a copy of cid[] stored on submit
<input type="hidden" name="ids[]" onsubmit="valueTovalue();" />
<!-- here is the js so far -->
<script type="text/javascript">
function valueTovalue()
{
var valin = document.adminForm.cid.value; //cid is the array cid[]
document.adminForm.ids.value = valin; //copy the array to the new input element array ids
}
</script>
so basically if they click 1 cid then ids will also show 1, if they click all cid then ids will show all as well. will that work the way i have it, am i even close here.. thanks update: what i have seems to work fine for text values or string values but not for arrays, what am i missing that it wont copy an array? Array ( [cid] => Array ( [0] => 1 ) [task] => remarksonly [remark] => hhhyyy [boxchecked] => 1 [ids] => Array ( [0] => ) ) am i getting closer lol Code:
function valueTovalue()
{
var valin = cid.concat;
document.adminForm.ids.value = valin.concat;
return(true);
this has to be close i hope Code: document.adminForm.ids.value = [].concat(document.adminForm.cid); I'm trying to find Array's with the Cities of U.S. States (respectively) built. I.E. Alabama - Abbeville Abel Abernant Acmar Adamsville etc....for all 50 states. Does such an Array already exist? this might be PHP as well, so I apologize if this isn't the proper location to post just such things. Sorry if this question sounds dumb but I'm a JS noob. Basically I need to create a script that will take three numerical grades entered from a prompt, as well as the student's fictitious name; then take the average of the highest and lowest grades. So far I've gotten it to: Accept then display the student's name Take three grades then figure out and display the average of all three. I still need it to: Calculate and Display the average of the highest and lowest scores Display all three scores that were entered I assume that I'll have to instantiate an array, then input values from the prompt, but everything I have tried has failed. See my script below. <script type = "text/javascript"> <!-- var gradeCounter, gradeValue, total, average, linebreak = "<br />", name, grade; total = 0; gradeCounter = 0; name = window.prompt("Input Student Name") grade = window.prompt( "Input Numerical Grade, -1 to Quit:", "0" ); gradeValue = parseInt( grade ); while ( gradeValue != -1 ) { total = total + gradeValue; gradeCounter = gradeCounter + 1; grade = window.prompt("Input Grade, -1 to Quit:", "0"); gradeValue = parseInt( grade ); } if ( gradeCounter != 0 ) { average = total / gradeCounter; document.write(name) document.write(linebreak) document.write("Average: " + average); } else document.write( "<p>No grades were entered</p>" ); // --> </script> Hi, today I am creating a form where a user can enter prices for things. I want to use javascript to display a total so far and it should update automatically as the user enters/changes new prices. I have a form which looks something like this: Code: <form method="post" action="mailer.php" name="contact"> Price 1 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> Price 2 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> Price 3 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> Price 4 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> Price 5 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> Price 6 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> Price 7 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()"> <br> Total <input type="text" name="grand" readonly="yes" id="grand"> </form> Here is my javascript function, calculate_total(): Code: function calculate_total() {
var all = document.getElementsByName("stampprice[]");
var total = 0;
for (i=0; i <= all.length; i++) {
var price = document.getElementsByName("stampprice[]")[i].value;
var total = total + price;
}
document.getElementById("grand").value=total;
}
When I change the values in the price fields, nothing happens. I also tried putting javascript:calculate_total(); in the address bar, but still, it doesn't work. Help? So if I create an array like below how can I test whether the value in "field1" is in the array? var field1 = document.theForm.car.value; var myCars = new Array(); var myCars=["Saab","Volvo","BMW"]; I'm calling a function that I want to loop thru an array, check the values and disable the drop down accordingly. Code: function toggleSelect() {
var selBox = new Array(4);
selBox[0] = document.getElementById('wcsave_10_session_mconc1');
selBox[1] = document.getElementById('wcsave_10_session_mconc2');
selBox[2]= document.getElementById('wcsave_10_session_aconc1');
selBox[3] = document.getElementById('wcsave_10_session_aconc2');
for (var i = 0; i < selBox.length; i++){
if (selBox[i].selectedIndex !=0 ) {selBox[i].disabled = true;}
else {selBox[i].disabled = false;}
}
}

I keep getting a selBox[i] not defined. Is it the xxx[x] = ? Hi, I want to create a javascript array from a php array. At the moment, when my page loads, is loads a file called sso.js, which contains the following js array: var customarray=new Array('Bournemouth University', 'Cambridge Imaging Systems (CIS)', 'Glasgow Metropolitan College', 'Royal Holloway, University of London', 'University of Portsmouth', 'University of Brighton', 'Esher College', 'Canterbury Christ Church University', 'British Universities Film and Video Council (BUFVC)', 'Eduserv'); What I want to happen is that this array is created from a php string/ sql database. At the moment I have created a php string which has all the values in the array. Ie: <?echo $entityIDstring;?> Outputs 'Bournemouth University', 'Cambridge Imaging Systems (CIS)', 'Glasgow Metropolitan College', 'Royal Holloway, University of London', 'University of Portsmouth', 'University of Brighton', 'Esher College', 'Canterbury Christ Church University', 'British Universities Film and Video Council (BUFVC)', 'Eduserv' How can I put $entityIDstring into the javascript customarray automatically? I tried using: <input type="hidden" name="entityIDstring" id='entityIDstring' value="<?=$entityIDstring?>"/> In the page but when I tried: var customarray2 = document.getElementById('entityIDstring'); alert(customarray2.value); In the js, nothing happens. Im trying to create a 2d array with these two rows - Example1, Example2, Example3 Example4, Example5, Example6 To print I use this for loop- Code: for(i = 0; i < 2; i++)
{
for( j = 0 ; j < 3; j++)
{
document.write(array[i][j]);
}
}
I dont Understand how to create the actual 2d array though. Can someone please shed some light on the situation. Thanks alot Hi, I'm trying to create a sort of database, consisting of an empty array, within which/for each i, there is an associative array of 3 properties. In other words, a empty muti-dimensional associative array... I'm having issues inputting into this second layer - I'm possibly getting confused with arrays, objects, functions... Code: var dbase = new Array()
for(i in dbase)
{
dbase[i] = [ artist, name, url ]
dbase[i].artist = ("Please enter the artist's name")
}
OK so I am trying to put together a function that takes an array and then takes the square root of each number in old array and writes to the screen the new array of squared numbers. Not looking for answer, just what I need to do for the logic in the for statement.
Hi, im new to the javascript side of things, could someone point out where im going wrong in this array: Code: $("*").each(function(i){
var elements = new Array(5);
if($(this).attr("class")!="nbta"){
var borderStyle = $(this).css("border");
if(borderStyle==""){
$(this).attr("style", "border:3px solid transparent;");
}
}
elements[i]['id'] = $(this).attr("id");
elements[i]['x'] = Left($(this));
elements[i]['y'] = Top($(this));
elements[i]['width'] = $(this).width();
elements[i]['height'] = $(this).height();
});
alert(dump(elements));
firebug says - Quote: elements[i] is undefined file:///C:/wamp/www/test/test.html Line 67 |
