JavaScript - Copy 2d Php Array To 2d Javascript Array
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); ?> Similar TutorialsHi, Here is a working code to copy 2d php array to 2d javascript array. Code: <html>
<head>
<?php
for($i = 0; $i < 3; $i++)
{
for($j = 0; $j < 2; $j++)
{$quest[$i][$j] = $i*10+$j;}
}
?>
<script type="text/javascript">
var questions = new Array(3);
for (var i = 0; i < 3; i++)
{
questions[i] = new Array(2);
}
questions[0] = ["<?php echo join("\", \"", $quest[0]); ?>"];
questions[1] = ["<?php echo join("\", \"", $quest[1]); ?>"];
questions[2] = ["<?php echo join("\", \"", $quest[2]); ?>"];
document.write(questions[0][0] + "<br />");
document.write(questions[0][1] + "<br />");
document.write(questions[1][0] + "<br />");
document.write(questions[1][1] + "<br />");
document.write(questions[2][0] + "<br />");
document.write(questions[2][1] + "<br />");
</script>
</head>
</html>
Now,here's the thing.Notice these lines in the code questions[0] = ["<?php echo join("\", \"", $quest[0]); ?>"]; questions[1] = ["<?php echo join("\", \"", $quest[1]); ?>"]; questions[2] = ["<?php echo join("\", \"", $quest[2]); ?>"]; I would like to put these lines in a loop,something like for (var i = 0; i < 3; i++) { questions[i] = ["<?php echo join("\", \"", $quest[i]); ?>"]; } But even after a lot of efforts I am unable to do so,what am I doing wrong?Thanks 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 $i loop that i need a copy of cid[] stored on submit
<input type="hidden" name="ids[]" onsubmit="valueTovalue();" />
<!-- here is the js so far -->
<script type="text/javascript">
function valueTovalue()
{
var valin = document.adminForm.cid.value; //cid is the array cid[]
document.adminForm.ids.value = valin; //copy the array to the new input element array ids
}
</script>
so basically if they click 1 cid then ids will also show 1, if they click all cid then ids will show all as well. will that work the way i have it, am i even close here.. thanks update: what i have seems to work fine for text values or string values but not for arrays, what am i missing that it wont copy an array? Array ( [cid] => Array ( [0] => 1 ) [task] => remarksonly [remark] => hhhyyy [boxchecked] => 1 [ids] => Array ( [0] => ) ) am i getting closer lol Code:
function valueTovalue()
{
var valin = cid.concat;
document.adminForm.ids.value = valin.concat;
return(true);
this has to be close i hope Code: document.adminForm.ids.value = [].concat(document.adminForm.cid); I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form. For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields. php array creation: Code: if ($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.

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'); Hello hello, I have a javascript array to load a different picture each time a page loads up. The code is as follows: <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' border='0' align='absmiddle' />"; document.getElementById("image").innerHTML = imgPath; } </script> So...it works fine with .gifs, but how would I get it to work with .swf movies too? I've tried just putting the .swf in there e.g. ... 'imageArray[2] = "images/animation6.swf"; But that doesn't seem to work. Any ideas? Thank-you SO much in advance. 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! PLEASE help me with this I have no hair left!

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 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? 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 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. I have a code that I implemented on my site. I was wondering if there was a way to had an active link within the 'blurb' section? I'm not familiar with Javascript... var blurb = new Array(); blurb[0]="Text 1" blurb[1]="Text 2" blurb[2]="Text 3" blurb[3]="Text 4" blurb[4]="Text 5<br>More text<br>Add a link" blurb[5]="www.link.com" for (i=0; i < aryImages.length; i++) { var preload = new Image(); preload.src = aryImages[i]; } function swap(imgIndex) { document['imgMain'].src = aryImages[imgIndex]; TheText = blurb[imgIndex]; document.getElementById('blurbarea').innerHTML=TheText; } Any help would be great!! 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.
Any help would be appreciated. Thank you. Hi, New to javascript here. I'm trying to do something that would be very easy to do in php, but is quite hard in javascrpit due to the lack of support of associative array. PHP Code: var myArray = new Array(); //a click event has been detected //var clickedElementId = get the clicked element id... myArray[clickedElementId ] = true; And if the element gets clicked again: PHP Code: if(isset(myArray[clickedElementId ])){ unset(myArray[clickedElementId ]); } I can use .push() to add clickedElementId as a value associated to a numeric key, but then how would you remove a specific element from the array? How would you approach such a typical algo in javascript? Regards, -jj. 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! Hi Peers, I am capturing query data into different Javascript arrays and that is the only way i have for now...anyway ..i have what i want in JS arrrays > is there a war to perform CRUD operations on those arrays : my Arrays look like this : A1 : EmpID / A2 : Name / A3: Fistanme.. A1[0] : 1 / A1[0] : Paul /A1[0] : Newman A1[1] : 2 / A1[1] : Paul /A1[1] : Simon i want to be able to display the information like and give the ability to create , update or delete the record based on the EmpID unique number: EmpID / Name / Firstname 1 Paul Newman Update ( hyperlink) - Delete ( hyperlink) 2 Paul Simon Update ( hyperlink) - Delete ( hyperlink) i am using Coldfusion CF 7 and i was told since i want to keep the data into JS array that the only way to do it is usinig JAvascript any thoughts how can this be done./???

Anyone please help I am new to learning JS and am trying to create an array through a prompt. It seems to work, but I believe it is treating the prompted numbers as strings not numbers. I am parsing the negatives and zeros, and positives and counting them. It doesn't recognize the negative sign. Here's my js: function counter() { var numArr = new Array(Number(prompt("Please enter and array of numbers, in any order, separated by a comma..." + '\n' + "In the following format: -2,0,2"))); var positives = 0; var negatives = 0; var zeros = 0; for (var i = 0; i < numArr.length; i++) { switch (true) { case numArr[i] < 0: negatives++; break; case numArr[i] == 0: zeros++; break; case numArr[i] > 0: positives++; break; } } alert("You entered:"+ '\n' + "Number of Negatives: " + negatives + '\n' + "Number of Zeros: " + zeros + '\n' + "Number of Positives: " + positives); } counter(); Any suggestions? |
