JavaScript - Javascript Array Question??
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./??? Thanks Similar TutorialsHey guys, I've got a question about this array in my code. I have my array at a size of 20 and all of the elements are initialized to 5. What i want to do is when the user types in the word "dog" i want to increase one of the first 10 elements in my array by 1, increasing it from 5 to 6. How would you do such a thing?
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. 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, 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
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);

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 I want to create a script that reads the text in an anchor <a> tag, and if the parent node is a td tag, I want to sort the text in the <a> tag alphabetically. Im not sure if this would require an array or not... but one important point is the text being read would be something like Miami - Detroit or Buffalo - New York two team names separated by a hyphen. This is what I had, but again.. not sure if it needs an array in order to work, or if the '-' is important.. BUT i only want to sort by the First letter of the first team listed so Arizona - Oakland would be sorted above San Francisco - Atlanta Code:
function main(){
var a = document.getElementsByTagName('a');
for (i = 0; i < a.length; i++) {
if(a[i].parentNode.tagName == 'Td'){
var team = a[i].innerHTML;
team.sort();
}
else{
i++;
}
}
}
Please forgive my ignorance. I am definitely more designer than programmer... Not sure if this possible, If it is then I am definitely getting the syntax wrong. I'm trying to pull array data as such: var carouselC2R1Array = new Array(500, 4, 0); var currentSilo = 2; var currentImg = 1; carouselWidth = "carouselC"+currentSilo+"R"+currentImg+"Array"[0]; carouselMaxImages = "carouselC"+currentSilo+"R"+currentImg+"Array"[1]; carouselCurrentImg = "carouselC"+currentSilo+"R"+currentImg+"Array"[2]; the correct data return should be: carouselWidth = 500 carouselMaxImages = 4 carouselCurrentImg = 0 but instead, I'm getting: carouselWidth = c carouselMaxImages = a carouselCurrentImg = r Any help would be greatly appreciated! Cheers. hi, if i have an array of "hop", "skip", "jump" "run", how do i prompt the user to enter a number between 1 and 4 to bring back one of the array list without using an if or switch statement... the code i have so far is: numbers= new Array(); numbers[0]="hop"; numbers[1]="skip"; numbers[2]="jump"; numbers[3]="run"; thanks Is there a way to create new lines on a array. so if a array cald questions and theres two value questions [0] and questions [1] can i make a function that would create a questions [2]. So i am also wondering if i could do things with a array like sql? Edit: Wrong SPelling Ok...this is gonna sound very stupid to you guys, but I don't get one part of this code. Code: function range(upto) {
var result = [];
for (var i = 0; i <= upto; i++)
result[i] = i;
return result;
}
show(range(4));
What does result[i]=i mean? I know it adds the value of i into the array, but how? Why couldn't you just write it as result[i] or result[] = i? I have a bit of code that I can't decipher, beginner that I am. Code:
(function($) {
$(document).ready(function() {
$("#tmp").attr('src', loader.loadImage('test.zip://images/image.jpg'));
});
})(jQuery)
This code loads an image from a zip file and the tmp variable is passed to the id attribute in the html img tag. It works as is, but what I want to do is pass an array element containing the image name to the function from within the tag and have the function return directly rather than using the #tmp variable. The html page I'm working with has 98 images, so calling this function from within the img tag seems the way to go rather than having 98 separate instances of the function wit 98 separate tmp variables. What I don't understand is what function($) means or why tmp has the hash in front. I had assumed the hash was some sort of pointer reference but I wasn't able to find any documentation on it. Can anyone help me out? I know it's possible to do this in php, but what would the javascript equivalent be? Code: var scripts = new Array(); scripts[] = "PHP"; scripts[] = "ASP"; scripts[] = "JavaScript"; scripts[] = "HTML"; But this obviously doesn't work. And just to clarify, I mean the ability to add an array whenever I want to in my page instead of having to name the array like... Code: var scripts = new Array(); scripts[0] = "PHP"; scripts[1] = "ASP"; scripts[2] = "JavaScript"; scripts[3] = "HTML"; I'm using it for such as in a form: Code: <input type="text" name="formarray[]"> <input type="text" name="formarray[]"> Thank you in advance. The following code snippet: (this.inputArray is already defined and initialized prior to this code sequence) if(this.inputArray.length >= 0) { this.inputArray[this.inputArray.length] = new Object(); this.inputArray[this.inputArray.length].type = 'pcDisp'; this.inputArray[this.inputArray.length].data = a; } the first line in the code block should create a new array item and initialize it with the various assigments in the next lines. But Firefox complains "this.inputArray[this.inputArray.length] is not defined". This is very disconcerting because the code has to create array items with different data based on conditionals. So I must be able to automatically create new items as necessary. I thought that javascript had 'late binding', but maybe that doesn't apply here. So, does anyone have a clue for me? Hi, what would be the best way to have a hidden array of possible text directed at a textarea and then if something is not within that array "onfocus", a certain select option is chosen within that form? Thanks 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 Guys!! My name is Megan and I am a college student in need of some JavaScript help for my computer science class!! My professor is making us complete some stupid class project for finals and I can't figure it out! He suggested that we may try to find a JavaScript Website to help us if we have trouble figuring out how to write the code. I have looked and looked and can't find out how to fix my code!! We have to write code to make a slot machine .. I have started the code based on what he gave us and have tried my hardest to figure out how to complete it but I do not know how to finish it. I have the images working correctly (kind of.. the second one seems to have problems loading? I dunno what I did to mess that up) and the counter working, but I need to make it add 13 credits when all 3 images are the same. I added code that I thought would work but it's not for some reason that I can't figure out. It should also pop up an alert screen when all 3 are correct and you win. I guess this would have to be including with the if statement and something like alert('You win 12 credits!!!') Lastly I need to add code that prevents the person from playing when the credit line is 0 (so you can't get - credits!) and I have no idea how to do this. Any help would be greatly appreciated!

I'm not really looking for someone to fix/answer this for me, but maybe give me a hit in the right direction. I need to fix this while loop to run correctly, but has errors in the code. This code is supposed to fill an array with numbers 1 through 100 and then print them. Here is the code: <script type="text/javascript"> /* <![CDATA[ */ var count = 0; var numbers = new Array(100); while (count < 100) { numbers[count] = count; ++count; } while (count < 100 ) { document.write(numbers[count]); ++count; } /* ]]> */ </script> What i am most confused about is this part of the code numbers[count] i don't understand what is going on there. Sorry i am very new to this. Any ideas would be appreciated thank you. I'm trying to figure out this question that was assigned to me, as I haven't done alot on javascript before but I've tried to get most of this, I'm just not sure if this is correct. If anybody could help it would be greatly appreciated. The question is as follows: You are provided with a string array called country that contains the name of every country that the Ski Club visits. For example one element of this array might be as follows: country[0] = "Austria" Another array called villages contains strings with information on village names and altitude in a particular country. For example: villages[0] = "Austria:Seefield 850m*"; Write a JavaScript function snowReport(countryIndex) that will use the arrays provided to write a report of all villages that include a given country. The function will be passed an integer representing the index of an element of the country array. A match is found if the country appears in a string (Hint use appropriate JavaScript function to evaluate if a country name is contained in a village string.) All matching villages should be displayed. Output should be displayed in the villages div element you defined in part (a). Output is shown for a search for Austria in Figure 1b. <script type="text/javascript"> function makeArray() { var country = new Array(5); country[0] = "Austria"; country[1] = "Canada"; country[2] = "France"; country[3] = "Germany"; country[4] = "Switzerland"; return country; var villages = new Array(2); villages[0] = "Austria:Seefield 850m*"; villages[1] = "Austria:Ellam 100m"; return villages; } function snowReport(countryIndex){ var string = ""; for (var i = 0; i < countryIndex.length; i++){ str += countryIndex[i] + " "; } return str; } </script> </head> <body> <script> var x = makeArray(); document.write(snowReport(x)); </script> </body> </html> Many thanks! Hey Guys, I was creating an image map with rollover images. I was just wondering if I could add a fade effect to the transition. The underarms is the only rollover that works at the moment. Please check the source code for the code because it's too long to post here. http://wedezign.com/chris/ I have an application that has a menu - one of the choices on that menu is "Contacts" - This menu is controlled by css - I've written a script that will modify the css style setting for "display" and "zindex" for the rule that controls the pull down for contacts - this worked for hover, but I am now trying to change to a click event - I successfully change the rule, but the menu doesn't display - not sure if I'm returning incorrectly form the javascript function or what - here's a code snippet: CSS: Code: .primaryNav .subMenu {
background-color: #B0967E;
position: absolute;
width: 300px;
left: 600px; /* 823px - 300px - 20 px + 97px */
padding: 10px;
display: none;
color: #fff;
font-size: 90%;
}
Javascript: Code: <script type="text/javascript">
function SetDisplayCSS()
{
var mysheet=document.styleSheets[0];
var myrules=mysheet.cssRules? mysheet.cssRules[0].styleSheet.cssRules: mysheet.imports[0].rules;
for (i=0; i<myrules.length; i++){
if(myrules[i].selectorText.toLowerCase()==".primarynav .submenu"){ //find "a:hover" rule
targetrule=myrules[i];
alert("Rule is found");
break;
}
}

}
</script>
html Code (names have been changed to protect the innocent) - note the onclick event handler for the contacts menu option. Code: <li class="pn test"><a href="#" onclick="return SetDisplayCSS();" name="contacts">Contacts</a>
<div class="subMenu">
