JavaScript - Dynamic Array Name In Functions?
Hi all,
I am a relatively new to javacript and need some help. I have several arrays already defined: array_1 array_2 array_3 etc. I also have a few divs with ids and classes: <div id="1" class="sample"></div> <div id="2" class="sample"></div> <div id="3" class="sample"></div> etc. I am trying to use the class (sample) to run a function: (1) first I get the ID: current_id = $(this).attr("id"); (2) based on the id I want to display the array: alert('array_'+current_id); The problem is I get an alert box with the array name ("array_1") and not the CONTENT of the array. How do i solve this? Thanks!! Similar TutorialsHi, I have the following code: Code: function addHandlers()
{
var elementList = new Array();
elementList.push(new Element("newhomesdiv", "images/newhomes.png", "images/newhomes-over.png"));
elementList.push(new Element("additionsdiv", "images/additions.png", "images/additions-over.png"));
elementList.push(new Element("homeimprovdiv", "images/homeimprove.png", "images/homeimprove-over.png"));
elementList.push(new Element("aboutusdiv", "images/aboutus1.png", "images/aboutus-over1.png"));
for(var i = 0; i < elementList.length; i++)
{
var curNode = document.getElementById(elementList[i].parentId).firstChild;
var item = elementList[i];
if(curNode)
{
/*if(curNode.addEventListener)
{
curNode.addEventListener("mouseover", function(){makeCallback(item.parentId, item.hoverImage)}, false);
curNode.addEventListener("mouseout", function(){makeCallback(item.parentId, item.regImage)}, false);
}
else if(curNode.attchEvent)
{
curNode.attachEvent("onmouseover", function(){makeCallback(item.parentId, item.hoverImage)});
curNode.attachEvent("onmouseout", function(){makeCallback(item.parentId, item.regImage)});
}
else
{
curNode["onmouseover"] = makeCallback(item.parentId, item.hoverImage);
curNode["onmouseout"] = makeCallback(item.parentId, item.regImage);
}*/
curNode.onmouseover = makeCallback(item.parentId, item.hoverImage);
curNode.onmouseout = makeCallback(item.parentId, item.regImage);
}
}
}
function makeCallback(parId, image)
{
return function() {
changeImage(parId, image);
};
}
function changeImage(parId, image)
{
document.getElementById(parId).firstChild.src = image;
}
The curNode.onmouseover = makeCallback(item.parentId, item.hoverImage); works, but I want to use addEventListener and fallback to the other methods. I don't understand why the addEventListener and attachEvent parts doesn't work. Any ideas? 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, I've a checkbox validation script to check for at least one ckeck. Code: <script type="text/javascript">
function chkChecks(){
isChecked=false
alert(document.forms["form1"]["checked[]"].length);
for(var i=0;i<document.forms["form1"]["checked[]"].length;i++){
if(document.forms["form1"]["checked[]"][i].checked){
isChecked=true
}
}
if(isChecked){
document.forms["form1"].submit()
}
else{
alert('Please select a checkbox')
}
}
</script>
for the form Code: <form name="form1" action="test.php"> <input type="checkbox" name="checked[]" value="1"> <input type="checkbox" name="checked[]" value="2"> <input type="checkbox" name="checked[]" value="3"> <input class="button_140" type="button" value="Check" onclick="chkChecks()"> </form> It works well for more than one checkboxes, but these are generated dynamically by PHP and if there is only one checkbox, document.forms["form1"]["checked[]"].length returns 'undefined'. Can I modify this to work in all cases? thanks, art. Hey all! So there I was newly hired and tasked with pouring through someone else's code to see what could be modified and brought up to date. After successfully finding the errors and correcting them and fulfilling the tasks my new supervisor assigned me, he slaps me on the back and says, "Well done! Now make it dynamic!" By which he meant the chapter buttons I spent hours creating from the existing code. Here's what he wants: the old code has an array, we'll call it someArray, that is assigned its values by the instructional developer as html pages are added to the course. So for example the code might look like this, Code: var someArray = new Array(4);
someArray[0] = "video1/video1.html";
someArray[1] = "video2/video2.html";
someArray[2] = "video3/video3.html";
Now, each page has an associated chapter button. So video1/video1.html would have ch1Btn, video2/video2.html would have ch2Btn and so forth. Each button in turn calls a specific function which does only one thing - sets the currentPage variable to page associated with that button/array contents. For example, I have created the following functions to call each page: Code:
function doCh1(){currentPage = 0; goToPage();}
function doCh2(){currentPage = 1; goToPage();}
function doCh3(){currentPage = 2; goToPage();}
I should mention that all this is being done from within an html wrapper that calls each page into an iframe. The currentPage variable is assigned the url of one of the elements from the pageArray. My supervisor wants to be able to manually add pages to the pageArray and have the javascript code generate the associated buttons and function calls so when the learner clicks on one of the dynamically created buttons, s/he is taken to the correct page. Currently I'm using static images with the onclick calling the correct function to set my currentPage value and send the learner on his/her merry way. Is there a way to do all of this dynamically? If so, can you help me get my head around this by providing some examples? Sorry for the long post. Thank you, M I apologize in advance for my ignorance. I'm relatively new to javascript. I am trying to dynamically create a page based on information in a .txt. So far the code works. But only for a spacific line in the .txt. I would like it to create numbered divs and fill with approprate info from .txt for each line in .txt. Does that make sense? Any help you can provide would be greatly appriciated. Oh and I'm not worried about cross browser function this is for intra-net and all clients use Mozilla. P.S.: I will paste full code if necessary and it is explained exactly how. Is it: [ "my code goes here" ] or [code] my code goes here [code] Hi, I am stumped. I have been trying unsuccesfully for three days to figure something out, and it has brought me here. I am a noob javascripter, so please bear with me. I have created a page with an input button that refers to a function: Code:

i would like to change certain style elements of the array each time the button is clicked. I have 5 color sets i would like use for the page, so i would like the button to trigger the color change in a loop, ie when the last color group is reached, the next click returns to the original color set and it continues again. This is a demo page, not for actually publication. I am trying to teach myself javascript and this is an idea that came to me. The things i want to change are the background color of two div's and the top row of a table. My style sheet is seperate, and I will also do the same for the javascript once I can get it to work properly. Thank you in advance for any help. Hi all, I create textboxes dynamically by the following code function addElement() { var contentID = document.getElementById('content'); var newTBDiv = document.createElement('div'); newTBDiv.setAttribute('id','strText'+intTextBox); divname='strText'+intTextBox; newTBDiv.innerHTML = "Text "+intTextBox+": <input type='text' id='divid' +intTextBox name='txtbx[]'/>"; intTextBox = intTextBox + 1; contentID.appendChild(newTBDiv); } It works fine,but i want to get the values and validate it so i use the following code.. var idval=new Array(); for(var i=0;i<intTextBox;i++) { idval[i]=document.getElementById('divid').value; alert(idval[i]); } but it didn`t work out,Any suggestions really helpful. Thankyou. From the these form fields I want to be able to create an array in Javascript containing the same 'codes' that feature between the option tags (not the value="X") Code: <select name="options-1" id="options-1"> <option value="">Select an option</option> <option value="1">KA-WH</option> <option value="2">KA-BK</option> <option value="3">KA-GN</option> </select> <select name="options-2" id="options-2"> <option value="">Select an option</option> <option value="4">BADGE-1</option> <option value="5">BADGE-2</option> <option value="6">BADGE-3</option> </select> <select name="options-3" id="options-3"> <option value="">Select an option</option> <option value="7">E-WH</option> <option value="8">E-GD</option> <option value="9">E-BK</option> </select> for example, from the above, I want a JS array for 'option-1' that contains KA-WH, KA-BK and KA-GN; plus an array for 'option-2' that contains BADGE-1, BADGE-2 and BADGE-3. The above form fields will be created dynamically, may contain more or fewer items. I then want to use the JS arrays to pull in images of which filenames match the 'code' in the array. Hi, I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing. Can anyone see what I'm doing wrong? Code: function testWrapper()
{
function frequencyWrapperOne()
{
var numberArrayOne = new Array(0,0,0);
for (var i = 0; i < 1000; i = i + 1)
{
var chosenNumber = Math.floor(Math.random() * 3);
if (chosenNumber == 0)
{
numberArrayOne[0] = numberArrayOne[0] + 1;
}
if (chosenNumber == 1)
{
numberArrayOne[1] = numberArrayOne[1] + 1;
}
if (chosenNumber == 2)
{
numberArrayOne[2] = numberArrayOne[2] + 1;
}
}
return window.alert(numberArrayOne.join(','));
}
}
testWrapper();
Thanks. Ok here is what I have so far, my ending part of my Call Function I think is ok. for my main function. I think I misplaced the { and } I will show you all the codes I have for my main function this is what I have I think I did misplace something but I can not pin point where that one small things should be Code: unction showResults(race,name,party,votes)
{ // script element to display the results of a particular race
var totalV = totalVotes(votes);
document.write("<h2>" + race + "</h2>");
document.write("<table cellspacing='0'>");
document.write("<tr>");
document.write("<th>Candidate</th>");
document.write("<th class ='num'>Votes</th>");
document.write("<th class='num'>%</th>");
document.write("</tr>");
}
for (var i=0; i < name.length; i++)
{
document.write("<tr>");
document.write("<td>" name[i] + "(" + party[i] + ")</td>");
document.write("td class='num'>" + votes[i] + "</td>");
var percent=calcPercent(votes[i], totalV)
document.write("<td class='num'>(" + percent +"%)</td>");
createBar(party[i],percent)
document.write("</tr>");
}
document.write("</table>");
}
</script>
Just wondering if i misplaced any ; or { or } anywhere suggestions? Here is my call function Code: <script type="text/javascript"> showResults(race[0],name1,party1,votes1); showResults(race[1],name2,party2,votes2); showResults(race[2],name3,party3,votes3); showResults(race[3],name4,party4,votes4); showResults(race[4],name5,party5,votes5); </script> I been going over this, I can not seem to figure out what { i might be missing? Thanks Is there a way to activate a function from another function? It has to be in the script tag, it can't be in the HTML section. Can I use something similar to this following code? If not, can anyone give me some help? I have tried to do it various ways, and have looked it up a few times, but to no avail. Can I use something similar to this following code? If not, can anyone give me some help? if (condition) {activate functionname();} Any help I can get would be appreciated. Thanks a lot to anyone who can help. Hi All, i know how to create a dynamic form or DIv ..but what i do not know is how to create a dynamic form/ or div into a previous dynamic one.. i need basically to see 5 dynamic forms / DIV in cascade where each one trigger the one coming after.. For what i need that : i have my user inserting information on the level 1. let say Copagny info 2- then he will be asked if he wants to add a sub level information ( subform) for that compagny or even many subforms at the same level .. and so on... 3- those sub level ( subforms ) can also call their respective subforms.. Any idea how to design this ? thanks I have made a script where you can add extra fields, and next to the row is a span that automatically displays the outcome from a calculation of three fields in that row. i.e. Q x (B - A) = total. Here is the bit that does the calculation: Code: function advCalc(selected) {
var result = Number(document.formmain.elements["quantity"+selected].value) * (Number(document.formmain.elements["provideamount"+selected].value) - Number(document.formmain.elements["supplyamount"+selected].value)) ;
result = result.toFixed(2) ;
result = addCommas(result) ;
document.getElementById("total"+selected).innerHTML = result ;
}
The bit that adds a new row of fields is: Code: function addPart(divName){
var newdiv = document.createElement('div') ;
newdiv.setAttribute('id', 'partrow' + counter) ;
newdiv.setAttribute('style', 'clear:both;') ;
newdiv.innerHTML = "<div style='float:left;width:40px;text-align:center;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc('" + counter + "')\" id=' quantity " + counter + "' type='text' value='1' size='1'/>\r</div>\r<div style='float:left;width:100px;text-align:left;margin:5px 0px 0px 0px;'>\r<input id='manufacturer" + counter + "'type='text' value='' size='9'/>\r</div>\r<div style='float:left;width:95px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='partnumber" + counter + "'type='text' value='' size='9'/>\r</div>\r<div style='float:left;width:80px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='supplier" + counter + "'type='text' value='' size='4'/>\r</div>\r<div style='float:left;width:100px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='type" + counter + "'type='text' value='' size='6'/>\r</div>\r<div style='float:left;width:85px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='deliverytime" + counter + "'type='text' value='' size='13'/>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 0px 0px 45px;'>\r<select id='supplyCurrency" + counter + "'>\r<option value='pound' selected='selected'>£</option><option value='dol'>$</option><option value='euro'>€</option></select>\r</div>\r<div style='float:left;width:15px;text-align:left;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc(\'" + counter + "\')\" id=' supplyamount " + counter + "'type='text' value='' size='3'/>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 0px 0px 45px;'>\r<select name='provideCurrency" + counter + "'><option value='pound' selected='selected'>£</option><option value='dol'>$</option><option value='euro'>€</option></select>\r</div>\r<div style='float:left;width:15px;text-align:left;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc(\'" + counter + "\') id=' provideamount " + counter + "' type='text' value='' size='3'/>\r</div>\r<div style='float:left;width:20px;text-align:left;margin:5px 0px 0px 45px;'>\r<strong>£</strong>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 5px 0px 0px;'><span id=' total " + counter + "'></span></div> \r" ;
document.getElementById(divName).appendChild(newdiv) ;
counter++ ;
}
The problem I am having is that it works fine for the first row which is hardcoded as e.g. id="provideamount0" etc. It isn't working for any other fields added but I can't see what is wrong I would really like to thank the guys that have been helping me. I think my brain would have exploded otherwize. Some of the problems have been simple misspellings, but when you have been staring at the same thing for hours it can sorta slip by. HOPEFULLY this will be the last thing that I need some help with. Bascially Im not sure if Im using the function command properly. When Submit Details is click it should validate the form and then when Calculate is pressed calculate the form (obviously). I think maybe my var Array table is wrong? And the way the functions are set out doesnt seem it sit right. Code: <script type="text/javascript">
var element;
var itemArray = new Array();
itemArray [0] = "Bike" //not sure if these are properly writen?//
itemArray [1] = "TV"
itemArray [2] = "iPod"
itemArray [3] = "Car"
var flag="OK";
var count = 0
document.write ("<form name='myform'><br><table>");
while (count <= 3)
{
if (count < 3)
{
document.write ("<tr><td><value>Enter money from " + itemArray [count] + " sale.</td><td><input type='text' name=" + itemArray [count] + "></td></tr>");
count++
}
else
{
document.write ("<tr><td><value>Enter the price of " + itemArray [count] + ".</td><td><input type='text' name=" + itemArray [count] + "></td></tr>");
document.write ("<tr><td><input type='submit' value='Submit Details' onClick='validateform'</td></tr>");
document.write ("<tr><td><input type='submit' value='Calculate Details' onClick='calculateform'</td></tr></table></form>");
count++
}
}
function validateform() //<=== doesnt run
{
element=document.getElementsByTagName ('input');
for (counter=0; counter<element.length; counter++)
{
switch (element[counter].type)
{
case "submit":
break;
default:
if (isNaN(element[counter].value) || (element[counter].value == "") )
{
alert("You need to enter a number into " + element[counter].name);
flag="NotOK"
}
else
{
Bike=element[0].value;
TV=element[1].value;
iPod=element[2].value;
Car=element[3].value;
}
break;
}
}
}
function calculateform() //<=== Doesnt run either
{
if (flag=="OK")
{
if ( (Number(element[Bike])) && (Number(element[TV])) && (Number(element[iPod])) && (Number(element[Car])) ) //<========= Gets Bike is not defined error easy//
{
TotalMoney= parseFloat (Bike) + parseFloat (TV) + parseFloat (iPod)
if (TotalMoney >= Car)
{
alert ("The total money is " + TotalMoney + " and the car price is " + Car + " and you can afford the car")
}
else
{
alert ("The total money is " + TotalMoney + " and the car price is " + Car + " and you cannot afford the car")
}
}
}
}

This code is suppose to take the prompt number and keep subtracting one if > 1 but it seems to be not doing that at all and doing the else statement first then + till it gets to the prompt number. I have been staring at it for a while now and cant work it out. Thanks Hi, I am creating a mashUp with google maps and have a function that creates the map, marker, infowindow and all works great. I want to add more functions to that functions file. Do I start with another function Name() put my function in the {} and then I am going to use the onclick event when I want the function to run. I also am going to add more functions to this file Is that the correct way to keep adding functions? And what is the best way of calling them in my html file? Answers and examples would be great thank you . Why do we have functions without parentheses at times? Ex 1) http://www.youtube.com/watch?v=OHYFNDzlDTE (On 2:18) Ex 2) At the bottom: Code: var panel, flag;
function mousemoveResponse(e)
{
var x, y;
if( window.event )
{
x= event.x; y=event.y;
}
else if(e)
{
x=e.pageX; y=e.pageY;
}
if(flag)
{
panel.innerHTML = "Mouse is at X: " + x + ", Y: " + y ;
}
}
function mouseoverResponse()
{
flag = false;
panel.innerHTML = "Mouse is Over";
}
function mouseoutResponse()
{
flag = true ;
}
function init()
{
panel=document.getElementById("panel");
flag = true;
panel.innerHTML="Move the mouse..." ;
document.onmousemove=mousemoveResponse;
panel.onmouseover=mouseoverResponse;
panel.onmouseout=mouseoutResponse;
}
onload=init;
im no jQuery rookie but for the first time ...instead of simply writing out the animation jQuery('element').hide() in that way.... i instead needed to keep track of the functions so i wrote it like function hidetheElement() { jQuery('element').hide() } but now i need to run 2 of those functions together after a click ...for example jQuery('ClickedElement').click( movethelement,hidethelement ) see what i mean?....i dont know how to properly run two defined functions whats the proper syntax.... and here is my actual code for reference (its basically a menu link being clicked...hiding one page...and showing another....i needed to define the functions so if a menu link is clicked it could hide every other page first...by function....and then call a function to show the page Code: jQuery(document).ready( function() {
jQuery('#ladiesmenu').click(
previewoff,ladieson
);
function previewoff() {
jQuery('#preview').fadeOut(500);
}
function ladieson() {
jQuery('#ladies').fadeIn(500);
}
