JavaScript - Only Reads First Array Element
--------RESOLVED--------
I am trying to make a finance tracker, but for some reason this code will only output the first transaction: Code: <html>
<head>
<style>
tr:nth-child(even) {background: #CCC}
tr:nth-child(odd) {background: #FFF}
</style>
<script type="text/javascript">
var finance={

getDates : function (){
finance.dates=(eval("["+finance.ls.dates+"]"))
return finance.dates;
},
desc : new Array(),
getDescs : function (){
finance.desc=(eval("["+finance.ls.desc+"]"))
return finance.desc;
},
change : new Array(),
getChanges : function (){
finance.change=(eval("["+finance.ls.change+"]"))
return finance.change;
},
getAll : function(){
var t=new Array();
t[0]=finance.getCodes();
t[1]=finance.getDates();
t[2]=finance.getDescs();
t[3]=finance.getChanges();
return t;
},
getRows : function(){
var temp=new Array();
var bal=0;
for (i=0;i<finance.getAll()[0].length;i++){
bal+=finance.getAll()[3][i];
var temp3=document.createElement("tr");
var temp4=new Array();
for(a=0;a<6;a++){
temp4[a]=(document.createElement("td"))

temp4[0].innerHTML=finance.getAll()[0][i];

hahahahaha wow im dumb i forgot that nesting two for statements that use "i" is a nono also i know the code may be sloppy, i am just building it now, i will clean it up later. Similar TutorialsIm trying to add to each element within an array. In this program I have an existing array which is called aScores. I have copied its contents into another array called aScores using slice. Now Im trying to add the value of variable called classCurve to each element of aCurve using a for loop (see under the Curve Scores functrion section). However, it does not seem to add the two together(e.g 78 + 5). Any advice would be very helpful. Here is my code: Code: <?xml version="1.0" encoding="UTF-8"?>

Hi. I'm fairly new to javascript. I have a code where I'm trying to generate scrollx1 through scrollx100. I can get the array to work with doc.write and I can get one concat variable to work in the element but when I combine them it doesn't work. Any suggestions as to what I need to add to this code: var sp=1; for (sp=1;sp<=100;sp++) { var sx = "scrollx"; var sy = "scrolly"; var thissx = sx + sp; var thissy = sy + sp; theForm[thissx].value = scrollx; theForm[thissy].value = scrolly; } Any help would be much appreciated!!

}
Any help would be much appreciated!! What I need help with is sorting the [0] of my array. I need it to sort so that if the user puts in his last name, whether its uppercase or lowercase (Adams, adams), it will sort through the list of students I add, and put them in an alphabetic order i.e adams, Adams, cook, Douglas....and so on. Here is the code that I have below for just sorting by last name, which will seperate the lowercase entries from the uppercase entries. That would be the opposite of what I want. I had it sorted so that it would sort the [o], which is where the last name value is located. Any thoughtful help would be appreciated. Code: function Last_names( s1, s2 )
{
if ( s1[0] > s2[0] ) return 1;
return 0;
}
function sortLast(form)
{
StudentsLists.sort( Last_names );
windows(form);//calling the windows function each time the sortLast function is called
}
Hi, Below is the code which is used to validate the entries on a form(some field are not be left blank). The user gets the msg when he hits the "Check"button. The problem is after the user gets the msg, I am not able to set the focus in the field which is the first element of an error array which stores the info about the fields with errors on this form. Please help. ========================================================== <html> <head> <script type="text/javascript"> function check_alert() { var errors=[]; if (text1.value==""||text1.value==null) { errors[errors.length]="Please enter the Company Name"; } if(text3.value==""||text3.value==null) { errors[errors.length]="Please enter the Address"; } if(text5.value==""||text5.value==null) { errors[errors.length]="Please enter the City"; } if(text6.value==""||text6.value==null) { errors[errors.length]="Please enter the Zip/Costal Code"; } if(text7.value==""||text7.value==null) { errors[errors.length]="Please enter the Country"; } if (errors.length>0) { reportErrors(errors); return false; } else return true; } function reportErrors(errors) { var msg="There are some errors..\n"; var numerror; for (var i=0;i<errors.length;i++) { numerror=i+1; msg+="\n"+numerror+"."+errors[i]; } alert(msg); document.form.element(errors[0]).focus(); } </script> </head> <body onload="text1.focus()"> Company:<input type="text" name="text1" /><br> Division:<input type="text" name="text2" /><br> Address1:<input type="text" name="text3" /><br> Address2:<input type="text" name="text4" /><br> City:<input type="text" name="text5" /><br> State:<select name="state"> <option value= "Alabama" selected>Alabama</option> <option value= "Alaska">Alaska</option> <option value= "Arizona">Arizona</option> <option value= "Arkansas">Arkansas</option> </select><br> Zip/Postal Code:<input type="text" name="text6"/><br> Country:<input type="text" name="text7" /><br> <input type="button" value="Check" onclick="return check_alert()"/> </body> </html> ======================================================= I want to create an array for a religious website that will display a different Bible verse for each day of the year. This is how I incremented each day of the year. Code: var myDate=new Date(); myDate.setFullYear(2011,2,4); myDate.setDate(myDate.getDate()+1); How do I make the connection between the array and the new date as it changes? This is a snippet from the array. Code: var dailyVerseRef=new Array(); dailyVerseRef[0]="Genesis 1:1"; dailyVerseRef[2]="Genesis 1:2"; dailyVerseRef[3]="Genesis 1:3"; dailyVerseRef[4]="Genesis 1:4"; dailyVerseRef[5]="Genesis 1:5"; dailyVerseRef[6]="Genesis 1:6"; dailyVerseRef[7]="Genesis 1:7"; dailyVerseRef[8]="Genesis 1:8"; I used a switch to go through the days of the week, but to go through the days of the year seems more difficult. Hi all. I am having a problem understanding exactly how setInterval and setTimeout work and really need some help. I want to create an array and then print out each element one at a time at one second intervals. I've only been able to come up with something like this, but it just prints the last value of the array after a second. Code:
<script type = "text/javascript">
<!--
var myArray = new Array();
for (var i = 0; i < 11; i++){
myArray[i]=i+50;
}
for (var i = 0; i < myArray.length-1; i++){
setInterval("document.getElementById('here').innerHTML = myArray[i];", 1000);
}
//-->
</script>
<div id="here">Stuff here</div>
I'm hoping someone can help correct a small problem with this script, which is intended to highlight particular text strings. Background: The script is being used at a MediaWiki site, and is adapted from a working script from Wikipedia (highlightmyname.js). The original script highlights the logged-in user's username (represented by wgUserName). I've made a copy of the script, which you can see in full here, and adapted it to work on a pre-defined array of names, adding: Code: var Admin; var ArrayAdmins = ['Adam', 'Axiomist', 'Matt', 'Steve']; for (Admin in ArrayAdmins) I also replaced each instance of wgUserName with ArrayAdmins[Admin] The problem: is that, instead of highlighting all instances of every element in ArrayAdmins, only the last element listed ('Steve') is being used. So my question is, what change(s) need to be made to apply function highlightmyname to every element in ArrayAdmins? Any help would be hugely appreciated!

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init()
{
// Grab the appropriate div
theDiv = document.getElementById('scrollbox');
// Grab all of the links inside the div
links = theDiv.getElementsByTagName('a');
// Loop through those links and attach the target attribute
for (var i=0, len=links.length; i < len; i++) {
// the _blank will make the link open in new window
links[i].setAttribute('target', '_blank');
}
}
window.onload = Init;
But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! Hi, (new to javascript) Code: digAudio = document.createElement("audio");
digAudio.setAttribute('src',hypeDocument.documentName()+'_Resources/'+'digging.m4a');
digAudio.id = "diggingAudio";
newAudio = document.getElementById("diggingAudio"); //returns null
the audio element is added (I can play the audio) but I can't get it by its id ? thank you I have the following code Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a></td> </div> what i want to do is this: Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a><a href="anotherlink">another_link</a></td> </div> how can i go about achieving this? 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. Alright, this is going to sound strange, but bear with me here... Code: <input type="text" name="_F0827U" size="015" maxlength="015"> <input type="submit" class="cmdkey" name="_K040827" value="..."> Say I have multiple isntances that look similar to the above. However, I have no possible way of identifying them uniquely (because I don't know the name prior to generation). Is it posable, using JS, to snag the previous element and strip it of it's tags then rewrite a new element isntead of the two originals, say using an onClick() event on either of the elements? So, I have this javascript that works just fine... But... PHP Code: <script language="javascript"> function addBtn() { element = document.createElement("input"); element.setAttribute("type", 'button'); element.setAttribute("value", 'Track'); element.setAttribute("name", 'element'); element.onclick = function() { alert("Tracking"); }; var btn = document.getElementById("gs-track-btn"); btn.appendChild(element); } </script> <div id="gs-track-btn"></div> How would I target that div if the " gs-track-btn " id was a class? Alright, I need a little help with my javascript. I'm a bit of a novice when it comes to programming so I apologize if this appears trivial. I have an element ID that begins with bb + a randomized number between 1-100,000. This number changes after every action so what I need is a way to retrieve this new value each time and implement it into my code. I can view the number using firebug but I need a way to automate this process. Do any of you have some advice about how I could approach this problem? Ok, Simpler question. I'm trying to get the text in an xml element. Instead of getting just the text in the first child element I'm getting the text of all the children elements. How can I get it from just the first? Code: var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
function xmlload(filexml)
{
xmlDoc.async="false";
xmlDoc.load(filexml);
xmlObj=xmlDoc.documentElement;
}
xmlload('urlhere');
document.getElementById("nmbr").value=myVar;
myVar = xmlObj.childNodes(0).childNodes(19).firstChild.text;
document.getElementById("comment_t").innerText= myVar;
HI I want to write a search for my site .I make a new panel in the left of my menue and it has a text input and an image which when that user click on it javascript opens a new window which is a php page.The part I don't know how to do is when the user click on the image it should get the content of the text input and pass it to the url.For the hyperlink of the image I use "<a href="javascriptpen_window('includes/func/search.php?id=" But I don't know what should I write after that to get the content of the text input and put it in the next of the id. How can I do so? Thanks Hello I am fairly new to Javascript and found this code online but can't seem to get it to work right. here is the code I am using it is suppose to apply a style attribute the the id "toplink" but I can't seem to get it to work right. Code: $(document).ready(function(){
menuYloc = parseInt($(name).css("top").substring(0,$(name).css("top").indexOf("px")))
$(window).scroll(function () {
var offset = menuYloc+$(document).scrollTop()+"px";
$("#toplink").animate({top:offset},{duration:500,queue:false});
});
});
Thanks in advance greetings everyone! this is my first time trying to join this javascript community. Well then, now I'm telling about my miss-understanding of this keywords of javascript here... here's the html Code: <fieldset > <legend>Attachment</legend>
<table id="attachment" style="height: 50px;" width="200" border="0">
<th width="19%">Title</th>
<th width="26%">File</th>
<th width="41%">Description</th>
<th width="6%">Upload</th>
<th width="6%">More File</th>
<tr>
<td><input name="title" type="text" value="- none -" size="33" maxlength="50"></td>
<td><input name="filepath" type="file" size="33"></td>
<td><input name="description" type="text" value="- none -" size="60" maxlength="200"></td>
<td><input name="upload" type="button" value=" Upload " onclick="upload(this)"> </td>
<td><div align="center">
<input onclick="addMoreFile()" type="button" value="+">
</div></td>
</tr>
</table>
<!-- end Attachment --> </fieldset>
the aim is that the upload button would eventually changed into image and then changed back to a link. That one is already done here's the javascript Code: var attRow;
function upload(obj){
// obtain the table pointer
var attTable = document.getElementById('attachment');
// post file into the jsp file
// changing the image
// get parent pointer of this element
var par = obj.parentNode;
var loImage = document.createElement('img');
loImage.setAttribute('src', 'images/loading1.gif');

var nFileTitle = document.createElement('input');
nFileTitle.setAttribute('name','title');
nFileTitle.setAttribute('type','text');

var nDesc = document.createElement('input');

var nUpButton = document.createElement('input');
nUpButton.setAttribute('name', 'upload');
nUpButton.setAttribute('type', 'button');
nUpButton.setAttribute('value', ' Upload ');
nUpButton.setAttribute('onclick', 'upload(this)');
// empty element
var ksg = document.createTextNode(' ');
// obtain the table pointer
var attTable = document.getElementById('attachment');
attRow = attTable.rows.length;
alert(attRow);
var nextRow = attTable.insertRow(attRow);
var ceL = nextRow.insertCell(0);
ceL.appendChild(nFileTitle);
ceL = nextRow.insertCell(1);
ceL.appendChild(nFilePath);
ceL = nextRow.insertCell(2);
ceL.appendChild(nDesc);
ceL = nextRow.insertCell(3);
ceL.appendChild(nUpButton);
ceL = nextRow.insertCell(4);
ceL.appendChild(ksg);
}
the problem arise when I try to use the removeFile() function using this keywords. into these; Code: function removeFile(obj){
// post fileid
// change the image back
// get parent pointer of this element
var par = obj.parentNode;
var loImage = document.createElement('img');
loImage.setAttribute('src', 'images/loading1.gif');
}
I try to apply the same approach as the upload() function. But instead the this object which is pointing at the parent node seems unreliable. Is there any missing point i haven't observed? |
