JavaScript - Adding Inputs Into An Array.
I want to make a script that will insert all text type inputs into an array. From there I want to be able to call them and edit them. Here is what I have so far and it is not working.
var phone1 = '702' var inputArray = new Array(); var inputs = document.getElementsByTagName('input'); inputs; if (input.type == 'text') { inputArray.push(inputs.id); } inputArray.reverse(); inputArray[0].value = phone1; Similar TutorialsIm trying to dynamically add more fields into my form. HTML: Code: <table id="add_episodes" class="editor" border="0" cellspacing="0" cellpadding="5">
<tr>
<td><input size="3" type="text" name="number" /></td>
<td><input type="text" name="title" /></td>
<td><input type="button" value="Add another text input" onClick="addInput('add_episodes', 'number');addInput('add_episodes', 'title');"></td>
</tr>
<tr>
<td></td>
<td></td>
<td>
<input name="entry_id" type="hidden" value="<?php echo $id; ?>">
<input class="input submit" type="submit" name="submit" value="Add <?php echo $type; ?>">
</td>
</tr>
</table>
Javascript Code: function addInput(divName, type)
{
var counter = 1;
var limit = 50;
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
var tr.document.createElement('<tr>');
if(type == 'number')
{
var newdiv = document.createElement(element);
newdiv.innerHTML = '<input size="3" type="text" name="number" />';
document.getElementById(add_input).appendChild(newdiv);
}
if(type == 'title')
{
var newdiv = document.createElement(element);
newdiv.innerHTML = '<input type="text" name="title[]" />';
document.getElementById(divName).appendChild(newdiv);
}
counter++;
document.getElementById(add_input).appendChild(tr);
}
}
This is one of my first times working with javascript, usually i work with PHP. Im trying to add more input elements of Code: <tr> <td><input size="3" type="text" name="number" /></td> <td><input type="text" name="title" /></td> </tr> And don't reply that i should make the names into arrays for me to submit more stuff, I'll change that later. But for simplicity and a straightforward problem. I can't get it add more form elements in the correct place or nothing happens at all. I know you can add data to array wiht the push() method but can you add a whole new line as in a = new Array a [1] [1,2,3] so it would create a new line a [2] [4,5,6]; The syntax to the array i think is wrong but you get the question. Okay so im just doing a little test and this might seem like a really stupid question but i cant figure it out...all i simply want to do is take all those numbers and get the sum then display the sum in a document.write in theory i should get 10 but i dont and idk why i have tried many many things Code: var numbers = new Array(); numbers[0] = 1; numbers[1] = 2; numbers[2] = 3; numbers[3] = 4; thanks Resolution: Code: <script type="text/javascript">
function amountTotal() {
var totalDonations = 0;
for (var i = 0; i < amount.length; i++) {
totalDonations += amount[i];
}
document.write(totalDonations);
}
</script>
I have an array in a seperate.js file that I need to step through a FOR loop to grab all these values and add them together. Here is a small sample of the array's: Code: city = new Array(); state= new Array(); zip = new Array(); amount = new Array(); date = new Array() firstName[0]="Nina"; lastName[0]="Largent"; street[0]="88 Regal Lane"; city[0]="Williamsburg"; state[0]="KY"; zip[0]="40769"; amount[0]=125; date[0]="2011-09-18"; firstName[1]="Mike"; lastName[1]="Hart"; street[1]="Da404 Barrow Street"; city[1]="London"; state[1]="KY"; zip[1]="40744"; amount[1]=75; date[1]="2011-09-18"; Here is the loop step through that I have: Code: <script src="arrays.js" type="text/javascript"></script>
<script type ="text/javascript">
function amountTotal()
var totalDonations = 0
for (var i=0; i < amount.length; i++) {
}
</script>
I am stuck on how to grab each amount index and add them together to save them as the amountTotal variable. Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code. This does not seem to be working for me though. Here is what I have thus far (in short): Code: <script language="javascript">
var teamNames = new Array(3);
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";
for (i=0; i<=31; i++) {
document.write("<p>" + teamNames[i] + "<\/p>");
}
</script>
</head>
<body>
<tr><td>Jun 11</td><td><input type="checkbox"
name="teamNames[0]" value="teamAbbr[0]"></td>
</body>
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far. Any help would be great! I've got this little chunk of code running on my freelance portfolio site - on each page (different sections of my portfolio) I have 6 thumbnails and a full sized graphic with some descriptive info, you click the thumbnail and it switches the graphic and other info, that all works fine. But on one page I have some web stuff and I'd like to make the var 'clientinfo' into a link to go to the client's website. I know I need to add an array with the website links, but then I'm not sure how to implement it into the html, I've tried various things I've found on here but I'm not getting anywhere on my own. I know it's something pretty simple (for someone who knows what they're doing) but I just can't seem to grasp it. Can anyone help? the js is like this: $(function() { $(".image").click(function() { var image = $(this).attr("rel"); var title = $(this).attr("title"); var description = $(this).attr("content"); var clientinfo = $(this).attr("clientinfo"); $('#gallery').hide(); $('#gallery').fadeIn('slow'); $('#image').html('<img src="' + image + '"/>'); $('#title').html(title); $('#description').html(description); $('#client').html(clientinfo); return false; }); and then the HTML anchors are like this: <a href="#" rel="images/gallery/web/site1.png" title="Site One" content="This is the descriptive info for site number one" clientinfo="Site One link" class="image"><img src="images/gallery/web/t_site1thumb.png" class="thumb" border="0"/></a> Hi all, I have a div element (i.e. <div id="main">) that contains a number of links, each with white background colors and its top and left style properties set to different values. I need to do several things with the anchors when they are clicked: When a white anchor is clicked, its background color is turned yellow and its coordinates (top and left style property values) are added to an array. The coordinates for a single anchor is to be separated by a hyphen; coordinates for multiple anchors are to be separated by a comma (eg. "0-9,0-18") When a yellow anchor is clicked, its background color is turned white and its coordinates are removed from the array. The values in the array are to be the value for a hidden input element, all separated by commas. I'm a Javascript novice and don't know where to begin. Can someone help me with this? Thanks in advance, Dude-Dastic Hi I am making a PC customization website, And I need help wit hthe inputs where you select the parts for the PC. Anyway, I need help for self updating inputs, Like if a user was to select a socket 775 processor, The form would automatically update the motherboard field from --Select a processor-- to a list of socket 775 motherboards. I am quite new at javascript I have never attempted to do anything like this myself, Although I don't know if this would need some PHP in here as well Anyway thanks in advance, Gergy Hi Folks I am trying to write a js that validates a form with two text inputs. The two inputs a 'D_techA' and 'D_techB'. I just want to add up (sum) the two input fields (which must be positive numbers) and make sure that they add up to exactly 100 (not more and not less). If they do not add up to 100, then an alert should pop up that says "The two values must add up to exactly 100." I have tried and tried to write a js that does this validation (looking at numerous validation scripts posted in this forum and elsewhere) and I just cannot seem to make it work. I would very much appreciate any suggestions! Thanks! The html code for my very simple form is: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="post" action=""> <label>Investment in Tech A <input name="D_techA" type="text" id="D_techA" /> </label> <label>Investment in Tech B <input name="D_techB" type="text" id="D_techB" /> </label> <p> <input name="Submit" type="submit"/> </p> </form> </body> </html> Is there a way to call everything from one element's onKeyUp (or onBlur, etc.) in another element's onKeyUp, etc? For example, I have something like this: <input type="text" name="val_1" onBlur="sum(['val_2','val_3'],'val_1');"> I would like to be able to do something like this: <input type="text" name="val_4" onBlur=" document.getElementById('val_1').onBlur; percentage('val_2','val_3','val_4');"> But that doesn't seem to work. Is there a way to do this? Thank you! Figured it out. Thanks
Hello everyone! Hi, I am a complete beginner at Javascript(started a few days ago) and was having trouble with some functions. I'm trying to get the inputs required to change based on an option selected in a drop down menu. I was intending to run different scripts based on whatever is chosen but when I ran a test using an alert function, I realized my code isn't working. I went online and found really confusing stuff like "running a for loop through an array to make a dynamic select feature". Still confused any help would be appreciated. My code thus far: Code: <html>
<head>
<title>Practice</title>
<script language="javascript">
function myScript()
{
var loanType = document.form1.loan.options.text
if (loanType == "Bank A")
{
alert("Working")
}
}
</script>
</head>
<body>
<form name="form1">
<select id="loan" name="loan" onchange="myScript">
<option></option>
<option>Bank A</option>
<Option>Bank B</Option>
</select>
</form>
</body>
</html>

I'm having an issue adding focus() to an input that is dynamically created with jquery. I'm still learning, so I've mixed in traditional js with my jquery code because it's easier for me to understand. Anyhow document.getElementById(name).style.backgroundColor="#72A4D2"; successfully changed the background of the input ID, but document.getElementById(name).focus(); does nothing. I know that this is the correct code because if I hard code an input into the form (which you can see I've commented out below, such as document.getElementById('password').focus(); it refocuses successfully on that input. Thus I'm stumped yet again. Anyone know how to deal with this issue? JS: Code:
$(function() {
var i = $('input').size() + 1;
$('a.add').click(function() {
$('<p>Username ' + i + ': <input type="text" id="user' + i + '" name="user' + i + '" onblur="javascript:checkl(this.name, this.value);"></p>').animate({ opacity: "show" }, "slow").appendTo('#inputs');
i++;
});
});
function checkl(name, value){
var errors=new Array();
var x;
var msg = "There were some problems...\n";
if (value==="") {
errors['blank'] = "Field must not be blank";
}
for (x in errors)
{
msg += "\n"+errors[x];
}
if (!(x==undefined)){
alert(msg);
document.getElementById(name).style.backgroundColor="#72A4D2"; //works, changed input background successfully
document.getElementById(name).focus(); // does NOT work, no focus
// document.getElementById('password').focus(); // successfully refocuses on hard coded 'password' input
}else{
document.getElementById(name).style.backgroundColor="";
}
}
HTML: Code: <a href="#" class="add" id="1"><img src="add.png" width="24" height="24" alt="add" title="add input" /></a> <form id="target" name="target" action="post.php" method="post" onsubmit="return validate(this);"> <div id="inputs"> <!-- dynamically created inputs here --> </div> <!-- Password: <input type="password" id="password" name="password" size="10"> --> <input type="submit" value="Send"> </form> Tearing my hair out here. I've got a table where I'm trying to append additional input and file fields when someone clicks a link. The appending works fine, but when I click submit, none of the appended values are being passed through. I've tried it two different ways (both being appended to the "moreSwatches" table cell: Code: function addSwatch2()
{
var moreSwatches = document.getElementById('moreSwatches');
imgBox = document.createElement("input");
//imgBox.type = 'file';
//imgBox.name = 'swatch[]';
imgBox.setAttribute("type","file");
imgBox.setAttribute("name","swatch[]");
moreSwatches.appendChild(imgBox);
textBox = document.createElement("input");
textBox.type = 'text';
textBox.name = 'swatchname[]';
moreSwatches.appendChild(textBox);
setBR = document.createElement("br");
moreSwatches.appendChild(setBR);
}
function addSwatch()
{
var moreSwatches = document.getElementById('moreSwatches');
var newDiv = document.createElement("div");
addText = '<input type="file" name="swatch[]" style="width: 300px"> <input name="swatchname[]" size="25"><br>';
newDiv.innerHTML = addText;
moreSwatches.appendChild(newDiv);
}
If I hardcode a second set of inputs below the first, it works fine. Anything that is appended is getting ignored. Anyone got any ideas?

Maybe not the best way, but it does the trick. Reply With Quote 01-08-2015, 11:43 AM #3 Philip M View Profile View Forum Posts Supreme Master coder! Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts You have quite a lot of obsolete code:- 1) It is obsolete to assign a name to a form and permitted only for the sake of backwards compatibility. 2) <script language=javascript> is long deprecated and obsolete. Use <script type = "text/javascript"> instead (in fact also deprecated but still necessary for IE<9). 3) Scripts should normally be placed right in front of the </body> tag. Any script can optionally go in the head if you wrap it inside a load event listener so that it can't run before the page loads. 4) Use the value of a select box option, not the text. 5) It is recommended that you place the opening brace following the function, if, else, for, while, do, switch, and try statements on the same line and not on the following line. Apart from that every Javascript statement should be followed by a semi-colon (;). It is quite possible to disregard this advice, but if you do one day it will rise up and bite you in the undercarriage. Code: <html>

The Warrington players can hang their heads high. - Commentator, BBC Radio 2 I need to style a checkbox, so I made it into two images behind a form with hidden inputs. On click the form takes input from the other form into the hidden fields and POSTs it. Then I use PHP to grab that POST and put it back into the original form. Here are some snippets of what I am trying to do: First form input: PHP Code: <input type="text" name="email" id="email1" value="<?php if(isset($_POST['email2'])) { echo $_POST['email2']; } ?>" style="height:25px;width:270px;" /> Second form input: PHP Code: <input type="hidden" name="email2" id="email2" /> Second form submit image button: PHP Code: <input type="image" src="img/Boxchecked.jpg" value="submit" onclick="fname2.value = fname1.value; lname2.value = lname1.value; email2.value = email1.value" width="20" height="20" /> The forms work fantastic on everything but IE, which does not save the field values. How do I fix the onclick event to save them in IE? Help is much appreciated. I have taken lots of programming classes, but am now taking my first web programming class and I am getting sooooo frustrated. I have done lots of looking on the web, but am still unable to figure out why I can not make this simple assignment work. I just need some help with getting something to happen when the user hits submit. What I really want is for a new page to appear with the message using the user inputs, but I would be very happy with just getting the input to appear in the text area that I put in or even for the alert box to pop up with the input. I can work on validation code after I can get some kind of output to work..... I posted everything (due to it's small size), including my attempts to see what is working. Here is the code I have written: Code: <html>
<head>
<title>Name and Age</title>
<script type="text/javascript">
<!--
function Submit()
{
alert("Does this do anything?");
var name = document.forms['NameAge'].elements[0];
var year = document.forms['NameAge'].elements[1];
var date = new Date();
var curr_yr = date.GetFullYear();
var age = (curr_yr - year)
alert("<h3>Hello, " + name + ", you are " + age + " years old."</h3>");
document.close()
/*if (year > curr_yr)
{
alert("You must enter a valid year!");
}
else
{
document.writeln("<h3>Hello, " + name + ", you are " + age + " years old."</h3>");
document.close()
}*/
document.forms['NameAge'].output.value = "<h3>Hello, " + name + ", you are " + age + " years old."</h3>";
}
-->
</script>
</head>
<body>
<h1>Name and Age</h1>
<form name="NameAge" onsubmit="Submit()">
<p align="left">Please Enter Your Name:
<input id="name" maxlength="32" size="24" />
</p>
<p align="left">Please Enter the Year You Were Born:
<input id="year" maxlength="4" size="24" />
</p>
<input type="submit" value="Submit" /><br />
<textarea cols="10" rows="3" name="output"></textarea>
</form>
</body>
</html>
I have the two functions below, I want to write a function that puts them into a chart, I have the chart sorted etc but just struggling with how to get the actual validated users inputs from these two functions into the chart, I've tried document.write('<td> $' + productIndex + '</td>'); into the chart but that wouldn't work anyway as there could be multiple inputs? Just need a way to get the output really. function getProductChoice(min, max) { var getProductChoice = function(min, max){ do{ var productIndex = parseInt(prompt('Enter your product choice; 0-5', '0')); } while( isNaN(productIndex) || productIndex < min || productIndex > max); }; getProductChoice(0,5); } function getProductQuantity(max) { do{ var productIndexQuantity = parseInt(prompt('How many would you like?', '0')); } while( isNaN(productIndexQuantity) || productIndexQuantity < 0 || productIndexQuantity > max); }; getProductQuantity(MAX_QUANTITY); |
