JavaScript - Need A More Efficient Way To Add Input Fields
So I made myself this code so I could have a file upload input field, and the option to add more fields. but it got really big, and I have a fixed number of fields, can't quickly change the number I want.
here's my javascript: Code: function new_field(id) {
var f = document.getElementById(id);
if(f.style.display == 'none')
f.style.display = 'block';
}
function hide_mais(id) {
var g = document.getElementById(id);
g.style.display = 'none';
}
and the html: Code: <form>
<div id="file_a" style="display:block"><input type="file" /><a href="#" id="link_a" onclick="new_field('file_b');hide_mais('link_a')">mais</a></div>
<div id="file_b" style="display:none"><input type="file" /><a href="#" id="link_b" onclick="new_field('file_c');hide_mais('link_b')">mais</a></div>
<div id="file_c" style="display:none"><input type="file" /><a href="#" id="link_c" onclick="new_field('file_d');hide_mais('link_c')">mais</a></div>

</form>
any suggestions of a more efficient way to do that? also a button to reset form into initial state, with one field only, without having to refresh the page would be cool. thanks in advance Similar TutorialsHello, I would like to create a form that calculates the area of a floor or wall. The user will input the length/height and width dimensions into two input fields and then click calculate. I simply need a script that multiplies the two fields together and puts the answer in a third read-only field. Any help much appriciated Kind regards, Mike Hi, i've got a calculator/quotation script i've made. Once the calculation is complete, i want the user to click a button which will copy some of the field data to new fields for printing. This is fine and i can do easily, however i then want the user to be able to reset the form and do another calculation, click the same button and it copy the new data to new fields too. So in effect you end up with all of your calculations listed somewhere for printing. how would i attempt this? any help appreciated Hello Everyone, I am inexperienced in JavaScript. I have an html page with several numeric input fields which are an array. At the bottom of the screen is a running total of the numbers entered. The html is like: <INPUT TYPE=TEXT NAME='array[0]' onchange='addup()'> <INPUT TYPE=TEXT NAME='array[1]' onchange='addup()'> etc..... <INPUT TYPE=TEXT NAME='array[9]' onchange='addup()'> <INPUT TYPE=TEXT NAME='arraytotal'> The javascript is: function addup() { var total = 0; for (var i=0; i<=10; i++) { total += Number(document.forms["formname"]["array["+i+"]"].value); } document.forms["formname"]["arraytotal"].value = total; } This works ok, but I don't want the field arraytotal to be an input field. How can I do this please? I have a registration form that I am working on in which I need to assign a price to each option in a selection box then write that price in the document. Then I have a radio button that will add (different amounts based on selection) to that price before it is written. Then I have another radio button that just needs to write a price based on its selection. Both of these values will be written and then totaled. (See below for a less confusing explanation) On HTML form: >drop down list (name courseName, value of selections 1,2,3,4) > radio button (name returnStudent, value of selections 1,2) > radio button (name bookNeeded, value of selections 1,2) Table (name totalprice) at the bottom of the form: price1: price of courseName plus returnStudent (td with name tuitionprice) price2: price of bookNeeded (td with name bookprice) Total of the above (td with name totalprice) This is what I am trying to make work... Code: var selectedCourse = document.onsiteRegistration.courseName.value;
var selectedStudent = document.onsiteRegistration.returnStudent.value;
function setTuition()
{
if (selectedCourse == "1" && selectedStudent =="1")
{
document.write("12345");
}
if (selectedCourse == "1" && selectedStudent =="2")
{
document.write("54321");
}
}
Then in my HTML I have simply put this to call the function and write it where I need it to be placed. <script>setTuition()</script> I am trying to find some examples of something like this but all I am coming up with is shopping carts and that is not what I need here. I am fairly confident that I can program the second part (totaling) if I can only get the selections to populate the different prices for me. If someone could point me in the right direction I would be very grateful! Hi to all, I have a dynamic form, when a button is clicked 3 more fields appear, the function is to colect for example from date [02/02/2010] to date [10/02/2010] equals price [250$] per week and if you want another period just click the button and 3 more fields appear. How do I get all this data to PHP? Code: <script type="text/javascript">
var counter = 3;
function addNew() {
// Get the main Div in which all the other divs will be added
var mainContainer = document.getElementById('mainContainer');
// Create a new div for holding text and button input elements
var newDiv = document.createElement('div');
// Create a new text input
var newText = document.createElement('input');
newText.type = "text";
newText.value = "DD/MM/AAAA";
newText.name = counter++;
var newText1 = document.createElement('input');
newText1.type = "text";
newText1.value = "DD/MM/AAAA";
newText1.name = counter++;
var newText2 = document.createElement('input');
newText2.type = "text";
newText2.value = "0";
newText2.name = counter++;
// Create a new button input
var newDelButton = document.createElement('input');
newDelButton.type = "button";
newDelButton.value = "Delete";
// Append new text input to the newDiv
newDiv.appendChild(newText);
newDiv.appendChild(newText1);
newDiv.appendChild(newText2);
// Append new button input to the newDiv
newDiv.appendChild(newDelButton);
// Append newDiv input to the mainContainer div
mainContainer.appendChild(newDiv);
counter++;
// Add a handler to button for deleting the newDiv from the mainContainer
newDelButton.onclick = function() {
mainContainer.removeChild(newDiv);
}
}

Hi Within a classic asp webform (using vbscript) I would like part of the form (input boxes within table structure) to be specific/displayed depending on the users selection from the combo box in the row above. I think the best solution would be using Javascript can anyone suggest a solution or example code? Many thanks Sarah The simplified code below works, and should give you an idea of what Im trying to achieve. The final version will have dozens of input fields so you can see why the below method stinks Code: <html><head><title>Values</title>
<script type="text/javascript">
<!--
function getid() {
var myNum = document.frm1.field1.value;
if(myNum == "A"){
document.frm1.field2.value = "1"
} else if(myNum == "B"){
document.frm1.field2.value = "2"
} else {
document.frm1.field2.value = ""
}
var myNum2 = document.frm1.field3.value;
if(myNum2 == "A"){
document.frm1.field4.value = "1"
} else if(myNum2 == "B"){
document.frm1.field4.value = "2"
} else {
document.frm1.field4.value = ""
}
}
//-->
</script>
</head><body>
<form name="frm1" id="frm1">
<input type="text" size="40" name="field1" id="field1" onChange="JavaScript:getid();" /><input type="text" size="4" id="field2" name="field2" /> <br>
<input type="text" size="40" name="field3" id="field3" onChange="JavaScript:getid();" /><input type="text" size="4" id="field4" name="field4" /> <br>
</form>
</body>
</html>
Each text input will have A or B written in by the user, which should automatically place that letters associated ID in its partner field. If any other letter is entered the ID will automatically be left blank. With the above code I'd need to repeat it over and over for each of the dozens of input fields. The final version wont be using simply A/B either but around 50 possible inputs each with their own ID which would make around 1000 possible variations. What am I missing here that will simplify the process? Thanks Right.. I'm still new to javascript so i've just been messing about with some code and came up with a pointless small program i just wanted to know if the code written is efficient? in other words are there other ways that would be more suitable or are certain parts of the code wrong? The script basically does this. 1. prompts you to enter a time interval in the range of 1 second to 10 seconds 2. A small box appears with a random number generated at the time interval the user entered. IF you enter a number lower or higher then in that range it prompts you again to enter a valid number. If you click cancel you automatically get a time interval of 1 second Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

Right now I am using the following method to show/hide divs containing videos. html Code: <div class="vidPop" id="vidPop">
<div class="vidFrame" id="vidFrame">

<div class="vidClose"><a href="#" onclick="vidPopdown()"><img src="images/closeban.png" width="52" height="52" alt="close" /></a></div>
</div>
</div>
<div class="vidPop2" id="vidPop2">

<div class="vidClose"><a href="#" onclick="vidPopdown2()"><img src="images/closeban.png" width="52" height="52" alt="close" /></a></div>
</div>
</div>
js Code: function vidPopup() {
var o = document.getElementById('vidPop');
o.style.visibility = 'visible';
o = document.getElementById('vidFrame');
o.style.visibility = 'visible';
}
function vidPopdown() {
var o = document.getElementById('vidPop');
o.style.visibility = 'hidden';
o = document.getElementById('vidFrame');
o.style.visibility = 'hidden';
document.getElementById('Iframe1').src = document.getElementById('Iframe1').src
}
function vidPopup2() {
var o = document.getElementById('vidPop2');
o.style.visibility = 'visible';
o = document.getElementById('vidFrame2');
o.style.visibility = 'visible';
}
function vidPopdown2() {
var o = document.getElementById('vidPop2');
o.style.visibility = 'hidden';
o = document.getElementById('vidFrame2');
o.style.visibility = 'hidden';
document.getElementById('Iframe2').src = document.getElementById('Iframe2').src
}
all of this works just fine, but now I am adding yet another video, and I know that this isn't the best way to go about doing this. I ought to be able to use 1 function and tell it which iframe to load, however I dont really know javascript. Any and all help on this would be greatly appreciated. I type something on the current textarea/input and all the values get removed after I add another field. Is there a solution? Code: <script language="Javascript" type="text/javascript">
<!--

//Find the count of the last element of the list. It will be in the format '<field><number>'. If the

The page loads and existing data is put in their correct fields. When I click 'add more' to add more fields to the form it does so and I am able to add new data. If on adding a new fields and its data I click 'add more' again it clears out the recently added data from the fields. The existing data that was present when the page first loaded is still their but all the new fields added data is cleared. how can I get it so the data stays, like in phpmyadmin when adding new fields. JS Code: function addmore(addwhat) {
// count existing boxes to find out next number to use.
// ?
if (addwhat == 'addresses') {
fieldid = 'addressesdiv';
}
if (addwhat == 'namesnumbers') {
fieldid = 'namesdiv';
}
var dv = document.getElementById(fieldid).innerHTML;
var lines = dv.match(/<br>/ig).length;
if (addwhat == 'addresses') {
document.getElementById('addressesdiv').innerHTML += '<textarea name="address' + lines + '" cols="30" rows="2"></textarea><br>';
}
if (addwhat == 'namesnumbers') {

What is the most efficient type of chat to make? From what I see online most people use a database and limit the number of results they return, but I noticed that some chats, like google and facebook, for some reason are able to load the full chat and get results almost instantly. How do they do it? I would love to make a replica of a google chat and just redesign the way it looks. If anyone can help me with the javascript/php part of this, that would be great. thanks! Hi all, I've been trying to build a form with dynamic checkboxes. I'd like to have a master 'select none' checkbox in a few form fields which has 2 key functions:- 1) clearing all field boxes the user may have entered before opting to select none 2) disabling all field options to make it impossible for the user to tick both 'none' and other options. This 'select none' checkbox should be ticked by default, so when the user unchecks it, the rest of the field options light up. I'm a complete novice but I have it working ok having stitched a few pieces of code I've found together, however I don't think it's very efficient. I have had to duplicate both bits of the javascript to make it work, changing only the function names in the <head> area ('Uncheck' and 'Uncheck2') and the class variables in the form in the <body> area ('fruit_child' and 'veg_child'). As this form will have several more fields eventually, I'm looking for a better way to do this while maintaining the functionality. Ive read bits about object-orientated programming which may be what I'm looking for to make this more efficient, but I'm not sure how to implement it in this example. Can a more experienced coder please help? Kind thanks, Fleef Code: <head>

If you go to a Youtube video by Justin Bieber or Rebecca Black, comments are constantly being posted and it seems like the autorefresh for the comments kicks in every half second. I don't plan on having millions of users viewing my page, but still, wouldn't having every user make a [mysql] request to the server every half second really take a toll on the server (especially since I don't plan to ever have the resources that Youtube has)? Facebook also seems to have instantaneous auto-refreshes, be it in comment boxes or their chat interface. So what would be the best method to implement a near-instantaneous autorefresh system with minimal resource usage? I have a problem with adding new inputs to a form (if and when required), Internet Explorer is fine but in Firefox if any previous input fields are filled when the more button is clicked they get reset to blank. JS: Code: fields = 0;
function addInput() {
if (fields != 100) {
document.getElementById('input').innerHTML += "<input type='text' name='input[]' size='30' />";
fields += 1;
} else {
document.getElementById('input').innerHTML += "<br />Maximum 100 fields allowed.";
document.form.add.disabled=true;}
}
form: Code: <form action="index.php" method="post"> <div id="input"> <input type="text" name="input[]" size="30" maxlength="15" /> </div> <!-- button --> <div id="more"> <input type="button" onclick="addInput()" name="add" value="More" /> </div> <!-- // button --> <input type="submit" name="submit" value="Submit" /> </form> as usual any help is appretiated .. I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. Hi, i want to set an input value to the same value as the input selected from another input on the same form so when the user selects input 1 i want the hidden input2 to get the same value im guessing i use onsubmit because its hidden so there wont be a focus or blur this would be part of the input Code: onsubmit="(this.value = this.othervalue)" othervalue being the other input name="othervalue" is that the correct syntax 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); Hi all can someone guide me (total JS newbie) on this presumably pretty easy task? I have a "parent" page with some text inputs in it (a form). This is what I am after: -when the user clicks a link it pops open a new window via JS - "child" (this is working). -in the "child" window there are also some text inputs (another form) (done). -when the user changes the value for 'testChild_textInput_4' in the child window, then I want it to automatically set this same value, to effectively overwrite, what is currently in 'testParent_textInput_2' in the parent window. Presumably this involves an onChange event, but it is also OK with me if the needful (the text input's value in the parent window being overwritten) happens upon the child window's form submit. If anyone can show me either trick, I would be thrilled! I set up a test page to make this all easy to talk about: http://www.yellow-turtle.com/testDumpMe_parent.html Please let me know! Thanks! -John Hi all, I'm new to here and JS but I have question for you! So I have this form with inputs that are considered arrays in my PHP code: Code: <input type="checkbox" name="1" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="2" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="3" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="4" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="5" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="6" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="7" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="8" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="9" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="10" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="11" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="12" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="13" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="14" /> <input name="ii[]" type="text"> <br /> <input type="checkbox" name="15" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="16" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="17" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="18" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="19" /> <input name="i[]" type="text"> <br /> <input type="checkbox" name="20" /> <input name="i[]" type="text"> <br /> I don't want to keep adding in new spots every time a user want to add a new field. I would like them to be able to press a button that will add another one of those fields and so on. I'm not sure how this can be achieved but that's why I am turning to you! Thanks! |
