Here is the script which i used
<script>
var counter = 1;
var limit = 3;
function addInput(divName) {
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
var newdiv = document.createElement('div');
newdiv.innerHTML = "Experiment Date" + (counter + 1) + " <br><input type='text' name='myInputs[]'>";
document.getElementById(divName).appendChild(newdiv);
counter++;
}
}
</script>
Here is the HTML code
<body>
<form name="form1" runat="server">
<div id="dynamicInput">
Experiment Date 1 <br/> <input id="demo2" type="text" readonly="true" name="myInputs[]" runat="server"/>
</div>
<asp:Button ID="Button8" runat="server" Text="Add more Experiments" onclientclick="addInput('dynamicInput')"/>
</form>
i also use date picker for the calendar entries, my question is that when i run the page the page is showing one entry but after click on the add more experiments the division is generated but somehow it is disappear in a second i think it is some problem of page load so what is be the solution of this and as my original form have multiple entries so can i use it there and is there is any good solution rather using this method.
Thanks for reading.
<input type="text" class="form-control" id="datepicker1" value="гггг-MM-дд" name="datepicker1"/>
<script type="text/javascript">
$('#datepicker1.form-control').datepicker(
{
dateFormat: "yy-mm-dd"});
</script>
This is with bootstrap, inside code you can use
string datepicker = Request.Form["datepicker1"];
Sorry if I don't help you.
your code is working I changed only:
<input ID="Button1" type="button" value="Dodaj" onclick="addInput('dynamicInput')"/>
And maybe in js when u add new input set id for it, to easily get data.
I hope i helped.

I need help with getElementById. My script takes the values the user typed in textboxes and when the user clicks submit the values are written to the page using document.write, however the code doesn't work as it expected.
<script type="text/javascript">
function doit() {
document.write("Do it function");
var title = document.getElementById("title1").value;
var description = document.getElementById("desc1").value;
document.write("<h3>Title: " + title + "</h3>");
document.write("<h3>Description: " + description + "</h3>");
}
</script>
The execution doesn't even reach the first line of the function. In the button I have:
<input type="submit value="submit" onclick="doit();"/>
If:
<input type="submit value="submit" onclick="doit();"/>
is indeed what you have, you're missing a quote (as should be evident by the syntax coloring, reason enough to make sure you use an editor that provides such coloring).
It should instead be:
<input type="submit" value="submit" onclick="doit();"/>
You should also be aware that document.write(), if the document has already been closed, will automatically open and clear the document, so your first write may make the controls with those IDs disappear, depending on the structure of your HTML.
Kindly change your html like this
<input type="submit" value="submit" onclick="doit();"/>
I have a forms which allows multiple steps to be submitted. When a user clicks "add step" another textarea appears. I am using CKeditor. It works great of the first iteration, but on all subsequent ones, it shows a standard text area. Here is my code:
<form method="post" action="process_project.php">
<b>Steps for your project:</b>
<div> </div>
Step 1
<div id="divWho">
<textarea name="projSteps[]" class="steps" id="1" rows="10" cols="60"></textarea>
</div>
<div> </div>
<input type="button" value="Add project step" onClick="addTextArea();">
<input type="submit" name="submit" value="submit" />
</form>
<script type="text/javascript">
var counter = 1;
var limit = 11;
function addTextArea() {
if (counter == limit-1) {
alert("You have reached the limit of adding " + counter + " project steps");
return false;
}
else {
var newdiv = document.createElement('div');
newdiv.innerHTML = "Step " + (counter + 1) + " <br><textarea name='projSteps[]' id=counter rows='10' cols='60'>";
document.getElementById('divWho').appendChild(newdiv);
counter++
return true;
}
}
</script>
<script> CKEDITOR.replace('1');</script>
How can I make each new dynamically created text areas also use CKeditor? I have been working on this for hours and I am stumped.
I think you need to move CKEDITOR.replace('1'); inside the addTextArea() method enclosed in the else block before the return statement.
And also if you hard code the replace parameter to '1', it will only convert the first instance of textarea with id 1 to CKEditor and ignore others. Generate an Id dynamically and pass it to repalce method. Something like below,
var step = 'step'+counter;
div = <textarea name='projSteps[]' id=step rows='10' cols='60'>;
CKEDITOR.replace(step);
I haven't written the second step completely, I guess you can modify it as you need.
I'm working on a similar functionality and this approach works for me.
use like this.
<textarea class="ckeditor" name="abc1"</textarea>
and in JS add this
CKEDITOR.replaceAll( 'ckeditor' );
I hope it will work for all the textareas.
So I am relatively new to JavaScript but I have experience with programming. I have this code which allows the user to define how many addresses they would like to enter so then I can query google maps and find the geographic center. The problem with this is that it looks very unprofessional in the sense that they have to enter the number of fields on one page and then they are prompted with that many boxes on the next page. Is there any way to make only one form(with all the parameters I require for one entry) and then after they click submit, I append it to an array and then when they decide they have enough addresses they hit the final submit so then I can process the data using a PHP call? Any help would be great, but I am new to this so I might need more spelt out explanations, sorry. Thanks again!
TL;DR: I want to create a single entry field which when submit is clicked, the page does not refresh or redirect to a new page and appends the data entry to an array. From there the user can enter a new input and this input would also be appended to the array until the user has decided no more inputs are necessary at which point they would click the final submit allowing me to process the data.
Here is the code I have so far:
<!DOCTYPE html>
<html class="no-js" lang="en">
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
$(function(){
var c = 0;
$("#button1").click(function(){
c = $("#inputs").val();
$("#mydiv").html("");
for(i=0;i<c;i++){
$("#mydiv").append('<input type="text" id="data'+i+'" name="data'+i+'" /><br/>');
}
});
$("#button2").click(function(){
$.post("getdata.php",$("#form1").serialize(),function(data){
});
});
});
</script>
</head>
<body>
<form id="form1">
Type the number of inputs:
<input type="text" id="inputs" name="inputs" />
<input type="button" id="button1" value="Create" />
<div id="mydiv"></div>
<input type="button" id ="button2" value="Send" />
</form>
</body>
</html>
getdata.php
<?php
for( $i=0; $i<$_POST["inputs"] ; $i++){
echo $_POST["data".$i]."\n";
}
?>
Here is code:
EDIT: I rewrite the code, so you can also delete each address
$(document).ready(function(){
$("#add-address").click(function(e){
e.preventDefault();
var numberOfAddresses = $("#form1").find("input[name^='data[address]']").length;
var label = '<label for="data[address][' + numberOfAddresses + ']">Address ' + (numberOfAddresses + 1) + '</label> ';
var input = '<input type="text" name="data[address][' + numberOfAddresses + ']" id="data[address][' + numberOfAddresses + ']" />';
var removeButton = '<button class="remove-address">Remove</button>';
var html = "<div class='address'>" + label + input + removeButton + "</div>";
$("#form1").find("#add-address").before(html);
});
});
$(document).on("click", ".remove-address",function(e){
e.preventDefault();
$(this).parents(".address").remove();
//update labels
$("#form1").find("label[for^='data[address]']").each(function(){
$(this).html("Address " + ($(this).parents('.address').index() + 1));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form1" method="post">
<div class="address">
<label for="data[address][0]">Address 1</label>
<input type="text" name="data[address][0]" id="data[address][0]" />
</div>
<button id="add-address">Add address</button>
<br />
<input type="submit" value="Submit" />
</form>
After form submit you can loop through addresses like this:
foreach ($_POST['data']['address'] as $address){
...your code
}
Hope this help! :)
Normally how I do this kind of stuff is to provide a user ability to add many input fields at client level and send them all in one array when submitting the form. That is more professional I believe. Try this JSFiddle to see what I mean.
<input type="text" name="address[]" />
if you want to POST dynamic value in a form you can do it like this:
<input type="text" name="adress[]" />
so in your case you could add new fields with javascript or jquery with the same name name="adress[]".
and in your PHP you get an array:
$adresses= $_POST['adress'];
foreach ($adresses as $adress) {
echo $adress;
}
FIDDLE DEMO
To process an array of inputs you can use the following convention:
HTML: simply add square brackets to the name attribute
<input type="text" id="data'+i+'" name="data[]" />
PHP: Post returns an array
for( $i=0; $i<$_POST["data"] ; $i++){
echo $_POST["data"][$i]."\n";
}
JAVASCRIPT: $("#form1").serialize() will retrieve all the inputs data as name=value pairs even the inputs that are added dynamically. There's no need to keep an array you can just process all of them at the end.
You don't need to create an array, $_POST is actually doing it all for you already.
So I suggest you do the following: using javascript (or jQuery), keep the button clicks, but make sure the form submission is prevented (using preventDefault on the form) [EDIT: You actually won't need this, as if the buttons are just buttons, no submit inputs, the form will not submit anyway], and just make sure you append another element every time they click a plus button or something; make sure you increment the name attributes of each input element that gets created.
When the user then creates submit, use submit the form via js, then on your getdata.php you can simply loop through all the values and use them that way you want. You will even be able to know the exact number by calculating the number of times a new input element has been added to the form.
I'll try to write up something for you in a minute, but if I was clear enough, you should be able to do that too.
EDITED: So here is what I've come up with; give it a try and see if this is something for you.
This is how the form would look like:
<form id="form1" name="myform" method="post" action="getdata.php">
Enter address 1: <input type="text" name="address-1" /> <input type="button" value="More" onclick="createNew()" />
<div id="mydiv"></div>
<input type="submit" value="Send" />
</form>
And this would be the js code:
var i = 2;
function createNew() {
$("#mydiv").append('Enter address ' + i +': <input type="text" name="address-' + i +'" /> <input type="button" value="More" onclick="createNew()" /><br />');
i++;
}
...and then getdata.php:
foreach ($_POST as $key => $value) {
echo 'The value for '.$key.' is: '.$value.'<br />';
}
here is a fiddle demo
I am a beginner, so keep that in mind.
so what I currently have working is my form successfully adds another input to the form, however it appears out of the form div. Basically I want it to appear within the div and above the submit button.
how do I do this?
here is main appendTo in my javascript:
var i = $('input').size() + 1;
$('a#add').click(function() {
$('<input type="text" value="user' + i + '" />').appendTo('form');
i++;
});
here is the form html as on request.
<div id="stylized" class="myform">
<form name="addstudents" method="post" action="add_students.php">
<div id="formHeader">
<h1>Add student(s)</h1>
<p>Please enter student's HEMIS number</p>
</div>
<label>Student: <span class="small">Enter HEMIS number</span> </label>
<input type='text' name="user_1">
<input type="submit" class="Mybutton" id="mybutton" name="submit" value='Submit Student(s)'>
<div class="spacer"></div>
</form>
AddRemove</div>
Any help would be greatly appreciated.
thanks
NEW PROBLEM: REMOVING!
here is my current remove JS, it simply removes the submit button first :(
$('a#remove').click(function() {
if(i > 3) {
$('input:last').remove();
i--;
}
});
$('a.reset').click(function() {
while(i > 2) {
$('input:last').remove();
i--;
}
});
Thanks again
You can use this snippet to insert the input before the button:
$('form #idofsubmitbutton').before($('<input type="text" value="user' + i + '" />'))
EDIT:
I played around with jsfiddle.com after your last edit and came upp with this:
var i = $('input').size() + 1;
$('a#add').click(function() {
$('div#stylized form input:submit').before($('<input type="text" value="user' + i + '" />'))
i++;
});
With the example html you posted this works. When I press the add link new inputs appear before the submit button.
If you still got problems you might have elements with duplicate ids.
var i = $('input').size() + 1;
$('a#add').click(function() {
$('<input type="text" value="user' + i + '" />').appendTo('div#divId');
i++;
});
This is not a "PHP form", once it's on the client, it's just HTML/CSS/Javascript. PHP is on the server.
.appendTo('form'); appends to the form TAG, not a "form div". If you have a DIV named "form" you need to use .appendTo('#form');
I have a webpage. There is a button called add. When this add button is clicked then 1 text box must be added. This should happen at client side only.
I want to allow the user to add at most 10 text boxes.
How can I achieve it using javascript?
example:
only 1 text box is displayed
user click add >
2 text boxes displayed
user clicks add >
I also wants to provide a button called "remove" by which the user can remove the extra text box
Can anyone provide me a javascript code for this??
Untested, but this should work (assuming an element with the right id exists);
var add_input = function () {
var count = 0;
return function add_input() {
count++;
if (count >= 10) {
return false;
}
var input = document.createElement('input');
input.name = 'generated_input';
document.getElementbyId('inputs_contained').appendChild(input);
}
}();
add_input();
add_input();
add_input();
A solution using the jQuery framework:
<form>
<ul class="addedfields">
<li><input type="text" name="field[]" class="textbox" />
<input type="button" class="removebutton" value="remove"/></li>
</ul>
<input type="button" class="addbutton" value="add"/>
</form>
The jQuery script code:
$(function(){
$(".addbutton").click(){
if(".addedfields").length < 10){
$(".addedfields").append(
'<li><input type="text" name="field[]" class="textbox" />' +
'<input type="button" class="removebutton" value="remove"/></li>'
);
}
}
// live event will automatically be attached to every new remove button
$(".removebutton").live("click",function(){
$(this).parent().remove();
});
});
Note: I did not test the code.
Edit: changed faulty quotation marks
I hope you are using jQuery.
