I'm manipulating cookie data for Scheduling Calendar.
I've array in cookie, using it i have made table. Now i want to delete table rows from last delete button of last column of the row.
My Code as given below
$cookie_data = '2017-06-27+06:00-06:30,2017-06-29+12:00-12:30,2017-07-01+06:00-12:00-17:00 ';
echo '<table class="table table-bordered" id="schedule">
<tr>
<th>Date</th>
<th>Times</th>
<th>Delete</th>
</tr>';
$val = $cookie_data;
$num_dates = explode(',',$val);
foreach($num_dates as $k => $v){
$bdata = explode('+',$v);
echo '<tr><td><label>'.$bdata[0].'</label></td><td><label>'.$bdata[1].'</label></td><td><button>Delete</button></td></tr>';
}
echo '</table>';
Also Code is running on phpfiddle.
http://phpfiddle.org/main/code/8ch0-merp
Now i want to remove any value by clicking delete button.
try with this,
Currently it will give error in fiddle. because stackoverflow not allowing to set custom cookie. So you can try this code at your side, and also i convert code in html so you have to convert in php.
You can set your cookie name as you want i just give example here.
Hope this will helps you :)
$("button").on("click",function() {
var cookieStr = $(this).attr("data-cookie");
var setCookieVal = [];
var cookieValue = $("#cookievalue").val().split(",");
for(i = 0; i< cookieValue.length; i++) {
if(cookieStr !== cookieValue[i]) {
setCookieVal.push(cookieValue[i]);
}
}
$.cookie("yourCookie",setCookieVal);
$(this).parent().parent().remove();
});

If do you want to delete cookie use $.dough in Jquery Plugin and for this you should specify name of the cookie like this example :
Create Cookie
//Code Starts
$.dough("cookieName", "cookieValue");
//Code Ends
Read Cookie
//Code Starts
$.dough("cookieName");
//Code Ends
Delete Cookie
//Code Starts
$.dough("cookieName", "remove");
//Code Ends

I am creating table, and want to remove row by id using input field. (if input field matches with id then the row must be deleted)
can not figure it out.
Your help is much appreciated
`
<body onload="addRow()">
<table id="myTable" style="display:none">
<tr>
<th class="borderless">ID</th>
<th>Name</th>
<th>Username</th>
<th>Gender</th>
<th>Country</th>
</tr>
<tbody id="myTableBody">
</tbody>
</table>
<button type="button" id="buttonShow" onclick="showTable()">Show Table</button>
<button type="button" id="buttonAdd" onclick="addRow()" disabled>Add a new row</button>
<br>
<label>
<input class="input1" type="text" name="todoTags"/>
<button class="dellbtn" id="buttonDell"onclick="delRow()" disabled>Delete row</button>
</label>
`
`
function showTable(){
document.getElementById("myTable").style.display = "block";
document.getElementById("buttonAdd").disabled = false;
document.getElementById("buttonDell").disabled = false;
}
const btn = document.querySelector('.dellbtn')
const userTags = []
`
Here is my: JSfiddle
What you could do is changing the addRow() method so it adds a data-attribute to each row, in the <tr>. You can achieve this goal by adding this when creating the row :
row.setAttribute("row-id", tr.length - 1);
Then, when you want to delete it, you can simply search the
row that has the data-attribute that you just input. And it will look like this :
function delRow() {
const value = document.getElementById("valueToDelete").value;
document.querySelector('[row-id="' + value + '"]').remove();
}
I created a fork to your JSFiddle that you can check right here.
Hope it helps ! Good luck :)
Not exactly what you're asking, but this method might work better for you. It uses a delete button for each row so you can decide which one to delete. Then it uses a delegate listener to enable the delete buttons
const table = document.querySelector('#theTable tbody');
let c = 1
const addRow = () => {
table.innerHTML += `<tr><td>${c} data</td><td>${c} data</td><td><button class='delete'>delete</button></td></tr>`;
c++
}
// delegate listener for the delete button
table.addEventListener('click', e => {
if (e.target.classList.contains('delete')) {
e.target.closest('tr').remove();
}
})
<table id='theTable'>
<th>
<tr>
<td>Col 1</td>
<td>Col 2</td>
<td></td>
</tr>
</th>
<tbody>
</tbody>
</table>
<button onclick='addRow()'>Add Row</button>
I have a table set up with the following headers. I have code set up to send ajax request to retrieve JSON data and brings up a dialog with a table when users clicks a button, and then I filter this data so it gives me a the filtered data back (e,g. Kevin). All the above is working good. Now I want to insert this data (Kevin) into the corresponding cell header (e.g. Name) and other data as well (Number->xxx-xxx-xxxx;address->xxx...etc). I want to do this so I make sure the data is inserted into the correct fields. I need to empty the row after user closes the dialog.
Javascript:
executeAPI("GetUserInfo.php", "name", callback); // this returns Kevin
function exeCtCoreAPIcallback(result){
//need to append the result to the corresponding cell header here.
}
HTML:
<table id="data-table">
<thead>
<tr id="data-row" class="data-header">
<th>Name</th>
<th>Number</th>
<th>Address</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<tr>
</tr>
</tbody>
</table>
Is there a way to reference the name of the <th> and insert below?
This is my solution:

I'm populating a table from my database and it looks like this :
<form name = "Form" role="form" action ="php/teilnehmen.php" method="POST">
<fieldset>
<table width="100%" class="table table-striped table-bordered table-hover" id="dataTables-example">

count($studienfaecherseperate);
for ($i; $i < $sizeofstudienfaecherseperate; $i++) {
?>
<tr class="odd gradeX">
<td ><?php echo($i+1);?></td>
<td class="studienfach"><?php echo($studienfaecherseperate[$i]);?>
<input type="hidden" name="PARAM_STUDIENFACH" id="PARAM_STUDIENFACH"
value="<?php echo($studienfaecherseperate[$i]);?>"> </input>
</td>
<td ><?php echo($teilnehmer[$i]);?></td>
<td width="10%">
<?php if ($teilnahmestatus[$i] =="0"){ ?>
<button type="submit" class="btn btn-success use-address"
name="teilnehmern"id="teilnehmen">Teilnehmen</button>
<?php }else{?>
<button type="submit" class="btn btn-danger use-address" name="teilnahme-beenden"
id="teilnahme-beenden">Teilnahme beenden</button>
<?php }?>
</td>
</tr>
<?php } ?>
</tbody>
</table>
</fieldset> <!-- /.table-responsive -->
the table is shown great, and my problem is when i try to submit my second column value "PARAM_STUDIENFACH" of a specific row to my php webservice. It always gives me back the last value. I know that because I'm using the same id in every row so it will be overwritten. I tried using JavaScript to return the value of the clicked row from other questions in the forum but it didn't work for me. I'm using a bootstrap table if that helps.
EDIT 1 :
Thanks to #Taplar answer I managed to find a solution to my problem. I used this JavaScript to retrieve the data and ajax to send a post request. This is the code I used :
$(".use-address").click(function() {
var item = $(this).closest("tr") // Finds the closest row <tr>
.find(".studienfach") // Gets a descendent with class="nr"
.text(); // Retrieves the text within <td>
$.ajax({
type: "POST",
dataType: "json",
url: "php/teilnehmen.php",
data: {PARAM_STUDIENFACH:item},
success: function(data){
alert(item);
},
error: function(e){
console.log(e.message);
}
});
});
my problem now is in the alert the "item" shows correctly but in my database it is saved as the following example :
item = a (shows in alert a)
item = a \n (it's saved like that in the database with spaces afeter \n)
i tried to trim the item before sending it but i got the same result
to get the item sent by ajax i'm using this line of code in :
$studienfach = null;
if(isset($_POST['PARAM_STUDIENFACH']))
$studienfach = $mysqli->real_escape_string($_POST['PARAM_STUDIENFACH']);
EDIT 2:
i managed to solve my second problem by doing this :
$pos= strpos($studienfach, "\\");
$studienfachtemp = substr($studienfach, 0,$pos);
trim($studienfachtemp);
if there is more elegent or correct way to do it ! please post it ! thank you all.
<elem1>
<elem2 class="getMe"></elem2>
<elem3></elem3>
</elem1>
Quick contextual lookup reference. Say you have a click event bound on all 'elem3' on your page. When you click it you want to get the associated 'elem2', not all of them. With the class you can contextually look this element up by doing...
//'this' being the elem3 that was clicked
$(this).closest('elem1').find('.getMe');
From the element you clicked, it will find the shared 'elem1' parent of both 'elem2' and 'elem3' and then find only the '.getMe' that belongs to that parent.

I try to change value by default with a calcul : value by default * quantity / 100. In my script something does not work because nothing happened, I can't find what! (jQuery is very new for me...)
$(function () {
$("#calcul").click(function (e) {
e.preventDefault();
var valeur = parseFloat($("#valquantite").text() );
$("#nutrition > tbody > tr").each(function () {
var valeurOrigin = parseFloat($(this).find("td").eq(1).text().replace(",", "."));
var newValeur;
if ($.isNumeric(valeurOrigin) === true) {
newValeur = valeurOrigin*valeur/100;
newValeur = Math.ceil(newValeur*1000)/1000;
} else {
newValeur = $(this).find("td").eq(1).text();
}
$(this).find("td").eq(2).html(newValeur);
});
});
});

What i try to do is that the first column after the name retrieves the quantities from a table (different for each row), then I retrieve the values by default columns energie_kj, energie_kcal, proteines, etc .. from a table (there are 60 Columns !! they are already calculated by default, I do not need to do any conversion). Some cells contain text (example: nc, traces, <) that I want to display as text. Then I have to calculate the total of each column (ignoring cells that contain text). That's my problem! I posted another question for the same problem with a code in js that works almost but not completely ... here: Javascript problems with NaN
Thanks in advance for your answers.
Hope this will help you. Replace your code with following : I've just parse your valeur variable and replaced > sign when calling .each function and applied Id=nutrition to table rather than tbody tag.
$(function () {
$("#calcul").click(function (e) {
e.preventDefault();
var valeur = parseInt($("#valquantite").text());
$("#nutrition tbody tr").each(function () {
var valeurOrigin = parseFloat($(this).find("td").eq(2).text().replace(",", "."));
var newValeur;
if ($.isNumeric(valeurOrigin) === true) {
newValeur = valeurOrigin*valeur/100;
newValeur = Math.ceil(newValeur*1000)/1000;
} else {
newValeur = $(this).find("td").eq(1).text();
}
$(this).find("td").eq(2).html(newValeur);
});
});

The issue may be, we don't know exactly what it is you're trying to calculate or where the data comes from. The valQuantite to which you refer, does that change for each row? If so, why is it defined outside of the each function? If not, why does it refer to a value from the first row of the table?
Doing a little research, you seem to want to take the quantity column and use that along with the energie kJ column to calculate... something. I'd suggest using classes for the three columns, valquantite, energie-kj, and energie-kcal, which you can then use to manipulate the individual columns in a meaningful way. Using $(this).find("td").eq(2).text() is only as good as the coder -- what if the column layout changes? Instead, simply use $(this).find(".energie-kj").text() and you're good.
Now, having gotten to displaying the kj as you'd like (by taking the qty and multiplying it by the kj, then rounding), you can calculate the kCal by dividing that number by 4.1868 and rounding as you'd like.
But note, I've modified your code -- the quantity seems to change with each row, so I've moved valQuantite inside the each statement. Also, I can't stress enough, I've commented my code to the point of silliness. Doing so makes it far easier to track what each line of code is SUPPOSED to be doing, as well as what it's actually doing. And use your console, it is your debugging FRIEND! lol
$(function() {
// When the button is clicked, calculate the values.
$("#calcul").click(function(e) {
// First, make sure the button doesn't submit...
e.preventDefault();
// Each row is handled individually, so
$("#nutrition > tbody > tr").each(function() {
// First, get the qty for this row
var valeur = parseFloat($(this).find(".valquantite").text());
/****
* Here is a case. We have hard-wired to use the
* third column of the table for the original val,
* but we could also add a class for this col and
* reference that: $(this).find(".energie-kj");
****/
var valeurOrigin = parseFloat($(this).find("td").eq(2).text().replace(",", "."));
var energyKJ, energyKCal;
// If the energie kJ value is numeric, we do the first
if ($.isNumeric(valeurOrigin) === true) {
// calculate some value from the energie kJ and qty,
energyKJ = valeurOrigin * valeur / 100;
// 1 kCal = 4.1868 kJ, so do the conversion
energyKCal = (energyKJ/4.1868).toFixed(2);
energyKJ = energyKJ.toFixed(2);
} else {
// If the energie kJ value is NOT numeric, we simply
// set the displayed value to this
newValeur = $(this).find("td").eq(2).text();
}
$(this).find(".energie-kj").text(energyKJ);
$(this).find(".energie-kcal").text(energyKCal);

I have a table where user can add data in it and I also have input field and save link. In my save link, if I click it.. I assign value to input field before it will go to other page. But when it go to the other page and I echo the value of inputfield, I got empty as in null value.
here's my code:
for table:
<table class="table " id="memberTB">
<thead>
<tr>
<th >First Name</th>
<th >Middle Name</th>
<th>Last Name</th>
</tr>
</thead>
<tbody>
<tr id="first">
<td><span class="edit"></span></td>
<td><span class="edit"></span></td>
<td><span class="edit"></span></td>
</tr>
</tbody>
<button type="button" class="btn btn-link" id="addrow">
<span class="fa fa-plus"> Add new row</span>
</button>
</table>
<input type="text" name="list" id="list"/>
<br>
<a class="btn" id="savebtn">Save</button>
Reset
and for js:
$('#savebtn').click(function() {
var cells = 3; //number of collumns
var arraylist = []
var x=0;
$('tbody tr',$('#memberTB')).each(function(){
var cell_text = '';
for(var i = 0 ; i < cells ; i++){
if(i==2){
cell_text =cell_text+$(this).find('td').eq(i).text()+":";
}else{
cell_text =cell_text+$(this).find('td').eq(i).text()+",";
}
}
arraylist.push(cell_text);
});
document.getElementById("list").value =arraylist;
document.getElementById("savebtn").href="<?php echo site_url('test/save');?>";
}
I got nothing when I echo it in the test.php in the save(), like this:
echo $this->input->post('list');
You are simply redirecting the page. So you will not get any value from post. If you want to get the value by post method you need to submit the value with a form.
<form id='save_form' method="post" action="<?php echo site_url('test/save');?>">
//add your html codes
//<table ..... and others
<a class="btn" href="#" id="savebtn">Save</button> //add # to href for save button
</form>
Now your js
$('#savebtn').click(function() {
//js codes that you wrote
//just replace the following line
//document.getElementById("savebtn").href="<?php echo site_url('test/save');?>";
$('#save_form').submit();
}
