I am pretty new to jquery. I have the following code. Here I wants to get new rows in the table on clicking add button in Fill 3. I succeend to add that row, but when I get new divs then I wants to get new rows in the table on clicking add button in Fill 3. It added into wrong div.
can someone tell me what mistake I've done here?
var id = 0; //global id to create unique id
$(document).ready(function() {
//attach click event to element/button with id add and remove
$("#add,#remove").on('click', function() {
var currentElemID = $(this).attr('id'); //get the element clicked
if (currentElemID == "add") { //if it is add elem
var cloneParent = $("#dataTes").clone(); //clone the dataTes element
id=$("div[id^=dataTes]").length + 1;//get the count of dataTes element
//it will be always more than last count each time
cloneParent.find('[id]').each(function() {
//loop through each element which has id attribute in cloned set and replace them
//with incremented value
var $el = $(this); //get the element
$el.attr('id', $el.attr('id') + id);
//ids would now be add1,add2 etc.,
});
cloneParent.attr('id', cloneParent.attr('id') + id);//replace cloneParent id
cloneParent.appendTo('#result');//append the element to fieldset
$("#remove").show();//show remove button only if there is more than one dataTes element
} else {
$("div[id^=dataTes]:last").remove();
//just remove the last dataTes
//[id^=dataTes]:last annotates remove last div whose id begins with dataTes
//remember we have id like dataTes1,dataTes2 etc
if($("div[id^=dataTes]").length==1){
//check if only one element is present
$("#remove").hide();//if yes hide the remove button
}
}
});
});

</table>`
so what will we do here is that we will change addRow(this) instead of addRow('dataIp') because we know that "this" keyword has a high priority in terms of passing the ID of the element .. the "this" keyword has a general purpose vs passing of id into a function .. just try changing all parameter to the "this".
function addRow(tableID) {
var par = tableID.parentNode.parentNode.parentNode.id;
var table = document.getElementById(par);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for (var i = 0; i < colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
}
this is what ive done when I change the parameter of the add and delete function in your input i get the param parent node the element for the purpose of specific element inside the parent element...
}
by the way.. you must change your third index table to tbody. the result of getting the parentnode will be a tbody. because putting table inside a table is redundant window read it as tbody
we must follow the rule
<table>
<tbody>
</tbody>
<tfoot>
</tfoot>

I have a button that the user clicks on to add a new row to the bottom of an input table. I would like this to also increment the id. So the next row would have desc2, hours2, rate2 and amount2 as the id. Is there a way to do this in the JavaScript function.
Also - just want to check my logic on this. After the user completes the filled out form, I will be writing all the data to a mysql database on two different tables. Is this the best way to go about this? I want the user to be able to add as many lines in the desc_table as they need. If this is the correct way to be going about this, what is the best way to determine how many lines they have added so I can insert into the db table using a while loop?
JS file:
function new_line() {
var t = document.getElementById("desc_table");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
var x = rows[1].cloneNode(true);
x.style.display = "";
r.parentNode.insertBefore(x, r);
}
HTML:
<table id="desc_table">
<tr>
<td><font><br><h3>Description</h3></font></td>
<td><font><h3>Hours</h3></font></td>
<td><font><h3>Rate</h3></font></td>
<td><font><h3>Amount</h3></font></td>
<td></td>
</tr>
<tr>
<td ><textarea name="description" id="desc1" ></textarea></td>
<td> <input type="text" name="hours" id="hours1" ></td>
<td> <input type="text" name="rate" id="rate1"></td>
<td><input type="text" name="amount" id="amount1"></td>
<td>
<button type="button" name="add_btn" onclick="new_line(this)">+</button>
<button type="button" name="delete_btn" onclick="delete_row(this)">x</button>
</td>
</tr>
</table>
Thank you!
Check this code.After appending the row it counts the number of rows and and then assigns via if condition and incremental procedure the id's:
function new_line() {
var t = document.getElementById("desc_table");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
var x = rows[1].cloneNode(true);
x.style.display = "";
r.parentNode.insertBefore(x, r);
for(var i=1;i<rows.length;i++){
if(rows[i].children["0"].children["0"].id.match((/desc/g))){
rows[i].children["0"].children["0"].id='desc'+i;
}
if(rows[i].children["1"].children["0"].id.match((/hours/g))){
rows[i].children["1"].children["0"].id='hours'+i;
}
if(rows[i].children["2"].children["0"].id.match((/rate/g))){
rows[i].children["2"].children["0"].id='rate'+i;
}
if(rows[i].children["3"].children["0"].id.match((/amount/g))){
rows[i].children["3"].children["0"].id='amount'+i;
}
}
}
<table id="desc_table">
<tr>
<td><font><br><h3>Description</h3></font></td>
<td><font><h3>Hours</h3></font></td>
<td><font><h3>Rate</h3></font></td>
<td><font><h3>Amount</h3></font></td>
<td></td>
</tr>
<tr>
<td ><textarea name="description" id="desc1" ></textarea></td>
<td> <input type="text" name="hours" id="hours1" ></td>
<td> <input type="text" name="rate" id="rate1"></td>
<td><input type="text" name="amount" id="amount1"></td>
<td>
<button type="button" name="add_btn" onclick="new_line(this)">+</button>
<button type="button" name="delete_btn" onclick="delete_row(this)">x</button>
</td>
</tr>
</table>
Please change variable names for more descriptive. :)
Example solution...
https://jsfiddle.net/Platonow/07ckv5u7/1/
function new_line() {
var table = document.getElementById("desc_table");
var rows = table.getElementsByTagName("tr");
var row = rows[rows.length - 1];
var newRow = rows[rows.length - 1].cloneNode(true);
var inputs = newRow.getElementsByTagName("input");
for(let i=0; i<inputs.length; i++) {
inputs[i].id = inputs[i].name + rows.length;
}
var textarea = newRow.getElementsByTagName("textarea")[0];
textarea.id = textarea.name + rows.length;
table.appendChild(newRow);
}
Note that I removed/edited below fragment.
x.style.display = "";
r.parentNode.insertBefore(x, r);
You could do this a lot easier with jquery or another dom manipulation language, but with vanilla JS here's an example of simply looping through the new row's inputs & textarea and incrementing a counter to append.
var count = 1;
function new_line() {
count++;
var t = document.getElementById("desc_table");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
var x = rows[1].cloneNode(true);
x.style.display = "";
r.parentNode.insertBefore(x, r);
// update input ids
var newInputs = Array.from(x.getElementsByTagName('input'))
.concat(Array.from(x.getElementsByTagName('textarea')));
newInputs.forEach(function(input) {
var id = input.getAttribute('id').replace(/[0-9].*/, '');
input.setAttribute('id', id + count);
});
}
<table id="desc_table">
<tr>
<td><font><br><h3>Description</h3></font></td>
<td><font><h3>Hours</h3></font></td>
<td><font><h3>Rate</h3></font></td>
<td><font><h3>Amount</h3></font></td>
<td></td>
</tr>
<tr>
<td ><textarea name="description" id="desc1" ></textarea></td>
<td> <input type="text" name="hours" id="hours1" ></td>
<td> <input type="text" name="rate" id="rate1"></td>
<td><input type="text" name="amount" id="amount1"></td>

<button type="button" name="delete_btn" onclick="delete_row(this)">x</button>

I have gone through google and some of SO questions (such as this & this) as well but I didn't find the solution.
I am working for validation of a dynamically generated rows in a table,initially I am trying to validate the first td, loop and alert is working all fine but document.getElementById() is giving a null value. The script is at the very bottom of the page.

Because you are adding extra quotes in beginning and end in variable k. use:
var k = 'refNm_error' + (i+1);
You might need to reload the DOM after adding dynamic elements.
This link might help
Update, when you created your dynamic table rows for the table you didn't assign unique ids for input elements. So I updated the addRow handler:
$(document).on("click", ".addRowAux", function () {
to add unique input ids, like following:
$("#aux").append('<tr><td align="center">' + countrow + '</td><td align="center"><input type="text" name="ref_name[]" id="ref_name_' + countrow + '"/><span id="refNm_error_' + countrow + '">Please fill</span>...
and also I changed in the code:
<span id="removeRowaux">Remove</span>
to use class instead of an id:
<span class="removeRowaux">Remove</span>
Now the remove row handler listens to events from spans with class removeRowaux:
$(document).on('click', '.removeRowaux', function ()
Now the remove row functionality works and there are no spans with identical ids. So I don't think there was anything wrong with getElementById() in the code - it works fine :-)

I'm trying to create 2 dynamic html tables using Javascript with data from html inputs. I was able to create the first table I wanted but I've been unable to create 2 different tables using different inputs on the same page.
I tried changing the addRow() functions in the html and JS to have different names but this caused both tables to fail.
Any help would be appreciated. Here's the test code I've been using.
<!DOCTYPE html>
<body onload="load()">
<div id="myform">
<table>
<tr>
<td>Name:</td>
<td><input type="text" id="name"></td>
</tr>
<tr>
<td>Age:</td>
<td><input type="number" id="age">
<input type="button" id="add" value="Add" onclick="addRow()"></td>
</tr>

</tr>
</table>
<table id="myTableData2" border="1" cellpadding="2">
<tr>
<td> </td>
<td><b>Height</b></td>
<td><b>Width</b></td>
</tr>
</table>
</body>
</html>
function addRow() {
var myName = document.getElementById("name");
var age = document.getElementById("age");
var table = document.getElementById("myTableData");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML= '<input type="button" value = "Delete" onClick="deleteRow(this)">';
row.insertCell(1).innerHTML= myName.value;
row.insertCell(2).innerHTML= age.value;
var width = document.getElementById("width");
var height = document.getElementById("height");
var table2 = document.getElementById("myTableData2");
var rowCount2 = table2.rows.length;
var row2 = table2.insertRow(rowCount2);
row.insertCell(0).innerHTML = '<input type="button" value="Delete" onClick="deleteRow(this)">';
row.insertCell(1).innerHTML = width.value;
row.insertCell(2).innerHTML = height.value;
}
function deleteRow(obj) {
var index = obj.parentNode.parentNode.rowIndex;
var table = document.getElementById("myTableData");
table.deleteRow(index);
}
function load() {
console.log("Page load finished");
}
Looks like in the bottom section, you're not using the row2 variable you've defined.
Should be:
var rowCount2 = table2.rows.length;
var row2 = table2.insertRow(rowCount2);
row2.insertCell(0).innerHTML = '<input type="button" value="Delete" onClick="deleteRow(this)">';
row2.insertCell(1).innerHTML = width.value;
row2.insertCell(2).innerHTML = height.value;
here how i did it. you can use the same function for any amount of table, if pass the parameter in the function.
http://jsfiddle.net/8t5aqomk/2/
function myFunction(thisTable) {
var firstName = document.getElementById('firstName').value;
var lastName = document.getElementById('lastName').value;
var age = document.getElementById('age').value;
var info = [firstName,lastName,age]
var table = document.getElementById(thisTable);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cellCount = table.rows[0].cells.length;
for(var i=0; i<cellCount; i++) {
row.insertCell(i).innerHTML=info[i];
}
}
I know there are like thousands of answers on Stack Overflow about this specific topic, but I have been reading them for 3 days and nights already trying to apply solutions to my code with no success.
The problem is that addRow works fine, but DeleteRow doesn't work at all.
Here is my HTML:
<input type="button" value="add" onClick="addRow('dataTable')" />
<input type="button" value="delete" onclick="deleteRow(this)"/>
<p></p>
</p>

</table>
<div class="clear"></div>

javascript:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if (rowCount < 5) {
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for (var i = 0; i < colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
}
} else {
alert("Maksimālais ierakstu skaits ir 7.");
}
}
function DeleteRow(o) {
//no clue what to put here?
var p = o.parentNode.parentNode;
p.parentNode.removeChild(p);
}
Here is a fiddle with code working (only the addRow function): http://jsfiddle.net/7AeDQ/690/
Assuming you want to delete the last row, you can use something like this
function deleteRow() {
var table = document.getElementById("dataTable");
var tbody = table.tBodies[0];
tbody.removeChild(tbody.lastChild);
}
Updated fiddle here
Using something like this, you don't need to traverse the DOM using parentNode.parentNode...
I have an html table in my .aspx page which looks as follows:
<table id="quotationsListTable" class="quoteTbl" width="100%" border="1">
<tr>
<th></th>
<th>REF</th>
<th>Name</th>
<th>Arrival</th>
<th>Time</th>
<th>Departure</th>
<th>Time</th>
<th>Curr</th>
<th>Sale</th>
<th>Cost</th>
</tr>
<tr>
<td><input type="checkbox" name="chk"/></td>
<td> 1 </td>
<td><input type="text" style="width: 50px" /> </td>
<td><input type="text" style="width: 150px"/> </td>
<td> <input type="text" style="width: 50px"/> </td>
<td> <input type="text" style="width: 50px"/> </td>
<td> <input type="text" style="width: 50px"/> </td>
<td> <input type="text" style="width: 50px"/> </td>
<td> <input type="text" style="width: 50px"/> </td>
<td> <input type="text" style="width: 50px"/> </td>
</tr>
</table>
I also have a javascript function for deleting all the rows in my table, calling my by element ID "quotationsListTable".
The javascript function which stays in a separate .js file is a follows:
deleteAllrows('quotationsListTable');
function deleteAllrows(tableID) {
try {
var table = document.getElementByID(tableID);
var rowCount = table.rows.length;
for (var i = 1; i < rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
table.deleteRow(i);
rowCount--;
i--;
}
} catch (e) {
alert(e);
}
}
The problem at hand is that my js function cannot retrieve the table by id, the error message that is thrown is 'undefined'.
It's document.getElementById note the small d
var table = document.getElementById(tableID);
https://developer.mozilla.org/en-US/docs/DOM/document.getElementById
I suggest that you include the jquery library and remove the rows with single line .. check this fiddle http://jsfiddle.net/SamirAdel/DyXHt/
deleteAllrows('quotationsListTable');
function deleteAllrows(tableID) {
$("#"+tableID+"tr:gt(0)").remove()
}
You should set your function after the page content is ready.
And please, change your "getElementByID" to "getElementById", D um lowercase.
Try to use jQuery, is an easy way.
See:
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>
$().ready(function(){
deleteAllrows();
function deleteAllrows() {
try {
var table = document.getElementById('quotationsListTable');
alert(table);
var rowCount = table.rows.length;
for (var i = 1; i < rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
table.deleteRow(i);
rowCount--;
i--;
}
} catch (e) {
alert(e);
}
}
});
</script>
