vuejs creating onclick event from js method DOM

In my Vue CLI component, I'm populating a row table dynamically
i.e. inside my methods:
add_row() {
var new_name = document.getElementById("new_name").value;
var new_country = document.getElementById("new_country").value;
var new_age = document.getElementById("new_age").value;
var table = document.getElementById("data_table");
var table_len = table.rows.length - 1;
table.insertRow(table_len).outerHTML =
"<tr id='row" +
table_len +
"'><td id='name_row" +
table_len +
"'>" +
new_name +
"</td><td id='country_row" +
table_len +
"'>" +
new_country +
"</td><td id='age_row" +
table_len +
"'>" +
new_age +
"</td><td><input type='button' value='Delete' class='delete' #click=\"delete_row(" +
table_len +
')"></td></tr>';
document.getElementById("new_name").value = "";
document.getElementById("new_country").value = "";
document.getElementById("new_age").value = "";
}
This is the HTML part of the component:
<table
align="center"
cellspacing="2"
cellpadding="5"
id="data_table"
border="1"
>
<tr>
<th>Name</th>
<th>Country</th>
<th>Age</th>
</tr>
<tr id="row1">
<td id="name_row1">Ankit</td>
<td id="country_row1">India</td>
<td id="age_row1">20</td>
<td>
<input
type="button"
value="Delete"
class="delete"
#click="delete_row('1')"
/>
</td>
</tr>
<tr>
<td><input type="text" id="new_name" /></td>
<td><input type="text" id="new_country" /></td>
<td><input type="text" id="new_age" /></td>
<td>
<input
type="button"
class="add"
#click="add_row()"
value="Add Row"
/>
</td>
</tr>
</table>
Notice in my add_row function, when populating the row, I append a delete button tag and in it, pass the method delete_row. Clicking on this delete button should fire the method as shown below:
in my methods:
delete_row(no) {
document.getElementById("row" + no + "").outerHTML = "";
},
But the method is not being triggered from the delete_row function. I've confirmed that the rows are working well since my button for adding that row the add_row function fires. So my thinking is since I call the delete_row function from a dynamically created, there's perhaps something extra that I need to pass to my code to trigger this method?

How to get checked checkbox table value in jquery

In my table I have 2 rows please see my screen shot,suppose I click first check box means I want to take that id ** and **to_area value in jquery how can do this,I tried but I can not get please help some one
$(document).ready(function() {
$('#chemist_allotment_btn').click(function() {
if ($('#chemist_allotment_form').valid()) {
$.ajax({
url: 'update_chemist_bulk_transfer.php',
type: 'POST',
data: $('form#chemist_allotment_form').serialize(),
success: function(data) {
var res = jQuery.parseJSON(data); // convert the json
console.log(res);
if (res['status'] == 1) {
var htmlString = '';
$.each(res['data'], function(key, value) {
htmlString += '<tr>';
htmlString += ' <td class="sorting_1"><div class="checkbox-custom checkbox-success"><input type="checkbox" id="checkboxExample3" name="getchemist" class="getchemist" value="' + value.id + '"><label for="checkboxExample3"></label></div></td>';
htmlString += '<td>' + value.id + '</td>';
htmlString += '<td>' + value.name + '</td>';
htmlString += '<td>' + value.area + '</td>';
htmlString += '<td>' + value.to_area + '</td>';
htmlString += '<td>' + value.address + '</td>';
htmlString += '</tr>';
});
$('#SampleDT tbody').empty().append(htmlString);
$('#get_to_area').click(function() {
var id = $('input[name=getchemist]:checked').val();
if ($(".getchemist").prop('checked') == true) {
alert(id);
alert(value.to_area);
} else {
alert('Please Check');
}
});
} else {
$('#SampleDT tbody').empty().append('No Datas Found');
}
},
});
return false;
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="well white">
<table id="SampleDT" class="datatable table table-hover table-striped table-bordered tc-table">
<thead>
<tr>
<th>Select</th>
<th>Id</th>
<th>Doctor Name</th>
<th>From Area</th>
<th>To Area</th>
<th>Address</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<center>
<div class="form-group">
<button type="button" class="btn btn-primary" style="text-align:left;" id="get_to_area">Transfer Area</button>
</div>
</center>
</div>

Firstly, add classes to each <td>, like <td class='id'>[Your id]</td>
Similarly for all the elements doctor-name, to-area, etc and a class to each <tr> like row-select
Somewhat like this:
<tr class="row-select">
<td class="select">...</td>
<td class="id">...</td>
<td class="to-area">...</td>
.
.
.
</tr>
Use jQuery like this:
$('.row-select').click(function(){
var id,toArea,checkBox;
id = $(this).find('.id').html(); //get the ID field
toArea = $(this).find('.to-area').html(); //get the to-area field
checkBox = $(this).find('.select > input');
checkbox.prop('checked',!checkbox.prop('checked'));
})
This code will get you he value no mater where you click on the row, and also invert the selection on the checkbox
To get the values of rows selected when the form is submitted run a loop like this
$('.row-select input:checked').each(function(){
var id,toArea,checkBox;
id = $(this).closest('tr').find('.id').html(); //get the ID field
toArea = $(this).closest('tr').find('.to-area').html(); //get the to-area field
})
EDIT
All together:
$(document).ready(function() {
$('#btnSubmit').click(function() {
$('.row-select input:checked').each(function() {
var id, name;
id = $(this).closest('tr').find('.id').html();
name = $(this).closest('tr').find('.name').html();
alert('ID: ' + id + " | Name: " + name);
})
})
$('#btnSelectAll').click(function() {
$('.row-select input').each(function() {
$(this).prop('checked', true);
})
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border=1>
<tr class="row-select">
<td class="check">
<input type="checkbox" />
</td>
<td class="id">12</td>
<td class="name">Jones</td>
</tr>
<tr class="row-select">
<td class="check">
<input type="checkbox" />
</td>
<td class="id">10</td>
<td class="name">Joseph</td>
</tr>
</table>
<button id="btnSelectAll">Select all</button>
<button id="btnSubmit">Get Value</button>

Process step-by-step:
Give the td you need some classes (from-a & to-a);
Initialize an empty array all (we'll store the data inside it later on);
Create a function that is triggered by the checkbox change
Inside the function you need to know which checkbox has changed, what's the state of it, what tr does it belong to and at the end what are the TO AREA and FROM AREA values.
If the state = checked we will add the values to the all (our small data storage);
If the state = not-checked we will remove the value from the all array;
Finally when we are done with selecting and deselecting rows by pressing the button we can get the values of the selected rows.
var all = [];
$('input[type="checkbox"]').change(function(){
var checkbox = $(this);
var state = checkbox.prop('checked');
var tr = checkbox.parents('tr');
var from = tr.children('.from-a').text();
var to = tr.children('.to-a').text();
if(state){
all.push(from + ' -> ' + to);
}else{
var index = all.indexOf(from + ' -> ' + to);
all.splice(index, 1);
}
})
$('#get_to_area').click(function(){
alert(all);
});

This is just the basic concept, you can modify it to suit your needs, I'll be happy to help you if you get stuck.

You can also use this fiddle:
In JS:
$('#get_to_area').click(function () {
var id = $('input[name=getchemist]:checked').val();
if ($('input[name=getchemist]').is(':checked')) {
var ID = $('input[name=getchemist]').parent().parent().siblings('td.chkid').html();
var TO_Area = $('input[name=getchemist]').parent().parent().siblings('td.toarea').html();
}
else {
alert('Please Check');
}
});
In Html:
if (res['status'] == 1) {
var htmlString = '';
$.each(res['data'], function (key, value) {
htmlString += '<tr>';
htmlString += ' <td class="sorting_1"><div class="checkbox-custom checkbox-success"><input type="checkbox" id="checkboxExample3" name="getchemist" class="getchemist" value="' + value.id + '"><label for="checkboxExample3"></label></div></td>';
htmlString += '<td class="chkid">' + value.id + '</td>';
htmlString += '<td>' + value.name + '</td>';
htmlString += '<td>' + value.area + '</td>';
htmlString += '<td class="toarea">' + value.to_area + '</td>';
htmlString += '<td>' + value.address + '</td>';
htmlString += '</tr>';
});

I'm guessing you need values of each td whose checbox are checked. This piece of code should get you started.
As you can see, Code loops through each checkbox which is checked, gets contents inside its corresponding td.
var Result = new Array();
$('.checkbox-custom input[type="checkbox"]:checked').each(function(){
var _this = $(this).closest('tr').find('td');
var id= $(_this).eq(0);
var name = $(_this).eq(1);
................... //Similar way for the others
Result.Push(id,name,....)
});

Incrementing id attribute value through javascript

I am trying to dynamically add rows to a table to take orders and have created a javascript function for it.
function addnewrow()
{
var lastid = $("#table tr:last").attr("id");
var newid=lastid+1;
var newcolumn = document.createElement("tr");
newcolumn.id=newid;
newcolumn.innerHTML = "<td id='no"+newid+"'><a class='cut'>-</a>"+newid+"</td>"+
"<td>"+
"<ajaxToolkit:ComboBox ID='prod"+newid+"' runat='server' DataSourceID='SqlDataSource2' DataTextField='pname' DataValueField='pid' MaxLength='0' style='display: inline;'></ajaxToolkit:ComboBox>" +
"</td>"+
"<td><input type='number' required='required' min='1' name='quantity" + newid + "' /></td>" +
"<td id='price" + newid + "'></td>" +
"<td id='amount" + newid + "'></td>";
document.getElementById("table").appendChild(newcolumn);
}
I am doing this to get the values of all the elements in the code behind file to put them in database.
but due to this i get an error in the aspx.designer.cs page saying semicolon expected
protected global::AjaxControlToolkit.ComboBox prod" + newid + ";
ASP.NET Code
<table class="Grid" id="table">
<tr>
<td colspan="5">Enter Order Details</td>
</tr>
<tr>
<th>Sr No.</th>
<th>Product</th>
<th>Quantity</th>
<th>Price</th>
<th>Amount</th>
</tr>
<tr id="1">
<td><a class="cut">-</a>1</td>
<td>
<ajaxToolkit:ComboBox ID="prod1" runat="server" DataSourceID="SqlDataSource2" DataTextField="pname" DataValueField="pid" MaxLength="0" style="display: inline;"></ajaxToolkit:ComboBox>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:micoConnectionString %>" SelectCommand="SELECT [pid], [pname] FROM [Products]"></asp:SqlDataSource>
</td>
<td><input type="number" required="required" min="1" name="quantity1" /></td>
<td id="price1"></td>
<td id="amount1"></td>
</tr>
</table>
<a class="add" onclick="addnewrow()" href="#">+</a>

Check this
$("#btnAddSchedule").click(function () {
var trs = $("[id^=trSchedules]");
var numberofrows = trs.length;
var newtr = $('#' + trs[0].id).clone();
$(newtr).attr('id', $(newtr).attr('id').replace(/\d+/, numberofrows));
newtr.find("input,select,img").each(function () {
$(this).attr('id', $(this).attr('id').replace(/\d+/, numberofrows));
$(this).attr('name', $(this).attr('name').replace(/\d+/, numberofrows));
if ($(this).attr('type') != "hidden") {
$(this).val('');
}
else if ($(this).attr('id').indexOf('DataExportQueueID') == -1) {
$(this).val('');
}
if ($(this).attr("type") == "checkbox") {
$(this).removeAttr("checked");
$(this).parent().html($(this).parent().html().replace(/\d+/g, numberofrows));
}
if ($(this).attr("type") == "button") {
$(this).attr("onclick", "deleteSchedule(this,0);");
}
});
$('#' + trs[numberofrows - 1].id).after(newtr);
CrossCheckScheduleRows();
});
function CrossCheckScheduleRows() {
$('[id^=trSchedules]').each(function () {
var row = $(this);
var index = row[0].rowIndex - 2;
row.attr('id', row.attr('id').replace(/\d+/, index));
row.find("input,select,img").each(function () {
$(this).attr('id', $(this).attr('id').replace(/\d+/, index)).attr('name', $(this).attr('name').replace(/\d+/, index));
});
});
}
I use this for the same purpose, maybe it will help you

Delete function in JavaScript

I trying to delete row from a table but somehow is not working. Could please let me know how can I solve this one ?
here is my html with table and javascript:
<tbody class="items">
<tr>
<td> Data 1 </td>
<td> Data 2 </td>
</tr>
</tbody>
<tbody id="test">
<tr>
<td> </td>
<td> </td>
</tr>
</tbody>
$(".items tr").click(function() {
var value = parseInt($.trim(tableData[1]));
$("#test").append(
"<tr><td><input name='sm_invnumber[]' value='" +
$.trim(tableData[0]) +
"' style='width: 170px;' readonly ></td><td><input name='sm_amount[]' value='" +
$.trim(tableData[1]) +
"' style='width: 170px; text-align: right;' readonly ></td><td><span onclick='deleteRow(value, this)'> x </span> </td></tr>");
});
function deleteRow(value, row) {
var i = row.parentNode.parentNode.rowIndex;
document.getElementById('#test').deleteRow(i);
}
Here is the instruction that I am working with: Picking data by clicking on table (class= items) and place to them into table (id=test). there is a function with 'X'. I want to delete this row.
Helps are highly appreciated.

You seem to making your life very difficult. Why not simply add a class to the cell that has the cross and use jQuery to remove its containing row. For example:
<table>
<tbody id="test">
<tr><td>Data 1</td><td class="delete">x</td></tr>
<tr><td>Data 2</td><td class="delete">x</td></tr>
<tr><td>Data 3</td><td class="delete">x</td></tr>
</tbody>
</table>
$('.delete').click(function () {
$(this).parent().remove();
});
Fiddle

try this
function deleteRow(value, span)
{
$(span).closest("tr").remove();
}
or
function deleteRow(value, span)
{
var i=row.parentNode.parentNode.rowIndex;
$(document.getElementById('test')).children(":eq("+i+")").remove();
}

There are few poblems, try
jQuery(function () {
var tableData = [1, 'test'];
$(".items tr").click(function () {
var value = parseInt($.trim(tableData[1]));
$("#test").append(
"<tr><td><input name='sm_invnumber[]' value='" + $.trim(tableData[0]) + "' style='width: 170px;' readonly ></td><td><input name='sm_amount[]' value='" + $.trim(tableData[1]) + "' style='width: 170px; text-align: right;' readonly ></td><td><span onclick='deleteRow(\"" + value + "\",this)'> x </span> </td></tr>");
});
})
function deleteRow(value, row) {
$(row).closest('tr').remove();
}

Datatables using JSON response

I'm trying to load a JSON response from Google Shopping into a table in html formatted using DataTables, the JQuery plugin.
I'm appending the data to the table div but it does not seem to be working.

success: function(data) {
$.each(data.items, function(i, item){

var title = item.product.title;
var gtin = item.product.gtins[0];
//price
var currency = item.product.inventories[0]['currency'];
var price = item.product.inventories[0]['price'];
var shipping = item.product.inventories[0]['shipping'];
var listData = "<li>" + title + gtin + price + currency + shipping + "</li>" + '<img title="' + title + '" src="' + link + '" />';
var dataTable =
"<tr>" +

$('#example').append(dataTable).hide().fadeIn('slow');
console.log(data)
}
});
}
});
});
});
Update: With Larry's help, I've managed to get the data loading into the table. I know this as the number at the bottom is populated. However, the data is not displaying at all.

Assuming that your AJAX call is working and returning data, the proper way to append a row to a jQuery dataTable is not to attempt to edit the underlying HTML but rather to have dataTable add the row through the dataTable API call fnAddData().
There is an example here.
