How to keep focus on input first field

Question

I had a little complex task to do which I have already completed almost, but only stuck at one place

What I am doing

i have 3 input fields on my UI followed by a HTML table, the Input field is simple input field where user is going to input something
In my HTML table I have several input field to get input from user,initially there is only one row the first column is autocomplete from which user is selecting some data and according to that I am populating the next columns of that rows
When there is last Input field in my case it is Disc% so when user focusout from this I am creating new row with same functionality and the focus should shift to that new row's first column which is itemName

What my issue is

When I am loading the page the focus is automatically on itemName which is inside the table which I don't want
when page loads the focus should b on input field out side the table first, then if it is last input field outside the tble after focusout it should go in table's input field
In my code I think setTimeout(() => $("[name=itemNametd]", tbody).last().focus(), 100); this line is causing issue because when user focusout from the last input field of HTML table I am creating new row and focus shifts on new row's first column
I have commented the line where I think issue is

"use strict";
console.clear()


const data = [ //data to populate Item Name search input field

    "ItemName": "Butter"

Edit / Update

I have edited my code with correct data I have a datalist tag so on change of that I am creating the table row so when i change the datalist the focus shifts on the first column of the table row
In my actual I have structure like this after datalist I have so many input fields to fill up then want to go to table

Just use $("#dcNoInput").focus(), 100); to focus on that textbox.

What I have done is got that textbox element with its id and used .focus().

"use strict";
console.clear()
$("#dcNoInput").focus();

const data = [ //data to populate Item Name search input field
  {
    "ItemName": "Butter"
  },
  {
    "ItemName": "Rice"
  },
  {
    "ItemName": "Milk"
  },
  {
    "ItemName": "Ice Cream"
  },
  {
    "ItemName": "Curd"
  }
]

const data1 = { // this data will be dynamic but for now to test i am using this single data
  butter: {
    "ItemName": "Butter",
    "ItemCode": 400564,
    "PurRate": 8,
    "DiscAmt": 6,
    "gstPercentage": 35,
    "gstAmt": 5
  },
  rice: {
    "ItemName": "Rice",
    "ItemCode": 400565,
    "PurRate": 3,
    "DiscAmt": 2,
    "gstPercentage": 20,
    "gstAmt": 8
  },
  milk: {
    "ItemName": "Milk",
    "ItemCode": 200569,
    "PurRate": 1,
    "DiscAmt": 1,
    "gstPercentage": 50,
    "gstAmt": 2
  },
  'ice cream': {
    "ItemName": "Ice cream",
    "ItemCode": 800002,
    "PurRate": 16,
    "DiscAmt": 2,
    "gstPercentage": 15,
    "gstAmt": 2
  },
  curd: {
    "ItemName": "Curd",
    "ItemCode": 100289,
    "PurRate": 9,
    "DiscAmt": 1,
    "gstPercentage": 12,
    "gstAmt": 4
  },
}

var totalAmount = "";
var unitQuantity = "";

$("#supplierInput").on('input', function() {
  var dcInput = $("#dcInput").val();

    myCode();
  if(!dcInput){
    setTimeout(() => $("#dcInput").focus(), 110);
  }
});

function myCode() {
  function rowappend(tbody) { // this one is appending row{

    const markup =
      `<tr>
  <td>
    <input type="text" class="form-control commantd" name="itemNametd">

  <td name="totalAmttd" class="commantd"></td>

    $(tbody).append(markup);
    setTimeout(() => $("[name=itemNametd]", tbody).last().focus(), 100);

    const itemName = data.map(value => { //using autocomplete to for searching input field
      return value.ItemName;
    });
    $("[name=itemNametd]", tbody).last().autocomplete({
      source: itemName
    });

    const value = data1[search.toLowerCase()];
    if (value) {
      $(row).find("[name=itemCodetd]").text(value.ItemCode);
      $(row).find("[name=purRatetd]").text(value.PurRate);
      $(row).find("[name=discAmttd]").text(value.DiscAmt);
      $(row).find("[name=gstPercentahgetd]").text(value.gstPercentage);
      $(row).find("[name=gstAmttd]").text(value.gstAmt);
    }
  }



  function calc(row) {
    const unitQuantity = $(row).find("[name=unitQtytd]").val();
    const purchaseRate = $(row).find("[name=purRatetd]").text();
    const totalAmount = (parseInt(unitQuantity) * parseInt(purchaseRate));

    $(row).find("[name=totalAmttd]").text(totalAmount);

  }

No that will not work as when I will focus out from `Disc%` it will again focus on `DC No` which is not correct, Initially when page loads it should focus on `DC No` the when I `focusout` `Disc%` of table it should focus on new row which is created — manish thakur, Jun 20 '19 at 05:44
You need to focus on the `DC No` textbox. an when the row is added in the table it should focus on the first textbox of that row. is that right? if so the updated code is working fine — Syed mohamed aladeen, Jun 20 '19 at 06:15
no when I select any option from `datalist` it should focus on next textbox here i.e `DC Input` and after that it should go to tabels first row, if i change `setTimeout(() => $("[name=itemNametd]", tbody).last().focus(), 100);` to focus on `Dc Input` then while appending new row in table it will focus on `DC Input` which will not correct — manish thakur, Jun 20 '19 at 06:19

Very simple.Write this line of code inside document.ready() and let me know.

$("#YourFormId").find('input[type="text"]').first().focus();
