SelectAll checkbox to check only specific column

I have a somewhat working version of a datagrid with 2 columns of checkbox, 1 SelectAll checkbox in the header of second column. The issue right now is when I click the SelectAll, it will check/uncheck all checkbox in the datagrid.

I would like to have the SelectAll checkbox only check/uncheck the column it is in. Can someone help me on this? Thanks!

JavaScript

function SelectAllCheckboxesSpecific(spanChk) {

    var IsChecked = spanChk.checked;

    var Chk = spanChk;

    Parent = document.getElementById('dgPicsUploaded');

    var items = Parent.getElementsByTagName('input');

    for (i = 0; i < items.length; i++) {

        if (items[i].id != Chk && items[i].type == "checkbox") {

            if (items[i].checked != IsChecked) {

                items[i].click();

            }

        }

    }

}

DataGrid

<asp:TemplateColumn>

    <ItemStyle Wrap="true" Width="50px" />

    <HeaderTemplate>

        <asp:Button ID="btnSaveItemID" runat="server" Text="Save Item ID" OnClick="btnSaveItemID_Click" />

    <ItemTemplate>

        <asp:CheckBox ID="select2" runat="server" Checked="false"></asp:CheckBox>

Strangely, all the existing answers I could find are based on jQuery, gridview or some other library or framework, so I've added a POJS version. The only hard part is getting the column index, after that it's just a selector with forEach.

Provided the "select all" checkbox is in the same column as the checkboxes it applies to, you can get the cellIndex of its parent cell, then use that to find and check the checkboxes in the same column. A selector will likely do the job, if not a loop over the relevant rows getting the checkbox in the row.cells[index] checkbox.

Note that cellIndex is zero based, but nth-child starts at 1 so you need to add 1 to the index.

// Get nearest ancestor with tagName at or above node

function getNearest(tagName, node) {

  tagName = tagName.toLowerCase();

  while (node && node.tagName && node.tagName.toLowerCase() != tagName) {

    node = node.parentNode;

  }

  return node && node.tagName && node.tagName.toLowerCase() == tagName? node : null;

}



function checkAllInCol(evt) {

  var node = this;

  var cell = getNearest('th', node);

  if (!cell) return;

  var selector = `td:nth-child(${cell.cellIndex+1})`;

  var table = getNearest('table', cell);

  table.tBodies[0].querySelectorAll(selector).forEach(

    cell => cell.querySelector('input').checked = node.checked

  );

}



window.onload = function() {

  var cells = document.querySelectorAll('th input').forEach(cell => {

    cell.addEventListener('click', checkAllInCol, false);

  });

}

table {

  border-collapse: collapse;

  border-left: 1px solid #bbbbbb;

  border-top: 1px solid #bbbbbb;

}

th, td {

  border-right: 1px solid #bbbbbb;

  border-bottom: 1px solid #bbbbbb;

  text-align: right;

}

<table>

  <thead>

    <tr><th><label>Col 0: <input type="checkbox"></label>

        <th><label>Col 1: <input type="checkbox"></label>

  </thead>

  <tbody>

    <tr><td><input type="checkbox"><td><input type="checkbox"> 

    <tr><td><input type="checkbox"><td><input type="checkbox"> 

    <tr><td><input type="checkbox"><td><input type="checkbox">

  </tbody>

</table>

You should add error checking and validation, e.g. make sure cell.querySelector('input') returns a node before assigning to its checked property.

Thanks for the answer, but I end of using a bit of a cheat way to solve the issue. In my IF validation, I added the following && items[i].id.toString().indexOf("select2") == -1

– joseph.c
Nov 16 '18 at 18:39

@joseph.c—if you're going to use that approach, it would be much better to give them a class and select them using that, e.g. document.querySelectorAll('.select2').forEach((el, i, list) => el.checked = list[0].checked).

PS. Be careful with NodeList.forEach, it was added recently and may not be supported everywhere. An alternative is a plain loop or Array.from(NodeList).forEach(...).

Thanks for the answer, but I end of using a bit of a cheat way to solve the issue. In my IF validation, I added the following && items[i].id.toString().indexOf("select2") == -1

@joseph.c—if you're going to use that approach, it would be much better to give them a class and select them using that, e.g. document.querySelectorAll('.select2').forEach((el, i, list) => el.checked = list[0].checked).
