您可以使用此代码。

var checkbox = document.getElementById("dlCheckAll4Delete");
checkbox.addEventListener("click", function (event) {
  let checkboxes = document.querySelectorAll(".dlMultiDelete");
  checkboxes.forEach(function (ele) {
    ele.checked = !!checkbox.checked;
  });
});

稍微改变的版本，检查和取消尊重

$('#select-all').click(function(event) {
        var $that = $(this);
        $(':checkbox').each(function() {
            this.checked = $that.is(':checked');
        });
    });

同一表单上可能有不同的复选框集。下面是一个通过类名选择/取消选择复选框的解决方案，使用普通javascript函数document.getElementsByClassName

全选按钮

<input type='checkbox' id='select_all_invoices' onclick="selectAll()"> Select All

要选择的一些复选框

<input type='checkbox' class='check_invoice' id='check_123' name='check_123' value='321' />
<input type='checkbox' class='check_invoice' id='check_456' name='check_456' value='852' />

javascript

    function selectAll() {
        var blnChecked = document.getElementById("select_all_invoices").checked;
        var check_invoices = document.getElementsByClassName("check_invoice");
        var intLength = check_invoices.length;
        for(var i = 0; i < intLength; i++) {
            var check_invoice = check_invoices[i];
            check_invoice.checked = blnChecked;
        }
    }

使用jQuery:

// Listen for click on toggle checkbox $('#select-all').click(function(event) { if(this.checked) { // Iterate each checkbox $(':checkbox').each(function() { this.checked = true; }); } else { $(':checkbox').each(function() { this.checked = false; }); } }); <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="checkbox" name="checkbox-1" id="checkbox-1" /> <input type="checkbox" name="checkbox-2" id="checkbox-2" /> <input type="checkbox" name="checkbox-3" id="checkbox-3" /> <!-- select all boxes --> <input type="checkbox" name="select-all" id="select-all" />

<asp:CheckBox ID="CheckBox1" runat="server" Text="Select All" onclick="checkAll(this);" />
<br />
<asp:CheckBoxList ID="CheckBoxList1" runat="server">
    <asp:ListItem Value="Item 1">Item 1</asp:ListItem>
    <asp:ListItem Value="Item 2">Item 2</asp:ListItem>
    <asp:ListItem Value="Item 3">Item 3</asp:ListItem>
    <asp:ListItem Value="Item 4">Item 4</asp:ListItem>
    <asp:ListItem Value="Item 5">Item 5</asp:ListItem>
    <asp:ListItem Value="Item 6">Item 6</asp:ListItem>
</asp:CheckBoxList>

<script type="text/javascript">
    function checkAll(obj1) {
        var checkboxCollection = document.getElementById('<%=CheckBoxList1.ClientID %>').getElementsByTagName('input');

        for (var i = 0; i < checkboxCollection.length; i++) {
            if (checkboxCollection[i].type.toString().toLowerCase() == "checkbox") {
                checkboxCollection[i].checked = obj1.checked;
            }
        }
    }
</script>

我不确定有人没有这样回答(使用jQuery):

  $( '#container .toggle-button' ).click( function () {
    $( '#container input[type="checkbox"]' ).prop('checked', this.checked)
  })

它是干净的，没有循环或if/else子句，工作就像一个魅力。
