Question

我的程序有问题。这是我的代码段。

这是Javascript / Jquery代码。

<script language='javascript'>

///SELECTING CHECKBOXES////
$(function(){

// add multiple select / deselect functionality
$("#selectall").click(function () {
      $('.case').attr('checked', this.checked);
});

// if all checkbox are selected, check the selectall checkbox
// and viceversa
$(".case").click(function(){

    if($(".case").length == $(".case:checked").length) {
        $("#selectall").attr("checked", "checked");
    } else {
        $("#selectall").removeAttr("checked");
    }

});
});
</script>

这是我将整合javascript的代码。

 <h2>Quotation ID</h2>

        $select_orders = mysql_query ("SELECT * FROM tblorder WHERE project_id = '$project_id' GROUP BY quotation_id") OR DIE (mysql_error());

            $quote_id = $row2['quotation_id'];

由于表在循环中。问题是第一个表出现时。并单击第一个标题复选框，它将检查其他表中的所有复选框。我不想发生这种事。我正在寻找的是，如果有一种方法，我也可以迭代复选框及其类的ID。或者还有其他方法可以做我想要发生的事情。

Here's a sample screen shot of the code output will be..

如你所见。那3个表有自己的复选框标题，我想在那里检查所有表格。你怎么知道我能做到这一点。

提前致谢..

Answer 1

你可以这样做。

$('.allcb').on('click', function(){
    var childClass = $(this).attr('data-child');
    $('.'+childClass+'').prop('checked', this.checked);
});

FIDDLE

<强>更新

只需将类allcb应用于主复选框，然后将子类复选框应用于名为chk的类。这应该符合您的需求。这是更新的 FIDDLE

Answer 2

使用.prop

$(function () {
    var $cases = $('.case');

    // add multiple select / deselect functionality
    var $all = $("#selectall").click(function () {
        $$cases.prop('checked', this.checked);
    });

    // if all checkbox are selected, check the selectall checkbox
    // and viceversa
    $cases.click(function () {
        $all.prop("checked", $cases.filter(":not(:checked)").length) != 0);
    });
});

Answer 3

尝试这个PHP代码而不是脚本 // check-all / uncheck-all复选框。

<a onclick="$(this).parent().find(':checkbox').attr('checked', true);"><?php echo $text_select_all; ?></a>/<a onclick="$(this).parent().find(':checkbox').attr('checked', false);"><?php echo $text_unselect_all; ?></a>

Answer 4

        $('#selectall').click(function () {
            if (this.checked) {

                $(':checkbox').each(function () {
                    this.checked = true;
                });
            }

             else {
                $(':checkbox').each(function () {
                    this.checked = false;
                }); 
             }  
        })

检查所有/取消选中循环语句中的所有Checkbox
