jQuery Checkbox事件被累积添加

时间：2017-10-09 10:15:10

标签： jquery events checkbox event-handling

这个逻辑的目标是： -

  1. 要在复选框上打开引导模式，请单击
  2. 在模式中有两个按钮，用于确认或取消该选项。
  3. 只有受影响的复选框

    4. 问题是，当单击多个复选框时，它们共享相同的事件，您单击的次数越多，受影响的越多。我已经尝试了各种解决方案来尝试让点击事件仅影响该特定复选框，尽管我没有幸运获得最后一点。

    我真的很感激任何帮助！

所以我用.unbind'事件处理程序类型'解决了它。 

  confirm.unbind("click");
  cancel.unbind("click");

http://api.jquery.com/unbind/

删除了以前堆叠的事件。但是，如果没有强制模式关闭并重置事件以重新开始，则不起作用。

总的来说，它最终看起来像这样：

 //listen for a click on the checkbox
    var confirm = $('#validationConfirm');
    var cancel = $('#validationCancel');

    function modalCheck(e, element) {
        console.log(e.srcElement.checked)
        //confirm button
        if (amIclicked(e, element)) {
            var confirmClick = confirm.click(function () {

                element.checked = true
                    confirm.unbind("click");
                    cancel.unbind("click");

                //closes modal
                    $(function () {
                        $('#validationModal').modal('toggle');
                    });
            });
        }
        //cancel button
        if (amIclicked(e, element)) {
            var cancelClick = cancel.click(function () {
                element.checked = false

                confirm.unbind("click");
                cancel.unbind("click");

                //closes modal
                $(function () {
                    $('#validationModal').modal('toggle');
                });
            });
        }
    }

    function amIclicked(e, element) {
        e = e || event;
        var target = e.target || e.srcElement;
        if (target.id == element.id)
            return true;
        else
            return false;
    }
