JQuery ajax在开关切换时执行多次

机器人先生

我有一个所有插座的表格列表，我有一个实体化 CSS 按钮来激活或停用插座，

@foreach($outlets as $outlet)
<tr>
    <td>
        <div class="switch m-b-md" data-id="{{$outlet->id}}">
            <label>
                @if($outlet->status == 'active')
                    <input id="agent-status" type="checkbox" checked="">
                @else
                    <input id="agent-status" type="checkbox">
                @endif
                <span class="lever"></span>
            </label>
        </div>
    </td>
</tr>
@endforeach

问题是当我点击.switchajax 执行多次时，如果我一直切换开关，它会执行超过 5 到 10 次

$(document).on("click", ".switch", function() {

    var outlet_id = $(this).data('id');

    $(".switch").find("input[type=checkbox]").on("change",function() {

        var status = $(this).prop('checked');

        if(status == true) {
            status = "active";
        } else {
            status = "inactive";
        }

        $.ajax ({
            url: '/manager/outlets/'+outlet_id+'/status',
            type: 'POST',              
            data: {"id": outlet_id, "status": status, "_token": '{{ csrf_token() }}'},
            success: function(data)
            {   
                if(data.status==true) {
                    swal("Updated", "Status updated successfully", "success");
                } else if(data.status==false) {
                    swal("Failed", "Fail to update status try again", "error");
                }
            },
            error: function(error)
            {
                swal("Failed", "Fail to update status try again", "error");
            }
        });

    });

});

谢谢你

您只需将事件侦听器分开并outlet_id用作闭包即可从两个侦听器访问它。见下文：

    var outlet_id;

    $(document).on("click", ".switch", function() {

        outlet_id = $(this).data('id');

    });

    $(".switch").find("input[type=checkbox]").on("change",function() {

        var status = $(this).prop('checked');

        if(status == true) {
            status = "active";
        } else {
            status = "inactive";
        }

        $.ajax ({
            url: '/manager/outlets/'+outlet_id+'/status',
            type: 'POST',
            data: {"id": outlet_id, "status": status, "_token": '{{ csrf_token() }}'},
            success: function(data)
            {
                if(data.status==true) {
                    swal("Updated", "Status updated successfully", "success");
                } else if(data.status==false) {
                    swal("Failed", "Fail to update status try again", "error");
                }
            },
            error: function(error)
            {
                swal("Failed", "Fail to update status try again", "error");
            }
        });

    });
