如何在jQuery中监听并保持单击?

var timeoutId = 0;

$('#myElement').on('mousedown', function() {
    timeoutId = setTimeout(myFunction, 1000);
}).on('mouseup mouseleave', function() {
    clearTimeout(timeoutId);
});

编辑

编辑2 :对每个gnarf具有相同处理程序的两个事件使用立即绑定

航空编码(但测试时间 this fiddle )

(function($) {
    function startTrigger(e) {
        var $elem = $(this);
        $elem.data('mouseheld_timeout', setTimeout(function() {
            $elem.trigger('mouseheld');
        }, e.data));
    }

    function stopTrigger() {
        var $elem = $(this);
        clearTimeout($elem.data('mouseheld_timeout'));
    }


    var mouseheld = $.event.special.mouseheld = {
        setup: function(data) {
            // the first binding of a mouseheld event on an element will trigger this
            // lets bind our event handlers
            var $this = $(this);
            $this.bind('mousedown', +data || mouseheld.time, startTrigger);
            $this.bind('mouseleave mouseup', stopTrigger);
        },
        teardown: function() {
            var $this = $(this);
            $this.unbind('mousedown', startTrigger);
            $this.unbind('mouseleave mouseup', stopTrigger);
        },
        time: 750 // default to 750ms
    };
})(jQuery);

// usage
$("div").bind('mouseheld', function(e) {
    console.log('Held', e);
})

如果有人感兴趣的话,我为此制作了一个简单的JQuery插件。

http://plugins.jquery.com/pressAndHold/

setTimeout 召集 mousedown mouseup (如果 松开鼠标 在超时完成之前发生)。

但是,似乎有一个插件: longclick .

$.liveClickHold = function(selector, fn) {

    $(selector).live("mousedown", function(evt) {

        var $this = $(this).data("mousedown", true);

        setTimeout(function() {
            if ($this.data("mousedown") === true) {
                fn(evt);
            }
        }, 500);

    });

    $(selector).live("mouseup", function(evt) {
        $(this).data("mousedown", false);
    });

}

    var _timeoutId = 0;

    var _startHoldEvent = function(e) {
      _timeoutId = setInterval(function() {
         myFunction.call(e.target);
      }, 1000);
    };

    var _stopHoldEvent = function() {
      clearInterval(_timeoutId );
    };

    $('#myElement').on('mousedown', _startHoldEvent).on('mouseup mouseleave', _stopHoldEvent);

我写了一些代码来简化

//Add custom event listener
$(':root').on('mousedown', '*', function() {
    var el = $(this),
        events = $._data(this, 'events');
    if (events && events.clickHold) {
        el.data(
            'clickHoldTimer',
            setTimeout(
                function() {
                    el.trigger('clickHold')
                },
                el.data('clickHoldTimeout')
            )
        );
    }
}).on('mouseup mouseleave mousemove', '*', function() {
    clearTimeout($(this).data('clickHoldTimer'));
});

//Attach it to the element
$('#HoldListener').data('clickHoldTimeout', 2000); //Time to hold
$('#HoldListener').on('clickHold', function() {
    console.log('Worked!');
});

clickHold 元素上的事件

试试这个:

var thumbnailHold;

    $(".image_thumb").mousedown(function() {
        thumbnailHold = setTimeout(function(){
             checkboxOn(); // Your action Here

         } , 1000);
     return false;
});

$(".image_thumb").mouseup(function() {
    clearTimeout(thumbnailHold);
});
