Answers:
var timeoutId = 0;
$('#myElement').on('mousedown', function() {
timeoutId = setTimeout(myFunction, 1000);
}).on('mouseup mouseleave', function() {
clearTimeout(timeoutId);
});
编辑:每个AndyE的更正...谢谢!
编辑2:现在为每个gnarf使用具有相同处理程序的两个事件使用bind
mouseleave
处理程序中的间隔。
.bind('mouseup mouseleave', function() {
空编码(但已在此提琴上进行了测试)
(function($) {
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);
})
大概您可以发起一个setTimeout
呼叫mousedown
,然后取消呼叫mouseup
(如果mouseup
发生在超时完成之前)。
但是,看起来好像有一个插件:longclick。
这是我当前的实现:
$.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它
//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!');
});

现在,您只需要设置保持时间并clickHold
在元素上添加事件
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);
});
