所以我目前使用的是:

$(window).resize(function(){resizedw();});

但是在调整大小过程中,这个函数会被调用很多次。是否有可能在事件结束时捕获事件?

窗口的ResizeStart和ResizeEnd事件

http://jsfiddle.net/04fLy8t4/

我实现了一个函数,它在用户DOM元素上触发两个事件:

调整大小开始 调整大小结束

代码:

var resizeEventsTrigger = (function () {
    function triggerResizeStart($el) {
        $el.trigger('resizestart');
        isStart = !isStart;
    }

    function triggerResizeEnd($el) {
        clearTimeout(timeoutId);
        timeoutId = setTimeout(function () {
            $el.trigger('resizeend');
            isStart = !isStart;
        }, delay);
    }

    var isStart = true;
    var delay = 200;
    var timeoutId;

    return function ($el) {
        isStart ? triggerResizeStart($el) : triggerResizeEnd($el);
    };

})();

$("#my").on('resizestart', function () {
    console.log('resize start');
});
$("#my").on('resizeend', function () {
    console.log('resize end');
});

window.onresize = function () {
    resizeEventsTrigger( $("#my") );
};
(function(){
    var special = jQuery.event.special,
        uid1 = 'D' + (+new Date()),
        uid2 = 'D' + (+new Date() + 1);

    special.resizestart = {
        setup: function() {
            var timer,
                handler =  function(evt) {
                    var _self = this,
                        _args = arguments;
                    if (timer) {
                        clearTimeout(timer);
                    } else {
                        evt.type = 'resizestart';
                        jQuery.event.handle.apply(_self, _args);
                    }

                    timer = setTimeout( function(){
                        timer = null;
                    }, special.resizestop.latency);
                };
            jQuery(this).bind('resize', handler).data(uid1, handler);
        },
        teardown: function(){
            jQuery(this).unbind( 'resize', jQuery(this).data(uid1) );
        }
    };

    special.resizestop = {
        latency: 200,
        setup: function() {
            var timer,
                handler = function(evt) {
                    var _self = this,
                        _args = arguments;
                    if (timer) {
                        clearTimeout(timer);
                    }
                    timer = setTimeout( function(){
                        timer = null;
                        evt.type = 'resizestop';
                        jQuery.event.handle.apply(_self, _args);
                    }, special.resizestop.latency);
                };

            jQuery(this).bind('resize', handler).data(uid2, handler);
        },
        teardown: function() {
            jQuery(this).unbind( 'resize', jQuery(this).data(uid2) );
        }
    };
})();

$(window).bind('resizestop',function(){
    //...
});

我很幸运地推荐了以下网站:http://forum.jquery.com/topic/the-resizeend-event

下面是代码,这样你就不必去挖掘他的帖子的链接和源代码:

var rtime;
var timeout = false;
var delta = 200;
$(window).resize(function() {
    rtime = new Date();
    if (timeout === false) {
        timeout = true;
        setTimeout(resizeend, delta);
    }
});

function resizeend() {
    if (new Date() - rtime < delta) {
        setTimeout(resizeend, delta);
    } else {
        timeout = false;
        alert('Done resizing');
    }               
}

谢谢森那美。Vidas for code!

这是我用来延迟重复操作的,它可以在你的代码中的多个地方调用:

function debounce(func, wait, immediate) {
    var timeout;
    return function() {
        var context = this, args = arguments;
        var later = function() {
            timeout = null;
            if (!immediate) func.apply(context, args);
        };
        var callNow = immediate && !timeout;
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
        if (callNow) func.apply(context, args);
    };
};

用法:

$(window).resize(function () { 
   debounce(function() {
          //...
    }, 500);
});

一种解决方案是用一个函数来扩展jQuery,例如:resize

$.fn.resized = function (callback, timeout) {
    $(this).resize(function () {
        var $this = $(this);
        if ($this.data('resizeTimeout')) {
            clearTimeout($this.data('resizeTimeout'));
        }
        $this.data('resizeTimeout', setTimeout(callback, timeout));
    });
};

示例用法:

美元(窗口)。大小(myHandler, 300);
