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") );
};

其他回答

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!

我还创造了一个更好的选择: https://stackoverflow.com/a/23692008/2829600 (支持“删除功能”)

原来的帖子:

我写了这个简单的函数来处理执行中的延迟,在jQuery .scroll()和.resize()中很有用,所以callback_f只会对特定的id字符串运行一次。

function delay_exec( id, wait_time, callback_f ){

    // IF WAIT TIME IS NOT ENTERED IN FUNCTION CALL,
    // SET IT TO DEFAULT VALUE: 0.5 SECOND
    if( typeof wait_time === "undefined" )
        wait_time = 500;

    // CREATE GLOBAL ARRAY(IF ITS NOT ALREADY CREATED)
    // WHERE WE STORE CURRENTLY RUNNING setTimeout() FUNCTION FOR THIS ID
    if( typeof window['delay_exec'] === "undefined" )
        window['delay_exec'] = [];

    // RESET CURRENTLY RUNNING setTimeout() FUNCTION FOR THIS ID,
    // SO IN THAT WAY WE ARE SURE THAT callback_f WILL RUN ONLY ONE TIME
    // ( ON LATEST CALL ON delay_exec FUNCTION WITH SAME ID  )
    if( typeof window['delay_exec'][id] !== "undefined" )
        clearTimeout( window['delay_exec'][id] );

    // SET NEW TIMEOUT AND EXECUTE callback_f WHEN wait_time EXPIRES,
    // BUT ONLY IF THERE ISNT ANY MORE FUTURE CALLS ( IN wait_time PERIOD )
    // TO delay_exec FUNCTION WITH SAME ID AS CURRENT ONE
    window['delay_exec'][id] = setTimeout( callback_f , wait_time );
}


// USAGE

jQuery(window).resize(function() {

    delay_exec('test1', 1000, function(){
        console.log('1st call to delay "test1" successfully executed!');
    });

    delay_exec('test1', 1000, function(){
        console.log('2nd call to delay "test1" successfully executed!');
    });

    delay_exec('test1', 1000, function(){
        console.log('3rd call to delay "test1" successfully executed!');
    });

    delay_exec('test2', 1000, function(){
        console.log('1st call to delay "test2" successfully executed!');
    });

    delay_exec('test3', 1000, function(){
        console.log('1st call to delay "test3" successfully executed!');
    });

});

/* RESULT
3rd call to delay "test1" successfully executed!
1st call to delay "test2" successfully executed!
1st call to delay "test3" successfully executed!
*/

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);

var flag=true;
var timeloop;

$(window).resize(function(){
    rtime=new Date();
    if(flag){
        flag=false;
        timeloop=setInterval(function(){
            if(new Date()-rtime>100)
                myAction();
        },100);
    }
})
function myAction(){
    clearInterval(timeloop);
    flag=true;
    //any other code...
}

这是我根据@Mark Coleman的答案写的代码:

$(window).resize(function() {
    clearTimeout(window.resizedFinished);
    window.resizedFinished = setTimeout(function(){
        console.log('Resized finished.');
    }, 250);
});
