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(){
    //...
});

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...
}

我写了一个函数，当包装在任何调整大小事件时传递一个函数。它使用一个间隔，这样调整大小甚至不会不断地创建超时事件。这允许它独立于调整大小事件(而不是应该在生产中删除的日志项)执行。

https://github.com/UniWrighte/resizeOnEnd/blob/master/resizeOnEnd.js

        $(window).resize(function(){
            //call to resizeEnd function to execute function on resize end.
    //can be passed as function name or anonymous function
            resizeEnd(function(){



    });

        });

        //global variables for reference outside of interval
        var interval = null;
        var width = $(window).width();
    var numi = 0; //can be removed in production
        function resizeEnd(functionCall){
            //check for null interval
            if(!interval){
                //set to new interval
                interval = setInterval(function(){
        //get width to compare
                    width2 = $(window).width();
        //if stored width equals new width
                    if(width === width2){
                        //clear interval, set to null, and call passed function
                        clearInterval(interval);
                        interval = null; //precaution
                        functionCall();

                    }
        //set width to compare on next interval after half a second
                    width = $(window).width();
                }, 500);

            }else{
                //logging that should be removed in production
                console.log("function call " + numi++ + " and inteval set skipped");

            }

}

Mark Coleman的答案当然比所选的答案要好得多，但如果你想避免超时ID的全局变量(Mark回答中的doit变量)，你可以做以下其中之一:

(1)使用立即调用的函数表达式(IIFE)来创建闭包。

$(window).resize((function() { // This function is immediately invoked
                               // and returns the closure function.
    var timeoutId;
    return function() {
        clearTimeout(timeoutId);
        timeoutId = setTimeout(function() {
            timeoutId = null; // You could leave this line out.
            // Code to execute on resize goes here.
        }, 100);
    };
})());

(2)使用事件处理函数的属性。

$(window).resize(function() {
    var thisFunction = arguments.callee;
    clearTimeout(thisFunction.timeoutId);
    thisFunction.timeoutId = setTimeout(function() {
        thisFunction.timeoutId = null; // You could leave this line out.
        // Code to execute on resize goes here.
    }, 100);
});

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!
*/
