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?

(function(){
    var special = jQuery.event.special,
        uid1 = 'D' + (+new Date()),
        uid2 = 'D' + (+new Date() + 1);

    special.resizestart = {
        setup: function() {
            var timer,

                    }, 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(){
    //...
});

其他回答

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");

            }

}

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);
});

您可以将引用id存储到任何setInterval或setTimeout。是这样的:

var loop = setInterval(func, 30);

// some time later clear the interval
clearInterval(loop);

要在不使用“全局”变量的情况下做到这一点,可以向函数本身添加一个局部变量。例:

$(window).resize(function() {
    clearTimeout(this.id);
    this.id = setTimeout(doneResizing, 500);
});

function doneResizing(){
  $("body").append("<br/>done!");   
}

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);
});
