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?


当前回答

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");

            }

}

因为选择的答案实际上没有工作。如果你没有使用jquery,这里有一个简单的节流函数的例子,如何使用它来调整窗口大小

    function throttle(end,delta) {

    var base = this;

    base.wait = false;
    base.delta = 200;
    base.end = end;

    base.trigger = function(context) {

        //only allow if we aren't waiting for another event
        if ( !base.wait ) {

            //signal we already have a resize event
            base.wait = true;

            //if we are trying to resize and we 
            setTimeout(function() {

                //call the end function
                if(base.end) base.end.call(context);

                //reset the resize trigger
                base.wait = false;
            }, base.delta);
        }
    }
};

var windowResize = new throttle(function() {console.log('throttle resize');},200);

window.onresize = function(event) {
    windowResize.trigger();
}

有一个比计算两次调用之间的增量时间更简单的方法来在调整大小结束时执行函数,简单地像这样做:

var resizeId;
$(window).resize(function() {
    clearTimeout(resizeId);
    resizeId = setTimeout(resizedEnded, 500);
});

function resizedEnded(){
    ...
}

和Angular2的等价函数:

private resizeId;
@HostListener('window:resize', ['$event'])
onResized(event: Event) {
  clearTimeout(this.resizeId);
  this.resizeId = setTimeout(() => {
    // Your callback method here.
  }, 500);
}

对于angular方法,在setTimeout中使用()=>{}符号来保留作用域,否则你将无法进行任何函数调用或使用它。

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);
});

谢谢马克!

有一个优雅的解决方案使用下划线。js所以,如果你在你的项目中使用它,你可以做以下-

$( window ).resize( _.debounce( resizedw, 500 ) );

这应该足够了:)但是,如果你有兴趣阅读更多,你可以查看我的博客文章- http://rifatnabi.com/post/detect-end-of-jquery-resize-event-using-underscore-debounce(deadlink)

这是对上面Dolan代码的修改,我添加了一个功能,在调整大小开始时检查窗口大小,并将其与调整大小结束时的大小进行比较,如果大小大于或小于边缘(例如。1000)然后重新加载。

var rtime = new Date(1, 1, 2000, 12,00,00);
var timeout = false;
var delta = 200;
var windowsize = $window.width();
var windowsizeInitial = $window.width();

$(window).on('resize',function() {
    windowsize = $window.width();
    rtime = new Date();
    if (timeout === false) {
            timeout = true;
            setTimeout(resizeend, delta);
        }
});

function resizeend() {
if (new Date() - rtime < delta) {
    setTimeout(resizeend, delta);
    return false;
} else {
        if (windowsizeInitial > 1000 && windowsize > 1000 ) {
            setTimeout(resizeend, delta);
            return false;
        }
        if (windowsizeInitial < 1001 && windowsize < 1001 ) {
            setTimeout(resizeend, delta);
            return false;
        } else {
            timeout = false;
            location.reload();
        }
    }
    windowsizeInitial = $window.width();
    return false;
}
