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

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!

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");

            }

}

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。

你可以使用setTimeout()和clearTimeout()

function resizedw(){
    // Haven't resized in 100ms!
}

var doit;
window.onresize = function(){
  clearTimeout(doit);
  doit = setTimeout(resizedw, 100);
};
