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

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)

其他回答

Internet Explorer提供一个resizeEnd事件。其他浏览器会在您调整大小时多次触发调整大小事件。

这里还有其他很好的答案,展示了如何使用setTimeout和lodash和下划线中的.throttle, .debounce方法,所以我将提到Ben Alman的throttle-debounce jQuery插件,它实现了你想要的东西。

假设你有这样一个函数,你想在调整大小后触发:

function onResize() {
  console.log("Resize just happened!");
};

节流阀的例子 在下面的例子中,onResize()在调整窗口大小的过程中只会每250毫秒调用一次。

$(window).resize( $.throttle( 250, onResize) );

防反跳的例子 在下面的例子中,onResize()只会在窗口调整动作结束时被调用一次。这与@Mark在他的回答中呈现的结果相同。

$(window).resize( $.debounce( 250, onResize) );

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;
}

这适用于我,因为我不想使用任何插件。

$(window).resize(function() {
    var originalWindowSize = 0;
    var currentWidth = 0;

    var setFn = function () {
        originalWindowSize = $(window).width();
    };

    var checkFn = function () {
        setTimeout(function () {
            currentWidth = $(window).width();
            if (currentWidth === originalWindowSize) {
                console.info("same? = yes") 
                // execute code 
            } else {
                console.info("same? = no"); 
                // do nothing 
            }
        }, 500)
    };
    setFn();
    checkFn();
});

在窗口重新大小调用“setFn”获得窗口的宽度,并保存为“originalWindowSize”。然后调用“checkFn”,在500ms(或您的首选项)后获得当前窗口大小,并将原始窗口与当前窗口进行比较,如果它们不相同,则窗口仍在重新调整大小。不要忘记在生产环境中删除控制台消息,并且(可选)可以使“setFn”自动执行。

更新!

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!
*/
