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

就窗口管理器而言,每个调整大小事件都是它自己的消息,具有不同的开始和结束,因此从技术上讲,每次调整窗口大小时,它都是结束。

话虽如此,也许你想推迟你的延续?举个例子。

var t = -1;
function doResize()
{
    document.write('resize');
}
$(document).ready(function(){
    $(window).resize(function(){
        clearTimeout(t);
        t = setTimeout(doResize, 1000);
    });
});

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...
}

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) );

我不知道我的代码是否适用于其他人,但它对我来说真的很好。我通过分析Dolan Antenucci的代码得到了这个想法,因为他的版本不适合我,我真的希望它能对别人有所帮助。

var tranStatus = false;
$(window).resizeend(200, function(){
    $(".cat-name, .category").removeAttr("style");
    //clearTimeout(homeResize);
    $("*").one("webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend",function(event) {
      tranStatus = true;
    });
    processResize();
});

function processResize(){
  homeResize = setInterval(function(){
    if(tranStatus===false){
        console.log("not yet");
        $("*").one("webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend",function(event) {
            tranStatus = true;
        }); 
    }else{
        text_height();
        clearInterval(homeResize);
    }
  },200);
}

我自己写了一个小包装函数…

onResize  =   function(fn) {
    if(!fn || typeof fn != 'function')
        return 0;

    var args    = Array.prototype.slice.call(arguments, 1);

    onResize.fnArr    = onResize.fnArr || [];
    onResize.fnArr.push([fn, args]);

    onResize.loop   = function() {
        $.each(onResize.fnArr, function(index, fnWithArgs) {
            fnWithArgs[0].apply(undefined, fnWithArgs[1]);
        });
    };

    $(window).on('resize', function(e) {
        window.clearTimeout(onResize.timeout);
        onResize.timeout    = window.setTimeout("onResize.loop();", 300);
    });
};

用法如下:

var testFn  = function(arg1, arg2) {
    console.log('[testFn] arg1: '+arg1);
    console.log('[testFn] arg2: '+arg2);
};

// document ready
$(function() {
    onResize(testFn, 'argument1', 'argument2');
});

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!
*/
