非常感谢大卫沃尔什，这里是一个香草版本的下划线debounce。

代码:

// Returns a function, that, as long as it continues to be invoked, will not
// be triggered. The function will be called after it stops being called for
// N milliseconds. If `immediate` is passed, trigger the function on the
// leading edge, instead of the trailing.
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);
    };
};

简单的用法:

var myEfficientFn = debounce(function() {
    // All the taxing stuff you do
}, 250);

$(window).on('resize', myEfficientFn);

如果你安装了Underscore.js，你可以:

$(window).resize(_.debounce(function(){
    alert("Resized");
},500));

这是我实现的:

$（window）.resize（function（）{ setTimeout（someFunction， 500）; });

如果我们期望resize发生的时间小于500ms，我们可以清除setTimeout

祝你好运…

实际上，据我所知，当resize关闭时，您不能准确地执行某些操作，因为您不知道未来用户的操作。但是您可以假设两次调整大小事件之间的时间间隔，因此如果您等待的时间比这个时间稍长，并且没有进行调整大小，则可以调用您的函数。 我们使用setTimeout和它的id来保存或删除它。例如，我们知道两次调整大小事件之间的时间是500ms，因此我们将等待750ms。

var; $(窗口).resize(函数(){ clearTimeout(一个); a = setTimeout(函数(){ //调用函数 }, 750); });

简单的jQuery插件延迟窗口调整事件。

语法:

增加了调整事件大小的新功能

jQuery(window).resizeDelayed( func, delay, id ); // delay and id are optional

删除之前添加的函数(通过声明其ID)

jQuery(window).resizeDelayed( false, id );

删除所有功能

jQuery(window).resizeDelayed( false );

用法:

// ADD SOME FUNCTIONS TO RESIZE EVENT
jQuery(window).resizeDelayed( function(){ console.log( 'first event - should run after 0.4 seconds'); }, 400,  'id-first-event' );
jQuery(window).resizeDelayed( function(){ console.log('second event - should run after 1.5 seconds'); }, 1500, 'id-second-event' );
jQuery(window).resizeDelayed( function(){ console.log( 'third event - should run after 3.0 seconds'); }, 3000, 'id-third-event' );

// LETS DELETE THE SECOND ONE
jQuery(window).resizeDelayed( false, 'id-second-event' );

// LETS ADD ONE WITH AUTOGENERATED ID(THIS COULDNT BE DELETED LATER) AND DEFAULT TIMEOUT (500ms)
jQuery(window).resizeDelayed( function(){ console.log('newest event - should run after 0.5 second'); } );

// LETS CALL RESIZE EVENT MANUALLY MULTIPLE TIMES (OR YOU CAN RESIZE YOUR BROWSER WINDOW) TO SEE WHAT WILL HAPPEN
jQuery(window).resize().resize().resize().resize().resize().resize().resize();

使用输出:

first event - should run after 0.4 seconds
newest event - should run after 0.5 second
third event - should run after 3.0 seconds

插件:

jQuery.fn.resizeDelayed = (function(){

    // >>> THIS PART RUNS ONLY ONCE - RIGHT NOW

    var rd_funcs = [], rd_counter = 1, foreachResizeFunction = function( func ){ for( var index in rd_funcs ) { func(index); } };

    // REGISTER JQUERY RESIZE EVENT HANDLER
    jQuery(window).resize(function() {

        // SET/RESET TIMEOUT ON EACH REGISTERED FUNCTION
        foreachResizeFunction(function(index){

            // IF THIS FUNCTION IS MANUALLY DISABLED ( by calling jQuery(window).resizeDelayed(false, 'id') ),
            // THEN JUST CONTINUE TO NEXT ONE
            if( rd_funcs[index] === false )
                return; // CONTINUE;

            // IF setTimeout IS ALREADY SET, THAT MEANS THAT WE SHOULD RESET IT BECAUSE ITS CALLED BEFORE DURATION TIME EXPIRES
            if( rd_funcs[index].timeout !== false )
                clearTimeout( rd_funcs[index].timeout );

            // SET NEW TIMEOUT BY RESPECTING DURATION TIME
            rd_funcs[index].timeout = setTimeout( rd_funcs[index].func, rd_funcs[index].delay );

        });

    });

    // <<< THIS PART RUNS ONLY ONCE - RIGHT NOW

    // RETURN THE FUNCTION WHICH JQUERY SHOULD USE WHEN jQuery(window).resizeDelayed(...) IS CALLED
    return function( func_or_false, delay_or_id, id ){

        // FIRST PARAM SHOULD BE SET!
        if( typeof func_or_false == "undefined" ){

            console.log( 'jQuery(window).resizeDelayed(...) REQUIRES AT LEAST 1 PARAMETER!' );
            return this; // RETURN JQUERY OBJECT

        }

        // SHOULD WE DELETE THE EXISTING FUNCTION(S) INSTEAD OF CREATING A NEW ONE?
        if( func_or_false == false ){

            // DELETE ALL REGISTERED FUNCTIONS?
            if( typeof delay_or_id == "undefined" ){

                // CLEAR ALL setTimeout's FIRST
                foreachResizeFunction(function(index){

                    if( typeof rd_funcs[index] != "undefined" && rd_funcs[index].timeout !== false )
                        clearTimeout( rd_funcs[index].timeout );

                });

                rd_funcs = [];

                return this; // RETURN JQUERY OBJECT

            }
            // DELETE ONLY THE FUNCTION WITH SPECIFIC ID?
            else if( typeof rd_funcs[delay_or_id] != "undefined" ){

                // CLEAR setTimeout FIRST
                if( rd_funcs[delay_or_id].timeout !== false )
                    clearTimeout( rd_funcs[delay_or_id].timeout );

                rd_funcs[delay_or_id] = false;

                return this; // RETURN JQUERY OBJECT

            }

        }

        // NOW, FIRST PARAM MUST BE THE FUNCTION
        if( typeof func_or_false != "function" )
            return this; // RETURN JQUERY OBJECT

        // SET THE DEFAULT DELAY TIME IF ITS NOT ALREADY SET
        if( typeof delay_or_id == "undefined" || isNaN(delay_or_id) )
            delay_or_id = 500;

        // SET THE DEFAULT ID IF ITS NOT ALREADY SET
        if( typeof id == "undefined" )
            id = rd_counter;

        // ADD NEW FUNCTION TO RESIZE EVENT
        rd_funcs[id] = {
            func : func_or_false,
            delay: delay_or_id,
            timeout : false
        };

        rd_counter++;

        return this; // RETURN JQUERY OBJECT

    }

})();

这对我很管用。 请参阅此解决方案- https://alvarotrigo.com/blog/firing-resize-event-only-once-when-resizing-is-finished/

var resizeId; $(窗口).resize(函数(){ clearTimeout (resizeId); resizeId = setTimeout(doneResizing, 500); })； 函数doneResizing () { //我们想做的任何事情 ｝
