您必须将resize事件绑定到窗口对象上，而不是绑定到通用html元素上。

然后你可以使用这个:

$(window).resize(function() {
    ...
});

在回调函数中，你可以检查div调用的新宽度

$('.a-selector').width();

因此，您的问题的答案是否定的，您不能将resize事件绑定到div。

纯香草的实现。

var move = function(e) { if ((e.w && e.w !== e.offsetWidth) || (e.h && e.h !== e.offsetHeight)) { new Function(e.getAttribute('onresize')).call(e); } e.w = e.offsetWidth; e.h = e.offsetHeight; } var resize = function(e) { e.innerText = 'New dimensions: ' + e.w + ',' + e.h; } .resizable { resize: both; overflow: auto; width: 200px; border: 1px solid black; padding: 20px; } <div class='resizable' onresize="resize(this)" onmousemove="move(this)"> Pure vanilla implementation </div>

我认为这是不可能的，但后来我想了一下，你可以手动调整一个div通过style="resize: both;"为了做到这一点，你必须点击它，所以添加了一个onclick函数来检查元素的高度和宽度，它工作。只有5行纯javascript(当然可以更短) http://codepen.io/anon/pen/eNyyVN

<div id="box" style="
                height:200px; 
                width:640px;
                background-color:#FF0066;
                resize: both;
                overflow: auto;" 
                onclick="myFunction()">
    <p id="sizeTXT" style="
                font-size: 50px;">
       WxH
    </p>
    </div>

<p>This my example demonstrates how to run a resize check on click for resizable div.</p>

<p>Try to resize the box.</p>


<script>
function myFunction() {
var boxheight = document.getElementById('box').offsetHeight;
var boxhwidth = document.getElementById('box').offsetWidth;
var txt = boxhwidth +"x"+boxheight;
document.getElementById("sizeTXT").innerHTML = txt;
}
</script>

唯一的窗户。onResize存在于规范中，但你总是可以利用IFrame在DIV中生成新的Window对象。

请核对这个答案。有一个新的jquery插件，它是可移植的，易于使用。您总是可以检查源代码，看看它是如何完成的。

<!-- (1) include plugin script in a page -->
<script src="/src/jquery-element-onresize.js"></script>

// (2) use the detectResizing plugin to monitor changes to the element's size:
$monitoredElement.detectResizing({ onResize: monitoredElement_onResize });

// (3) write a function to react on changes:
function monitoredElement_onResize() {    
    // logic here...
}

ResizeSensor.js是一个巨大库的一部分，但我把它的功能简化为:

function ResizeSensor(element, callback)
{
    let zIndex = parseInt(getComputedStyle(element));
    if(isNaN(zIndex)) { zIndex = 0; };
    zIndex--;

    let expand = document.createElement('div');
    expand.style.position = "absolute";
    expand.style.left = "0px";
    expand.style.top = "0px";
    expand.style.right = "0px";
    expand.style.bottom = "0px";
    expand.style.overflow = "hidden";
    expand.style.zIndex = zIndex;
    expand.style.visibility = "hidden";

    let expandChild = document.createElement('div');
    expandChild.style.position = "absolute";
    expandChild.style.left = "0px";
    expandChild.style.top = "0px";
    expandChild.style.width = "10000000px";
    expandChild.style.height = "10000000px";
    expand.appendChild(expandChild);

    let shrink = document.createElement('div');
    shrink.style.position = "absolute";
    shrink.style.left = "0px";
    shrink.style.top = "0px";
    shrink.style.right = "0px";
    shrink.style.bottom = "0px";
    shrink.style.overflow = "hidden";
    shrink.style.zIndex = zIndex;
    shrink.style.visibility = "hidden";

    let shrinkChild = document.createElement('div');
    shrinkChild.style.position = "absolute";
    shrinkChild.style.left = "0px";
    shrinkChild.style.top = "0px";
    shrinkChild.style.width = "200%";
    shrinkChild.style.height = "200%";
    shrink.appendChild(shrinkChild);

    element.appendChild(expand);
    element.appendChild(shrink);

    function setScroll()
    {
        expand.scrollLeft = 10000000;
        expand.scrollTop = 10000000;

        shrink.scrollLeft = 10000000;
        shrink.scrollTop = 10000000;
    };
    setScroll();

    let size = element.getBoundingClientRect();

    let currentWidth = size.width;
    let currentHeight = size.height;

    let onScroll = function()
    {
        let size = element.getBoundingClientRect();

        let newWidth = size.width;
        let newHeight = size.height;

        if(newWidth != currentWidth || newHeight != currentHeight)
        {
            currentWidth = newWidth;
            currentHeight = newHeight;

            callback();
        }

        setScroll();
    };

    expand.addEventListener('scroll', onScroll);
    shrink.addEventListener('scroll', onScroll);
};

如何使用:

let container = document.querySelector(".container");
new ResizeSensor(container, function()
{
    console.log("dimension changed:", container.clientWidth, container.clientHeight);
});

有一种非常有效的方法来确定元素的大小是否已经改变。

http://marcj.github.io/css-element-queries/

这个库有一个resizessensor类，可以用于调整大小检测。它使用基于事件的方法，所以它非常快，而且不会浪费CPU时间。

例子:

new ResizeSensor(jQuery('#divId'), function(){ 
    console.log('content dimension changed');
});

请不要使用jQuery onresize插件，因为它使用setTimeout()结合在循环中读取DOM clienttheight /clientWidth属性来检查更改。这是令人难以置信的缓慢和不准确，因为它会导致布局抖动。

披露:我与这个库直接相关。
