获取不带滚动条宽度的 Div 宽度

Question

我在这里遇到了问题。这里有两个div“div1”和“div2”。这里我想根据“div2”的宽度来调整“div1”的宽度。我的要求是“div1”不应包含滚动条的宽度，即我应该设置“div1”的高度 不包括“div2”中滚动条的宽度。我想要一个 jquery 函数来查找宽度并减小“div1”的宽度.. 样品要求如下所示

html

<div class="div1"></div>
<div class="div2">HelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHello</div>

css

.div1
{
    width:100px;
    height:100px;
    border:1px solid black;
}
.div2
{
    width:100px;
    height:300px;
    border:1px solid black;
    overflow:auto;
    word-break:break-all;
}
