当高度为auto时，jQuery OuterHeight / Height返回错误的高度值

Question

当CSS高度设置为自动时，如何获取填充文本的div对象的完整高度？

我尝试过OuterHeight，它仍然不是div对象的全高。

JSFiddle：https://jsfiddle.net/zerolfc/jg8s5oq3/3/

jQuery的：

$('div').find('*').each(function(ti,tv){
var c = parseInt( $(tv).css('font-size') ) / 2;
c = Math.floor( c );
c = ( c < 8 ? 8 : c );
$(tv).css('font-size', c + 'px');
});

console.log($('div').outerHeight(true));

CSS：

div { display: block; width: 640px; height: auto; }
p { font-size: 24px; }

HTML：

<div>
<p>This is a textbox that you can add text to suit your design and alter.This is a textbox that you can add text to suit your design and alter.</p>
<p>This is a textbox that you can add text to suit your design and alter.This is a textbox that you can add text to suit your design and alter.</p>
<p>This is a textbox that you can add text to suit your design and alter.This is a textbox that you can add text to suit your design and alter.</p>

</div>

为我提供小提琴中的正确值。

来自http://api.jquery.com/outerheight/

$('div').outerHeight(true) = [height of the $('div') + margin of $('div')]

但是根据您当前的css规则，您的$('div')元素没有任何边距。

这意味着， $('div').outerHeight(true)将返回$('div')的实际高度，没有任何边距。

在您的情况下，所有后续3的值将是相同的。

• $('div').outerHeight(true)
• $('div').outerHeight()
• $('div').css('height')
