获取没有在 css 中设置高度的 div 的高度

如果没有对元素设置 CSS 高度规则,有没有办法获得元素的高度? 我不能使用 .height() jQuery 方法,因为它首先需要一个 CSS 规则集?还有别的办法测高度吗?

jQuery .height will return you the height of the element. It doesn't need CSS definition as it determines the computed height.

DEMO

You can use .height(), .innerHeight() or outerHeight() based on what you need.

enter image description here

.height() - returns the height of element excludes padding, border and margin.

.innerHeight() - returns the height of element includes padding but excludes border and margin.

.outerHeight() - returns the height of the div including border but excludes margin.

.outerHeight(true) - returns the height of the div including margin.

Check below code snippet for live demo. :)

$(function() {
var $heightTest = $('#heightTest');
$heightTest.html('Div style set as "height: 180px; padding: 10px; margin: 10px; border: 2px solid blue;"')
.append('<p>Height (.height() returns) : ' + $heightTest.height() + ' [Just Height]</p>')
.append('<p>Inner Height (.innerHeight() returns): ' + $heightTest.innerHeight() + ' [Height + Padding (without border)]</p>')
.append('<p>Outer Height (.outerHeight() returns): ' + $heightTest.outerHeight() + ' [Height + Padding + Border]</p>')
.append('<p>Outer Height (.outerHeight(true) returns): ' + $heightTest.outerHeight(true) + ' [Height + Padding + Border + Margin]</p>')
});
div { font-size: 0.9em; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="heightTest" style="height: 150px; padding: 10px; margin: 10px; border: 2px solid blue; overflow: hidden; ">
</div>

Just a note in case others have the same problem.

I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().

var currentHeight = 0;
$(window).load(function() {
//get the natural page height -set it in variable above.


currentHeight = $('#js_content_container').outerHeight();


console.log("set current height on load = " + currentHeight)
console.log("content height function (should be 374)  = " + contentHeight());


});

Also make sure the div is currently appended to the DOM and visible.

Can do this in jQuery. Try all options .height(), .innerHeight() or .outerHeight().

$('document').ready(function() {
$('#right_div').css({'height': $('#left_div').innerHeight()});
});
