Get height of div with no height set in css

Question

Is there any way to get the height of an element if there is no CSS height rule set for the element I cannot use .height() jQuery method because it need a CSS rule set first? Is there any other way to get the height?

Answer 1

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.

.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; }
