javascript 获取属性值

Question

如何使用 javascript 从“style”属性获取“width”、“height”和“background-image”值？

<div id="someid" class="someclass" style="width: 100px; height: 100px; background-image: url(https://some image.jpg);">

Answer 1

您可以像这样获取属性:

// To get width
$('#someid').css('width');
// To get height
$('#someid').css('height');
// To get background-image
$('#someid').css('background-image');
