Jquery.css not applying Background-Image

Question

I have some Javascript which fires after an Ajax post.

When the javascript fires I want the <section class="section-1653"> to be given a different background image to the one specified in the CSS file.

I am running the following code and I can see the Font Size being set, but the background image is not.

Why is the background image property not being set?

$("section.section-1653").css({"background-image": backgroundImageUrl,font-size": "200%"});

Answer 1

图片必须在url（）之内

$("section.section-1653").css({"background-image": "url("+backgroundImageUrl+")", "font-size": "200%"});

Answer 2

需要将其设置为：

$("section.section-1653").css({"background-image", "url('+ imageUrl +'), "font-size": "200%"});
