问题描述
我有一个带有多个选项的选择框 - 这些选项中的每一个都对应于下面某些图像的值属性。我想要的功能是当selectbox值被更改时,带有相应值的img用红色边框突出显示。以下是代码:
I have a selectbox with several options - each of these option values correspond to a "value" attribute on some images below. The functionality I want is when selectbox value is changed the img with the corresponding value is highlighted with a red border. Here is the code:
function assignValue() {
selectboxvalue = $('#Box_style').val() ;
$('.tabContent img[value="+selectboxvalue+"]').css({border: '1px solid #c10000'});
}
$('#Box_style').change(assignValue);
环顾jquery文档(http://api.jquery.com/attribute-equals-选择器),显然这应该工作...
Looking around at the jquery documentation (http://api.jquery.com/attribute-equals-selector), apparently this should work...
任何帮助将不胜感激,谢谢!
Any help would be appreciated, Thank you!
推荐答案
在jQuery 1.7之前
以下内容可行:
$('.tabContent img[value='+selectboxvalue+']').css({border: '1px solid #c10000'});
jQuery 1.7及更高版本
在1.7中,jQuery将语法更改为要求属性
在值周围加上引号:
In 1.7 jQuery changed the syntax to require the attributes
to have quotation around the value:
$('.tabContent img[value="'+selectboxvalue+'"]').css({border: '1px solid #c10000'});
