我有一个页面，我已经放了三个标签。单击每个选项卡后，相关文本将更改。我想为每个选项卡放置三个图像，因此当用户单击选项卡时，图像应该更改。 分享主题链接：

以下是每次点击时标签在标签上的更改方式。共享JS
//交换标题
jQuery(document).on('click','.current-directory',function(){
jQuery(this).parents('ul').find('li').removeClass('active');
jQuery(this).addClass('active');
var dir_name = jQuery(this).data('dir_name');
var id = jQuery(this).data('id');
jQuery(this).parents('.tg-banner-content').find('em.current_directory').html(dir_name);
if( Z_Editor.elements[id] ) {
var load_subcategories = wp.template( 'load-subcategories' );
var data = [];
data['childrens'] = Z_Editor.elements[id];
data['parent'] = dir_name;
var _options = load_subcategories(data);
jQuery( '.subcats' ).html(_options);
}
});
//Prepare Subcatgories
jQuery(document).on('change','.directory_type', function (event) {
var id = jQuery('option:selected', this).attr('id');
var dir_name = jQuery(this).find(':selected').data('dir_name');
if( jQuery( '.dynamic-title' ).length ){
jQuery( '.dynamic-title' ).html(dir_name);
}
if( Z_Editor.elements[id] ) {
var load_subcategories = wp.template( 'load-subcategories' );
var data = [];
data['childrens'] = Z_Editor.elements[id];
data['parent'] = dir_name;
var _options = load_subcategories(data);
jQuery( '.subcats' ).html(_options);
}
});
这是我尝试修改的CSS，但我只能将一个图像添加到背景中，这是静态的。我想添加3个应随文本更改的图像。 这是CSS
.tg-homebanner{position: relative;}
.tg-homebanner figure{
width: 100%;
float: left;
margin: 0;
z-index: 1;
position: relative;
}
.tg-homebanner figure img{
display: block;
width: 100%;
/*min-height: 650px;*/
}
.tg-banner-content{
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
z-index: 2;
background: rgba(0, 0, 0, 0.9);
}
/*Here I've made changes and successfully added a background image, but the problem is I want to put 3 images that should be changed with each click*/
.tg-banner-content .form-searchdoctors .tg-btn{color: #fff;}
.tg-homebanner .tg-searchform .tg-btn{color: #fff;}
.tg-homebanner .tg-location-map{height: 800px;}
.tg-mapbox .tg-location-map{
height: 100%;
position: absolute;
}
.show-search{
position: absolute;
height: 100%;
width: 70px;
right: 0;
top: 0;
background: rgba(0, 0, 0, 0.5);
color: #fff;
font-size: 24px;
text-align: center;
display: none;
cursor: pointer;
}
.show-search i{
position: relative;
top: 50%;
}
以下是我所做出的改变：
.tg-banner-content{
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
z-index: 2;
background: url('URL OF MY IMAGE') center center no-repeat;
background-size: cover;
content: '';
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-image:linear-gradient(to bottom right,#002f4b,#dc20000);
opacity: 1;
}
但它只会使单个背景图像随点击而变化。

这是一个简单的按钮单击事件，可以使用jScript更改背景图像。这是一个示例代码
<script>
function functionName() {
document.body.style.background = "#000000 url('img.png') no-repeat right top";
}
</script>
