一、说明
- 在Layui点击数据表中的图片或视频，弹框预览。
- Layui如下：
//第一步:编写模板。你可以用一个script如： <script id="demo" type="text/html"> <h3>{
{
d.title }}</h3> <ul> {
{
# layui.each(d.list, function(index, item){
}} <li> <span>{
{
item.modname }}</span> <span>{
{
item.alias }}：</span> <span>{
{
item.site || '' }}</span> </li> {
{
# }); }} {
{
# if(d.list.length === 0){
}} 无数据 {
{
# } }}
</ul>
</script>
//第二步：建立视图。用于呈现渲染结果。
<div id="view"></div>
//第三步：渲染模版
var data = {
//数据
"title":"Layui常用模块"
,"list":[{
"modname":"弹层","alias":"layer","site":"https://www.sojson.com/layui/layer.html"},{
"modname":"表单","alias":"form"}]
}
var getTpl = demo.innerHTML
,view = document.getElementById('view');
laytpl(getTpl).render(data, function(html){
view.innerHTML = html;
});
二、预览
1、默认效果
2、预览图片效果
- 点击图片放大，再次点击图片外任意地方关闭
- 或者设置
,closeBtn: 1 //显示关闭按钮
3、预览视频效果
- 点击视频，放大，点击关闭按钮关闭
三、代码
- 可直接运行，如果失效，引入最新的Layui线上地址
