使用方法:
$.layerSetup({ id:"弹出层的ID", title:'弹出层的标题文字', target:在哪个目标柜架弹出层如window.parent,默认为window.self, cssurl:'弹出层的CSS样式文件的地址', content:'弹出的内容', isbg:是否显示一个遮照层, templete:'为层设置布局模板如:<div class="showwint_mini_title"><span class="showwint_mini_close_btn"><a href="javascript:void(null);" class="layerclose"></a></span><span class="showwint_mini_title_content" id="@moveid@"><span id="@titleid@"></span></span></div><div class="showwint_mini_content"><div class="showwint_mini_content_content" id="@contentid@"></div></div>', opacity:设置遮照层的透明度, width:宽, height:高 }); $.layershow();
其中布局模板中的"@titleid@"、"@moveid@"、"@contentid@"、"@width@"、"@height@"为模板中放置标题ID、拖动ID、内容ID、宽、高等,可以根据你自己设计的模板不同放在不同的位置.
