この簡略化されたバージョンでは、他のフレームでレイヤーをポップアップすることができないため、cssurl 属性と target 属性はありません。
コードをコピーします コードは次のとおりです:

使用法:
(1) 表示レイヤー:
コードは次のとおりです:
function show() { $.layerSetup({ id:"abc",//弹出层的ID title:"test",//标题 content:'test',//内容 isbg:false,//是否显示背景遮照层 opacity:0.3,//背景遮照层的透明度,值越大透明度越低,0为完全透明,1为不透明 templete:'<p 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></p><p class="showwint_mini_content"><p class="showwint_mini_content_content" id="@contentid@"></p> </p>'//模板 }); $.layershow(); }
( 2 ) レイヤーを閉じます:
コードをコピーします コードは次のとおりです:
$.layerclose("弹出层的ID");
注: テンプレートに CSS がある場合この簡易バージョンは他のフレームにポップアップ表示できないため、cssurl 属性や target 属性はありません。
