Usage:
(1) display layer:

The Code is as follows:

Function show ()
{
$. LayerSetup ({
Id: "abc", // the ID of the pop-up layer
Title: "test", // title
Content: 'test', // content
Isbg: false, // whether to display the background shadow Layer
Opacity: 0.3, // the transparency of the background shadow layer. The greater the value, the lower the transparency. 0 indicates completely transparent, and 1 indicates opacity.
Templete :'

'// Template
});
$. Layershow ();
}

(2) Close the layer:

The Code is as follows:

$. Layerclose ("pop-up layer ID ");

NOTE: If your template has a CSS file, you need to directly introduce it to this page. This simplified version cannot be displayed on other frameworks, so there is no such cssurl attribute and no target attribute.
