From now on, I will explain to you the first section of the jQuery EasyUI tutorial-Layout: jQuery-panel (panel) component. The usage of this component is almost the same as the components in the previous articles. , the case is also implemented by setting some panel properties, events and methods triggered by the operation panel. We can learn from these three points. <br/>

Use $.fn.panel.defaults to override the default value object.

Panels serve as containers for other content. This is the basis for building other components (such as layout, tabs, accordion, etc.). It also provides collapse, close, maximize, minimize and custom behaviors. Panels can be easily embedded anywhere on a web page.

jQuery EasyUI Tutorial-Panel (Panel)

Use case:

Creating a panel

In front-end development work, panels are created through two methods: tags and programs.

1. Create panel through tags

Creating through tags is easier. Add 'easyui-panel' class ID to

tag. 

<p id=”p” class=”easyui-panel” title=”My Panel”
style=”width:500px;height:150px;padding:10px;background:#fafafa;”
data-options=”iconCls:’icon-save’,closable:true,
collapsible:true,minimizable:true,maximizable:true”>
<p>panel content.</p>
<p>panel content.</p>
</p>

2. Create the panel program

Let us create the toolbar in the upper right corner of the panel. 

<p id=”p” style=”padding:10px;”>
<p>panel content.</p>
<p>panel content.</p>
</p>
$(‘#p’).panel({
width:500,
height:150,
title: ‘My Panel’,
tools: [{
iconCls:’icon-add’,
handler:function(){alert(‘new’)}
},{
iconCls:’icon-save’,
handler:function(){alert(‘save’)}
}]
});
Copy after login

Move panel

Call the 'move' method to move the panel to a new location. 

$(‘#p’).panel(‘move’,{
left:100,
top:100
});
Copy after login

Read content

When the loading is successful, let us load the panel content through ajax and display some messages. 

$(‘#p’).panel({
href:’content_url.php’,
onLoad:function(){
alert(‘loaded successfully’);
}
});
Copy after login

当设置为true的时候面板大小将自适应父容器。下面的例子显示了一个面板；可以自动在父容器的最大范围内调整大小。

data-options="fit:true,border:false">
