 <window title="Spinner" border="normal" width="150px">
     <spinner />
 </window>

In-place Editing

Fixed Width

<spinner width="100px" inplace="true" value="30" />

Dynamic Width

Because inplace editing function in ZK is pure client side action, so we can use client api to modify the width (server side do not need to know)

ZK Component Reference-Input-Spinner-inplace.jpg

<zk xmlns:c="client">
  <spinner inplace="true" value="240" width="30px" c:onFocus='this.setWidth("60px")' c:onBlur='this.setWidth("30px")' />
</zk>

Properties

Format

You are able to format the field by providing specifying the attribute with a formatting string. The default value is null.

<spinner format="#,##0.##"/>
 Since 8.5.2

You can provide a locale to format the number by specify the String starts with "locale:"

<spinner format="locale:zh-TW"/>

Constraint

You could specify what value to accept for input controls by use of the constraint property. It could be a combination of no empty and the minimum and maximum to spinner.

To specify two or more constraints, use comma to separate them as follows.

<spinner constraint="no empty,min -2 max 6"/>

If you prefer to display different message to the default one, you can append the error message to the constraint with a colon.

<spinner constraint="no empty,min -2 max 6: between -2 to 6"/>

Notes:

  • The error message, if specified, must be the last element and start with colon.
  • To support multiple languages, you could use the 「l」 function as depicted in the Internationalization chapter.
<spinner constraint="no empty,min -2 max 6: ${c:l('err.msg.spinner')}"/>
