     <doublespinner step="0.5" />

In-place Editing

Fixed Width

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



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

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

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

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


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 doublespinner.

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

<doublespinner step="0.5" constraint="no empty,min -2.5 max 6.5"/>

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

<doublespinner step="0.5" constraint="no empty,min -2.5 max 6.5: between -2.5 to 6.5"/>


  • 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.
<doublespinner step="0.5" constraint="no empty,min -2.5 max 6.5: ${c:l('err.msg.doublespinner')}"/>
