public class Span

extends LabelBase

Generates styled text span based on an expression or literal value.

If the resulting value to be output is the " " String, it will output as the value " ".

Serialized Form

Example

In this first sample, a <netui:span> tag displays the Form Bean's firstName property. The <netui:span> tag will resolve this data binding expression, and display its value.

    <netui:span value="${actionForm.firstName}" />

In this next sample, the value attribute will resolve to null. This causes the defaultValue to be displayed. The user will see ' '.

    <netui:span value="${pageFlow.somethingNull}" defaultValue="&nbsp;"/>

In this next sample, the HTML will contain the text "&nbsp;" and the user will see ' '

    <netui:span value="${pageFlow.somethingNull}" defaultValue="&amp;nbsp;"/>
