Textbox

Employment/Purpose

A textbox is used to let users input textual data.

You colud assign value, type, constraint, rows, cols to a textbox using the corresponding properties. When you assign the property type to a string value "password" when multiline is false (multiline will be true if you set rows larger than 1 or set multiline to true directly) then any character in this component will replace by '*'.

You could also assign a constraint value with a regular expression string or a default constraint expression (available value is "no empty"). When user change the value of textbox, it will cause a validating process to validate the value. If the validation fails, then a notification will pop up.

Example

ZKCompRef Textbox.png

<textbox value="text..." />
<textbox value="secret" type="password" />
<textbox constraint="/.+@.+\.[a-z]+/: Please enter an e-mail address" />
<textbox rows="5" cols="40">
	<attribute name="value">
text line1... 
text line2...
	</attribute>
</textbox>

To specify multilines value, you can use the attribute element or &#x0d; as shown below

<textbox rows="5" cols="40">
	<attribute name="value">
text line1... 
text line2...
	</attribute>
</textbox>
<textbox value="Line 1&#x0d;Line 2" rows="3"/>

By specifying a true, the tabbox can insert a long space or format the content inside textbox conveniently. For example,

ZKComRef Textbox Tabbable.png

<textbox tabbable="true"/>
