+</span></span> * @class Ext.form.field.Text
+ * @extends Ext.form.field.Base
+
+A basic text field. Can be used as a direct replacement for traditional text inputs,
+or as the base class for more sophisticated input controls (like {@link Ext.form.field.TextArea}
+and {@link Ext.form.field.ComboBox}). Has support for empty-field placeholder values (see {@link #emptyText}).
+
+#Validation#
+
+The Text field has a useful set of validations built in:
+
+- {@link #allowBlank} for making the field required
+- {@link #minLength} for requiring a minimum value length
+- {@link #maxLength} for setting a maximum value length (with {@link #enforceMaxLength} to add it
+ as the `maxlength` attribute on the input element)
+- {@link regex} to specify a custom regular expression for validation
+
+In addition, custom validations may be added:
+
+- {@link #vtype} specifies a virtual type implementation from {@link Ext.form.field.VTypes} which can contain
+ custom validation logic
+- {@link #validator} allows a custom arbitrary function to be called during validation
+
+The details around how and when each of these validation options get used are described in the
+documentation for {@link #getErrors}.
+
+By default, the field value is checked for validity immediately while the user is typing in the
+field. This can be controlled with the {@link #validateOnChange}, {@link #checkChangeEvents}, and
+{@link #checkChangeBugger} configurations. Also see the details on Form Validation in the
+{@link Ext.form.Panel} class documentation.
+
+#Masking and Character Stripping#
+
+Text fields can be configured with custom regular expressions to be applied to entered values before
+validation: see {@link #maskRe} and {@link #stripCharsRe} for details.

+
+ A validator offers a way to customize and reuse a validation specification.
+ If a field is configured with a `{@link #validator}`
+ function, it will be passed the current field value. The `{@link #validator}`
+ function is expected to return either:
+
+ - Boolean `true` if the value is valid (validation continues).
+ - a String to represent the invalid message if invalid (validation halts).
+
+2. **Basic Validation**
+
+ If the `{@link #validator}` has not halted validation,
+ basic validation proceeds as follows:
+
+ - `{@link #allowBlank}` : (Invalid message = `{@link #emptyText}`)
+
+ Depending on the configuration of <code>{@link #allowBlank}</code>, a
+ blank field will cause validation to halt at this step and return
+ Boolean true or false accordingly.
+
+ - `{@link #minLength}` : (Invalid message = `{@link #minLengthText}`)
+
+ If the passed value does not satisfy the `{@link #minLength}`
+ specified, validation halts.
+
+ - `{@link #maxLength}` : (Invalid message = `{@link #maxLengthText}`)
+
+ If the passed value does not satisfy the `{@link #maxLength}`
+ specified, validation halts.
+
+3. **Preconfigured Validation Types (VTypes)**
+
+ If none of the prior validation steps halts validation, a field
+ configured with a `{@link #vtype}` will utilize the
+ corresponding {@link Ext.form.field.VTypes VTypes} validation function.
+ If invalid, either the field's `{@link #vtypeText}` or
+ the VTypes vtype Text property will be used for the invalid message.
+ Keystrokes on the field will be filtered according to the VTypes
+ vtype Mask property.
+
+4. **Field specific regex test**
+
+ If none of the prior validation steps halts validation, a field's
+ configured <code>{@link #regex}</code> test will be processed.
+ The invalid message for this test is configured with `{@link #regexText}`
