Description

The TextBox control is used to display a single line input area.

While a variety of different events are available, the usual response to editing a TextBox is to call the function <buttonID>_onblur().

To add a TextBox to your app, choose the TextBox icon in the Toolbar, then position it on the Design Screen. Use the Property Editor to set the properties you need. If necessary, add functions to your code to respond to the events that come from the TextBox: usually, just on blur.

To get rid of the white text shadowing when displaying on coloured backgrounds, put text-shadow: none; in the control's style property.

If you would like to do masked input, use this: http://digitalbush.com/projects/masked-input-plugin/. Do not use it with input types such as Date and Time, which already have special formatting.

Properties

Standard properties are supported, plus:

autocapitalize Automatically capitalize first letter? May not be available on other platforms.
autocomplete Automatically complete words? May not be available on other platforms.
autocorrect Spellcheck as entering? May not be available on other platforms.
inputType Specifies what kind of data will be input. Choices are color, date, datetime, email, file (iOS 6+ and Android 4+ only), hidden, month, number, password, range, search, tel, text, time and url. Default is text.
placeholder Text to be displayed in the field just as a comment – does not change the value.
readonly If set to “True”, the control cannot be edited. At runtime, use readOnly.
size Maximum characters allowed.
text The contents of the TextBox. Same as value.
value The contents of the TextBox. This is always returned as a string. Convert it to a number before doing arithmetic on it – see “Conversions”.

Events

Standard events are supported, plus:

onblur Called when exiting the field.
onkeypress Called when a key is pressed.

Example (Basic)

Rem TextBox Example
Function Text1_onblur()
  Msgbox Text1.value
End Function

Example (JavaScript)

// TextBox Example

Text1.onblur = function() {
  alert(Text1.value);
}

Setting a jQuery Mobile TextBox to Transparent

TextBox1_wrapper.children[0].style.backgroundColor = "transparent" 

Getting KeyDown events in a jQuery Mobile TextBox Search

Since the Search button has some extra styling, it gets recreated after the app is loaded and before Sub Main() is run. This wipes out the definition you made of TextBox1_onkeypress.

Here's the workaround:

Sub Main()
  JavaScript
  // Create a call to mykeydown on when key pressed, after Search button is created.
  $("#TextBox1").keydown(function(){onmykeydown()})
  End JavaScript
End Sub

Function onmykeydown()
  console.log("keydown")
End Function
