Building Text Entry Boxes
|
|
|
|
The CFTEXTINPUT tag is a very close relative to the HTML INPUT=text tag. With CFTEXTINPUT, however, you can also specify font and alignment options, as well as enable one of two input validation methods using either a JavaScript or the VALIDATE attribute in CFTEXTINPUT.

|
Example: CFTEXTINPUT control
|
|
|
The following example shows a basic CFTEXTINPUT control. This example validates a date entry, which means that a user must enter a valid date in the form mm/dd/yy.
<BR>Please enter a date:
<CFFORM NAME="Form1" ACTION="cfform_submit.cfm" METHOD="Post">
<CFTEXTINPUT NAME="entertext"
VALUE="mm/dd/yy"
MAXLENGTH="10"
VALIDATE="date"
FONT="Trebuchet MS">
<BR><INPUT TYPE="Submit"
VALUE="Submit">
</CFFORM>
The CFTEXTINPUT looks like this:
|
|
|
|
CFTEXTINPUT form variable |
|
|
|
The value of the form variable passed from a CFTEXTINPUT control to a ColdFusion application page is determined by the entry in the CFTEXTINPUT control. The form variable is passed as:
textinput_name=textinput_value
In the example just above, the form variable would have been passed as:
entertext=textinput_value
So in the destination application page, the form variable is referenced as #entertext#.
