How to write Java script for refering the 1st page text field from 2nd page?

[srinivas1506]

HelloI am developing an VISITOR info interactive form with webdynpro ABAP, its with 2 pages. Their heirarchy is,

VISITOR_form
    |
    |
    |------Page_1
    |            |
    |            |
    |            |------Text_Field_A_1
    |            |
    |            |------Text_Field_A_2
    |
    |------Page_2
                 |
                 |
                 |------Text_Field_B_1
                 |
                 |------Text_Field_B_2

Now, i have selected the 'Text_Field_B_1' of page_2 and writing the Java script, my requirement is; If Page_1's 'Text_Field_A_2' has a value of "Value_ABCD", THEN the 'Text_Field_B_1' of page_2 should be 'readOnly'. Pls let me know Wht is the Java script for this requirement?
