Ok to answer this   I simply converted my  lt  and the  gt  to  amp lt  and  amp gt   What was happening previously is i used to set the text  lt script gt alert  1   lt  script gt  but before setting the text in the input text browserconverts  amp lt  and  amp gt  as  lt  and the  gt   So hence converting them again to  amp lt  and  amp gt since browser will understand that as only tags and converts them   than executing the script inside  lt input type  text    gt

I usually do it element value   lt script gt alert  test    lt  script gt      If sounds like you are generating an inline  lt script gt  element  in which case the  lt  script gt  will end the HTML element and cause the script to terminate in the middle of the string   Escape the   so that it isn t treated as an end tag by the HTML parser   element value     lt script gt alert  test    lt   script gt
