    Hi,

    Can you have a like command in javascript i.e.

    If (x like '%HelloWorld%)
    {
    then do this
    }
    else
    {
    do this
    }

    I can't find it anywhere

    All i can find is == , != , === and the <> but not like.

    Please help

    != would be the same as <>

    Google for regular expressions. Javascript implements regular expressions for pattern matching. The Like operator is an SQL operator.

    Or you could lever whatever is java's standard does_string_contain_this_string( string1 , string2 ) function to do it - strstr() or whatever for a quick and dirty fix.

    Something like the following should work:
    if( x && x.substring( 'HelloWorld' ) > -1 ) {
  // then do this
}
else {
  // do this
}
