Title Body

there are some similar questions out there, but none that are quite the same or that have an answer that works for me. I need a javascript function which validates whether a text field contains all valid latin characters, so no cryllic or Chinese, just latin; specifically: Basic Latin (excluding the C0 control characters), Latin-1 (excluding the C1 control characters), Latin Extended A, Latin Extended B and Latin Extended Additional. This set corresponds to Unicode code points U+0020 to U+007E, U+00A0 to U+024F and U+IE00 to U+IEFF Some of the answers out there seem to check the first character in the text field but miss out others, so these are no good. This is what I have tried so far (this doesn't work!): var value = 'abcdef' // from text field var re = '\u0000-\u007F|\u0100-\u017F|\u0180-\u024F|\u1E00-\u1EFF|\u0080-\u00FF'; // latin regexp string // var re = '\\w+/'; // alternative if (new RegExp(re).test(value)) { result = false; } The following sort of works but only for the first character: //var re = '\u0000-\u007F|\u0100-\u017F|\u0180-\u024F|\u1E00-\u1EFF|\u0080-\u00FF'; // latin regexp string // couldn't get the above to work so using the following: var re = '\\w+'; if (!value.match(re)) { message = 'Please enter valid latin characters only'; $focusField = $this; } What is the right way to do this? I really need code, rather than an explaination, but both would be better. Thanks
