javascript - Compare 2 strings and change color -

i not sure how should go this. 2 string database comma seperated below

string1 = "dd,cc,ff" string2 = "dd,xx,ff" 

i bind string1 html table.

you can see 2 strings different. want find string2 in string 1 , highlight changed part of string.

so output string1 = dd,cc,ff

so table show whole string highlight value "cc" in table.

how should go this? open use jquery or javascript.

compare each comma seperated value, if not same, wrap tag of kind :

function checkstrings(str1, str2) {     str1 = array.isarray(str1) ? str1 : str1.split(',');     str2 = array.isarray(str2) ? str2 : str2.split(',');      (var i=0; i<str1.length; i++) {         if (str1[i] !== str2[i])              str1[i] = '<b>' + str1[i] + '</b>';     }     return str1.join(''); }

or if order doesn't matter :

function checkstrings(str1, str2) {     str1 = array.isarray(str1) ? str1 : str1.split(',');      (var i=0; i<str1.length; i++) {         if (str2.indexof(str1[i]) == -1) {             str1[i] = '<b>' + str1[i] + '</b>';         }     }     return str1.join(''); }
