JS array sort strings case insensitive To compare strings in a case insensitive manner, we call thetoLowerCasefunction on the compared elements. main.js let words = ["world", "War", "abbot", "Caesar", "castle", "sky", "den", "forest", "ocean", "water", "falcon", "owl", "rain...
If you want a case-insensitive search, you can write if (str.toLowerCase().indexOf("abcd") >= 0) Or, if (/abcd/i.test(str)) And a general version for a case-insensitive search, you can set strings of any case if (stringA.toLowerCase().indexOf(stringB.toLowerCase()) >=...
为什么会这样呢?因为sort不会直接比较数字类型,而已转为string了再做的比较。那么我们想要比较数字怎办?我们可以往sort传函数,例: function mycompare(o1, o2) { return o1 - o2;//如果为正数则o1大,负数则o2大,零则相等。 } var arr2 = [5, 14, 23, 12, 1]; alert(arr2.sort(mycompare)); ...
function case_insensitive_comp(strA, strB) { return strA.toLowerCase().localeCompare(strB.toLowerCase()); } var str = 'ACBacbA'; // split the string in chunks str = str.split(""); // sorting str = str.sort(); str = str.sort( case_insensitive_comp ) // concatenate the chunks...

To also make the case insensitive while comparing the string, you may also pass sensitivity: 'base' option. This would compare the two strings value and VALUE as equal, ignoring the casings. An example using both the options is below: leftString.localeCompare(rightString, undefined, { numeric...
