still bug

zero bug

OK

let key = `ali`.toLocaleUpperCase(); // let name = "阿里云計算有限公司 alibaba"; let name = "AliOS"const getHighlightOthers = (names = ``, type = `prefix`) => {let name = names;let result = ``;let prefix = 0;let suffix = 0;if (name && name.length) {if (type === `prefix`) {prefix = name.toLocaleUpperCase().indexOf(key);if(prefix >= 0) {result = name.substr(0, prefix);}} else {suffix = name.toLocaleUpperCase().indexOf(key);if(suffix >= 0) {result = name.substr(suffix + key.length);} else {result = name;}}}console.log(`result =`, result, type);return result; }; const getHighlightKeyword = (name = ``) => {// nulllet result = ``;let prefix = 0;if (name && name.length) {prefix = name.toLocaleUpperCase().indexOf(key);if(prefix >= 0) {result = name.substr(prefix, key.length);}}console.log(`result =`, result);return result; };getHighlightOthers(name, `prefix`); getHighlightKeyword(name); getHighlightOthers(name, `suffix`);
