06、replace(stringToBeReplaced,stringToAdd) 此方法获取字符串中出现的字符并将其替换为另一个字符。也许用户在文本字段中输入了电话号码,并且必须添加破折号而不是空格。你可以这样做: constuserInput ='414 555 5656';console.log(userInput.replace(' ','-...
add the character and a space// to the variable// If the character is a space, trim it to an empty// string, then only add it if it is truthyif(char.trim()) {result+=char+' ';
this.letterCounts = new DefaultMap(0); // Map from letters to counts this.totalLetters = 0; // How many letters in all } // This function updates the histogram with the letters of text. add(text) { // Remove whitespace from the text, and convert to upper case text = text.replace...
