替换字符串以及转换为数组

 

  <script>
    // 替换字符串 replace('被替换的字符','替换为的字符')  它只会替换掉第一个字符
    var str = "andyandy ";
    console.log(str.replace("a, b")); //把a替换掉换成b
    // 有一个字符串'abcoefoxyozzopp'要求把里面所有o替换为*
    var str1 = "abcoefoxyozzopp";
    while (str1.indexOf("o") !== -1) {
      str1 = str1.replace("o", "*");
    }
    console.log(str1);

    // 字符转换为数组 split('分隔符')
    let num = "pink blue red";
    console.log(num.split(","));
    let num1 = "pink&blue&red";
    console.log(num1.split("&"));
  </script>
