javascript - jQuery 替换精确数字

Question

我有一些数字从 0 到 3200 的 div，想用一个字符替换它们。

html 示例:

  <div>2</div>
  <div>6</div>
  <div>26</div>

jQuery 示例:

   $('div').text(function () {
                return $(this).text().replace("1","K").replace("2","/").replace("3","@").replace("4","r").replace("5","[").replace("6","[").replace("7","[").replace("8",",").replace("9",",").replace("10","J").replace("11",",").replace("12",",").replace("13","P").replace("14","]").replace("15","]").replace("16","]").replace("17","R").replace("18","R").replace("19","N").replace("20","N").replace("21","N").replace("22","N").replace("23","W").replace("24","L").replace("25","d").replace("26","D").replace("27","(").replace("28","B").replace("29","b").replace("30","B").replace("31","a").replace("32","A").replace("33","f").replace("34","F").replace("35","[").replace("36",":").replace("37","@").replace("38","@").replace("39","!").replace("40","?").replace("41","Z").replace("42","]").replace("43","Z").replace("44","B").replace("45","@").replace("46","]").replace("47","@").replace("0","V").replace("3200","c");
            });

我得到的 2 -/正确，6 - [ 正确，以及 26 -/[ 错误 26 应该是D。

你能帮我解决我的 jQuery 代码吗？现场 jsFiddle 在这里:http://jsfiddle.net/UEy7w/

Answer 1

我建议的方法:

var charMap = {
    '1' : 'K',
    '2' : '/',
    '3' : '@',
    '4' : 'r',
    '6' : '[',
    '26' : 'D'
    // please fill in the rest yourself
};

$('div').text(function (i,t) {
    return charMap[t] || t;
});

这种方法避免了 2和6的26通过整个现有文本 t 进行单独评估元素作为 charMap 的键对象并返回相关字符，或者，如果该文本不存在该字符，则返回旧文本本身。

• “普通”JavaScript:
  • String.replace() .
• jQuery:
  • text() .
