Question

我想用其他字符替换用户输入中的特殊字符。

当前，我有以下不起作用的内容。任何帮助将不胜感激。

$(document).ready(function(){ 
        $("#text_box_id").change(function () {
            /*var name = $(this).val();
            var dname_without_space = $("#text_box_id").val().replace(/ /g, "");*/

            var specialCharList = ["Á","É","Í","Ó","Ú","á","é","í","ó","ú","ñ","Ñ"];
            var replaceChar = ["A","E","I","O","U","a","e","i","o","u","n","N"];

            var inputUser = $("#text_box_id").val();
            var splitInput = inputUser.split(" ");
            console.log(splitInput);

            for(var i = 0; i < inputUser.length; i++){
                for(var x = 0; x < specialCharList.length; x++){
                    if(splitInput[i] == specialCharList[x]){
                        splitInput[i] = replaceChar[x];
                    }
                }
            }

            var modInputUser = splitInput.join(" ");
            console.log(modInputUser);

            /*var name_without_special_char = $("#text_box_id").val().replace(/[^a-zA-Z 0-9]+/g, ""); 
            $(this).val(name_without_special_char);
            console.log(name_without_special_char)*/
        });
    });

Answer 1

您可以分割字符串（就像您已经在做但是没有空格一样），然后通过在特殊字符列表中找到map在每个字符上运行index。如果索引存在（返回值大于-1），则可以使用该索引从替换字符列表中获取值。

然后看起来像这样：

$(document).ready(function() {
  $("#text_box_id").change(function() {

    let specialCharList = ["Á", "É", "Í", "Ó", "Ú", "á", "é", "í", "ó", "ú", "ñ", "Ñ"];
    let replaceChar     = ["A", "E", "I", "O", "U", "a", "e", "i", "o", "u", "n", "N"];

    let inputUser = $("#text_box_id").val();

    let newString = inputUser.split('').map(i => {
      let idx = specialCharList.indexOf(i)
      return idx > -1 ? replaceChar[idx] : i
    }).join('')

    $("#text_box_id").val(newString)
  });
});

<input type="text" id="text_box_id">

不要被空格分开

$(document).ready(function(){ 
    $("#text_box_id").change(function () {
        /*var name = $(this).val();
        var dname_without_space = $("#text_box_id").val().replace(/ /g, "");*/

        var specialCharList = ["Á","É","Í","Ó","Ú","á","é","í","ó","ú","ñ","Ñ"];
        var replaceChar = ["A","E","I","O","U","a","e","i","o","u","n","N"];

        var inputUser = $("#text_box_id").val();
        var splitInput = inputUser.split("");
        console.log(splitInput);

        for(var i = 0; i < inputUser.length; i++){
            for(var x = 0; x < specialCharList.length; x++){
                if(splitInput[i] == specialCharList[x]){
                    splitInput[i] = replaceChar[x];
                }
            }
        }

        var modInputUser = splitInput.join("");
        console.log(modInputUser);

        /*var name_without_special_char = $("#text_box_id").val().replace(/[^a-zA-Z 0-9]+/g, ""); 
        $(this).val(name_without_special_char);
        console.log(name_without_special_char)*/
    });
});

这意味着分割每个字符：

var splitInput = inputUser.split("");

您可以尝试以下方法：

  function cleanString(str) {
     str = str.toLowerCase().replace(" ", "_");
     str = str.replace(/[äâàáã]/g, "a").replace(/[ëêèéẽ]/g, "e").replace(/[ïîìíĩ]/g, "i");
     str = str.replace(/[öôòóõ]/g, "o").replace(/[üûùúũ]/g, "u");
     str = str.replace(/ç/g, "c").replace(/[^a-z0-9]/g, "");
     return str;
  }

测试

cleanString("áéíóú") // returns "aeiou"

替换字符串数组中的一个或多个字符
