我有以下代码，它们将用户在html页面中的某些字段上输入的内容转换为阿拉伯字符：
window.onload = function KeyboardChange(){
var elements = document.querySelectorAll('.arabicChange');
for (var i = elements.length - 1; i >= 0; i--) {
elements[i].onkeydown = function myFunction(e){
var keyCode = window.event ? window.event.keyCode : e.which;
if(keyCode == 66) {
this.value += "ل";
this.value +="ا";
return false;
}
//this case is for deleting one character
if (keyCode == 8){
this.value = this.value.substr(0,length(this.value)-1);
}
if (keyCode == 9){
if (this == document.forms[0].ancienNomPropriete)
document.forms[0].nomPropriete.focus();
if (this == document.forms[0].nomPropriete)
document.forms[0].dateBornage.focus();
}
else{
var KEYS_MAP= {
32 : " ",
97 : "1",
98 : "2",
99 : "3",
100: "4",
101: "5",
102: "6",
103: "7",
104: "8",
105: "9",
65 :"ض",
90 :"ص",
69 :"ث",
82 :"ق",
84 :"ف",
89 :"غ",
85 :"ع",
73 :"ه",
79 :"خ",
80 :"ح",
221 :"ج",
81 :"ش",
83 :"س",
68 :"ي",
70 :"ب",
71 :"ل",
72 :"ا",
74 :"ت",
75 :"ن",
76 :"م",
77 :"ك",
192 :"ط",
220 :"ذ",
87 :"ئ",
88 :"ء",
67 :"ؤ",
86 :"ر",
66 :"ل",
78 :"ى",
188 :"ة",
190 :"و",
191 :"ز",
223 :"ظ",
186 : "د"
};
if(keyCode && KEYS_MAP[keyCode]){
this.value += KEYS_MAP[keyCode];
return false;
}
};
return false ;
};
};
};
我从jsp页面调用此脚本。该脚本不起作用，在Firefox中进行调试后，阿拉伯字母显示在问号中。像这样 ：
window.onload = function KeyboardChange(){
var elements = document.querySelectorAll('.arabicChange');
for (var i = elements.length - 1; i >= 0; i--) {
elements[i].onkeydown = function myFunction(e){
var keyCode = window.event ? window.event.keyCode : e.which;
if(keyCode == 66) {
this.value += "�";
this.value +="�";
return false;
}
//this case is for deleting one character
if (keyCode == 8){
this.value = this.value.substr(0,length(this.value)-1);
}
if (keyCode == 9){
if (this == document.forms[0].ancienNomPropriete)
document.forms[0].nomPropriete.focus();
if (this == document.forms[0].nomPropriete)
document.forms[0].dateBornage.focus();
}
else{
var KEYS_MAP= {
32 : " ",
97 : "1",
98 : "2",
99 : "3",
100: "4",
101: "5",
102: "6",
103: "7",
104: "8",
105: "9",
65 :"�",
90 :"�",
69 :"�",
82 :"�",
84 :"�",
89 :"�",
85 :"�",
73 :"�",
79 :"�",
80 :"�",
221 :"�",
81 :"�",
83 :"�",
68 :"�",
70 :"�",
71 :"�",
72 :"�",
74 :"�",
75 :"�",
76 :"�",
77 :"�",
192 :"�",
220 :"�",
87 :"�",
88 :"�",
67 :"�",
86 :"�",
66 :"�",
78 :"�",
188 :"�",
190 :"�",
191 :"�",
223 :"�",
186 : "�"
};
if(keyCode && KEYS_MAP[keyCode]){
this.value += KEYS_MAP[keyCode];
return false;
}
};
return false ;
};
};
};
我的jsp页面以以下代码行开头：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<link href="pages/style/main.css" rel="stylesheet" type="text/css">
<script language="JavaScript1.2" src="pages/KeyboardAutomaticChange.js"> </script>
为什么阿拉伯字符显示问号？
最佳答案
尝试在HTML中添加charset="UTF-8"
它应该看起来像这样
<script language="JavaScript1.2" src="pages/KeyboardAutomaticChange.js" charset="UTF-8"> </script>
如果失败，则您的JavaScript文件KeyboardAutomaticChange.js可能使用非utf-8编码保存。
我建议在文本编辑器中创建一个新的javascript文件，该文件已配置为以utf-8编码保存文件，然后将KeyboardAutomaticChange.js的内容复制粘贴到此文件中。
