问题描述
我正在尝试找一个忽略重音的字符串，所以在我的例子中如果我搜索avião或 aviao 我得到的两者都是结果。
这是一个启动...
I'm trying to find a string ignoring accent, so in my example if I search for avião or aviao I get both result always. here's a start up...
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript" src="http://jquery.com/src/jquery-latest.js"></script>
<script type="text/javascript">
$(function () {
$('input').keyup(function (event) {
if (jQuery.trim($('input').val()) == "") {
return;
}
var str = jQuery.trim($('input').val()).split(" ");
jQuery.each($('table > tbody > tr > td:last-child'), function () {
var colval = $(this).html().toLowerCase();
jQuery.each(str, function () {
var term = this.toLowerCase();
if (colval.indexOf(term) != -1) {
alert(colval);
}
});
});
});
});
</script>
</head>
<body>
<input type="text" id="q" />
<div>
<table>
<thead>
<tr>
<th>Id</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>avião resume</td>
</tr>
<tr>
<td>2</td>
<td>résumé</td>
</tr>
<tr>
<td>3</td>
<td>resume</td>
</tr>
<tr>
<td>4</td>
<td>aviao résumé</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
推荐答案
为了它的价值，有一次我建立了这个Latin-1 unicode的映射代码点指向其ascii对应物。
For what it's worth, at one point I had build this mapping of Latin-1 unicode codepoints to their ascii counterparts.
您可以将其用作：
var effectiveCharCode = CODE_NO_DIACRITICS[actualCharCode];
所以，一个字符串比较方法，其中< 0（s1< s2），0（s1 = = s2），> 0（s1> s2）可能类似于：
So, a string comparison method where <0 (s1 < s2), 0 (s1 == s2), >0 (s1 > s2) might be like:
function compareIgnoringDiacritics(s1, s2) {
for(var i = 0; i < s1.length && i < s2.length; i++){
var cmp;
if((cmp = ((CODE_NO_DIACRITICS[s1.charCodeAt(i)] - CODE_NO_DIACRITICS[s2.charCodeAt(i)]))) != 0){
return cmp;
}
}
return s1.length - s2.length;
}
这是表格：
var CODE_NO_DIACRITICS = [
0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
