在 jQuery 中突出显示带有(和不带有)重音字符/变音符号的单词

发布于 2024-11-08 13:46:51 字数 462 浏览 4 评论 0原文

我正在使用 jquery.highlight 插件: http://code.google.com/p/gce-empire/source/browse/trunk/jquery.highlight.js?r=2

我用它来突出显示搜索结果。

问题是,如果我搜索像 “café” 这样的内容,它不会突出显示任何单词。

如果我搜索“cafe”,即使我的结果同时包含“cafe”和“cafe”。 “café”,它将仅突出显示“cafe”

因此,我需要突出显示单词的所有“版本”,无论是否带有变音符号。

这可能吗?

I'm using the jquery.highlight plugin: http://code.google.com/p/gce-empire/source/browse/trunk/jquery.highlight.js?r=2

I'm using it to highlight search results.

The problem is that if I search something like "café" it won't highlight any words.

And if I search "cafe", even though my results contains both "cafe" & "café", it will only highlight "cafe".

So, I would need to highlight all "versions" of the words, with or without diacritics.

Is that possible?

测试 HTML:

<div id="wrapper-accent-sensitive">
 <p>cafe</p>
 <p>asdf</p>
 <p>café</p>
</div>
<hr />
<div id="wrapper-not-accent-sensitive">>
 <p>cafe</p>
 <p>asdf</p>
 <p>café</p>
</div>

测试 CSS:

.yellow {
    background-color: #ffff00;
}

替换 Javascript:

jQuery.fn.highlight = function (words, options) {
    var accentedForms = {
        'c': 'ç',
        'e': 'é'
    };

    var settings = { className: 'highlight', element: 'span', caseSensitive: false, wordsOnly: false, accentInsensitive: false };
    jQuery.extend(settings, options);

    if (settings.accentInsensitive) {
        for (var s in accentedForms) {
            words = words.replace(s, '[' + s + accentedForms[s] + ']');
        }
    }

    if (words.constructor === String) {
        words = [words];
    }

    var flag = settings.caseSensitive ? "" : "i";
    var pattern = "(" + words.join("|") + ")";
    if (settings.wordsOnly) {
        pattern = "\\b" + pattern + "\\b";
    }
    var re = new RegExp(pattern, flag);

    return this.each(function () {
        jQuery.highlight(this, re, settings.element, settings.className);
    });
};

测试代码:

$(document).ready(function() {
    $("#wrapper-accent-sensitive").highlight("cafe", { className: 'yellow' });
    $("#wrapper-not-accent-sensitive").highlight("cafe", { className: 'yellow', accentInsensitive: true });
});

Test HTML:

<div id="wrapper-accent-sensitive">
 <p>cafe</p>
 <p>asdf</p>
 <p>café</p>
</div>
<hr />
<div id="wrapper-not-accent-sensitive">>
 <p>cafe</p>
 <p>asdf</p>
 <p>café</p>
</div>

Replacement Javascript:

jQuery.fn.highlight = function (words, options) {
    var accentedForms = {
        'c': 'ç',
        'e': 'é'
    };

    var settings = { className: 'highlight', element: 'span', caseSensitive: false, wordsOnly: false, accentInsensitive: false };
    jQuery.extend(settings, options);

    if (settings.accentInsensitive) {
        for (var s in accentedForms) {
            words = words.replace(s, '[' + s + accentedForms[s] + ']');
        }
    }

    if (words.constructor === String) {
        words = [words];
    }

    var flag = settings.caseSensitive ? "" : "i";
    var pattern = "(" + words.join("|") + ")";
    if (settings.wordsOnly) {
        pattern = "\\b" + pattern + "\\b";
    }
    var re = new RegExp(pattern, flag);

    return this.each(function () {
        jQuery.highlight(this, re, settings.element, settings.className);
    });
};

Test code:

$(document).ready(function() {
    $("#wrapper-accent-sensitive").highlight("cafe", { className: 'yellow' });
    $("#wrapper-not-accent-sensitive").highlight("cafe", { className: 'yellow', accentInsensitive: true });
});

我可以推荐一个开箱即用的支持此功能的优秀库:highlight.js。虽然它旨在对代码块进行语法突出显示,但您也可以通过定义相应的语言语法来突出显示其他(关键字)单词。

例如,在语言规范中设置 lexemes : '[äöüäÖÜßa-zA-Z]+' 选项将启用带有德语特殊字符的关键字。

I can recommend a good library that supports this out of the box: highlight.js. While it is designed to do syntax highlighting for code blocks, you can equally as well highlight other (key-)words by defining an according language syntax grammar.

Setting the option of lexemes : '[äöüÄÖÜßa-zA-Z]+' in your language specification will enable keywords with German special characters, for example.
