Convert kanji to katakana jquery javascript

Kanji and Katakana are two different writing systems. Chinese characters are an important part of Chinese culture, while Katakana is derived from the Japanese writing system. In the process of learning and communicating in Japanese, the conversion of kanji and katakana is very common. This article will introduce how to use jQuery and JavaScript to implement the Kanji to Katakana function.

1. Introduction to Katakana

Katakana, also known as hiragana, is a basic syllabic character in Japanese. Unlike the pictographic and symbolic nature of kanji, katakana is a kana (i.e. musical note) type script, consisting of 46 basic characters. They are characterized by smooth and natural curves and are generally used to represent particles, pronunciations of words, etc. in Japanese.

Take "こんにちは" (meaning "Hello") as an example. Its Chinese character is "Hello", and the pronunciation of this word in Japanese is "konnichiwa", where "konnichi" means "today" ", "wa" is a modal particle suffix. Therefore, Japanese language learners need to master the conversion between kanji and katakana.

2. Convert Kanji to Katakana

1. Determine the conversion method

Before converting Kanji to Katakana, we need to determine the conversion method. There are usually two conversion methods: one is conversion based on a rule table, that is, converting Chinese characters into corresponding katakana through a preset rule table; second, conversion based on API interface, that is, conversion is achieved by calling the katakana conversion API interface.

This article will take the conversion method based on the rule table as an example to show how to use jQuery and JavaScript to implement the function of converting kanji to katakana.

2. Write the conversion code

First, you need to write a rule table, and perform the conversion operation from kanji to katakana based on the contents in the rule table. Here is a simple rule table example:

var conversionRules = {
'あ': 'a',
'い': 'i',
'う': 'u ',
'え': 'e',
'お': 'o',
'か': 'ka',
'き': 'ki',
'く': 'ku',
'け': 'ke',
'こ': 'ko',
// Other rules...
};

Next, we can write the relevant JavaScript code to convert kanji to katakana:

function convertKana(text) {
var conversionRules = {

// 规则表...

};
var kanaText = '';
for (var i = 0; i < text.length; i ) {

var char = text[i];
var isKanji = /[一-龠]/.test(char);
if (isKanji) {
  // 如果是汉字，则根据规则表转换为片假名
  var kana = conversionRules[char];
  if (kana) {
    kanaText += kana;
  }
} else {
  // 如果是已经是片假名，则直接添加
  kanaText += char;
}

}
return kanaText;
};

This code first defines a rule table variable conversionRules, and then defines a convertKana function to implement the function of converting Chinese characters into katakana. The parameter of the function is the Chinese character text to be converted, and the function will perform the conversion operation based on the content in the rule table.

The implementation idea of ​​this function is to first determine whether a character is a Chinese character. If it is a Chinese character, it will be converted according to the rule table. Otherwise, it will be directly added to the text that outputs katakana.

3. Use in the page

Finally, we can call this conversion function in the page to realize the function of converting kanji to katakana.

For example, add the following code in the HTML file:

Then, add the following JavaScript code at the bottom of the page:

$(function () {
$('#convert').click(function() {

var input = $('#input').val();
var output = convertKana(input);
$('#output').html(output);

Copy after login

});
});

In this code, the jQuery selector is used The text box and button elements in the page are selected, and the conversion operation is triggered through the click event. The result of the conversion is output to a div tag. Users only need to enter Chinese characters and click the "Convert" button to see the conversion results immediately.

3. Summary

Through the introduction of this article, we have learned how to use jQuery and JavaScript to realize the function of converting kanji to katakana. Developers can choose different conversion methods and tool libraries based on specific project needs to complete various kanji to katakana applications. Although katakana is not the original Japanese, it is an important part of Japanese characters and plays an important role in Japanese learning and communication.
