java - 检查 tpl-if-tag，gxt 模板中的字符是否为中文

Question

在我的 java gxt-项目中，我有一个模板，其中有以下 tpl 标记，这些标记根据父标题决定标题是否必须为斜体。

                <tpl if="titleORG != &quot;&quot;">
                <tpl if="ParentTitleORG == &quot;&quot;"><i></tpl>
                <b>{titleORG}<tpl if="subtitleORG != &quot;&quot;">: {subtitleORG}</tpl></b>
                <tpl if="ParentTitleORG == &quot;&quot;"></i></tpl>
                </tpl>
                <tpl if="titleEN != &quot;&quot;">
                    <tpl if="officialTitleTranslation"> / {titleEN}<tpl if="subtitleEN != &quot;&quot;">: {subtitleEN}</tpl></tpl>
                </tpl>.

最近我收到一个票，如果不是中文或韩文，是否可以只将标题设为斜体。

知道吗，我该如何检查？

谢谢

您必须在传递到 XTemplate 的类中检查它。

添加一个 boolean 值(我将其称为 ckj)并将其设置在构造函数中。 [使用 GXT 文档中的 Person 示例]

  public class Person {
    private String name;
    private boolean ckj;
    private int age;

    public Person(String name, int age) {
      this.name = name;
      this.age = age;
      this.ckj=containsJapanese(name);
    }
    public String getName() {
      return name;
    }
    public int getAge() {
      return age;
    }

    public boolean containsCKJ(String s) {
    return s.codePoints()
            .anyMatch(codepoint -> (Character.UnicodeScript.of(codepoint) == Character.UnicodeScript.HAN
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_C                    
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_D                                                        
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_COMPATIBILITY
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_COMPATIBILITY_FORMS
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS_SUPPLEMENT
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_RADICALS_SUPPLEMENT
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_STROKES
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.ENCLOSED_CJK_LETTERS_AND_MONTHS
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.ENCLOSED_IDEOGRAPHIC_SUPPLEMENT                                                                                           
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.KANGXI_RADICALS
                    || Character.UnicodeBlock.of(codepoint) == Character.UnicodeBlock.IDEOGRAPHIC_DESCRIPTION_CHARACTERS

            ));
     }
  }

然后您可以在模板中使用 if 表达式。

 <tpl if="!ckj">
 //italics
 <tpl if="ckj">
 //no italics
