Question

嗨，我只是从Regexs开始，并且正在尝试编写一个正则表达式来查找大括号内的字符串，同时保持大括号

@SuppressWarnings({"JavaReflectionMemberAccess", "deprecation"})
public static void setCursorDrawableColor(EditText editText, int color) {

    try {
        Field cursorDrawableResField = TextView.class.getDeclaredField("mCursorDrawableRes");
        cursorDrawableResField.setAccessible(true);
        int cursorDrawableRes = cursorDrawableResField.getInt(editText);
        Field editorField = TextView.class.getDeclaredField("mEditor");
        editorField.setAccessible(true);
        Object editor = editorField.get(editText);
        Class<?> clazz = editor.getClass();
        Resources res = editText.getContext().getResources();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            Field drawableForCursorField = clazz.getDeclaredField("mDrawableForCursor");
            drawableForCursorField.setAccessible(true);
            Drawable drawable = res.getDrawable(cursorDrawableRes);
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawableForCursorField.set(editor, drawable);
        } else {
            Field cursorDrawableField = clazz.getDeclaredField("mCursorDrawable");
            cursorDrawableField.setAccessible(true);
            Drawable[] drawables = new Drawable[2];
            drawables[0] = res.getDrawable(cursorDrawableRes);
            drawables[1] = res.getDrawable(cursorDrawableRes);
            drawables[0].setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawables[1].setColorFilter(color, PorterDuff.Mode.SRC_IN);
            cursorDrawableField.set(editor, drawables);
        }
    } catch (Throwable t) {
        Log.w(TAG, t);
    }
}

我已经在这里仔细查看了答案： Regular expression to find string inside curly brackets Javascript

这几乎可以满足我的要求，只是它只返回大括号内的内容。我想保留大括号。

Answer 1

var myString = "This is a {nice} text to search for a {cool} substring",
    pattern = /\{[^{}]*\}/g;

console.log(myString.match(pattern));

这是对您链接的问题的答案的修改。我在模式的开头添加了{，并在结尾处删除了}周围的前瞻。
