无法读取未定义的属性（读取“getTextInputValue”）discord.js v14

Question

我需要它来输出这个人在模态窗口中写的内容。如果你删除

const reasonn = interaction.fields.getTextInputValue("reason");

线，模式窗口打开，但发送时，机器人崩溃，因为它没有收到响应。

错误：

D:\v144\Events\interactions\Suggestion.js:43
                        const reasonn = interaction.fields.getTextInputValue("reason");
                                                           ^

代码：

const { PermissionFlagsBits, EmbedBuilder, IntegrationApplication, TextInputStyle, TextInputBuilder, ModalBuilder, ActionRowBuilder } = require("discord.js");
const suggestionSchema = require("../../Models/Suggestion");

module.exports = {
    name: "interactionCreate",
    async execute(interaction) {
        const { member, guildId, customId, message } = interaction;

        if (!interaction.isButton()) return;

        if (customId == "suggest-accept" || customId == "suggest-decline") {
            if (!member.permissions.has(PermissionFlagsBits.Administrator))
                return interaction.reply({ content: "No permissions!", ephemeral: true });

            suggestionSchema.findOne({ GuildID: guildId, MessageID: message.id }, async (err, data) => {
                if (err) throw err;

                if (!data)
                    return interaction.reply({ content: "No data was found.", ephemeral: true });

                const embed = message.embeds[0];

                if (!embed)
                    return interaction.reply({ content: "No embed was found.", ephemeral: true });

                switch (customId) {
                    case "suggest-accept":
                        const modal = new ModalBuilder()
                        .setTitle('Accept')
                        .setCustomId('modal')

                        const reason = new TextInputBuilder()
                        .setCustomId('reason')
                        .setRequired(true)
                        .setLabel('Reason')
                        .setStyle(TextInputStyle.Short);

                        const reasons = new ActionRowBuilder().addComponents(reason)

                        modal.addComponents(reasons)
                        interaction.showModal(modal)

                        const reasonn = interaction.fields.getTextInputValue("reason");

                        embed.data.fields[2] = { name: "Status", value: "Accepted", inline: true };
                        embed.data.fields[3] = { name: "Reason", value: `${reasonn}`, inline: true };
                        const acceptedEmbed = EmbedBuilder.from(embed).setColor("Green");

                        message.edit({ embeds: [acceptedEmbed] });
                        interaction.reply({ content: "Suggestion accepted.", ephemeral: true });
                        break;
                    case "suggest-decline":
                        embed.data.fields[2] = { name: "Status", value: "Declined", inline: true };
                        const declinedEmbed = EmbedBuilder.from(embed).setColor("Red");

                        message.edit({ embeds: [declinedEmbed] });
                        interaction.reply({ content: "Suggestion declined.", ephemeral: true });
                        break;
                }
            });
        }
    }
}

我试图做到这一点，以便当一个人点击一个按钮时，会弹出一个带有原因的模式窗口。他必须在那里输入，原因被建议替换。

这是因为顶部有一个类型保护器。我非常喜欢提前返回，但是如果 interaction 不是 ButtonInteraction，这个 if (!interaction.isButton()) return; 将停止执行它下面的任何代码。因此，您的代码仅适用于 ButtonInteractions 而那些没有 fields 属性，这就是您收到错误的原因。

您需要检查 interaction 是否为 ModalSubmitInteraction。那就是你模态的fields。

module.exports = {
  name: 'interactionCreate',
  async execute(interaction) {
    const { member, guildId, customId, message } = interaction;

    if (interaction.isModalSubmit()) {
      // all code that you want to run after the user submitted the modal
      // interaction.fields.getTextInputValue() is available here
    }

    if (interaction.isButton()) {
      // all code that you want to run after the user clicked a button
      // interaction.fields.getTextInputValue() throws error here
    }
  },
};
