javascript - 在提交表单 Vue.js 时显示 flash 消息

问题描述

我正在尝试创建一个联系表单，我已经完成了，但现在我正在尝试在提交时创建一个提交 Flash 消息。提交时，表单会转到 PHP 文件，但我想显示一条消息而不是重定向。

这是我所拥有的消息组件，称为FlashMessage

<template>
  <div
    class="flex items-center bg-green-500 text-white text-sm font-bold px-4 py-3 mb-6"
    role="alert"
    v-show="show"
  >
    <svg class="fill-current w-4 h-4 mr-2" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 20">
      <path

      />
    </svg>
    <p>{{ body }}</p>
  </div>
</template>

<script>
export default {
  name: "FlashMessage",
  props: {
    message: {
      type: String,
      required: true
    }
  },
  data() {
    return {
      show: false,
      body: ""
    };
  },
  created() {
    if (this.message) {
      this.flash(this.message);
    }
    window.events.$on("flash", message => this.flash(message));
  },
  methods: {
    flash(message) {
      this.show = true;
      this.body = message;

      setTimeout(() => {
        this.hide();
      }, 3000);
    },
    hide() {
      this.show = false;
    }
  }
};
</script>

这是表格

<FlashMessage message="Message sent!" />

<form @submit.prevent="onSubmit" action="./backend/contact.php" method="POST">
<div class="mb-4">
  <label class="block" for="name">
    <span class="text-gray-900">Full name</span>

<div class="mb-4">

<div class="mb-4">

      id="message"

  </label>
</div>

<div class="flex mt-6">

    <span class="ml-2">

    </span>
  </label>
</div>

<div class="flex mt-6">
  <label class="flex items-center">
    <button
      type="submit"
      class="flex items-center py-3 px-6 border rounded bg-gray-800 hover:bg-gray-900 font-medium text-white transition duration-300 ease-in-out"
    >
      <i class="fas fa-paper-plane mr-4"></i>
      Send
    </button>
  </label>
</div>
</form>

<script>
import FlashMessage from "../components/FlashMessage";
import FeaturesWGrid from "../components/FeaturesWGrid";
import Grid from "../components/Grid";
import GridItem from "../components/GridItem";

export default {
  name: "Contact",
  components: {
    FlashMessage,
    FeaturesWGrid,
    Grid,
    GridItem
  },
  methods: {
    onSubmit() {
      show: true;
    }
  }
};
</script>

联系人.php

<?php
include("/home/hostedca/redacted/includes/api.php");

$api_identifier = "";
$api_secret = "";

$postfields = array(
    "identifier" => $api_identifier,
    "secret" => $api_secret,
    "action" => "OpenTicket",
    "responsetype" => "json",
);

$name = $_POST["name"];
$email = $_POST["email"];
$department = $_POST["department"];
$message = $_POST["message"];

$command = "OpenTicket";
$postData = array(
    "deptid" => "$department",
    "name" => "$name",
    "email" => "$email",
    "subject" => "Contact form Inquiry from $name for $department",
    "message" => "$message",
    "priority" => "Medium",
    "markdown" => false,
);

$adminUsername = "admin";

// Call the localAPI function
$results = localAPI($command, $postData, $adminUsername);
if ($results['result'] == 'success') {
    echo 'Message sent successfully!';
} else {
    echo "An Error Occurred: " . $results['result'];
}
?>

不知道我哪里错了。

解决方案

您可以从子组件中删除“v-show”条件FlashMessage.vue。直接使用父级中的值，

在部分中设置show为false默认值data。改变onSubmit()方法如下

export default {
  name: "Contact",
  data:()=>{
    return {
      show:false
    }
  },
  methods: {
    onSubmit() {
      this.show = true;
      setTimeout(()=>{
        this.show = false;
      },3000);
      // rest of your logic
    }
  }
};

在调用子组件时添加v-if或v-show条件如下

<FlashMessage message="Message sent!" v-if = "show"/>
