【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。提交后，表单会转到 PHP 文件，但我想显示一条消息而不是重定向。
这就是我所拥有的名为 FlashMessage 的消息组件
<template>

<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

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

$message = $_POST["message"];
$command = "OpenTicket";
$postData = array(
"deptid" => "$department",
"name" => "$name",

"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'];
}
?>
不知道哪里出错了。
【问题讨论】：
-
当您在表单中设置操作时，您的数据会转到后端，因此页面会因此而刷新。您必须使用 ajax 调用来防止页面刷新。
-
我不认为我可以使用 ajax，因为表单是使用 WHMCS API 提交的，我将添加 PHP 代码，但如果你能提供一个很好的例子。
