[英]How to append HTML form data into a doc/txt file with javascript
I have a form with multiple inputs and drop-downs, I want to store this data (keep appending future data) into a text file.我有一个包含多个输入和下拉列表的表单,我想将此数据(继续附加未来的数据)存储到一个文本文件中。 I don't wish to use PHP or any other language.
我不想使用 PHP 或任何其他语言。
I need to fetch back this data later probably into excel, so storing it in json would be a possible approach.我需要稍后将这些数据取回可能到 excel 中,因此将其存储在 json 中是一种可能的方法。
Please guide me on how to do this, I am a beginner in javascript, also suggest if any better approach is possible using just javascript (vanilla).请指导我如何做到这一点,我是 javascript 的初学者,还建议仅使用 javascript(香草)是否有更好的方法。
Hi i've built a fully working example using vanilla javascript for you.嗨,我已经为您使用香草 javascript 构建了一个完整的工作示例。 In this example there is a form with 3 fields.
在此示例中,有一个包含 3 个字段的表单。 and a submit button.
和一个提交按钮。 When the submit is clicked the function handle submit is invoked.
单击提交时,将调用 function 句柄提交。 Than a blob file is created with the desired text.
然后使用所需的文本创建一个 blob 文件。 And it automatically downloads the file.
它会自动下载文件。
<html>
<head>
<script>
function makeFile(text) {
var newFile = new Blob(text.split(), { type: 'text/plain' })
var newFileUrl = window.URL.createObjectURL(newFile);
var link = document.getElementById('submit');
link.href = newFileUrl;
link.download = true;
}
var handleSubmit = () => {
var field1 = document.getElementById('field1').value
var field2 = document.getElementById('field2').value
var field3 = document.getElementById('field3').value
makeFile(`${field1},${field2},${field3}`);
}
</script>
</head>
<body>
<form id="form1">
<div>
<span>field1:</span>
<input type="text" id='field1' />
</div>
<div>
<span>field2:</span>
<input type="text" id='field2' />
</div>
<div>
<span>field3:</span>
<input type="text" id='field3' />
</div>
</form>
<a href="#" download id="submit" onclick="handleSubmit()">Submit</a>
</body>
</html>
