create a CRUD web application with Google Apps Script
To create a CRUD web application with Google Apps Script, we will use Google Sheets as our database and build a web interface using HTML and JavaScript. Here is an example code for a basic CRUD web application:
Step 1: Create a new Google Sheet
To begin, open a new Google Sheet and give it a name. This sheet will serve as the database for our CRUD application. In the first row, add the following headers: "ID", "Name", "Email", "Phone".
Step 2: Create a new Google Apps Script
Next, click on "Tools" in the menu bar and select "Script editor". This will open the Google Apps Script editor. In the editor, create a new script file and give it a name.
Step 3: Create the HTML interface
In the script editor, create a new HTML file by clicking on "File" -> "New" -> "Html file". Name the file "index". In this file, we will create the interface for our CRUD application. Here is an example code:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<table>
<tr>
<td>ID:</td>
<td><input type="text" id="id"></td>
</tr>
<tr>
<td>Name:</td>
<td><input type="text" id="name"></td>
</tr>
<tr>
<td>Email:</td>
<td><input type="text" id="email"></td>
</tr>
<tr>
<td>Phone:</td>
<td><input type="text" id="phone"></td>
</tr>
</table>
<button onclick="createRecord()">Create</button>
<button onclick="readRecord()">Read</button>
<button onclick="updateRecord()">Update</button>
<button onclick="deleteRecord()">Delete</button>
<br><br>
<table id="output"></table>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="code.gs"></script>
</body>
</html>
This HTML code creates a table with four input fields for the ID, name, email, and phone. It also includes four buttons for each of the CRUD operations. Finally, it includes an empty table element that we will use to display the output.
Step 4: Create the JavaScript functions
In the same HTML file, we will create JavaScript functions that call the CRUD functions defined in the Google Apps Script. Here is an example code:
<script>
function createRecord() {
var id = $("#id").val();
var name = $("#name").val();
var email = $("#email").val();
var phone = $("#phone").val();
google.script.run.createRecord(name, email, phone);
$("#id").val("");
$("#name").val("");
$("#email").val("");
$("#phone").val("");
}
function readRecord() {
var id = $("#id").val();
google.script.run.withSuccessHandler(function(output) {
$("#output").empty();
$("#output").append("<tr><td>ID</td><td>Name</td><td>Email</td><td>Phone</td></tr>");
$("#output").append("<tr><td>" + output[0] + "</td><td>" + output[1] + "</td><td>" + output[2] + "</td><td>" + output[3] + "</td></tr>");
}).readRecord
