通过单击按钮将文件存储在索引db中
我想用按钮创建一个Weabpp。通过单击按钮，我想将字符串存储在JavaScript索引eddb中。我需要一个功能。在Onupgradneed的活动中写下它，无法帮助我。我的准代码是：
<script>
function createDB(dbName, dbVersion) {
const request = indexedDB.open(dbName, dbVersion)
// upgrade needed
request.onupgradeneeded = e => {
const db = e.target.result
db.createObjectStore("wdesk")
console.log("Upgrade is called")
}
// successful
request.onsuccess = e => {
console.log("Success")
}
// error
request.onerror = e => {
console.log("Error")
}
}
<script>
<button onclick="">Store HelloWorld</button>
I want to create an weabpp with a button. By clicking on the button, I want to store a string in the JavaScript IndexedDB. I need a function. Writing it in the onupgradneeded event, could'nt help me. My acctual code is this:
<script>
function createDB(dbName, dbVersion) {
const request = indexedDB.open(dbName, dbVersion)
// upgrade needed
request.onupgradeneeded = e => {
const db = e.target.result
db.createObjectStore("wdesk")
console.log("Upgrade is called")
}
// successful
request.onsuccess = e => {
console.log("Success")
}
// error
request.onerror = e => {
console.log("Error")
}
}
<script>
<button onclick="">Store HelloWorld</button>

我认为，如果您只有一个字段，则可以将数据存储在本地存储中
I think if you have just one field you can store data in local storage
