问题描述
我正在使用 jquery-indexed-db插件创建一个示例项目只是为了学习 indexeddb .
I am using the jquery-indexed-db plugin to make a sample project just to go about learning indexeddb.
JS代码
$(function() {
/*Loggers*/
write = function(info) {
console.info(info);
}
writeError = function(e) {
console.info(e);
}
/*Settings*/
dbName = "testDB";
osName = "list";
/*DB Init*/
db = $.indexedDB(dbName).then(write, writeError)
/*ObjectStore Init*/
objectStore = db.objectStore(osName, false);
/*Adding a new record*/
$("#submit").click(function(){
objectStore.add(
{
"Name": $("#name").val(),
"Age": $("#age").val()
},
$("#id").val()
).then(write, writeError);
$("#id").val("");
$("#name").val("");
$("#age").val("");
});
});
HTML代码
<ul>
<li>
<input type="text" id="id" placeholder="Id" />
</li>
<li>
<input type="text" id="name" placeholder="Name" />
</li>
<li>
<input type="text" id="age" placeholder="Age" />
</li>
<li>
<input type="button" id="submit" name="submit" value="Submit"/>
</li>
</ul>
单击提交按钮时出现异常.错误如下
I am getting an exception when i click the submit button. The error is as follows
IDBDatabaseException

推荐答案
您需要先创建事务,然后才能打开对象存储.
You need to create a transaction before you can open an object store.
$.indexedDB(dbName).transaction([osName], 1).then(function(transaction){
objectStore = transaction.objectStore(osName);
});
顺便说一句,这是您提供的完整脚本吗?我缺少创建对象存储的部分.
Btw is that the complete script you gave? I'm missing the part where you create an object store.
