[英]Adding new objects to chrome local storage
HTML代码:
<select id="server">
<option value="kr">KR</option>
<option selected value="euw">EUW</option>
<option value="oce">OCE</option>
<option value="las">LAS</option>
<option value="ru">RU</option>
<option value="na">NA</option>
<option value="eune">EUNE</option>
<option value="br">BR</option>
<option value="lan">LAN</option>
<option value="tr">TR</option>
</select>
<input type="text" id="nickname" maxlength="16"></input></p>
<button id="save" class="flat-button">Save</button><br>
Javascritp代码:
function save_options() {
var server = document.getElementById('server').value;
var prenickname = document.getElementById('nickname').value;
var nickname = prenickname.replace(/(<([^>]+)>)/ig,""); //Remove html tags
chrome.storage.sync.set({
yourserver: server,
yournickname: nickname
}, function() {
var status = document.getElementById('status');
});
}
实际上,当我去保存(按按钮)到本地存储时,很明显它会覆盖我的旧对象。 我想这样做,它添加了一个新对象(如数组或列表),希望您理解我的意思。 结果必须是我可以存储不同的“服务器+昵称”,而不仅仅是一个。
要执行所需的操作,需要使用对象数组:您将使用chrome.storage.sync.get
获得数组的值,将新服务器和昵称添加到数组,然后使用chrome.storage.sync.set
覆盖现有值并保存。
您的数组如下所示:
data = [
{yourserver: 'server1', yournickname: 'nickname1'},
{yourserver: 'server2', yournickname: 'nickname2'},
{yourserver: 'server3', yournickname: 'nickname3'},
...
];
这是代码示例:
// Get all the items stored in the storage
chrome.storage.sync.get(function(items) {
if (Object.keys(items).length > 0 && items.data) {
// The data array already exists, add to it the new server and nickname
items.data.push({yourserver: server, yournickname: nickname});
} else {
// The data array doesn't exist yet, create it
items.data = [{yourserver: server, yournickname: nickname}];
}
// Now save the updated items using set
chrome.storage.sync.set(items, function() {
console.log('Data successfully saved to the storage!');
});
});
