我正在尝试让 chrome 扩展程序的默认弹出窗口充当设置页面
到目前为止的代码
[Manifest.json]
{
"name" : "test",
"description" : "it just works",
"version" : "1.0",
"manifest_version" : 2,
"permissions": [
"activeTab",
"declarativeContent",
"storage"
],
"icons": {
"16" : "icon_016.png"
},
"options_page": "options.html",
"content_scripts": [
{
"matches": [""],
"js": ["jquery.js", "script.js"]
}
],
"background": {
"scripts": ["background.js","options.js"],
"persistent": false
},
"browser_action":{
"default_icon": "icon_016.png",
"default_popup": "popup.html"
}
}
[popup.html]
<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

<script type="text/javascript" src="options.js"></script>
<style type='text/css'>
body {

}
.bc {
text-align: center;
height: 60px;
}
</style>
</head>
<body onload="loadOptions()">
<div class="bc container well">
<div class="input-group-addon">Refresh time (s)</div>
<input class="input" type="number" id="refresh">
<br /><br />
<div class="input-group-addon">Max Buy</div>
<input class="input" type="number" id="maxBuy">
<br /><br />
<div class="input-group-addon">Min Buy</div>
<input class="input" type="number" id="minBuy">
<br /><br />
<div class="input-group-addon">Buy at (%) discount</div>
<input class="input" type="number" id="discount">
<br /><br />
<button onclick="saveOptions()">Save</button>
<br />
<button onclick="eraseOptions()">Restore default</button>
</div>
</body>
</html>
[选项.js]
var defmax = 999999;
var defmin = 0;
var defdisc = 30;
var defref = 10;
function loadOptions() {
var maxBuy = localStorage["maxBuy"];
var minBuy = localStorage["minBuy"];
var discount = localStorage["discount"];
var refresh = localStorage["refresh"];
// value is not void/null
if (maxBuy == undefined) {
maxBuy = defmax;
}
if (minBuy == undefined) {
minBuy = defmin;
}
if (discount == undefined) {
discount = defdisc;
}
if (refresh == undefined) {
refresh = defref;
}
}
function saveOptions() {
var select1 = document.getElementById("maxBuy").value;
var select2 = document.getElementById("minBuy").value;
var select3 = document.getElementById("discount").value;
var select4 = document.getElementById("refresh").value;
localStorage["maxBuy"] = select1;
localStorage["minBuy"] = select2;
localStorage["discount"] = select3;
localStorage["refresh"] = select4;
chrome.storage.sync.set({
maxBuy: $('#maxBuy').val(),
minBuy: $('#minBuy').val(),
discount: $('#discount').val(),
refresh: $('#refresh').val()
});
}
function eraseOptions() {
localStorage.removeItem("maxBuy");
localStorage.removeItem("minBuy");
localStorage.removeItem("discount");
localStorage.removeItem("refresh");
location.reload();
}
这个想法是让默认弹出窗口充当设置页面，不言而喻，它应该显示当前的设置值，并且您应该能够更改它们。请记住，我对此很陌生，这只是来自各种项目的一堆代码，任何指针都会受到赞赏。
问题是为什么它不起作用，它不保存值，并且当您打开弹出窗口时也不显示默认值
最佳答案
你必须像这样存储
localStorage.setItem("lastname", "Arun");
localStorage.getItem("lastname");
