我遇到了一个小问题,我试图保存输入字段的值" a1"进入本地存储,但由于某种原因,它没有保存。我似乎无法弄清问题是什么......
感谢所有帮助!
已修复:将脚本放在底部。
<!DOCTYPE html>
<html>
<head>
<script src="jquery.js"></script>
<script>
document.getElementById('a1').onkeyup = function() {
var a1 = document.getElementById('a1').value;
localStorage.setItem('a1', a1);
};
</script>
<link rel="stylesheet" type="text/css" href="test.css">
</head>
<body>

答案 0 :(得分:3)
将代码放在页面底部。它在呈现元素之前运行,这意味着事件无法注册到元素。
断裂:
<script>
document.getElementById('a1').onkeyup = function() {
var a1 = document.getElementById('a1').value;
localStorage.setItem('a1', a1);
};
</script>
<input class="input-field" id="a1" type="text" value="0" />

已修复(localStorage
个可用于片段中除外):
<input class="input-field" id="a1" type="text" value="0" />
<script>
document.getElementById('a1').onkeyup = function() {
var a1 = document.getElementById('a1').value;
localStorage.setItem('a1', a1);
};
</script>
