使用此选项清除localStorage：

localStorage.clear();

手动按钮：

<script>
function ask() {
if (confirm('Clear localStorage?') == true) {
localStorage.clear()
location.reload()
}
else {
alert('Nothing happend')
}
}
}
</script>
<style>
button {border-width:0px;background-color:#efefef;padding:5px;width:5cm;margin:5px;}
</style>
<button onclick=ask()>Clear localStorage</button>

这里有一个函数，允许您删除所有localStorage项，但有例外。这个函数需要jQuery。你可以下载要点。

你可以这样称呼它

let clearStorageExcept = function(exceptions) {
  let keys = [];
  exceptions = [].concat(exceptions); // prevent undefined

  // get storage keys
  $.each(localStorage, (key) => {
    keys.push(key);
  });

  // loop through keys
  for (let i = 0; i < keys.length; i++) {
    let key = keys[i];
    let deleteItem = true;

    // check if key excluded
    for (let j = 0; j < exceptions.length; j++) {
      let exception = exceptions[j];
      if (key == exception) {
        deleteItem = false;
      }
    }

    // delete key
    if (deleteItem) {
      localStorage.removeItem(key);
    }
  }
};

使用此选项清除localStorage：

localStorage.clear();

如果需要清除本地存储数据，请使用：

localStorage.clear()

要从本地存储中删除特定项目，请执行以下操作：

localStorage.removeItem('Item')

window.localStorage.clear(); //try this to clear all local storage
