localStorage的＆安培; JSON：我如何删除只有1关键内部阵列，因为localstorage.removeItem需要整个关键 [英] Localstorage & JSON: How can I delete only 1 array inside a key since localstorage.removeItem requires the entire key

问题描述

我有这个在我的localStorage：

I have this in my localStorage:

[{"id":"item-1","href":"google.com","icon":"google.com"},
{"id":"item-2","href":"youtube.com","icon":"youtube.com"},
{"id":"item-3","href":"google.com","icon":"google.com"},
{"id":"item-4","href":"google.com","icon":"google.com"},
{"id":"item-5","href":"youtube.com","icon":"youtube.com"},
{"id":"item-6","href":"asos.com","icon":"asos.com"},
{"id":"item-7","href":"google.com","icon":"google.com"},
{"id":"item-8","href":"mcdonalds.com","icon":"mcdonalds.com"}]

我怎么只能删除 ID：项目3时 localstorage.removeItem 需要整个密钥

How can I delete only the id:item-3 when localstorage.removeItem requires entire key?

我用这个方法来更新数组中的一个特定的值： http://jsfiddle.net/Qmm9g/因此，使用我想删除特定阵列的方法相同。

I use this method to update a specific value in an array: http://jsfiddle.net/Qmm9g/ so using the same method I want to delete specific array.

请注意，已经有一个按钮来删除。该按钮我想这将删除整个阵列（函数{ID：项-3，HREF：google.com，图标：google.com} ）使用 ID：项目-3

Note that there is already a button to delete. That button I want a function which will delete the entire array ({"id":"item-3","href":"google.com","icon":"google.com"}) with ID:item-3

推荐答案

这样的事情会的工作，我不知道，如果它是的最的方式做到这一点，虽然。也许有一个更好的本地存储特殊的方式 -

Something like this would work, I'm not sure if it's the best way to do it though. There maybe a better local storage specific way -

var json = JSON.parse(localStorage["results"]);
for (i=0;i<json.length;i++)
            if (json[i].id == 'item-3') json.splice(i,1);
localStorage["results"] = JSON.stringify(json);
