我们如何将字符串存储在localStorage中? [英] How do we store a string in localStorage?
问题描述
我正在学习javascript，xml和html.对于家庭作业，我需要从XML文件的某些节点检索一些数据，将数据连接起来，然后将连接后的字符串存储在localStorage中.我在将串联的字符串存储在localStorage中遇到麻烦.我认为问题出在这两行-
I'm learning javascript, xml, and html. For a homework assignment, I need to retrieve some data from some nodes of a XML file, concatenate the data, and store the concatenated string in localStorage. I am having trouble in storing the concatenated string in localStorage. I believe the issue is in these two lines -
var s_data = localStorage [students];
$(#clickme").text(学生的名字:" + s_data);
var s_data = localStorage[students];
$("#clickme").text("Students' first names: " + s_data);
有人可以看一下并给我一些如何修复它的提示吗?预先感谢您的帮助.
Can someone take a look and give me some tips on how to fix it? Thank you in advance for your help.

推荐答案
您可以使用 localStorage 和 getItem()进行检索
You can use the setItem() to set a value to the localStorage and getItem() to retrieve it
例如:
localStorage.setItem('mykey', 'somevalue')
