JQuery setting a local storage variable
提问by Marshall Tigerus
I'm having some trouble getting a local storage variable to store the proper value. The jist of it is I want to display the contents of the local variable, then if the user clicks, it pulls the data from an .xml file, saving it to a local variable.
我在获取本地存储变量来存储正确的值时遇到了一些麻烦。它的要点是我想显示局部变量的内容，然后如果用户单击，它会从 .xml 文件中提取数据，将其保存到局部变量中。
Problem is, that it doesn't save to the local variable properly. I have tried a variety of syntax to get it to work and I am out of ideas.
问题是，它没有正确保存到局部变量。我尝试了各种语法来让它工作，但我没有想法。

you have a syntax error, need to get
你有一个语法错误，需要得到
localStorage.setItem('titles', $('#results').text());
or
或者
localStorage.setItem('titles', titles.text());
