问题描述

是否可以插入localstorage或是否有其他方式存储？

Is this possible to insert to localstorage or is there other way to store this?

var compressed = function(){
    $('.whole_wrap_of_editcriteria').css('display','none');
    $('#wrappler').css('display','block');
    $('#li_addcriteria').css('display','none');
    $('#li_menu1').addClass('active');
    $('#home').removeClass('active');
    $('#menu1').addClass('active');
    $('#title_panel').html('Edit criteria scoring');
}
compressed();
localStorage.setItem('compressed', compressed());
//i also try set as JSON.stringify but its undefined

});

推荐答案

我不知道为什么你想要那个，我不推荐它，但你可以用 toString 来做。

I don't know why you'd want that, I would not recommend it, but you can do it using toString.

存储它：

var myFunc = function (){
  alert('Hello world!');
};

// Store it as a String
localStorage.setItem('compressedFunc', myFunc.toString());

稍后，检索它：

var compressedFunc = localStorage.getItem('compressedFunc');

// Convert the String back to a function
var myFunc = eval('(' + compressedFunc + ')');

// Use it
myFunc();
