Javascript遍历变量
Javascript遍历变量
提问于 2018-07-31 01:10:34
现在，这是我当前的代码，我正在尝试找到一种循环遍历我已经声明的变量的方法(假设变量1-9已经有值)。我只想知道这是否可能？
var title;
var brief;
var hover;
var whatTitle;
var whatDesc;
var whyTitle;
var whyDesc;
var funTitle;
var funDesc;
var titles = [];
var briefs = [];
var hovers = [];
var whatTitles = [];
var whatDescs = [];
var whyTitles = [];
var whyDescs = [];
var funTitles = [];
var funDescs = [];
var obj = {'titles' : title};
if(localStorage.getItem('titles') != null) {
var tmp = JSON.parse(localStorage.getItem('titles'));
for(var i = 0;i<tmp.length;i++) {
titles.push(tmp[i]);
}
}
titles.push(obj);
localStorage.setItem("titles", JSON.stringify(titles));如果我们打印出循环代码，我想要的输出：
var obj = {'titles' : title};
if(localStorage.getItem('titles') != null) {
var tmp = JSON.parse(localStorage.getItem('titles'));
for(var i = 0;i<tmp.length;i++) {
titles.push(tmp[i]);
}
}
titles.push(obj);
localStorage.setItem("titles", JSON.stringify(titles));
var obj = {'briefs' : brief};
if(localStorage.getItem('briefs') != null) {
var tmp1 = JSON.parse(localStorage.getItem('briefs'));
for(var i = 0;i<tmp.length;i++) {
briefs.push(tmp[i]);
}
}
briefs.push(obj);
localStorage.setItem("briefs", JSON.stringify(briefs));
var obj = {'hovers' : hover};
if(localStorage.getItem('hovers') != null) {
var tmp2 = JSON.parse(localStorage.getItem('hovers'));
for(var i = 0;i<tmp.length;i++) {
hovers.push(tmp[i]);
}
}
hovers.push(obj);
localStorage.setItem("hovers", JSON.stringify(hovers));
