我試圖在javascript中從localstorage中拉出一串數據，併合並多個字符串的多個值。例如 我可以具有以下2個字符串從本地存儲在javascript中檢索多個字符串值
Bob;companyA;6141692120;[email protected];1 John St;;Bellevue;6056;;6;10;20.00;52.800000000000004;72.80;7.28;80.08;
Jane;companyB;6157692120;[email protected];1 Jack St;;Bellevue;6056;;6;10;20.00;52.800000000000004;72.80;7.28;80.08;
我想忽略前幾個和在串中的字符串添加的最後一個5或6一起從每個，所以值[13] A +值[13] B = X，會有大量的字符串，它們都有隨機數字，我附上了下面的JavaScript代碼，希望有人能指出我正確的方向。
windows.onload= getAllItems();
function getAllItems(){
var all = [];
for(var i = 0, j = localStorage.length; i < j; i++) {
all[i] = localStorage[i].split(';');
}
var sum = 0;
for(var i = 0, j = all.length; i < j; i++) {
sum += all[i][12];
}
var bags = all[9];
var distance = all[10];
var hdelivery_fee = all[11];
var hprice = all[12];
var htotal_notax = all[13];
var hgst = all[14];
var htotal_tax = all[15];
var hordernumber = all[16];
document.write('Number of Bags; ' + bags + '<br />');
document.write('Distance; ' + distance + '<br />');
document.write('Delivery Fee; $' + hdelivery_fee + '<br />');
document.write('Price of Bags; $' + hprice + '<br />');
document.write('Total Ex-GST; $' + htotal_notax + '<br />');
document.write('GST; $' + hgst + '<br />');
document.write('Total Inc GST; $' + htotal_tax + '<br />');
document.write('hordernumber; ' + hordernumber + '<br />');
}
而且它可能是值得一提的是，這是一個任務，因此我不能使用JSON或jQuery的任何能力
編輯：我已經改變了代碼下面給出的答案匹配，而且我認爲我已經將輸出從循環中提取出來了，但是我非常喜歡這個新特性，所以很多都是碰撞和錯過。它似乎沒有工作，當是即使它看起來像它應該（對我來說）
EDIT2：
增加對位置整個HTML頁面：爲localStorage的信息源
function source()
{
var newDate = new Date();
var itemId = newDate.getTime();
var values = new Array();
var name = document.getElementById("name").value;
var company = document.getElementById("company").value;
var contactnumber= document.getElementById("contactnumber").value;
var email = document.getElementById("email").value;
var address1 = document.getElementById("address1").value;
var address2 = document.getElementById("address2").value;
var suburb = document.getElementById("suburb").value;
var postcode = document.getElementById("postcode").value;
var comments = document.getElementById("comments").value;
var bags = document.getElementById("bags").value;
var distance = document.getElementById("distance").value;
var hdelivery_fee = document.getElementById("hdelivery_fee").value;
var hprice = document.getElementById("hprice").value;
var htotal_notax = document.getElementById("htotal_notax").value;
var hgst = document.getElementById("hgst").value;
var htotal_tax= document.getElementById("htotal_tax").value;
var hordernumber= document.getElementById("hordernumber").value;
values.push(name);
values.push(company);
values.push(contactnumber);
values.push(email);
values.push(address1);
values.push(address2);
values.push(suburb);
values.push(postcode);
values.push(comments);
values.push(bags);
values.push(distance);
values.push(hdelivery_fee);
values.push(hprice);
values.push(htotal_notax);
values.push(hgst);
values.push(htotal_tax);
values.push(hordernumber);
try {
localStorage.setItem(itemId, values.join(";"));
} catch (e) {
if (e == QUOTA_EXCEEDED_ERR) {
alert("Quota exceeded!");
}
}
}
EDIT3添加JavaScript的報告包括JavaScript。

試試這個。 – boisvert
你不應該被允許使用'document.write'或者 – Alexander
呵呵，我認爲使用'document.write'是新手的第一個指示 – user2397654
