我正在尝试获取和排序 localStorage 中的所有项目并将其输出到 HTML 页面。
这就是我正在做的事情:
<script>
function ShoppingCart() {
var totalPrice = 0;
var output;
var productName;
var productAlbum;
var productQuantity;
var productPrice;
var productSubTotal = 0;
var totalPrice;
for (var i = 0; i < localStorage.length-1; i++){
var keyName = localStorage.key(i);
if(keyName.indexOf('Product_')==0) // check if key startwith 'Product_'
{
var product = localStorage.getItem('Product_'+i);
var result = JSON.parse(product);
var productName;
var productAlbum;
var productQuantity;
var productPrice;
var productSubTotal = 0;
var totalPrice;
productName = result.name
productAlbum = result.album;
productQuantity = result.quantity;
productPrice = parseFloat(result.price).toFixed(2);
productSubTotal = parseFloat(productQuantity * productPrice).toFixed(2);
outputName = "<div id='cart-table'><table><tr><td><b>NAME: </b>" + productName + "</td></tr></div>" ;
outputAlbum = "<tr><td><b>ALBUM: </b>" + productAlbum + "</td></tr>" ;
outputQuantity = "<tr><td><b>QUANTITY: </b>" + productQuantity + "</td></tr>";
outputPrice = "<tr><td><b>PRICE: </b> EUR " + productPrice + "</td></tr>";
outputSubTotal = "<tr><td><b>SUB-TOTAL: </b> EUR " + productSubTotal + "</td></tr></table><br><br>";
var outputTotal = "<table><tr><td><b>TOTAL:</b> EUR " + totalPrice + "</td></tr></table>";
var TotalOutput = outputName + outputAlbum + outputQuantity + outputPrice + outputSubTotal + outputTotal;
document.getElementById("Cart-Contents").innerHTML=TotalOutput;
}
}
alert(TotalOutput);
}
window.onload = ShoppingCart;
</script>
唯一正在输出的项目是 localStorage 中名为“Proudct_0”的项目。其他不显示!
这就是我在 localStorage 中所拥有的:http: //i.imgur.com/sHxXLOL.png
知道为什么会这样吗?
