jquery-easyui的拖放购物车范例

阅读更多

利用easyui的拖放能力可以轻松创建购物车,看一个例子:

 

1、显示产品HTML

<ul class="products">
    <li>
        <a href="#" class="item">
            <img src="shirt1.gif"/>
            <div>
                <p>Balloon</p>
                <p>Price:$25</p>
            </div>
        </a>
    </li>
    <li>
        <a href="#" class="item">
            <img src="shirt2.gif"/>
            <div>
                <p>Feeling</p>
                <p>Price:$25</p>
            </div>
        </a>
    </li>
    <!-- other products -->
</ul>

2、购物车HTML:

<div class="cart">
    <h1>Shopping Cart</h1>
    <table id="cartcontent" style="width:300px;height:auto;">
        <thead>
            <tr>
                <th field="name" width=140>Name</th>
                <th field="quantity" width=60 align="right">Quantity</th>
                <th field="price" width=60 align="right">Price</th>
            </tr>
        </thead>
    </table>
    <p class="total">Total: $0</p>
    <h2>Drop here to add to cart</h2>
</div>

3、编写拖放代码:

$('.item').draggable({
    revert:true,
    proxy:'clone',
    onStartDrag:function(){
        $(this).draggable('options').cursor = 'not-allowed';
        $(this).draggable('proxy').css('z-index',10);
    },
    onStopDrag:function(){
        $(this).draggable('options').cursor='move';
    }
});
 
$('.cart').droppable({
    onDragEnter:function(e,source){
        $(source).draggable('options').cursor='auto';
    },
    onDragLeave:function(e,source){
        $(source).draggable('options').cursor='not-allowed';
    },
    onDrop:function(e,source){
        var name = $(source).find('p:eq(0)').html();
        var price = $(source).find('p:eq(1)').html();
        addProduct(name, parseFloat(price.split('$')[1]));
    }
});

4、更新购物篮代码:

var data = {"total":0,"rows":[]};
var totalCost = 0;
function addProduct(name,price){
    function add(){
        for(var i=0; i<data.total; i++){
            var row = data.rows[i];
            if (row.name == name){
                row.quantity += 1;
                return;
            }
        }
        data.total += 1;
        data.rows.push({
            name:name,
            quantity:1,
            price:price
        });
    }
    add();
    totalCost += price;
    $('#cartcontent').datagrid('loadData', data);
    $('div.cart .total').html('Total: $'+totalCost);
}
