Question

我有一个带单选按钮的表，在第一列，选项是：

'---'
'没有股票'
'有库存'

在第二列，选项为：

'---'
'没有股票'
'低'
'中'
'高'

现在我想要做的是，当用户点击第一列上的“无库存”时，应检查第二列上的“无库存”单选项。

这就是我正在做的事情：

HTML：

<table border='1'>

    <tr>
        <td class="valign_top" style="text-align:left;">
            <div class="radio_field">
                <input type="radio" class="stock_avail" id="93_stock_avail_0" name="93_stock_avail" value="0" checked=""> ---

            </div>
        </td>
    </tr>

</table>

JavaScript的：

$(document).ready(function(){
    $('.stock_avail').click(function(){

        var value = $(this).val();
        console.log("value: " + value);

        if(value=='No'){
            $(this).next('td').find('radio').val(2);
        }

    });
});

任何想法如何做到这一点？ TIA !!!

        var value = $(this).val();
        console.log("value: " + value);

        if(value=='No'){
            $(this).closest("td").next().find("input[value=1]").attr("checked",true);
        }

    });
});

Answer 2

$(document).ready(function(){
    $('.stock_avail').click(function(){
        if($(this).val()=='No'){
            $(this).parent().parent().next().find(':radio:eq(1)').attr('checked','checked');
           //assuming No stock will be always a second radio option 
        }
    });
});
