Question

您好我是javaScript / jquery的新手。我有以下由框架自动生成的HTML代码。

<tr class="alternate-row">
    <td>17 July, 2012</td>
    <td>AM Shipment</td>
    <td>Generated</td>
    <td>
        <form method="post" action="" id="ListTruckSheets_o_7" class="basic-form" onsubmit="javascript:submitFormDisableSubmits(this)" name="ListTruckSheets_o_7">//I have the name of this form.
            <input type="hidden" name="shipmentId"  value="10310" id="ListTruckSheets_shipmentId_o_7">
            <input type="hidden" name="Report" id="truckSheet_o_7" onclick="javascript:setSelectedRoute(this, 10310);">
            <input type="hidden" name="abstractReport" id="routeAbstract_o_7" onclick="javascript:setSelectedRoute(this, 10310);">
            <input type="hidden" name="milkDeliverySchedule" id="deliverySchedule_o_7"  onclick="javascript:setSelectedRoute(this, 10310);">
            <input type="hidden" name="cancelShipment" id="ListTruckSheets_cancelShipment_o_7">
        </form>
        <td>
            <a class="buttontext" href="/myportal/control/KVGenerateTruckSheet.txt?shipmentId=10310&amp;reportTypeFlag=trucksheet"  target="_blank" onclick="javascript:setSelectedRoute(this, 10310);" title="Report">Truck Sheet Report</a>
        </td>
        <td>
            <a class="buttontext" href="/myportal/control/KVGenerateTruckSheet.txt?shipmentId=10310&amp;reportTypeFlag=abstract" target="_blank" onclick="javascript:setSelectedRoute(this, 10310);" title="Abstract Report">Route Abstract Report</a>
        </td>
        <td>
            <a class="buttontext" href="/myportal/control/MilkDeliveryScheduleReport.txt?hipmentId=10310&amp;reportTypeFlag=milkDeliverySchedule" target="_blank" onclick="javascript:setSelectedRoute(this, 10310);" title="Milk Delivery Schedule">Delivery Schedule</a>
        </td>
        <td>
            <form method="post" action="/myportal/control/cancelLMSShipment" target="_blank"    onsubmit="javascript:submitFormDisableSubmits(this)" name="ListTruckSheets_o_7_0_o_cancelShipment">
                <input name="shipmentId" value="10310" type="hidden">
            </form>
            <a class="buttontext" href="javascript:document.ListTruckSheets_o_7_0_o_cancelShipment.submit()">Cancel</a>
        </td>
</tr>

使用onclick我调用了一个javaScript函数，它获取url并为其添加一个参数。我有表单的名称或ID（'ListTruckSheets_o_7'）。使用表单名称或Id我需要找到父tr并标识我想要的正确的td并将参数设置为其url。这是我目前正在搞乱的代码。

function setSelectedRoute(existingUrl, shipmentId) {
     var form = $("input[value=" + shipmentId + "]").parent(); //formName: ListTruckSheets_o_7
     var routeId = form.find("option:selected").text();
     var resultUrl = existingUrl + "&facilityId=" + routeId;
     $('.buttontext').attr('href', resultUrl); // this is setting resultUrl to all the .buttontext class elements but I need to set resultUrl to only specific selected td.
}

所以，可能是，我需要找到父tr并返回到特定的td并将resultUrl设置为它。我不知道该怎么做。我希望我对自己的问题很清楚。谢谢..

您可以测试一下：

form
  .closest('tr')   // go parent tr of form
  .find('.specific_selected_td') // find td, here specific_selected_td is 
                                 // assumed class to selected td
                                 // you may have something different 
  .find('a')  // find anchor tag within that specific td
  .attr('href', resultUrl); // set href

编辑后

更改

$('.buttontext').attr('href', resultUrl);

到

$(existingUrl).attr('href', resultUrl);

此处，existingUrl表示点击的a。

使用jquery向链接添加参数
