我有一個表格行看起來像jQuery的:錶行
的HTML看起來像
當用戶更改名稱字段中的我通過「選擇」裏面的值獲得選擇命名爲DropChanged函數。獲取參考號後,選擇我想更改優惠券數量選擇框的值。我如何使用Jquery獲得對它的引用?表中還會有很多這樣精確的行。
更新:這裏是虛擬的HTML代碼和jsfiddle link
<table id="competitors_table" width="100%" style="border-bottom: #000000 solid 1px;">
<tbody>
<tr>
<td>Name:<select name="CompetitorIDs_Setting_[]" onchange="nameDropDownChanged(this);">
