選擇器選擇多行中的所有單選按鈕。我想在點擊單選按鈕輸入框的名字排

Question

我有以下佈局：

我留意美元符號（$）和百分號（％）無線電使用下面的選擇按鈕的變化：

$("#facultyTable input:radio.dollar,#facultyTable input:radio.percent").change(function(){ 
    //What to do here? 
}); 

我試圖用.parent()選擇，不過問題是，因爲我有選擇的所有，我不能簡單地得到父一行<tr>單選按鈕，它是關閉所有的行。我想要的是以下內容：按下單選按鈕後，jquery將文本框的值在同一行中的左側取出。我怎樣才能做到這一點？

這裏是如果需要的表格佈局：

<table id="facultyTable"> 
     <thead> 
      <tr> 
       <th>Username</th> 
       <th>Payment Distribution</th> 
       <th>Account Number (Optional)</th> 
      </tr> 
     </thead> 
     <tbody><tr> 
      <td><input name="username[]" value="klarson" data-cip-id="cIPJQ342845639" style="background-image: none; background-position: 0% 0%; background-repeat: repeat;"></td>

Answer 1

你可以試試這個

$("#facultyTable input:radio.dollar,#facultyTable input:radio.percent").change(function(){ 

    var username = $(this).parent("td").prev("td").find("input:text").val(); 

});
