        </form> 

       </nobr> 
       </td> 
       </tr> 
</table> 

但我无法弄清楚如何从同一行我点击获得的输入

$('input[type=image]').click(function(){ 
    // insert voodoo go get inputs here 
    // ajax call 
    return false; 
}); 

我不能这样做$（输入[名称= “条形码”]） 任何想法？

Answer 1

你需要做某事，如：

$('input[type=image]').click(function(){ 
    var image = $(this); 
    var parent = image.parent(); // this will be the fieldset, could also do .closest('fieldset)', if the fieldset is not the immediate parent 
    var neededInput = $('input[name=barcode]', parent); 
    // do something with it 
    return false; 
}); 

或使用siblings() - 方法

$('input[type=image]').click(function (event){ 
    event.preventDefault(); 
    var $image = $(this); 
    var $neededInput = $image.siblings('input[name=barcode]'); 
    // do something with it 
}); 

Answer 2

你的点击函数中，this将是您单击的图像的参考。所以，你可以做

$(this).siblings() 

或

$(this).closest('fieldset').find(...);
