如果條件變成jquery函數

Question

我對jQuery中的條件有點困惑。我想把'if'條件放入一個jQuery函數中。這是對的嗎？還是比這更好的解決方案？

我想把這個方法放到jQuery函數的下面 - 我該如何實現它？

if($(this).attr("id")=='emptys'){ 
    data = { msg : datas } //this is element inside of ajax 
} 
else{ 
    data = { pid : datas } //this is element inside of ajax 
} 

我希望把這個方法在以下功能

<script> 
$(document).ready(function(){ 

    $('.but').click(function(){ 
    var datas = $(this).attr("id"); 
    $.ajax({ 

     type: 'GET', 
     url:"addcart.php", 
     data : { pid : datas }, 
     success:function(result){ 
     $("#div1").html(result); 

    }}); 
    }); 
}); 
</script>

嘗試

$(document).ready(function() { 
    $('.but').click(function() { 
     var data; 
     if (this.id == 'empty') { 
      data = { 
       msg: datas 
      } 
     } else { 
      data = { 
       pid: datas 
      } 
     } 

     $.ajax({ 
      type: 'GET', 
      url: "addcart.php", 
      data: data, 
      success: function (result) { 
       $("#div1").html(result); 
      } 
     }); 
    }); 
}); 

或更好的

$(document).ready(function() { 
    $('.but').click(function() { 
     var data = {}; 
     data[this.id == 'empty' ? 'msg' : 'pid'] = this.id 

     $.ajax({ 
      type: 'GET', 
      url: "addcart.php", 
      data: data, 
      success: function (result) { 
       $("#div1").html(result); 
      } 
     }); 
    }); 
});

<script> 
$(document).ready(function(){ 

    $('.but').click(function(){ 

     var datas = $(this).attr("id"); 
var tempdata; 

    if(datas ==''){// if empty then check by "" 
    tempdata= { msg : datas } //this is element inside of ajax 
    } 
    else{ 
    tempdata= { pid : datas } //this is element inside of ajax 
    } 

    $.ajax({ 

     type: 'GET', 
     url:"addcart.php", 
     data : tempdata, 
     success:function(result){ 
     $("#div1").html(result); 

    }}); 

    });
