トグル幅の変更（jQuery）

Question

iPhoneのメッセージレイアウトを作成しましたが、ボタンをクリックしたときに<div>をトグルします。問題は、この<div>がトグルされたときです。メッセージがすべて一致するように、メッセージwidthを減らす必要があります。私はこのコードを試してみましたが、それはうまくいきませんでした：

$('.my-post .fa-chevron-left').click(function(){ 
 
    $('.controls').toggle(); 
 
      var toggleWidth = $(".message .mine").width() == 430 ? "350px" : "430px"; 
 
     $('.message .mine').animate({ width: toggleWidth }); 
 
});

/* -- POST INFO -- */ 
 
    .info2 { 
 
    width:500px; 
 
    height: auto; 
 
    margin-bottom: 10px; 
 
    height: auto; 
 
    } 
 
    .reblogged img{ 
 
     border-radius:5px; 
 
     vertical-align:middle; 
 
    } 
 
    .reblogged.source img{ 
 
     float:right; 
 
    } 
 
.my-post{ 
 
    overflow:hidden; 
 
    display:inline-block; 
 
    background:#fff; 
 
    padding:5px; 
 
} 
 
.my-post .fa-chevron-left{ 
 
    cursor:pointer; 
 
    vertical-align:middle; 
 
    font-size:12px; 
 
    padding:5px; 
 
    background:#aaa; 
 
    color:#fff; 
 
    border-radius:5px 
 
} 
 
.message i{ 
 
    font-size:12px; 
 
    color:#fff; 
 
    padding:5px; 
 
    float:right; 
 
    border-radius:100%; 
 
    background:#37ce00; 
 
} 
 
    
 
.message 
 
{ 
 
position: relative; 
 
display: inline-block; 
 
width: 440px;

    .reblogged.source{ 
 
    margin-bottom:5px; 
 
    }

display: block; 
 
width: 0; 
 
z-index: 1; 
 
left: -10px; 
 
top: 7px; 
 
} 
 

 
.message.via{ 
 
    background:#dadada; 
 
    color:#000;

.message.via:after{ 
 
    border-color: transparent #dadada;

は、次のように変更しようとすることができます。それは動作しますhere

$('.my-post .fa-chevron-right').click(function(){ 
    $('.controls').toggle(); 
    $('.my-post .fa-chevron-right').toggleClass('active'); 
     var toggleWidth = ($(".message.mine").width() == 430) ? "370px" : "430px"; 
     $('.message.mine').animate({ width: toggleWidth }); 
});
