傳遞值爲成功函數

Question

是否可以傳遞值爲success函數？

function updateData(data_type){ 
    var current_url = "myUrl"; 
    var opc = data_type; 
    var dataset = []; 
    $.ajax({ 
    data : {'type': opc}, 
    url : current_url, 
    type : 'get', 
    success: function(data){ 
     update(data) 
    } 
    }); 
    console.log("update: " + data_type); 
} 

裏面的success功能我要訪問我的data_type變量，我路過參數。

這可能嗎？

Answer 1

直接使用它，就像這樣：

function updateData(data_type){ 
    var current_url = "myUrl"; 
    var opc = data_type; 
    var dataset = []; 
    $.ajax({ 
    data : {'type': opc}, 
    url : current_url, 
    type : 'get', 
    success: function(data){ 
     update(data, data_type); 
    } 
    }); 
    console.log("update: " + data_type); 
}

function updateData(data_type) { 

    var current_url = "myUrl"; 
    var opc = data_type; 
    var dataset = []; 

    $.ajax({ 
    data : {'type': opc}, 
    url : current_url, 
    type : 'get', 
    success: function(data){ 
     // `data_type` is available here, use as needed. 
     // You can pass it to other functions inside this one as well, 
     // i.e. the function below could be `update(data, data_type);`. 
     update(data); 
    } 
    }); 

    console.log("update: " + data_type); 

}
