Question

我无法理解。。当我点击具有唯一ID的特定事件时，我需要获取该ID的名称，但是目前我获得了所有ID的同名信息。有关说明，请参阅以下注释

＆＃13;

function update(){
//this is the array of database values
dbvalues = dbvalues.split("~"); //dbvalues[i+0], dbvalues[i+1]....


//I have a label which have values form database
var  dblabel = '<br/><label class="addevents" id="' + dbvalues[i+3] + '">'+dbvalues[i+2]+ " " + dbvalues[i+4] +'</label>';

//this variable holds all the event name that are in database.
var g =dbvalues[i+2];//eg: meeting, lunch, dinner

//now this is the the real function, I am getting ID of the label, when I click  on particular ID it needs to show name of that particular ID, but currently whichever event I click it shows same name for all the IDS.
var el = document.getElementById((dbvalues[i+3]));
				
el.onclick = function () {
     alert(g); //it is showing same name for all the ID'S clicked. 
};

};

您无法使用此方式使用Var g值因为可以更改所有时间变量值。因此，当您单击元素时，元素在那时只有最后添加的值可用于所有var g所以您可以为所有元素获得相同的值。在那个时候如果你想这样做你可以尝试使用 Html data attr 这样

        public Class1()
        {
           products.add(new Product("Big Phone", 200.00, PHONE));
           products.add(new Product("Small Phone", 50.00 , PHONE));        
           products.add(new Product("Aftermarket Charger", 10.00, CHARGER));
           products.add(new Product("Original Charger", 20.00, CHARGER));
           products.add(new Product("Case", 20.00, ACCESSORIES));
           products.add(new Product("Other Accessories", 60.00 , ACCESSORIES));
        }
      public LinkedList<Product> products(Category category){
            for (Product product : products)
                if (product.matches(category))
                    return products;
            return null;             
        }

你的点击代码看起来像这样

 Public class Class4 {
    public class createOrder { 
    System.out.print.ln("Creating new order")
    } 
    }

显示正在点击的活动的数据
