1、getElementById() getElementById()可以访问DOCUMENT中的某一特定元素,顾名思义,就是通过ID来取得元素,所以只能访问设置了ID的元素。比如说有一个DIV的ID为docid:程序代码<div id="docid"></div>,那么就可以用getElementById("docid")来获得这个元素。 2、getElementsByName() 这个是通过NAME来获得元素,...

elementui tree组件 getNode分析 当我们调用getNode方法实际执行的是上图的方法,首先判断了data对象,是传入了key值还是node对象,如果传入的是一个node对象则可以直接返回数据,接着判断传入的data是不是一个对象,如果是key值就从nodesMap中找对应的数据,如果是一个对象则执行getNodeKey,这里的this指向是TreeStore,存储...
Java可以通过反射机制将字符串转换为对象并添加变量。反射是Java提供的一种机制,可以在运行时动态地获取类的信息并操作类的成员。 要实现从字符串向对象添加变量,可以按照以下步骤进行: 获取类的Class对象:使用Class.forName()方法获取字符串对应的类的Class对象。例如,如果字符串是"com.example.MyClass",可以使用以下...

If you are using java8, filters(in lambda expression) is a good option. Stream<Variable> outputList = varList.stream().filter(val -> val.getId() ==1); outputList will contain only Variable objects with Id 1. First element can be taken from that list if it is not empty. Ref: ht...

Hashmap is an essential part of Java and gives us the power of flexibly work on our data by using the key-value pair method. The value is attached to the key, and we can find the value using its key very easily. But what if we want to fetch the key from a value?
