将javascript var转换为java [英] Convert javascript var to java

问题描述

我想转换

var text1 = + location1.lat（）;



到java ...

以便我可以将java值从JSP传递给servlet

I want to convert
var text1 = +location1.lat();

to java...
so that i can pass the java value from the JSP to the servlet

推荐答案

JavaScript和Java是无关的。没有转换。要编写Java等价物，需要什么是位置和 location.lat 对象。你应该理解的主要内容：在JavaScript中，没有类，只有对象。每个对象都有其独立的成员集，并表示为关联容器。在Java中，只有类及其实例，对象。 Java是强类型。而不是var你应该写类型 String 。



这是你需要开始的地方。其余部分取决于我提到的细节。

JavaScript and Java are unrelated. There is no "convert". To write Java equivalent, one would need what are the location and location.lat objects. Main thing you should understand: in JavaScript, there are no classes, there are only objects. Each object has its individual set of members and is represented as associative container. In Java, there are nothing but classes and their instances, objects. Java is strongly types. Instead of "var" you should write the type String.

This is where you need to start. The rest of it depends on the detail I mentioned.
