在javascript中将var转换为int作为java [英] Convert var to int as java in javascript

问题描述

在javascript中我可以将值转换或传递给var a =<<％b％> ;;

但我无法转换<％b％> = var获取错误



我的尝试：

in javascript i can convert or pass values to var a= <<%b%>;
but i cant able to convert <%b%>=var its getting error

What I have tried:

 for(var a=1;a<=intTextBox ;a++)  
 { 
var doct_id = parseFloat(array[a-1]);


<%int b;%>
<%b%> = doct_id;
}

推荐答案

没有这样的事情。这个问题毫无意义，因为 var 是关键字，而不是数据类型，并且没有int这样的东西。没有什么可以转换的。也许您需要了解JavaScript类型系统，它基于一种松散型范例。请特别注意：

JavaScript数据类型和数据结构 - JavaScript ，

typeof - JavaScript 。



无论如何，假设您在代码中使用的变量按预期初始化，它会为您提供正确的代码;例如，它可能是

There is no such thing. The question makes no sense, because var is a key word, not a data type, and there is no such thing as "int". There is nothing to convert. Perhaps you need to understand JavaScript type system, which is based on a kind of "loose-type paradigm". Please see, in particular:
JavaScript data types and data structures — JavaScript,
typeof — JavaScript.

Anyway, assuming the variables you use in your code are initialized as expected, it gives you correct code; for example, it could be

var array = [1.1, 2.2, 3.3];
var intTextBox = array.length;
// intTextBox is redundant,
// you could use array.length in the loop:

for (var a = 1; a <= intTextBox; a++) {
   var doct_id = parseFloat(array[a - 1]);
   doSomething(doct_id);
}

换句话说，我没有看到你的代码片段有任何问题;你只是没有解释它的背景。
