将JavaScript局部变量转换为全局变量 [英] Turn a JavaScript local variable into a global variable

问题描述

我有一个JavaScript函数来生成变量.该功能由onclick按钮事件激活.

I have a JavaScript function to generate a variable. That function is activated by an onclick button event.

生成该变量后，我需要将其用作全局变量，以便其他JavaScript进程可以使用该变量.

After that variable is generated, I need to use it as a global variable so that other JavaScript processes can use that variable.

我该怎么做?

推荐答案

您应该能够将变量的值添加到全局 window 对象的属性中:

You should be able to add the variable's value to a property of the global window object:

window.yourVarName = yourVarName;

然后，其他功能只需直接引用 yourVarname 即可访问 yourVarName .无需使用 window.yourVarName .

Then the other functions will be able to access yourVarName simply by referencing yourVarname directly. There will be no need to use window.yourVarName.

但是请记住，通常

However keep in mind that in general, global variables are evil.
