将javascript变量值传递给c++变量

Question

I'm using g++ to edit an html webpage, so how do I pass a javaScript variable value to c++ variable by using a javaScript function? eg

function convert(val){//conversion
}

Answer 1

g++ is a compiler. It can't edit websites.

But if you manage to pass a variable from JavaScript to C++, you need to validate the content of the variable in C++, not in JavaScript. This is because JavaScript treats variables differently than C++ compilers.
