如何在 get 语句中传递 javascript 变量？

Question

I want to pass the variable testVar into the get statement so I can compare the value of it with the PHP variable param. When I log testVar in the console, I get undefined. I am very new to programming so any help would be appreciated.

var testVar= "hello"
;

$.get('schools.php', function (param) {
    console.log(testVar) //This gives me 'undefined'
    if (param[1]== testVar){
      console.log("it is working!")
    }                   
})

Answer 1

This is a scope problem. The variable inside the function is different from the global, so, therefore, it gets reassigned inside your function.
