@Noor-gv8ec 5 лет назад

There's no need to write an if statement. You can also add them on this way. Here's the code. function myFunction() { var x = parseInt(document.getElementById("b1").value); var y = parseInt(document.getElementById("b2").value); var z = x + y; document.getElementById("demo").innerHTML = z; }

@1BestCsharpblog 5 лет назад

you need if statement to know what operation to do

@onlineworkwear941 5 лет назад

How do you set n2 to be a fix numeric value? So for example if you wanted to calculate the price of something: n1(qty) x n2($2.50)

@1BestCsharpblog 5 лет назад

you can add "readonly" to your input like this -- or use a span instead

@madhavanmadhavan7786 5 лет назад

whats happen when i give else part after the if part?

@erosveizi91 7 лет назад

Cant Understand only one thing and it looks very strange. If i save the result in a variable inside the function: var result=document.getElementById('result').value; result=num1+num2; the result wont show in its textbox. But if i write: var result=document.getElementById('result'); result.value=num1+num2; then everything is alright. Can you please explain me this???

@1BestCsharpblog 7 лет назад

In " var result=document.getElementById('result').value; " the "result" have the value of the textbox [ Ex: 1,2,999, 2348.................. ] and in " var result=document.getElementById('result'); " the "result" have the reference of the textbox so you can set the value to the textbox using the "result" var (result.value=num1+num2;)

@Theelderscrollsftw94 6 лет назад

Do you have the result outside the function? Because then it would be unable to pick up the variable, because if you write it inside, then it will ofcourse only count for inside the function and not out of it. Unsure of what's your problem as I cannot see the code.

@Atrophyiies 5 лет назад

@YoungFuji-ct8hf 5 лет назад

Would a switch statement work with all this?

@spiderweb3324 9 месяцев назад

off course it will work. He was made this with if else and on click function, you can do it with addEventListener grab value of operators and then with switch manipulate with numbers.
