如何从输入文本中获取变量值？

Question

I want to take the value from text field to a variable for checking a condition Is it possible in view? I'm using CodeIgniter.

 <input type="text" id="student_gen" name="student_gen"> 

Answer 1

On form submit you can take value in javascript function like:-

var x=document.getElementbyId('student_gen').value;

If you want to do it on entering text immediately then you can call a function on onchange="myFunction()"

and in function you can take value by above method.
