Javascript“未捕获的TypeError：对象不是函数”

Question

Code is as follows:

function change_course(ref) 
{ 
      var arr = ref.split(/\^/);
  document.getElementById('course').value  = arr[0];
  document.getElementById('course_date').value  = arr[1]; 
}

This will throw an "Uncaught TypeError: object is not a function".

<select name="change_course" class="form-control" onChange="change_course(this.value);">';

Where is wrong

Answer 1

Inline onchange is executed within the same scope as the form element (or inner), and change_course refers to the select element, not to the global function.

To fix this, just give a new value to select 's name attribute, or rename the function.
