javascript - The onclick event does not work for options

Following is my code which works fine in firefox but not in chrome. Kindly let me know how to solve this issue. The main idea is to call a js function based on the selected value of select box:

<select onselect="question_type(this.value);" name="qtype" id="qtype" class="form-control input-lg" required>
    <option value="">-- Select question type for this quiz --</option>
    <option onclick="question_type(this.value);" value="mcq">1) MCQs</option>
    <option onclick="question_type(this.value);" value="tf">2) True/False</option>
</select>

options don't fire mouse events in chrome.

For a select element you'd use the onchange event on the select itself, and the value of the select will always be the same as the selected option

<select onchange="question_type(this.value);" name="qtype" id="qtype" class="form-control input-lg" required>
    <option value="">-- Select question type for this quiz --</option>
    <option value="mcq">1) MCQs</option>
    <option value="tf">2) True/False</option>
</select>

with jQuery it would be

$('select').on('change', function() {
    var selected = this.value;
});
