How to get text box value in JavaScript

by

Your element does not have an ID but just a name. So you could either use getElementsByName() method to get a list of all elements with this name:

var jobValue = document.getElementsByName('txtJob')[0].value  // first element in DOM  (index 0) with name="txtJob"

Or you assign an ID to the element:

<input type="text" name="txtJob" id="txtJob" value="software engineer">
