Long time no new entry. 🙂 Internship is keeping me very busy. In this blog entry I’ll show you how to select a drop down option by specifying its index number.
document.getElementById("selectionDD").selectedIndex = 0;
The HTML code:
<select id="selectionDD" name="selectionDD">      <option value="one">One</option>      <option value="two">Two</option>      <option value="three">Three</option> </select>
selectionDD is the id of the
<select> tag. The value 0 represents the index number of the option that we want to be selected, and will select the first option in the selection. Note that the index numbers start with 0, not 1.
