    Selecting a dropdown option by its text

    So I've got some simple javascript functions to set dropdown selections based on index. But I've also have a field that needs to be selected based on its text (possibly value, but text would be better).

    The current code is really just based around this line:

    document.getElementById("Option3")[myOption1].selected = true;

    and what I'm looking for is:

    document.getElementById("Option3").getIndexByText("TheSelectorText").selected = true;

    Is there a built in function for this? Has anyone implemented it? I searched google and there didn't seem to be any standout answers.

    Thanks!

    There are several ways to do this:-

    Code:
    <form name='myform'>
    <select name = 'list1' id = 'list1' onchange = "rem(this)">
    <option selected value=""> Choose A Fruit</option>
    <option value='Mango'> Mango </option>
    <option value='Apple'> Apple </option>
    <option value='Orange'> Orange </option>
    </form>
    
    <script type = "text/javascript">
    function rem(which) {
    
    var si = document.myform.list1.selectedIndex;
    var txt1 = document.myform.list1[si].text; 
    alert ("Text 1: " + txt1);
    
    var txt2 = document.getElementById("list1").options[si].text; 
    alert ("Text 2: " + txt2);
    
    var txt3 = which.options[which.selectedIndex].text;
    alert ("Text 3: " + txt3);
    }
    
    </script>
