Convert string to variable in Javascript
- by waiwai933
Is there any way to convert a string to a variable in Javascript? Right now, what I have is a script that updates data based on the values of the select box:
<script type="text/javascript">
var a = new Array();
a[0] = 'Name';
a[1] = 'Description';
var b = new Array();
b[0] = 'Name 2';
b[1] = 'Description 2';
function changeSystem(){
var selectedAccount=document.getElementById('selected_option').value;
document.getElementById('name').innerHTML = selectedAccount[0];
document.getElementById('description').innerHTML = selectedAccount[1];
}
</script>
<form method="POST">
<select onchange="changeSystem()" id="selected_option">
<option>A</option>
<option>B</option>
</select>
</form>
<span id="name"></span><br>
<span id="description"></span><br>
selectedAccount is the string of the chosen element in <select>. However, for it to access the array, it needs to be a variable, i.e. a[0] instead of 'a'[0]. What solutions are there to this?
