How can I use javascript, to automatically select Option value 2? But I have and as the same id ..
var index = 1; /* option do select*/
document.getElementById("594951-Cor").options.selectedIndex = index;<div id="594951-Cor" name="594951-Cor">
<select id="594951-Cor" name="594951-Cor" class="">
<option value="0">Selecione...</option>
<option value="1">Color 01</option>
<option value="2">Color 02</option>
</select>
</div>After solve the problem with ID's (change the duplicated id's), if you want to select by value, just assign on the select node:
document.getElementById("594951-Cor").value = "2";
assuming that you want to select <option value="2">Color 02</option> and the id of the select node is "594951-Cor".
The "2" is the value of the `option, not the index.
