Combobox Object
Get the combobox selected option
var objCombo = eform.get('Combo1');var val = objCombo.getData();
alert(val);
The following example, which is a pull-down list of product name (display value) and product code (key value). The product code is stored as key value which is invisible to end user.
We can use the HTML code to describe the relationship between display and key value:
<select>
<option value=”P0001”>Product A</option>
<option value=”P0002”>Product B</option>
</select>
The combobox will return Product A||P0001 as the value, the first value is the display value, the second one is key value, which are separated by a double pipe.
If you want to get only the display value, you can use getDisplay(), on the other hand, the key value can use getKey(), which will be described in next two tables.
