Example: Selecting all of the entries in a list box that is on a webpage
The methods and properties for changing the selected entry on multiselect HTML list boxes only allow you to select one entry. There is no simple way to perform a Select All action.
To work around this limitation, use the ExecuteScript method off of the webpage. To do this, your list box must meet these requirements:
- It must be an HTML Select element
- It must have an ID
If you run the following script in an ExecuteScript method call, the system selects all of the list box items:
var listbox = document.getElementById("<i>elementid</i>");
var options = listbox.options;
for (var index = 0; index < options.length; index++)
options[index].selected = true;
In the example script, replace
<i>elementid </i>with the ID of your list box.
For more information on the ExecuteScript method, see Web Page Properties, Methods, and Events.
