JS ドロップダウンボックスの既定値を変更

1.1 Requirement

The last option in the drop-down box defaults to “Select None”. If you pick this option, data will not be filtered in query, that is to say, all options listed in the drop-down box will be picked. So how to make the last option displayed as “Select All”?

2.1 Steps

1）Add a Drop-down Box widget to the parameter pane, customize the data dictionary, add options A, B and C, and check [Allow Null].

The last option in the drop-down list is displayed as “Select None”.

2）Add an After Initialization event to the Drop-down Box widget:

Input the following JavaScript codes:

this.options.name4Empty = "Select All";

2.2 Preview

Save the template and click [Pagination Preview]. The last option in the drop-down list is displayed as “Select All”.
