VBScript何时用括号

When programming in VBScript, it is important that you follow the rules for using or not using parentheses () in your statements.

You must use parentheses around method arguments if you are calling a method that returns a value and you are using the return value. For example, use parentheses around method arguments if you are returning a value to a variable, if you are using the method in anIfstatement, or if you are using theCallkeyword to call an action. You also need to add parentheses around the name of a checkpoint if you want to retrieve its return value.

Tip: If you receive anExpected end of statementerror message when running a step in your test, it may indicate that you need to add parentheses around the arguments of the step's method.

The following examples show when to use or not use parentheses.

The following example requires parentheses around method arguments, since it returns a value to a variable:

Set WebEditObj = Browser("Mercury Tours").Page("Method of Payment").WebTable("FirstName").ChildItem (8, 2, "WebEdit", 0)

WebEditObj.Set "Example"
