Examples

The following are some examples to help you get started:

Simple Variables

If I entered myJavaScriptVariable as my key, and testValue as my value, the rule will only pass when it is able to find a global JavaScript variable named myJavaScriptVariable that has a value of testValue.

Configure the Javascript variable rule in the Display Rules of the campaign builder.

Complex Variables

Users can chain together more complex variables, such as an object.

For instance, if my key was globalObj.test1.test2.test3.testVar, the rule will look for window.globalObj, then loop through each section of the JavaScript object to find testVar.

If the string is improperly formed, has a syntax error, or the variable path is incorrect, the rule will fail.
