Overview
The JavaScript code in a variable dependency or interval expression is executed when the page is opened and with each change to the page (e.g. entering a variable's data). If a significant amount of JavaScript code is executed, it can reduce the responsiveness of the browser.
Options
Some options to keep the responsiveness of the browser from being reduced:
- Adding a page break between variable groups to increase the speed as only the code on each page is executed (see the Layout tab on the Variable Group Update page).
- Utilizing local variables in place of repeating a condition with a StudyTRAX Variable Code.
- Implementing a global variable to track the current state, thus hiding or disabling will be executed only if the state changes. To implement a global variable, set the global variable before the main function.
A StudyTRAX variable cannot be used as a global variable before the main function.
