How to execute javascript for each item in a repeat?

formatters are essentially Javascript functions that run on values to convert them (such as formatDate(), .sort(), .trim() etc.). You can create your own with the function you have written.

Creating Custom Formatters (PHP and client-side)

I have been trying to supplement the native formatters in Wappler and found that most things can be added by using custom formatters. What I found, though was the technique for this was hidden in answers to specific questions so thought a short tutorial may help some: Server-side (php) In dmxConnectLib/lib/formatters create a file, call it something like customformatters.php (do not alter the native files as it could be overwritten with updates) Add the relevant code: the function name shoul…

Then you could apply a .setlc() formatter, using your code, to the values which would return the true/false/other value you have coming back from the formatter.

The only consideration is if it matters that it keeps evaluating over and over. Formatters run over and over to apply the format to any updated value. @mebeingken and @patrick were looking at limiting execution if you just wanted to run it when the value was updated:

Formatters that only run when the triggering value changes

Today, we have these great formatters to display values/string in a different way. However, these formatters seems to constantly (re)run even if the base value/string has not changed. For example, if you create a custom formatter that simply console logs and returns you can see if just keeps running. dmx.Formatter('string', 'tester', function (str) { console.log('formatter run'); return str; }); [Screen Shot 2021-09-13 at 11.36.17 AM] No big deal until there are dozens/hundreds of m…
