[SalesForce] Parameterized Custom Label

You can do this using the String.format() method which can provide parameter substitution on your label. The second parameter to this method is a List type and contains your parameters to be substituted.

Label name: MyTestLabel
Label value: Thank you, {0}, for your feedback.


List<String> parameters = new List<String>();
parameters.add('John');

String label = Label.MyTestLabel;
String value = String.format(label, parameters);

You can do it in one line like this as well:

string.format(Label.MyTestLabel, new String[]{'John'});
string.format(Label.MyTestLabel, new List<String>{'John'});

[SalesForce] Javascript custom button throwing error – Undefined is not a function

Map.prototype.set is not completely implemented as a technology in Javascript today. You can read about this in this article about it in MDN.

If you were implementing this as a JS app, you'd probably use a polyfill or a framework to take up the slack between using this and what your browser can support.

In the mean time, the notation you've settled on will work just fine:

fieldNameToIdMap[fieldName]=fieldId
