Description
The FORMAT() function formats the string <expC1> substituting {} parameters with the expressions in the comma-separated list of arguments <exp1> to <expN>. This is similar to C# string formatting.
Also available in JavaScript on desktop, web and mobile. It is particularly useful with the Lianja.evaluate() method when passing parameters to a server-side procedure library from a JavaScript delegate in a web App.
Example
result = format("Hello {0} the number is {1} and the date is {2}", "World", 2020, dtos(date())) // result: "Hello World the number is 2020 and the date is 20200213"
function page1_section1_eg1() { var cnum1 = "5"; var cnum2 = "7"; // Pass as character values for the mylibproc() function in the mylib.prg server-side procedure library var evalstring = format("mylib::mylibproc('{0}','{1}')",cnum1,cnum2); var result = Lianja.evaluate(evalstring); field1.text = field1.text + "\n" + result; }; function page1_section1_eg2() { var num1 = 5; var num2 = 7; // Pass as numeric values for the mylibproc() function in the mylib.prg server-side procedure library var evalstring = format("mylib::mylibproc({0},{1})",num1,num2); var result = Lianja.evaluate(evalstring); field1.text = field1.text + "\n" + result; };
