eval Method (Visual Studio - JScript)

Evaluates JScript code and executes it.

function eval(codeString : String)


  • codeString
    Required. A string that contains valid JScript code.


The eval function allows dynamic execution of JScript source code.

The code passed to the eval method is executed in the same context as the call to the eval method. Note that new variables or types defined in the eval statement are not visible to the enclosing program.


For example, the following code initializes the variable myDate to a test date.

var dateFn = "Date(1971,3,8)";
var myDate;
eval("myDate = new " + dateFn + ";");

print (myDate);
