Issue passing string from .js to .jsx file in a function argument

[Sam Marrocco]

I am attempting to pass a single variable from javascript to extendscript in a Premiere extension, but having issues.

If I attempt:

// .js file
csInterface.evalScript('$._PPP_.AssignPaths("QuotedString")');

// .jsx file
$._PPP_ = {
AssignPaths: function (a) {
alert("String Received " + a);
},
};

....Then the information is passed to the jsx file and displayed in an alert dialog. But if I attempt

//.js file
var StringVar = "My Passed Variable";
csInterface.evalScript('$._PPP_.AssignPaths(StringVar)');

....using the same .jsx file, the .jsx file fails to respond.

Is this because the first example is passing a constant and the second example is an actual string? What else would prevent the string from being passed to the extendscript function in this case?

You're not escaping the quote characters, in the string you're passing.
