Javascript - Browser discrepancy?

We tested this JavaScript to maintain selections in the drop downs. It works in safari, but not in chrome. Does anyone has an idea what may cause this?


Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/
 

 
});

Qualtrics.SurveyEngine.addOnReady(function()
{
console.log(jQuery("#"+this.questionId+" select").find("option:eq(0)").text() );
console.log(jQuery("#"+this.questionId+" select").find("option:eq(0)").text() === "");

if ( jQuery("#"+this.questionId+" select").find("option:eq(0)").text() === "")
{ /*Place your JavaScript here to run when the page is fully displayed*/
//jQuery("#"+this.questionId+" sewlect").find("option:eq(0)").text("Select Region").attr("selected","disabled",true);
}
});


Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/
});
