Dynamically change slider start position

Another question is when I tried to use several slider questions: use settimeout function in slider 1 to control the display of slider in next question, I find the slider in the second question cannot be moved.
Qualtrics.SurveyEngine.addOnReady(function()
{
jQuery("#QID47").hide();
setTimeout(function(){jQuery("#QID47").show();}, 5000);
});

QID47 is the second slider question. And its bar cannot be moved. Here is the preview link

Hiding messes with how Qualtrics sets up the slider. Reduce the opacity if you want to hide it from the respondents.

https://community.qualtrics.com/discussion/comment/38358#Comment_38358Thanks. May I ask do you know how to dynamically change the slider's start position? It seems like this.setChoice value doesn't work with the settimeout function.
setTimeout(function(){
this.setChoiceValue(1, 140);
},60000);
Or I can set two questions, but how can I set the second question's slider in the first slider question's javascript? I used the following codes but it doesn't work. QID47 is the second question. I used these scripts in the first question, it says jQuery... is not a function.
var qobj = this;
var qid = this.questionId;
jQuery( "#"+qid ).on('change', function(){
var response = parseInt(jQuery("#"+qid+"\\\\~1\\\\~true-result").val());
jquery("#QID47").setChoiceValue(1, response);
});

it says jQuery... is not a function.
Read your code again till you see why.
SetChoiceValue will not work JQuery, it's an internal Qualtrics method.
this.setChoiceValue(1, 1, 140) should work. But it won't inside the setTimeout due to scoping.

https://community.qualtrics.com/discussion/comment/38385#Comment_38385Is there any way to use setChoicevalue to set subsequent question's choices?
