jQuery / Javascript按钮文本更改（编辑！）

Question

EDIT!

I have a single button called "pc3LoadSELECT" that opens up a pop up with a new button called "loadCol_1" and loadCol_1 gets up to 150 options from local_storage.

What I need to work out is how to get "pc3LoadSELECT" label SELECT to change to whatever value is present in loadCol_1.

EG: If I choose 150 then the label SELECT will replace with 150.

The 2 set's of code I have played around with are:

$('a[dsid="pc3FitmentSELECT"]').text("");

&

var listOfLabels = ['loadCol_1'];

function getRandomLabel()
{
    return listOfLabels[Math.floor(Math.random() * listOfLabels.length) + 1];
}

$('a[dsid="pc3LoadSELECT"]').text("");

I will admit, in this 1 task I have been set, I am absolutely blind. So any help in attempting to work out or try to workout what is needed.

The data present isn't random and I shall attach an image which will show the range of options possible for this 1 button in the popup (a small sample).

Please advise?

List of Possible Options

Answer 1

I created an example of a button that gets its value from an array. Every time you open the popup you should set the button value from a list of options.

for that i created the function getRandomLabel();

hope that helps :)

 var listOfLabels = ['opt-1', 'opt-2', 'opt-3', 'opt-4', 'opt-5', 'opt-6']; function getRandomLabel() { return listOfLabels[Math.floor(Math.random() * listOfLabels.length) + 1]; } $('.randomize-label').click(function() { $('.btn1').html(getRandomLabel()); });
