Can the drop-down box change event be called during initialization?

  node.js, question

A drop-down list, value change calls jquery’s Change event to request ajax data
I now want the page to get ajax data under an option when loading, and want to realize such a function. is there any good way?

When the page is loaded, use jquery selector to find the corresponding option and click it.

$(function(){
 $(option).click();
 })
