js controls whether a button can be clicked (can be used) to disable instance

Examples are as follows:

/***
  * Set whether the button can be clicked
  */
function abledDownloadBtn(flag) {
	var $exportChartBtn = $("#exportChartBtn");
	flag ? $("disabled") : $("disabled", "disabled");
}

The above example of js controlling whether a button can be clicked (can be used) disabled is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
