要在确认框中更改按钮标签，请尝试运行以下代码。该代码使用JavaScript库jQuery和CSS创建一个带有不同于标准确认框的按钮标签的确认框-
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js">
</script>
<script>
function functionConfirm(msg, myYes, myNo)
{
var confirmBox = $("#confirm");
confirmBox.find(".message").text(msg);
confirmBox.find(".yes,.no").unbind().click(function()
{
confirmBox.hide();
});
confirmBox.find(".yes").click(myYes);
confirmBox.find(".no").click(myNo);
confirmBox.show();
}
</script>
<style>
