所以，这里是我的困境：我试图在JQuery中追加到值。所以，我有一个input和我想要的是追加到然后结束一些文本（在这种情况下一个破折号）。我试过.append("-");，但是没有用，因为它将它附加到输入的后面，而不是它的实际值。然后我试着用append.val()这样的东西创意，但我很快意识到你不能那样做。在下面的代码中，在名称input中键入三个字符，然后它将开始混乱。这里是我的代码：追加到JQuery中的值
$(function() {
$("#editorTextInfoName").keyup(function() {
var infoNameTextValue = $("#editorTextInfoName").val();
$("#fullName").text(infoNameTextValue);
});
setInterval(function() {
var infoNameTextValue = $("#editorTextInfoName").val();
var editorTextInfoBoxLength = infoNameTextValue.length;
if (editorTextInfoBoxLength == 3) {
$("#fullName").append("-");
$("#editorTextInfoName").after("-");
}
}, 1);
});table {
display: inline-block;

</html>而且，我其实是.after()为input，不append()。当我尝试.append()时，它没有做任何事情。
我对此的实际目标是，它可以像电话号码input（我只是在名称input上测试它），以便键入三个数字，然后添加短划线。
有什么建议吗？提前致谢！
