当jfiddle语言是javascript而不是javascript 1.7时,此代码可以在Jfiddle中运行。它也没有在实际网站的文本框中放置任何内容。它应该接受用户输入并返回一个数字。我是网络开发的新手,所以任何帮助都会很棒。
$('#teambtn').click(function() {
var Domain = $("#domain option:selected").val();
var Mobile = $("#Mobile option:selected").val();
var Pages = document.getElementById("pages").value;
Domain = Domain * 1;
Mobile = Mobile * 1;
Pages = Pages * 1;
var Result = ((10 + (Pages*5)) * Mobile) + Domain;
Result = Result + '';
$('textarea#team').text(Result);
});
