Edit Question
Title
Body
I am working on a project with quite a lot of JQuery in it. The JQuery has a lot of $ signs everywhere, for example $(document).ready(function () { $('input[type=file]').wl_File({ url: '/Admin/PolicyInventory/UploadDocuments', onFileError: function (error, fileobj) { $.msg('file is not allowed: ' + fileobj.name, { header: error.msg + ' Error ', live: 10000 }); } }); ... My question is, what does this dollar sign mean? Why is it used all over the place and how do I understand and interpret it? It reminds me of the scary days of when I was learning Scheme at University and had to put brackets everywhere without knowing why I was doing it.
