This time I will bring you a file upload extension made with jQuery. What are the precautions for using jQuery to make a file upload extension? The following are Let’s take a look at practical cases.
Go directly to the code:
/* *jquery.ajaxUpload.js */jQuery.extend({ ajaxFileUpload: function(s) { s = jQuery.extend({}, jQuery.ajaxSettings, s); s.type = "POST"; var f = new FormData(); for (var k in s.data) { f.append(k, s.data[k]); } if (s.fileElementId) { if (!jQuery("#" + s.fileElementId).attr("multiple")) { f.append(s.fileElementId, jQuery("#" + s.fileElementId).get(0).files[0]); } else { var fs = jQuery("#" + s.fileElementId).get(0).files; for (var i = 0; i < fs.length; i++) { f.append(s.fileElementId + "[]", fs[i]); } } } s.processData = s.contentType = false; s.data = f; jQuery.ajax(s); } });
Instructions for use: The principle of the script is to process the data before using $.ajax. The usage method is the same as $.ajax. It just adds fileElementId AttributeUsed to identify the id of the input type="file" node.
