i think problem url in ajax - know since error message states it:
the resource cannot found.
requested url: /qr/@url.action("edit", "camerainfo").
the reason razor syntax not recognized in file.
either set js-variable partial view, like:
<!-- in end of partial view, or wherever referense js-file --> <script type="text/javascript"> var myjsurl = '@url.action("edit", "camerainfo")'; </script> //in js-file, assuming referensed partial view $.ajax({ type: "get", url: myjsurl, ... or type hand (the easiest solution):
$.ajax({ type: "get", url: '/camerainfo/edit', ... i should there no need keep writing $(document).ready before each method/call. once, , put code within scope of that.
edit:
also, you're binding 2 change events same textbox (#qr-value). merge code , keep 1 event:
$(document).ready(function () { $('#qr-value').on('change', function () { var string = $('#qr-value').val(); if (~string.indexof('job')) { var num = string.match(/\d+/g); $("#qr-number").val(num).change(); $("#second").show(1000); } else { $("#qr-number").val("") $("#second").hide(500); } $.ajax({ type: "get", url: '/camerainfo/edit', data: { id: $('#qr-number').val() }, success: function (response) { $('#sample').html(response); }, error: function (response) { if (response.responsetext != "") { alert(response.responsetext); alert("some thing wrong.."); } } }); }); });
