asp.net - Upload file using jQuery and post it to Controller -

-

i'm wondering if possible @ upload file posting controller action in asp.net mvc. dialog upload form dynamically generated , inside jquery dialog in case.

i'm aware of file input element i'm not sure how send file controller action, not sure how set action parameter

your action should this:

[httppost] public actionresult upload(httppostedfilebase file) {    if (file.contentlength > 0) {     var filename = path.getfilename(file.filename);     var path = path.combine(server.mappath("~/app_data/uploads"), filename);     file.saveas(path);   }    return redirecttoaction("index"); }

taken :http://haacked.com/archive/2010/07/16/uploading-files-with-aspnetmvc.aspx/

then using jquery dialog file upload:

$dialog.dialog("option", "buttons", {     "save": function () {         var dlg = $(this);         var formdata = new formdata($("#" + formname)[0]);         $.ajax({             url: /controller/upload,             type: 'post',             data: formdata,             processdata: false,              contenttype: false,             success: function (response, textstatus, xhr) {             ...                 }             },             error: function (xhr, status, error) {                 ....             }         });     },     "cancel": function () {         $(this).dialog("close");         $(this).empty();     }  });

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

is there solution disable node in javafx without disabling children ? want disable nodes in pane except 1 of them dynamically. tried solution , other solutions doesn't work , think has bad performance! node.getparent().requestfocus(); for(int i=0 ; i<pane.getchildren().size() ; i++){ if( !pane.getchildren().get(i).isfocused()){ pane.getchildren().get(i).setdisable(true); } } edited: also tried solution: added transparent pane main pain , add special node . doesb't work complex components because should keep sizes , locations of it's children ! i want user interact 1 node of whole scene , other nodes should disable . the current javadoc of booleanproperty disableproperty() of node says: "...... setting disable true cause node , subnodes become disabled ....... https://docs.oracle.com/javase/8/javafx/api/javafx/scene/node.html#setdisable-boolean- https://docs.oracle.com/javase/8/javafx/api/javafx/scene/node.h...
