Question

How do I browse to upload a file using Dojo? See the code below:

 dojox.io.xhrMultiPart({
              url: "http://localhost:8080/myWebService",
              handleAs: "xml",
              form: dojo.byId("myForm"), 
              load: function(data){ processRequest(data);},
              error: function(error){ processError(error); },
              backButton: function() { 
              },
              mimetype: "text/xml"         
        });

Now which code do I have to append to the above code to upload a file?

Answer 1

I use dojox.form.Uploader , which will enable you the “Browse” functionality.

<input name="file" multiple="false" type="file" dojoType="dojox.form.Uploader" label="Select Class File" id="uploadedfile" />

I use dojo.io.iframe.send to upload file.
Then on the submit button of the form, I use following function to post,

function addSwitchType(){
    var td = dojo.io.iframe.send({
        url: switchType_Add_URL,
        form: formName,
        method: "post",
        preventCache: true, 
        handleAs: "json",
        load: function(response, ioArgs){

            },
        error: function(response, ioArgs){

            }
    });
}
