       var username.value=Observable("");
       var password.value=Obserable("");

      function loginPostData() {
        var myVar={
        fetch('', {
   method: 'POST',
   headers: { "Content-type": "application/json"},
   body: JSON.stringify(myVar)
}).then(function(response) {
   status = response.status;  // Get the HTTP status code
   response_ok = response.ok; // Is response.status in the 200-range?
   console.log("Response: " + JSON.stringify(response));
   return response.json();    // This returns a promise
}).then(function(responseObject) {
   // Do something with the result
   console.log('the API said: ' + JSON.stringify(responseObject));
}).catch(function(err) {
   // An error occured parsing Json
   console.log('Error : the API said: ' + JSON.stringify(responseObject));

Where is this JavaScript tag in relation to the rest of the code?


It’s exist in the MainView.ux file .

Thanks .

Here :

you could find the all project .

You have typos in your javascript: require"FuseJS/Observable" should be require("FuseJS/Observable"); and there’s a missing “v” in Obserable(""); a few lines below.

Fixing those two gave me the expected HTTP response when logging in.

Also, I strongly recommend that you migrate your project to the latest version of Fuse


I fixed my code , and installed the latest version 0.21. but i have the same problem

clicked don’t work .

Then I recommend that you try to create a minimal test case which reprodues the issue with as little code as possible, to make it easier to debug.


  • What platform(s) are you testing on
  • And which exact behavior are you expecting when you click on the button? (As mentioned I got an HTTP response)
