How to call a function from one function in sapui5

[former_member272289]

Hi experts ,

I developed here one oData Get call  that is working fine. But form the success function i just need to call one more function there .

So how to call the other function from the success function.

Plz correct me if i may did wrong anywhere. And send me your guidelines.

I attached my coding here .

press :function () {

  var surl = "service url here ";

     OData.request

                      ({ 

        requestUri:surl, 

                 method: "GET", 

                 headers:

                     {      

       "X-Requested-With": "XMLHttpRequest",

       "Content-Type": "application/atom+xml",

       "DataServiceVersion": "2.0",         

      "X-CSRF-Token":"Fetch"                               

                }       

              },

             function(data, response) { // onSuccess function called when everything is ok

       this.applySearch(); // if i call  the function like this i am getting error like this is not a function like that

    }

},

applySearh : function  () {

}

Thanks and  Regards ,

Damian,

that is because this is out of scope... you can have

var self = this;

right before your ajax call..

then inside the success function:

self.applySearch();  // instead of this

You could set a var to the context of press

var self =  this;

and then in you success function

self.applySearch()

There's also other ways such as jQuery.proxy to do the same.

When you call a function from inside another you need to refer to it with the "this" keyword.

this refers to the javascript file you are inside of.

In your instance you are on the third level.

So you need to set "this inside your main fuction as something else.

Take a look below this is how your code will change (the bold parts)

press :function () {

    that = this;

  var surl = "service url here ";

     OData.request

                      ({

        requestUri:surl,

                 method: "GET",

                 headers:

                     {     

       "X-Requested-With": "XMLHttpRequest",

       "Content-Type": "application/atom+xml",

       "DataServiceVersion": "2.0",        

      "X-CSRF-Token":"Fetch"                              

                }      

              },

             function(data, response) { // onSuccess function called when everything is ok

       that.applySearch(); // if i call  the function like this i am getting error like this is not a function like that

    }

},

applySearh : function  () {

}
