when i'm using router, I have Error ("Can't read property 'navTo' of undefined )

[Former Member]

I want to move page when i succeed to check login information. However it didn't work

below is my code.

oModel.read("/LOGIN_INFOSet(USRID='"+USRID+"',PASWD='"+PASWD+"')",null,null,false,

function(oData,repsonse){

  oJsonModel.setData(oData);

  sap.ui.core.UIComponent.getRouterFor(this).navTo("Master" ,{

  currentView : this.getView()

  }, true);

  },

  function(oError){

  alert("Invalid Login Info. Please Check User ID and Password")

  }

  );

When i tried navTo code outside of function, it work.. see below

oModel.read("/LOGIN_INFOSet(USRID='"+USRID+"',PASWD='"+PASWD+"')",null,null,false,

  function(oData,repsonse){

  oJsonModel.setData(oData);

  },

  function(oError){

  alert("Invalid Login Info. Please Check User ID and Password")

  }

  );

sap.ui.core.UIComponent.getRouterFor(this).navTo("Master" ,{

  currentView : this.getView()

  }, true);

I want to use navigation code inside of success function. DO you guys have any Idea

again "this" issue.

just remember   this inside of the nested function is not the this you want.....

var that=this;

oModel.read("/LOGIN_INFOSet(USRID='"+USRID+"',PASWD='"+PASWD+"')",null,null,false,

function(oData,repsonse){

  oJsonModel.setData(oData);

  sap.ui.core.UIComponent.getRouterFor(that).navTo("Master" ,{

  currentView : this.getView()

  }, true);

  },

  function(oError){

  alert("Invalid Login Info. Please Check User ID and Password")

  }

  );

  oJsonModel.setData(oData);

  sap.ui.core.UIComponent.getRouterFor(this).navTo("Master" ,{

  currentView : this.getView()

  }, true);

  }.bind(this), //this should also work

  function(oError){

  alert("Invalid Login Info. Please Check User ID and Password")

  }

  );

Just as an alternative you can use:

jQuery.proxy(function(oData, oResponse){

  oJsonModel.setData(oData);

  sap.ui.core.UIComponent.getRouterFor(this).navTo("Master" ,{

    currentView : this.getView()

  }, true);

},this),
