Why in some case the selected of the iron-page doesn't work?

343 views Asked by At

I made a function to change the "selected" attribute in the iron -page and running, but in some cases the "selected" attribute returns the last value giving the feeling of not changing.

The element

<template is="dom-bind" id="fulltemplate">
    <div id="fullContainer" class="vertical layout flex" hidden>
    <iron-pages id="pages" class="fancy flex center center-justified" selected="{{pageSelected}}" unresolve>

Function

            function goto(i){
        var maintemplate = document.querySelector('#fulltemplate');
        if(i==0){
            document.getElementById("pagesubtitle").removeAttribute("hidden");
            document.getElementById("lefttopbar").removeAttribute("hidden");
            document.querySelector("#iconinfo").removeAttribute("hidden");
            maintemplate.pageTitle = "<%= Resources.GlobalResources.TITLE %>";
        } else if(i==2){
            maintemplate.pageTitle = "<%= Resources.GlobalResources.MASINFORMACION %>";
            document.getElementById("pagesubtitle").setAttribute("hidden", true);
            document.getElementById("lefttopbar").setAttribute("hidden", true);
            document.querySelector("#iconinfo").setAttribute("hidden", true);
        }
        maintemplate.pageSelected = i;
    }

Any ideas to correct the problem ?

Thanks for your time.

You could try using

this.pageSelected

instead of using a property of the maintemplate as 'this' refers to your custom element. Hope that helps.

Another option would be is to select the iron-pages element and directly set the selected property

this.$.pages.selected = i;
