[khoanguyenlio]

i got an issues in IE 11, when I use my custom element. It's normal in chrome but in IE11 I got this problem

Failed to open data:text/javascript;charset=utf-8, (function () {

[khoanguyenlio]

Just syntax, i declare a function lkie _renderClosed(){} -> should use _renderClosed: function(){}.
Still work in Chomre but not for IE/FF

@khoanguyenlio can you post the JS from your component here?

Also sometimes stackoverflow is a better place to ask these questions to get general debugging tips.

@samccone thank you :+1:
<script>
`Polymer({
is: 'spas2-date-picker',

    properties: {
        value: {
            type: Array,
            observer: 'bindValueChanged'
        },
        minDate: {
            type: Array
        },
        maxDate: {
            type: Array
        },
        inValid: {
            type: Boolean,
            observer: 'bindInValidChanged'
        }
    },

    showDatePickerDialog: function () {
        this.$.spas2dialogDatePicker.open();
    },
    onChangeDatePicker() {
        this.$.spas2dateField.value = new Date(this.$.spas2picker.date).format('yyyy-mm-dd');
        this.value = this.$.spas2dateField.value;
    }

</script>

i got this error cuz -> onChangeDatePicker() {} is wrong. -> onChangeDatePicker: function() {

if you found out, maybe close the issue?

I wonder what was the issue? Having similar error in IE11 now.

I have a similar issue in IE11 - any ideas?

[rozzamozza]

The problem (which happened to me too) can be fixed by chnaging:
onChangeDatePicker(){
to:
onChangeDatePicker : function(){

I am also having this issue, but the errors are coming from Polymer code files like lib/utils/case-map.html.js and /lib/elements/dom-module.html.js. I am just trying to get the basic CustomElement example to work in IE 11. Is anyone else seeing this?
