Passing javascript array to new ExtJS popup window

Question

I have been trying to pass an image array as a parameter to a new ExtJS popup-window. I found this in the below link

Extjs pass in parameters to window on show

But when I tried this in my application, it says undefined. Below is my code.

    this.btnControlPDF = Ext.create('Ext.button.Button', {          
    width: 40,
    height:33,
    border:0,
    disabled : false,
    style: 'margin: 13px 1px 1px 5px;',
    cls : 'icon-button-ControllListButtonPDF',                        
    enableToggle: true,
    toggleGroup: 'AccumulateToolButtons',
    handler : function(myButton) {
        this.reportWindow = Ext.create('Ext.view.ReportExportView');
        this.reportWindow.myExtraParams = { imgArray : imgArray };
        this.reportWindow.show();
        return;
    }
});

Where Ext.view.ReportExportView extends Ext.window.Window

What I want is a way to pass a javascript array variable to new ExtJS popup window and be able to access that variable in the window.

I found HTML5 localStorage.getItem(). Can I use this to store my array?

Thank you! Stu

I hope you want the myExtraParams data to be accessed inside ReportExportView window and also from this.reportWindow. If so try this code.

 this.reportWindow = Ext.create('Ext.view.ReportExportView', {
                       myExtraParams : { imgArray : imgArray } 
                   } });
 this.reportWindow.show();

Way to access myExtraParams from ReportExportView.

Ext.define('Ext.view.ReportExportView', {
    extend: 'Ext.window.Window',
    alias: 'widget.reportwindoww',
    width: 500,
    height: 250,
    layout: 'fit',
    initComponent: function(){
       console.log(this.myExtraParams);
       //You can write the remaining code here.
       this.items = [{
            xtype: 'panel',
            ...............
            ...............
       }];
       this.callParent(arguments);  
    }
 });

But how do I access it in the popup window?

Gilsha Over a year ago

Use initComponent method in ReportExportView definition. With in that, you can just read it like this.myExtraParams. I shall add some code sample if you need.

What I added is var imgsArr = me.myExtraParams.imgArray; in the popup window and it worked! Thank you :)
