    Default PagingToolBar: extension - add public method - goToPage()

    PagingToolBar: extension - add public method - goToPage()


    I didn't know what to call it, so i called it 'CustomToolBar'. i looked at the source, didn't see anything like it.

    PHP Code:
    // Create user extensions namespace (Ext.ux)
    Ext.namespace('Ext.ux');

    Ext.ux.CustomToolBar = function(config) {
        
    // call parent constructor
        
    Ext.ux.CustomToolBar.superclass.constructor.call(thisconfig);
     

     
    // extend
    Ext.extend(Ext.ux.CustomToolBarExt.PagingToolbar, {
        
    goToPage : function (pageNum) {
            var 
    this.getPageData();
            
    pageNum Math.min(Math.max(1pageNum), d.pages) - 1;
            
    this.doLoad(pageNum this.pageSize);
        }
    }); 
    // end of extend 
    usage:
    PHP Code:
    var paging = new Ext.ux.CustomToolBar ({your config data});
    // Jump to page
    paging.goToPage(int);

    If the only reason you're extending the PagingToolbar is to add a new method to it, why not just use an override?

    Code:
    Ext.PagingToolbar.override({
        goToPage : function (pageNum) {
            var d = this.getPageData();
            pageNum = Math.min(Math.max(1, pageNum), d.pages) - 1;
            this.doLoad(pageNum * this.pageSize);
         }
    });
