extjs' passing extra parameters for grid due using pagination buttons

Question

I have a problem. I have getAllJobsControllerUrl() function which return url with specific parameters:

        proxy: new Ext.data.ScriptTagProxy({
                      url: getAllJobsControllerUrl(),
                      method : 'GET'
        })

And all code concerned with grid:

   var store = new Ext.data.JsonStore({
        root: 'jobs',
        totalProperty: 'totalCount',
        fields: [ 

                  {firld description}],

        proxy: new Ext.data.ScriptTagProxy({
                      url: getAllJobsControllerUrl(),
                      method : 'GET'
        })
    });


    var grid = new Ext.grid.GridPanel({
        id: 'mainGrid',
        el:'mainPageGrid',
        autoWidth: true,
        store:store,
        cm:cm,
        viewConfig:{
            forceFit:true
        },
        width :1000,
        height:500,
        loadMask:true,
        frame:false,

        bbar: new Ext.PagingToolbar({
            id : 'mainGridPaginator',
            store:store,
            pageSize:10,
            displayMsg: '{0} - {1} of {2} results',
            emptyMsg:'No results found for your search criterion',
            displayInfo:true
        }),

        tbar:tabBar
    });

The Question/Problem: When I make Ajax Request with getAllJobsControllerUrl() and then reload store, I'm sending to server proper request string.

But when I'm trying to use pagination buttons ('<-' and '->' in the bottom of grid), It seems I'm sending the request string which has been formed once on first access and then it don't modify.

F1 :)

Added:

function getAllJobsControllerUrl() {
    return '../../statusList/getJobs/search-' + searchType + '-' + searchValue + 
            '/sort-' + sortName + '-' + sortOrder + 
            '/filterSd-' + filterSubmittedDate +
            '/filterSt-' + filterStatus +
            '/filterUn-' + filterUserName +
            '/filterJn-' + filterJobName
}

Are you sure that you are sending the right parameters for pagination? start, limit, total? — It Grunt, Jun 19 '11 at 23:32
@It Grunt: when I pressing pagination buttons, total, count and limit passing correctly — davs, Jun 20 '11 at 07:10

Thanks everybody for trying help me. I have migrated my code to extjs 4.0 and decided to make extra parameters, which are now working for me

            store : store = new Ext.data.JsonStore({
                fields : [....],
                ....
                listeners: {
                    'beforeload': function(store, options) {
                        store.proxy.extraParams.param1='val1';
                        store.proxy.extraParams.param2='val2';
                    },

So, in result I'm getting follow request:

http://myip:8080/myproject/statusList/getJobs?param1=val1&param2=val2

Good luck!

You need to update the proxy with new url before load. Best way would be to use the store's beforeload event.

Change your store definition to


var store = new Ext.data.JsonStore({
    root: 'jobs',
    totalProperty: 'totalCount',
    fields: [ 

          {firld description}],

proxy: new Ext.data.ScriptTagProxy({
              url: getAllJobsControllerUrl(),
              method : 'GET'
}),

listeners:{
    beforeload:function(store, options){
        store.proxy.setUrl(getAllJobsControllerUrl());
    }
}


});

store.proxy.setUrl() throws an error ( no such method). But, store.proxy.url = getAllJobsConrollerUrl() in this case don't help — davs, Jun 22 '11 at 04:26
