Map of additional parameter to submit to remove data source.
Object, default = {}
Adding properties to .postData object will instruct the grid to submit these parameters to the remote data source with each remote request (pull, sort, search, save, delete).
You can defined it during object creation: $('#grid').w2grid({ name : 'grid', url : 'url/to/server', columns: [ { field: 'recid', caption: 'ID', size: '50px' }, { field: 'lname', caption: 'Last Name', size: '30%' }, { field: 'fname', caption: 'First Name', size: '30%' }, { field: 'email', caption: 'Email', size: '40%' }, { field: 'sdate', caption: 'End Date', size: '120px' } ], postData: { param1 : 'value1', param2 : 'value2' } }); Or any time during the run-time: w2ui.grid.postData['myVar'] = 'value';
