How to arrange datagrid filtering for different locales?

[aerdem]

We are using easyui for jquery in our application.

In one of the pages I have a datagrid and this datagrid uses clientpaging.

Code:

                  $('#dgTable').datagrid({
                        url:null,
                        autoLoad: true,
                        pageList: [10, 20, 50, 100],
                        clientPaging: true,
                        rownumbers: true,
                        filterMatchingType:'all'
                    });

In this datagrid I added a filter.

Code:

 $('#dgTable').datagrid('enableFilter', [
                         {
        field: 'fieldName',
        type: 'textbox',
        op: ['contains','equal','notequal'],
        options: {
            onChange: function (value) {
                if (value == '') {
                    $('#dgTable').datagrid('removeFilterRule', 'criteriaField');
                } else {
                    $('#dgTable').datagrid('addFilterRule', {
                        field: 'criteriaField',
                        op:  'contains',
                        value: value
                    });
                }
                $('#dgTable').datagrid('doFilter');
            }
        }
    }
                    ]);

It is working for ascii characters but for Turkish specific characters such as ı,İ,Ö,ö,Ü,ü,Ç,ç,Ş,ş,Ğ,ğ it does not work.

Is there any way of using Turkish specific characters for filtering data in datagrid.

Best regards

The filter operators can be overridden to meet your needs.

Code:

$.extend($.fn.datagrid.defaults.operators, {
    contains: {
        text: 'Contains',
        isMatch: function (source, value) {
            source = String(source);
            value = String(value);
            return source.toLowerCase().indexOf(value.toLowerCase()) >= 0;
        }
    }
})

It is working.

I replaced

Code:

toLowerCase()

with

Code:

toLocaleLowerCase('tr-TR') 

for Turkish specific characters.

@jarry Thanks a lot for your help.
