jqgrid中的预选过滤器(多选) [英] Pre-select filters in jqgrid (multi-select)

问题描述

以此示例为例( http://www.ok-soft-gmbh .com/jqGrid/SimpleLocalGridWithSearchingToolbarMultilpe.htm )( Excel像在jqgrid中进行过滤一样)

是否有从头开始设置过滤器参数的方法?例如，在通过...发货"列中，我希望选中"TNT"和"Intim"，而未选中"FedEx".

我认为可行的一种解决方案是ship_via

if(id == 'gs_ship_via'){ 
                        _.forEach($options, function(option){
                            if(option.value != 'FexEx'){
                                option.selected = true; 
                            } else {
                                option.selected = false;    
                            }
                        });
                    }

此后，我遇到的问题是它不会更新网格中的数据.因此，在加载复选框后，我需要一种不同的方式来设置复选框，以更新网格的方式.

我假设您需要包括change事件($("#gs_ship_via").change();)的触发器或调用triggerToolbar($grid[0].triggerToolbar();)的触发器.确切的解决方案可能在很大程度上取决于您进行更改的位置.如果要在初始化多重选择后对例如 的多重选择选项进行更改，则可能会看到错误的多重选择选项，并且可能需要调用refresh.

请参见该演示，其显示的结果类似于

可能可以修改解决方案来设置多个值，使用答案中的想法，但与目前相比，这需要花费更多时间. :-(

Taking this example (http://www.ok-soft-gmbh.com/jqGrid/SimpleLocalGridWithSearchingToolbarMultilpe.htm) from this question (Excel like filtering in jqgrid)

Is there a way to set the filter parameters from the start? For example, in the 'Shipped via' column, I would want 'TNT' and 'Intim' to be checked, leaving 'FedEx' unchecked.

One solution I thought was viable is to ship_via

if(id == 'gs_ship_via'){ 
                        _.forEach($options, function(option){
                            if(option.value != 'FexEx'){
                                option.selected = true; 
                            } else {
                                option.selected = false;    
                            }
                        });
                    }

The problem I run into after that is that it doesn't update the data in the grid. So, I need a different way to set the check box after it's loaded in a way that will update the grid.

解决方案

I suppose that you need to include trigger of change event ($("#gs_ship_via").change();) or to call triggerToolbar ($grid[0].triggerToolbar();). The exact solution can heavy depend on the place where you made the changes. If you would make the changes of multi-select options for example after initializing of multiselect you could see wrong multiselect options and you could require to call refresh.

See the demo which displays the results like

Probably one can modify the solution for setting multiple values which uses the idea from the answer, but it will take a little more time as I have currently. :-(
