jqgrid中如何清除网格参数？

如果我设置了 jqgrid 参数，然后我再次想用新参数重置参数，而不附加旧参数，我该如何实现？

举例来说：

Step 1: jQuery("#list").setGridParam({url:"testJsp.jsp",
                    mtype: "POST", 
                    postData:{xyz: '23fd', 
                              asd: 'were' }
                    });

Step2: jQuery("#list").setGridParam({url:"testJsp.jsp",
                mtype: "POST", 
                postData:{ert: 'trer', 
                          ghj: 'rew' }

                });

现在，当我这样做时，到“第 2 步”结束时，我总共有 4 个参数，包括“第 1 步”中的参数。但我不想要这个。在“第2步”之后，我只想获得“第2步”的参数。

有没有办法清除“步骤1”和“步骤2”之间的网格参数？

If I set the jqgrid parameters and then I again want to reset the parameters with new ones, without the old parameters being appended, how do I achieve that?

Lets say,for example:

Step 1: jQuery("#list").setGridParam({url:"testJsp.jsp",
                    mtype: "POST", 
                    postData:{xyz: '23fd', 
                              asd: 'were' }
                    });

Step2: jQuery("#list").setGridParam({url:"testJsp.jsp",
                mtype: "POST", 
                postData:{ert: 'trer', 
                          ghj: 'rew' }

                });

Now when I do this, by the end of "Step 2" I have a total of 4 parameters, including the parameters from "Step 1". But I don't want this. After "Step 2" I just want to have the parameters of "Step 2".

Is there a way to clear the grid parameters between "Step 1" and "Step 2"?

在设置新值之前将 postData 设置为 null。如果 url 和 mtype 没有更改，则无需重新定义它们。

jQuery("#list").setGridParam({postData: null});

jQuery("#list").setGridParam({postData: 
   {ert: 'trer', 
    ghj: 'rew' }
});

Set postData to null before setting the new value. You don't have to redefine values for url and mtype if they're not changing.

jQuery("#list").setGridParam({postData: null});

jQuery("#list").setGridParam({postData: 
   {ert: 'trer', 
    ghj: 'rew' }
});

表达式 jQuery("#list").jqGrid('getGridParam', 'postData') 为您提供对表示 postData 的对象的引用 >。因此，您可以像使用对象一样使用它，并在需要或不再需要时添加或删除属性：

var myGrid = jQuery("#list"),
    myPostData = myGrid.jqGrid('getGridParam', 'postData');

// next two lines are equivalent to
//    myGrid.jqGrid('setGridParam', 'postData', {xyz: '23fd', asd: 'were' });
myPostData.xyz = '23fd'; 
myPostData.asd = 'were';
...
delete myPostData.xyz;
delete myPostData.asd;
...
// next two lines are equivalent to
//    myGrid.jqGrid('setGridParam', 'postData', {ert: 'trer', ghj: 'rew' });
myPostData.ert = 'trer'; 
myPostData.ghj = 'rew';
...

The expression jQuery("#list").jqGrid('getGridParam', 'postData') get you the reference to object which represent the postData. So you can work with it like with an object and add or delete properties whenever you need or not more need these:

var myGrid = jQuery("#list"),
    myPostData = myGrid.jqGrid('getGridParam', 'postData');

// next two lines are equivalent to
//    myGrid.jqGrid('setGridParam', 'postData', {xyz: '23fd', asd: 'were' });
myPostData.xyz = '23fd'; 
myPostData.asd = 'were';
...
delete myPostData.xyz;
delete myPostData.asd;
...
// next two lines are equivalent to
//    myGrid.jqGrid('setGridParam', 'postData', {ert: 'trer', ghj: 'rew' });
myPostData.ert = 'trer'; 
myPostData.ghj = 'rew';
...
