用静态数据加载jqGrid的最佳方法? [英] Best way to load jqGrid with static data?

问题描述

我们通过创建JSON字符串将10行静态数据加载到jqGrid中:

We load 10 rows of static data into our jqGrid by creating a JSON string:

var d = "{\"page\":1,\"records\":10,\"total\":1,\"rows\":[" +
                "{\"id\":\"1\",\"cell\":[\"\"]}," +
                "{\"id\":\"2\",\"cell\":[\"\"]}," +
                "{\"id\":\"3\",\"cell\":[\"\"]}," +
                "{\"id\":\"4\",\"cell\":[\"\"]}," +
                "{\"id\":\"5\",\"cell\":[\"\"]}," +
                "{\"id\":\"6\",\"cell\":[\"\"]}," +
                "{\"id\":\"7\",\"cell\":[\"\"]}," +
                "{\"id\":\"8\",\"cell\":[\"\"]}," +
                "{\"id\":\"9\",\"cell\":[\"\"]}," +
                "{\"id\":\"10\",\"cell\":[\"\"]}" +
            "]}";

并将其加载到具有datatype:jsonstring和datastr:d的网格中，其中我们的网格有15列，每列都是使用自定义格式程序创建的.

And loading that into a grid with datatype:jsonstring and datastr:d where our grid has 15 columns and each column is created using a custom formatter.

有更好的方法吗?

推荐答案

对应于

Correspond to the documentation (see description of the data parameter)

它可以代替addRowData方法 相对大数据的速度慢

It can replace addRowData method which is slow on relative big data

我自己没有进行任何测量，但是使用data参数似乎也是最有效的方法之一.要添加多少行数据很重要.与datatype:jsonstring一起使用的参数datastr是相对较旧的方式，在3.7版中引入本地数据分页之前.关于data参数，您可以添加大组纯数据，对其进行排序并显示数据的第一页.对于addJSONData函数，将使用来自data参数的数据填充第一页，因此在所有情况下，工作部分都是相同的.仅填充大小随页面大小而变化的数据才能使使用data参数的方式更有效.

I don't made any measure myself, but the usage of data parameter seems me also as one of the most effective ways. It is important how many rows of data you want to add. The parameter datastr used together with datatype:jsonstring is relatively old way existing before introducing in the version 3.7 the local paging of data. With respect of the data parameter you can add large set of pure data, sort it and display the first page of the data. The filling of the first page with the data from the data parameter will be done with respect of addJSONData function so the part of work is the same in all cases. Only the filling of data which size is grater as the page size makes the way with the data parameter more effective.

如果要使用data参数，则不要忘记在数据数组中定义其他id属性.它可以是具有默认id名称的属性，也可以是localReader中定义的其他名称.如果为jqGrid的一列定义了key:true，则不需要包含其他id属性.

If you will use data parameter you should don't forget to define additional id property in the data array. It can be either the property with default id name or another name defined in localReader. If you defined key:true for one column of the jqGrid, then including of additional id property is not needed.
