1、jqGrid的固定写法：
<script type="text/javascript"> $(function(){ $("#list").jqGrid({参数类表}) }); </script>
2.其中参数类表是个很关键的参数，下面做一个详细的介绍
PropertyDescriptionurlTells us where to get the data. Typically this is a server-side function with a connection to a database which returns the appropriate information to be filled into the Body layer in the grid 从后台获取要显示数据的地址datatypeThis tells jqGrid the type of information being returned so it can construct the grid. In this case, we tell the grid that we expect xml data to be returned from the server, but other formats are possible. For a list of all available datatypes refer to API Methods告诉我们数据的类型json、xml等格式还可以本地mtypeTells us how to make the ajax call: either 'GET' or 'POST'. In this case, we will use the GET method to retrieve data from the server获取数据的方法colNamesAn array in which we place the names of the columns. This is the text that appears in the head of the grid (Header layer). The names are separated with commas为一个数组，用来显示的头部标题colModelAn array that describes the model of the columns. This is the most important part of the grid. Here I explain only the options used above. an array that describes the model of the columns. This is the most important part of the grid. Here I explain only the options used above. For the complete list of options see colModel API name the name of the column. This name does not have to be the name from database table, but later we will see how we can use this when we have different data formats列的名字 index the name passed to the server on which to sort the data (note that we could pass column numbers instead). Typically this is the name (or names) from database – this is server-side sorting, so what you pass depends on what your server expects to receive索引也就是你的这一列的排列顺序 width the width of the column, in pixels行的宽度（默认） align the alignment of the column排列的方式居中还是靠左 sortable Specifies if the data in the grid can be sorted on this column; if false, clicking on the header has no effect（是否可以排续）
pagerDefines that we want to use a pager bar to navigate through the records. This must be a valid html element; in our example we gave the div the id of “pager”, but any name is acceptable. Note that the Navigation layer (the “pager” div) can be positioned anywhere you want, determined by your html; in our example we specified that the pager will appear after the Body layer.显示页数rowNumSets how many records we want to view in the grid. This parameter is passed to the url for use by the server routine retrieving the datarowListAn array to construct a select box element in the pager in which we can change the number of the visible rows. When changed during the execution, this parameter replaces the rowNum parameter that is passed to the url
sortnameSets the initial sorting column. Can be a name or number. This parameter is added to the url for use by the server routineviewrecordsDefines whether we want to display the number of total records from the query in the pager barcaptionSets the caption for the grid. If this parameter is not set the Caption layer will be not visible连接地址：http://www.trirand.com/jqgridwiki/doku.php?id=wiki:first_grid#behind_the_scenesgrid_data
