jqGrid ColModel详解

colModel：最重要的数组之一，用于设定各列的参数。

colModel也有许多非常重要的选项，在使用搜索、排序等方面都会用到。这里先只说说最基本的。

• name：为Grid中的每个列设置唯一的名称，这是一个必需选项，其中保留字包括subgrid、cb、rn。

• index：设置排序时所使用的索引名称，这个index名称会作为sidx参数（prmNames中设置的）传递到Server。

• label：当jqGrid的colNames选项数组为空时，为各列指定题头。如果colNames和此项都为空时，则name选项值会成为题头。

• width：设置列的宽度，目前只能接受以px为单位的数值，默认为150。

• sortable：设置该列是否可以排序，默认为true。

• search：设置该列是否可以被列为搜索条件，默认为true。

• resizable：设置列是否可以变更尺寸，默认为true。

• hidden：设置此列初始化时是否为隐藏状态，默认为false。

• formatter：预设类型或用来格式化该列的自定义函数名。常用预设格式有：integer、date、currency、number等

colNames:['ID','角色名称', '角色说明'],

colModel:[

    {name:'ID', index:'ID',width:55,sortable:false,hidden:true},

    {name:"LBMC",width:80,sortable:false},

    {name:"SM",width:80,sortable:false}

],

var rowId = $("#gridTable").getGridParam('selrow');

var rowData = $("#gridTable").getRowData(rowId);

jqGrid就是通过rowId来选择执行其他操作，而不是rowData.ID

注意：rowId是指table tr.id

如果colModel的属性中有name:'id'（小写，从数据库里面读出来的），这个值会把table tr的id覆盖了。此时rowId == rowData.id。

如果colModel的属性中没有有name:'id',会自动生成tr.id

jqGrid生成的源码如下：

<table id="gridTable" class="ui-jqgrid-btable" cellspacing="0" cellpadding="0" tabindex="1" role="grid" aria-multiselectable="true" aria-labelledby="gbox_gridTable" style="width: 1144px;">

<tbody>

<tr id="1" class="ui-widget-content jqgrow ui-row-ltr bgeaeff1" role="row" tabindex="-1">

    <td aria-describedby="gridTable_cb" style="text-align:center;width: 20px;" role="gridcell">

        <input id="jqg_gridTable_1" class="cbox" type="checkbox" name="jqg_gridTable_1" role="checkbox">

    </td>

    <td aria-describedby="gridTable_ID" title="4028818d2e8a1592012e8a1c1c0e0003" style="display:none;"             role="gridcell">4028818d2e8a1592012e8a1c1c0e0003</td>

    <td aria-describedby="gridTable_LBMC" title="2" style="" role="gridcell">2</td>

    <td aria-describedby="gridTable_SM" title="2" style="" role="gridcell">2</td>

</tr>

</tbody>

ColModel是jqGrid里面最核心的属性。大部分配置都在这里面进行。所有的属性的含义对应如下：

Property	Type	Description	Default
align	string	Defines the alignment of the cell in the Body layer, not in header cell. Possible values: left, center, right. 定义单元格对齐方式；可选值：left, center, right。例如： {name:’id’,align:’left’},实现左对齐。	left
classes	string	This option allow to add classes to the column. If more than one class will be used a space should be set. By example classes:’class1 class2′ will set a class1 and class2 to every cell on that column. In the grid css there is a predefined class ui-ellipsis which allow to attach ellipsis to a particular row. Also this will work in FireFox too. 置列的css。多个class之间用空格分隔，如：’class1 class2′ 。表格默认的css属性是ui-ellipsis。这个属性在火狐浏览器中也是有效的。	empty string
datefmt	string	Governs format of sorttype:date (when datetype is set to local) and editrules {date:true} fields. Determines the expected date format for that column. Uses a PHP-like date formatting. Currently ”/”, ”-”, and ”.” are supported as date separators. Valid formats are: y,Y,yyyy for four digits year YY, yy for two digits year m,mm for months d,dd for days. 当sorttype为date和编辑规则的date为true是有效。使用的格式和php一样。默认为Y-m-d	ISODate (Y-m-d)
defval	string	The default value for the search field. This option is used only in Custom Searching and will be set as initial search. 查询字段的默认值。这个选项只在自定义所属中有效。	empty
editable	boolean	Defines if the field is editable. This option is used in cell, inline and form modules. 设定是否可以对单元格进行编辑{name:’id’,index:’id’, width:180,editable:true},	false
editoptions	array	Array of allowed options (attributes) for edittype option editing 编辑的一系列选项。{name:’__department_id’,index:’__department_id’,width:200,editable:true,edittype:’select’,editoptions:{dataUrl:”${ctx}/admin/deplistforstu.action”}},这个是演示动态从服务器端获取数据。	empty array
editrules	array	sets additional rules for the editable field editing 编辑的规则{name:’age’,index:’age’, width:90,editable:true,editrules:{edithidden:true,required:true,number:true,minValue:10,maxValue:100}},设定年龄的最大值为100，最小值为10，而且为数字类型，并且为必输字段。	empty array

fixed	boolean	If set to true this option does not allow recalculation of the width of the column if shrinkToFit option is set to true. Also the width does not change if a setGridWidth method is used to change the grid width. 如果设定为true的话，单元格的大小将无法进行调整（即不可更改其宽度），同样，调用setGridWidth的方法也不会改变其大小。	false
formoptions	array	Defines various options for form editing. form编辑的一些选项	empty
formatoptions	array	Format options can be defined for particular columns, overwriting the defaults from the language file. See Formatter for more details. 对某些列进行格式化的设置	none
