数据表格jqGrid中的formatter 详细

jqGrid中对列表cell属性格式化设置主要通过colModel中formatter、formatoptions来设置

基本用法：

1.jQuery("#jqGrid_id").jqGrid({  
2....  
3.   colModel: [   
4.      ...   
5.      {name:'price', index:'price',  formatter:'integer', formatoptions:{thousandsSeparator: ','}},  
6.      ...  
7.   ]  
8....  
9.});  

 

formatter主要是设置格式化类型(integer、email等以及函数来支持自定义类型),formatoptions用来设置对应formatter的参数，jqGrid中预定义了常见的格式及其options：

integer

thousandsSeparator： //千分位分隔符,

defaulValue

number

decimalSeparator, //小数分隔符，如"."

thousandsSeparator, //千分位分隔符，如","

decimalPlaces, //小数保留位数

defaulValue

currency

decimalSeparator, //小数分隔符，如"."

thousandsSeparator, //千分位分隔符，如","

decimalPlaces, //小数保留位数

defaulValue,

prefix //前缀，如加上"$"

suffix//后缀

date

srcformat, //source的本来格式

newformat //新格式

email

没有参数，会在该cell是email加上： mailto:[e-mail]

showlink

baseLinkUrl, //在当前cell中加入link的url，如"jq/query.action"

showAction, //在baseLinkUrl后加入&action=actionName

addParam, //在baseLinkUrl后加入额外的参数，如"&name=aaaa"

target,

idName //默认会在baseLinkUrl后加入,如".action?id=1"。改如果设置idName="name",那么".action?name=1"。其中取值为当前rowid

checkbox

disabled //true/false 默认为true此时的checkbox不能编辑，如当前cell的值是1、0会将1选中

select

设置下拉框，没有参数，需要和colModel里的editoptions配合使用

下面是一个使用的例子:

1.var datas = [  
2.                  {"id":1,  "name":"name1",  "price":123.1,     "email":"[e-mail]",  "amount":1123423,   "gender":"1", "type":"0"},  
3.                  {"id":2,  "name":"name2",  "price":1452.2,    "email":"[e-mail]",  "amount":12212321,  "gender":"1", "type":"1"},  
4.                  {"id":3,  "name":"name3",  "price":125454,    "email":"[e-mail]",  "amount":2345234,   "gender":"0", "type":"0"},  
5.                  {"id":4,  "name":"name4",  "price":23232.4,   "email":"[e-mail]",  "amount":2345234,   "gender":"1", "type":"2"}]  

 

1.colModel:[  
2.    {name:'id',     index:'id',     formatter:  customFmatter},  
3.    {name:'name',   index:'name',   formatter: "showlink", formatoptions:{baseLinkUrl:"save.action",idName: "id", addParam:"&name=123"}},  
4.    {name:'price',  index:'price',  formatter: "currency", formatoptions: {thousandsSeparator:",",decimalSeparator:".", prefix:"$"}},  
5.    {name:'email',  index:'email',  formatter: "email"},  
6.    {name:'amount', index:'amount', formatter: "number", formatoptions: {thousandsSeparator:",", defaulValue:"",decimalPlaces:3}},        
7.    {name:'gender', index:'gender', formatter: "checkbox",formatoptions:{disabled:false}},  
8.    {name:'type',   index:'type',   formatter: "select", editoptions:{value:"0:无效;1:正常;2:未知"}}  
9.],  

 其中customFmatter声明如下

1.function customFmatter(cellvalue, options, rowObject){  
2.    console.log(cellvalue);  
3.    console.log(options);  
4.    console.log(rowObject);  
5.    return "["+cellvalue+"]";  
6.};  

 在页面显示的效果如下：

 当然还得支持自定义formatter函数，只需要在formatter:customFmatter设置formatter函数，该函数有三个签名

1.function customFmatter(cellvalue, options, rowObject){  
2.      
3.}  
4.//cellvalue - 当前cell的值  
5.//options - 该cell的options设置，包括{rowId, colModel,pos,gid}  
6.//rowObject - 当前cell所在row的值，如{ id=1, name="name1", price=123.1, ...}  

 当然对于自定义formatter，在修改时需要获取原来的值，这里就提供了unformat函数，这里见官网的例子：

1.jQuery("#grid_id").jqGrid({  
2....  
3.   colModel: [   
4.      ...   
5.      {name:'price', index:'price', width:60, align:"center", editable: true, formatter:imageFormat, unformat:imageUnFormat},  
6.      ...  
7.   ]  
8....  
9.});  
10.   
11.function imageFormat( cellvalue, options, rowObject ){  
12.    return '<img src="'+cellvalue+'" />';  
13.}  
14.function imageUnFormat( cellvalue, options, cell){  
15.    return $('img', cell).attr('src');  
16.}
