jqGrid中的formatter,表格中值的格式化

jqGrid中的formatter,表格中值的格式化

jqGrid中对列表cell数次那个格式话设置主要通过colModel中formatter,formatoptions来设置。
基本用法:

Js代码

jQuery("#jqGrid_id").jqGrid({  
  ...  
 colModel: [   
  ...   
  {name:'price', index:'price',  formatter:'integer', formatoptions:{thousandsSeparator: ','}},  
  ...  
 ]  
...  
});  

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
    thousandSeparator://千分位分隔符,
    defaulValue
number
  decimalSeparator,//小数分隔符,如"."
  tousandsSwparator,//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:[email protected]

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:

Java代码

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

Js代码

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

],

其中customFmatter声明如下

Js代码

 function customFmatter(cellvalue, options, rowObject){  
console.log(cellvalue);  
console.log(options);  
console.log(rowObject);  
return "["+cellvalue+"]";  

};

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

Js代码

function customFmatter(cellvalue, options, rowObject){  
  
}  

//cellvalue - 当前cell的值
//options - 该cell的options设置,包括{rowId, colModel,pos,gid}
//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:

Js代码

jQuery("#grid_id").jqGrid({  
...  
   colModel: [   
  ...   
  {name:'price', index:'price', width:60, align:"center", editable: true, formatter:imageFormat, unformat:imageUnFormat},  
    ...  
 ]  
...  
});  
 
function imageFormat( cellvalue, options, rowObject ){  
    return '';  
}  
function imageUnFormat( cellvalue, options, cell){  
      return $('img', cell).attr('src');  
}
