jqGrid中的formatter

javascriptjqueryjqgridformatter

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：

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

thousandsSeparator： //千分位分隔符,�0�2

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:name@domain.com

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 �0�2 �0�2 //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 �0�2 �0�2 //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:

var datas = [
	              {"id":1,  "name":"name1",  "price":123.1, 	"email":"abc@163.com", 	"amount":1123423, 	"gender":"1", "type":"0"},
	              {"id":2,  "name":"name2",  "price":1452.2,  	"email":"abc@163.com",	"amount":12212321, 	"gender":"1", "type":"1"},
	              {"id":3,  "name":"name3",  "price":125454, 	"email":"abc@163.com", 	"amount":2345234, 	"gender":"0", "type":"0"},
	              {"id":4,  "name":"name4",  "price":23232.4, 	"email":"abc@163.com",  "amount":2345234, 	"gender":"1", "type":"2"}]

	   	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

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

�0�2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

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, ...}

�0�2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：

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