我有一个数组,我需要从中过滤JQGrid。
var filter = ["a","b","c","d",...255];
var postData = $('jqGridName').jqGrid('getGridParam', 'postData');
jQuery.extend(postData,
{
filters: {
groupOp: "AND",
rules: [
{ field: "Types", op: "ne", data: filter[0] },
{ field: "Types", op: "ne", data: filter[1] },
{ field: "Types", op: "ne", data: filter[2] },
{ field: "Types", op: "ne", data: filter[3] },
.
.
.
{ field: "Types", op: "ne", data: filter[255] },
]
},
});
数组中的项目数不固定。但它可以包含的最大值是255。 那么我需要写入255(如上所述)还是有任何简单的方法来实现相同的目标?

我必须永久地思考自定义排序操作的问题,我承诺(在评论中)在my fork的jqGrid的未来版本中实现。最后我现在实现了这个功能。我在下面介绍它。
The first demo使用Searching Toolbar,the second demo使用Advanced Searching。两者都使用常见的jqGrid设置,允许对本地数据进行自定义搜索操作。
首先需要定义新的自定义搜索操作。我在演示IN操作中使用它允许使用多个值定义一个规则。我在“" tax"”列中使用自定义操作。它允许过滤多个值除以分号(;
)。相应的代码如下所示
$("#grid").jqGrid({
colModel: [
{ name: "tax", label: "Tax", width: 100, template: "number",
//sopt contains CUSTOM operation "nIn"
searchoptions: { sopt: ["nIn", "eq", "ne", "lt", "le", "gt", "ge", "in", "ni"] } },
...
],
customSortOperations: {
// the properties of customSortOperations defines new operations
// used in postData.filters.rules items as op peroperty
nIn: {
operand: "nIN", // will be displayed in searching Toolbar for example
text: "numeric IN", // will be shown in Searching Dialog or operation menu in searching toolbar
title: "Type multiple values separated by semicolon (";") to search for one from the specified values",
buildQueryValue: function (otions) {
// the optional callback can be called if showQuery:true option of the searching is enabled
return otions.cmName + " " + otions.operand + " (" + otions.searchValue.split(";").join("; ") + ") ";
},
funcName: "myCustomIn" // the callback function implements the compare operation
}
},
myCustomIn: function (options) {
// The method will be called in case of filtering on the custom operation "nIn"
// All parameters of the callback are properties of the only options parameter.
// It has the following properties:
// item - the item of data (exacly like in mydata array)
// cmName - the name of the field by which need be filtered
// searchValue - the filtered value typed in the input field of the searching toolbar
var fieldData = options.item[options.cmName],
data = $.map(
options.searchValue.split(";"),
function (val) {
return parseFloat(val);
}
);
return $.inArray(parseFloat(fieldData), data) >= 0;
}
});
结果,操作"nIn"
将以op
的{{1}}属性放置,就像标准filters.rules
操作一样。 jqGrid在搜索工具栏中将操作显示为"en"
(请参阅"nIN"
属性的valeu)。属性operand: "nIN"
定义了操作上显示的工具提示。
可以过滤结果,如下面的动画gif
在过滤期间,jqGrid会调用tooltip
回调。所以一个人完全可以自由地实现相应的操作。
同样可以使用高级搜索:
