我正在使用kendo ui网格来显示数据。我能够获得我想在对象数组中使用的过滤器
Object {logic: "and", filters: Array[3]}
filters:Array[3]
0:Object
field:"CheckDate"
operator:"gte"
value:Fri Jan 01 2016 00:00:00 GMT-0500 (Eastern Standard Time)
1:Object
field:"CheckDate"
operator:"lte"
value:Tue Jan 31 2017 00:00:00 GMT-0500 (Eastern Standard Time)
我无法弄清楚如何循环遍历此数组并使用过滤器内部的值来获取kendo网格。过滤器代码如下所示:
grid.dataSource.filter({
logic: "and",
filters: [
{ field: "EmployeeName", operator: "contains", value: val }
]
});
我必须为数组中的每个项目添加一行来应用过滤器。

您是否要求for ... in
声明?如果订单不重要,我会使用它。
for (var val in yourObject.filters){
grid.dataSource.filter({
logic: "and",
filters: [
{ field: val[0], operator: val[1], value: val[2] }
]
});
};

如果您习惯编写C#或Java代码,Javascript for ... in
的行为非常奇怪,因此我更倾向于使用jQuery.each,其行为与我期望的一样。
$.each(yourObject.filters, function(index, element){
grid.dataSource.filter({
logic: "and",
filters: [
{ field: element[0], operator: element[1], value: element[2] }
]
});
});

对象Object {logic: "and", filters: Array[3]}
的结构实际上是kendo数据源期望进行过滤的结果。但是,要手动执行此操作,您可以尝试以下操作,
var generateFilterArray = function (yourFilterObject) {
var filters = []
for (var i = 0; i < yourFilterObject.filters.length; i++) {
filters.push({
field: yourFilterObject.filters[i].field,
operator: yourFilterObject.filters[i].operator,
value: yourFilterObject.filters[i].value
});
}
return {
logic: yourFilterObject.logic,
filters: filters
};
}
grid.dataSource.filter(generateFilterArray(yourFilterObject))
最后,记住不要在循环中调用grid.dataSource.filter(),因为它会多次调用远程端点,所以总是首先创建过滤器对象然后按上面的方式应用它
