jqgrid中是否有api添加高级filter来发布数据？

我看到在这段代码中，您可以在javascript中预设postdatafilter。

postData: { filters:'{"groupOp":"AND","rules":['+ '{"field":"invdate","op":"gt","data":"2007-09-06"},'+ '{"field":"invdate","op":"lt","data":"2007-10-04"},'+ '{"field":"name","op":"bw","data":"test"}]}' } 

是否有任何API可以让你建立它。 就像是：

 jqgrid("#grid").addPostDataFilters("AND"); jqgrid("#grid").addFilteritem("field", "cn", "value"); jqgrid("#grid").addFilteritem("field1", "eq", "value2"); 

帮助生成顶部postdatafilter代码??

我试过这个，但它似乎不起作用：

 .jqGrid("setGridParam", { editurl: "/Project/UpdateMe", ondblClickRow: function (rowid) { editProject(rowid); // window.location.href="/Project/Detail/"+rowid; } }); var grid = $("#grid"); var f = { groupOp: "AND", rules: [] }; f.rules.push({ field: "Name", op: "cn", data: "volat" }); grid.p.search = f.rules.length > 0; $.extend(grid.p.postData, { filters: JSON.stringify(f) }); 

更新：

我现在有这个工作（感谢Oleg）但是，如果某个原因，Find按钮有些空白（即使我认为我有一个高级filter设置）我添加了一张图片

filter

 filters:'{"groupOp":"AND","rules":[{"field":"invdate","op":"gt","data":"2007-09-06"},{"field":"invdate","op":"lt","data":"2007-10-04"},{"field":"name","op":"bw","data":"test"}]}' 

您在问题中包含的序列化为对象的JSON版本

 var myfilter = { groupOp: "AND", rules: [ { field: "invdate", op: "gt", data: "2007-09-06" }, { field: "invdate", op: "lt", data: "2007-10-04" }, { field: "name", op: "bw", data: "test" } ] } 

这可以很容易动态构建：

 // addPostDataFilters("AND"); var myfilter = { groupOp: "AND", rules: []}; // addFilteritem("invdate", "gt", "2007-09-06"); myfilter.rules.push({field:"invdate",op:"gt",data:"2007-09-06"}); // addFilteritem("invdate", "lt", "2007-10-04"); myfilter.rules.push({field:"invdate",op:"lt",data:"2007-10-04"}); // addFilteritem("name", "bw", "test"); myfilter.rules.push({field:"name",op:"bw",data:"test"}); // generate to top postdata filter code var grid = $("#list"); grid.jqGrid({ // all prarameters which you need search:true, // if you want to force the searching postData: { filters: JSON.stringify(myfilter)} }); 

如果网格已存在，则需要使用可以使用的设置重新加载网格

 grid[0].p.search = myfilter.rules.length>0; $.extend(grid[0].p.postData,{filters:JSON.stringify(myfilter)}); grid.trigger("reloadGrid",[{page:1}]); 

代替。 大多数Web浏览器本身都支持JSON.stringify函数，但是要确保在页面上包含json2.js 。
