jqGrid:多词搜索和全局搜索

更新时间:2023-10-27 16:05:46

我认为可以相对容易地将我之前建议的两种解决方案结合起来. 生成的演示允许进行全局搜索(在任何可搜索列中搜索)用于多字文本(多个值除以空格):

I think that one can relatively easy combine two solutions which I suggested before. The resulting demo allows to make global search (search in any searchable column) for multi-word text (multiple values divided by space separator):

我在演示中使用的完整代码如下:

The full code which I used in the demo is below:

$(function () {
    "use strict";
    var mydata = [
            { id: "1",  invdate: "2007-10-21", name: "test",   note: "3note",   amount: "200.00", tax: "10.00", closed: true,  ship_via: "TN", total: "210.00" },
            { id: "2",  invdate: "2007-10-22", name: "test2",  note: "3note2",  amount: "300.00", tax: "20.00", closed: false, ship_via: "FE", total: "320.00" },
            { id: "3",  invdate: "2007-09-01", name: "test3",  note: "3note3",  amount: "400.00", tax: "30.00", closed: false, ship_via: "FE", total: "430.00" },
            { id: "4",  invdate: "2007-10-14", name: "test4",  note: "3note4",  amount: "200.00", tax: "10.00", closed: true,  ship_via: "TN", total: "210.00" },
            { id: "5",  invdate: "2007-10-31", name: "test5",  note: "3note5",  amount: "300.00", tax: "20.00", closed: false, ship_via: "FE", total: "320.00" },
            { id: "6",  invdate: "2007-09-06", name: "test6",  note: "3note6",  amount: "400.00", tax: "30.00", closed: false, ship_via: "FE", total: "430.00" },
            { id: "7",  invdate: "2007-10-04", name: "test7",  note: "3note7",  amount: "200.00", tax: "10.00", closed: true,  ship_via: "TN", total: "210.00" },

已更新:要允许在全局搜索字符串中使用带引号的字符串和空格,可以使用match代替split. 修改后的演示允许使用以下

UPDATED: To allow to use quoted strings with spaces in the global searching string you can use match instead of split. The modified demo allows to use the following
