符合$ OR

Question

在MongoDB中我有2个条件

• 第一个条件：

  "\"userfullname\":{$regex : \"" + filtertext +  "\", $options: 'i'}";
  

• 第二个条件：

  "\"email\":{$regex : \"" + filtertext +  "\", $options: 'i'}";
  

我需要对此声明进行OR条件，所以我所做的是：

matchquery = matchquery + "\"userfullname\":{$regex : \"" + filtertext +  "\", $options: 'i'}"+["%OR:"]+"\"email\":{$regex : \"" + filtertext +  "\", $options: 'i'}";

但当然没有用。我怎样才能做到这一点？

Answer 1

使用 $or 运算符。您基本上想要创建一个具有

形式的查询

[(ngModel)]="user.name"

如果var matchquery = { '$or': [ { 'userfullname': { '$regex': \filtertext\, '$options': 'i' } }, { 'email': { '$regex': \filtertext\, '$options': 'i' } } ] } 是变量，则可以使用 RegExp 构造函数创建正则表达式对象，以便将文本与模式匹配。例如：

filtertext

要对查询进行字符串化，您可以尝试：

var filtertext = "foo";
var rgx = new RegExp(filtertext, "i");
var matchquery = {
    "$or": [
        { "userfullname": rgx },
        { "email": rgx }
    ]
};

Answer 2

使用Or运算符＆amp;像这样创建它：

<script>
                            $(function () {

                                var employeeNameList = [
                                    "Abishek Chandrasekar", "Bharat", "Deepak", "Eric",
                                        "Fizil", "Gowtham", "Harbajan",
                                        "Akshara", "Roshini"
                                ];

                                var employeeIDList = [
                                    "SF1010", "SF2010", "SF3010", "SF4010",
                                        "SF5010", "SF6010", "SF7010",
                                        "SF9010", "SF8010"
                                ];

                                var emaiIDList = [
                                    "abishek.chandrasekar@syncfusion.com", "bharath@syncfusion.com", "deepak@syncfusion.com", "eric@syncfusion.com",
                                        "fizil@syncfusion.com", "gowtham@syncfusion.com", "harbajan@syncfusion.com",
                                        "akshara@syncfusion.com", "roshini@syncfusion.com"
                                ];
                                $('#EmployeeNameSearch').ejAutocomplete({
                                    width: "800px",
                                    dataSource: employeeNameList /*I wanna change this list namebased on the selected category in dropdown*/
                                });
});
