通过对象数组的多个值过滤Jquery AutoComplete

Tah*_*qui 3 jquery jquery-ui autocomplete jquery-autocomplete

我想设置自动完成插件,仅选择列表中的有效员工.我有一个Employee对象数组,有EmployeeID和EmployeeName.目前,我已经通过复制数组中所有Employee的EmployeeName并将其提供给设置自动完成插件来加载EmployeeName的自动完成.

var employeeNames = new Array();
for (var i = 0 ; i < employees.length ; i++)
{
    employeeNames[a] = employees.Employee[a].Name;
}
$("#txtEmployeeName").autocomplete(employeeNames, {
    multiple: true,
    mustMatch: true,
    autoFill: true
});

它将完成工作,但我想要的是,如果用户想要在此文本框中输入EmployeeID,它也会在EmployeeID上加载建议过滤,尽管它会在建议中显示EmployeeNames.有什么方法可以实现,我记得我在某个地方看到它,但不记得网站.

如果您正在使用对象,jQueryUI需要值和/或标签字段:

支持多种类型:

数组:数组可用于本地数据.有两种支持的格式:字符串数组:["Choice1","Choice2"]

具有label和value属性的对象数组: [{label:"Choice1",value:"value1"},...] label属性显示在建议菜单中.当用户选择项目时,该值将插入到input元素中.如果仅指定了一个属性,则它将用于两者,例如,如果仅提供值属性,则该值也将用作标签.

考虑到这一点,你必须采用你的数据,包括你刚刚分配给名称的value属性(例如$.each(employees, function(){ this.value = this.name });...)

现在你需要定义的另一件事是你想要过滤的方式.这可以通过定义来完成.

例:

    $("#txtEmployeeName").autocomplete({
        source: function (request, response) {
            var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");

            var matching = $.grep(employees, function (value) {
                var name = value.value;
                var id = value.id;

                return matcher.test(name) || matcher.test(id);
            });
            response(matching);
        }
    });
