我有以下 JQuery：
$(function() { $('input[type=radio]').click(function() { var r_id = $("input[@name=sc]:checked").attr( 'id'); //alert(r_id);

        if (r_id == "bName") {
            //enable By Name drop down
            $(".dName").prop('disabled', false);
            //disable By Specialty and By Status drop down
            $(".dSpecialty").prop('disabled', true);
            $(".dStatus").prop('disabled', true);
        }
        if (r_id == "bSpecialty") {
            //enable By Specialty drop down
            $(".dSpecialty").prop('disabled', false);
            //disable By Name and By Status drop down
            $(".dName").prop('disabled', true);
            $(".dStatus").prop('disabled', true);
        }
        if (r_id == "bStatus") {

            $(".dSpecialty").prop('disabled', true);

下面的 CSS 代码：

.displayresult {
    display: none;
}

现在如果你检查JS代码，下面的Doctor有多个专业：

...
{
"firstName": "Ahmad",
"lastName": "Faqir",
"status": "Provisional",
"specialty": ["Internal Medicine", "Pediatrics"],
"address": "test test, Brooklyn NY 11218",
"phone": "456.673.4389"
}
...

当用户选择“内科”或“儿科”作为专业时，如何更改 JQuery 功能以确保他同时出现两种选择？

以下JS也不起作用：

...
                if (i == $(".dStatus").find('option:selected').attr('id')) { //if what's in the phyList array matches selection
                    fname = fname + phyList[test].firstName + "<br>";
                    lname = lname + phyList[test].lastName + "<br>";
                    stats = stats + phyList[test].status + "<br>";
                    spec = spec + phyList[test].specialty + "<br>";
                    addr = addr + phyList[test].address + "<br>";
                    phonen = phonen + phyList[test].phone + "<br>";

                    document.getElementById('first').innerHTML = fname;
                    document.getElementById('last').innerHTML = lname;
                    document.getElementById('status').innerHTML = stats;
                    document.getElementById('specialty').innerHTML = spec;
                    document.getElementById('address').innerHTML = addr;
                    document.getElementById('phone').innerHTML = phonen;
                    //alert ("ok");
                    document.getElementById('errorst').innerHTML = "";
                }
                else {
                    document.getElementById('errorst').innerHTML = "<i>No match found</i>";
                }
            }
...

无论是否找到匹配项，它始终显示未找到匹配项消息。

如何使它仅在未找到匹配项时显示消息？

您可能遇到问题的原因是因为您从未声明 i。你的 for 循环应该像这样开始：

for (test=0;test<=phyList.length-1;test++) {
   var i = phyList[test].specialty; //get all specialty in the array

如果有多个专业，这将为您提供一个数组，因此您应该使用第二个 for 循环来遍历您的专业。

for ( var iVar; iVar < i.length; iVar++ )
{
    if (i[iVar] == $(".dStatus").find('option:selected').attr('id')) { //if what's in the phyList array matches selection
        //code
    }
}

这应该检查每个医生的所有专业。

由于并非所有特长都作为数组添加，因此您需要在 for 循环之外包含原始 if 语句。这是一个有效的 jQuery：http: //jsfiddle.net/k7jhq/

只是一个简化示例，说明您可以使用.map()来查找正确的对象。

// value of dropdown
var spe = $('#test').val();

var matchedPhy = $.map(phyList, function (v, i) {
    // return object if string matches or string is in array
    return v.specialty == spe || $.inArray(spe,v.specialty) > -1 ? v: null;
});

if(matchedPhy.length){
    // found some results
}else{
    // found no results
}
