jQuery variable claiming it's undefined when it has been defined




问题在于,在firefox中打开它并为输入1输入值并选择它时,firebug表示未定义变量phone。我尝试在一开始就定义变量,但仍然无法正常工作。

这是jQuery:

$(document).ready(function() {

var phone;  //fix scoping
var phoneid;
var firmware;
var firmwareid;

$("#input1").autocompleteArray(["iPhone 2G","iPhone 3G","iPhone 3GS","iPhone 4","iPhone 4s"],
{   minChars:1,
    matchSubset:1,
    onItemSelect:selectPhone,
    onFindValue:findPhone,
    autoFill:true,
    maxItemsToShow:10,
    selectFirst:true,
});

$("#input2").autocompleteArray(["1.1","1.2","1.3","1.4","1.5"],
{   minChars:1,
    matchSubset:1,
    onItemSelect:selectFirmware,
    onFindValue:findFirmware,
    autoFill:true,
    maxItemsToShow:10,
    selectFirst:true,
    });



function findPhone(li) {
    if( li == null ) return alert("No match!");
    phone = li.selectPhone;
    phoneid = phone.replace("iPhone ","iphone").toLowerCase();
};

function findFirmware(li) {
    if( li == null ) return alert("No match!");
    firmware = li.selectFirmware;
    firmwareid = phone.replace(".","");
    $(".info").hide
    $(phoneid+firmware).show
};

function selectPhone(li) {
    findPhone(li);
}

function selectFirmware(li) {
    findFirmware(li);
}
    });


这是HTML:

<div id="formcontainer">
        <input id="input1"/>
        <input id="input2"/>
</div>
<div id="iphone2g11" class="info" style="display:none">iPhone 2G</div>
<div id="iphone2g12" class="info" style="display:none">iPhone 3G</div>
<div id="iphone2g13" class="info" style="display:none">iPhone 3GS</div>
<div id="iphone2g14" class="info" style="display:none">iPhone 4</div>
<div id="iphone2g15" class="info" style="display:none">iPhone 4S</div>

最佳答案

问题出在您的findFirmware()函数中,将其更改为

function findFirmware(li) {
    if( li == null ) return alert("No match!");
    firmware = li.selectFirmware;
    firmwareid = phone.replace(".","");
    $(".info").hide();
    $('#' + phoneid + firmwareid).show(); // This line was messed up
};


该行$(phoneid+firmware).show存在两个问题,如果您计算缺少的括号和分号,那么还有四个问题,但是...


您尝试显示的div有一个ID,但您的选择器中没有#即可通过ID选择元素
firmware包含带句点的未解析字符串,因此当div ID为phoneid + firmwareiphone2g1.2变为iphone2g12,因此您需要使用从中解析出firmwareid的字符串。
