对象没有方法拆分。

Question

HEllo的家伙们，我有一个脚本运行良好的Chrome和FF，但似乎不工作在IE.虽然它有一个java脚本错误，但我无法解决它，错误是

Uncaught :对象函数(){var b=this;var d=[];for(var a=b.ength；a-；){var c=ba;if(jQuery.inArray(c，d)==-1)d.unshift(C)}返回d}没有“拆分”方法

请帮帮忙

    function populate(s1,s2){
    var s1 = document.getElementById(s1);
    var s2 = document.getElementById(s2);
    s2.innerHTML = "";
    if(s1.value == "bedroom"){
        var optionArray = ["|Room Type","private|Private","shared|Shared","suite|Suite"];
    } else if(s1.value == "house"){
        var optionArray = ["|House Type","beach_house|Beach House","bungalow|Bungalow","cabin|Cabin","chateau|Chateau","house|House","cottage|Cottage","lake_house|Lake House","ski_chalet|Ski Chalet","townhosue|Townhouse","villa|Villa"];
    } else if(s1.value == "apartment"){
        var optionArray = ["|Appartment Type","apartment|Apartment","apartment_hotel|Apartment Hotel","condo|Condo","loft|Loft","luxury_apartment|Luxury Apartment","serviced_aparment|Serviced Apartment"];
    } else if(s1.value == "bnb"){
        var optionArray = ["|B&B Type","room|Room","suite|Suite"];
    } else if(s1.value == "hotel"){
        var optionArray = ["|Hotel Type","boutique_hotel|Boutique Hotel","budget_hotel|Budget Hotel","hotel|Hotel","inn|Inn","resort|Resort"];
    } else if(s1.value == "hostel"){
        var optionArray = ["|Hostel Type","hostel|Hostel"];
    }
    for(var option in optionArray){
        var pair = optionArray[option].split("|");
        var newOption = document.createElement("option");
        newOption.value = pair[0];
        newOption.innerHTML = pair[1];
        s2.options.add(newOption);
    }
}

Answer 1

看起来您使用的是一些扩展，它将属性添加到数组原型中，因此IE对其他浏览器没有的附加值进行操作。直接修复是针对 on your array，使用普通的for代替：

for(var i = 0; i < optionArray.length; ++i) {
    // and now use optionArray[i] instead of optionArray[option]
}

另一种选择是将这些属性过滤掉

for(var option in optionArray){
    if (!optionArray.hasOwnProperty(option)) continue;
    // the rest without modification
}

Answer 2

您是在if和一些if中定义var optionArray，但不是在泛型optionArray中，因此在某些情况下，optionArray可以是未定义的。

您可以将定义移至if的顶部，也可以定义泛型的else。

代码：

function populate(s1,s2){
    var s1 = document.getElementById(s1);
    var s2 = document.getElementById(s2);
    s2.innerHTML = "";
    var optionArray=new Array();
    if(s1.value == "bedroom"){
        optionArray = ["|Room Type","private|Private","shared|Shared","suite|Suite"];
    } else if(s1.value == "house"){
        optionArray = ["|House Type","beach_house|Beach House","bungalow|Bungalow","cabin|Cabin","chateau|Chateau","house|House","cottage|Cottage","lake_house|Lake House","ski_chalet|Ski Chalet","townhosue|Townhouse","villa|Villa"];
    } else if(s1.value == "apartment"){
        optionArray = ["|Appartment Type","apartment|Apartment","apartment_hotel|Apartment Hotel","condo|Condo","loft|Loft","luxury_apartment|Luxury Apartment","serviced_aparment|Serviced Apartment"];
    } else if(s1.value == "bnb"){
        optionArray = ["|B&B Type","room|Room","suite|Suite"];
    } else if(s1.value == "hotel"){
        optionArray = ["|Hotel Type","boutique_hotel|Boutique Hotel","budget_hotel|Budget Hotel","hotel|Hotel","inn|Inn","resort|Resort"];
    } else if(s1.value == "hostel"){
        optionArray = ["|Hostel Type","hostel|Hostel"];
    }
    for(var option in optionArray){
        var pair = optionArray[option].split("|");
        var newOption = document.createElement("option");
        newOption.value = pair[0];
        newOption.innerHTML = pair[1];
        s2.options.add(newOption);
    }
}
