  }
}

基本上这个应用程序只有在匹配数组中的所有信息时才有效，但是我想这样做，例如，如果它与模型品牌和网络的选项上的匹配很少，并根据匹配显示结果，这样就可以了示例显示来自摩托罗拉等的所有手机。另外我想给匹配％，所以这场比赛有多好:)如何做到这一点

小提琴 - https://jsfiddle.net/f45gfx2p/2/

for (var p=0;p<contract.length;p++) {
    if (brandCheck == contract[p].brand &&
        model.value == contract[p].model &&
        networkCheck == contract[p].network &&
        minutes >= contract[p].minutes &&
        e.value == contract[p].texts &&
        f.value == contract[p].data &&
        g.value == contract[p].upcost &&
        h.value == contract[p].monthlycost &&

在上面的代码中，您使用的是'and' &&运算符 - 这意味着所有内容都必须匹配 - model.value必须匹配，而networkCheck必须匹配....依此类推。依此类推。 /> 将这些切换到'or' ||运算符，您可以进行各种匹配。 model.value匹配或networkCheck匹配。或者你可以结合它们，但你认为合适。

var percentage = 0; //create a percentage variable
if(e.value){ //check if user has selected a form element
    percentage += 1; //if an element is selected add one to percentage
}
//if a user selects 4 elements out of 8 then percentage is 50%
percentage = Math.floor((percentage / 8) * 100)); //get percentage as a percentage rather than fraction
for (var p=0;p<contract.length;p++) {
        if (brandCheck == contract[p].brand ||  //<---or instead of and
            model.value == contract[p].model ||
            networkCheck == contract[p].network ||
            minutes >= contract[p].minutes ||
            e.value == contract[p].texts ||
            f.value == contract[p].data ||
            g.value == contract[p].upcost ||
            h.value == contract[p].monthlycost ||

在匹配百分比前面 - 检查有多少值以及从这些值中进行了多少次匹配。因此，如果g.value == contract[p].upcost返回true，那么8个中的1个匹配等等。
