推荐答案

I want to get lowest index but I can't do that

确定您可以:0

JavaScript中任何数组的最低索引将为0.

The lowest index of any array is going to be 0 in JavaScript.

如果您有一个值数组，则可以这样获得最小值:

If you have an array of values, you can get the min as so:

var arr = [3,1,4];
Math.min.apply(Math, arr);  // returns 1

给出您的codepen示例(您应在问题中包括该示例):

Given your codepen example (which you should include in your question):

var indexes = [];
$("div").each(function(i){
   if(!$(this).hasClass("lo")){
     indexes[indexes.length]=i;
   }
});


console.log("Matches: ", indexes);
console.log("Min: ", Math.min.apply(Math,indexes));
