本文介绍了一种JavaScript方法，用于移除数组末尾的所有0.00字符串值。通过反转数组并从后向前遍历检查每个元素的方式实现，一旦遇到非0.00即停止删除。

//原始数据
 arr: [ "1.10", "1.30", "1.37", "2.11", "1.47", "1.32", "1.58","1.59", "1.39", "2.36", "0.00", "0.00"],
 //最终数据
arrNew: ["1.10", "1.30", "1.37", "2.11", "1.47", "1.32", "1.58", "1.59", "1.39", "2.36"]
//=>将数组末尾为 "0.00" 的数据全部去除

var arr=[ "1.10", "1.30", "1.37", "2.11", "1.47", "1.32", "1.58","1.59", "1.39", "2.36", "0.00", "0.00"]
function getNumber(){
	console.log("原始数据", arr);//[ "1.10", "1.30", "1.37", "2.11", "1.47", "1.32", "1.58","1.59", "1.39", "2.36", "0.00", "0.00"]
    var data = arr.reverse(); //reverse 改变原数组
    for (let i = 0, len = data.length; i < len; i++) {
      if (data[i] == "0.00") {
        data.splice(i, 1); //splice 删除 改变原数组
        i--; //删除一个元素后数组长度减一了
      } else {
        break; //不满足条件，中断循环
      }
    }
    // console.log("最终数据", data.reverse());//["1.10", "1.30", "1.37", "2.11", "1.47", "1.32", "1.58", "1.59", "1.39", "2.36"]
    return data.reverse();
}
//调用
getNumber(arr)
