if语句在我的for循环中不起作用

The if statement doesnt work in my forloop

本文关键字：循环 不起作用 for 我的 语句 if      更新时间：2023-09-26

目前我正在从事Java脚本项目。该项目用于检查从UDDF文件中选择的值与UDDF文件中的整个值。但是用于比较的if语句不起作用。我把我的代码放在

下面
function parseUddf(){
var myArray=new Array("null","airportID","airportSiteNo","faaRgn","uddfVer","null","airportName","verificationDate",
"city","state","horizontalelevationdatum","horiAccuracy","elevAccuracy","orthoDatum","orthoAccuracy",
"magDec","verificationDate","airportOrthoElev","airportEllipsoidElev","airportElevationLoc",
"verificationDate","towerFloorOrthoElev","towerFloorEllipElev","verificationDate","arpLatitude","arpLongitude");
var selt=document.getElementById("textdis").value;
var x = document.getElementById("uddf").value;
x = x.split("@");
var x0 = x[0];
x0 = x0.split("|");
var j=x0.length;
alert(j);
for(var i=1;i<x0.length;i++){
        alert("selt="+selt.toString());
    if(selt.toString()==x0[i])
 {
          alert("success");
          alert("i="+i);
          alert(myArray[i]);
//document.getElementById("textdistitleid").value=myArray[i];
 break;
    }

    }
}

UDDF文件值为:

| FAI | 50219年。[au:] [01:07|费尔班克斯国际机场|1592011||费尔班克斯|阿拉斯加nad83 |5厘米|15厘米| navd88 |25厘米|| -20.4 | 1592011 || 439.0| 470.0| 20r +3990|1592011|| 529.0| || 644854.4 | -1475123.2 |

我需要你的帮助

可以使用。equals():

代替==
selt.toString().trim().equals(x0[i].trim())

您可以从这里获得javascript的trim()函数
