var tName = [];
var tNumber = [];
var i = 0;
var o = document.getElementsByTagName("a")[25];
for( i=6;i <=24;i++ ){
tName.push(document.getElementsByTagName("a")[i]);
tNumber.push(document.getElementsByTagName("a")[i-1]);
if(tName[i].textContent.includes("(1001)") == true){
tName[i].style.display = "none";
tNumber[i-1].style.display = "none";
}
}
if( o.textContent.includes('(1001)') == true ){
o.style.display = "none";
}
これ実行するとTypeError: tName[i] is undefinedって出るんですが原因わかる方いますか？
実行順序の関係だろうか.
