好吧，我把头发扯掉了，因为我以为我已经完成了这个脚本，但是突然添加了一个 for 循环破坏了每个 indexOf，我尝试创建检查，这样控制台就不会崩溃，但遗憾的是没有成功。为“z”或 LevelCheck 使用静态值允许所有 indexOfs 正常工作，但一旦涉及 for 循环，似乎没有一个 indexOfs 希望工作
<script type="text/javascript">
var tempval = new Array();
function Renew(){ //Reset tempval back to val
for(d=0;d<val.length;d++){
tempval[d] = val[d];
}
}
function UpdateLoop(){
Renew();
var Levels = document.getElementById("Lvl");
if(Levels){
for(z=0; z<=Levels.value; z++){
Update(z);
}
}
}
function Update(LevelCheck){
for (i=0; i<=key.length; i++){
if(key[i] != null){
if ( key[i].indexOf("rate") > -1 ) { //Search through
for (r=0; r<=key.length; r++){
if(key[i].indexOf(key[r]) > -1){ //Finds out which form it should replace
var raw=tempval[i];
for (y=0; y<=key.length; y++){
if(key[i] != "movespeed" && key[i] != "Movrate"){ //add a check to see if string is not there
var item = document.getElementById(key[y]);
if (item) { //Make it use formula value and then put that result into a value and loop back into function until level reached. If level changed to a lower number, reset to original value and repeat
//raw=raw.replace(key[y],document.getElementById(key[y]).value); //replace this with val[y]
raw=raw.replace(key[y],tempval[y]);
}
}
else
break;
}
if(raw != null){
if(raw.indexOf("Mov") > -1){
for(x=0; x<=key.length; x++){
if(key[x].indexOf("movespeed") > -1){
//raw=raw.replace("Mov",document.getElementById(key[x]).value);
raw=raw.replace("Mov",tempval[x]);
break;
}
}
}
if(raw.indexOf("Lvl") > -1){
raw=raw.replace("Lvl",document.getElementById('Lvl').value);
}
if(raw.indexOf("Exp") > -1){
raw=raw.replace("Exp","0");
}
}
if( document.getElementById('Lvl').value == LevelCheck){
alert("Input:"+tempval[i]);
if(key[i] == "Movrate"){
document.getElementById("movespeed").value = eval(raw);
}
else{
var check = document.getElementById(key[r]);
if (check){
document.getElementById(key[r]).value = eval(raw);
}
}
}
else{
tempval[r] = eval(raw);
}
break; //So it doesn't keep searching
}
}
