嘿，我需要一些帮助来为从 PHP 到 javascript 的每个等价物找到一个好的。我试过使用 jQuery.each() 但我不确定我是否正确地完成了它。
这是我一直需要转换的代码。我需要将每个 foreach 修复为 javascript。
if(calculate){
// got complete, calculate possible solution
// use decimals? Does this work in the form?
foreach(values as valName1 => val1){
foreach(operands as op1){
foreach(values as valName2 => val2){
if(valName2 == valName1)
continue;
foreach(operands as op2){
foreach(values as valName3 => val3){
if(valName3 == valName1 ||
valName3 == valName2)
continue;
foreach(operands as op3){
foreach(values as valName4 => val4){
if(valName4 == valName1 ||
valName4 == valName2 ||
valName4 == valName3)
continue;
foreach(operands as op4){
foreach(values as valName5 => val5){
if(valName5 == valName1 ||
valName5 == valName2 ||
valName5 == valName3 ||
valName5 == valName4)
continue;
parentheses = -1;
if(solve(val5, op4, val4, op3, val3, op2,
val2, op1, val1, solution, parentheses)){
count++;
// Note that since solve() just returns the first result, we won't
// display all possible parentheses ordering when there are multiple
// solutions
if(find_all){
document.write(Solution(val5, op4, val4, op3, val3, op2,
val2, op1, val1, solution, parentheses, find_all);
}
else{
document.write(Solution(val5, op4, val4, op3, val3, op2,
val2, op1, val1, solution, parentheses, find_all);
break;
}
}
parentheses = -1;
}
parentheses = -1;
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!find_all && count) break;
}
if(!count || find_all){
document.write( "Found " . count . " solutions.";
}
}
