Converting some PHP code to javascript (foreach equivalent)

For each in a array. How to do that in javascript?
Hey I was needing some help with finding a good for each equivalent from PHP to javascript. I've tried using jQuery.each() but I'm not sure I've done it correctly.
Here is the code I've been needing to convert. I need to fix each foreach to 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.";
}
}
如果您正在寻找处理数据集的函数（例如foreach ），那么underscore.js是个不错的选择。
