将一些PHP代码转换为javascript(相当于foreach)
可能重复:
对于数组中的每一个。 如何在JavaScript中做到这一点?
嘿,我需要一些帮助,找到从PHP到JavaScript的每个等价物的好处。 我试过使用jQuery.each(),但我不确定我是否做得正确。
这是我一直需要转换的代码。 我需要修复每个foreach到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。
