javascript - javascript 中的意外标识符错误

Question

我收到以下函数的意外标识符错误。

function merge (one, two) {
    one.forEach(function(assign){

     //////////this next line is throwing the error////////////
        if (two.some(function(req) req.related == assign.rid)) {
            if (one.some(function(iter) iter.rid == req.rid)) {
                iter.quantity++;
            } else {
                one.push(req);
            }
        }
    });

    return one; 
}   

该函数旨在对对象数组进行操作。

您在 .some(function()...

周围遗漏了一些 { }

function merge (one, two) {
    one.forEach(function(assign){

        if (two.some(function(req){ req.related == assign.rid})) {
                               // ^-- This one you missed
            if (one.some(function(iter){ iter.rid == req.rid})) {
                                    // ^-- This one you missed as well
                iter.quantity++;
            } else {
                one.push(req);
            }
        }
    });

    return one; 
}
