前端盲人 问下 var target = elems[i].onclick; 的作用是？

@zzz6519003 給你謝了一個有Comment的.

// target 就是一個 function pointer 指向了element onclick 的action listener function.var target = elems[i].onclick;

//檢查target是否存在, 能否轉換為String
if (target && target.toString) {
    var accept = target.toString().indexOf('newagree') > -1;
    // 如果能找到 'newagree'
    if (accept) {
        //執行function: onclick event
        target.call(null);
    }
}

        var target = elems[i].onclick;
        if (target && target.toString) {
            var accept = target.toString().indexOf('newagree') > -1;
            if (accept) {
                target.call(null);
            }
        }
