Javascript:函数体后面的语法错误

Question

好的,所以你知道错误,但为什么我得到它呢？当我在本地运行时,我没有任何错误,但是当我上传我的项目时,我遇到了这个恼人的语法错误.我检查了firebug错误控制台,这没有帮助,因为它把我所有的源都放在同一行,我已经通过Lint解析它似乎也没有找到问题 - 我刚刚格式化我的大括号以某种我讨厌的方式不同; 在声明的同一行,没有.

function ToServer(cmd, data) {
    var xmlObj = new XMLHttpRequest();
    xmlObj.open('POST', 'handler.php', true);
    xmlObj.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    xmlObj.send(cmd + data);
    xmlObj.onreadystatechange = function() {
        if(xmlObj.readyState === 4 && xmlObj.status === 200) {
            if(cmd == 'cmd=push') {
                document.getElementById('pushResponse').innerHTML = xmlObj.responseText;
            }
            if(cmd == 'cmd=pop') {
                document.getElementById('messages').innerHTML += xmlObj.responseText;
            }
            if(cmd == 'cmd=login') {
                if(xmlObj.responseText == 'OK') {
                    self.location = 'index.php';

                }
            }           
        }
    }

function Login() {

问题是您的服务器中的脚本是一行,并且您在其中有注释.之后的代码//将被视为评论.这就是原因.
