我在这里看到过很多与此类似的问题,但似乎没有一个问题可以解决我遇到的问题。 我一直收到以下错误 -
未捕获的SyntaxError:意外的令牌<
它说错误是在js文件的第一行,但是源只在html文件的第一行显示一条红线。
还应该提到它在go go服务器上运行。
谢谢你!
这是我的HTML

这是我的js
const form = $("#userInput");
const listItem = $("#list-group");
//add the keypress function for when the user types an input for eliza to compute
$(document).ready(()=>{
form.keypress(function(event){
const keyCodes = {
ENTER : 13
}
let keyCode = event.keyCode;
//for enter
if(event.keyCode != keyCodes.ENTER){
return;
}
event.preventDefault();
const input = form.val();
form.val(" ");
listItem.append("<li class='list-group-item list-group-item-success'>"+"User : " + input + "</li>");
// GET/POST
const queryParams = {"userInput" : input }
$.get("/Chat", queryParams)
.done(function(response){
var nextListItem = "<li class='list-group-item list-group-item-info'>"+"ELiza : " + response + "</li>";
setTimeout(function(){

}).fail(function(){

list.append(nextListItem);
});
});

答案 0 :(得分:1)
您的网络服务器是否恰好有规则,如果找不到所请求的资源,它将默认为index.html文件提供服务?这是单页应用程序的常用配置。
如果是这种情况,如果服务器找不到请求的js文件,它将提供html文件的内容,浏览器将尝试将其解析为JavaScript。由于html文件第一行的第一个字符是<
,因此您将收到语法错误,因为它不是有效的JavaScript。
