如何将带有/的URL传递给JavaScript对象?

问题描述

我有一个简单的AJAX/JavaScript函数，该函数会发出GET请求，并在成功的情况下根据URL将页面加载到当前页面中:

I have a simple AJAX/JavaScript function which makes a GET request and loads a page into the current page based on a URL if successful:

function loadDoc(myUrl) {
                    var xhttp = new XMLHttpRequest();
                    xhttp.onreadystatechange = function () {
                        if (this.readyState == 4 && this.status == 200) {
                            document.getElementById("toolOptions").innerHTML =
                                    this.responseText;
                        }
                    };

                    xhttp.open("GET", myUrl, true);
                    xhttp.send();
 }

稍后我将在同一文档中调用此函数:

And I'm calling the function later on in the same document with this:

< li onclick ="loadDoc(/myUrl/toTheLocalSever)">将数据集添加到视图</li>

(URL是由Scala Play的反向路由生成的，但这正是它在最终源中呈现的方式-因此，我认为Play不是这里的问题).

(the URL is generated by Scala Play's reverse routing, but this is exactly how it renders in the final source - so I don't think Play is the issue here).

但是，每当执行此操作时，我都会在控制台中得到它:

But, whenever I do this, I get this in my console:

SyntaxError:正则表达式标志d

我认为这是引号的问题，所以我在原始函数 loadDoc(myUrl)中做到了:

I thought it was an issue with the quotes, so I did this in the original function loadDoc(myUrl):

var wrappedUrl = "'"+myUrl+"'"
xhttp.open("GET", wrappedUrl, true);

但是那仍然给我同样的错误.我究竟做错了什么?谢谢！

But that still gives me the same error. What am I doing wrong? Thanks!

推荐答案

是的.

您正在尝试编写不带任何字符串的文字.

You are trying to write a string literal without any.

onclick="loadDoc("/myUrl/toTheLocalSever")">

var wrappedUrl = "'"+myUrl+"'"

您无法从引发错误后运行的代码中修复语法错误.

You can't fix a syntax error from code that runs after the error has been thrown.
