在源网址中插入自定义值

Question

如何转义src url以插入自定义值？我的目标：

<script src="https://url.com?value=MY_ESCAPED_CUSTOM_VALUE"></script>

Answer 1

试试这个：

    var x=document.querySelector("[src^='https://url.com']");
    var url=x.getAttribute('src');
    var value=url.substring(url.lastIndexOf('='),url.length-1);
    url=url.replace(value,YOUR_CUSTOM_VALUE);
    x.setAttribute("src", url);

Answer 2

var url="https://some.url?value=" + MY_ESCAPED_CUSTOM_VALUE;
<script src={url}></script>
