像这样:

    <script type="text/javascript">
        $(document).ready(function () {
            if(window.location.href.indexOf("cart") > -1) 
            {
                 alert("your url contains the name franky");
            }
        });
    </script>

试试这个:

<script type="text/javascript">             
    $(document).ready
    (
        function () 
        { 
            var regExp = /franky/g;
            var testString = "something.com/frankyssssddsdfjsdflk?franky";//Inyour case it would be window.location;
            if(regExp.test(testString)) // This doesn't work, any suggestions.                 
            {                      
                alert("your url contains the name franky");                 
            }             
        }
    );         
</script> 

假设您有这个脚本

<div>
  <p id="response"><p>
  <script>
    var query = document.location.href.substring(document.location.href.indexOf("?") + 1);
    var text_input = query.split("&")[0].split("=")[1];
    document.getElementById('response').innerHTML=text_input;
  </script> </div>

url表单是www.localhost.com/web_form_response.html?text_input=stack&over=flow

写入<p id="response">的文本将被堆叠

尝试indexOf

if (foo.indexOf("franky") >= 0)
{
  ...
}

您也可以尝试搜索(正则表达式)

if (foo.search("franky") >= 0)
{
  ...
}

窗口位置是一个包含多个方法和道具的对象，其中一些是与URL相关的字符串，这样你就可以安全地搜索目标字符串:

const href = location.href;
// "https://stackoverflow.com/questions/4597050/how-to-check-if-the-url-contains-a-given-string"

// another option 
const pathname = location.pathname;
// "/questions/4597050/how-to-check-if-the-url-contains-a-given-string"

// search for string safely
pathname.includes("questions"); // true
href.includes("questions"); // true

位置对象

像这样:

    <script type="text/javascript">
        $(document).ready(function () {
            if(window.location.href.indexOf("cart") > -1) 
            {
                 alert("your url contains the name franky");
            }
        });
    </script>
