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> 

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>

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

如果将字符串转换为小写或大写，这将是一个很好的实践，因为indexof()方法是区分大小写的。

这将是如果你的搜索不区分大小写，你可以简单地使用indexOf()方法，而不将原始字符串转换为小写或大写:

var string= location.href;
var convertedString= string.toLowerCase();

if(convertedString.indexOf('franky') != -1)
{
    alert("url has franky");
}
else
{
    alert("url has no franky");
}

if (window.location.href.indexOf("franky") != -1)

会这么做的。或者，你可以使用regexp:

if (/franky/.test(window.location.href))

变得更容易

<script type="text/javascript">
$(document).ready(function () {
    var url = window.location.href;
    if(url.includes('franky'))    //includes() method determines whether a string contains specified string.
    {
         alert("url contains franky");
    }
});
</script>
