As the title indicates, we will discuss how to use jQuery to retrieve parameters passed by another JSP page. In front-end development, we often encounter situations where we need to receive and process parameters passed from one page to another page. jQuery, a popular JavaScript library, is very helpful in this situation.
First, let's take a look at how to pass parameters in a JSP page. Suppose we have a page page1.jsp and want to pass parameters to another page page2.jsp. In page1.jsp, we can pass parameters through URL parameters, for example:
<a href="page2.jsp?param1=value1¶m2=value2">传递参数到page2</a>
Next, we will use jQuery in page2.jsp Get the passed parameters. We can use the URLSearchParams object to get the parameters in the URL, and then operate these parameters through jQuery. The following is a simple example:
<!DOCTYPE html>
<html>
<head>
<title>接收参数的页面</title>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
<h1>参数页面</h1>
<p id="param1"></p>
<p id="param2"></p>
<script>
$(document).ready(function() {
const params = new URLSearchParams(window.location.search);
const param1 = params.get('param1');
const param2 = params.get('param2');
$('#param1').text('参数1: ' + param1);
$('#param2').text('参数2: ' + param2);
});
</script>
</body>
</html>In the above code, we first get the parameters in the URL, and then use jQuery to display the value of the parameters on the page. When we access page2.jsp?param1=value1¶m2=value2, the page will display the passed parameter values.
Through the above example, we can see how to use jQuery to retrieve parameters passed by another JSP page. This method can help us handle the passed parameters more flexibly in front-end development and improve user experience.
