calling Javascript function in JSP
提问by newbie
I'm trying to call a function and activate an alert through it in my JSP.
This is what i've done so far:
我试图在我的 JSP 中调用一个函数并通过它激活一个警报。
这是我到目前为止所做的：
<html>
<head>
<script type="text/javascript">
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
function myFunction( test )
{
alert( test );
}
</script>
<title>Success</title>
</head>
<body>
<c:set var="test" scope="request" value="${requestScope.userDetails }"></c:set>
<input type="button" id="sample_button" onclick="myFunction(${test.userName})" value="test">
</body>
</html>
What is wrong with my code?
我的代码有什么问题？

In addition to that, You might also need to add a single quote inside the calling function
除此之外，您可能还需要在调用函数中添加单引号
<input type="button" id="sample_button" onclick="myFunction('${test.userName}')" value="test">

You had a metaelement inside scriptelement which will throw an error while parsing the script block
您在metaelement 中有一个元素，script它会在解析脚本块时抛出错误
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<script type="text/javascript">
function myFunction( test )
{
alert( test );
}
</script>
<title>Success</title>
</head>
<body>
<c:set var="test" scope="request" value="${requestScope.userDetails }"></c:set>
<input type="button" id="sample_button" onclick="myFunction(${test.userName})" value="test" />
</body>
</html>
