如何在JavaScript内联属性代码中引用/编写JSP变量？

Question

I need to send variables at runtime to a js method for ajax. I am trying with this onclick function but it gives syntax error on click.:

<c:set var="abc" value="${myTaglib:getAbc()}" />
<a href="#" onclick="sendAjax(${abc.firstVal}, ${abc.secVal}, ${abc.thirdVal}, ${abc.fourthVal}, ${abc.fifthVal})"> Click Here !!!</a>

Some of these values may have spaces and decimals in them. On click, I get this error at the first occurrence of space.:

SyntaxError: missing ) after argument list

The actual HTML looks like:

<a onclick="sendAjax(240265, Workplace Ethics Exam, Company Security Policy, Friends Life, ABF/45RFG, 41444.1830)" href="#">Click Here !</a>

What is wrong with this JS call ?

Answer 1

Spaces in your JavaScript code are most likely a syntax error. If your values have spaces, it's best to treat them as strings.

onclick="sendAjax('${abc.firstVal}', '${abc.secVal}', ... '${abc.fifthVal}')">

If you want to use them as numbers later, you can use the JavaScript functions parseInt and parseFloat to turn strings into numbers.

您是否尝试过在最后一个花括号后留一个空格？
