Assigning JSP variable to JavaScript

[sonu rai]

Hi All,

I am calling a javascript method in anchor tag on onclick event. my problem is , method is not called on onclick and not giving any Error.

Method----
function exportcsv1(uid){
alert("Test");
alert(uid);
}

uid is a variable of jsp

Hi,

Do the following :

    
function assign()
{
    var v = "${expression}"
    // Or you can say
    var vv = "<%= your expression %>"
}

Best of luck ...

JSP and JavaScript can't really share data since JSP is server-side code ( it runs and creates the final HTML that the browser displays ) while JavaScript is client-side code which runs on the browser.

The workaround, for values that will not change as the user work on a page is the method that Vassili Vladimir gave you above. You 'print' out the value of the server-side variable into the HTML that your send as the response.

call the function as below.
exportcsv1(<%= uid%>)

pass the value of variable uid to javascript function using expression.

it will generate html like this
exportcsv1(sud)
