Passing json to javascript method from aspx

Question

Im trying to pass to javascript method declared in my aspx page , a json as string,

    <a href="javascript: void(0)" onclick="javascript: JsonParser('{"root":"assd3444"}')">

but i got always same error:

Uncaught SyntaxError: Invalid or unexpected token

in the same row that i posted above, in browser.

Method is empty and declared in top of the page :

  function JsonParser(jsonString) {
            debugger;
            // do something with json
        }

How i can pass json string to a javascript method from aspx ?

I have also tried to put \ before double quotes in json string but it still doesn't work.

Thanks
