I'm trying to call javascript function from a href . the function has a parameter which will be retrieved by the eval function . But some error occurs .
script:
function rate(id) {
// do something
}
the a tag that will call the function:
<a href=javascript:rate( + <%#Eval(ID)%> + ) >rate</a>
What am I missing ?
You shouldn't be doing it like this, but the issue you're currently up against is probably is your quoting/concatenating.
If <%#Eval(ID)%> simply produces an INT, this should work:
<a href=javascript:rate( <%#Eval(ID)%> ) >rate</a>
If it's a string,
<a href=javascript:rate( '<%#Eval(ID)%>' ) >rate</a>
should do it for you, although you need to handle the case of <%#Eval(ID)%> producing anything with a single quote in it.
A Lesson:
I say you shouldn't be doing it like this because the javascript pseudo protocol (javascript:) is defunct and improper. At worst you should be using an onclick which returns false. Ideally you'd be assigning the event programatically and preventing the event object's default action.
