Question

I have 4 arraylist in jsp and I want to get elements of lists from javascript function.

it looks like there is no problem getting one element from jsp arraylist.

But I don’t know how to move multiple or all elements from jsp arraylist to javascript code.

below is my code

<script>
    function makeTable(){
    for(c=0;c<row_num;c++){
        row[c]=document.createElement('tr'); 
        for(k=0;k<cell_num;k++) {
            cell[k]=document.createElement('td');
            cont = document.createElement('a');
            cont.href="./bbs_view.jsp?count=" + c;
            cont.innerHTML ="<%=title.get(0)%>";
            cell[k].appendChild(cont);
            row[c].appendChild(cell[0]);
        }
    }
}
</script>

as you can see, above function can get only one element from jsp arraylist.
is there any way to replace <%=title.get(0)%> to
something like <%=title.get( javascript var c)%>?

Answer 1

Emit a javascript array within your scriplet (assumin titles is a java collection of Strings) and use the js counterpart of your array.

<script>

var jsArray = [];

<% int i = 0; foreach (String iterat : titles) { %>

jsArray[<%= i %>] = '<%= iterat %>';

<% i++; } %>
</script>

Is roughly unelegant (better have this in a custom tag, but should work).

BEWARE: typed on the fly, can have syntax typos in ^^
