push java array in javascript array

问题

I am getting an array char ab[16][16] through request.getAttribute in ABC.jsp:

<% char [][] ab = new char [16][16];
ab = (char [][]) request.getAttribute("grid"); %>

<script lang="text/javascript">
var cArr = new Array(16);
for(var c=0; c<16; c++)
    cArr[c] = new Array(16);
</script>

Is there a way to push values from 'ab' to cArr without doing 256 statements manually?

回答1:

<%
    String[] js = new String[16];

    for (int i=0; i<ab.length; i++) {
        js[i] = "'" + Arrays.toString(ab[i]).replace(", ", "', '") + "'";
    }

    String jsStr = Arrays.toString(js);
%>

<script lang="text/javascript">
var cArr = [
            <%= jsStr %>
            ];
</script>
